Jenny Mortimer - A Little bit of Frank, David & Jenny

At 15, Jenny's world is reshaped when her brother Frank and cousin David claim her together, turning a hot tub into a playground of forbidden, shared desire.

FRANK – THE BROTHER
The movie theater was dark, the seats plush, the air thick with the scent of buttered popcorn and teenage sweat. Frank and Tanya sat side by side, their knees brushing, their hands resting on the armrests, inches apart. Frank’s hand twitched, his fingers curling and uncurling, his breath coming in short, sharp bursts. Tanya’s lips were parted, her eyes fixed on the screen, her chest rising and falling with each breath. She wore a black dress—short, tight, the kind that hugged her curves and made Frank’s cock hard in his jeans. Her hair was in neat braids, a simple choker biting into the smooth skin of her throat. In the flickering light from the screen, her face was angelic, though her dark eyes held something he couldn’t name.
The movie was terrible—a romantic comedy, full of clichés and bad jokes. But Frank didn’t care. He was watching Tanya. The way her lips moved when she laughed, the way her eyes flicked to him when she thought he wasn’t looking, the way her own fingers twitched, her nails painted a stark red.
And then, during a particularly bad joke, Tanya turned to him, her eyes locking onto his. Her lips parted, her breath warm against his skin. “You’re not laughing,” she whispered, her voice low and thick with something he couldn’t name.
“I’m not,” he said, his voice rough, his eyes fixed on her lips.
She leaned in, her body pressing against his, her lips brushing his. It was a soft, tentative kiss—just lips, no tongue, no pressure. But it was enough. Frank’s cock twitched in his jeans, hard and instant. Tanya’s body trembled, a soft gasp escaping her. She pulled back, her eyes wide, her cheeks flushed.
“Was that good?” she whispered, her voice thick with need.
“Perfect,” Frank said, his voice rough as he reached out, his fingers brushing against her cheek. “You are so beautiful.”
He kissed her again—harder, deeper, his tongue probing her lips, his fingers tangling in her hair. His strong fingers slipped between her legs, rubbing her. She moaned into their kiss, a low, breathy sound she couldn’t stop. Her body trembled, her hips jerking against his hand, her fingers digging into his shirt. She pulled back, her eyes wide, her lips parted.
“Wow,” she whispered. “That feels incredible—”
“I’m glad,” Frank said, his voice rough. His hand moved away, sliding down her side, his fingers brushing against her hip.
She smiled, a slow, knowing curve of her lips. They kissed passionately again.
They dated for a few weeks—the usual: movies, dinners, walks in the park. But something was off for Tanya. She couldn’t put her finger on it, but there was something missing between them, a feeling no kiss could bridge. Frank was sweet, attentive, kind—but he wasn’t the one. He wasn’t the one who made her body tremble, her breath catch, just by being in the room. He wasn’t the one who made her want to cream herself every time he kissed her.
Then, one night after a movie, they were in his car, parked in the driveway, the engine off. The air was thick with the scent of sweat and arousal. Frank’s hand was on her thigh, his fingers brushing against her skin, his cock hard in his jeans. Tanya’s hand could feel his hardness through the denim. He moaned. She decided to unzip him.
She reached in and wrapped her fingers around the thick, hot shaft, her thumb stroking the head, smearing pre-cum over the tip. He moaned, a deep sound escaping his lips.
“Do you want me to stop?” she whispered.
“No,” Frank said, his voice rough, his hips jerking. “Don’t stop.”
She stroked him harder, her fingers moving faster, her thumb rubbing the head, her nails scraping against his skin. His body trembled, his hips jerking, his cock throbbing in her hand. He was getting close, the pressure building to an unbearable peak.
“Tanya… I’m gonna…” he managed to gasp, his warning lost in a choked groan.
She didn’t stop. If anything, her grip tightened, her strokes becoming more deliberate. With a final, shuddering thrust, he came, his cock pulsing as he shot cum over her hand and onto his own stomach. He collapsed back against the seat, his chest heaving, his mind a complete blank.
She pulled back slowly, her eyes wide as she looked at the mess on her fingers. A flicker of something—pride, maybe, or shock—crossed her face before she carefully wiped her hand on a discarded napkin from the glove compartment.
“That was great – thank you!” Frank said, his voice still rough. He wanted more. He wanted her. But she wasn’t ready.

On another occasion, they were watching a movie in the living room. Jenny watched them from the doorway, her body trembling, her breath coming in ragged gasps. She was jealous. She wasn’t sure why. She knew she wanted the attention Tanya was getting—from someone. She wanted hands on her body, lips on her skin, a tongue in her mouth. Watching Frank with Tanya made her ache.
And then she thought of David: her cousin, her first, her only. The one who had taken her virginity, the one who made her body tremble and her breath catch. She craved him, not just his body, but his touch, his voice, his presence. She was constantly wondering when he could visit again. She needed him. She needed his cock, his hands on her body, his lips on her skin. She didn’t know if she meant it. But she knew she wanted to.

DAVID – THE COUSIN
Movie night with Abby had always been our thing, a bubble of junk food and shared blankets where the rest of the world disappeared. But lately, that bubble felt different. She had just hit her teens, all sudden angles and a quiet curiosity that led to questions I had no business answering. Questions about her body, about boys, about the things she’d heard whispers of at school. I’d always deflected, changing the subject with a clumsy joke, feeling a hot flush of guilt. I was her brother, not her encyclopedia of perversion.
Tonight, though, the defenses were crumbling. She’d picked some brainless action flick, but it was laced with moments that were anything but. A steamy scene in a dark alley, the woman dropping to her knees as the camera panned away. Abby was riveted, her eyes wide, glued to the screen.
"Is she...?" she started, her voice a hushed whisper.
I tried to hold out. "It's just a movie, Abby."
"No, but for real," she insisted, turning to me, her expression so earnest it was disarming. "Is she really... putting his... you know... in her mouth?"
I sighed, the fight draining out of me. The cat was out of the bag, and I was the one holding the door. "Yeah," I mumbled, staring at the screen. "She is. It's called a blowjob. And... yeah, it feels amazing for a guy."
The words hung in the air between us, thick and undeniable. I expected her to blush, to laugh, to recoil. Instead, a slow, thoughtful smile spread across her face. And then she moved.
Her hand, warm and small, landed on my thigh. I froze, every muscle in my body locking up. I should have shoved it away. I should have stood up and declared movie night over. But her touch was electric, a current running straight to my groin. My body betrayed me, hardening instantly under the thin fabric of my sweatpants. Her eyes flickered down, a spark of triumph in them. She didn't hesitate. Her fingers slid up, tracing the rigid line of my erection through the cotton. My breath hitched. This was the point of no return, the moment I had to be the adult, the brother. But her hand felt so damn good, a forbidden pressure I craved more than I feared.
Before I could form a single coherent thought, her fingers dipped under the waistband of my sweats, past the elastic of my boxers. The skin-on-skin contact of her fingers wrapping around my shaft blew my mind. A choked gasp escaped my lips. She pulled me free, her eyes wide with a mixture of awe and clinical curiosity as she stared at my cock in the dim light of the TV.
Then she leaned down. The wet heat of her mouth engulfing the head of my cock was a shock so profound my vision went white. A soft, pleased hum vibrated against my most sensitive skin. She wasn't clumsy; she was exploring. Her lips sealed around me, her tongue swirling, and my hips bucked off the couch. Instinct took over. My hand flew to the back of her head, my fingers tangling in her hair, not pushing, just... holding on. I pressed down gently, and she took the cue, sinking lower, taking me deeper into her warm, willing mouth.
My little sister was blowing me. The thought was a lightning strike of pure taboo, a jolt of wrongness that was obliterated by the sheer, overwhelming pleasure.
"Don't stop," I croaked, the words barely a whisper.
She didn't. She found a rhythm, a perfect, torturous suction that built a pressure deep inside me. The wet sounds, the sight of her dark head bobbing in my lap, the incredible, illicit reality of it all—it was too much.
"I'm gonna... Abby, I'm close," I managed to warn her, a last-ditch effort at responsibility.
She just moaned and took me deeper, her hand cupping my balls. The orgasm ripped through me, a violent, shuddering release. I flooded her mouth, pulse after pulse, and she drank it all down, her throat working as she swallowed every last drop.
When I was spent, she popped back up, a triumphant, wickedly beautiful smile on her face. She licked her lips, a flick of her tongue that made my spent cock twitch, and then giggled. The sound was so innocent, so at odds with what she'd just done.
"Where the hell did you learn that?" I breathed, my mind a complete blank. I was elated, adoring her with a fierce, protective love, and horrified, sickened by my own utter failure to stop her.
Her face was close to mine, her sweet, youthful features illuminated by the screen. "I saw Emma give you one at the pool during your birthday party," she confessed, her voice still a whisper. "When you guys thought you were alone behind the changing shed. It... it made me wet, seeing that look on your face."
Her expression shifted, a flicker of uncertainty in her eyes. "Did I do it wrong? Are you angry at me?"
Angry? How could I be angry? I was a co-conspirator. A willing victim. I wasn't angry; I was overcome with a terrifying urge to reciprocate, to give her a fraction of the earth-shattering pleasure she'd just given me. She was still holding me, stroking my semi-hard cock with a slow, reflexive rhythm, as if memorizing the shape of me.
That's when we heard it. The soft click of the living room door handle turning.
Panic, pure and cold, seized me. I snatched the throw blanket from the back of the couch, whipping it over us just as Mom's head poked in. Her eyes scanned the room, a knowing, suspicious look that made my blood run cold.
"What are you guys doing?" she asked, her gaze lingering on us, huddled together under the blanket.
My face was a burning beacon of guilt. I knew I looked like I'd just seen a ghost. Or been caught with my dick out.
"Watching a movie!" Abby chirped, her voice perfectly normal. "An action one."
That seemed to piss Mom off even more. "David, I told you," she started, her tone shifting from suspicion to standard parental annoyance. It was a welcome distraction.
"Sorry," I mumbled. "It's PG-13."
The lie was pathetic, but it worked. Mom gave a final, disapproving sigh and turned to leave. But as she was halfway out the door, her eyes caught something. She saw Abby's hand emerge from under the blanket, pulling away from my lap. The way it moved, the angle of retreat—it was unmistakable. Her eyes widened, a flicker of horrified understanding dawning in them before she masked it with a tight, unreadable expression and pulled the door shut.
What the fuck? I could practically hear the thought screaming in my mom’s head.
The next morning, the verdict came down. No discussion, no accusation. Just a declaration from Mom, her voice brittle and strange.
"David," she said, not quite meeting my eyes. "Pack a bag. You're going to visit your aunt and uncle in Pennsylvania for a while."

TANYA
Hanging out at Frank’s house was a special kind of torture. He was my boyfriend, but I couldn't stop watching the way he was around Jenny. He had this easy, oblivious charm with her that made a knot of longing and jealousy tighten in my stomach. I hid a secret lust for her, a fire I had to constantly smother whenever she laughed at one of his stupid jokes.
One afternoon, while Jenny was out of the room, Frank nudged me, a smug little grin on his face. "You know," he confessed, his voice low, "Jenny's the one who gave me a strong tip on how to kiss. Changed everything."
A jolt went through me, sharp and hot. The image of Jenny, serious and intent, teaching Frank how to use his mouth was suddenly all I could think about. It wasn't about Frank; it was the idea of Jenny, her lips, her knowledge. It turned me on so much a sudden, telling warmth spread through my belly.
A few nights later, the tension finally snapped. We were in Frank's room, the door supposed to be shut. I was straddling his lap, my dress hiked up my thighs, kissing him with a desperate passion. The hard ridge of his jeans pressed against the thin lace of my panties, a delicious friction that was a poor substitute for what I really wanted. We were lost in it, a tangle of limbs and muffled breaths, when the door swung open.
Jenny popped her head in, assuming I’d already left. The look on her face was a masterpiece of shock. She saw us—saw me, grinding on my boyfriend's lap, his hands gripping my hips, our mouths fused together. But instead of scrambling away in shame, a thrill shot through me. I loved it. I loved being seen by her.
A slow, deliberate smile spread across my lips as I broke the kiss and turned to face her. "Come on in, Jenny," I purred, my voice husky. "We were just talking about you."
Frank looked like a deer in headlights, but I held Jenny’s gaze. "Frank was just telling me what a great kissing teacher you are."
For a second, she just stared, her expression unreadable. Then, something shifted. A challenge sparked in her eyes. She stepped into the room and closed the door softly behind her. She walked right up to me, her movements deliberate and fluid. Before I could process it, she took my face in her hands, her touch firm and confident. She kissed me.
It was nothing like kissing Frank. Her lips were soft but demanding, pressing against mine with an authority that made my head spin. A low hum started deep in my chest. Then, her tongue probed, tracing the seam of my lips, and I surrendered completely. I opened for her, and our tongues met. It was a test, and I was determined to pass. We went for it, a deep, exploratory kiss that tasted of mint and a raw, feminine power that left me breathless. A flood of heat washed over me, and I could feel myself getting instantly, intensely wet. All I could think about was exploring her, all of her. I wanted to know if her skin tasted as sweet as her mouth, if her hair was as soft as it looked, if she made that same little sighing sound when she was touched.
"Fuck yeah, you girls are hot!" Frank groaned from beneath me, his hands tightening on my hips, but he was a distant echo.
When Jenny finally pulled away, she was so close our noses almost touched. Her eyes burned into mine. "Don't leave the boy hanging," she whispered, her voice a low, intimate command that sent another shiver through me.
Then, just as smoothly as she’d entered, she turned and left the room, closing the door behind her and leaving me with a pounding heart and a very, very interested Frank.

A LITTLE BIT OF JENNY, FRANK AND DAVID
The water was warm, almost too warm, the kind of heat that seeped into your bones and made your muscles melt. Jenny stood in the center of the hot tub, her back to David, her hips swaying slightly, her small, pale ass just above the waterline. She was naked, her skin slick with sweat and water, her breasts small but perky, her nipples hard against her pale skin. Her hair was wet, plastered to her head, her braids hanging down her back. Her face was turned up to the sky, her lips parted, her breath coming in soft, shallow gasps.
David stood behind her, his cock hard and thick, jutting out from his body like a promise. He was naked, his body taut with arousal, his breath coming in short, sharp bursts. He reached out, his hands sliding over her hips, his fingers digging into her flesh as he pulled her back against him. She gasped, her body trembling as she pressed against his cock.
They were just settling into the bubbling water when Frank’s car pulled into the driveway with a frustrated squeal of tires. He slammed the door, his mood black. Tanya had done it again, leaving him simmering with a hard-on and a head full of empty promises. He knew his little sister should be home by now, but the house was dark. Then he saw it: the soft glow of lights from the pool house. A flicker of movement through the steam-fogged glass.
He went to investigate, his footsteps silent on the damp patio. The sound of giggles and low talking drifted out, mingling with the churning of the jets. He crept closer, peering through the glass doors. His breath caught in his throat. It was Jenny, and she was naked. His fifteen-year-old sister, a vision of smooth, lean curves and glistening skin, looked so hot it hurt to look. Then he saw David, his cousin, also naked, standing tall and proud in front of her, his cock hard and jutting from his body like an offering.
Frank approached, his own frustration forgotten, replaced by a raw, voyeuristic hunger. He watched through the glass as Jenny stood to face David, the height difference between them stark and incredibly erotic. She took his cock in her hand, her fingers circling his girth, and began to stroke him with a slow, sure rhythm. They kissed, a deep, possessive kiss that made Frank’s own cock ache.
David’s head turned, his eyes catching a glimmer of movement at the door. Panic seized him. If his aunt or uncle caught him, they’d kill him. His uncle was staunchly conservative; incest would not fly in this house. But then he saw it was Frank. And Frank wasn’t disgusted; he was leaning closer, his expression one of pure, unadulterated lust. A wave of relief and dark amusement washed over David, and he laughed, a low, breathy sound. The laugh made his cock pulse in Jenny’s hand.
Without her knowing, he gave Frank a subtle nod, a clear signal to join them. Frank didn’t hesitate. He slipped into the room silently, shedding his clothes in a pile on the floor before stepping down into the hot tub. The water sloshed as he moved in behind Jenny, wrapping his arms around her waist and pulling her back against his chest. He claimed her mouth in a passionate, demanding kiss, and she responded instantly, her hand never stopping its slow stroke on David.
David’s hands moved to cup Jenny’s face, tilting her head up to deepen their kiss as Frank’s hands began to roam. Jenny quivered, a soft gasp swallowed by David’s mouth as one of his hands slid down her stomach, over the sensitive nub of her clit, and then lower, his fingers dipping into her heat. Her skin was on fire, every nerve ending alight. Then a second set of lips kissed the nape of her neck, followed by a gentle nip on her earlobe, and two hands reached around from behind to massage her small, developing breasts.
The sensation of being touched, possessed, by both her brother and her cousin at once was overwhelming. She almost came on the spot. She turned her head to see who the second lover was. She had her suspicion, and when she saw her brother’s beautiful smile, their lips met, kissing passionately. His hands were on her breasts, pulling her back against him. She gasped, her body trembling as she pressed against his cock. They separated after a moment, enjoying their embrace.
She went to David, who had sat down in the water, his cock still hard and thick, jutting out from his body. Jenny impaled herself on his rigid cock, her body trembling. Frank impaled her from behind, his cock sliding into her ass. They slowly found a rhythm, their bodies moving in sync, their breaths mingling, their moans echoing off the walls. David sucked her small, perky breasts, his tongue lashing at the hard peaks, his teeth grazing the sensitive flesh. Frank ploughed her ass, deep and sensual, his body trembling as he pressed against her. He reached around, his fingers sliding over her clit, his thumb rubbing against the hard nub.
She came and came as these two older boys took her hard, her body trembling, her moans echoing off the walls. She arched her back into Frank’s as she felt them approaching their orgasms. She screamed she was safe to David, her voice raw and desperate. She told the boys to fill her, her voice filthy with need. And they blasted away into her—filling her pussy and her ass, their cocks throbbing, their bodies trembling.
She fell forward onto David, her body trembling. Frank’s hands still gently held her hips. He bent forward as she sat up, his lips on her neck, his tongue licking at her skin, his semi-hard cock still buried in her ass. She loved it, small tremors still traveling through her.
“Thank you, both of you — that was incredible!” she said, her voice raw.
The hot tub water churned around them, a frothy mix of steam and secrets, but the clock on the wall was a ticking time bomb. Jenny knew her parents could be home any minute. The thrill was intoxicating, but so was the fear.
"We can't stay here," she gasped, her voice tight with a desperation that was both for more and for safety. "Not enough time."
David and Frank shared a look, a silent, predatory understanding passing between them. They didn't need words. Frank was the first to move, lifting a dripping Jenny from the water. David grabbed a stack of fluffy towels from a nearby shelf, and they hurriedly wrapped her, their hands brushing, lingering for a second too long.
The dash through the cool night air to the back door was a blur of naked skin and hushed laughter, a frantic race against the inevitable sound of a car in the driveway. They burst into Frank’s room, slamming the door shut behind them. The space was small, smelling of teenage boy and laundry, but it was a sanctuary. There was no time for hesitation, no room for slow seduction. This was pure, frantic need.
Jenny dropped the damp towel to the floor and scrambled onto Frank’s unmade bed, the springs groaning under her weight. Instead of lying back, she went to her hands and knees, presenting herself to her brother in an unspoken invitation that was both innocent and utterly depraved.
Frank was on her in an instant, gripping her hips. He fumbled between them, the head of his cock nudging against her slick entrance before he pushed inside, a single, deep thrust that stole the air from her lungs and made her cry out. He filled her completely, a perfect, familiar fit from this new, deeper angle. But before she could lose herself in the sensation of her brother, David was there, kneeling on the bed in front of her. His cock, still glistening from the hot tub, was hard and proud, and he guided it to her lips.
She opened for him eagerly, a moan vibrating in her throat as Frank began to move. They found a brutal, desperate rhythm instantly. Frank filled her pussy, his hips slamming into hers with a force that made the bed frame smack against the wall, while David fucked her mouth, his hands tangled in her hair, setting a pace that matched his cousin’s. They were a single, writhing entity, their bodies moving in sync, their hips jerking in a primal dance. Their breaths mingled, ragged and hot, their moans echoing off the walls of the small room, a symphony of forbidden pleasure.
The pressure built inside Jenny, a coiling spring of pure sensation. Every thrust from Frank pushed her closer to the edge, every deep slide of David's cock in her mouth was a new kind of heaven. She was lost, a vessel for their shared lust, and she loved it. The first orgasm hit her like a tidal wave, her body trembling uncontrollably, her hips jerking back against Frank as she cried out around David's shaft. But they didn't stop. They hammered away at her, chasing their own release as she crested again and again, each wave more intense than the last.
She heard Frank groan, his rhythm faltering as he buried himself deep inside her, his cock throbbing as he came. A moment later, David tensed, his grip on her hair tightening as he filled her mouth with shot after shot, his body trembling with the force of his release. Jenny swallowed, her own body still convulsing with the aftershocks of her multiple orgasms.
They collapsed onto the bed in a tangled, sweaty heap, the only sound their mingled, panting breaths and the frantic beating of three hearts that had just risked everything. The air in the room was thick and humid, smelling of chlorine, sex, and their own exertion. For a moment, they just lay there, a jumble of limbs in the dim light, the frantic energy slowly ebbing away into a warm, sated glow. Frank’s hand rested possessively on the small of Jenny’s back, while David traced idle circles on her shoulder.
A car door slammed outside, the sound sharp and unnaturally loud in the quiet aftermath. Jenny’s head snapped up, her eyes wide with a sudden, piercing fear. "That's Dad," she whispered, the words barely audible.
Panic, cold and sharp, cut through the post-coital haze. In a single, fluid motion, she untangled herself from them, her movements suddenly clumsy with urgency. She snatched the damp towel from the floor, clutching it to her chest as she scrambled off the bed. "I have to go," she breathed, her gaze darting between the two of them—a silent, shared understanding of the narrow escape they'd just had.
Frank and David watched her, frozen, as she padded silently to the door. She gave them one last, fleeting look—a mixture of terror and a lingering, secret satisfaction—before slipping out into the hallway and disappearing toward her room. The sound of tires crunching on the gravel driveway grew louder, closer.
Frank let out a shaky breath he hadn't realized he was holding, running a hand through his sweat-damp hair. "Holy shit," he murmured, his voice low and awestruck. "That was too close."
David just nodded, his eyes fixed on the closed door, a slow, triumphant smile spreading across his face. They had been so lucky.
