My Twin Sister's Wife Wants a Baby

I've had this idea rattling around my brain for a while and I finally have been able to get it ready to publish. As per usual anyone participating in sexual activity is 18 or older. Reality and this story have some overlap but it is not 100%, any inaccuracies are for the betterment of the story. It could probably fit into several different categories, but I'm putting it here even without any direct incestuous contact. Leaving myself some room in case it goes there. Write a comment to let me know if you'd like to see more like this.

*Five Years Ago*

Doc Brown's buzzed with the usual weekend crowd--only tonight, it was louder, rowdier, and sweatier than usual. Midterms had just ended, and the relief was flowing, like the beer. The place was packed, a writhing sea of college students looking to forget. The silver lining to all the chaos? More girls, and no live music--the usual cover band had been bumped to make room for drinkers. It was the kind of night that promised stories.

I had just taken a swig of whatever beer came with the cheapest pitcher Sam could find when I noticed her. She stood at the end of the bar, alone but self-assured, swirling a blue cocktail in her glass. Her crimson satin blouse clung to her like temptation itself, tucked into tight black jeans that made her legs look like they went on forever. Her dark hair was cut in a layered, spiky bob, brushing just above her shoulders and perfectly framing her high cheekbones and lips curled into a smile that hit like a gut punch--even from across the room.

Sam nudged me with her elbow. "You know her? She's been glancing over here for the last few minutes."

I shook my head. "No, but I want to," I said without thinking, earning a playful smack to the back of my head.

"Way out of your league, bro," Sam laughed as I rubbed the sting away and finished my beer.

"Such a hater," I muttered, already standing. "I'm going over anyway." I flipped the old one-finger salute behind my back as I headed toward the bar.

I wove through the crowd and slipped in on her right side. Up close, she was even more intimidating--everything about her was sharp and effortless. Just being that near made me want to turn around. Maybe Sam was right.

Before I could bail, she turned. Our eyes met. Her green eyes sparkled under the flickering neon bar lights, locking onto mine with a kind of amused curiosity. Then, slowly, she gave me a once-over before that magnetic smile returned.

"Damn it," I said before I could stop myself. "You found my weakness right away. I can't resist a pretty girl with a smile like that."

She giggled--an actual, unguarded giggle--and her smile widened into something genuine, something that reached all the way to those hypnotic eyes.

"Jules," she said, raising her glass toward me.

I clinked my empty glass gently against hers. "Will."

I was about to say something else when I noticed her glance over my shoulder--toward our table. Toward Sam.

"So, Will," she said, her voice light, "is that your girlfriend over there?"

I laughed, caught off guard. "Sam? No, she's my twin sister."

This time her smile changed--less polite, more... intrigued.

"Okay, that makes this easier then. You seem very sweet, Will, but I was kind of hoping she'd come over instead."

Before I could process that, she slipped past me and took my hand, tugging me along behind her. "Would you introduce me?" she asked, glancing back over her shoulder with a pout that no human being could refuse.

I stood by, dumbfounded, as Jules met Sam. Sparks flew. Then they danced. Then they kissed. Then they left--together.

The next morning, I woke up slightly hungover and desperately hungry. I pulled on a T-shirt and opened my bedroom door just in time to see Sam and Jules slipping out of our shared bathroom, wrapped in nothing but towels, giggling like teenagers as they ran into Sam's room.

"Told you she was out of your league, bro!" Sam called, slamming her bedroom door behind them.

And that... is how I introduced my sister to her wife.

/////

I always knew Sam was into girls. Probably before she did, honestly. It wasn't some "twin intuition" or anything--it was just obvious. I saw the way she looked at women. The same hungry, appreciative look I'd see on the faces of my friends. The kicker? Sam and I had the same taste in women--long legs, dark hair, and a great ass. Jules had all of that, plus a summa cum laude intellect, a razor-sharp wit, and those damn eyes. If she'd passed me by for anyone but Sam, I would've been crushed.

Instead, I spent the next year and a half being teased and tormented--constantly. Brief flashes of skin from our shared bathroom, Jules wearing nothing but one of my old T-shirts and panties in the morning, and the worst part: discovering my sister apparently had a "fucking magical tongue" courtesy of Jules screaming through our thin apartment walls.

I'd be lying if I said I'd never noticed how beautiful Sam was. We had the same All-American blonde hair, blue eyes, but where I had the lean lines of a swimmer, Sam had the curves and definition that came from years of gymnastics and cheerleading. If I was attracted to Jules, by all logic, I should've been just as drawn to Sam--aside from the whole sibling thing, obviously.

After we graduated, Sam and Jules got engaged fast. Small wedding. Beautiful. Simple. It was perfect.

That night, Jules introduced me to her coworker, Eva who is now my fiancée. Later, she told me it was her way of thanking me for bringing her and Sam together.

/////

The house was quiet now.

Everyone else had left after a long Friendsgiving weekend, and the four of us remained, sprawled around the fire. Sam sat cross-legged on the floor, leaning against the couch where Jules lounged, her legs draped over the armrest. Eva was mirroring Jules on the opposite couch, her feet resting comfortably in my lap.

There was nowhere to be, no deadlines, no distractions--just warmth, wine, and the people I loved most in the world.

I glanced up and caught Sam watching me over the rim of her wine glass. That glint in her eye was all too familiar. It meant she was about to say something ridiculous--something outrageous. The kind of thing that usually meant I'd have to defend someone soon.

Instead, she just said, "Will, Jules and I want a baby." She tipped her glass toward me like it was the most casual request in the world. "And we want you to be the father."

She might as well have asked me to pass the remote.

I blinked at her, sure I'd misheard--or misunderstood. But Sam went on, calm and steady. Like she was ordering dessert.

"Not adoption. Not a donor. I want a child that's part of me and part of Jules. And you're my twin--same DNA, same blood. It makes sense, doesn't it?"

I looked to Jules. She'd sat up a little straighter, one hand resting on Sam's shoulder.

Her face was unreadable--but not surprised.

Then I turned to Eva, who was watching me with curiosity, a smile tugging at the corner of her lips.

"I thought we were talking about taking a cruise to get out of the cold," I said, laughing nervously. "Did I miss a bunch of steps?"

"Will, it's not a joke," Sam said. "We've been thinking about this for a while. We want a child. And we want it to come from someone we know. Someone we trust. Someone we love."

Eva slid her feet from my lap and moved closer, pressing her hip against mine. She placed a hand on my knee, her voice soft and amused. "And you want to do this the... traditional way? No turkey basters? No clinics?"

Sam shrugged. "Nope. Just good old-fashioned P-in-V fucking. Feels more natural. Simpler. More connected."

Ever the subtle one, my sister.

I opened my mouth, not even sure what I meant to say--but Eva beat me to it.

"Okay," she said.

I turned to her, stunned. "What?!"

She looked at me, then at Sam. "I said okay. I won't get in the way if you want to sleep with Jules to get her pregnant."

I looked at the three of them, waiting for someone to crack--someone to say gotcha. But no one did. They just watched me, calm and serious.

Then Eva added, "I have a condition, though. If you get to sleep with Jules... then I get to sleep with Sam. Seems only fair."

The silence that followed wasn't awkward. It was electric.

We all knew I'd already said yes by not saying no.

Sam tilted her head, considering. Then she looked at Jules, who gave the smallest nod. Sam grinned--slow and wicked. "Deal," she said.

I let out a breath I hadn't realized I was holding and stared at the three of them. My head swam with disbelief--and something darker, heavier, warmer--curling low in my stomach.

In that moment, I realized we hadn't just crossed a line from safe and normal into something else entirely.

We didn't just cross it.

We set it on fire.

I sat back down and downed what wine was left in my glass. I looked up at the girls and said, "I'm going to need a minute with this." and I walked out to the back patio, pulling the door closed behind me.

/////

I'm not sure if I was out there for 5 minutes or 50, but I stared out at the moon and stars and waited for my brain to reboot. I didn't turn around when I heard the sliding door open and close behind me, just took the glass of bourbon she balanced on the rail between us and sipped while Eva leaned her head on my shoulder.

"Sorry, I had to just make sure the world was still spinning." I said.

She smiled, soft but with heat behind her eyes, "Is it?"

"Barely"

I sipped my bourbon and leaned on the rail next to her. Both of us staring out into the dark yard. The silence stretched for a beat, then two.

"I can't believe you said yes," I said, half turning my head to watch her reaction, "I expected confusions, maybe a "let's talk about this tomorrow without the wine".

Not.... whatever just happened"

She turned to face me, arms folded across her chest, "Because I said you could sleep with Jules?"

"Because you said it like it was no big deal, like it was one of them borrowing a pair of shoes."

Eva looked down and inhaled then looked back at me, her expression serious but not hard. "I didn't say it wasn't a big deal. I said I was ok with it. There's a difference."

I exhaled slowly, "This is... insane right?"

"Of course it's insane," she said laughing. "But not in a bad way, not in a dangerous way. It's just.... Honest. Real. Complicated... like all of the best things."

I studied her face, looking for cracks, doubts, anything that would make me call the whole thing off. "And the part where you want to sleep with my sister? That's not weird?"

Eva smiled again, a little blush coloring her cheeks, "Will, your sister is hot. Objectively. Subjectively. And she knows it, too. And so does everyone else. She's been flirting with me since you and I got together, you just never noticed."

I blinked, shaking my head, "Sam's been - what?"

"Oh yeah," Eva said. "Subtle stuff, you wouldn't catch it unless you were looking for it. But I was. Because she's Sam. And because I was curious. I've heard them through walls before too, you know."

"Jesus" I muttered, laughing in disbelief.

"You're surprised?"

"Kind of, this is a whole different level of.... whatever this is."

Eva set down her glass and stepped up close to me, pulling my arms around her.

"Will I love you. That's not in question. But sex with someone we already love - people we trust, people we share our lives with? It's not cheating. It's not betrayal. It's.... Something different."

There was a pause, I could feel her heart beating in her chest and her breathing slow and steady.

"It doesn't feel like jealousy?" I asked, kissing the top of her head.

"Strangely...... no. It feels like a door we've never looked behind. Not scary. Not wrong. Just new."

I nodded slowly, letting that settle in.

We stood there wrapped in each other for a few minutes before Jules stepped through the door behind us, a blanket draped over her shoulders and a mug of something warm in her hand. She looked at us, no judgement in her eyes - just curiosity.

"Hey," she said softly.

Eva turned, putting her back against my chest, my arms still around her. "Hey."

Jules leaned against the doorframe, her expression calm and inscrutable.

"I wanted to make sure you two had a chance to talk. I know this is... a lot."

"You could say that," I muttered.

Jules glanced over her shoulder and then pulled the door closed behind her, stepping closer to us. "Can I say something?"

"Please," Eva said, nodding.

Jules looked at me first. "Will, I know this feels crazy. But it's not coming from impulsiveness or drunkenness or anything. We've talked about this for a long time."

"And this?" I asked, motioning to Eva and pointing into the house. "All of it?"

She nodded. "We want a child. A family. But Sam didn't get that ability from the womb with you. So we have to find a different way. And we want it to come from love. Not just genetics or biology - love. So that means involving people we already trust in our lives. That means you."

I watched her, the way her eyes shone when she said it, the way her words didn't feel rehearsed, just real..... Grounded.

"So, is this just sex?" I asked quietly.

Jules smiled - not with amusement, but something softer. "It can be. Or it can be more. But whatever it is, it's about connection. And trust. I'm guessing we won't know until we get there. But if it didn't come from love, I'd never ask."

She touched Eva's arm, then mine, light as a feather. "None of this has to happen. But if it does it isn't about ownership, or permission or keeping score. It took me a long time to convince Sam to ask, but I'll be the first to shut it down if I thought any of the four of us would be hurt. It's about choosing to be open with the people we love. The people who matter."

She turned and went back inside, leaving only the scent of hot chocolate in her wake.

I stared at the sliding door into the house, heart pounding for reasons I couldn't sort out much less name.

Eva nudged me gently with her elbow, "You okay?"

"I don't know," I said honestly. "If we do this, you and me, it won't be the same again. No matter who it was, but especially because it's Sam and Jules....."

She reached up on her toes and turned my head so she could kiss me. "I trust you. I love you. I know that this is a gift for them, and no one else can give it. So if you want to, I'm with you. But if you don't, that's fine too and nothing changes."

"That's where you're wrong, it's already changed just by Sam asking." I kissed her lightly. "But you're right about the rest, it isn't about me and Jules or anything else."

Eva's lit back up with the mischief that I fell in love with 3 years ago, "You're just worried I'm going to like sex with your sister more than you. Come on back inside..." as she pulled me back in from the cold.

/////

The four of us found ourselves in the living room again, this time with the knowledge of what we were about to agree to. The flicker from the fireplace reflected in both Jules' and Sam's eyes as Eva and I sat on the loveseat across from them. My sister and her wife were curled together on the couch like we had seen a thousand times before. There was an air to the room - not tension exactly, but anticipation thick enough to chew on.

Sam was the first to speak, "So, I figured we better talk about the "how" of everything here. Since, y'know, we can't exactly wing this."

"Well, Sam, first Will has to stick his...." Eva started before giggling and dodging the throw pillow tossed from the other side. We all laughed, the tension broken and our natural rhythms back.

"No seriously, I agree. Where do we even start with this?" Eva asked as she pulled her legs up to sit cross legged on the couch.

Jules leaned forward, taking command like this was one of her projects at work, "First question - how many tries are we talking about?"

"I mean, hopefully just one," I said, trying to sound casual but already feeling out of my depth.

Sam arched a brow. "Wishful thinking. It could take a few cycles. Timing, biology, stress levels.... We don't want to rush it or put pressure on anyone."

Eva patted my knee, "So we try during her fertile window each month?"

"We?" I whispered to her getting an eye roll in return.

"Exactly," Jules said. "I'd track my ovulation. Then when the timing's right, Will and I... connect."

Sam smirked, "Connect. Right. Love that."

I shot her a look. "I'm trying to be serious about this."

"But it's adorable when you're flustered," Eva teased sliding her hand up from my knee. Just enough pressure to let me know she noticed the growing tension under my jeans.

Jules sipped her wine. "Also on the same note - do we want it to be just.... Once per window? Or a few days in a row."

Sam cut in, leaning back and putting her arm around Jules, "I vote for multiple tries. More natural. Less mechanical."

Evan made an agreeable noise. "I agree. Less stress if we're not pinning all our hopes on one night."

"Don't the two of us doing the actual 'connecting' get a vote?" I asked, looking to Jules to speak up with me.

"No silly boy, let the girls sort this out," Eva said with a kiss on my cheek. "Of course you do but do you disagree yet?"

"Well no..."

Sam took back over, "Ok so there's some detail missing. Is this just a 'wham, bam, thank you ma'am' and then Will leaves or is there more to it?"

I glanced at Jules and was pretty sure I saw a flush to her cheeks that wasn't there before. "I mean that's not my usual way to do things......."

Eva agreed, "Yes, if you want it to be, how did you say it? "More natural. Less mechanical." it can't just be a quick pump and dump then leave." She powered on ignoring the wave of awkwardness that was my fiancée and sister discussing me like a prize stud horse. "If this is about love, then I think Jules needs to get the full Will experience."

All three of us looked at my fiancée with various flavors of shock on our faces.

"What?" She explained, "I want this to be as successful as you, but there is no reason for everyone to enjoy themselves too."

I cleared my throat. "Okay, so what about... where?"

Sam and Jules exchanged a look. Jules answered calm and matter of fact. "Here at our place, our bed. It's where I feel comfortable. Where we feel safe."

"And where would you be?" Eva asked Sam, "Here?"

"I don't think I'm ready to see my brother fucking my wife, so probably not. But I do have your condition to fulfill so I imagine I can distract myself with you...." Sam trailed off showing a surprising level of timidness.

"Umm, yeah that would work." Eva answered in a way that I wasn't certain that she'd been caught out bluffing.

The room grew quiet for a long moment. Just the fire, the clink of a glass, the sound of four people breathing a little faster than they had five minutes ago.

Eva shifted toward me, eyes full of heat, "I think we've covered logistics for now."

Sam nodded, her hand sliding up Jules's thigh, "Yeah... I think it's time we took a break."

Jules glanced up at her with that same smile I remembered from that first night in college - the one that made you feel like gravity had shifted.

"Pick this back up tomorrow?" she offered, already standing and smoothing her skirt down and pulling Sam to her feet.

I barely registered my nod before they slipped away toward their bedroom, hands already wandering.

Eva's lips were at my ear the second the door clicked shut behind them. "Guest room, Now."

"Eva...."

"I've been wet since half way through that conversation, " she growled, low and feral. "All I could think about was your sister's mouth. The way she talks, the way she kisses Jules. The way Jules looked at you like she already knew how you tase. I need you. Right. Now."
