Sister Ruins Him

2:06 a.m.

Jessica didn’t wait for anyone to decide.

“I’m going first.”

She was already shoving the standard-issue shorts down her thighs. The nineteen-inch cock sprang free with a heavy, weighted bounce, already thickening fast, the massive flare under the head swelling until it looked almost grotesque—nearly two and a half soda cans across at its widest point, the skin stretched shiny and tight. Melon-sized balls hung low and full, the skin drawn smooth with pressure. A thick bead of precum welled at the tip, stretched downward in a long clear strand, then broke and spattered loudly on the floor between her feet.

Ashley’s face went pale. “Jessica, wait—look at the size of that flare. You can’t just shove that into someone. It’s going to—”

A soft, insistent alarm chimed from the nurse’s tablet.

The nurse frowned, tapped the screen, then tapped it again harder. Her expression tightened into something closer to real concern. “Hold on. Interface just threw a critical error code. Recovery protocol is completely offline. Self-repair functions are locked out until mainland maintenance can remote in. Current estimated window is seventy-two hours minimum. Possibly longer depending on queue.”

Carson’s heart slammed against his ribs so hard he felt it in his throat and the base of his skull.

Error. Offline. They have to stop. They have to cancel the session. The second this feed ends I can call the number on the discharge sheet. I can terminate the trial. I can make them cut the connection and remove the ring. I can still walk away from this and pretend none of it ever happened. I can still—

On the feed the nurse lowered the tablet and muttered, almost to herself but still perfectly audible through the headset, “Might actually be better if the new girl gets taken care of anyway. Last thing this wing needs is an extreme presentation with balls that full climbing the walls and hurting someone. Safety of the island comes first. Always. One ruined mainland endpoint is preferable to an incident here.”

She looked up at Jessica, then at the camera lens, then back at Jessica.

“Go ahead. Worst case we put in a request for a replacement endpoint later. If anyone stateside asks, we never saw the error code. Official log will show a clean, uneventful session. Understood?”

Jessica’s smile was immediate, bright, and openly predatory.

“Perfect.”

Ashley grabbed her daughter’s arm hard enough that her knuckles whitened. “No. We just got here. I don’t want to break anything permanently. What if it damages the system beyond repair? What if the person on the other side is left open for days— Jessica, look at you. That flare alone is bigger than most of the cocks on this island. You’re going to tear him apart. You’re going to ruin him.”

Jessica turned and softened her voice in the exact way she used to when she wanted something at home and knew precisely which buttons to press.

“Mom. Listen to me carefully. We’re never going home. You heard the intake people. Research could take years. Decades, even. Carson’s going to move on. He’s going to get some boring job and find some boring wife and have boring little kids and forget we ever existed. That’s what people do when family disappears overnight. He’ll cry for a week and then he’ll start scrolling job boards again and eventually he’ll stop mentioning us. But this?” She gestured at the mount and the camera with her free hand; the nineteen-inch cock bobbed heavily with the motion, the massive flare catching the overhead light. “This worthless cumdump is about to have his hole permanently destroyed. He’s never going to be able to think about anything except my cock for the rest of his life. At least someone will remember us. At least someone will carry the exact shape of me inside them forever. Isn’t that better than being completely forgotten by our own family?”

Ashley’s mouth opened. Closed. The thick, downward-curving cock between her own legs twitched hard against her will, a fresh, heavy bead of precum sliding down the shaft and dripping onto the floor in a clear strand. She looked at the camera—at the feed she still believed belonged to a complete stranger—and the fight drained out of her shoulders in a visible, defeated wave.

“…Fine. Just— don’t be needlessly cruel about it. Please.”

Jessica’s smile widened until it showed teeth.

“No promises.”

She climbed onto the mount with easy, practiced confidence, the heavy swing of her cock and balls making the motion look almost indecent.

Carson watched the nineteen-inch shaft rise into full, brutal hardness. The flare under the head looked even more obscene up close, the skin stretched shiny and tight, already wet with a continuous bead of precum. He felt the first blunt, massive pressure kiss the ring of his asshole and every muscle in his body locked so hard his teeth clicked together and his fingers dug into the sheets hard enough to hurt.

They’re still doing it. The error doesn’t matter to them. They’re going to let her put that thing inside me knowing the recovery system is dead. They’re going to let her break me on purpose—

Jessica lined up, gripped the supports with both hands, and pushed with steady, relentless, unstoppable force.

The head met resistance and kept coming. The flare was simply too wide. Carson felt the ring of muscle stretch and stretch and then begin to burn as the thickest part of the ridge forced against it. The pressure climbed past anything the earlier session with his mother had prepared him for—past discomfort, past pain, into a bright white territory that made his vision tunnel and his breath stutter. Jessica’s face on the feed was focused, almost clinical, and then openly, viciously pleased when the resistance finally began to yield under the continuous pressure.

The flare punched through with a wet, brutal, audible pop that Carson felt as a white-hot tear of sensation deep in his core.

He screamed into the mattress, the sound muffled and completely useless.

The rest of the shaft followed in one continuous, merciless drive. Nineteen inches of dense, heavily veined cock forced into him until the massive flare locked deep against his furthest point and her melon-sized balls slapped flush against the interface with a heavy, final, meaty thud. The stretch was immediate and total. His hole felt like it had been forced open past any natural or unnatural limit, the rim burning in a perfect, overstretched circle of tissue. The downward pressure of the flare crushed his prostate so completely that his vision whited out at the edges and his own cock jerked hard, spilling a thick, involuntary spurt across the sheets in a long, shameful, unbroken pulse.

Jessica let out a long, low, deeply satisfied moan that vibrated through the feed.

“Oh my fucking god. It’s so tight. Brand-new and already shaking around me like it can’t believe what’s inside it.” She rolled her hips in a slow, grinding circle, deliberately dragging the oversized flare across the deepest tissue in a way that made Carson’s toes curl and his breath hitch in his throat. “Listen to that, Mom. It’s fluttering like it’s trying to push me out. It can’t. There’s nowhere for it to go. I’ve got every single inch of this soft little fuck-sleeve completely filled and claimed. It’s mine now.”

Ashley stood a few feet away, arms wrapped tightly around herself, her own thick cock still rigid and steadily leaking onto the floor in clear droplets. Her voice came out quiet and strained. “Jessica, please don’t hurt it more than you have to. The recovery is offline. If you push too hard—”

“Hurt it?” Jessica laughed, the sound bright and mean, and pulled back halfway. The thick shaft dragged free with a long, wet, filthy schlick, the massive flare catching hard on the rim and forcing another burning, reshaping stretch before she slammed home again with her full weight.

THUD.

Carson’s entire body jerked as if he’d been struck. The connection held him locked in place; there was nowhere to go, no way to crawl forward, no way to close. He could feel every ridge, every thick vein, the exact impossible shape of the oversized flare as it scraped his walls raw on the way in and out. His own cock was rock-hard and constantly leaking now, a steady thin string of fluid already soaking a dark, spreading patch into the sheets beneath him.

It’s too big. It’s too big it’s too big it’s too big it’s going to split me open and she’s going to keep going anyway—

Jessica set a rhythm immediately. No warm-up. No mercy. Full-length strokes that dragged the flare from the deepest point all the way to the rim and then forced it back through in one continuous, punishing thrust that made the entire mount creak under the force.

Schlick-THUD.

Schlick-THUD.

Schlick-THUD.

“Feel that, you pathetic contract hole?” she said directly to the camera, voice bright and mean and already a little breathless with rising pleasure. “That’s me breaking you open. I’m going to stretch this hole so wide it never closes right again. You’re going to be my personal fucksleeve. Every time you sit down, every time you walk, every time you try to clench, you’re going to feel the exact shape of my cock and remember who owns this cunt now. Say it in your head for me. ‘This hole belongs to Jessica.’ Say it, you disposable little cumrag.”

Carson’s internal voice was a broken, looping scramble of denial and raw, overwhelming sensation.

She’s not talking to me. She doesn’t know it’s me. This is still a stranger to her. I can still get out of the contract the second this ends. I can still call the number. I can still make them cut the connection. I can still walk away and never think about this again. I can still—

The flare dragged across his prostate again with deliberate, crushing, grinding pressure and his cock jerked hard, spilling another thick, helpless spurt across the sheets. He couldn’t stop it. The pressure was constant, overwhelming, and every full stroke forced another involuntary pulse of fluid out of him. His thighs had begun to tremble uncontrollably. The stretch burned in a deep, continuous, reshaping way that felt like it was permanently rewriting the limits of his body from the inside out.

Jessica noticed the way the interface seemed to flutter and clench desperately around her and grinned wider, teeth flashing in the bright overhead lights.

“Oh, the loser just came again. Already. From nothing but getting his hole broken open on my cock. What a perfect, soft little fucktoy. Keep leaking for me. I want that mattress completely soaked by the time I’m finished with you. I want you dripping my precum and your own cum until you can’t tell which is which and you stop caring about anything else.”

Ashley’s voice was tighter now, edged with reluctant, unwanted heat. “Jessica, the error—what if it really can’t recover after this—what if the person on the other side is left permanently open and leaking—”

“Then he’ll stay open.” Jessica slammed in particularly hard. The wet, heavy slap of her melon-sized balls against the mount was loud enough to make the nurse flinch and take half a step back. “That’s the entire point, Mom. I’m going to make sure this hole never forgets me. He’s going to be ruined for anything else for the rest of his life. Fingers, toys, normal cocks, even someone else’s big dick—nothing will ever feel like enough after this. Only me. Only my cock. Only this flare stretching him open until he can’t remember what being closed felt like. You might have been better off if a full-size breeding horse fucked you. At least then you’d have an excuse for how completely destroyed you’re about to be. He’s going to spend the rest of his life chasing this exact feeling and never finding it again. That’s the gift I’m giving him. That’s what he signed up for when he offered this ass.”

Carson felt the words land somewhere deeper than the physical violation, somewhere under the burning stretch and the constant, bruising pressure on his prostate.

Only her cock. She’s saying I’ll only be able to cum from her cock after this. She’s saying I’m going to be ruined for anything else. She’s saying this is permanent. She’s saying I asked for it—

The next thrust drove the half-formed thought out of his head in a white flash of pure, overwhelming sensation. The flare was so wide it forced his walls into a constant, burning, reshaping stretch that never lessened even for a second. He could feel the exact moment the thickest part of the ridge passed the rim on every single stroke—an intense, almost nauseating pop of pressure followed by the long, heavy, inescapable slide of the remaining shaft. His prostate was being battered without rest or relief. His cock had not softened once since the first insertion; it stayed rigidly hard and constantly dripping, the thin string of fluid now continuous and shameful and impossible to stop.

Jessica’s commentary never slowed, never softened, never gave him a moment’s peace.

“You’re taking me so well for a money-signed cumdump. Nineteen inches and this fat fucking flare and you’re still trying to grip me like you think you can keep me out. I can feel every little desperate flutter. Keep trying to close. It makes it so much better when I force it open again and again and again.” She laughed, the sound bright and cruel and breathless with rising pleasure. “I’m going to pump so much cum into you that your stomach swells up like you’re pregnant with it. You’re going to look ridiculous. And every time it leaks out of this ruined hole you’re going to remember exactly who put it there and exactly how it felt going in and exactly how little choice you had about any of it. You were better off as breeding-stock than whatever sad little life you had before.”

Ashley had one hand wrapped around her own thick, downward-curving cock without seeming to realize she was doing it, stroking slowly as she watched her daughter work. Her voice was quieter, almost to herself, and full of a strange, guilty, unwanted heat.

“Carson’s probably asleep right now in that house. Or staring at that laptop again like he always does. He doesn’t even know we’re really gone, not deep down. He doesn’t know any of this is happening. He’s just… alone in that quiet apartment thinking we might still come back someday.”

Jessica’s rhythm stuttered for half a second at the sound of her brother’s name, then grew deliberately rougher, meaner, more punishing.

“Good. Let him forget us. Let him move on and have his boring little life with his boring little job and his boring little wife. This soft, open hole won’t forget. This bitch is going to feel me every time he tries to sit down for the rest of his life.” She drove in to the root and stayed there, grinding the massive flare in tight, punishing, circular motions against Carson’s deepest point until his vision sparked white. “You hear that, loser? My brother’s going to get some ordinary job and some ordinary wife and forget his family ever existed. You’re going to stay broken open on my cock. That’s the difference between him and a proper fuckhole. He gets to move on. You get to be mine. Permanently. Every day. Every night. Every time you leak. You might as well have let a breeding stallion have you—at least then the damage would make sense.”

Carson’s denial cracked clean down the middle with an almost audible internal sound.

She’s talking about me. She’s using my name while her cock is inside me. She’s comparing me to the stranger she thinks she’s fucking and she’s saying the stranger is better than me because the stranger is getting ruined by her. She’s saying I’m the kind of person who would be forgotten and this hole is the kind that gets kept and used and broken—

The physical reality crashed back in as Jessica resumed the full, punishing, full-length strokes. The wet sounds were continuous now, thick and filthy and rhythmic and inescapable.

Schlick-thud-schlick-thud-schlick-THUD.

Schlick-thud-schlick-thud-schlick-THUD.

Schlick-thud-schlick-thud-schlick-THUD.

His belly had begun to firm from the constant flood of thick, hot precum her cock was forcing deeper into him with every thrust. The heat of it sat heavy and low, and every new stroke pushed more inside until he could feel the weight beginning to settle and shift. His hole felt raw, overstretched, the rim burning in a continuous circle of sensation every time the flare dragged through it. He could no longer tell where the stretch ended and the deep, bruising, permanent-feeling ache began. His cock kept leaking in helpless, rhythmic pulses timed exactly to the deepest impacts of the flare against his prostate. The sheets beneath him were already soaked through in a dark, spreading stain.

Jessica’s breathing grew sharper, more ragged, more openly pleasurable.

“I’m getting close. First load of many, you permanent soft cunt. You’re going to take all of them. I’m not pulling out until these balls are completely empty. You’re going to be so full of me you’ll feel it when you breathe. You’re going to feel it in your throat. You’re going to feel it every time you move for days. You’re going to feel me.”

She slammed in one final time with her entire weight and stayed buried to the hilt, the flare locked deep and unmoving.

The first pulse of her orgasm hit like a high-pressure hose turned on full force.

Carson’s eyes flew open behind the headset. Thick, scorching, heavy cum flooded into him with so much force that his belly rounded in visible, real-time increments. Jessica kept cumming—long, dense, powerful ropes that forced his guts outward until the skin of his stomach stretched shiny and tight and began to ache with the pressure. The volume was absurd, impossible, continuous. He could feel every distinct spurt as a heavy, hot, claiming impact deep inside him.

Glurrk-churn—

Glurrrk-churrrn—

Glurrrrk-churrrrn—

Glurrrrrkk-churrrrrn—

Jessica moaned loud and open and almost triumphant, hips locked and grinding in short, brutal circles as she emptied herself in heavy, rhythmic, seemingly endless pulses.

“Take it—take every fucking drop—this hole is mine now—you’re my broken little fucktoy—you’re never closing again—you’re never going to forget this—”

Carson’s own cock jerked violently and spilled again, completely untouched, the orgasm torn out of him by the crushing, continuous pressure of the flare against his already-abused prostate and the impossible, stretching fullness spreading through his belly. Tears streamed freely out from under the headset padding and tracked down his temples into his hair. His internal voice had gone fragmented and thin and frightened and dangerously close to something darker.

She’s filling me. My sister is filling me and she doesn’t know it’s me and I can’t stop it and it feels like it’s never going to end and she’s saying I’m hers and part of me is starting to believe her and I don’t know how to make it stop—

Jessica’s first orgasm finally began to taper after what felt like an eternity of continuous, heavy pulsing. She did not pull out.

She stayed locked to the root, breathing hard, cock still fully hard and twitching inside him, and after only a few seconds of recovery she began thrusting again—shorter, meaner, more grinding strokes that kept the massive flare dragging back and forth across the same bruised, oversensitive, swollen spots without mercy.

“Still hard,” she panted, voice rough with open pleasure. “Still full of cum for you. You’re not done, you leaking fuck-sleeve. Not even close. I’m going to keep you stretched open around me until there’s nothing left in these balls. Until you’re so full you can’t take another drop and I make you take it anyway. Until this hole learns its only purpose is taking my cock.”

Ashley watched with wide, conflicted eyes, one hand still slowly stroking her own thick cock in time with her daughter’s thrusts. Her resistance was visibly crumbling. “Jessica… the amount you’re putting in him— the error— what if the recovery really never comes back online— what if he’s left like this forever—”

“Then he stays like this.” Jessica’s voice was fierce with open, vicious enjoyment. “Open. Full. Ruined. That’s what the system is for. That’s what he’s for. A loser who signed a paper and offered his ass up so girls like us could finally break something the way we needed to. The way we deserved to after everything. A breeding-horse would have been kinder to him than I am.”

She fucked him through a second full, extended orgasm without ever fully leaving the hole. The new load had nowhere regulated to go; Carson’s belly swelled further, the weight of it pulling downward until every breath was shallow and labored and the skin felt ready to split. Thick cum began to leak out around the shaft in steady, forced pulses, pushed past the seal of the flare by the sheer volume already packed inside him. The wet sounds turned louder and filthier, a constant, rhythmic, obscene schlick-glurrk-schlick-glurrk-schlick-glurrk as her cock churned the growing mess of her own cum inside him.

Carson’s thoughts had started to slip their moorings completely.

She’s right. I signed the contract. I took the money. I let them put the ring in me without reading every line. I am the loser she keeps calling me. I am the hole. I am the soft, ruined thing she’s breaking open. I am the one who will never close again. I am the one who asked for this without knowing what I was asking for—

He tried to drag the denial back up one last time and failed. The physical reality was too complete, too overwhelming, too total. Nineteen inches of his sister’s cock was rearranging his insides with every stroke. The flare had stretched him past any point of recovery he could imagine possible. His prostate felt bruised and swollen and permanently oversensitive; every pass of the thick ridge forced another helpless spurt of fluid from his constantly leaking cock. The sheets beneath him were soaked through in a dark, spreading, shameful stain that had reached the edge of the mattress. His belly was a taut, rounded, glossy dome that visibly shifted and swayed with every thrust.

Jessica’s third orgasm hit harder and lasted longer than the first two combined.

She buried herself to the balls with a final, vicious, claiming thrust and roared, hips locked in place as thick, heavy, seemingly endless pulses pumped into the already overloaded space. Carson felt his stomach stretch to a painful, shiny, impossible tightness. Cum poured out around her cock in thick, continuous ropes, completely unable to stay contained. The heat of it was everywhere—deep in his guts, forcing its way out around the shaft, leaking down the backs of his thighs in warm streams, soaking into the mattress in a growing pool that reached his knees and kept spreading.

When the last powerful pulses finally faded, Jessica still did not pull out.

Instead she began the real destruction.

She pulled back slowly until only the massive flare remained inside him, stretching the entrance wide open, and then she started grinding it in slow, deliberate circles right at the rim. The thickest part of the ridge rubbed continuously against the most sensitive ring of muscle, over and over, with no full strokes to give any relief. Carson felt the entrance being worked into something soft and loose and permanently changed. The burn was different now—deeper, more specific, focused entirely on the place that was supposed to be able to close.

Jessica’s voice stayed calm and almost instructional.

“Feel that, you permanent open hole? That’s me softening the entrance. I’m going to keep the flare right here until this rim forgets how to hold any shape at all. You’re going to stay open because I’m making sure of it.”

She kept the grinding going for a long time, narrating every small change she felt.

“It’s already softer… the grip is almost gone… I can feel it giving up around the flare… good livestock… soft livestock…”

Then she drove all the way back in to the root and locked herself there, using her full weight to keep the flare pressed as deep as it could go. She stayed like that, unmoving except for small, grinding circles, and began talking to the camera in a low, steady voice.

“This is the deepest I can get. This is where the flare sits when I decide you don’t get to feel empty. You’re going to remember this pressure every time you try to sit down. Every time you try to clench. Every time you leak.”

She turned her head slightly toward Ashley without pulling out.

“Mom. Look at it. Tell the camera what you see.”

Ashley hesitated, still slowly stroking herself, then stepped closer and looked down at the place where her daughter disappeared into the interface. Her voice came out quiet and defeated.

“It’s… completely stretched. The rim is just… open around you. It’s not fighting anymore. This person’s asshole is definitely ruined.”

Jessica smiled and kept the deep, grinding pressure going for another full minute, making sure the last thing the hole felt before the exit was the flare locked as deep as possible while her mother confirmed the damage out loud.

Only then did she begin to pull out.

She did it as slowly as she could, letting the massive flare catch and drag every inch of the way. The exit itself became another layer of damage. When the ridge finally popped free with a loud, wet, obscene sound, a true flood of thick cum followed—heavy, creamy, continuous ropes that poured from the gaping opening in a steady, unstoppable stream. Carson felt the sudden, catastrophic emptiness and the immediate, overwhelming gush of fluid leaving him. His hole stayed wide open, the rim stretched into a dark, ruined, glistening circle that showed no sign of closing. Cool air touched the inside of him and the sensation made him shudder hard.

Jessica did not step away.

She stayed right there, reached down with both hands, and spread the gaping hole open with her fingers so the camera—and Ashley and the nurse—could see exactly how destroyed it was. Cum continued to pour out around her fingers.

“Look at that,” she said, voice calm and satisfied. “No resistance left. Just a soft, open, ruined fuckhole. Come here, Mom. Feel it.”

Ashley hesitated only a second longer, then reached out and pressed two fingers into the open, cum-slicked entrance. Her expression flickered with something between horror and heat as she felt how easily they sank in and how little the muscle tried to close around them.

The nurse stepped closer as well, tablet still in hand, and spoke in a low, fascinated voice.

“Complete loss of resting tone. No spontaneous closure. Endpoint is effectively non-functional for anything except high-volume use. Whoever is on the other side is going to need significant management going forward.”

Jessica kept the hole spread with one hand and looked straight into the camera.

“You hear that, you broken little cumdump? You’re ruined. Permanently. That hole is staying open. Every time you move you’re going to feel cool air on the inside of you. Every time you try to clench, nothing is going to happen. You’re just a gaping, cum-leaking, ruined fucktoy now.”

Ashley withdrew her fingers slowly, looked at the continuous leak, and then looked directly into the camera with a quiet, almost gentle finality.

“It looks like my daughter ruined you,” she said. “Let’s just hope this is what you wanted. You must just be some horny, useless loser who signed his ass away for money. I hope it was worth it. Because that hole is never closing again.”

She paused, still looking into the lens, and added in the same calm, tired voice:

“You’re probably going to want to start wearing a diaper. For the rest of your life. There’s no way that stays clean or contained after what she just did to you. Just accept it. This is your body now.”

Jessica smiled, bright and mean and completely unrepentant, and gave her cock another slow, possessive stroke as she looked at the permanently gaping, cum-drenched, ruined hole.

“Good. That’s exactly what I wanted. A hole that will never forget me. A soft, open, ruined livestock hole that will never close again. A loser who finally found his purpose. And now even my mom agrees you should just diaper up and stay open for whatever comes next.”

She glanced at her mother, then at the nurse, then back at the camera with final, claiming satisfaction.

“You’re mine now, loser. That ass belongs to me. And the next time I get a turn on this system, I’m going to make absolutely sure it never, ever closes again. I’m going to keep you open and full and leaking until you forget you ever had any other purpose except taking my cock and my cum. You’re just a gaping, ruined, cum-leaking, diaper-wearing fuckhole now. And everyone here knows it.”

Carson lay in the dark bedroom with the headset still sealed over his eyes, unable to look away, unable to move, unable to close.

His belly was grotesquely swollen, the skin stretched tight and shiny and aching with the weight of everything she had left inside him. Thick cum continued to leak in a steady, unstoppable stream from a hole that would not close no matter how weakly the malfunctioning ring tried to pulse. His prostate felt bruised, swollen, and permanently oversensitive; the slightest shift of his hips sent fresh, unwanted, electric sparks of sensation through his entire lower body. His cock was still hard, still constantly leaking, a continuous thin string of fluid connecting the tip to the completely soaked sheets. Cool air moved inside him with every breath.

The denial had run out completely.

Somewhere under the wreckage of physical sensation and the lingering, echoing sound of his sister’s voice—and his mother’s quiet, practical recommendation about the diaper—a thin, terrible, seductive thought had taken root and begun to grow in the dark.

She’s right.

I’m never going to be the same.

This hole is hers now.

I am hers now.

I signed the paper. I took the money. I let them put the ring in. I am exactly the worthless, soft, ruined thing she said I was.

And I’m going to need a diaper.

The feed stayed open.

Jessica was still looking directly into the camera, still slowly stroking her cum-slicked cock, while her mother and the nurse both stared at the permanently gaping, cum-drenched, ruined hole that had once been his and would never close again.
