My sister was posing in front of the mirror again, trying on her new short skirts and tank tops for the summer. She loved teasing me and knowing she gets me hard easily. She was getting really frustrated about still being a virgin at 18.
She lifted up her skirt and twirled around, revealing her thong for a moment. “Do you like it, bro?” she asked, playfully?
“I’ll show you how much I like it.” I walked over to her and grabbed her by the throat. “You think you can keep teasing without any consequences, sis?”
I could see fear in her eyes and I smacked her cheek, turning it red. I put a hand on her ass, reaching under her skirt and grabbed it. “I’m gonna fuck that sweet little ass of yours now, you slut.”
I pushed her down to the floor, pulled down her skirt and only moved her thong enough for my cock to be able to reach her teen holes. I dragged it across her wet pussy. She was clearly loving it how her big brother’s about to fuck her for the first time. I placed it on her asshole and pushed in while she let out a scream, all the while knowing this is exactly what she wanted. I made her look at herself in the mirror, to see how my cock is going in and out of her tight virgin asshole as she was moaning.
“See what happens to teasing young whores?” I asked. She was almost in a trance from getting fucked for the first time and all she could do was nod.
