I found the texts on my brother's phone when he left it charging at my place. My wife, bent over his kitchen counter, taking his cock like a whore while she texted him how much better he fucked her than me. That was it. No more talking. No more family dinners pretending everything was fine.
Revenge had to be dirty, and it had to hit him where it hurt.
I drove straight to my sister's apartment across town. Lena was twenty-eight, single, and always had a thing for me even if she never said it out loud. She opened the door in a tank top and shorts, hair messy from sleep. "What the fuck, Mark? It's late."
I pushed inside and shut the door. "Your brother fucked my wife. I'm going to fuck you."
Her eyes went wide, then narrowed with that same filthy spark I remembered from years ago. "You're serious."
"Dead serious. Clothes off. Now."
She didn't hesitate long. The tank top came over her head, tits spilling free, nipples already hard. Shorts dropped, and she stood there naked, shaved pussy glistening. "You want revenge? Take it. But don't be gentle."
I grabbed her by the hair and bent her over the arm of the couch. My cock was already rock hard when I freed it. I spat on her cunt once and shoved in deep on the first thrust. She was tight and wet, gripping me like she had been waiting for this. "Fuck, yes," she hissed. "Pound me. Make it hurt."
I slammed into her again and again, balls slapping her clit, the sound of skin on skin filling the room. Every thrust was payback. My brother thought he could steal my wife? I was balls-deep in his sister, stretching her cunt wide. Lena pushed back, meeting every stroke. "Harder, you bastard. Fuck your sister's pussy like you mean it."
I reached under and rubbed her clit in rough circles while I drilled her. She came fast, cunt pulsing around my shaft, juices running down my balls. I didn't stop. I flipped her onto her back on the floor, hooked her legs over my shoulders, and drove in even deeper. Her tits bounced with every brutal thrust. "Tell me you want my cum," I growled.
"Fill me up," she moaned. "Pump your sister's cunt full. Let him smell it on me next time he sees us."
I fucked her like that for what felt like hours, switching positions whenever I got close. Doggy on the couch, her riding me on the floor, me pinning her against the wall with her legs wrapped around my waist. Every time she came she screamed my name and begged for more. By the time I finally unloaded, I had her on all fours again, ass up, and I flooded her pussy with thick ropes of cum. It leaked out around my cock as I kept thrusting through the orgasm.
We didn't stop there. She sucked me hard again in the shower, swallowing half my load before I bent her over the sink and fucked her ass for the first time. She took it like she was born for it, pushing back and fingering her own clit until she squirted down her thighs. Later we moved to her bed. I ate her cum-filled pussy while she sucked me, then I mounted her missionary and made her look me in the eyes while I bred her again.
By morning we were both sore and marked. Bite marks on her tits, handprints on her ass, my cum still dripping from her holes. She kissed me at the door before I left. "Next time he calls, I'm telling him exactly what we did. Every filthy detail."
I smiled. "Good. Make sure he knows his sister is my new fucktoy."
Revenge tasted better than I expected. And it was only the beginning.
