She knew it was wrong the second she unlocked the door for Mike, but her pussy was already throbbing and wet from the dirty texts they'd swapped all day. Her boyfriend was two states away on a work trip, sending her sweet goodnight messages while she stood in their apartment wearing nothing but a thin tank top and no panties. Mike stepped inside, eyes locked on her hard nipples, and she didn't waste time with small talk. "Fuck me hard," she said, grabbing his belt. "Right now."
He shoved her against the wall and yanked the tank top up, sucking one nipple into his mouth while his hand slid between her legs. Her cunt was dripping, slick coating his fingers as he rubbed her clit in fast circles. "You're such a cheating slut," he growled, pushing two fingers inside her. She moaned loud, grinding down on his hand. "Yes, I'm his cheating girl. Now shut up and fuck me."
They didn't make it to the bedroom.

He bent her over the kitchen counter, kicked her legs apart, and freed his thick cock. She reached back and spread her ass cheeks, showing him her soaked hole. He slammed in deep on the first thrust, stretching her pussy wide. She cried out, gripping the counter edge as he pounded her, balls slapping against her clit with every rough stroke. "Harder," she begged. "Make me forget his name."
Mike grabbed her hips and fucked her like he owned her, the wet sounds of his cock driving into her cunt filling the kitchen. Her tits bounced against the cool countertop. She came fast, pussy clenching and squirting a little around his shaft, but he didn't stop. He pulled out, spun her around, and lifted her onto the counter so he could shove back in face to face. Her legs wrapped around him while he hammered her, thumb pressing hard on her swollen clit until she came again, screaming and digging her nails into his back.
They moved to the couch next. She got on all fours, ass up, and he slid into her from behind again, deeper this time. He spat on her asshole and rubbed it with his thumb while he fucked her pussy raw. "You love cheating on him with my cock, don't you?" he said. She pushed back, taking every inch. "Yes, fuck, I love it. His dick never feels this good." He reached under and pinched her nipples, twisting just enough to make her whimper, then flipped her onto her back and folded her legs to her chest so he could drill straight down into her.
Her third orgasm hit when he started talking dirtier, telling her exactly how many times he'd jerked off thinking about ruining her for her boyfriend. She came so hard her vision blurred, cunt pulsing and milking him. Mike pulled out at the last second and stroked his cock over her tits, shooting thick ropes of cum across her chest and neck. She rubbed it into her skin, licking her fingers clean while he watched.
They weren't done. She sucked him hard again on the living room floor, taking his cock down her throat until drool ran down her chin. Then she climbed on top and rode him reverse cowgirl, bouncing on that fat dick while he slapped her ass red. Every time she thought about her boyfriend's name lighting up her phone, she slammed down harder, chasing another orgasm. Mike filled her pussy this time, pumping load after load deep inside her while she ground her clit against his base and came with him.
Later, lying there sweaty and leaking his cum, she texted her boyfriend back with a smiley face and "miss you too." Mike was already getting dressed, but she knew he'd be back the next night. Her pussy ached in the best way, sore and used, and she couldn't wait to cheat again.
