College Girl Fucks Her Brother-in-Law’s Massive Cock-Incest Story by Salty Vixen

Madison had hated Jake from the minute her sister Lauren brought him home.

He was thirty-one, broad as a doorframe, the kind of former college safety who still moved like the game hadn’t ended. Dark hair, a mouth that defaulted to smirk, and the unforgivable habit of calling Madison “kid” even after she’d turned twenty. She called him a meathead. He called her a spoiled campus princess. They were arch enemies in the most suburban way possible: Christmas dinners with clenched jaws, group chats they both muted, and a shared talent for finding the worst possible thing to say in front of family.

Then State won the Saturday night game in overtime, and Lauren decided the only correct response was a post-football party at their house.

The place filled with jerseys, beer, wings, and the kind of yelling that made the sliding glass door rattle. Madison showed up in a State crop hoodie and a bra that was doing more work than the hoodie wanted to admit—black, thin straps, the kind that made the neckline look accidental. Jake noticed. Of course he noticed. He was leaning on the kitchen island in a faded number-24 shirt, massive forearms crossed, watching her like she’d walked into his locker room by mistake.

“Didn’t think the princess did football,” he said.

“Didn’t think the benchwarmer still pretended he mattered,” she shot back.

Lauren groaned from the fridge. “Can you two not for one night? Poker after this. Be adults.”

Poker happened in the dining room once the crowd thinned to eight people who could still count cards. Madison sat across from Jake. The overhead light made the green felt look cheap and serious at the same time. Buy-in was twenty. Dares crept in after the second round because someone—Jake—said regular poker was for cowards.

Madison lost a hand on purpose the third time just to see what he’d do.

“Bra,” he said, lazy, like he’d been waiting. “On the table. Hoodie stays if you want to be shy.”

Lauren had gone outside to smoke with two of her friends. The remaining guys hooted like idiots. Madison stared at Jake, peeled the hoodie off, and unhooked the black bra with one hand. She dropped it on the pot. Her tits sat full and high, nipples already tight from air and adrenaline. Jake’s eyes dropped and stayed there a second too long.

She won the next hand.

“Shirt,” she said. “And stop looking at me like you just discovered women.”

Jake pulled the jersey over his head. Chest like he’d never left the weight room. A line of hair disappearing into his jeans. Madison hated that her mouth went dry.

The party bled out after midnight. Lauren crashed upstairs with a headache and a “don’t burn the house down.” Two stragglers called rides. That left Madison in the downstairs hallway looking for her hoodie and Jake’s laugh from the half-bath near the den.

She shouldn’t have opened the door.

She did.

Jake was sitting on the closed toilet lid, jeans shoved to his thighs, fist wrapped around a cock that was not a normal-person cock. Massive. Thick enough that his fingers didn’t meet. The head was dark, shiny, a slow stroke from base to tip like he’d been at it long enough to get mean with it. His head was tipped back. He hadn’t locked the door.

Madison’s breath snagged.

He opened his eyes.

For one raw second neither of them performed the arch-enemy script. Then his jaw tightened and he didn’t even bother covering up.

“You lost the ability to knock, princess?”

“You lost the ability to jerk off somewhere that isn’t my sister’s house?”

His hand was still on it. It twitched. A bead of precome welled and slid.

Madison stepped in and shut the door behind her. The small room smelled like soap and heat. Her bra was still on the poker table. She was standing there in a crop hoodie she’d thrown back on without it, tits loose underneath, staring at the thing he’d been hiding under all that hostility.

“Caught you,” she said.

“Yeah.” His voice had gone low. “You going to run and tell Lauren, or you going to stand there and watch like you’ve been dying to?”

She should have left. She locked the door instead.

“Poker wasn’t finished,” she said. “Handjob. That’s the pot I’m collecting.”

Jake let out a short, incredulous breath. “You hate me.”

“I do.” She dropped to her knees on the bath mat anyway. “Doesn’t mean I’m leaving that alone.”

Up close it was worse. Heavier. The vein along the top stood out when she wrapped both hands around him and still had shaft left. Jake’s abs flexed. Madison stroked once, tight, watching his mouth fall open against his will.

“Fuck—”

“Don’t talk,” she said. “You talk like an asshole. Just sit there.”

She spit on the head and worked him with both hands, twisting on the upstroke the way she’d learned from worse ideas than this one. His cock was so thick her thumbs rubbed together over the slit. Precome slicked her fingers. Jake’s hand landed in her hair—not gentle, not cruel, just holding on like the rivalry had finally found a use.

She leaned in and licked the underside, base to head, then took as much as she could. Her lips stretched. She gagged, pulled off, stroked the spit down, and went again. The bathroom fan hummed. Down the hall a replay of the game was still talking about the overtime catch.

Jake’s thigh jumped under her palm.

“Madison. I’m gonna—”

She pulled off and finished him with her fist, fast and mean, aiming up. He came hard across her chest, the hoodie, the underside of her bare tits where the fabric had ridden. Thick ropes. He cursed through his teeth like it physically offended him how good it was.

Madison sat back on her heels, looked down at the mess, and laughed once, sharp.

“Still enemies,” she said.

Jake was breathing like he’d run a sprint. “Yeah.” He reached out, thumbed come off the curve of her breast, and—because he was exactly the kind of man she hated—put his thumb in her mouth. She sucked it clean before she could decide not to.

That should have been the end.

It wasn’t.

They ended up in the den with the TV still on, muted crowd noise, the poker chips abandoned like evidence. Madison stripped the sticky hoodie off and sat on the edge of the couch in nothing but jeans. Jake stood in front of her, jeans still open, that massive cock already thickening again like the first round had only made it rude.

“Truth,” she said, because the party game hadn’t actually died. “How long?”

“Since the wedding,” he said, no joke in it. “You in that dress, looking at me like you wanted me dead. I went home and thought about your mouth. Your turn.”

“Dare,” she said. “Fuck me like you can’t stand me.”

He hooked his fingers in her waistband and yanked her jeans and panties down together. She kicked them off. Jake pushed her back into the couch cushions, hooked her knees over his elbows, and lined that thick head against her. She was wet enough that the first inch slid. The rest made her gasp and grab the couch.

He didn’t ease in. He gave her the stretch in two heavy thrusts until he was seated and her eyes were wet and her mouth was open on a sound she was going to deny later.

“Christ, you’re tight.”

“Don’t compliment me.”

“Wasn’t.” He pulled out and slammed back in. The couch bumped the wall. “This is me winning.”

Madison raked her nails down his back and lifted her hips to take it. He was so thick she felt every drag. The football broadcast flickered blue light across his shoulders, across her tits bouncing with each thrust, across the black bra still sitting on the dining table like a flag.

He fucked her like the game had gone to overtime and he was the late hit. Hard. Deep. One hand braced by her head, the other on her throat just enough to make her look at him. Arch enemies didn’t kiss. They almost did anyway, mouths close, breathing the same air, hate and heat mashed together.

Madison came first, clenching around that massive cock so hard Jake groaned into her neck. He didn’t stop. He kept pounding her through it until she was shaking and swearing and pulling him closer with her heels.

“In me,” she said. “Don’t you dare pull out like a gentleman.”

He laughed, wrecked. “Never been one.”

He buried himself and came inside her in thick pulses that she felt. They stayed locked like that, the house quiet except for the fridge and the distant tick of the sprinkler next door.

Madison shoved at his shoulder after a minute. “Get off. If Lauren comes down—”

“She won’t.” He still pulled out slow, watching his come slip out of her. Possessive in a way that should have started the fight again. It didn’t.

She sat up, sticky, furious, satisfied. “This was a one-time stupid post-game thing.”

Jake tucked himself away like he didn’t believe her. “Sure, princess.”

“I mean it.”

“I know.” He picked her bra up off the table on the way past and tossed it at her chest. “Wear it next time you decide to collect a pot.”

Madison caught it. Her hands were still shaking.

“There isn’t a next time.”

Jake looked at her from the hallway, oversized, smug, still a little wrecked, the overtime win glowing faint on the muted TV behind her.

“Then stop looking at me like you already scheduled it.”

She put the bra back on without answering. The clasp felt louder than the party had been.

Outside, the suburban street was dark and ordinary. Inside, the poker chips were still scattered, the jersey was on the floor, and Madison could still feel the shape of him when she walked to the kitchen for water.

Arch enemies.

One post-football party.

One locked bathroom door.

She drank the water, stared at the dark backyard, and already knew she was going to lose the next hand on purpose.
