Mike slammed the door behind him after seeing the video on his phone. His wife Lisa was on all fours in their bed, taking some asshole's cock deep in her pussy while moaning like a whore. The timestamp showed it happened yesterday while he was at work. He didn't scream or cry. He drove straight to his sister Jessica's apartment, the one person who always understood his dark side.
Jessica opened the door in a tight tank top and shorts, her tits straining the fabric. "Mike? What's wrong?" she asked. He pushed inside, locked the door, and showed her the video without a word. Her eyes widened then narrowed. "That cheating bitch. What are you gonna do?"
"I'm gonna fuck you," Mike said, already pulling off his shirt. "Hard. And you're gonna let me because we both know this family shit turns us on." Jessica didn't hesitate. She yanked her tank top over her head, her big tits bouncing free, nipples hard. "Do it. Revenge fuck your sister. Make it dirty."
Mike shoved her against the wall and grabbed her tits, squeezing hard. "You've always had the better body than Lisa. Tighter pussy too, from what I remember." He yanked her shorts down, finding her already wet. Two fingers slammed into her cunt, pumping fast. Jessica gasped and spread her legs. "Finger fuck me, brother. Get that revenge cock ready."
He dropped his pants, his thick dick springing out. Jessica dropped to her knees and sucked it straight down her throat, gagging loud and sloppy. Spit ran down her chin as she bobbed, eyes watering. "That's it, suck your brother's dick," Mike growled, holding her head and thrusting. "Lisa never took it this deep."
Jessica pulled off, strings of spit connecting her lips to his cock. "Fuck me now. Pound my pussy and think about that slut wife." She bent over the couch, ass up. Mike lined up and drove in balls deep in one thrust. Her cunt gripped him tight, hot and slick. He fucked her raw, hips slapping, balls hitting her clit with every stroke.
"Harder, Mike! Wreck this incest pussy!" Jessica yelled. He grabbed her hips and pounded, the sound of wet skin on skin filling the room. Her juices coated his shaft. He reached around and rubbed her clit fast. Jessica came screaming, her walls clenching, but Mike didn't stop. He flipped her onto her back on the floor, hooked her legs over his shoulders, and drilled deeper.
"Tell me how much better my cock feels than that cheater's," he demanded. "Better! So much fucking better! Fill your sister's cunt with cum!" Jessica begged. Mike slammed in one last time and unloaded, thick ropes of hot cum pumping into her. He kept thrusting through it, pushing his load deeper.
They didn't rest long. Jessica climbed on top, sliding his still-hard cock back inside her cum-filled pussy. She rode him dirty, grinding and bouncing, tits swinging. "Revenge sex feels so good," she moaned.

"Imagine Lisa walking in and seeing her husband balls deep in his own sister." Mike thrust up to meet her, hands mauling her ass. "Next time we fuck her sister too. Make it a real family payback."
Jessica came again, squirting around his cock. Mike pulled out, flipped her, and shoved back into her ass this time, stretching her tight hole. She screamed in pleasure-pain as he fucked her ass raw, reaching under to finger her cum-dripping pussy. "Take it all, sis. This is what cheating wives get their husbands to do."
He came again, shooting deep in her ass. They lay there panting, covered in sweat and cum. Jessica grinned. "Send her the video of us. Let her know revenge tastes like incest." Mike grabbed his phone and started recording another round, this time with Jessica sucking his cock clean while looking straight at the camera.
By morning they had fucked in every room, every position, filling every hole. Mike sent the footage to Lisa with one text: "Your move, whore. I'm busy with family now." Jessica laughed and straddled him again for round five, her pussy still leaking his cum. The cheating had started a fire, and the revenge was just getting filthier.
