Romantic Sex Story: Chapter 12 - Jim and Aimee have a chance meeting over a jar of peanut butter. In the beginning, he's a married father, she's a college student. That chance meeting in a grocery store, and the coincidence that follows, will change their lives (and others' lives)! I brought this story back to life in late 2025, more than 20 years after I first started writing it.

The house had slipped back into its weekday routine, but it hummed a little differently now. Softer around the edges. Like someone had adjusted the lighting -- not enough to notice at first glance, but enough that I kept re-orienting to it.
It was a Tuesday night. We were done with dinner and the kids were drifting between half-finished Lego builds and the tail end of a cartoon. I was at the sink rinsing plates when Aimee wandered in, padding barefoot across the tile, a loose sweater sliding off one shoulder.
She offered to dry. I handed her a plate. Our fingers brushed. That didn’t used to feel like anything. Now it felt ... important. Meaningful.
Beth came in behind her a moment later, tired from a nine-hour day but looking lighter than she had in weeks. She stepped into Aimee’s space without hesitation, reaching past her for the dish towel, and the side of her hand grazed Aimee’s hip. A small touch. A casual one. But casual in that ... new way -- the kind that carried all the aftershocks of last weekend.
Aimee didn’t flinch. She just looked over at Beth with this little half-smile -- warm, quiet, private.
I didn’t make a show of watching them, but I saw it all reflected faintly in the microwave door: the two of them standing close, moving around each other like they’d already rehearsed it.
No awkwardness. Just a new thread running through the room.
Ethan barreled in asking if he could have “just one more cookie,” which bought me a second to breathe. It grounded me, honestly -- the normalcy. The kids’ orbit hadn’t shifted at all. They just saw Aimee as Aimee, the way they always had.
Later, after bedtime, the three of us ended up on the couch. Aimee tucked into the corner, Beth leaning against my shoulder, my arm draped along the back of the sofa where it could reach both of them without drawing attention to itself. Nothing happened -- that was the point. We just sat there in the low light, some forgettable show playing in the background, all of us warm and quiet and comfortable.
There was no recreating the intensity of that first night. None of us were trying. This felt like the part where you see if it holds in daylight, in real life, with laundry baskets and grocery lists and homework folders.
And it did.
The next night, they met in Aimee’s bedroom for the first time.
Aimee perched on the edge of her bed as if she wasn’t sure whether she was hosting company or accidentally summoning it. Her room smelled faintly of her shampoo -- citrus with a warm undertone -- and everything felt closer in here. The small lamp. The narrow bed. The three of them trying to fit into a space that barely fit two.
Jim sat beside Aimee first, their shoulders brushing. Beth settled on the other side, the mattress dipping under her weight and nudging all three of them closer until their knees touched in a way that felt both accidental and completely intentional.
Aimee let out a quiet, breathy laugh -- the sound of someone thrilled and shy at the same time.
“We’re really doing this,” she whispered.
Jim smiled at her. “Yeah,” he murmured. “We are.”
Beth reached for Aimee’s hand because Aimee looked like she didn’t know where to put it. Her fingers were cool at first, then warmed quickly as they wrapped around Beth’s. Aimee looked down at their joined hands for a moment, as if imprinting it in her memory, and when she lifted her gaze her eyes were bright.
The first kiss was barely more than a brush. Aimee leaned tentatively toward Beth -- that tiny tilt of her head she always had when she was nervous -- and Beth met her halfway. Aimee’s lips were soft and cautious, tasting faintly of the peppermint tea she’d had with dinner.
Jim watched them with a softened expression Beth felt even without looking directly at him.
Aimee pulled back with a shaky exhale -- a happy one -- and Jim slid a hand to the small of her back, his fingers warm through the cotton of her shirt. She leaned into him instinctively, like she’d been waiting for that touch all night.
He kissed her next, a little surer, though still gentle. Aimee’s hand curled against his thigh for balance, and Beth could feel the warmth rising through her body even from a few inches away.
When they parted, Aimee turned toward Beth again, cheeks flushed, emboldened now. She lifted a hand to Beth’s jaw and kissed her deeper this time, the kiss lengthening, warming, her thumb brushing Beth’s cheekbone in a way that made Beth’s breath catch.
Jim shifted closer, closing the triangle between them. Knees and arms and hips touched in ways that weren’t planned but felt inevitable. Every movement brought a new point of contact -- someone’s shoulder grazing someone’s arm, a knee nudging a thigh, a breath brushing a neck.
Aimee ended up nestled between them, her back against Jim’s chest, her legs angled toward Beth. Jim’s arms slid loosely around her waist; Beth rested a hand on her thigh, just above her knee, feeling the faint tremor of adrenaline under her skin.
Aimee looked at the two of them like she couldn’t quite believe she was being held this way -- by two people who wanted her, who cared for her, who cared for each other.
“This feels ... different,” she murmured.
It did. It felt like discovery rather than chaos -- the beginning of something new again.
Jim’s hand slid up the back of Aimee’s shirt while Beth’s slid into the front, making Aimee moan with pleasure. Eventually, it was easier just to remove it, and they giggled softly as they worked on each other’s clothes, a piece at a time.
When all three were bare, they eased back onto Aimee’s bed, the narrowness forcing them together closely. None of them minded.
Aimee and Beth faced each other, kissing deeply, their nipples erect and touching. They sighed softly into the kisses, hands roaming over each other slowly. Jim slid in behind Aimee, and she groaned when she felt his mostly-erect cock nestle into the crack of her ass. He pressed up against her tightly from behind, kissing her neck. His hands roamed up and down her side, touching her ribcage, her hips, and sliding over to gently stroke Beth’s body as well.
His erection stiffened as he pushed it against Aimee’s smooth ass. He was kissing along Aimee’s jawline when he felt eyes on him, and he looked up to meet his wife’s gaze. Her eyes flicked downwards, towards Aimee’s thighs. “Put it in her,” she mouthed silently.
“Like this?” he mouthed back, and Beth nodded excitedly, her eyes shining.
Jim slid one hand down over Aimee’s cheeks and between her thighs. The side of his hand brushed against her pussy -- already hot, already wet -- and she moaned with pleasure.
He slipped that hand further between her thighs and lifted her top leg. Beth helped, pulling Aimee’s leg over to rest it on her own, spreading Aimee’s thighs, opening up her center. Beth watched excitedly as Jim fisted his cock and brought the head to Aimee’s opening, and the younger girl moaned a little too loudly as she figured out what was happening.
Beth moved her mouth over Aimee’s, kissing her to keep her quiet, but her eyes stayed focused further down the bed. Jim flexed his hips and pushed deeper into Aimee, his cock slick with her excitement. This time, it was Jim who had to muffle his own voice, burying his face into Aimee’s neck, grunting an “oh my god” into her skin.
Aimee shivered with pleasure as she felt Jim sliding into her, as she felt Beth’s mouth on her own, Beth’s hands all over her body, Beth’s tits pressing against hers, Jim’s breath hot and excited against her neck. Her whole body felt tingling, excited, alive.
Beth moved a hand to Aimee’s chest and stroked her nipples as she watched her husband -- her husband! -- push his cock all the way inside Aimee. Beth wasn’t jealous, wasn’t mad, wasn’t worried -- wasn’t anything but excited. She could feel her own pussy radiating with heat, the wetness seeping from between her thighs. She nearly jumped off the bed when she felt Aimee’s thin fingers slip between those thighs, and now it was her turn to moan into their kiss.
They stayed like this, the positioning somewhat awkward but too hot to change. Jim thrust in and out of Aimee’s pussy from behind her, while the women touched and kissed each other. Every so often Beth would break the kiss with Aimee and lean over her to kiss Jim, their tongues tangling as Aimee watched, gasping with pleasure. Beth reached across their bodies and grabbed at Jim’s ass, pulling him into Aimee. She moaned with her own pleasure as every stroke Jim made into Aimee’s body pushed Aimee’s pelvis into her own.
They fucked like that for a few more minutes, trading hot kisses, trying to keep their voices soft and quiet and low-pitched. Beth heard Jim’s moans get a little more chaotic, felt his hips pushing against Aimee a bit faster, and she knew he was getting close. She kissed Aimee even harder and grabbed at Jim’s ass even tighter. Her pussy throbbed as she felt both of them shudder with their climaxes, Aimee burying her face and voice in Beth’s neck, Jim doing the same at the back of Aimee’s neck as he emptied himself into her.
Jim kept thrusting into Aimee for a few more minutes, then slowly withdrew himself, their combined fluids sliding out of her onto the towel beneath them -- they’d learned important lessons from their first night! He slid his tongue around Aimee’s ear, making her giggle, and then moved his lips to her ear. He whispered something to her, so softly that Beth -- from a few inches away -- couldn’t hear it. Whatever it was, Aimee nodded immediately, her smile widening.
Without warning, the two of them suddenly put their hands all over Beth, guiding her to the center of the bed. Aimee kissed her hard and deep, and then moved aside so Jim could do the same. Then, as if they planned it, they started kissing down her body in unison.
Jim on the left, Aimee on the right, they explored her body with their lips and tongue. Kissing down her neck, over her shoulders, onto her chest. Their mouths danced all over her tits -- not just her nipples, but the top slopes, the sides, the undersides. They moved lower, their tongues dancing in her belly button, making all three of them giggle.
Eventually, they found their way to her pussy, which was desperate for their attention at this point. Aimee and Jim furiously made out with each other, and with her pussy. Their tongues were everywhere -- up and down her lips on both sides, dancing into her entrance, tangling with each other on her clit. Her hips moved up off the bed of their own accord, and she clutched at their heads as they ate her. She felt Jim’s hand slip underneath her, palming her ass, pulling her pussy tighter to their faces.
When her voice started to get a little louder, Jim tossed a pillow in her direction and she let go of their hair, clutching the pillow over her mouth. Jim and Aimee ate her to a screaming orgasm, muffled only by the pillow, her pussy clenching and releasing as the waves of pleasure rippled through her.
When she looked up, the fire in her belly thrummed again as she watched them kiss each other, deeply. She watched as Aimee licked Jim’s cheeks, his beard, his nose, and then he returned the favor, licking her chin, her neck, her face, before they kissed each other again.
They’re tasting ME on each other, Beth thought with wonder. That is so fucking hot. All of this is just so fucking hot.
Eventually, the two of them moved up the bed and slid up against her, cuddling her on both sides. She could feel Jim’s cock on her right, still hot against her hip. On her left hip, Aimee’s pussy, maybe even hotter, nestled against her. Her mind swam with the wonder of it all, her body in the pleasant post-orgasm afterglow.
They stayed like that for a while, trading soft kisses and small touches, moving together without urgency. Warmth, closeness, a slow unfolding of trust -- nothing rushed, nothing showy, just the kind of quiet intimacy that only comes when no one is trying to prove anything.
Eventually, when the room went still and Aimee’s eyes grew heavy, Jim leaned over and kissed her shoulder lightly.
“We should let you sleep,” he whispered.
Reluctantly, they eased back. Another round of gentle kisses, one last warm squeeze of her hand, and then Beth and Jim redressed and slipped out of the room like teenagers sneaking home late.
Aimee watched them go with a sleepy smile, pulling her blanket up around her shoulders.
Back in their own room, Beth could still feel the impression of Aimee’s hand in hers -- and the way the three of them had fit together in that too-small bed, imperfect and beautiful, learning each other by touch.
Saturday morning, Beth reached the top of the stairs with a basket of folded towels balanced on her hip, half-distracted by the list of chores still waiting downstairs. She wasn’t expecting company in the hallway -- which is why she stopped short when Aimee stepped out of her room at that exact moment.
Aimee wore nothing but a short gray robe, loosely tied, her legs smooth and bare, her hair mussed from sleep.
The robe slipped open a careless inch as Aimee pulled her door shut behind her, and Beth couldn’t help glancing into the gap.
“Oh--hey,” Aimee said, startled but smiling, cheeks warming. “Didn’t think anyone was up here.”
Beth’s fingers tightened around the basket. “I was just ... putting these away.”
Aimee took a few unhurried steps down the hallway toward the bathroom, which meant Beth had to step aside to let her pass. Except Aimee didn’t pass. Not immediately.
She stopped close enough that Beth could feel the heat coming off her. Close enough that the faint cotton smell of the robe -- faint detergent, faint Aimee -- wrapped around them both.
“Good morning,” Aimee said, softer this time.
The robe slipped again at the collar, revealing just a whisper more of the skin beneath. Beth’s breath stuttered. Aimee noticed. Of course she did. She bit her lip -- shy, pleased -- and stepped even closer, hand lifting lightly to Beth’s elbow.
Beth swallowed. “You headed to the shower?”
Aimee nodded, a small tilt of her head, strands of hair falling forward. “Yeah. Unless you ... need something in there first?”
The question wasn’t innocent, not with the way her eyes moved -- slow, deliberate, dipping to Beth’s mouth for a single heartbeat.
Beth’s pulse jumped.
She didn’t step back. Aimee didn’t either.
Instead, Aimee leaned in and pressed a soft, lingering kiss to Beth’s lips -- a morning kiss, unhurried, full of promise. It wasn’t deep. It didn’t have to be. It lit up every nerve in Beth’s body anyway.
“See you shortly,” Aimee murmured, voice warm against Beth’s cheek.
Then she turned and padded the few steps to the bathroom, pushing the door almost closed behind her, soundless, not fully latched, Beth noticed. A choice.
Beth stood there for a moment, stunned, heartbeat too fast, hands shaking around the laundry basket. And then she slid the basket into her room and quickly went downstairs.
Jim was cutting strawberries for the kids when she came into the kitchen. He glanced up once -- one look was all he needed.
“What happened?” he asked, a quiet laugh under the words.
Beth leaned close, lowering her voice. “She was in the hallway. In her robe. And she...” Beth exhaled sharply. “Jim, I really wanted to get in the shower with her.”
Jim didn’t blink, didn’t tease, didn’t second-guess. He just set the knife down and stepped close.
“So why don’t you?” he said quietly. “I’ve got the kids.”
Beth blinked at him -- a wave of gratitude hitting so fast it almost hurt. Jim wasn’t performing sainthood, wasn’t sacrificing anything. He meant it. Simple. Generous. Steady.
She kissed him -- not a thank-you, not a duty, but something deep and warm and grateful. His hands held her waist, firm and steady, grounding her even as her pulse jumped.
When she pulled back, he nodded toward the stairs.
“Go,” he said, soft and sure. “She’ll want you.”
Beth didn’t trust her voice. She just pressed her palm once to his chest -- a silent promise -- and headed back up the stairs, heart kicking hard enough that she felt it in her fingertips.
Back upstairs, the bathroom door was still unlatched -- that same deliberate choice, like Aimee was hoping and not hoping at the same time.
Beth lifted her hand, hesitated only a moment, and slipped inside.
The shower was running now, steam curling faintly above the curtain rod. Aimee’s robe lay folded -- or dropped, more like -- across the closed toilet lid. Through the curtain Beth could see her outline: small, delicate, blurred by water.
Beth let her own clothes fall in a quiet series of soft sounds -- a shirt brushing tile, a zipper lowered, the whisper of fabric. She moved slowly, partly to keep quiet, partly because her hands weren’t steady.
She eased the shower curtain back just an inch.
Aimee turned at the sound, eyes wide, mouth falling open for half a beat -- surprise, then blooming warmth, then something unmistakably hungry lighting up her whole face.
“Bethhhhhh,” she breathed.
Not a question. Not shock. More like relief threaded with excitement.
Beth stepped in, letting the warm water hit her shoulders, and Aimee reached for her immediately -- hands at her waist, drawing her completely under the spray, pulling her close as a smile broke across her face.
“You came,” Aimee whispered, breathless, delighted.
Beth cupped Aimee’s face, lifting her chin.
“Of course I did.”
Their mouths met again -- this time not tentative, not hallway-soft. Warmer. Deeper. Aimee pressed close, their breasts crushing together, water running over both of them, her fingers curling at Beth’s hips like she’d been waiting forever for this exact moment.
The steam rose around them, blurring edges, softening everything but the heat between their bodies.
Beth lowered her face to Aimee’s and they kissed deeply. Beth felt her nipples throb against Aimee’s chest, and she slid a hand over Aimee’s ass, pulling her closer. Aimee moaned as she did so, her body relaxing into Beth’s as they kissed.
Beth’s heart pounded when she felt Aimee’s hand on her belly, and then it slipped lower, pushing through her pubes. “Oh Aimee, oh yes,” she said, spreading her thighs. “What a good idea,” she continued, placing her own hand on Aimee’s abdomen and copying her movements.
“Oh! Oh yes Beth!” Aimee exclaimed, as the two women positioned themselves to give them room for what they both desperately wanted. They continued to kiss as they fingered each other, Beth moaning with pleasure as Aimee’s slim fingers moved all over her lips. Her heart skipped a beat every time one of Aimee’s soft fingertips brushed over her throbbing clit.
Meanwhile, she was doing the same, her fingers sliding over Aimee’s wet and warm folds. She felt the younger woman start as Beth curled her middle finger and slid it inside Aimee, just an inch or so.
“Fuck, Beth,” Aimee said, breaking their kiss and burying her face in Beth’s shoulder. “Oh god, that feels so good. So damn good.”
As Beth pushed her finger slightly further inside Aimee, she felt Aimee doing the same with her, one finger sliding just inside her opening. “Oh yes, Aimee, fuck yes, let’s do this together. Finger fuck me while I finger fuck you.”
“Oh!” Aimee said, as she pushed further into Beth. “Oh yes! This is so fucking hot, Beth, oh my god this is so hot.”
Beth moaned in agreement as she kept sliding her finger in and out of Aimee. Aimee pulled her face back down into a kiss, but then Beth broke it in shock as she felt Aimee slide a second finger inside to join the first. “Oh god Aimee, oh god!”
Aimee giggled. “I figured you needed a second finger, you’re so used to that thick cock,” she said, now pumping two fingers in and out of Beth’s tightness.
Beth’s pussy throbbed as she heard the dirty talk from Aimee, so unexpected. “Fuck me, Aimee,” she exclaimed. “I mean, keep fucking me. Holy shit.”
“But,” she continued, “You’re getting pretty used to that cock too,” she said, sliding her pointer finger into Aimee. As Aimee gasped, Beth felt a fresh gush of moisture slide over her fingers.
“Oh fuck -- oh fuck Beth, yes, it’s so good, oh my god.”
They kept fingering each other, mimicking each other’s movements. When Beth moved her thumb to Aimee’s clit and started massaging it, Aimee did the same to hers. That kicked the feelings into overdrive for both of them, and they started gasping louder as each of their orgasms slammed over them, Beth only 30 seconds or so ahead of Aimee.
Silently, they slipped their fingers out of each other and simply held each other, embracing under the water, their slick bodies pressed against each other tightly.
The water was starting to cool before either of them moved. Beth finally reached past Aimee to turn it off, their bodies still pressed together in the last warm currents of steam.
Aimee leaned her forehead against Beth’s collarbone, breathing in a slow, shaky rhythm.
“Okay,” she whispered, smiling against her skin, “that was ... so good.”
Beth let out a breath that was more laugh than exhale. “Yeah,” she echoed.
They separated reluctantly. Not far -- just enough to breathe, enough for Beth to tug a towel from the rack and wrap it around Aimee’s shoulders. Aimee’s hands slid along Beth’s hips on their way down, a barely-there touch that said she wasn’t ready to let go.
Beth dried herself and then dressed clumsily, fingers shaking just a little, while Aimee slipped back into her robe. She cinched it tighter this time, tying the knot properly -- though the flush on her cheeks betrayed the effort to look composed.
Aimee glanced toward the door, suddenly shy. “Do you think the kids are--”
Beth cracked the bathroom door just an inch and peeked out.
Empty hallway. Blessedly quiet.
She turned back, smiling. “Clear.”
Aimee let out a breath of relief, then paused, biting her lip. “Does Jim ... know? I mean--did you tell him you were coming up here?”
Beth’s smile widened, warm and a little wicked. “It was his idea.”
Aimee blinked, startled delight blooming across her face. “Seriously?”
Beth nodded. “He said he had the kids. And that I should go.”
Aimee swayed a little at that, something tender flickering behind her eyes. “That’s ... really sweet,” she murmured. “And also very, very hot.”
Beth felt a blush rise up her neck. “Yeah. It was. Might be something one of us should thank him for, sometime,” she said, winking.
They shared one more quick kiss -- soft, secret, stolen -- before Beth stepped out first, wrapped in the leftover heat of the room. Aimee followed a few seconds later, pausing to check the hallway again before slipping quietly back into her bedroom.
Beth headed downstairs, hair still damp, trying to ease her face into something resembling normal.
Jim was in the kitchen loading dishes into the dishwasher, the kids on their iPads in the family room. He looked at her when she entered -- raising one eyebrow in her direction, the corner of his mouth lifting.
Beth blushed instantly. She wiggled her fingers at him in a tiny, triumphant little wave -- equal parts don’t ask and you know exactly what happened.
Jim’s smile deepened. That was all either of them needed to say.
