I walked in on my wife, Karen, on her knees in our living room, her mouth stretched around our neighbor Mike's thick cock while his wife Lisa filmed it on her phone. Karen's tits bounced as she gagged and slurped, spit running down her chin, and she moaned like a total slut when Mike shot his load down her throat. They didn't even notice me at first. I stood there, dick already hard from the shock and rage, watching my wife cheat right in our house.
Karen finally saw me and froze, cum dripping from her lips. "Baby, it's not what it looks like," she started, but I just laughed. "Shut the fuck up. You want to play games? Fine. Tonight you're going to watch me fuck your sister."
I called up Karen's sister, Jenna, who had always been a horny bitch around me. Jenna showed up twenty minutes later in a tiny dress, no panties, already wet when I told her the plan. "Revenge on my cheating sister? Fuck yes," she said, dropping to her knees and yanking my cock out.
She sucked me deep and sloppy, tongue swirling, while Karen sat on the couch forced to watch. Lisa and Mike stayed too, touching each other, getting off on the mess.
Jenna bent over the arm of the couch, ass up, and I slammed into her tight cunt from behind. "That's it, fuck your wife's sister," she groaned, pushing back hard. Karen's face burned red but her nipples were stiff under her shirt. I pounded Jenna's pussy, balls slapping, telling Karen every detail. "Her cunt's so much tighter than yours, you dirty whore." Jenna came first, screaming and squirting on my cock, then I pulled out and painted her ass with thick ropes of cum.
Mike couldn't take it anymore. He pulled Lisa onto the floor and started fucking her while staring at Jenna's dripping body. "We cheat too," Lisa admitted between moans. "Mike's been railing my sister for months." That lit the fuse. Jenna crawled over and started licking Lisa's clit while Mike fucked her, and Karen finally broke, sliding her hand into her own panties.
I grabbed Karen by the hair and shoved my cock in her face. "Clean it off, slut. Taste your sister's pussy on me." She sucked greedily, eyes watering, while I watched the two couples tangle on the floor. Jenna climbed onto Mike's face and ground her wet slit on his tongue. Lisa straddled me next, sinking down on my dick with a filthy moan. "Fuck me while your wife watches," she begged. I thrust up hard, pounding her cunt, and Karen fingered herself faster, humiliated and turned on.
The night turned into a full swap. Jenna and Karen ended up side by side on the couch, asses up, while Mike and I took turns fucking both sisters. I buried my cock in Karen's pussy then pulled out and drove straight into Jenna's, making them both beg. Lisa sat on Karen's face and rode her tongue, calling her a cheating cumdump. Cum flew everywhere: on tits, in mouths, leaking down thighs. Mike filled Jenna's cunt while I unloaded in Karen's ass, then we made the sisters lick each other clean.
By morning we were all wrecked and satisfied. Karen looked at me with cum-streaked cheeks and said, "We're even now, but I want to do it again." The cheating couples had become one filthy revenge family. We still swap every weekend, sisters and all, raw and nasty, no limits left.
