Mia had been with her boyfriend for three years when it happened. She never planned on cheating, but one look at that massive cock changed everything. It was at her friend Lisa's house party. Everyone was drunk and loud, music thumping through the backyard. Mia went inside to use the bathroom and the door to the guest room was cracked open. She pushed it wider without thinking and froze.
There was Lisa's cousin, Jake, fresh out of the shower, towel dropped on the floor. His cock hung heavy and thick between his legs, easily twice the size of her boyfriend's. It was veined, the head broad and dark, balls hanging low and full. Mia's mouth went dry. She stared for too long before he noticed her. He didn't cover up right away. Instead he smirked, gave it a casual stroke, and said, "You like what you see?"
She slammed the door and hurried back outside, heart hammering. The image burned in her head for the rest of the night. Every time she looked at her boyfriend she compared him. Small, soft, nothing like that monster she'd seen. She went home and fucked her boyfriend that night but kept picturing Jake's cock. She came harder than she had in months, but it wasn't enough.
Two days later she texted Lisa for Jake's number. Said she needed to return something he'd left at the party. It was a lie. Jake answered on the first ring. They met at a cheap motel off the highway. No small talk. The second the door closed Mia dropped to her knees and yanked his pants down. There it was again, already half hard and growing fast. She wrapped both hands around it and still couldn't cover the whole length. "Fuck, it's huge," she muttered, licking the head.
Jake grabbed her hair and pushed forward. Mia opened wide and took as much as she could. Her jaw ached. Saliva ran down her chin and dripped onto her tits. She gagged when the head hit the back of her throat but kept going, hungry for it. She pulled off only to spit on the shaft and stroke it with both fists. "Bigger than my boyfriend's. Way bigger."
"Shut up and suck," Jake said, thrusting again. Mia moaned around the thick meat, eyes watering. She sucked until her throat was raw, then stood up and stripped. Her pussy was soaked, lips puffy and slick. She climbed onto the bed on all fours and spread her legs. "Fuck me with that big cock. Make me cheat."
Jake didn't need more invitation. He lined up and pushed in. Mia gasped as her cunt stretched around him. It burned in the best way. Inch after inch sank deep until his balls pressed against her ass. She'd never been so full. Her boyfriend couldn't reach half this far. Jake started pounding, hard and fast, the bed slamming against the wall. Mia clawed the sheets and begged for more. "Harder. Wreck my pussy."
He flipped her onto her back, hooked her legs over his shoulders, and drove in even deeper. The head of his cock battered her cervix with every thrust. Mia's tits bounced wildly. She reached down and rubbed her clit, coming hard around the thick shaft. Her walls clenched and pulsed. Jake didn't slow down. He kept fucking through her orgasm, sweat dripping onto her stomach.
They switched positions again. Mia rode him, sinking down until her ass touched his thighs. She ground her hips, feeling every vein drag along her inner walls. "I'm such a slut for this cock," she panted. "Can't go back to my boyfriend after this." Jake grabbed her ass and bounced her harder. Her juices coated his shaft and balls. The wet sounds filled the room.
She came again, legs shaking, pussy squirting a little around his cock. Jake pulled out and flipped her onto her stomach, then mounted her from behind. He slammed back in and fucked her like a machine, grunting with each thrust. Mia buried her face in the pillow and took it, moaning loud enough for the neighbors to hear. When Jake finally came he pulled out and painted her ass and lower back with thick ropes of cum. It felt hot and heavy, marking her.
They lay there catching their breath. Mia's phone buzzed with a text from her boyfriend asking when she'd be home. She ignored it. Instead she reached for Jake's cock again, already starting to swell. "One more round," she said. "I want it in my ass this time."
Jake grinned and rolled her over. Mia spread her cheeks and let him work that massive cock into her tight hole, inch by painful, perfect inch. She came twice more before he filled her ass with another load. By the time she left the motel her legs were weak and her holes were sore and leaking. She knew she'd be back the next day. The story of how she cheated after seeing that big cock was just getting started, and she wanted every filthy chapter.
