Sister is a slut pt 1

The following story is fictional and does not depict any actual person or event

The hallway light bled under Billy's door, casting a sharp line across his tangled sheets. He blinked awake, disoriented, until the digital clock's red glow snapped him back—3:07 AM. The shower hissed down the hall, its rhythmic patter louder than usual. His throat tightened. No one showered at this hour.

The bathroom door clicked open. Footsteps padded toward his room, deliberate and slow. His pulse hammered as the knob turned. His seventeen year old sister Jane stood silhouetted in the doorway, steam curling off her bare skin. She didn't speak, just let the towel drop with a wet slap. Moonlight traced the curve of her hip, the dip of her waist.

Water beaded on her collarbones, sliding down between her breasts. Her nipples stood taut from the cold—or something else. The fifteen year old's mouth went dry watching a droplet roll over the swell of her stomach, vanishing into the dark patch of hair between her thighs. She smelled like shampoo and sweat, something heated underneath.

Jane stepped closer, letting him see the way her inner thighs glistened, still damp from the shower. Or maybe not just the shower. His dick twitched under the sheets as she climbed onto the mattress, her knees sinking into the worn fabric beside his hips. The heat of her radiated against him, her breath hitching when their skin touched.

Her hand slid down her own stomach, fingers brushing through the wet curls between her legs. "Feel how warm I am," she murmured, guiding his trembling fingers there. The moment they touched her, she gasped—her pussy was slick, swollen, already parted. A shudder ran through her as she pressed his fingers deeper, letting him feel the tight, clenching heat inside.

Billy's breath came ragged as she rocked against his hand, her hips moving in slow, needy circles. Her breasts swayed with each motion, the pink tips dragging across his chest. She tilted her head back, exposing the fluttering pulse in her throat. "You're gonna fuck me tonight, little brother." she whispered, raw and hungry. Not a question.

Her skin was fever-hot under his palms as he traced the dip of her spine, the swell of her ass. She arched into him, pressing her dripping cunt against his thigh, leaving streaks of slick arousal on his skin. The smell of her—musk and salt and something sweet—filled the space between them. He could see every detail in the dim light: the way her inner thighs trembled, how her clit stood swollen and begging.

Jane’s nipples hardened further as his mouth found one, his tongue circling the stiff peak until she moaned. She grabbed his hair, forcing him to look up at her—her lips parted, her pupils blown wide. “Touch me again,” she demanded, guiding his hand back between her legs. His fingers slipped easily into her wetness, her hips jerking as he curled them inside, finding that spot that made her whimper.

She rocked against his touch, her thighs squeezing around his wrist as she chased her pleasure. The scent of her arousal thickened, mingling with the humid heat of the room. Her breath hitched when he rubbed tight circles over her clit, her back arching off the bed. “Fuck—” she gasped, her nails digging into his shoulders. “Billy, I need your cock inside me. Now. Fuck me Billy” Jane whispered as she bounced on him, "now I wanna be your slut" He watched her titties rise and fall in rhythm and pushed his hips forward.

Jane reached down, wrapping her fingers around his shaft. His hips jerked at the contact, his breath coming in ragged bursts. She stroked him slowly, her thumb smearing the precum beading at his tip. The way she looked at him—dark-eyed and hungry—sent a shiver down his spine. “You’re so hard for me,” she murmured, her thumb pressing against the sensitive ridge beneath his head. “You wanna feel how tight I am?”

Her breasts swayed as she grinded against him, her nipples grazing his chest before she positioned herself above his 8 inch cock. The damp heat of her cunt hovered just above him, teasing. He could see every detail—the swollen pink folds, the way they glistened, slick and parted, begging for him. She let out a soft moan as she lowered herself, her body stretching to take him inch by inch, her thighs trembling with the effort.

Billy gasped as her tight walls clenched around him, hot and pulsing. She arched her back, her full breasts bouncing slightly with each shallow thrust as she adjusted to his length. His hands gripped her hips, feeling the flex of muscle beneath her smooth skin as she began to move. Her inner thighs were damp with sweat and her own arousal, the scent of sex thick between them.

Jane leaned closer, her breath hot against his ear. "Remember last summer?" she whispered, her voice raw. "When you lost your virginity to me?" Her hips rolled in a slow circle, dragging a groan from his throat. His fingers dug into her flesh—he remembered. The sticky August heat, her hand guiding his between her thighs in the barn while dad was in the pasture and Mom was inside making lemonade.

"You came so fast," she taunted, nails scraping down his chest. "But now you last long enough to make me feel good."

Billy remembered that afternoon too vividly—the hay scratching his bare knees, Jane's fingers wrapped around his wrist as she shoved his hand under her cutoff shorts. How he'd barely lasted fifteen seconds inside her before spilling like a dumb kid. Heat crawled up his neck even now, his cock twitching inside her as she smirked.

Jane's hips rolled harder now, her wetness dripping down his shaft as she rode him with slow, deliberate strokes. She tilted her pelvis just right, grinding her clit against him with each downward thrust until her thighs shook. "Mm, you're getting better," she breathed, raking her nails down his stomach. "But I still haven't come yet."

Billy gripped her hips tighter, thrusting up into her heat as she moaned. He knew her tells—the way her breath hitched right before she clenched around him, the flush creeping down her chest. She'd taught him all of them, ever since that first fumbling summer.

Jane's thighs trembled as she rode him faster, her slick folds dragging along his length with every bounce. She bit her lip, eyes half-lidded as she watched him—hungry, possessive. "Remember when Mom almost caught us?" She gasped, grinding down hard just to feel him twitch inside her. "You froze up so bad I had to finish myself off after."

Billy groaned, fingers digging into the soft flesh of her ass. He remembered. The basement couch, her skirt hiked up around her waist, her hand clamped over his mouth to keep him quiet. The way she'd shoved him off the second the floorboards creaked upstairs, leaving him throbbing and desperate while she smoothed her clothes like nothing happened.

Jane laughed now, breathless, riding him harder as she watched his face. "You were so scared," she teased, pinching his nipple until he hissed. "But you still got hard again the second she left." Her hips rolled in a slow circle, dragging his cock against that spot inside her that made her thighs clench. "Just like now."

Billy remembered the damp ache in his jeans afterward, how he'd jerked off imagining her fingers while she smirked at him across the dinner table. He'd been rock-hard through Dad's grace, through Mom's meatloaf, through Jane kicking his shin under the table every time he looked at her too long.

Her teeth scraped his shoulder now, sharp enough to sting. "Pay attention," she growled, riding him harder, her wetness smearing across his thighs. The bedframe creaked—too loud—but neither of them slowed. Jane never slowed. She'd dragged him into laundry room, empty pastures, the treefort they played in as kids, even the backseat of Dad's truck when it was still warm from his drive home. Always leaving him dazed, desperate, marked with bites and scratches that took days to fade.

Billy knew the exact moment she was close—her breathing hitched, her thighs tightened around him, her cunt fluttered like a fist around his cock. She grabbed his hair, yanking his head back to watch her tits bounce as she fucked herself on him. "Make me come," she demanded, her voice cracking. Not a request. Never a request.

He thrust up harder, angling his hips just how she'd taught him last time—that deep, grinding stroke that made her nails dig bloody crescents into his shoulders. Her moan was loud, unrestrained, her wetness dripping down his balls as her back arched. "Fuck, yes—right there—"

Her pussy clenched around him in rhythmic pulses, milking his cock as she came with a shuddering gasp. The sight of her—head thrown back, tits bouncing, thighs quivering—sent heat coiling tight in his gut. But Jane wasn't done. She leaned down, her sweat-slick chest pressing against his, and licked a stripe up his throat. "You don’t get to come yet," she breathed, rolling her hips in slow, torturous circles.

Billy groaned, his fingers digging bruises into her hips as she teased him, lifting herself almost entirely off his cock before sinking back down with a wet slap. She laughed at his desperation, grinding her clit against his pelvis until her breath hitched again. "Feel how tight I get when I'm about to come?" she whispered, guiding his hand between their bodies to rub rough circles over her swollen bud.

Her thighs trembled as she fucked herself on him, her moans turning breathy and high-pitched. Billy could feel her walls fluttering, her slick coating his shaft as she rode him faster, chasing another orgasm. "God, you're so deep," she gasped, her nails raking down his chest. The sting only made him thrust harder, their skin slapping together in the humid dark.

Jane's breath hitched when his thumb pressed harder against her clit, circling just the way she liked. "Fuck—right there—" Her hips jerked, her cunt clamping down around him like a vice as she came again, her back arching off the bed. She didn't let him pull out—just ground herself against his cock, milking every last pulse of pleasure until her legs shook.

Billy could feel his own climax building, his balls tightening as she rode him through her aftershocks. Jane smirked when she noticed, rolling her hips in slow, deliberate strokes that had him gasping. "Not yet," she murmured, squeezing him inside her until he groaned. She leaned down, her nipples brushing his chest as she whispered, "I want you to remember this next time you jerk off alone."

Her fingers tangled in his hair, forcing his head back against the pillow as she increased her pace. The wet slap of skin filled the room, her swollen cunt gripping him tighter with every downward thrust. Billy could see the flush spreading across her chest, the way her lips parted around ragged breaths as she fucked him toward the edge.

Jane’s thighs quivered when she felt him pulse inside her, her walls fluttering in response. "Almost," she taunted, slowing to a torturous grind that had him bucking beneath her. His hips jerked uncontrollably—she’d taught him too well, knew exactly how to drag it out until he was gasping.

He shifted his weight to plunge deeper into her, he was about to cum and she felt it. Jane clenched around him suddenly, her inner muscles rippling in deliberate pulses as she milked him. "Come inside me, fill me up, I don’t care if you get me pregnant," she breathed against his lips—not a request but a command, her hips rolling in slow, possessive circles. Hot streaks of pleasure coiled tight in his gut before erupting; his vision whited out as he came inside her with a choked groan.

Jane whimpered as she felt his cock twitch inside her, his cum flooding her in thick pulses. She kept riding him through it, grinding her swollen clit against him until her thighs shook and another broken moan tore from her throat. Wetness seeped between them—his cum, her arousal—dripping down his shaft as she finally stilled, panting against his shoulder.

Billy’s hands slid up her sweat-slick back, fingers tangling in her damp hair as she slumped against him. Her heartbeat hammered against his chest, her breath hot and uneven on his skin. She didn’t pull away—just pressed closer, letting him feel the way her cunt still clenched around him in lazy aftershocks.

His cock twitched inside her, still hard despite his release. Jane chuckled against his collarbone, nails scraping lightly down his ribs. "Still hard," she murmured, rolling her hips just enough to make him groan. Her thighs tensed, squeezing around him as she rocked in a slow, filthy grind, milking every last drop.

The scent of sex hung thick between them—musky, primal. Jane lifted herself slightly, watching his cum leak from her swollen folds before pressing back down with a wet sigh. "Messy," she taunted, dragging a fingertip through the mess on her inner thigh and licking it clean with a hum. Billy's hips jerked involuntarily, his cock throbbing inside her.

A floorboard creaked down the hall. Both froze—Mom's insomnia meant midnight bathroom trips. Jane clapped a hand over Billy's mouth, her cunt tightening around him in a way that made his eyes roll back. "Shhh," she breathed, her other hand pinching his nipple hard as footsteps padded past his door. The thrill of almost getting caught sent fresh heat pulsing through his veins.

Billy bit back a groan as Jane began moving again, slow and slick, his cum easing her strokes. She smirked at the way his hips bucked upward—no control left, just raw need. Her fingers twisted in his hair, yanking his head back to expose his throat. "You'd fuck me right now even if she walked in, wouldn't you?" she whispered, scraping her teeth along his jaw.

Down the hall, the toilet flushed. Jane rolled her hips harder, her swollen folds dragging along his oversensitive cock, milking another thick pulse from him. The bathroom door squeaked open. Jane didn’t stop—just locked eyes with him and ground down, her cunt fluttering around him as footsteps paused outside his door.

Billy’s breath hitched when the doorknob rattled. Jane clamped a hand over his mouth again, her nails biting into his cheek as she whispered, "Stay quiet or I’ll stop." The threat was hollow—her hips kept moving in slow, filthy circles, her thighs trembling when she felt his cock twitch inside her. The footsteps retreated toward the master bedroom.

Jane waited until the distant click of Mom’s door before peeling her hand away. "Scared you’d get caught?" she taunted, rolling her hips with deliberate slowness. Billy groaned—she was grinding his cum deeper into her, her swollen cunt gripping him tight even as their mess dripped onto the sheets. The scent of sex was overwhelming now, thick and humid between them.

She leaned down, her sweat-slick chest pressing against his, and licked his earlobe. "You loved it," she breathed, biting hard enough to leave a mark. Her thighs squeezed around him as she dragged his hands to her breasts, forcing him to knead the soft flesh until her nipples stiffened again. The bed creaked under their shifting weight—too loud, always too loud—but neither of them cared.

Billy could feel her getting wetter around his softening cock, her cunt pulsing with shallow clenches as she teased herself on him. Jane moaned low in her throat, her fingers twisting in his hair as she arched her back, rubbing her clit against his pelvis in slow, filthy circles. "Gonna make you hard again," she whispered, her breath hitching when his thumb found her nipple. "Gonna ride you till you can't walk tomorrow."

The sheets clung to their sweat-slick bodies as she rolled her hips faster, the wet squelch of their combined fluids loud in the quiet room. Billy groaned when she lifted herself almost off him completely, then sank back down with a shudder, her inner walls fluttering around his sensitive cock. She laughed breathlessly at his twitch beneath her, grinding harder when she felt him start to stiffen again inside her.

Jane’s fingers dug into his chest as she rode him with renewed hunger, her damp hair sticking to her flushed skin. “Feel that?” she panted, dragging his hand between her legs where their bodies joined. “Still so wet for you.” His fingertips brushed her swollen clit, and she jerked forward with a gasp, her thighs clamping around his hips as another ripple of pleasure tore through her.

Billy could feel his cock hardening again inside her, her tight heat coaxing him back to full thickness as she rolled her hips in slow, filthy circles. She moaned when he gripped her ass, nails biting into the soft flesh as he thrust upward—deep enough to make her breath catch. “Yeah, just like that,” she murmured, her voice rough as she leaned down to capture his mouth in a kiss that was all teeth and tongue.

Jane’s body arched when his thumb found her clit again, her thighs trembling as he rubbed tight, relentless circles over the swollen bud. She broke their kiss with a gasp, her nails raking down his chest as she rode him harder, chasing another climax. The wet slap of their bodies filled the room, mingling with her ragged moans and the creak of the bedsprings under their frantic movements, as she moaned, “Yes, make me cum”

Billy groaned when her cunt clenched around him suddenly, her inner muscles rippling in rhythmic pulses as she came with a shuddering cry. She bit down on his shoulder to muffle the sound, her hips jerking erratically as pleasure ripped through her. Hot liquid dripped down his shaft—her cum, his, both—making every thrust slicker, filthier.

Jane collapsed against his chest, her breath ragged, but she didn’t stop moving. Her thighs trembled as she ground against him, milking his cock through her aftershocks. “Again,” she demanded, voice raw, and Billy knew she wouldn’t let him rest until she’d wrung every last drop from him. Her fingers dug into his hips, guiding his thrusts deeper, faster.

His cock throbbed inside her, the overstimulation blurring into pleasure as she clenched around him with each downward stroke. Jane’s moans turned breathy, high-pitched—the sound she made when she was close but refusing to let herself come just yet. “Faster,” she gasped, raking her nails down his stomach until he obeyed, his hips slamming up into his sisters slick heat.

The headboard knocked against the wall in a steady rhythm. Billy’s vision swam as she rode him harder, her swollen clit rubbing against his pelvis with every bounce. She was close—he could feel it in the way her thighs shook, how her cunt fluttered around him like a fist.

Jane’s breath hitched right before she came, her entire body seizing as she buried his cock deep inside her. Her nails drew blood down his chest, her moan muffled against his collarbone as her orgasm ripped through her. Wetness gushed around his shaft, dripping onto his balls as she trembled.

Billy could feel his own climax building again, his hips jerking uncontrollably beneath her. She clenched around him deliberately, milking him—her lips curled in a smirk when she felt his cock twitch inside her. "Come in me again," she panted, rolling her hips in slow, filthy circles. "Fill me up like last time." and he shot a load into his sisters pussy, “Fuck yes! Cum with me Billy!” she sighed as she shuddered to another orgasm.

Jane collapsed forward, her sweat-slick body pressed flush against his as their chests heaved in unison. She nuzzled into the crook of his neck, licking salt from his skin before biting down—hard enough to leave a bruise he’d have to hide tomorrow. Their combined fluids leaked between them, sticky and warm, as she shifted just enough to keep him trapped inside her.

Billy’s softening cock twitched when she clenched around him, her aftershocks milking him dry. “Still sensitive?” she teased, grinding down with deliberate slowness. He groaned, hips jerking involuntarily as she laughed—low and throaty—her breath hot against his ear. The scent of sex clung to them, muskier now, ripe with exertion and sweat.

Jane rolled onto her back, pulling him atop her with greedy hands. His spent cock slid from her with a wet sound, making her shudder. “Clean me up,” she ordered, spreading her thighs wider—her swollen cunt glistened in the dim light, his cum pooled between her folds. Billy’s tongue traced her inner thigh first, tasting salt and their mingled arousal before lapping upward in slow, deliberate strokes.

Her hips jerked when his tongue flicked over her oversensitive clit, a broken whimper escaping her lips. “Not—ah—not gentle,” she gasped, twisting her fingers in his hair to guide him harder against her. Billy obeyed, sucking her engorged bud between his lips until her thighs clamped around his ears, her moans pitching higher with each rough circle of his tongue.

Jane arched off the bed when he pushed two fingers back inside her still-throbbing cunt, her back bowing as his knuckles pressed against that spot that made her see stars. “Fuck, yes—right there!” Her heels dug into his shoulders, her wetness smearing across his cheeks as she fucked herself on his hand, her orgasm ripping through her with a choked cry.

Billy lapped at her frantically, drinking down every pulse of her arousal as she shuddered above him. The taste of salt and sex flooded his mouth—her cum, his, both—thick and primal. Jane collapsed back onto the sheets, her chest heaving, but her fingers tightened in his hair before he could pull away. “Again, little brother,” she gasped, thighs trembling as she dragged his mouth back to her swollen folds.

His tongue probed deeper this time, curling inside her as she arched off the bed with a guttural moan. Jane’s hips rolled in desperate circles, grinding against his face until her thighs locked around his head, cutting off his air. He didn’t stop—couldn’t—not when her cunt clenched around his fingers like a vise, hot and pulsing.

The scent of her was overwhelming—musky sweat, the tang of their combined cum, the earthy sweetness of her arousal soaking his tongue. She tasted like warm honey and salt, slick and thick on his lips. Billy buried his nose against her swollen folds, inhaling deeply as her orgasm crested again, her thighs shaking against his temples.

Jane yanked his hair hard enough to sting, forcing his tongue deeper inside her twitching cunt. “Lick me—fuck—yes—” Her moans hitched higher as his nose bumped her clit, the rough friction sending another shockwave through her. He could feel her pulsing around his fingers, her juices dripping down his wrist in hot streaks.

The scent was animal—ripe with exertion and musk, layered thick with the tang of their earlier couplings. Her arousal clung to his skin, sharp and sweet like overripe peaches left in the sun, mingling with the muskier undertones of his own release still leaking from her. Billy inhaled greedily, his cock twitching back to life against the sheets.

Jane laughed breathlessly above him, her thighs tightening around his head as she rocked against his mouth. "Like how I smell?" she taunted, grinding her swollen folds against his nose. The scent intensified—warm and wet, thick with salt and the earthy rawness of sex—making his tongue work harder between her slick lips.

Billy groaned against her, his nostrils flaring as he inhaled deeper, drunk on the musk of her arousal. Each breath pulled in more—the tang of their mingled cum leaking from her, the honeyed sharpness of her sweat-slick skin, the dark, primal musk that clung to the damp curls pressed against his chin. It was intoxicating, overwhelming, flooding his senses until his cock throbbed against the mattress.

Jane arched her hips higher, grinding herself against his face with a filthy moan. “Fuck, yes—more,” she gasped, her thighs trembling against his ears. The scent intensified as his tongue plunged deeper—ripe peach flesh gone over-sweet, the salt crust of dried sweat between her thighs, the humid musk of sex clinging to every fold. Her taste bloomed thick on his tongue, bitter-sharp and intoxicating.

Billy’s fingers curled inside her, pressing against that spot that made her spine bow off the bed. “There!” she cried, nails raking his scalp as her cunt pulsed around his knuckles. Wet heat gushed over his chin, her thighs clamping tight around his head as she came with a choked scream—her third, fourth? He’d lost count in the slick, panting dark.

Jane collapsed backward, her chest heaving as she dragged him up by his hair, smearing her juices across his mouth in a messy kiss. “Still hard,” she murmured against his lips, her hand sliding between them to wrap around his throbbing cock. “horny little brother.” Her grip tightened, stroking him with slow, filthy pulls that matched the roll of her hips against his thigh.

Billy groaned, his hips jerking into her fist as she squeezed the swollen head, thumb rubbing circles over the slit where pre-cum beaded. “Tell me you want to come again,” she breathed, biting his lower lip hard enough to sting. Her thighs squeezed around his leg, grinding her dripping cunt against his muscles as she jerked him faster, her nails digging into his shaft with every upward stroke.

The scent of her arousal clung to his skin—salty, musky—filling his nostrils each time she pulled him closer for another kiss. Jane’s tongue pushed past his teeth, tasting herself on him as she pumped his cock in rough, uneven strokes. “Gonna make you beg this time,” she whispered, tightening her grip until he gasped—her thumb pressing hard under the crown just the way he hated (and loved).

Billy shuddered when she suddenly released him, his hips jerking forward into empty air before she pinned his wrists above his head. Her thighs straddled his waist, her swollen cunt hovering just above his throbbing erection—close enough that he could feel her heat but not enough to sink into. “Please,” he groaned, bucking upward, but Jane just laughed, grinding her wet folds along his length without letting him inside.

Her fingers dug into his wrists as she leaned down, her nipples brushing his chest while her breath ghosted over his parted lips. “Say it,” she demanded, her hips rolling in slow, torturous circles that smeared her arousal along his shaft. Billy’s throat worked—he could feel her dripping onto him, could see the glisten of their mixed fluids coating his cock in the dim light.

Jane smirked when his hips jerked helplessly beneath her, her cunt hovering just above his tip. “Tell me you need my pussy,” she whispered, dragging her swollen folds along his length with a shudder. The wet heat of her was maddening—so close but not enough, not until she wanted it. Billy’s groan turned into a gasp when she suddenly sank down, taking him deep in one slick thrust that punched the air from his lungs.

Her walls clenched around him instantly, milking his cock with practiced pulses as she rolled her hips in slow, filthy circles. “Feel that?” she breathed, nails digging into his chest. “I'm still tight for you.” Billy’s vision blurred when she clenched tighter, her cunt fluttering around him in rhythmic contractions that dragged another thick drop of pre-cum from his swollen tip.

Jane arched her back, her sweat-slick breasts brushing his chin as she rode him with deliberate slowness. “Gonna make you last this time,” she taunted, lifting herself almost completely off before sinking back down with a wet gasp. The squelch of their combined fluids filled the room, mingling with the creak of the bedsprings as she ground against him, rubbing her swollen clit against his pelvis with each downward stroke.

Billy’s fingers dug into her hips hard enough to leave bruises, his cock twitching inside her oversensitive cunt. She laughed breathlessly when he tried to thrust deeper—her thighs clamped around him, controlling his movements with ruthless precision. “No,” she panted, rolling her hips in tight circles instead, her inner muscles rippling around him in slow, torturous pulses. “You don’t get to come until I say.”

Jane lifted herself up until just the tip remained inside, her slick folds stretched tight around him. "Beg," she ordered, her breath ragged—her own thighs shaking with the effort of restraint. Billy's hips jerked upward instinctively, but she pinned him harder, her nails biting into his hips as she hovered just out of reach. "Say you need my cunt," she whispered, grinding down in a slow, filthy circle that made his toes curl.

Billy gasped her name, his cock throbbing beneath her as she teased him with shallow, maddening strokes. Jane smirked when she felt him twitch inside her—wet heat gushed around his shaft as she clenched around him deliberately. "Louder," she demanded, her voice rough as she rocked forward, letting him feel the way her swollen clit dragged against his pelvis with each torturous movement.

"I need—fuck—I need your cunt," he choked out, hips jerking upward when she finally sank down, taking him deep with a shuddering moan. Jane's thighs trembled around him as she rode him hard, her dripping folds squeezing his cock in rhythmic pulses that matched the frantic roll of her hips. "There—yes—right there!" she gasped, her nails raking down his chest as her orgasm ripped through her.

Billy groaned when her cunt clenched around him like a vise, her inner walls fluttering in erratic spasms as she came with a broken cry. Hot liquid gushed around his shaft, coating his balls as she ground against him, milking every last drop from his throbbing cock. "Come inside me," she panted, her voice raw—her hips moving faster now, chasing her own pleasure even as she demanded his.

His vision whited out when he obeyed, his hips jerking upward as his cock pulsed deep inside her slick heat. Jane moaned when she felt him spill his incestuous seed inside her—her thighs tightened around his hips, forcing him deeper as she rode out both their aftershocks. "Fuck, yes," she breathed, her nails digging into his shoulders while her cunt continued to milk him, squeezing out every last drop until he whimpered from overstimulation.

She collapsed forward with a satisfied sigh, her sweat-damp skin sticking to his chest as her breath fanned across his collarbone. Billy could feel his softening cock still twitching inside her, her swollen folds clenching around him reflexively whenever he shifted. Jane nuzzled against his throat, licking the salt from his skin before biting down hard—her teeth left angry red marks that throbbed in time with his heartbeat.

Their mingled fluids leaked between them, warm and sticky as she lifted herself just enough to watch his cum dribble from her well-used cunt onto his stomach. “Messy little brother,” she murmured, dragging two fingers through the mess before pressing them against his parted lips. His tongue darted out instinctively, lapping up their combined taste—bitter-salty with the sharp tang of her arousal—as she watched through heavy-lidded eyes.

Jane shifted back slightly, her thighs trembling as she ground her swollen clit against his softening cock. The friction drew a broken whimper from her throat—her oversensitive body shuddering through another miniature climax that made his spent cock twitch inside her. “Still feel you,” she breathed, rolling her hips in slow circles while his cum seeped between them with every movement.

Her palm pressed against his chest—not pushing him away, but asserting control—as she finally lifted herself off him with a slick sound. Billy winced at the sensitivity, but Jane barely spared him a glance as she swung her legs over the edge of the bed. “Clean yourself up,” she muttered, tossing the damp towel from earlier onto his stomach without looking back.

The air between them cooled instantly, her dismissal sharper than the bite marks she’d left on his skin. Billy watched her pad across the room, her bare feet silent on the floorboards, her damp hair clinging to the sweat-slick curve of her spine. She didn’t pause at the door, didn’t glance over her shoulder—just vanished into the hallway as if he were nothing more than a discarded sex toy.

He lay there, his cock sticky and spent against his thigh, the scent of their coupling thick enough to taste. The towel she’d tossed at him lay crumpled on his chest, still warm from where it had dried her skin earlier. Jane’s indifference cut deeper than her nails ever had; the way she’d withdrawn all at once, like flipping a switch, left him hollowed out and aching.

The bedroom door clicked shut behind her with finality—no lingering glance, no whispered promise of next time, but he knew there would be a next time. His sister was a slut who couldn't get enough cock. Billy stared at the ceiling, the towel untouched as cum dripped down his thigh. Her scent clung to the sheets, to his skin, thick with the musk of their reckless fucking. He could still feel the ghost of her thighs clamping around his head, the sting of her nails raking his back—marks of their secret trist she wouldn’t acknowledge tomorrow over breakfast.

Down the hall, the shower hissed to life again. Jane would scrub away every trace of him before slipping back into her own bed, pristine as if she hadn’t just milked him dry twice. It was routine by now—the way she took what she wanted, then pretended he didn’t exist until her next whim struck. Billy pressed his palms against his closed eyes, the ache in his groin dull but persistent. She’d left him swollen and oversensitive, his cock twitching pathetically against his stomach as if still seeking her heat.

The towel lay where she’d tossed it, stiffening as their fluids dried into the fabric. He reached for it mechanically, wiping the sticky mess from his thighs, his movements sluggish. The scent clung stubbornly—musk and salt and something distinctly Jane—filling his nostrils each time he shifted. Outside, a floorboard creaked under her weight, followed by the soft click of her bedroom door. No goodnight. No acknowledgment. Just silence.
