Sarah showed up to the party in a tight white dress that hugged her ass and barely covered her tits. The black and white theme meant everything was stark, and she stood out like a slut waiting to be claimed. Her husband Mike had already wandered off with his buddies, leaving her alone with a drink in her hand. She felt the eyes on her right away, especially the tall black guy in the corner who kept staring at her curves.
His name was Marcus. He walked over without asking, leaned in close, and said, "You look like you need a real man to fuck that married pussy tonight." Sarah's face flushed but her nipples hardened under the thin fabric. She didn't walk away. Instead she let him pull her toward the back hallway where the music was louder and the lights dimmer.
Marcus didn't waste time. He pushed her against the wall, yanked her dress up over her hips, and shoved two thick fingers straight into her cunt. "Already wet for black cock, huh?" he growled. Sarah moaned and spread her legs wider. She could hear party guests laughing just around the corner, but that only made her hotter. Marcus pulled his fingers out, unzipped, and slapped his heavy black dick against her bare pussy lips. It was massive, veined, and already leaking. He rubbed the head up and down her slit, teasing her clit until she begged.
"Fuck me," she whispered. "My husband never fucks me like this."
Marcus slammed inside in one hard thrust. Sarah cried out, her back arching as he stretched her wide.

He fucked her rough and fast, pounding her married hole while his balls slapped her ass. People could have walked by at any second. She didn't care. Her pussy clenched around him, creaming on that thick black shaft. Marcus grabbed her hair, pulled her head back, and told her she was a cheating white slut who needed real dick. Every word made her drip more.
He spun her around, bent her over a table, and drove back in from behind. Sarah's tits spilled out of her dress as he railed her. She came hard, legs shaking, juices running down her thighs. Marcus kept going, using her like a fucktoy until he flooded her cunt with thick ropes of cum. He pulled out and let the rest drip down her legs onto the floor.
Sarah barely had time to fix her dress before another guy appeared. This one was white, but he had watched the whole thing from the shadows. He stepped up, cock already out, and said, "My turn on the cheating wife." Sarah dropped to her knees right there and sucked him while Marcus's cum still leaked from her pussy. The white guy fucked her mouth deep, making her gag, then bent her over the same table and slid into her sloppy hole. He pounded her while calling her a filthy party whore. Sarah pushed back against him, loving every second.
They moved to a quieter room later. Marcus returned with a friend, another black guy even bigger than him. The two of them took turns on her while the white guy watched and stroked. Sarah was on all fours, one black cock in her mouth and another stretching her pussy. They switched, double-teaming her until she was a moaning, cum-filled mess. Her white dress was stained and torn. Her husband was still somewhere at the party, clueless.
By the end of the night Sarah had been fucked in three different rooms. Cum leaked from her pussy and ass. Her makeup was smeared. She walked back to Mike with a satisfied smile, feeling the sticky mess between her legs. He asked if she'd had fun. She said yes, already planning the next black and white party where she'd cheat again.
