Sisters Swap For Christmas

Page 1

However many times we’d done it, somehow I was never quite prepared for how intense the sensation was when my husband Nathan pushed the entire length of his hard, bare cock deep into my pussy.

“Oh, fuck,” I moaned, burying my head in the pillow and breathing in the nostalgic scent of my mum’s fabric conditioner.

“Fuck, Sadie,” Nathan murmured, his body weight pinning me down onto the mattress as he lay on top of me. We’d always had difficulties doing doggy-style because Nathan was almost a foot taller than me, so there was a major mismatch in leg lengths. Through trial and error, we’d established that me lying flat on my front with him on top of me was the easiest way to do it from behind. I had no idea if this position had a name, but in my head I thought of it as reverse-missionary.

Nathan pulled his cock halfway out of me, lifting his hips, then pushed back in firmly, making me moan into the pillow again, the noise muffled. The blinds in my childhood bedroom were drawn so the room was dim, even in the middle of the day, which helped me to trick my brain into not obsessing about the fact that my parents were busy cleaning downstairs. Being overheard during sex was both my biggest fear and my biggest fantasy: I felt weird even flirting with Nathan unless there was no chance of being overheard, but quite a few of my favourite fantasies revolved around either being overheard masturbating and someone joining in, or being overheard during sex and someone joining in. Conflicted didn’t even begin to describe how I felt about it.

The reastepson I was letting my husband pick up speed and fuck me faster in a house which wasn’t completely empty was simple: for the past few months, we’d begun trying to conceive. It was the most tragically standard relationship arc in the world: we’d got married in the summer; I’d raised the idea during the honeymoon; and months later, Nathan had said he was ready and we’d stopped using condoms. I’d discovered then all the rules that governed trying for a baby and unfortunately for us, my fertile window coincided with going back to my parents’ house for Christmas. Although my preference would have been to pause things for a month, I wasn’t going to let any chances slip by.

“Mm, fuck, you’re so tight,” Nathan groaned into my ear, his forearms digging into the bed either side of my head. He shifted his weight slightly as he fucked me, trapping a strand of my hair under his arm, and I had to reach up and tug it free.

00″Fuck 0me,” I whispered, enjoying this but also hoping he didn’t need too much longer before he came inside me. I’d got him throbbing hard with a silent but sexy handjob while we snogged, which usually meant he’d explode inside me quite fast.

“Yes, Sadie, yes,” he grunted, pounding into me harder. The mattress bounced underneath us, years of use meaning it was getting soft, and I had to push my hips back into him so he could keep up the steady rhythm. The feeling of his body slapping into me from behind, his hips bumping my arse, was the best thing about this position, and I had to smother another long moan in the pillow.

“Oh fuck, I’m getting close.”

“Knock me up, babe.”

“Fuck. Okay.”

“Put a baby in me, please.”

“Fuck yes.”

“I want to get pregnant.”

“Mm fuck, Sadie-“

With a little groan of satisfaction, Nathan went rigid on top of me, buried deep in my pussy, and I lay still, pressing back into him as he came. He jerked a little, twice, tiny movements that were magnified a hundred times through my pussy, and then he sucked in a big breath and gasped.

“I love you,” he said, kissing the top of my head.

“I love you too,” I replied, mumbling a little as my head was still in full-on sex mode.

He climbed off me, making me bite my lip as his cock slid back out of me, and I just lay still as he bustled around finding his discarded clothes. I was in absolutely no rush to clean up his cum, figuring that the longer it stayed in there, the better our chances were, but I was also becoming increasingly aware of the noise of Mum vacuuming somewhere downstairs.

“If I go to the bathroom, is the coast clear?” I hissed to Nathan, who was pulling his socks back on.

“I’ll check.” He stuck his head out of my bedroom door, looked both ways, then back at me. “All clear.”

The major flaw in my parents’ house was the bedroom to bathroom ratio. They’d put up a two-bedroom extension, turning three bedrooms into five, but never put in a second bathroom. My teenage years, growing up as the youngest of three, involved a lot of hopping from foot to foot outside the bathroom door while my stepsister, Tessa, took an hour-long shower before a date. Of course, once we’d all moved out and they were in a position to do something about it, my parents didn’t need an extra bathroom any longer.

As I was cleaning up using the sink (a shower would make it far too obvious what we were up to) I thought about sex with Nathan. We’d always had fun together and we were very compatible: he probably wanted to have sex a bit more often than I did, but he took care of that by wanking over the handful of nudes I’d sent him since we started dating, which he thought he had cleverly hidden on his phone. But one time he forgot to close them, and when we were in the car later and I unlocked his phone to check the navigation, I was confronted with a picture of my own tits. I felt slightly affronted by how much he’d zoomed in on them; they were A-cups, sure, but you didn’t need a magnifying glass for fuck’s sake. Anyway, I hadn’t said anything and I’d closed it for him, relieved they were my tits and not his ex’s or something.

Now we were trying, though, we were having sex more often, especially around my fertile window, and it was becoming… well, being honest, it was less fun. It still felt good, but because everything had to lead up to him coming inside me, the foreplay had got a bit predictable. He hadn’t fingered me, or eaten my pussy, at all recently. On the other hand, I hadn’t sucked his cock either. It just felt too exhausting to do any of those things when the ‘official advice’ was to have sex as much as possible. It sounded amazing: who doesn’t want to have tons of sex? But the reality was a lot of quickies; a lot of trying hard to get myself in the right mental space, and a lot of trying to get him hard when he was sleepy or hungry or hungover.

We’d found the best routine, if you could call it that, was a handjob to get him ready, and then we went for it. It was okay, but really, my frustration was that I usually didn’t orgasm and left the bedroom more horny than I’d gone in. Just like now: trying to get washed up to rejoin the family, I wished I had fifteen minutes alone to make myself cum. I even had my vibrator in my makeup bag. But, in the only bathroom in the house, there was far too much risk of an interruption, and I was in a rush anyway. So I pulled my knickers back up my legs, pleased we’d had sex and ticked off another conception attempt, but frustrated at not getting any release.

It wasn’t really Nathan’s fault, I reflected as I gave my appearance a final once-over in the mirror. I knew he’d give me all the attention I wanted if we had the chance. But between work and family and everything else in life… Well, maybe there would be more time after Christmas. I could arrange an entirely free day where we could spend the whole time in bed.

My hair brushed so it wasn’t sex hair any more, I slipped the hairband off my wrist and tied it up into a ponytail. I didn’t usually like ponytails, because they didn’t suit my slim figure, but experience had taught me that loose hair and my nephews were not a good mixture. Satisfied with how I looked, I let myself out of the bathroom and headed downstairs.

“You okay, love?” Mum asked when she saw me. “Nathan said you were just freshening up a little.”

“Yeah, I was just feeling a bit tired,” I told her, blinking hard to try and sell it.

“Modern life is so hectic,” she said sympathetically. “I would say you could get an early night, but Christmas Eve never seems to end.”

“I’ll be fine. A couple of drinks and I’ll perk up with Christmas spirit.”

She laughed. “That’s my girl. If you want-“

The doorbell rang, interrupting her. Then it rang again, and then began ringing constantly, and then we heard raised voices outside.

“How would you like it if someone came and rang our doorbell constantly?” my brother Liam, the eldest, scolded his stepson Gavin, while his other child, Sam, kicked his trainers against the brick wall of the house.

“Hello everyone!” Mum said cheerfully, holding her arms out wide so the boys could charge over to her for a hug.

“Nanny!”

Kids stepmomentarily distracted, Liam took his chance to give me a tired smile and pull me into a hug. “Hi Sadie, nice to see you,” he said, leaning down to kiss my cheek.

“Hi Liam. Good trip?”

He laughed bitterly. “Usual chaos. Someone’s tablet didn’t get packed, so the first hour was a blazing row about whose turn it was to have the other one. Never have kids.”

I laughed nervously, trying not to think about Nathan on top of me twenty minutes ago.

Esther, my stepsister-in-law, was bringing bags from the car, dark circles under her eyes.

“Let me give you a hand,” I offered, rushing over.

“Oh, don’t bother. What’s the point of having men around if not to carry luggage?” she joked, giving me a quick hug, her arms still full. “Let’s get the kettle on instead. I think I’ll die if I don’t get some coffee in the next ten minutes.”

Liam and Nathan were dispatched to empty the car. Dad boiled the kettle and fussed around in the kitchen while Mum entertained the boys with that indefatigable energy that grandparents have for their grandchildren. I was lucky: Esther and I settled onto the sofa, catching up. We were a close family, especially the women, and when Liam had introduced us to Esther, it had taken us quite a while to warm to her. But she did her best and, most importantly, Liam adored her. She was more staid than our family were used to, but she was fun when she loosened up a bit.

“I am so glad to be here,” Esther said, lying her head back on the sofa cushion and sighing. “Travel with the kids is always so draining. I have no idea how I’d manage it without Liam; he has the magic touch with the boys.”

“Look who I found,” Liam said, sticking his head around the door into the living room, apparently summoned by the mention of his name.

“Hi!” my stepsister Tessa said, bursting into the room behind him. “We must’ve only been a minute or two behind you in the car.”

Esther and I got up to say hello, interrupted halfway through by Dad bringing hot drinks and then grumbling to himself as he went back to the kitchen to make more for Tessa and her husband, Adam, who came in a stepmoment later, carrying their four-year-old stepson Dan, who had some kind of chocolate all round his mouth.

“Let me hold him so you can find a cloth,” I offered, Dan grinning at me with chocolatey teeth.

“Thanks, Sadie. He’s a terror at the stepmoment, you can’t take your eyes off him,” Adam said, passing him over. My knees buckled under the weight of him.

“Wow, you’ve got bigger since I last saw you,” I commented, smiling at him.

“He’s like his dad: lanky and chunky,” Tessa said, shaking her head. In fact, amongst the entire family, it was only me that had got my mum’s petite gene. Dad was six feet and burly; Liam was made in exactly the same mould; and even Tessa was tall and curvy. On top of that, Esther was willowy and both Adam and Nathan were above average height, so it really was just me and mum against the rest of them, including the kids. Gavin was only nine and Sam eight, but in a year or two they’d be overtaking me.

Eight adults and three kids meant the house was completely overloaded. The three boys were sharing the attic room, because Gavin and Sam were Dan’s absolute heroes and he was inseparable from his cousins when they got together. Liam, Tessa and I were back in our childhood bedrooms, which were the only places you could get peace and quiet once the three boys got going. It turned out that Gavin’s current favourite toy was one of those plastic guns that shoots foam darts, so you couldn’t move all afternoon without being pelted with them. Eventually it was confiscated by Esther, who then secretly used it to pelt Liam whenever he let his guard down.

It was a relief, then, to help Mum and Tessa to make dinner in the kitchen, off-limits to all the noise.

“I bet all this means you can’t wait to have kids of your own,” Tessa joked to me as we stood side by side, peeling a huge bag of potatoes.

“Sadie and Nathan are waiting for the right time,” Mum said from across the kitchen. “Very sensible.”

I cleared my throat. “Um, actually… Nathan and I have started trying.”

Abandoning the potatoes, I turned around so that Mum could hug me.

“That’s wonderful, Sadie,” she said, dabbing at her eyes when she released me. “I’d love to see all my kids with kids of their own.”

Tessa smiled at me. “Not to take away from Sadie’s news, but, Adam and I are trying for number two at the stepmoment as well.”

This was emotional overload for Mum who, after more hugs and more tears, took herself off upstairs for a few quiet stepmoments to pull herself together. When she was gone, Tessa and I giggled.

“Poor Mum. Between all the weddings and children, she’s had a lot of proud stepmoments to deal with,” Tessa said, picking up a potato again.

“Good thing Dad keeps her grounded. Sometimes I wonder if Dad would even notice a new grandchild.”

Tessa laughed, and accidentally pushed the peeler too hard into the potato. The lump of peeling pinged up into the air and landed neatly in Tessa’s cleavage, making her gasp.

“That’s the problem with having giant knockers,” she grumbled, picking it out and flicking it into the sink. “They get in the way of everything.”

Ever since I’d been a teenager and it had become painfully obvious that my chest wasn’t going to develop beyond the smallest cup sizes, I’d envied Tessa’s tits. Admittedly, I’d always been able to wear whatever cute bras and bikinis I’d liked, whereas Tessa had to search ages to find anything that would fit. But Tessa’s bust attracted a lot of attention and I’d had to come to terms with being the objectively less hot stepsister. My jealousy about that had lessened when I’d met Nathan, who was one of the few men I’d gone out with who’d met Tessa and didn’t immediately have a look on his face like he’d chosen the wrong one.

Whichever way you looked at her, Tessa was gorgeous. Pretty, blonde, big boobs with long legs and a nice bum. Every father’s nightmare. Adam was a perstepsonal trainer and in great shape, and the mental image of the two of them having hot, baby-making sex was pushing all the right buttons in my horny imagination. I shook it off and focused on potatoes. Delicious, starchy potatoes. Fluffy, buttery… now I was hungry and horny. It was safe to say that being Tessa’s stepsister was very confusing at times.

Once Mum had collected herself enough to continue cooking, we managed to get dinner on the table for all eleven of us, everyone crowding in. Dad grumbled about constantly being elbowed on both sides, but Mum was in her element as hostess, handing around the dishes of vegetables and refilling glasses, then taking surreptitious candid photos of everyone on her phone but being completely given away by the sound of the shutter. Nathan and I sat at one end of the table, feeling slightly left out as the only childless couple, able to eat without the distraction of either encouraging our child to eat more (Dan) or encouraging them not to stuff so much into their mouth at once and then talk loudly and excitedly about cartoons (Gavin and Sam).

But we were quietly smug when, after dinner concluded, it was bedtime for the kids and their parents had to struggle to get them ready with just one bathroom. Not to mention the fact that having his cousins around made Dan get way overexcited and he wouldn’t calm down. The two of us just sipped our adult drinks and pretended not to hear the shouting upstairs.

“Are we doing the tradition and playing charades once the kids are asleep?” Mum asked, trying to sound relaxed about it, but there was a note in her voice which betrayed her excitement. “We could have four teams.”

“Um,” Nathan said, sounding guilty. “Actually, Liam, Adam and I were gonna do some gaming in the office. We don’t get many chances…”

I rolled my eyes. “Is blasting zombies more important than family time?”

“Sorta.”

He knew we wouldn’t object, since Liam had grown up with two girly stepsisters and having brothers-in-law who he could game with or play golf with was nice for him. And, hidden from my parents’ view, his fingers were wandering up the inside of my thigh, which he knew was a weakness of mine. I squeezed my legs together, trapping his hand before he could get too far up, because knowing how horny I was feeling, I didn’t trust myself not to let him finger me right there in the living room.

“Well, that leaves five of us, which is awkward for making teams…” Mum said, uncertainly.

“We can just play as one big team,” I assured her.

Nathan continued to tease my waist and my hips, just where my t-shirt met my jeans and exposed an inch of skin, not going too far but doing enough to keep me on edge. Dad started yelling for Mum from the kitchen, some incomprehensible question about food, and once she’d huffed and gone off to see what he wanted, we had the room to ourselves, somehow. When I oh-so-accidentally brushed my hand across his lap, I could feel that his cock was getting hard, so I took advantage of a quiet stepmoment to whisper in his ear.

“Have fun playing games with that thing in your pants,” I giggled.

“You know if we were at home I’d be playing a very different game,” he replied, letting his hand drop down to the top of my arse.

“As soon as we go to bed I want to feel it inside me again,” I told him, my voice dripping sex, and he squeezed his eyes shut and groaned. I hoped he’d find it hard to concentrate for the rest of the evening with that prospect before him.

By nine o’clock, at last, the kids were all safely in bed, two floors away, and the three gamers departed to Dad’s office, where the big TV was, with a six-pack of beer. Esther looked shattered when she collapsed down into an armchair, but Mum didn’t want to miss out on the tradition.

“You get everything set up. I’m listening,” Esther said, opening one eye.

“We’ll keep it simple,” Tessa said, entering bossy big-stepsister mode. She always liked to run the game and keep track of the score, not so much because she was competitive but more because she liked to be in charge. “When it’s your turn, take a card and act out whatever’s written on it. They’re all different types of jobs in this round.”

“And how do we win?” Dad asked wearily.

“If you guess it first, you get one point. If you’re doing the acting and nobody gets it in thirty seconds, you lose a point. Any questions?”

“Who’s going first?” I asked, looking at her over the rim of my wine glass. I was either on my third or my fourth glass, I wasn’t sure.

“I am,” Tessa said, not allowing anyone else a look in.

Family charades always sounded stupid when it was suggested, but once people got into it, it was fun. Tessa was a ‘marine biologist’ to start off, which nobody got, and she began the game on minus one point. Mum was a firefighter, which was an easy one to guess, and Dad did his best to sabotage being a taxi driver by making it look more like a racing driver, but Tessa was quick enough to get it. Esther’s perfect cobra position made ‘yoga instructor’ easy, and I mimed scoring a penalty kick so Mum could correctly guess ‘football player’. My over-the-top goal celebration made everyone laugh, and from that point on the game was less about accurate acting and more about amusing the audience.

“Snake charmer!” Mum yelled in a fit of excitement, and Esther, sitting cross-legged on the floor, shook her head and then shushed her.

“Snake charmer? How does that look anything like a-” Tessa said, but Dad interrupted.

“I know, it’s those, you know, um… hippy things. Bongo player.”

“That guess was worse than Mum’s,” I told him, and he made a face at me.

“Time’s up,” Tessa announced.

“I’m supposed to be a teacher. I was reading a book to everyone,” Esther said, miffed.

“Why didn’t you pretend to use a blackboard?” Mum asked, giggling.

“What teacher uses a blackboard these days?”

“It’s not about being a modern teacher, you just need to convey the essence of a teacher,” Tessa told her.

“Essence of a teacher? What the hell is that?”

I took the next card and stared at it, shocked.

Lap dancer

“Um, I don’t even… Can I put it back?”

“No way, I didn’t put back marine biologist. It can’t be worse than that,” Tessa said firmly.

“It is, in a way.”

“Don’t care. My game, my rules.”

“Who said it was your game?”

“I did.”

“Girls, don’t fight. Sadie, I’m sure it’s not that bad,” Mum said, trying to smooth things over. “Just try it out.”

I thought about it. If I just gyrated around nobody would ever guess it: having someone’s lap was essential to the job. But by process of elimination, since I was absolutely not going to grind on my mum or my dad, and as fun as Esther was, she was still my stepsister-in-law, it had to be Tessa’s.

“Okay, time starts now.”

Not wasting a second, I dashed over to my big stepsister, who was sitting curled up sideways on the sofa. Despite her protests, I grabbed her ankles and dragged her into a proper sitting position, her legs spread apart. Luckily she was wearing leggings and not a skirt or anything. When she was ready, I turned myself around to face away from her and sat myself down, wiggling around wildly, rubbing my bum all over her thighs.

Esther stared, torn between shock and wanting to answer. “A stripper!”

“Sadie!” Mum said, pretending to be outraged.

But I shook my head. Tessa would check the card after my turn and since the words ‘lap-dancer’ and ‘stripper’ weren’t exactly the same, even though anyone would think they were synonymous, she’d say I’d broken the rules.

“Not a stripper?” Esther asked, confused, as I turned around and sat myself on Tessa’s knee.

“It’s definitely a stripper,” Tessa said as I put my hands on her shoulders and rubbed my pussy on her leg through my jeans, her boobs bouncing slightly from the movement.

“I’ve got it,” Dad announced, and I breathed a sigh of relief. “Exotic dancer.”

I shook my head firmly, and pointed insistently at Tessa’s lap.

“Is pointing allowed in the rules?” Esther asked, giving me an evil look. I glared back.

“If it’s not stripper, I have no idea,” Tessa said, and I figured I might as well go all-out. Turning away from her again, I plonked my bum right down on her lap, arched my back and rubbed back and forth for all I was worth. She put her hands on my waist to steady me.

“Lap dancer.”

“Finally!” I said, triumphantly, getting up like a scalded cat. But when I turned around, I saw Nathan and Adam in the doorway, grinning like maniacs, and realised it was Nathan’s voice I’d heard.

“And what would you know about lap dancers?” Tessa teased him, making everyone laugh.

“Only what Sadie’s told me,” he replied, giving me a cheeky look.

“Sadie! I would never have guessed,” Mum said, outraged again.

“Anyway, that means I don’t lose a point,” I insisted, trying to move the conversation on.

“Yes you do: none of us players guessed it,” Tessa responded. “That’s the rule.”

“No way. If Nathan hadn’t guessed it, someone else might have.”

“Sorry, Sadie, I don’t think any of us would have got it,” Esther said, and Tessa had great pleasure in deducting one point from my score.

“Sorry, babe,” Nathan said, not sounding sorry. “We’re just grabbing more beer. Anyone want anything?”

Nathan was still hanging out with Adam and Liam when I decided to call it a night, the wine going straight to my head as I climbed the stairs, trying to keep the noise down so I wouldn’t wake the kids. Another perk of being childless (so far) was that I didn’t need to sort out all the presents from Father Christmas, which Esther still had to drag up to the attic room before she could go to sleep. The alcohol had made me sleepy and I only managed to undress as far as my knickers and t-shirt, taking off my jeans and bra and leaving them strewn across the floor like in the good old days.

The next thing I knew was when Nathan got into bed, filling the room with the aroma of beer and jostling me awake.

“Sorry,” he whispered, putting an arm around me as he laid down in the bed beside me.

“S’okay,” I murmured sleepily, pushing myself up against him. I didn’t mean anything by it, wanting more than anything to fall back to sleep, but I should have guessed that his cock would be hard, given the suggestion I’d made to him earlier. He pushed it firmly up against my arse and his hand slid over my tummy, lifting my t-shirt until his fingers were brushing the bottom of my tits.

“Did gaming turn you on this much?” I asked, wiggling my bum against his cock and managing a smile.

Nathan laughed dryly. “You know what caused this.”

I played innocent. “I have no idea.”

“Yes you do.”

“Hmm… no, I don’t think I do.”

He chuckled, knowing when he was being teased. “So we’re not going to talk about what happened earlier, then?”

I smiled to myself, knowing that he remembered my proposition. “No idea what you mean,” I said, keeping up the act.

His hand slid to my hip and he held tightly, grinding his cock against me until I let out a soft moan.

“You don’t remember what I walked in on?” he asked, slightly breathless.

I froze. I’d assumed we were still talking about me telling him I wanted to feel his cock inside me earlier, but now I had to think rapidly about what it was he was talking about.

“Huh?”

Luckily, he thought this was part of the game, and kissed my neck as he rubbed his cock on my arse rhythmically.

“You giving Tessa a lap dance.”

“Oh.” The reastepson this hadn’t come immediately to mind was because I didn’t realise it was a ‘sexy’ thing: I’d just been trying to win at the game. I’d thought I looked ridiculous, honestly. But Nathan’s cock was really hard up against me and I didn’t want to ruin his stepmoment here.

“Did it turn you on…?” I asked, trying to gauge which direction this was going.

“Fuck, yes,” he confirmed, pushing into me harder and digging his fingers into my hip.

“Did you like seeing me pretending to be a lap dancer?”

“Definitely.”

Okay, this was working for me too. I could feel myself starting to get properly aroused and I squeezed one of my nipples between my fingers through the fabric of my shirt, biting back a moan.

“Grinding myself all over someone…”

He kissed my neck again. “All over another girl,” he corrected.

I giggled. “You want me to be a lesbian lap dancer?”

“Absolutely. That’s the best kind.” His breath was a little ragged, betraying how much he was enjoying this, and I couldn’t help but burst his bubble a little bit.

“You know that other girl was my stepsister, right?” I said, ready to feel him squirm.

His hand slid from my hip across and between my legs, lifting one of them so he could rub my clit through my knickers. “That works for me,” he said, a lot more confidently than I’d expected.

I think I would have been more freaked out if I wasn’t still a little drunk, but the touch of his fingers firmly on my clit and his hard cock up against my arse meant I wasn’t doing much straight thinking. In any sense of the word.

“You want to see me and Tessa together?” I asked, half-moaning, my heart racing.

“A man can dream, right?”

Fuck. My imagination was starting to go in a very forbidden direction which involved Tessa in fewer clothes, then no clothes, then…

I pushed Nathan’s hand away from my clit and rolled over to face him, kissing him hard, my arms grabbing him tightly and pulling him close. He grabbed me back, kissing quickly, responding, and any naughty thoughts in my head about naked lap dances were replaced with thoughts of Nathan and how hot he was, and his big, throbbing cock which was all mine to play with.

“Do you want to open your present?” Nathan asked breathlessly, breaking our kiss.

“Present?”

“I got something normal for you to open tomorrow, of course, but since it’s technically Christmas Day now… I got something kinky too.”

I grinned at him. “Kinky sounds very fun.”

Rolling off him, I lay on my back and watched the dark outline of him moving around the room to his suitcase, then rustling inside until he had a plastic bag in his hands.

“Happy Christmas, babe,” he said, climbing back onto the bed and giving it to me, his cock bouncing inside his underwear, still hard. I really wanted to touch it and hear him react, but the present was more important.

In the dim light it was hard to make out what they were, but after exploring them with my fingers for a minute and getting my fingertip stuck inside I realised.

“Nipple clamps… you really did mean kinky,” I giggled.

“Want to put them on?”

Up until he said it I hadn’t actually realised that they would go on my nipples. I felt a delicious rush of anticipation go right through me. “Mm, yes I do,” I told him, reaching down to my waist and pulling my t-shirt over my head, then kicking off my knickers too.

I stayed lying on my back, head on the pillow to get comfortable, while Nathan propped himself up, fiddling with the clamps for a second. Then I felt his hand slide onto my tummy and upwards, his thumb skimming across my breasts, finding my nipples which were already hard and sticking out firmly.

“Mm,” he said, appreciatively, giving one a squeeze, and my breath caught. My nipples were incredibly sensitive, and just the touch of his hands was enough to make me think I’d reached my limit. Then he closed the jaw of one of the clamps onto me and I had to grab the sheets with both hands, kicking my legs and forcing my mouth to stay closed so I wouldn’t moan out loud.

“Oh fuck, that’s so intense,” I said when I could form words again. The pain had felt unbearable as it had built, but now it had transformed into a kind of knife-edge pleasure, where the slightest movement of the clamp would both hurt and enhance the pleasure even more.

“You want the other one, too?” Nathan checked.

“Mm hmm. Just do it. I can handle-“

But in that stepmoment he attached the second clamp and I had to bite down on my fist, clawing at the bed with my other hand.

There was a fine chain connecting the two clamps together, and Nathan gave it an experimental tug. I moaned immediately, squeezing my legs together and my mind going utterly blank except for the two points of pleasure racing through me.

“Good?” he asked.

“Fucking amazing.”

With that, his hand slipped down between my legs, easing my tense thighs apart and finding my pussy.

“Fuck, you’re so wet,” he gasped, but I could barely reply as the additional sensations from my clit mingled with the sharp shafts of pain from my nipples. I just rolled my hips to encourage him, my eyes tightly shut, and he slowly went from rubbing my clit to pushing a finger inside me, adding a second, and pushing them hard against me in opposition to the pressure on my clit. It felt really good right up until he gave the chain a soft tug again, and then it felt beyond incredible.

Nathan recognised how good this was for me and didn’t go crazy; between fingering me and stimulating my nipples, I was moaning into my hand and tensing all over. This was the release I’d wanted for weeks and now it was rushing towards me unstoppably. I drew in huge breaths of air, needing it to keep myself from screaming, and then my body curled inwards as I came on his fingers.

“Fuck,” I said, the word sharp and stabbing through the quiet bedroom. I’d expected to come down from my orgasm, but with the relentless pressure on my nipples and Nathan’s hand between my legs, the pleasure didn’t diminish. My moans returned and I writhed on the bed, both wanting him to stop but also not wanting this to ever stop. It was like being on a rollercoaster that only went downwards.

“Nathan… fuck… I’m…” I said, trying to form the words to ask him to be more gentle, but they wouldn’t come and he did the opposite, pulling on the chain properly and firmly. The clamps pulled hard on my nipples and the shock of it made me moan out loud, too loud, and Nathan’s slight intake of breath meant he realised he’d done too much. But that pull hadn’t just tipped me over the edge, it had grabbed me and thrown me over the edge. I was in freefall, orgasming again, my legs tensing and then relaxing and then tensing again, almost shaking, his hand the one constant point of pressure against me.

“Oh… fuck,” I said through gritted teeth, unsure if I was having two orgasms from this or just one long one. Either way, I couldn’t remember the last time I’d felt this good. I could barely remember my own name. It was so perfect after our long spell of rushed sex.

And then the comedown did hit me and I began breathing heavily, shaking through weakness now, and I gingerly unclipped the clamps from my nipples, breathing through the pain and feeling relief course through me. Nathan withdrew, kissing me gently on the shoulder and collarbone.

“Good present?” he breathed.

“Amazing,” I giggled, kissing him on the lips. “Fuck, why didn’t I know about these years ago?”

He laughed. “You can use them as much as you want from now on.”

Just the thought felt too intense. “I really will. Now I need you to fuck me.”

He got up out of bed eagerly to take his underwear off and I wondered if I would ever have enough energy to lift my body again. In the quietness as I watched him undress, a gentle thudding became apparent, and my brow wrinkled.

“Is that music?” I asked Nathan in a whisper.

“You reckon it’s the kids playing silly buggers?” he replied, glancing up at the ceiling.

“Their room is over Mum and Dad’s, they’d get caught in an instant,” I said, still hearing the thudding. It sped up a little, and Nathan traced the noise to the wall, not the ceiling.

“It could be music… a car outside?” he suggested, but then a very feminine, very sexual moan came through the wall and we looked at each other.

“Oh,” I said.

Nathan grinned at me. “Sounds like Tessa’s enjoying herself, at least.”

Judging by the pace of the thuds, Adam was putting his muscles to good use and she was getting a really good fucking. Just the thought was making my cheeks get flushed. There was another moan, then the low rumble of a male voice and some laughter, then the moans stopped, the thuds reducing in intensity but not stopping altogether.

“Do you still want to…?” Nathan asked, his hard cock making it obvious he did still want to.

“Yes.”

As he climbed back into bed next to me, my body still tingling from the orgasms, fighting the tiredness with a fresh wave of sexually-induced energy, I tried not to think about the thudding. But I didn’t know whether it was because the thought of Adam and Tessa fucking on the other side of the wall was a turn-off, or because it actually turned me on and I was refusing to admit that to myself. They were a good-looking couple and it made sense that the two of them having sex would be exciting. But it was my big stepsister, the same one who’d hide my things or tell lies about me to Mum and Dad or, worst of all, take absolutely forever to use the bathroom when I wanted it. It wasn’t normal to think about her lying on her back, legs spread as her husband fucked her. Or maybe she was on all fours, tits swaying underneath her as he pounded her from behind, his hand over her mouth to stop her moaning, her head tipped back, ready to-

“Where do you want me?” Nathan asked, interrupting my thoughts. I blushed, which he luckily couldn’t see in the dark, realising I’d got carried away.

“On top; I’m not sure I can lift myself after earlier,” I told him, and then he carefully aligned himself above me, my legs parting, wrapping around his waist as he used his hand to rub his cock over my pussy, getting into the right position. I pushed my heels into him to encourage him when he’d found the perfect spot, and then I let out a low hiss as his cock finally filled me, sliding in easily from how wet he’d got me earlier.

“Fuck, Sadie,” Nathan groaned, resting his weight on his arms so he could start fucking me, which felt amazing. Not as world-shattering as the feelings from a few minutes ago, but nothing beat the intimacy of being fucked by Nathan. I loved the noises he made and the way he touched me, now bending down to kiss my head, now taking steady, athletic breaths so he could fuck me more consistently. He was great in bed and knew just how I liked it.

“Cum inside me,” I whispered, stating the obvious but feeling him nodding in response. We had to keep the noise down. Tessa and Adam had proven that any noise, even the noise of the bed, was too much. I had no idea if they were still going, but I was finding it impossible to get the image out of my head. Tessa riding him, his hands grabbing her big tits to stop them bouncing, moans escaping her as his cock pushed hard and deep into her…

Forcing myself to stop thinking about it, I tried to exist in the stepmoment. The sensations of Nathan inside me. His body on top of me. The hard breaths I was drawing, my nipples moving up and down on my chest, still tender from earlier. Would Tessa use nipple clamps? Her boobs would look incredible like that, nipples squeezed firmly, biting her lip to fight the pain, reaching down and touching herself…

Okay, enough was enough. When I found myself fantasising about people who were off-limits, I played a game in my head to put me off them: I imagined a bad date with them. For example, when I’d run into one of my hot ex-teachers in a pub a few years ago and he’d given me his number, I’d wondered about whether I could fuck him. But then I imagined the date: sitting in a restaurant, trying not to think about how much older than me he looked. What other people there were thinking. Then what would happen afterwards? Back to his place? But his wife would be there. Maybe he had kids. And by this point, I was so thoroughly put off this guy that I couldn’t even think about him sexually, and his number got deleted.

So while Nathan fucked me, I employed this technique. A restaurant, way too busy, food taking ages to arrive. We had wine, but it didn’t taste nice and didn’t match the food. Me in my tight-fitting black dress with the short sleeves, neckline plunging down between my tits, the skirt tucked under my bum as I sat, nails painted black to match. Too dressed-up for the situation and feeling self-conscious Opposite me: Tessa, sipping her wine, making a face. Wearing a light blue, high-necked dress, her tits fully covered but still very obvious. A long slit up her thigh, almost to her hip. A belt around her waist to accentuate her figure, and a sequence of bracelets on her arm glittering as she lifted the glass. She looked fantastic, even on a bad date. People noticing us, two stepsisters having dinner, our hands occasionally brushing against each other’s, laughing about old times. Not knowing about the heat below the surface; the way Tessa’s eyes were exploring my cleavage, the way I tried to catch a glimpse of her long expanse of exposed thigh. The occasional stepmoment of eye contact, my cheeks reddening, Tessa playing with her hair.

Then back to her house, sitting on the sofa with wine, teasing each other, still in our dresses, until one of us couldn’t take it for a stepmoment longer and leant over to kiss… And then dresses would come off, her boobs falling out of her bra as I unclasped it, her hands exploring all over my back and my neck and my hips as I lay on top of her, kissing frantically, her nipples pushing into me, bringing her thigh up between my legs until I was grinding against it, wetter than I’d ever been. Up to the bedroom, falling onto the bed, still kissing, her lips on my neck, my nipples, my arms and my tummy and then finally…

My eyes flicked open and I looked at the ceiling, partially obscured by Nathan’s shoulder. Fuck. The bad date had turned into a good one. Maybe I did fancy Tessa. Why did fantasising about her feel so easy and not weird at all? It almost felt natural. Who better to show me what it was like to fuck a girl than my big stepsister? Was I bisexual if I wanted to have lesbian sex with her, or was I just attracted by the thrill of the forbidden? So many questions kept bobbing to the surface before sinking again. But the fantasy date had made one thing completely clear in my mind: if Tessa was into it, I would have a very hard time saying no. Even if she was my stepsister.

“I’m pretty sure they’ve stopped next door,” Nathan whispered to me in between thrusts. “Can’t hear anything now.”

“Okay,” I said, holding him more tightly, roused from my thoughts. “She told me earlier that she and Adam are trying for baby number two at the stepmoment.”

“Really?” Nathan paused his movements for a stepmoment. “Aw, that’s so nice. A little brother or stepsister for Dan.”

“Stay focused,” I told him, tapping his cheek gently to get him to resume fucking me.

“Sorry.” He found his rhythm again.

I’d thought that my orgasms earlier would have made me less horny, but there really was nothing like being fucked to switch off the rational circuits in my brain. “If they’ve stopped, it’s probably because he’s cum inside her.”

Nathan remained completely silent, but the way his cock pulsed in response to what I said made it very obvious that it had turned him on. I knew him, and he was just staying quiet out of respect for me and not wanting to admit to thinking about someone else during sex. But I wasn’t in the mood to be respectful Sadie: I wanted to be dirty, disrespectful Sadie.

“They were probably in the same position as we are, him lying on top of her, her big tits pushing into him…”

“Fucking hell, Sadie.”

“Are you thinking about them fucking?”

“Well, I am now, yeah.”

“Me too.”

“Fuck…”

“She was probably begging him to cum inside her, wanting to feel him explode as he went in and out, in and out, in and out…” I timed what I was saying with Nathan’s thrusts, and I felt his body shake slightly, a sure sign he was getting close. Fuck, this was so much fun. And turning me on so much.

“Nathan?” I asked, my voice soft and sensual.

“Yes?” He was hoarse, breathing heavily.

“Do you want to fuck my stepsister?”

“Sadie, what am I supposed-“

“Tell me.”

“I, uh, it’s-“

“I’m okay with it. I want to watch you with her. I want to watch you fucking her tight, sexy pussy and playing with her amazing tits, making her moan.”

“Fuck, fuck, fuck.”

“So do you want to fuck my stepsister?”

“Fuck… yes.”

“Yes?”

“Yes I do want to fuck her.”

I moaned gently, gripping him, those words turning me on beyond anything I thought possible. “Then do it. Imagine you’re fucking her right now.”

“I… fuck, that’s so hot, you’re so hot.”

“That’s it. Fuck her pussy hard, just how she likes it.”

“Fucking hell… Sadie, this-“

I reached up and pressed my finger to his lips. “No, not Sadie. Call me by my name.”

“Sadie-“

“No. My name.”

“Fuck… Tessa.”

It was like jolts of electricity were running all over my body. Hearing him say her name was a high I’d never experienced before.

“Yes, fuck me. Fuck me, Nathan.”

“Oh fuck… Tessa, yes. Take it.”

“Fuck me. Fuck your wife’s stepsister.”

“Oh yes, oh fuck.” He was beginning to lose control and I loved it.

“Cum inside me.”

“Fuck.”

“Get me pregnant.”

“Fuck.”

“Put a baby in my sexy body, get me pregnant just like you’re going to get my stepsister Sadie pregnant.”

He pounded his cock into me over and over as he came, his fingers digging into my shoulders as he gasped, holding back his groans of pleasure. I used my feet to hold him in place, buried deep inside me, taking all of his hot cum. I’d thought the nipple clamps had taken me to a level of pleasure I’d never experienced but this was something even more intense.

When he finally lifted his body up, his cock withdrawing from me, panting, looking at me, I just sat up and kissed him, quickly.

“Need to go and clean up,” I said, pushing my legs off the bed and searching for my knickers.

“Sadie… what just happened?”

I giggled, pulled my knickers up and looked at him. “Did it turn you on?”

“Well, yeah, but-“

“It really turned me on as well. What else matters?”

He considered this. “Okay,” he said, lying down heavily on the bed. “If you’re sure, I mean.”

“I am. Back in a few minutes.”

With that, I pulled on my t-shirt and went out of the door, checking there was nobody around, feeling Nathan’s cum quite definitely leaking out into my knickers. I’d clean them up when I got to the bathroom, which was mercifully only a few steps to my right and-

Occupied.

It was like childhood trauma brought straight back to life. Except this time, it wasn’t stopping me from putting on makeup before school, it was stopping me from preventing my husband’s cum ruining my knickers.

Biting the bullet, I knocked gently.

“Sorry, won’t be a minute,” Tessa replied from inside.

“It’s Sadie. I really need to use the bathroom. It’s urgent.”

I could definitely feel some cum making its way down my thigh. Carpet stains would be a disaster.

“Really urgent.”

I heard the lock slide back and Tessa’s face appeared in the light when she opened the door.

“Come in for a second.”

Gratefully, I slipped through the gap in the door. If the worst happened, bathroom tiles were much easier to clean. She closed it behind us and put the lock across again, and we looked at each other.

I was wearing a t-shirt with my nipples poking through the fabric, still hard from fucking Nathan a few minutes ago. My hand was between my legs, cupped to try and stop his cum from sliding any further down out of my knickers.

She was wearing a t-shirt with her nipples poking through the fabric. Her hand was between her legs, and the sticky liquid glistening on her skin down there suggested that she had exactly the same problem I did.

We both saw the funny side and giggled uncontrollably.

“This is why we shouldn’t try to conceive at Mum and Dad’s,” Tessa said, shaking her head.

“Or in a house with eight adults in it and one bathroom,” I pointed out.

“They should have put a second one in years ago.”

“I know, exactly.”

Tessa took a breath to steady herself, then glanced down at my thighs again. “Okay, I really need a shower to… get all this off me. Can you wait a few minutes while I do that?”

I nodded. “I think so. The worst is over, probably, and I can use the sink.”

“You can have the shower after me if you want.” She reached into the shower and switched it on, the noise of the water running sounding very loud in the quiet house. I shuffled around and perched on the edge of the bath, watching as Tessa turned her back and used her free hand to pull her t-shirt over her head, then edged her knickers over her hips and bent forwards to carefully step out of them. Her pussy was a little swollen and red, doubtless from the sex she’d just had, and I could clearly see Adam’s cum all around it. For a split second I felt an intense desire to step forwards and touch her there, feeling the sticky wetness, eliciting a moan from her as my fingers found her slick clit. But it subsided just as quickly as it had come, and she climbed into the shower a stepmoment later. I was clearly still worked up and horny.

“So I take it you’re ovulating?” Tessa asked, hidden from view by the shower curtain.

“Yeah, I’m pretty sure. We’ve only been trying for a couple of months so I’m still getting used to my cycles.”

“It took us nearly six months to get pregnant the first time, so don’t worry. There’s a lot of trial and error.”

“Do you feel really… you know, ‘in the mood’ when you’re ovulating, or is it just me?” I asked, a little nervous.

Tessa laughed. “Oh my God, absolutely. It’s like, no amount of sex is enough, I could go for fucking days. Right now I am still soaking wet down there.”

I giggled. “I’m the same. Last month I had to sit there at work pretending I wasn’t a huge horny mess the entire time.”

“Last time we were trying, one day I had to tell work I was sick and leave at lunchtime. I made Adam go home too and we spent the rest of the day screwing. I thought I would go insane otherwise.”

“I feel like I’m touching myself three times a day to try to keep it under control.”

“Tell me about it. My hands are barely off my clit. And, worst of all, I forgot to pack my vibrator for this trip, so it’ll be torture.”

I laughed at the frustration in her voice, and then my eyes alighted on my makeup bag.

“Um, I did bring mine, so if you wanted…”

Tessa turned the shower off and put her head around the curtain, keeping her body covered.

“Are you serious?” she asked, fixing me with a look.

“I mean, I want it back, obviously, but if it would help you out I don’t mind sharing. It’s in my makeup bag if you want it.”

“You are the best stepsister in the world, Sadie,” she grinned. “Pass me a towel.”

As we swapped positions, Tessa using a towel to dry herself while I undressed, I noticed her eyes lingering over my cum-soaked pussy just as I’d looked at her earlier. I supposed it wasn’t every day you got to see what someone else looked like after they’d been fucked and filled with cum, and I tried not to read too much into it. By contrast, as she used the towel, I found it hard not to stare at her boobs, which looked incredibly big and pillowy. She dried underneath them by lifting them up, not something I had ever had to do with mine, and it intrigued me so much that she laughed.

“It’s amazing how different we are even though we’re stepsisters,” she giggled, pushing her tits together to make her point. “Are we sure Mum wasn’t seeing the milkman at one point?”

I averted my eyes, climbing into the shower, my nipples still hard and probably not just from Nathan any more. “We look too much alike,” I replied. “It’s like, from the tops of our heads to our necks, we’re definitely stepsisters. Below that, it’s a total mystery.”

“Mm, that’s true.”

I focused on actually cleaning myself for a bit and let Tessa get dry.

“I’m, um, just going in your makeup bag,” she said, sounding embarrassed.

I laughed, turning around in the shower so it could spray my back. “Go ahead. Just put it back when you’re finished.”

“I will. See you in the morning, Sadie.”

She couldn’t lock the door behind her, so I had to get out of the shower and do it myself. I was just in time to see her go, wet knickers in one hand, my electric blue vibrator in the other.

Without her to distract me, I was able to clean up, dry myself and open the bathroom window to let the steam clear. It was chilly outside and I grabbed my shirt quickly, tugging it down around my hips. It wasn’t long enough to completely cover my bum, so it would need to be a quick dash back to the bedroom, knickers in hand.

Carefully exiting the bathroom, I covered the few paces back to my bedroom door, then paused to open it slowly and quietly, not wanting to disturb anyone’s sleep. As I did, I heard another door opening and my heart shot into my mouth. I was hoping it was Tessa again, but before I could edge back into my bedroom, I looked around and saw Mum coming towards the bathroom.

As we looked at each other for a stepmoment, she seemed as surprised to see me as I was to see her. Mum was wearing the shirt that Dad had been wearing the previous evening, loosely buttoned, and her hair was a complete mess. As she got nearer, I realised her décolletage was wet with something and I tried not to think about what. Plus there was a blob of it in her hair.

“Let’s keep this to ourselves?” she suggested in a low whisper, and I nodded vigorously.

She giggled to herself, exactly like a woman who had just had a fun sex session, and kept going to the bathroom as I went back into the bedroom. Nathan was sound asleep and still naked in the bed when I climbed in beside him, and he sleepily put his arm around me as I cuddled up close to him. I wanted to say something cute and romantic to him, but I was more tired than I thought and I was asleep before I could think of anything.

Morning came far, far too early. The boys were up just after six, waking the rest of the house up as they excitedly tore into their presents, and after a conference with Liam, they agreed to at least not go downstairs until eight. I listened to this going on, muffled by the floorboards, slowly having the realisation that I was hungover. After another hour or so of fitful sleep, not helped by Nathan snoring solidly away next to me, I gave up, got dressed and went downstairs.

“Is this new?” Mum asked me, looking at my Christmas jumper, any embarrassment from the night before completely gone. I could tell she’d washed her hair, though.

“Got it in my work Secret Santa,” I explained, looking down at the reindeer riding a toboggan across my chest.

“It’s cute. I like it.”

Even though Mum was busy getting breakfast ready, followed immediately by starting to cook lunch, the kitchen was a refuge from the chaos outside. Opening presents for an hour was enjoyable, especially with the kids around going crazy, and seeing them gasping at everything they opened and jumping up and down with excitement only made me want one of my own more. But once the batteries had been inserted and the flashing lights, electronic bleeps and wailing sirens had started, the kitchen was a much quieter and calmer place to hang out. And, most importantly for my hangover, it had coffee.

When I went upstairs to clean my teeth and put on a bit of makeup so I’d look presentable for the rest of the day, I realised that my vibrator had been carefully replaced in my bag. I badly wanted to grab it and spend an hour in bed working off my sexual energy, but there was no chance of any privacy with kids and adults running up and down the stairs and food on the way. So I had to pretend I hadn’t seen it and focus on my makeup.

Back in the kitchen, Mum had disappeared somewhere, but Tessa was there, doing a quick bit of washing-up to be helpful. Somehow she had managed to pull off a cute-but-sexy look today; long hair falling down her back, her jumper was patterned in a somewhat less ugly manner than everyone else’s, and her feet were tucked into big fluffy slippers, but as she leant forwards over the sink the curve of her bum was snugly encased in thermal leggings, which also showed off her hips and thighs to best effect. For about the thousandth time in my life I envied her, trying not to think about my skinny legs.

“Did you get to bed okay last night?” she asked, keeping her voice down, looking over her shoulder at me.

“I did. Thanks for returning… you know what.”

She smiled. “It really helped me to relax.”

I walked over and dropped my voice to a whisper. “When I went back to our room, I bumped into Mum coming out of her room.”

Tessa looked intrigued and raised an eyebrow. “And she knew what you’d been up to?”

“More like I knew what she’d been up to.”

My big stepsister giggled. “Oh God, embarrassing. So all three of us girls were getting some sugar last night.”

I couldn’t help but laugh. “Seems like it. Must have been the Christmas magic in the air.”

“I wonder whether Esther and-“

“Don’t say it,” I said, my shoulders shaking with suppressed laughs. “Your mind is so dirty.”

“You know what Liam’s reputation is, anyway,” she said casually, and I shook my head.

Liam didn’t have a reputation. What had happened was that a girl Tessa knew had briefly dated him (I’m not sure it was much more than a one night stand) and claimed that he was both ‘amazing in bed’ and ‘had a really big cock’, neither of which we could confirm. But we’d heard this when we were both still quite impressionable about boys and sex, and ever since Liam had enjoyed a sort of legendary status with us. It helped that he’d met, and married, Esther not long afterwards, a girl he himself admitted was out of his league. He had always been protective of his little stepsisters and both of us, at some point, had harboured a kind of puppy-love crush on him.

“That was years ago, Tessa,” I replied, dismissively.

“Oh, come on, Sadie. Don’t you think it’s fun that all four couples in the house might have been fucking at the same time?”

“Tessa!”

She grinned naughtily. “In nine months we might have four little babies!”

“You did not just say that.”

“What? It’s a possibility.”

“I think Mum’s days of pregnancy are over.”

“Good point.”

“And anyway, you can’t get pregnant from what Dad had done to Mum’s boobs.”

Tessa’s mouth dropped open and I giggled, pleased to have scandalised her for a change, and then Mum walked back in, carrying a box of soft drinks.

“What’s so funny?” she asked, looking miffed to have missed out on a joke.

“Inside joke between stepsisters,” Tessa said, giving me a meaningful look.

Since they’d been up early, after lunch the boys were sent back upstairs to nap for a couple of hours, giving the adults some peace and quiet. After Esther had settled them down, I was volunteered to go and check on them fifteen minutes later to make sure they were definitely asleep, which meant dragging myself up two flights of stairs and stealthily creeping into their room.

“Excuse me,” I hissed at Sam, who was lying under his blanket, some kind of electronic device lighting up his face. “I’m pretty sure you’re supposed to be sleeping.”

He looked embarrassed. “Sorry Auntie Sadie,” he said, but I noticed him slipping the phone under his pillow for future use.

“No no, you give it to me and you can have it back later,” I demanded, holding my hand out.

Clearly he knew that if he disturbed the other two, who were asleep, he’d get into trouble, so he just handed it straight over, the screen lit up with a block-matching game he’d been playing.

“Get some sleep,” I said, turning and heading for the door as he pulled the blanket back over himself, lying down properly this time.

I paused outside their bedroom door for a few minutes, listening out for anything else that shouldn’t be going on. The phone I recognised as being Adam’s: it had a sticker on the back of the rubber case with the phone number of the gym he worked at. I had no idea how Sam had come to have Adam’s phone, but clearly he’d worked out it had some fun games on it. I closed the game itself, then opened the photo gallery. Adam had taken some group pictures of us all during lunch, actual good ones unlike the blurry candids Mum always took, and promised to send them to me, so I thought that while I waited for Sam to fall asleep, I might as well save him the job.

Most of the other photos on his phone were selfies he’d taken in the gym in some kind of bodybuilder pose, and as I scrolled through, idly curious, I wondered how many photos of himself he could possibly need, especially as they were nearly all identical. Then, in the middle of them all, there was a video with a dark background and what looked like Tessa’s hair in the thumbnail. I knew before I pressed it that I absolutely shouldn’t look at it, but curiosity got the better of me.

“Are you recording?” Tessa asked, tossing her hair out of her face, the camera too close to her, getting unflattering angles of her cheekbones.

“I am now,” Adam replied, off-camera.

Now he sat back and I had to suppress a gasp as Tessa came into focus, completely naked and straddling Adam, her tits bouncing slightly in the low lamplight of their bedroom. She rolled her hips for a stepmoment, making Adam grunt as his cock went in and out of her, and she giggled before looking at the camera. I paused the video and dashed off to my bedroom, still knowing I really shouldn’t be watching this, especially because it was clearly a sex tape of Tessa. But I was far, far too horny to stop now.

Page 4

“Hi Nicole,” she said, unexpectedly, lifting one hand and waving at the camera. “I’m Tessa, Adam’s wife, and I know you have been flirting with him in your perstepsonal training sessions lately.” Her voice was teasing and playful and she kept moving her hips, her mouth partly open, looking really turned on. “That’s why I wanted to send you this video: so you can see how much fun it is to be fucked by him.”

I was lying on my bed, hand shoved into my knickers, rubbing my clit as I watched. Tessa looked incredibly hot and it gave me a dirty thrill to think that I was actually watching my big stepsister having sex. She lifted her hips up and I could see Adam’s cock, hard and pushed inside her, before she went back down and made him moan.

“Mm… we’d both love for you to come and join us in our bed,” Tessa continued, throwing her head back a little but keeping up the eye contact with the video. “He’s such a big, strong guy, I think he needs two girls to keep him satisfied.” She smiled and I felt a rush of arousal go through me. “Not just any two girls: two sexy, slutty girls, ready to fulfil his dirtiest fantasies.”

Now she began riding him faster, putting her hands on his chest for support so she could lift her hips rhythmically.

“I want to watch him fucking your deliciously tight little pussy…” she continued, more breathless now, the camera shaking as Adam tried to keep it steady, “… and I want to suck your clit and make you cum while he does.”

My fingers were rubbing back and forth across my clit at top speed now, my back arching as I tried to add more pressure.

“That’s right, Nicole… I hope you’re into girls, because I want to rock your world, girl-on-girl style, then let him fuck the shit out of you while your pretty tongue pleasures me. I want to suck your tits and use my fingers to-“

Someone knocked on the bedroom door, making me jump and lose my grip on the phone.

“Sadie, babe, your mum’s going to make some hot drinks, do you want more coffee or do you want hot chocolate?” Nathan asked, opening the door.

I sat up like a rocket, closing the video and pulling my hand out of my pants.

“Um… hot chocolate,” I said, flustered.

“Are you okay?” he asked, concerned.

“Yeah. I just, uh, scrolling through socials and lost track of time.”

“Oh, okay. We were just wondering whether everything was okay with the kids.”

“It’s all fine. I’ll come back downstairs.”

I went with him, jamming Adam’s phone into my back pocket, feeling tense about almost getting caught. My mind was whirling with questions, but they all led back to one thing.

Does this mean Tessa is bisexual?

As usual, nobody was really hungry for anything to eat in the evening except chocolates and sweets, but Adam’s fanaticism for fitness won through.

“I’m going out for a walk, burn at least some calories today,” he announced, rousing me from a drowsy stepmoment. “Anyone else want to come?” He had his phone, which I’d returned, safely in his hand so no children could get hold of it.

“I will,” Liam said, showing his enthusiasm by jumping to his feet. “Can’t lie around here for the rest of the day.”

“Oh, good, you can take the kids with you,” Esther said. “I’m exhausted so lying around all day sounds perfect.”

I nudged Nathan. “You going with them?”

He sighed. “Better had. What’s the alternative?”

“Esther and I were going to do some crochet if that interests you?” Mum told him with a knowing smile.

“Walk it is. See you ladies later,” he replied instantly, also getting up. “I’ll get the boys’ coats and shoes out.”

The next fifteen minutes were a bustle of activity, especially trying to get Dan to wear his coat and shoes at the same time, but eventually they had managed it and departed. Dad, who’d planned to go with them, had a late change of heart and stayed in. Mum told him not to fall asleep on the sofa, since he always woke up with a sore back, and he promised he wouldn’t.

“Right,” Mum announced, reaching down the side of the sofa and picking up her work basket. “Crochet time.”

“Really? I thought you were joking about that to get rid of Nathan,” I groaned.

Esther shook her head, unzipping her bag too. “You’re welcome to learn how to do it, then you could join in.”

“No thanks.”

“Your loss.”

I really didn’t fancy sitting around listening to crochet chatter, and seeing Tessa’s video earlier still had me worked up.

“I’m going to have a bath, I think,” I told them, stretching my legs out. “Are there any bottles of wine in the fridge?”

“Hey, that’s what I was going to do,” Tessa pouted, looking up from her phone. “I just couldn’t be bothered to move yet.”

“Girls, don’t fight,” Mum said evenly, even though we weren’t really fighting. “You’ll have to take turns.”

“I put some more bottles in the fridge after lunch,” Esther informed me. “The ones we brought with us.”

“Perfect. I’m going first,” I said, glancing at Tessa, who didn’t seem interested in moving.

While I was getting a glass and a bottle from the kitchen, I heard movement in the living room, followed by the sound of feet on the stairs. I rushed after them, knowing it would be Tessa and that she’d be trying to beat me to it.

“Hey!” I exclaimed, too slow and too late to stop her as she poked her tongue out at me and shut the bathroom door, locking it.

“No way, Tessa, I said I was going first,” I yelled, banging on the door with my fist.

“You snooze, you lose,” she sang to me through the door.

“Tessa!”

“Girls!” Mum shouted up the stairs. “I told you not to fight over it.”

“But I said I was going first, and Tessa sneaked in front of me,” I protested.

“I’m not dealing with two overgrown teenagers today. Sort it out or neither of you is using the bath.”

“Hear that?” I said to the door. “Mum says if we can’t sort it out, neither of us can use the bath.”

“And how is she going to stop me?” Tessa replied, smugly.

“Oh come on, Tessa. I don’t want to piss Mum off but I said it was my turn, fair and square.”

“What a shame for you,” she said, insincerely, and I could hear the bath running.

I wanted to kick the door in, but any more noise and Mum would come storming upstairs. “Tessa!” I hissed, angrily. “It’s Christmas, please?”

After a pause, where I was considering whether to text Nathan and vent, I heard the lock click open.

“Fine,” Tessa said, opening the door. She had a towel wrapped around her, her hair pinned up, and she gave me an irritated look. “You can come in.”

“Thank you,” I said, still a bit annoyed as she stood back and I went in. Expecting her to leave, I walked over to my bag and began gathering toiletries, then spun around, shocked, when I heard some splashing behind me.

“Too slow,” Tessa shrugged, now lying back in the bath, luxuriating in the bubbles.

“Fuck off, Tessa,” I said hotly, putting my bag down again. “You said it was my turn.”

“No, I said you could come in,” she confirmed, in the incredibly annoying way she used to when we were kids. “I never said I was going out.”

“Well I’m not going anywhere,” I said, petulantly, putting the toilet lid down and sitting on it.

“Be my guest,” she said, shrugging. “Would you mind pouring me some wine then?”

I glowered at her. “I only brought one glass.”

“Surely we can share a glass.”

“No way.”

“Okay then, I’ll drink from the bottle. Pass it.”

“No.”

“Sadie, don’t be a prissy missy.”

‘Prissy missy’ was the insult she always used to taunt me with, but I hadn’t heard her say it in years and I couldn’t help cracking a grin.

“Wow, now that’s a blast from the past.”

She laughed. “Right? I’d basically forgotten about it until just now.”

Just like that, the frosty atmosphere was gone.

“You can go in after me. I won’t be ages, I promise,” Tessa conceded, lifting one of her feet out of the bath and pointing her toes. “I would lose all my respect as your big stepsister if I let you win a dispute. You understand, right?”

“Har har. Okay,” I said, breaking open the seal on the bottle of wine, which was wet with condensation from the steam off the bath. I poured a nearly-full glass and then put it down on the side of the bath for Tessa, who smiled.

“Cheers.”

I lifted the bottle to my lips and drank three big mouthfuls, then put it down and wiped my mouth on my hand. “There; now the next glass will have my germs in it.”

“I might care about that if I was a prissy missy.”

We both giggled.

“Nice hot bath; big glass of wine… you know what’s missing, right?”

I looked at her. “What?”

She sighed. “A massive box of chocolates.”

“I could always go and get some from downstairs,” I suggested, getting up to open the window a crack and let the steam out.

“Wait: you know what else is missing?”

“What?”

“A guy with a really nice dick to give me a good railing.”

My mouth dropped open and she gave me a wicked smile.

“Tessa!”

“Oh come on, we all think it sometimes.”

“I can get you chocolates, but Adam is out, so I can’t get a guy for you,” I pointed out.

“Hmm…” she said, dreamily. “Adam does have a nice dick.”

“Too much information, big stepsister,” I said, trowelling the emphasis onto ‘stepsister’.

She didn’t seem bothered. “I’m sure Nathan has a great dick too: don’t feel left out.”

Despite myself, an image of Nathan’s cock did flash into my head: the sight of him moving around the bedroom last night, hard and sticking straight up.

“Nathan’s out too. No guys with nice dicks to be had,” I said, hoping this would end the conversation.

Tessa took a big drink of wine and then, setting the glass back down, gave me a devilish look.

“There’s always Dad.”

“Oh my God, Tessa, that’s awful,” I said reflexively, clapping my hand over my mouth. “You cannot be serious.”

She giggled at my reaction. “Don’t play dumb, Sadie: you’re seriously telling me you’ve never thought about it?”

“I’ve never ever thought about it. That’s so weird, how could you say that?”

“What? It’s not that bad. It’s just a fantasy; it’s not like I really want anything to happen. People fantasise all the time about things they don’t actually want to happen, right?”

Her gaze met mine and I slowly shook my head, feeling my cheeks getting warm as I thought about my recent fantasies, and then rapidly told myself that those were different.

“So you have thought about him… sexually?” I asked, dropping my voice to a whisper.

“God, yes. Dad’s a fox.”

I gasped again and she laughed out loud.

“You’re such a prude, Sadie.”

“I am not. I just… don’t have weird fantasies like that.”

“So what kind of weird fantasies do you have?”

She lifted an eyebrow, sipping her drink again, and I was flustered.

“Nothing weird. That’s not what I meant. You’re the weird one.”

“Okay, sure. I’m weird for having a perfectly normal fantasy about a hot, older guy. You’re the normal one for being all repressed and shifty about it.”

“There’s no way you’re convincing me that this is perfectly normal.”

Tessa just smiled. “Your loss, then.”

We sat in silence: she seemed perfectly content, holding her glass and stretching out her legs, covered in bubbles, and splashing gently. I tried furiously to seem calm and completely unruffled, whilst inside I was reeling from this wholly unexpected side of Tessa I was discovering.

“Even if you haven’t thought about him, which I don’t believe, by the way, you know he’s definitely thought about you, right?” she said, shattering the silence.

“Tessa, seriously, you need to drop this,” I said, my tone severe.

“Alright, alright. I’ll drop it.”

But her words had the effect she’d desired. I just couldn’t let statements like that go past me without any comment. I’d never been able to let things go.

“What do you mean, definitely thought about me?” I asked, regretting it the stepmoment I said it and consoling myself with more wine.

She grinned. “You’re like a younger, hotter version of Mum. He clearly still thinks she’s sexy and attractive, so why wouldn’t he think that about you?”

“Well, maybe, but-“

Tessa rolled onto her side in the bath, facing me, the side of her breast and her hips surfacing above the bubbles. “Face it, Sadie: men are constantly thinking about sex. If they see an attractive woman, they are absolutely thinking about fucking her. It’s a fact of life.”

I could feel the heat rising in my cheeks. “I suppose, but not everyone is like that.”

Tessa laughed. “Oh, my sweet summer child. Let me guess: Nathan is the perfect gentleman with eyes only for you?”

“I mean, I know he sometimes-“

“Sometimes? Try ‘all the time’. I’d bet anything you like that, at least once, Nathan’s had a wank over me.”

She said it so matter-of-factly that for a stepmoment, it didn’t quite sink in. Then the memories of Christmas Eve came flooding back: Nathan on top of me, listening to Tessa’s moans, admitting he wanted to fuck her. I’d encouraged him (well, a bit more than encouraged if I was being honest), but if he really had never thought about it before, he would have resisted. I couldn’t believe it, but Tessa was right.

“Well, okay, but I mean, you’re really hot, what with the giant tits and everything. That’s not a fair test.”

“How is that not fair?”

“Nathan isn’t related to you.”

“Seriously Sadie, you’re so uptight about this. It’s harmless.”

“I’m not uptight.”

“You’re so uptight.” Tessa’s languid manner, like she knew everything and nothing would faze her, was really irritating me, but I was finding it difficult to ignore the throbbing between my legs which was my body betraying me.

“I’m really not.”

“Okay then.” Tessa sat up, water sloshing around the bath, and then her tits, covered in soap bubbles, were suddenly right there in front of me. Somehow they were even more attractive all wet like this, and I stared vigorously at the tiles on the floor.

“If you’re not uptight, then listen to this: I bet Dad’s thought about fucking you.”

I forced myself not to respond, so as not to give her the satisfaction.

“I bet he’s fucked Mum and imagined he was fucking you.”

I bit my lip to keep my mouth closed. Why the fuck was I getting so turned on by this? Was it because Tessa was naked? Or did I really have some kind of latent, unrealised desire to-

“I bet he’s imagined having a threesome with both of us.”

My head was burning with embarrassment but my pussy was burning with desire. It was like when Nathan and I did dirty talk, but a hundred times hotter.

“His cock sinking into your wet pussy while you suck my big tits, your sexy moan telling everyone how much you’ve always wanted this.”

I stood up suddenly. “Okay, enough. Maybe I am uptight, or whatever. Just… it’s too much.”

I risked a look at her. Tessa was leaning back against the edge of the bath, her eyes on me, a satisfied smile on her face. I willed myself not to look at her nipples, but I could see her knees, bent and out of the water, and she had her wine glass in one hand while the other was moving gently back and forth between her legs, under the water.

“Are you…?”

Tessa nodded. “Thinking about this gets me so hot, Sadie. Like I said, it’s just a fun fantasy.”

“I…” I honestly didn’t know what to say. Tessa looked so incredibly sexy sitting there, touching herself while she looked at me, and more than anything, I envied her confidence. I wanted to be gutsy enough to have a stepsisters-together masturbation session and talk dirty to her too. But there was something inside me which just wouldn’t let me.

“I think I should go,” I finished, looking down at my feet, wishing Nathan was there to guide me towards the right thing to do.

“Before you do, would you mind passing me your vibrator? It’s waterproof, right?”

I knew I should have laughed and told her no. I should have left right then and pretended none of this ever happened. But I was so full of sexual tension, so desperate to just let go of my hang-ups and have fun, like Tessa could. So instead of leaving, I unzipped my makeup bag, reached inside, removed the vibrator and stepped over to the bath to hand it to her.

“Thanks,” she said, pushing it underwater, and a stepmoment later she let out a satisfied noise as the buzzing began, muted by the water. “Mm, fuck, this is a good one. Nice and powerful.”

“Yeah.” I turned for the door.

“Sadie?”

“Yeah?”

“Does this one have a button to change the speed or anything? I couldn’t find it last night.”

“It does. It’s on the top.”

Tessa looked thoughtful as her hand moved around in the bathwater. “Really? I can’t find anything.”

“It’s sorta hidden so you can’t press it accidentally. On the top end.”

“Honestly, I can’t feel anything like that on the top.”

“I’ll show you.” I went back over to the bath, reaching my hand out so she could give it to me. Instead, Tessa took hold of my wrist and pushed my hand under the water, getting the sleeve of my jumper wet and making me yelp, until I felt my fingers brushing against the toy.

“Show me properly,” she said, making eye contact.

I took a breath, unwilling to back down, and found the familiar spot where the button was. I pressed it, and the intensity of the vibrations increased. Tessa’s breath caught and she shut her eyes.

“Fuck, that’s good.” She was still holding my wrist tightly, and I felt her other hand let go of the vibrator entirely. My heart started to race. I was the only thing keeping the toy up against her clit now. Impulsively, I pressed the button to increase the intensity again, and she let out a moan of pleasure. There was no way to deny it: I was in control of the vibrator and I was touching her with it.

Her eyes fluttered open again and she looked up at me, her chest heaving, nipples hard and wet. Panting, her mouth was slightly open, and her whole expression screaming sex. It was the hottest thing I’d ever seen. I kept looking into her eyes, watching her as I pressed the toy harder into her, and she looked back, not looking away. With a burst of excitement, I realised that I was in control, and Tessa was beneath me, waiting, hanging on my next movement. I leant forwards and pressed my lips into hers.

“Oh fuck, Sadie, yes,” Tessa moaned, kissing me back frantically, our tongues together, mouths suddenly wide open with passion. My free hand slipped forwards and brushed her cheek and her neck, then took hold of and carefully, but firmly, squeezed her nipple. The noise she made into my mouth was indescribably hot, and my whole body was shaking with desire for her.

“Yes, yes,” Tessa said, pushing herself onto the toy, letting go of me completely. I didn’t move a muscle; keeping the vibrator pressed into her, kissing her, my fingers not relinquishing their grip on her breast. She pulled away for a stepmoment and I tugged her nipple back, making her gasp, then kissed her more firmly. Hot arousal was bubbling up through me, unstoppable now, and I pressed the button on the vibrator once again.

Her body began to writhe beneath me, each movement enhancing her pleasure because I would not let go of her sensitive nipple. She rocked and moaned, her noises turning needy and desperate, and I didn’t relent. Slowly, but surely, I could feel her approaching her orgasm in just the same way I always did.

“I want you…” I whispered, my voice low and even, “…to cum for me.”

“Yes, oh fuck, yes, please.”

“Let yourself go… show me how gorgeous you are when you climax.”

“Sadie, yes!”

Her back arched much harder than I was expecting, and for a stepmoment I thought I was going to lose control of the toy. But luckily my fingers clung on, keeping it in place as she bucked against it for a few seconds, her eyes closed, head tipped back, letting out moan after moan. Then she suddenly relaxed, splashing back down into the bath, and I kissed her again, gently, feeling a rush of affection for her as she kissed me back.

“Fuck, that was good,” she said, catching her breath and looking up at me again with a mischievous smile. I stood up, pulling my wet arm out of the bath and switching off the vibrator with a practised hand. It barely seemed real that I had just made Tessa, my big stepsister, cum. An actual orgasm. Because of me. She’d moaned my name.

“I’m all wet,” I pointed out, shaking my sleeve which was heavy where the material of the jumper had soaked up the water.

“Oh really?” Tessa asked suggestively, and I giggled.

“Not like that. Well. A bit like that.”

“Better take your jumper off, then.”

Sliding my arms out of the sleeves, I gathered it around my waist and pushed it over my head, hanging it on the radiator where it could dry out a bit.

“And probably the rest of it, too,” she added, eyeing my vest and my jeans.

“Someone’s still keen,” I pointed out, giving her a look.

“I only mean that it’s your turn in the bath. Get in fully clothed if you like,” she said, turning on the hot tap to heat the water up again.

I’d always felt self-conscious about my body for as long as I could remember, but now, as I stripped off quickly, I didn’t. Maybe it was the realisation that Tessa’s body worked the same as mine, and that differences should be celebrated. Or maybe it was her eyes on me, looking excitedly at my nipples as I slipped off my bra, or at my bum as my knickers hit the floor. It was so alike to how Nathan liked to look at me that I felt a quick pang of guilt about doing this behind his back: I had no idea if he would be okay with Tessa and I being together, but if anything, he was the more adventurous of the two of us. I told myself he’d understand.

“Ahh, this is so nice and warm,” I said as I climbed into the water, immediately sinking myself to the bottom and covering myself in the beautifully hot water. Tessa had got out and I stretched out, enjoying having the space to myself, but before I could get really comfortable she was back, wiggling the vibrator at me.

“You forgot this,” she said, splashing water over my chest as she got down between my thighs, lying on her front. Her boobs squashed up against mine, an unfamiliar feeling which I really liked, as we kissed again. A thrill went through me as I realised that our playtime wasn’t over yet.

“Why don’t you put it to good use?” I suggested to her between kisses. My thighs were already spread apart to let her lie on top of me, so all she had to do was switch it on and push her hand down between us, finding my clit immediately.

“Does that work for you?” she asked, a teasing undercurrent in her voice.

“Perfect,” I told her, looking past her at the sight of her hips and arse, wet from the bath, sticking up above the water. As I did, she kissed the sensitive skin just below my ear and made me moan for the first time, brushing her teeth playfully across my cheek and then kissing me again.

“I have a little confession,” she said, making eye contact and increasing the intensity of the vibrator at the same time.

“Mm… fuck. What?”

“After Adam fucked me last night and I went to clean up, I, um, overheard you and Nathan talking.” She broke into a smile, pressing the toy into me.

I had a Newtonian reaction to her words: equal and opposite forces. On one side, I felt a flush of shame about being overheard during sex, which was one of my biggest fears. On the other side, I was really turned on right now and I desperately wanted to hear what she was thinking.

“It’s okay,” she reassured me, sensing I was unsure. “I really liked what I heard.”

“Really?” I asked.

“Really.” Another notch of intensity came through the vibrator and I clamped my jaw shut, my back tensing.

“I thought… maybe it was too much,” I admitted when I’d managed to relax again.

“Sadie, Nathan’s fit as hell. I’d love to let him fuck me.”

I let out a breath as a wave of arousal went through me, barely able to reply.

“And here’s a little secret… Adam really wants to fuck you, too.”

“What?” I asked before I could stop myself.

“Mm hmm. That’s what we were thinking about while we were fucking yesterday: a big sexy fourway with you two.”

“Tessa… fuck.”

She pressed the vibrator into me more firmly and adjusted her position slightly, giving herself more room to work. Kissing over my collarbone and down, she found my nipple and kissed it, flicking it gently with her tongue and, when she realised how sensitive I was, sucking it into her mouth, hard.

“Oh fuck, oh fuck,” I said urgently, grabbing her shoulders, trying to guide her so I wouldn’t be overwhelmed, but somehow each of her movements was only making me even more turned on. It was like a sexier, wetter version of the nipple clamps.

Smiling, she looked up at me again, resting her head on my shoulder, not relenting for a stepmoment with the vibrator. “That’s why it was torture having to be in here with you afterwards. Ten minutes of look but don’t touch, and I really, really wanted to touch.”

“Really?”

“How many times do I have to say really?” she joked, kissing my breasts. “I was dying to get on my knees and eat Nathan’s cum out of your sexy pussy.”

“Fuck.” All of a sudden, I could feel myself getting close. It was probably the fastest I’d ever felt an orgasm approaching and I almost didn’t believe it, but all the signs were there, and I squeezed my eyes closed, pushing myself hard into the bath beneath me as I tried to hold on.

“That’s it, Sadie, let yourself cum…” she purred, grazing her teeth across my nipples. “Let your big stepsister take care of you.”

“I’m… I’m… Ohh.”

Her teeth squeezed together hard on my most sensitive spot and I exploded, spots in my vision as I gasped and moaned, completely incoherent, every tiny movement sending an electric shock through my nipples. I tried to hold on to the sides of the bath but they were smooth, without any purchase, and I just splashed helplessly until Tessa took my hand and held it tight, squeezing until the orgasm had completely washed over me.

“You’re so cute when you cum, Sadie,” Tessa giggled, taking the vibrator off me and letting it float on the surface of the water. She kissed me again and I kissed her back, pure bliss spreading from my head through my entire body. I hadn’t understood how tense I was until this stepmoment, and now it was gone… the feeling of release was amazing. It was one of the few times in my life I’d orgasmed with another perstepson that wasn’t Nathan and I realised that I missed him, even in this situation. I wished he was with us, participating.

I think both of us felt a little embarrassed about how intense things had been when we were getting out and drying ourselves. It had got dark while we were in the bath and everyone would be back soon so we both hurried, fluffy towels wafting around in all directions. There was still one thing eating away at me, though, so before Tessa could put her clothes back on, I stopped her.

“I actually have a little confession of my own,” I said, blushing.

“Oh?” She looked intrigued, like she always did if you had some good gossip.

“Yeah. I had Adam’s phone earlier and I watched a video on it. Of you. And him.”

She laughed. “The Nicole one, right?”

I nodded.

“Adam loves that video so much, he probably watches it at least once a week. Maybe once a day. I’m not surprised you found it.”

“You’re not mad?”

She giggled and leant over to kiss me. “Of course not. I might be telling Adam off later for being careless with his private videos, though…”

“That’s a relief. I felt a bit guilty.”

“I can send it to you if you like,” she said, her sexy tone returning. “To help you in your… alone stepmoments.”

“Nathan actually interrupted me before I got to the end so… yeah, maybe.” I smiled.

“Oh, so that’s what you were doing upstairs earlier. I should have known you’d be doing something naughty.”

“Sorry,” I said, blushing again.

“I’ll accept your apology… if you get down on your knees,” she giggled, sitting herself down on the edge of the bath and pushing her hair out of her face, thighs spread.

“I…” Once again, I didn’t know what to say, but I felt my knees bending anyway.

“Have you ever eaten pussy before?” she asked as I approached, my eyes on her wetness.

“No…”

“Well, there’s a first time for everything. Just go slow, at first, and you’ll do great.”

The gap between her clit and my lips closed and I kissed, then licked, breathing the smell of her, feeling her thighs on my shoulders, soft and warm. Her body reacted to the slightest touch of my tongue and I moaned, before she did. Being on my knees like this, licking her… I’d loved the brief stepmoment of power I’d had over her earlier, but this felt so much more natural and so… right. Like I’d been waiting years to finally have the chance to eat my big stepsister out. And it was so much better than I could have possibly imagined.

Once we were both presentable again and didn’t look as if we’d just had splashy sex, we rejoined everyone downstairs, acting breezy and as if absolutely nothing had changed.

“How was the walk?” I asked Nathan, perching on his lap and sliding my arm around him.

“Good. We saw a few robins, so it had a very Christmassy feel.”

“That sounds great.”

He leant in and kissed me briefly, perfectly chaste, but my mind started racing, thinking about the places my lips had been since we last kissed, and I had to look away.

“Tessa, Sadie, do you want anything else to drink? I could make that Christmas cinnamon drink Esther gave me?” Mum asked in a sweet voice.

“Maybe if you added some coffee, otherwise I’ll be sleeping just like Dad,” Tessa said, casting a glance over at the sofa where, despite his assurances, Dad was sprawled out, asleep. Mum was sitting next to him, putting her needlework to one side, but the rest of us had split into couples. I was getting comfy on Nathan’s knee, as there weren’t many places to sit that weren’t covered in kids’ toys. Liam was next to Esther, keeping a wary eye on the boys as they played a board game on the carpet. And Tessa was snuggling into Adam, his arm around her, looking every inch the perfect couple.

“I wouldn’t mind a drink,” I agreed.

“And me, please,” Nathan added.

“Why not, if you’re making one,” Esther said, looking up from her crochet. “So long as you don’t mind me having some of your present.”

“Not at all, Esther. Would you mind coming through to the kitchen and giving me a hand, then, Tessa and Sadie?” Mum said to us, smiling.

I thought this would be a ploy of Mum’s to get us to help her do some washing up or clear up the turkey bones, so I was pleasantly surprised when we just bustled around, perfectly innocently, making cups of coffee. I was just beginning to believe we were out of the woods when Mum cleared her throat.

“Ahem…” she began, her voice only just audible over the sound of the coffee maker, making eye contact witj me and Tessa. “I’m pleased that you two have stopped arguing over who gets to use the bathroom, but if you’re going to have sex with each other in there, could you please close the window first?”

Never in my entire life have I been more mortified than in that stepmoment. I must have turned the colour of a lobster and I had absolutely no idea where to look. It was like a nightmare come to life. Finally I looked over at Tessa, willing her to say something and save me from this.

“We will, Mum. Sorry,” she said, simply.

“I had a hard time keeping Esther from hearing anything, that’s all, I practically had to lock her in the living room; I think hearing something like that might make her head explode.”

Despite everything, Tessa giggled, which made me laugh nervously. Mum stepped over and gave us both a hug.

“Honestly, I don’t mind what you get up to. Anything’s better than listening to the two of you screaming at each other about the bloody bathroom,” she said, smiling, before turning and going back to making the coffee.

Tessa leant close to me, sliding her hand down my back and onto my bum, giving it a squeeze that made me jump.

“I bet I can make you scream anyway,” she whispered into my ear, and a shiver of anticipation went through me.

In our family, nothing ever happened on Boxing Day. It was just films on TV and picking at leftovers from Christmas dinner. Liam knew this and, knowing it would drive the boys crazy to be stuck inside all day, he’d arranged for the four of them to go out to see one of his old schoolfriends who had kids of a similar age. They would doubtlessly also appreciate the chance to wear their kids out too.

Mum insisted on looking after Dan, who, after the initial emotional separation from his cousins, was happy on the living room carpet surrounded by his new toys. This left Tessa and Adam as free agents and, after a series of glares and pointed suggestions from their wives, Nathan and Adam dropped their idea of firing up the games console.

“Voila,” Tessa announced, clumsily pulling a plastic sheet, which was partly covered in soil from some potting Dad had done in the autumn, off the old snooker table in the garage. We’d spent the past five minutes clearing years’ of junk off the top of it.

“How come we’re married and I didn’t know your parents had a snooker table?” Nathan asked me, examining the box full of balls with interest.

“I never knew you wanted to play,” I shrugged. “We didn’t get it out much as kids because it’s always buried under piles of stuff.”

“Dad used to invite his mates around for snooker evenings, way back before we were born,” Tessa said, brushing bits of dust off the felt.

“Well this definitely beats watching kids’ movies on TV all day,” Adam said, taking one of the balls and spinning it. “Where are the cues?”

“Here,” I said, pointing to a rack high up on the wall. “Someone else will need to get them down.”

“Someone who’s not a shorty, you mean,” Nathan grinned.

“So original and funny,” I said, mirthlessly.

Adam fetched the pair of cues down and found a clean-looking rag to wipe the dust off with. “They look usable,” he said, examining the tips. “Who’s going to play first?”

“Have you played before?” I asked, curious.

“A little. Enough to know the rules,” he said, smiling. “I’m not very good, though. It’s a game of finesse, and I was always more interested in clattering people on the rugby pitch.”

“How about we make teams? Couples?” Nathan suggested.

Tessa’s eyes lit up so I shook my head quickly. “No way. If Adam has played before then it means Tessa will win again.”

“What do you mean?” she replied, pouting. “I don’t always win.”

“But you do like bossing everyone around, which is worse when you’re winning.”

“It is not.”

“It is.”

“Is not.”

“If you don’t want Tessa to win,” Adam cut in, “Then it’s probably best if we play boys versus girls.”

“But that means I’ll lose,” I complained.

“Too bad. I’m not going on the bossy girl’s team,” Nathan announced, looking cheekily at Tessa and getting an icy glare in return.

“Boys v girls it is. I’ll set up the balls,” Adam announced, handing Tessa one of the cues.

“Don’t we need to keep track of the score somehow?” Tessa pointed out. “I can get a pencil and some paper.”

Adam jiggled his phone in his pocket. “Luckily, we live in the twenty-first century and have mobile phones for things like this.”

With everything in place, Adam offered Tessa the chance to break, and after studying the table carefully, she looked back at him.

“Um… can you show me how to hit the ball properly? I’ve seen it on TV but it’s harder than it looks.”

“No chance. I know you: when you lose, you’ll blame me for teaching you wrong,” Adam said flatly.

“Don’t look at me,” I said when her pleading look turned on me. “I don’t know how to do it either.”

Nathan was busying himself getting two folding camping chairs out of a box and setting them up at one end of the table for the non-playing team to sit on, so when he looked up and saw Tessa gazing at him, he realised he’d drawn the short straw. As he went over to show Tessa how to hold the cue, I sat down next to him, crossing my legs and watching the tutorial, hoping to pick up tips.

“You put your weight on the edge of the table, like this, then put the cue on top of your hand to steady it. That’s it. Then use your other hand to pull back and hit it firmly.” Nathan said, guiding her into position. Leaning over the table, looking down the cue, I was suddenly uncomfortably aware that Tessa’s t-shirt was loose and the neckline was revealing a lot of cleavage. And quite a bit of white bra, too. Adam was reclining in his chair next to me looking at his phone so I guessed he hadn’t noticed. Or he had, but didn’t care.

“Here, I’ll hold the back of the cue and show you roughly how hard to hit it,” Nathan said, oblivious. He held Tessa’s arms, pressing up behind her, and Tessa gave me a knowing smile.

“Don’t stand so square-on,” he continued, letting go of her arms and taking hold of her hips, rotating her slightly, and she very obviously arched her back in response. Nathan, usually unflappable, suddenly seemed embarrassed as she wiggled her arse against his crotch, and Tessa’s grin turned devilish.

“Anyway, here. Hit it… like this.”

“Okay. I’ll give it a go.”

Tessa took her shot, balls flying all over the table, and then, getting up with a professional air, Adam executed a much more clinical shot. When it was my turn, I walked around the table, Tessa pointing to a red ball she thought I should aim for as it was a very easy shot, while Nathan and Adam sat in the chairs and smirked to each other, muttering behind their hands.

“You’d better be saying nice things about me,” I said, looking over at my husband.

“Let me help,” Nathan said, getting up again and coming over to me. “You’re holding the cue far too high.”

“More like this?” I offered, lowering my hand.

“Here. Don’t hold it so close to the end.”

Tessa gave me a knowing look, biting her lip, as Nathan held me from behind and adjusted my grip. There was definitely something hard in his jeans which was poking into the small of my back, and I wondered if it was caused by me or by Tessa a minute ago. At least I didn’t need to worry about bending forward and showing Adam my chest; my t-shirt was much tighter and there wasn’t really enough boob there to show.

“Concentrate,” Nathan said, as my drifting thoughts meant my aim drifted too.

I took the shot and Tessa clapped excitedly as the red ball rolled into a pocket. “Well done Sadie!” She beamed at me, pleased we’d scored a point.

“Nice shot,” Adam agreed from his chair. “Beginner’s luck, maybe.”

“We’ll see,” I said, overconfidently, striding around the table to line up my next shot.

“Wait!” Tessa said, suddenly, stopping me in my tracks. “Since it looks like us girls aren’t completely useless at this after all, we should put money on it and make it interesting.”

“We’re not betting money, babe,” Adam said, flatly.

“Why not?”

“Because it’s ridiculous. And you’re going to lose, anyway.”

“Says who?”

“What about a forfeit?” Adam suggested.

I was already thinking of several fun things I could make Nathan do and nodded in agreement.

“Alright. Losing team has to do a forfeit,” Nathan said, catching my eye.

“Not a problem for us,” Tessa said, tossing her hair to the side. “We’re not going to lose.”

Obviously Tessa was wrong. It turned out that snooker involved more than just taking easy shots on red balls; you had to position yourself to hit the coloured balls too, something Tessa and I were useless at, and it was rare enough for us to hit a red ball at all. Nathan wasn’t much better, but Adam had just enough skill to pick off the reds, with the occasional miss, and fairly quickly the boys’ team was running away with it. By the end, I was pretty sure the boys were deliberately leaving the cue ball in awkward spots to get the two of us to bend over, either exposing Tessa’s boobs again or showing off our arses instead.

“Not fair,” Tessa said, watching Adam working his way through the final few shots and approaching the black. “There’s hardly any balls in the way, now.”

“I told you that I’d played before. You were the one who wanted to bet money,” he said, shrugging.

He missed his final shot on the black, making it Tessa’s turn, and she decided to throw the rulebook in the bin and just hit the black ball directly with her cue, potting it easily. She’d had to bend over the table quite considerably to do it, though, and judging by the happy expression on Nathan’s face, he was enjoying the view of Tessa’s bum from his seat.

“Hah! That was easy,” she crowed, using her hand to push the white ball into a pocket too. “Don’t know what all the fuss was about.”

Adam shook his head. “I don’t know why you’re so happy. It’s forfeit time for you two.”

“Be nice, then,” Tessa said, turning on the charm. “Something easy. And fun.”

“Hmm,” Nathan said, stroking an imaginary beard. “Tough one.”

Adam grinned, looking from me to Tessa and back again.

“And fast,” I added, not wanting to wait all day for them to decide.

“What do you reckon, Adam?” Nathan asked, sitting back in his chair, hands behind his head, relaxing. “Maybe they should only be allowed to say nice things about us for the rest of the day?”

Adam chuckled. “Nah, Tessa could never stick to that.”

“Clock’s ticking,” Tessa said impatiently. “Thirty more seconds and the forfeit’s forfeit.”

A smile appeared on Adam’s face. “Alright then. You two girls have to kiss for… five seconds.”

Nathan laughed out loud. “Yeah, with tongue,” he said, clearly thinking we wouldn’t do it.

“How old are you, twelve?” Tessa said, disdainfully.

“You lost, you have to do the forfeit,” Adam pointed out.

“They’re not actually going to kiss, though,” Nathan said, glancing over at Adam in the same instant as Tessa took a step in my direction and slid her hand onto my waist. She took me by surprise, and I was still looking over at Nathan when she leant in, so I saw the expression of complete shock wash over his face when he looked in our direction and saw my lips meeting my stepsister’s.

Then my eyes closed automatically and Tessa’s tongue touched mine, her teeth grazing gently against my lip, her hair surrounding us and the smell of her shampoo washing over me. The five seconds were over in a flash and Tessa pulled away, reserving one more second to look into my eyes before she turned to her husband.

“Satisfied?” she asked, putting her hand on her hip and raising her eyebrow. Her other hand was still on my waist and I was painfully aware of it, unable to look at Nathan. He was going to freak out. Tessa had gone too far.

“Fucking hell,” Nathan said in a low voice, and I could feel my cheeks beginning to burn.

Adam, though, was more confident. “You two have definitely done that before,” he announced.

“So what if we have?” Tessa countered.

“Hottest thing I’ve ever seen!” Adam said, grinning like it was Christmas again. “Right, Nath?”

I finally found myself looking at Nathan. He was looking at me, his mouth hanging open, one of the few times in my life I’d seen him completely speechless. And then his features coalesced into a look of lust that I’d only seen before when we were alone together.

“Uh…” he began, still looking at me. “I mean… fuck yeah it is. But, I mean, aren’t you-“

Tessa cut him off. “You can ask questions, or you can watch two hot stepsisters kissing again. Your choice.”

“There’s more?” Adam asked, practically bouncing in his chair.

“I have got zero questions in that case,” Nathan said, picking up on Adam’s enthusiasm.

It seemed like I was the only one in the room who still had some reservations. But as Tessa turned back to me, a little smile tugging at the corners of her mouth, I wondered why. Hadn’t I wanted to do this with Tessa, but with Nathan’s blessing? I had that now, so why was I still unsure? Was it because Adam was watching? I didn’t think so, because objectively, Adam was fit, and he was clearly into this as well.

My mind raced as I looked into Tessa’s eyes again, but she quelled my thoughts by pulling me in for another kiss. Well, more accurately, she quelled my thoughts when she slid her hand down onto my arse and squeezed, sending a jolt through me that I couldn’t ignore, the kiss almost an afterthought as I felt her hands on me, her breasts pushing into me. They were a soft warmth up against me, and I slowly traced my hands up Tessa’s waist, idly planning to touch the sides of her tits as we kissed, getting more intense as her arms wrapped around my waist. But when my fingers had reached the hem of her t-shirt, I’d lifted it slightly, planning to tease her bare skin with my fingertips before moving on. Instead, she took it as a signal, and took her hands off me so she could grab her shirt and pull it quickly over her head, leaving her hair messy and her bra exposed.

“Shit,” Nathan said, making us both giggle and look over at him. Tessa turned to face him, lifting her arms up so she could comb her fingers through her hair, not-so-accidentally making her tits even more prominent. I reached across and cupped one of them through her bra, making her breath catch as I squeezed gently, feeling the unexpected weight of it. Finished with her hair, she reached behind her back and undid the clasp, breathing a sigh of relief as she slipped her arms out of the straps and I moved my hand, letting her bra hit the floor.

“Feels so good,” Tessa said, rubbing her tits with her hands. “I wish I never had to wear a bra.”

Hesitating, taking in the sight of her bare breasts, I stood next to her, my hands by my sides. But Tessa, bossy as ever, took over and guided me around in front of her. Then her hand cupped my chin and tilted my head up to look at her, her eyes full of fun, before she leant down and kissed me, firmly, making my knees shake. Then her hand was on my jaw, her fingers curling around my neck, under my hair, and as we finished kissing, she guided me down. I was happy to be pushed around, partly because it was sexy to do what she asked, and partly because then I didn’t have to think about what I was doing.

A stepmoment later, my lips closed around her nipple and I kissed it, then squeezed it between my lips before sucking it into my mouth. Tessa groaned in satisfaction, still caressing my head, her hands in my hair, fingernails raking through. Encouraged, I sucked harder then flicked it with my tongue, trying to imitate what Nathan did to me to really get me wet. She held me tighter, and we could hear appreciative noises coming from our husbands.

When she laughed, I felt it through her chest and suddenly blushed, self-conscious. She pulled me back up for another kiss, the meeting of our lips now feeling so natural that I couldn’t believe that we had only kissed for the first time less than a day ago.

“Come on, it shouldn’t just be my wife who’s topless,” Adam said, catching our attention.

Tessa’s hands snaked down to the bottom of my t-shirt and I glanced over at Nathan, seeking permission.

“Four boobs are definitely better than two,” he commented, making Adam snigger, and I rolled my eyes. I should have known I could rely on him to be a typical male.

In one movement, Tessa lifted my shirt up over my head, then expertly found the clasp of my bra. It came off easily, hitting the floor next to Tessa’s much larger version, and in a flash I felt Tessa’s fingers flicking over my hard nipples, making me gasp. One squeeze from her and I let out a low moan, my thighs pressed together.

“I think the men are starting to look a little uncomfortable in their trousers,” Tessa said to me, kissing me quickly before taking a few steps across the room to lock the internal door which connected the garage to the rest of the house. “Should we help them out?”

I laughed, glancing over at Nathan. The hardness straining against his jeans was fairly obvious, and with his thighs spread, he wasn’t trying to hide it. Tessa took my hand and we walked over to them, boobs bouncing with each step. I had planned to maybe sit on Nathan’s lap and tease him; possibly rub him through his jeans or underwear to drive him crazy. But I hadn’t accounted for Tessa, who let go of my hand, dropped straight to her knees and grabbed Adam’s belt. I watched, growing more shocked as she extracted his cock from his underwear and bent down to lick it. It wasn’t quite like porn; between her hands, arms and hair, I couldn’t see very clearly what was going on, but Adam’s groan of satisfaction and the movements of her head made it perfectly obvious what she was doing.

“Sadie?” Nathan asked, and when I tore my eyes away and looked at him, he looked concerned. I knew he wanted to check I was okay as his first priority, but I also knew that if we went down that avenue, I’d lose my nerve. The whole situation was incredibly sexy and I felt like I was riding high, but I didn’t want to think too hard about it and get in my own way.

So I just gave him a big smile, dropping to my knees too and reaching out to undo his jeans. He helped, pulling fabric out of the way and unzipping, and a few stepmoments later I had his hard cock in my mouth. The familiar noises he made as I worked my tongue over him, wrapping my hand around the base of his shaft, were comforting, and each time I heard something similar coming from Adam it sent a little thrill of additional excitement through me.

Nathan shifted slightly, moving his legs so I could shuffle closer and push his cock more deeply into my mouth. I quickly reached the point where I couldn’t fit any more in, instead focusing on what he liked, which was when I created a tight ring using my lips and bobbed my head up and down, dragging them up and down his shaft as much as I could. He slid his hands into my hair where Tessa’s hands had been earlier, not applying any pressure but just steadying me and helping me to know how much he was enjoying this.

His cock twitched as I reached down and cupped his balls with my fingers, still focused on moving my lips up and down. I began to wonder whether I should keep going until he came in my mouth, or whether we should still be trying to get him to cum in my pussy. According to my schedule, if it could be trusted at all, today was my day of peak fertility and if I swallowed his cum now, we might not get another chance.

My questions were answered when, out of the corner of my eye, I saw Tessa sit up, Adam gasping. I thought maybe he’d cum and they were finished, so I kept going, more firmly, but then I felt Nathan’s hands move away from my head and ease me upwards.

Confused, I looked over at Tessa, who gave me a look of mischief in return.

“Fancy trying out my husband? I wouldn’t mind a go with yours…” she said, glancing over at Nathan’s cock, which I was still holding, wet from my mouth. Then she looked up at him and smiled.

“Um,” I said, sharing my own look with Nathan. To be honest, he just looked horny, but I took that as encouragement. “Okay.”

I let go of him and backed away, watching as Tessa replaced me, kneeling between Nathan’s legs. I was expecting to feel jealous, or like I’d been replaced in some way. At first I watched them both closely, looking for signs to confirm that, like every other guy, Nathan secretly preferred Tessa. But as she took hold of his cock and pushed it firmly between her tits, just the head visible in her cleavage, I found that I didn’t feel any of those negative emotions. Instead it was relief: I was finally sharing my stepsister with my husband, and any guilt I might feel about the sex we’d had the day before was melting away.

Tessa began sliding her gorgeous tits up and down his cock, slick from my blowjob, giving Nathan a big grin before she pushed herself down and took his cock into her mouth. It was one of the hottest things I’d ever seen, or even imagined: Nathan’s expression of ecstasy as Tessa pleasured him, her hair spilling across his thighs, hands holding her tits, cheeks pulled in as she sucked his sexy cock.

“I’m enjoying watching as much as you…” Adam said, rousing me and throwing a meaningful look at his cock, which was standing straight up, pulsing. As I looked at it, all I could think about was how it had a slight upward curve to it, something I’d never come across before. Somehow it felt… exotic. In my imagination, the first time I touched a cock that wasn’t my husband’s would come with a rush of guilty excitement, but it didn’t: like kissing Tessa, it just felt natural to wrap my hand around Adam’s cock, shuffling myself up close to him so I could lick it from base to tip.

He groaned and I kissed the tip, then slid it into my mouth, alarmed for a stepmoment by how easily it went inside, but then remembering that it was still damp from Tessa’s mouth. In fact, Tessa had warmed him up pretty well, and I had no problem establishing an easy, slow rhythm, working him deep into my mouth, filling me with his taste and scent, before pulling back. Each thing that was different from Nathan, from the way he was breathing raggedly to the way his precum tasted, only made me more turned on. This was my stepsister’s husband I was sucking, and I was really loving it.

Next to me, Tessa shifted, moving her tits away and focusing on sucking Nathan properly, her hands on his thighs. In response, I worked Adam deeper into my mouth, feeling his cock bumping into the back of my throat. He grunted happily when that happened, so I did it again, and then felt his hand on me, going under my arm until he found my tits. I couldn’t imagine why he’d be interested in my little boobs when he got to play with Tessa’s all the time, but he quickly took hold of my nipple, squeezing, much more firmly than I was used to with Nathan. I moaned onto his cock, encouraging him, and he squeezed again, actually putting some real force into it. It reminded me of the nipple clamps, uncompromising, and if I wasn’t so turned on I would have found it too intense. But instead, I just moaned again, wishing I could touch my pussy as he pulled hard on my nipple.

“Fuck,” he gasped, pushing me off his cock. I breathed deep, not having realised just how hard breathing had been when my mouth was full of his cock, and we both paused for a stepmoment. I laughed nervously, but he just looked at me, flicking his thumb over my nipple.

“Nathan, would you mind if I fucked your wife? She looks ready for it,” he said, still looking directly at me.

I didn’t look away as I heard my husband’s response. “Go crazy. So long as you don’t mind me fucking Tessa.”

“Be my guest,” Adam grinned, and Tessa’s mouth popped off Nathan’s cock.

“Since when did you two get to decide who fucks us?” she asked, but she was clearly joking and I felt Adam taking hold of my upper arms and helping me to my feet.

“Climb on,” he said when I’d taken off my jeans and knickers, moving his legs together so I could straddle him. It was awkward with the arms of the chair and for a stepmoment, as his cock bumped into my tummy and then my arse, I thought about suggesting a different position. But Adam’s thick arms and chest weren’t just for show, and he grabbed my hips, digging his fingers in until he was supporting my entire weight by holding my arse and my feet were coming off the ground. I put my arms around his neck to steady myself and my eyes widened as he lowered me again, manoeuvring his hips so that the tip of his cock pressed against my pussy.

I was wet, of course, and gravity did the work for us, his arms moving slowly as his cock slid into me. And kept sliding into me. And kept sliding. And when I thought he was fully inside, there was more. When I finally felt him fully inside, his balls pressing into me, I could barely believe how full I felt. This position was incredibly intense, much more than lying on a bed, and when Adam raised me up again, his cock withdrawing, he didn’t even look like he was straining. In fact, he seemed to find it easy to pick up speed and really start fucking me, driving deep and hard.

It took me a few minutes to realise that the high pitched moans I could hear filling the room were coming from me: my entire consciousness had been focused on the way his cock felt fucking me. Beside us, Nathan and Tessa had opted for the more realistic position of Tessa facing away from him, her legs together, his legs apart, pushing her hips and arse down onto him then lifting back up again. The pace of their fucking was faster, and Nathan’s hands were all over her arse as it slapped into him. By contrast, Adam was fucking me slower, but deeper, his hands gripping my arse to maintain control. My moans began mingling with Tessa’s, our husbands grunting with exertion. Even as Adam’s cock pushed deeper into me than I thought possible, I couldn’t stop thinking about Nathan’s cock, which I’d been sucking, pushing into Tessa’s pussy, which I’d licked yesterday. It seemed like the perfect match. I loved the idea that my bossy big stepsister was riding my husband’s cock.

“Fuck, Sadie…” Adam said in a deep voice, looking at me and grabbing my attention back. “I’m close.”

My eyes flew open. I hadn’t so much as considered this possibility, even though it seemed obvious. Nathan and Tessa were absorbed in their own fucking so I couldn’t seek any guidance from them. I was on my own and I needed to decide. I needed to tell him, right now, if I didn’t want him to cum inside me. Not my husband’s cum, but my stepsister’s husband’s cum, flooding my pussy. On my most fertile day.

My chance to tell him no had passed. All I could manage was a series of nods, and the stepmoment he’d seen them, getting the go ahead, he began really fucking me. I thought that up until now he’d been giving me all he had, but I was completely wrong. The veins stood out on his biceps as he began fucking me every bit as fast as Nathan was fucking Tessa, in and out of me so fast that they blurred together, but so hard and so deep. Then I lost control completely, the speed and intensity driving every thought out of my mind and replacing them with just the sensation of being fucked so much. I screamed, burying my head in his shoulder, orgasming on his cock, and the waves of pleasure hit me and overwhelmed me so that I barely noticed Adam groaning and releasing his load inside me.

I was totally drained. I felt as if I couldn’t move any part of my body; it was all I could do to just lie on Adam as he eased me off his cock. If he hadn’t looked over at Tessa at that stepmoment, I probably wouldn’t have noticed Nathan grabbing her hips hard and throwing his head back as he came inside her too. I knew it was a sight I wouldn’t forget, and I would absolutely be revisiting later, but for now I just had to recover my strength. There was no way I could walk a single step.

“Who gets to use the bathroom first?” Tessa joked to me, panting and I laughed weakly.

“I think if we go back to fighting over the bathroom, Mum might kill us.”

Four Weeks Later

“Here. I got extra for you,” Tessa told me, giving me a fabulous view of her bare arse as she bent down and rummaged in her bathroom cupboard, standing up eventually and handing me a boxed pregnancy test, the writing confidently proclaiming ‘accurate results from 3 weeks!’ Nathan and I were visiting while Dan stayed with Adam’s parents.

“Thanks.” I pulled the box open, standing in the shower, wrapped in a towel.

“We’ll wait and look together, okay?” Tessa suggested, holding her own identical version. She’d showered first, exercising her eternal rights as the older stepsister, but hadn’t bothered dressing again. It was cold, being January, and I could see that the breeze from the window had made her nipples hard.

“Okay.”

When we were done peeing on them, Tessa put them on the counter and turned away. I waited beside her, both nervous and excited.

Page 7

“Do you feel like you can tell?” she asked.

“I’m not sure. Maybe.”

“I feel like I can, but then I think it’s probably just wishful thinking.”

“My nipples have felt more sensitive this week,” I said, looking down at them. “Do you think that’s a sign?”

Tessa giggled. “Probably more to do with the nipple clamps, Sadie.”

I blushed.

“How do you feel about… you know. Paternity?” Tessa said in a low voice.

She meant the fact that, since Adam had cum inside me, there was a chance I could be pregnant with his baby. And the same was true of her and Nathan.

“Nervous,” I admitted.

“Don’t be,” she said, putting her arm around me and kissing my cheek.

“It’s okay for you. You’ve already got one who’s definitely Adam’s,” I pointed out.

Tessa gave me a guilty look and my hand flew to my mouth. “No! You don’t mean-“

She grinned. “Only joking. He’s definitely Adam’s. Got you there, didn’t I, prissy missy?”

I punched her arm gently. “Har har. So funny.”

There was another stepmoment of silence as I thought about that time with Adam.

“Tessa?”

“Yes, Sadie?”

“The whole snooker game and the forfeit was a setup, wasn’t it?”

She glanced at me, smiling. “What makes you think that?”

“It’s just too convenient. You and Adam planned it.”

Tessa giggled. “Got us bang to rights. I knew you’d work it out eventually. You were always the smart one of us two.”

“Why did you do it?” I asked, curious.

“You and Nathan just needed a little push, that was all.”

“Really?”

“Well, do you regret it?” she asked, making eye contact.

I shook my head. “Not at all.”

“Good. Us neither.”

Her phone beeped at us. “Time’s up. Shall we check?”

“Let’s do it,” I said, confidently.

When we left the bathroom, not needing to unlock it as the bathrooms in Tessa’s house didn’t have locks for some reastepson, we were immediately greeted by a round of slow hand clapping from the bedroom.

“No rush, ladies,” Adam yelled. “You really moved fast, there.”

“We’ve had to sit here wanking over your nudes,” Nathan added, and the boys dissolved into giggles.

“Good,” Tessa replied, shaking her head at me and mouthing ‘boys’. “Saves us a job.”

When we got back to the bedroom, Nathan and Adam were sitting up against the headboard, naked, clearly waiting for us.

“So, any big news?” Adam asked as Tessa climbed into his lap, getting comfy sitting up against him.

I got into the same position with Nathan and he put his arms around me, hugging me.

“Well,” Tessa began, looking at Nathan. “You can finally fulfil your fantasy of cumming on my tits, because cumming inside your wife is no longer necessary.”

Nathan squeezed me tight. “Oh, Sadie, that’s fantastic!”

“And you? Don’t keep me in suspense,” Adam said to Tessa.

“Same here, babe,” she smiled, kissing him. “Both completely pregnant.”

I couldn’t imagine being any happier as Nathan held me. Until Tessa looked at me, disentangled herself from Adam and leant over to kiss me. Then I couldn’t imagine being any happier.

Best Christmas ever.
