Girlfriend Taken by Neighbor’s Huge Cock While I Watched

The afternoon sun slanted through the thin curtains of the small off-campus apartment, painting lazy stripes across the scuffed hardwood floor. Mark sat on the edge of the couch, still in his work jeans and a faded university hoodie, the faint smell of coffee and exhaust clinging to him from the café shift he had just finished. At twenty-seven he carried himself with the quiet confidence of a man who had always been told he was enough—solid build from years of lifting, a thick seven-inch cock that had never failed to make Lisa moan, and a face that still earned second glances from girls on campus. Lisa, twenty-four, was stretched out on the opposite end of the couch in nothing but one of his old T-shirts that barely covered the tops of her thighs. Her blonde hair was piled in a messy knot, a few strands sticking to the sweat at her neck. She had the kind of body that made strangers stare: full C-cup tits that sat high and firm, a narrow waist that flared into hips made for gripping, and an ass that bounced when she walked. Her pussy was smooth, pink, and tight enough that Mark still had to work to get all the way inside on the first thrust.

They had been living together for eight months, fucking almost every night, and Mark genuinely believed she was satisfied. He had no idea how wrong he was.

The pounding on the door was loud enough to rattle the cheap hinges. Mark groaned. “Jesus Christ, not again.”

Lisa rolled her eyes but didn’t move. “It’s that little shit next door. Tell him to turn the bass down before I go over there and shove his speakers up his ass.”

Mark opened the door and found Tyler leaning against the frame like he owned the building. Nineteen, barely five-foot-seven, scrawny in a way that made his baggy basketball shorts look ridiculous, baby-faced with a perpetual smirk. The kid’s parents paid the rent; everyone on the floor knew it. He played music at all hours, hit on every girl in the complex, and somehow never got kicked out.

“We need to talk, bro,” Tyler said, stepping inside without invitation and shutting the door behind him.

Mark’s jaw tightened. “About the music. Yeah. Keep it the fuck down.”

Tyler’s eyes flicked past him to Lisa, who had sat up, the T-shirt riding higher on her thighs. “Nah. About your girl.”

Lisa’s laugh was sharp. “Excuse me?”

Tyler didn’t look at Mark. He looked straight at her. “I want to fuck you. Been wanting to since you moved in. And I think you want it too.”

The silence that followed was thick enough to choke on. Mark felt heat rise up his neck. “Get the fuck out.”

Lisa stood, arms crossed under her tits, the thin cotton pulling tight across her nipples. “You’re a child. A loud, annoying child. Go home.”

Tyler’s smirk only widened. “I got a bigger cock than your boyfriend. Bet you anything.”

Lisa’s eyes narrowed, then flicked to Mark with a spark of something he couldn’t read—challenge, curiosity, maybe both. “Prove it, then. Right now. Whip it out, little boy. Let’s see that ‘bigger cock’ you’re so proud of.”

Mark’s stomach dropped. “Lisa—”

“No,” she cut him off, voice bossy the way it always got when she decided something. “He’s been running his mouth for months. Let’s embarrass him and be done with it.”

Tyler was already untying the drawstring of his shorts. Mark felt his own hands move on autopilot, unbuckling his belt, shoving his jeans and boxers down. His cock hung semi-hard, the familiar seven inches looking solid in the afternoon light. He glanced sideways—

And the world tilted.

Tyler’s cock was already thick and heavy, hanging halfway down his thigh even soft. The head was the size of a plum, the shaft veined and girthy like a soda can, the balls heavy and full beneath. As Lisa stared, it began to swell, lengthening, thickening, until it stood out from his skinny body like a third leg—easily eleven inches, maybe more, thicker than Mark’s wrist.

Lisa’s breath hitched. “Holy… fuck.”

Mark’s face burned. His own cock looked almost cute next to that monster. He wanted to pull his pants up, to shove Tyler out the door, but Lisa was already stepping closer, eyes locked on the heavy meat swaying between the kid’s legs.

“Touch it,” Tyler said, soft and certain.

She did. Both hands wrapped around the shaft and still couldn’t close. The skin was hot, the veins pulsing under her fingers as it finished hardening. A thick bead of precum welled at the slit and dripped onto her thumb. Lisa’s thighs pressed together. Mark could smell her—sweet, musky arousal already blooming between her legs.

“It’s… Christ, Mark, look at it. It’s huge.” Her voice had gone husky. She stroked slowly, feeling the weight, the heat. “I’ve never seen anything like this.”

Tyler’s hand settled on the back of her head. “Suck it, slut. Show your boyfriend how a real cock gets treated.”

Lisa dropped to her knees without another word. Mark stood frozen three feet away, cock twitching traitorously as his girlfriend opened her mouth as wide as it would go and took the massive head between her lips. Her jaw strained. Spit immediately spilled from the corners of her mouth. She worked the first four inches in, tongue swirling, cheeks hollowed, then gagged hard when Tyler pushed deeper. Tears pricked her eyes. Mascara started to run.

“That’s it,” Tyler groaned. “Open that throat. Your boyfriend’s little dick never stretched you like this, did it?”

Lisa moaned around the cock, the vibration making Tyler’s hips jerk. She bobbed faster, spit-soaking the shaft, one hand pumping what she couldn’t fit, the other cupping his heavy balls. Mark watched her throat bulge every time she forced herself lower. She pulled off with a wet gasp, strings of saliva connecting her lips to the shiny head.

“It’s so fucking thick,” she panted. “Mark… I can’t even get half of it in. Fuck.”

Then she went back down, determined, choking herself on it while Tyler held her hair and fucked her face in short, brutal strokes. Mark’s cock was fully hard now, leaking, and the humiliation only made it throb harder. He stroked himself slowly, unable to look away as his perfect girlfriend turned into a drooling, mascara-streaked mess for a nineteen-year-old’s monster cock.

Tyler finally pulled her off by the hair. Her lips were swollen, chin shiny with spit and precum. “Bedroom. Now. I want that tight cunt.”

Lisa stood on shaky legs, peeled the T-shirt over her head, and walked naked toward their bedroom, hips swaying, pussy visibly dripping down her inner thighs. Tyler followed, cock bobbing heavily. Mark trailed after them like a ghost, heart hammering, cock in his fist.

In the bedroom Tyler shoved her onto the mattress. Lisa spread her legs immediately, pink folds glistening, clit swollen. Tyler climbed between them and laid his cock along her stomach. The head reached past her navel. The visual was obscene—her tiny body under that massive rod.

“Put your head here,” Tyler ordered Mark, pointing to Lisa’s lower belly. “I want you to watch every inch stretch your girlfriend open.”

Lisa’s hand found Mark’s hair and pulled him down until his cheek rested on her soft skin, eyes inches from her dripping pussy and the fat cockhead pressed against it. “Do it,” she whispered, almost pleading. “I need it. Please.”

Tyler pushed.

The head stretched her entrance obscenely wide. Lisa’s mouth fell open in a silent scream. Mark watched the thick shaft sink in, inch by thick inch, her lips gripping it, her belly rising under his cheek as she was forced to take more than she ever had. Wet, filthy sounds filled the room—her cunt squelching, her broken moans, the wet slap of Tyler’s hips finally meeting hers when he bottomed out.

“Fuuuuck—oh my god—it’s so deep—” Lisa’s voice cracked. Her nails dug into Mark’s scalp, holding him in place. “I can feel it in my stomach—Mark—look—”

Tyler started thrusting. Long, powerful strokes that dragged almost all the way out before slamming back in. Lisa’s tits bounced. Her eyes rolled. Within a minute she was cumming hard, pussy convulsing around the massive invader, juices spraying Mark’s cheek. Tyler didn’t stop. He fucked her through it, then flipped her onto all fours and mounted her from behind, hands on her waist, pounding her so hard the headboard slammed the wall.

Mark knelt at the side of the bed, stroking himself, watching his girlfriend’s face contort in pure, mindless pleasure. She looked back at him once, eyes glassy, and moaned, “He’s so much bigger… I can feel every vein… fuck, Mark, I’m never going to be the same—”

Tyler reached under her, rubbed her clit, and she came again, screaming into the pillow. Then he pulled out, shiny and dripping, and pressed the head to her tight asshole.

“No—wait—I’ve never—” Lisa started, but Tyler was already pushing. The tight ring stretched, resisted, then gave. Lisa howled as the thick cock forced its way into her ass, slow and relentless until his hips were flush against her cheeks. Mark watched the impossible sight of that huge shaft disappearing into his girlfriend’s formerly virgin ass. Tyler fucked it just as hard, and Lisa’s screams turned into broken, ecstatic sobs.

When Tyler finally came, he buried himself to the hilt in her ass and flooded her with thick ropes of cum. Mark saw the excess leak out around the shaft, white and heavy, dripping onto the sheets. Tyler pulled out with a wet pop; Lisa’s ruined holes gaped, both leaking his load.

She collapsed onto her stomach, trembling, a fucked-out mess. Tyler wiped his cock across her cheek, smearing cum and spit, then looked at Mark.

“Clean her up, cuck. Lick every drop out of her. She belongs to this cock now.”

Lisa turned her head, eyes half-lidded, and whispered, “Do it, baby. Taste him. Taste what a real man put inside me.”

Mark’s face burned, but his cock was harder than it had ever been. He crawled between her spread thighs and pressed his tongue to her dripping, gaping cunt. The taste was thick, salty, foreign—Tyler’s cum mixed with her juices. He licked deeper, sucking, swallowing, while Lisa moaned and pushed back against his face. Then he moved to her ass, tongue delving into the stretched, cum-filled hole, cleaning every trace while she shuddered through another small orgasm.

Tyler sat on the edge of the bed, already half-hard again, watching. “Good boy. Now watch me fuck her again.”

The second round lasted longer. Tyler made Lisa ride him reverse so Mark could see every thick inch stretching her pussy from below. He made her suck his cock clean after every position change. He fucked her tits, her mouth, her cunt, her ass again, filling each hole with another massive load. By the time the sun set, Lisa was a wreck—body marked with handprints, holes leaking, voice hoarse from screaming. Mark had cum twice just from watching and cleaning, his own seed mixing with Tyler’s on the sheets.

When Tyler finally left, he slapped Lisa’s ass one last time and said, “I’ll be back tomorrow. Keep her wet for me.”

Lisa lay in the middle of the ruined bed, staring at the ceiling, a soft, satisfied smile on her face. Mark sat on the floor beside her, spent, humiliated, and more aroused than he had ever been in his life.

She reached down and stroked his still-sensitive cock with sticky fingers. “Your little dick still feels good, baby,” she murmured. “But nothing will ever fill me like that again. You’re going to watch every time, aren’t you? You’re going to hold me open and watch that huge cock ruin me over and over.”

Mark swallowed. His answer was a broken whisper.

“Yes.”

The next afternoon Tyler didn’t bother knocking. He walked in while Mark was washing dishes and Lisa was on the couch in a tiny pair of shorts and a sports bra. She looked up, already wet, and simply spread her legs. Tyler dropped his shorts, stroked that massive cock once, and Lisa was on her knees again before Mark could dry his hands.

This time she was greedier. She deepthroated as much as she could, gagging wetly, spit pouring down her chin and onto her tits. Tyler face-fucked her until her makeup was destroyed, then bent her over the arm of the couch and slammed into her cunt in one brutal thrust. Mark stood three feet away, cock out, stroking as his girlfriend’s body jerked with every impact. The wet, meaty sounds of that huge cock rearranging her insides filled the apartment. Lisa’s eyes found Mark’s and stayed locked on him while she came, mouth open, tongue out, drooling.

“Tell him,” Tyler ordered between thrusts. “Tell your boyfriend how much better this is.”

“It’s so much better,” Lisa gasped. “Your cock is nothing—fuck—nothing compared to this. He’s stretching me so wide—Mark—I’m his now—I’m his big-cock slut—”

Tyler pulled out, flipped her onto her back on the coffee table, and folded her legs up until her knees were by her ears. He drove back in, using her like a toy, the thick shaft visible through her lower belly with every thrust. Mark dropped to his knees and licked her clit while Tyler fucked her, tasting the stretch, the heat, the way her pussy lips clung to the invading cock. When Tyler came, he pulled out and shot thick ropes across her tits and face. Lisa scooped it up with her fingers and fed it to Mark, making him suck every drop while Tyler watched, smirking.

They fucked for hours. On the floor. Against the wall. In the shower where Mark was forced to hold Lisa’s legs open while Tyler drilled her from behind under the spray. Every load ended up either inside her or on her body for Mark to clean. By nightfall Lisa could barely walk. Her pussy was puffy and red, her ass permanently stretched, her voice a rasp. She fell asleep with Tyler’s cum still leaking out of her, Mark curled beside her, one hand gently cupping her ruined cunt as if he could somehow put her back together.

He couldn’t.

Over the following weeks the dynamic solidified. Tyler came over almost every day. Sometimes he texted Lisa while Mark was at work: “Get that cunt ready. I’m using it when I get off class.” Mark would come home to find his girlfriend already bouncing on that massive cock, or bent over the kitchen counter taking it in the ass, or on her knees with her face buried in Tyler’s balls. Sometimes Tyler made Mark stay and watch the entire time. Sometimes he sent him out for food and used Lisa the whole hour he was gone, so that when Mark returned she was a cum-leaking, fucked-stupid mess who could only whimper for more.

Lisa’s dirty talk grew filthier. She would make Mark measure his cock against Tyler’s while she stroked them both. She would ride Mark’s smaller dick and complain the whole time that she could barely feel it, then climb off and sit on Tyler’s face until she came, only to beg for the real cock again. She started calling Mark “cuck” and “little dick” in bed, laughing when his cock twitched at the words. She made him buy her new lingerie specifically so Tyler could rip it off. She filmed some of the sessions on her phone and made Mark watch them later while she edged him, whispering, “Look how wide he opens me. Look how much cum he pumps into your girlfriend. You’ll never do that. Never.”

One Friday night Tyler brought a friend—another college kid named Devon, tall and lean with a cock almost as thick though a little shorter. Lisa didn’t hesitate. She sucked them both side by side while Mark watched from the corner, then took turns getting railed by both, ending up with two thick loads dripping from her pussy and one in her ass. Mark cleaned every hole while the two younger men laughed and slapped her ass, calling her their personal cumdump. Lisa came so hard from the dual attention that she cried, then pulled Mark up and kissed him deeply so he could taste both of them on her tongue.

The sex became ritual. Build-up of teasing and humiliation, Lisa’s body displayed and used, Mark’s forced participation as cleaner and witness, multiple creampies, sometimes anal, always the same massive stretching that left her walking funny the next day. She started skipping classes to stay home and recover, or to be ready when Tyler texted. Her phone was full of dick pics and video demands. Mark’s was full of the same, because Lisa forwarded everything.

One night, after Tyler had fucked her into a near-comatose state and left, Lisa pulled Mark on top of her. His cock slid into her loose, cum-slick pussy with almost no resistance. She locked her legs around him and whispered against his ear while he thrust.

“I love you. But I need that huge cock. I need to be stretched and filled and ruined. You’re going to keep watching. You’re going to keep cleaning me. And every time he fucks me, you’re going to thank him for using your girlfriend’s holes so well. Understand?”

Mark buried his face in her neck, hips moving, the wet sound of Tyler’s leftover cum squelching around his smaller cock. “Yes. Fuck—yes. Thank you for letting me watch. Thank you for letting him use you.”

She came around him, soft and rolling, and he followed, adding his weaker load to the mess already inside her. They fell asleep like that, sticky and spent, the apartment smelling of sex and sweat and the permanent presence of another man’s cock.

Months later the dynamic had only deepened. Lisa’s body had changed—her pussy stayed slightly looser, her ass more accommodating, her appetite for size endless. She still fucked Mark, still kissed him, still said she loved him. But every time Tyler’s knock sounded on the door, her eyes lit up with pure, filthy hunger. Mark would open it, step aside, and watch his girlfriend drop to her knees for the bigger cock that had claimed her, knowing with absolute certainty that this was their life now.

And every time that massive shaft sank into her, every time she screamed and came and begged for more, every time Mark licked the thick loads from her used holes, he felt the same twisted, humiliating rush that had started that first afternoon—and he never once wanted it to stop.

Lisa’s phone buzzed on the nightstand one rainy Thursday. She was straddling Mark’s face, grinding her freshly fucked, still-leaking pussy against his tongue while he cleaned the afternoon’s creampie. She glanced at the screen, smiled, and held it down so he could see.

A photo of Tyler’s cock, hard and veined, with the caption: Be ready in twenty. Bringing the belt this time. You’re getting fucked until you cry, and your little boyfriend is going to hold you open for every stroke.

Lisa’s hips rolled harder against Mark’s mouth. “You heard him, baby. Get me nice and clean. Then go wait by the door. When he comes in, you’re going to thank him for coming over to fuck your slut girlfriend again. And when he puts that belt around my neck and rails me, you’re going to stroke that little cock and watch every second. Clear?”

Mark’s answer was muffled against her dripping cunt, but the way his tongue worked harder said everything.

Twenty minutes later the door opened. Tyler stepped in, belt already in hand, that monster cock already tenting his shorts. Lisa was on her knees in the middle of the living room, naked, ass up, face down, presenting. Mark stood to the side, cock in hand, heart racing.

“Thank you for coming,” he said, voice rough. “Thank you for fucking my girlfriend.”

Tyler grinned, dropped his shorts, and the heavy cock swung free. Lisa crawled forward and licked a long stripe up the underside, moaning at the taste.

“Good cuck,” Tyler said. “Now shut up and watch me ruin her.”

He looped the belt around Lisa’s neck, tightened it just enough, and slammed into her waiting cunt in one brutal stroke. The wet slap of skin on skin filled the apartment. Lisa’s eyes rolled back. Mark stroked faster, watching the thick shaft disappear and reappear, shiny with her juices, watching the way her body submitted completely to the bigger cock that owned it.

The rain hammered the windows. Inside, the only sounds were Lisa’s choked moans, the wet impact of Tyler’s hips, and the soft, desperate stroke of Mark’s hand on his own inadequate cock as he watched his girlfriend get taken—again, and again, and again—by the bigger cock that had claimed her forever.
