Alyssa walks softly down the hallway, heading for her room after a long shower. As she passes her brother’s door, something catches her eye. Her brother's door is wide open, and Tyler is lying naked on his bed.

Her eyes got big and her mouth dropped open. His hand moves lazily up and down his cock, stroking himself with no hint of embarrassment. Alyssa freezes, eyes fixed on the surprisingly long, but not very thick cock standing between his legs.

He sees her. He definitely sees her. But Tyler doesn’t stop. If anything, his strokes grow slower, more deliberate.

Alyssa tells herself to keep walking, to go straight to her room. She should close the door, pretend she never saw this. But her feet stay planted on the carpet. Her heartbeat thumps in her ears as curiosity melts into raw, heavy arousal.

She stays, barely breathing, watching his hand glide over the length of his erection.

Minutes pass. Tyler’s breathing deepens, his body tensing. Alyssa swallows hard, eyes wide as his cock throbs violently in his fist. Then it happens — thick, white ropes shoot high into the air, one after another, landing across his stomach and chest. He groans softly, lost in his own release, and Alyssa counts them — not one or two, but ten, maybe twelve solid shots of cum before his orgasm tapers off into smaller shots that dribble down the head of his cock.

The silence is electric. Alyssa can still hear her own heartbeat.

“That…” She finally manages to speak, voice breathless. “That was a lot of cum.”

Tyler glances at her, almost amused. “It’s always like that,” he says casually, as though he hadn’t just coated himself with a load that could drown an amateur porn star.

Alyssa doesn’t answer. She forces herself to move, slipping into her room and closing the door fast. Her legs feel weak. Her nipples ache under her T-shirt, and between her thighs there’s a persistent tingle she can’t ignore.

She hadn’t planned on some alone time tonight — but after watching her brother jacking off, it’s not even a question. Alyssa peels off her shorts, dropping onto her bed with shaking fingers. The image of Tyler stroking his long, hard cock plays over and over in her head, every shot of cum burned into her memory.

By the time she finishes getting herself off a couple of times, she’s panting, sweaty, and still not satisfied.

The next day, she can’t focus on anything. Every thought leads back to Tyler — his cock, that huge, unending load that he shot. Alyssa bites her lip in class, mind wandering, imagining his cum shooting across her tongue or inside of her instead of spilling over his stomach.

She tries to remind herself of her rule — she’s holding onto her virginity as long as she can. But that doesn’t mean she’s innocent. Alyssa loves giving head, loves making guys cum in her mouth. She swallows and loves the taste. And unlike most people, she was born without a gag reflex — a fact that has made a lot of boys very, very happy.

Still, Tyler feels different. It’s not just the size or how much he shoots. It’s that they are family! Tyler is her younger brother. But the way he looked right at her and didn’t stop. Like he didn’t care if she was watching.

That afternoon, after gymnastics, as Alyssa walks past his door again, she feels her stomach clench. And there he is — lying on his bed once more, hand working up and down his cock.

She stops in the doorway, heart hammering. Her brother doesn’t say a word. He doesn’t even look up this time. But his breathing quickens as his fist slides over his long, hard cock.

Alyssa’s mouth goes dry. She knows she should leave, but she can’t. She’s transfixed as his tummy tightens, his body bows off the bed, and another massive load erupts from the tip of his cock. Long, sticky ropes splash across his chest, ribs, and the sheets, the head of his dick still spewing out smaller shots as he groans through the aftershocks.

Again, silence stretches between them, charged and intimate.

“I still can’t believe how much you cum,” Alyssa whispers, almost to herself.

Tyler finally looks at her and smirks faintly. “You gonna stand there every time I do this?”

Alyssa’s cheeks burn. She spins on her heels and heads for her room, slamming the door behind her. But this time she doesn’t even bother pretending. She throws herself on the bed, yanking off her clothes, fingers diving between her thighs as images of Tyler’s orgasm replay in perfect, filthy detail. 

She pushed herself through as many orgasms as she could possibly muster up. And this time, it’s not enough. Alyssa wants more. Much more.

The next day, Alyssa makes up her mind. Watching her brother wasn't enough, she needed to feel him, taste him, find out what that enormous load is like when it’s not spilling uselessly onto his stomach.

She times it perfectly. Tyler’s at riding class until three, and she’ll be waiting when he comes back.

Alyssa stands near his bedroom door in just a thin T-shirt and soft cotton shorts, her long blonde hair braided into a sleek ponytail. Her heart is racing, but her dark green eyes gleam with determination. She feels her nipples are so hard they hurt, small points that could cut glass. Her body’s humming with anticipation, lean legs shifting restlessly as she waits.

When Tyler finally opens his door, he stops cold. “Uh what are you doing by my room?”

“Take off your shirt,” she says. Her voice is steady, even though her pulse is thundering.

Tyler blinks. “What?”

“Just do it.” Alyssa steps closer, close enough for him to see the spark in her eyes, the nervous smile tugging at her lips.

He hesitates only a moment before tugging his T-shirt off. Alyssa kneels in front of him, back straight, resting her tiny ass on her heels. With a smooth motion, she hooks her fingers into the waistband of his shorts and underwear, sliding them down to his ankles.

Tyler’s cock hangs soft, not showing its true length. He is definitely a grower. Alyssa grips it lightly in her right hand, holding it up toward her mouth as she leans forward.

“Oh, Jesus,” Tyler breathes as her lips close around him.

Her mouth is warm and soft, sliding easily over his shaft as it swells rapidly, lengthening, stiffening. Alyssa hums around him, savoring the way he responds — the sharp inhale, the slight tremor in his thighs. His cock is long, straight as an arrow, crowned with a clean, perfect head. Not overly thick, but impressive enough that it makes her want more than just feel it against her tongue.

Tyler’s mind spins. This is really happening. My sister is sucking my cock. He’d never imagined her in this position,  but today it was happening.

Alyssa works him in long, deep strokes, taking him all the way to the back of her throat without so much as a gag. When she pulls back, only the tip rests between her lips — then she plunges down again, swallowing him whole.

“Holy,” Tyler groans, his hands twitching at his sides. He doesn’t know where to put them — on her head? In her hair? He’s too overwhelmed to decide.

Alyssa doesn’t need guidance. She works on him with practiced skill, her tongue swirling around the head, her lips tightening just enough to make him gasp. She loves how quickly he responds — how his shaft grows rock hard, how his breathing gets ragged as she sucks him deeper and deeper.

Ten minutes pass in a haze of sloppy cocksucking sounds. Alyssa feels him tense, his head swelling in her mouth, his shaft going rigid as a steel rod. His toes curl against the carpet.

He’s ready!

Alyssa pulls back slightly, leaving just the last few inches in her mouth. She focuses on the tip, working her lips and tongue with quick, hungry precision.

“Um… Alyssa… I’m gonna—”

His words cut off in a strangled groan as he erupts. Huge, thick ropes of cum spill into her mouth, shot after shot. Alyssa keeps her lips sealed tight around his dick, feeling every surge as his cock jerks against her tongue. His load is massive — far more than any guy that she's blown before — but she takes it all easily, savoring the moment, the taste, the sheer volume.

When the last shots fade, Tyler’s cock is painfully sensitive. Alyssa is gentle, milking him with soft lips and a steady hand until every drop is coaxed out. Then, with a wet pop, she lets the head slip free.

She tips her head back, showing him his load that had filled her mouth.

Tyler stares down in disbelief. His legs feel weak. Did that really just happen?

Alyssa swallows deliberately, smiling as his seed slides down her throat. “Mmm,” she purrs. “Delicious.”

As she stands, Tyler blurts out, “Why… why did you just do that?”

Alyssa meets his gaze without flinching. “Ever since I watched you the other day, I couldn’t stop thinking about it. About this.”

He’s stunned silent for a moment. Alyssa tilts her head playfully. “You mad at me?”

“No,” Tyler says quickly. “Just… No one's done that to me before. I wasn’t expecting this, let alone having my sister do it! Do you really like… doing that?”

In answer, Alyssa slides a finger between her thighs, over her still-pure slit. She lifts it, glistening, showing him the clear, sticky fluid,  proof of her arousal. “Does that answer your question?”

Tyler swallows hard, unable to speak.

“Want a taste?” Alyssa asks, holding her finger out.

Tyler froze, eyes wide, unsure whether to lick, laugh, or run. Alyssa shrugs, slipping her finger into her mouth and licking it clean, a teasing smile tugging at her lips. “Your loss,” she murmurs.

Standing up: “I’m going to my room now,” she says, sliding past him. “If you want to watch, come over. Or if you want another blowjob… just let me know.”

Before he can reply, she’s gone. The door clicks softly behind her, leaving Tyler standing in stunned silence. Half-hard, frozen, and completely flustered, he goes into his room. His chest hammers, and every nerve in his body is screaming.

For a long minute, he stares at the closed door, mind racing with images of her teasing smile, the slick finger, the curve of her tiny little ass. He shouldn’t be thinking this way — she’s his sister — but his body doesn’t care.

By the time he finally moves, his decision is made. Alyssa left the invitation, and he can’t ignore it. He pulls on a T-shirt, grabs his laptop off the floor, and creeps quietly down the hall. Her door is slightly ajar, a warm light spilling into the dim hallway.

He hesitates just outside for a second, listening. He hears soft breaths, the faint rustle of sheets, the quiet hum of anticipation. With a deep exhale, he pushes the door open and slips inside.

Alyssa is lying on her bed, back arched, fingers moving lazily between her thighs. She looks up and smiles, a little mischievous, a little shy. “Took you long enough,” she murmurs.

“I… I didn't know what to do, I still don't,” Tyler admits, voice quiet, nervous with desire. His pulse thunders in his ears.

She pats the mattress, inviting him closer. “Then come. Watch me… or help. Your choice.”

Tyler kneels beside her, careful not to rush, not sure what to do. She spreads her legs further, giving him easy access, and lets her fingers slide against her tiny slit. The smell of lust in the room is thick, heavy, and Tyler feels it pull him like gravity.

Alyssa’s moans are soft as she rocks her hips over her hand. Her small nipples are taut, dark against her pale skin, and she tells Tyler to lean in closer. He hesitates and does as she says. "Want a lick? Lean down and give it a try," she invited him. Leaning in, he lets his tongue brush the delicate skin between her thighs.

“Oh… yes,” Alyssa breathes. She guides him gently, showing him exactly where she wants him, how she wants him to touch her. Tyler’s nervousness melts into a slow, steady rhythm as she teaches him. Her small hands hold his head, directing him, coaxing out sounds he didn’t know she could make.

Tyler’s confidence grows. He laps, circles, teases, as Alyssa arches into him, whispering encouragement. Every soft moan, every tiny shiver, feeds his desire, makes him harder. He’s lost in her completely — her scent, her taste, the desperate need in her dark green eyes.

When she lifts her hips higher, grinding softly against his face, Tyler groans and continues licking her pussy, tasting her, exploring her little slit. Alyssa’s fingers tighten in his hair, holding him tight as wave after wave of pleasure builds. Her hips rock faster, more insistently, and she can’t stop the gasping, whimpering moans spilling from her mouth.

“Tyler… right there,” she whispers, her voice strained. “Don’t stop… don’t stop…”

Her first orgasm hits with a shiver and a quiet, broken cry. Tyler keeps working her, refusing to let the moment end, and she rides out the waves, panting and trembling. When she’s finally spent, she collapses back against the pillows, chest heaving, every nerve still alive.

Tyler sits back for a moment, catching his breath, eyes wide and face glazed. “I… wow,” he murmurs.

“You liked that, didn’t you?” Alyssa teases, still glowing, still flushed. “It’s not just about me. You like this just as much as I do.”

Tyler swallows, unable to form words. The truth hits him — he’s addicted already, desperate for more, and he knows she is too. Her needs, her teasing, the way she takes control — it’s intoxicating.

Alyssa slides a hand down between them, brushing against him now. “Now,” she says softly, “I want you inside me. I want you to take my virginity from me.”

And Tyler, quiet, shy, and still in awe of her, nods. He moves closer, and they are ready to cross a line in the most taboo way, knowing this is just the beginning.

Alyssa lies back, head on a pillow, chest heaving, eyes dark with want. Her small hands glide over her little, wet slit, teasing herself even after her first orgasm. She catches Tyler staring, every muscle in his body tense.

“Come closer,” she whispers, soft and sultry. “I want you to be my first.”

Tyler hesitates only a second, then kneels beside her. His hands shake slightly as he slides over her legs, cupping her thighs, feeling the electricity radiating from her body. He’s never been this close to a girl before — intimate, raw, and completely open to him.

“Should we be doing this? Isn't this wrong in so many ways?” he asks, eyes flicking to hers.

“It is completely wrong,” Alyssa murmurs, “but I want you to be my first. Unless you don't want to.'

Tyler swallows hard and nods. She spreads her legs, tilting her hips upward. He leans in, brushing his lips over her small mound, tasting her, exploring with careful but eager movements. Alyssa’s moans are soft at first, building as he learns how to please her, how to stroke his tongue over the spots that make her shiver.

She guides him, hands on his head, showing him exactly what she likes, when to press, when to circle. Every soft moan, every tremor of her body, drives him harder. He can feel himself getting harder by the second, desperate to touch her even more intimately.

“Tyler… don’t stop,” she gasps. “Right there… yes, just like that…”

Her hips grind gently against his face, and he laps and circles, taking in everything his sister wants to offer him. She’s warm, wet, and responsive, and the sounds she makes ignite a fire inside him.

Alyssa’s hands slide down his back, tugging him closer as her moans grow louder. She lifts her hips higher, riding his tongue, building tension, until her second orgasm hits. She arches her back, trembling, crying out softly, and Tyler keeps going, unable to resist, feeling the thrill of controlling her pleasure.

When the waves fade, Alyssa rolls onto her side, looking at him with a playful, wicked grin. “Your turn,” she says, nudging him closer.

Tyler swallows, heart hammering, and positions himself. Alyssa spreads her legs, lifts her hips slightly, and he slowly slides into her bare pussy. The sensation is overwhelming — tight, warm, and impossibly inviting. Alyssa gasps, gripping his shoulders.

“Slow,” she whispers. “Fuck me slowly.”

Tyler nods, moving gently at first, feeling her stretch and accommodate him. Each shallow push is electric, every tiny shiver and whimper from her urging him deeper. Her hands clutch his back, guiding him, drawing out the connection.

“I can’t… I don’t know if I’ll last,” Tyler murmurs, voice breathless. “It feels too good.”

“You don’t have to,” Alyssa says, quiet but firm, as he adjusts inside her. “Just do what you can.”

The room is filled with soft gasps, whispered encouragement, and the rhythmic sound of their bodies moving together, Tyler finding a steady pace, building intensity without rushing. Alyssa matches him, rocking her hips, wrapping her legs around him, urging him to push harder, faster.

“Harder,” she whispers, voice low and urgent. “Fuck me, Tyler. Don’t stop… don’t stop!”

Tyler obeys, thrusting deeper, his own moans mingling with hers. She’s perfect around him — tight, warm, responsive, every curve pressing against him like it was made for him. His body aches to feel her, to keep going, to reach the point where neither of them can hold back.

Alyssa bites her lip, nails digging lightly into his shoulders as her body tenses. “I’m… so close…” she gasps. Tyler feels her clench around him, her tight pussy gripping, driving him to the edge.

With a deep groan, Tyler pushes fully inside, the head of his cock touching her cervix, and unloads several ropes of cum into her. Alyssa cries out softly, hips bucking against him as she rides out the intensity. Her eyes roll back, fingers clutching his arms, body trembling.

They collapse together, breathless, hearts hammering. But even as their first orgasm fades, the craving doesn’t. Tyler’s still hard, Alyssa’s still shivering with need....
