One night when my sister's friend was there I was in bed and was hard as a rock. I wanted her to see my dick so I got on top of the covers in my under...ear and tried my best to get her to look. I realized that just laying there she would never stop to see it so I put my hand on it. My fingers were wrapped around my balls and the palm of my hand was on my dick. I started jerking it all around. I had never masturbated before and I didn't even know what that was, I was just trying to make alot of. I hadn't seen Kathy had opened her eyes and was watching me. " You think I'm sexy right Tim? I know I've gained some weight, but I'm still sexy right?" my sister asked me. " Your Beautiful s*s," I told her. " Your my brother, of course your going to say that, but as a man, do you think I'm sexy?"I could feel my warm hard cock growing against my belly now. I put my hands on my sisters waist, pulling her to me. Holding heragainst my body I leaned in a whispered in her ear. " Since the party I. Paul and Kim teamed up and challenged Brad and Jack to a game of eight ball. After several games, Megan came in and hugged Jack."Hi sweetie," Megan said as she kissed Jack on the cheek. "Are you ready to spend three weeks with me?" I sure am Megan," Jack replied.Megan put her mouth to Jack's ear and whispered, "I can't wait to get your cock in my pussy baby. I'm going to fuck you silly every chance we get." Oh you are, are you," Jack whispered back."You bet I am," Megan giggled. "You just wait. The fucking bitch had been a virgin herself all this time. She had let out a muffled scream as I broke her cherry. I felt bad that I had broken her hymen and hurt her but fucking her sure felt good. I didn’t really care one bit about her pleasure. I just thrust it into her as fast and as hard as I could. I was a virgin too but she didn’t need to know that. When I cum in her I realized just how great sex was and swore that I would never jerk off again.When I pulled my cock out Rachael released.
