I cucked my ex’s younger brother. He was always super forward and overly sexual with his older sister, my ex. She’s an absolute stunner. Brunette, blue eyes, perfect body and the most amazing ass on the planet. So I get it, he’s young and dumb and full of cum. His sister is smoking hot and kind of a slut.
But he was too forward. Smacking her ass. Trying to wrestle with her. I caught him stealing her dirty panties numerous times when we were visiting. She never took any of it seriously and played it off, pretending like it didn’t mean anything. Now I know she secretly enjoyed it. But it was pissing me off. I was getting close to a breaking point.
We go to visit one weekend and it’s early in the morning. Me and the ex had both just taken a shower and are in our room drying off. I can’t fucking resist this girl naked, so as she tries to slip on a tiny little thong I grab her up and she wraps her legs around my waist. I’m a big guy, 6 foot and 210 pounds. I’m a Marine veteran and in better shape than most. She’s tiny besides that incredible ass. So I’m just holding her there, cock throbbing against the underside of her ass, one arm around her waist and the other rubbing from her tight ass to her dripping pussy.
