I caught my wife fucking my brother in our bed. Plain as day. Her legs spread wide, his cock slamming into her sloppy cunt while she moaned like a whore. She was three months pregnant, belly just starting to show, and the baby sure as hell wasn't mine. I'd had a vasectomy years ago. The cheating bitch had been riding his dick raw for months.
I didn't say a word that night. I waited. Revenge came easy once I decided who to use. My sister, Lisa. She was 28, single, and had always given me those long looks at family barbecues. Tight body, big tits, and a mouth that looked made for sucking cock. She lived two towns over. I drove there the next day and told her everything.
Lisa listened, eyes wide, then smirked. "So you want to get even by knocking me up? That's fucking twisted, big brother." But her nipples were hard under her tank top and she was already rubbing her thighs together.
I didn't waste time. I grabbed her, shoved her against the kitchen counter, and yanked her shorts down. Her pussy was shaved and dripping. I spat on my fingers, shoved two inside her, and worked them hard until she was panting. "You want this revenge fuck as bad as I do," I growled.
She dropped to her knees right there on the tile and pulled my cock out. Her mouth was hot and wet, tongue swirling around the head while she took me deep. Sloppy sucks, spit running down my balls. I fucked her face until tears streaked her makeup, then hauled her up and bent her over the counter.
I slammed into her from behind in one thrust. Her cunt gripped me tight, slick and greedy. I pounded her hard, skin slapping loud, telling her how my wife had begged for my brother's load while carrying his kid. Lisa moaned louder, pushing back, begging me to fill her up the same way. "Breed me, brother. Make me pregnant so she sees what real revenge looks like."
I flipped her around, lifted her onto the counter, and drove back in. Her tits bounced with every thrust. I sucked hard on her nipples, biting just enough to make her yelp and clench around me. She came first, pussy pulsing, juices coating my shaft. I kept going, chasing my own release, then buried deep and unloaded. Thick ropes of cum pumped straight into her womb. I stayed inside her, grinding, making sure every drop stayed put.
We didn't stop there. Lisa pulled me to her bedroom. We fucked all afternoon. Doggy style on the floor, her riding me reverse cowgirl while I slapped her ass red, then missionary with her legs over my shoulders so I could watch my cock stretch her. Every time I came, I told her to take it all, to get pregnant so my wife would see the swollen belly and know exactly who had done it.
By the time I left, Lisa had my cum leaking down her thighs and a wicked smile. "Call me when you want round two. Or three."
Two months later Lisa texted a positive pregnancy test. I showed it to my wife during dinner. Her face went white. "You did what?" she whispered.
I leaned back, calm as anything. "Fucked my sister. Got her pregnant. Same way you let my brother knock you up. Difference is, I'm not hiding it."
She tried to scream, to cry, to threaten. I just laughed. Lisa moved in with me the next week. We kept fucking raw every night, her belly growing while my wife's shrank after the miscarriage she had from the stress.
My sister moaned louder than my wife ever had, especially when I took her from behind and told her she was the better fuck, the tighter cunt, the one carrying my kid.
Revenge tasted sweet. Every time I pumped another load into Lisa's pregnant pussy, I thought about my cheating wife listening from the guest room down the hall. She could hear every slap, every grunt, every time Lisa begged her big brother to breed her again. And she knew she had started it all.
