Stepbrother’s Total Defeat By My Revenge Seduction

I’ve always been the one who gets overlooked in our crowded house. My stepbrother, Mark, thinks he’s God’s gift just because he’s got a few years on me and a gym membership. He spends all his time flexing in the hallway mirror, talking over me at dinner, and acting like my every move is an annoyance. Tonight, I decided to turn his smug little world upside down.

He was in his usual spot, lounging on the couch with a controller in his hand, shouting at some video game. I changed into a tiny silk chemise that I knew hugged every curve, and I didn’t bother with shorts. I just walked into the living room, pretending to look for a phone charger. The moment he saw me, his game was forgotten. I could see the shift in his eyes—the realization that the "annoying little stepsister" wasn't so little anymore.

I didn't say much. I just leaned over his lap to grab the charger from the floor, making sure he got a generous view of what I was offering. He was hard within seconds, his jeans straining as he tried to hide it. That’s when I decided to have a little fun. I challenged his ego, telling him he couldn't handle me. He took the bait, pulling me down onto his lap. What followed was a raw, desperate collision of pent-up tension and forbidden curiosity. He tried to dominate, but I was in control. I rode him until he was breathless, his hands gripping my hips like he was drowning. When he finally spilled inside me with a guttural groan, I didn't stop. I kept going until he was begging for mercy, hard again and throbbing. I made that arrogant stepbrother of mine cum twice in one night, completely owned by the girl he used to ignore. The power—and the taboo thrill—was the sweetest victory I’ve ever tasted.
