John slammed the door after the last lawyer left. The divorce was final. Sarah had fucked his best friend for six months, and now half his shit was gone. He poured a whiskey and stared at the wall until the phone rang. It was his sister, Lisa. She was two years younger, always the one who called when shit hit the fan.
"John, you okay? I heard everything. Sarah's a bitch. Come over. I got beer and no one to judge."
He drove to her place without thinking. Lisa opened the door in a tank top and shorts, no bra, nipples pushing the fabric. She hugged him hard, tits smashing against his chest.
"Fuck her," Lisa said.
"She cheated, you lost. Time to get even."
They drank fast. Lisa sat close on the couch, leg touching his. "You know what would really piss her off? If you nailed someone in the family. Someone she hates."
John looked at his sister. Her eyes were dark, mouth wet from the beer. "You serious?"
"Dead serious. Sarah always called me a slut behind my back. Let's make it true." Lisa reached over and grabbed his cock through his jeans. It was already hard. She squeezed. "Yeah, you want it."
She unzipped him, pulled his cock out, and dropped to her knees. No teasing. She sucked him straight down, throat working, spit running down his balls. John grabbed her hair and fucked her mouth. "That's it, take it all, you dirty bitch."
Lisa pulled off, strings of spit connecting her lips to his cock. "Bedroom. Now."
They stripped fast. Lisa's tits were bigger than Sarah's, nipples dark and stiff. She spread on the bed, legs wide, pussy shaved and already glistening. "Eat me first. Make me come on your face."
John buried his tongue in her cunt, licking hard, sucking her clit. Lisa grabbed his head and ground against him. "Fuck yes, right there. Suck it." She came loud, thighs clamping his head, juices flooding his mouth.
He flipped her over, yanked her hips up, and slammed his cock into her pussy in one thrust. She was tight and hot. He fucked her rough, slapping her ass red. "This is for Sarah, you cheating whore. Your sister's taking my dick now."
Lisa pushed back, meeting every thrust. "Harder. Wreck me. Tell me how you're gonna fill your sister's cunt."
He pounded her until she screamed another orgasm, then pulled out and shoved into her ass without warning. Lisa yelped but pushed back. "Yes, fuck my ass. Revenge fuck your sister."
John railed her ass deep and fast until he unloaded, pumping cum into her. They collapsed, breathing hard. Then Lisa rolled over and sucked him clean. "Round two. I want it in my pussy again while I call Sarah's name."
They fucked all night. Lisa rode him, tits bouncing, dirty talk nonstop. "Sarah lost the best cock. Now it's mine. Come in me again." John did, multiple times, filling both holes until cum leaked down her thighs.
By morning they were sore and sticky. Lisa kissed him hard. "Divorce papers are signed. This is just the start. Sarah finds out, she's gonna lose her mind. We keep going until she begs."
John smiled, already hard again. Revenge tasted like his sister's pussy, and he was not stopping.
