We had seen each other naked awhile back after swimming, and we had both checked each other out. In fact we had showered in front of each other. It wa... a strange and erotic experience. We both got erections as we watched each other shower. I smiled at him as I slowly "washed" my hard, teenage cock in my soap-covered hands. He looked at it as I did this; his own young cock hard and bit larger than mine, his pubic hair blonde, mine brown, both of our lean, firm asses pale white in contrast to our. I had crossed the room to get some clean underwear when my sister and her friend came in, sat on the side of my bed and smiled at me as I stood there, naked, with a pair of boxers held between my legs, half hiding my painful erection that stood out a half-foot in front of me."Billy," my grinning sister said, "what have you been doing?" The voluptuous blonde giggled."None of your business," I said, turning my back to them and pulling on my shorts. I wiggled my cock straight up against my belly. With a roll of her eyes she sat down on the couch next to me. "AlrightEmily you need to break out of your old habits! I am supposed to teachyou how to fit in, not let you be the class dork. From now on you canread Seventeen and Marie Claire and I only want you to watch kidschannels and music channels." Kids channels?" I asked. "As in cartoons?" Yes you need to develop a common frame of reference with your new agemates. We can cover some of your oddness with the fact that you weresupposedly home. The man teases you, sliding the head up and down yourslit. Pushing the head in part way and then pulling itback out. Pushing it back in and then pulling it backout. Finally he starts to push it into you. Slowly itslides into. Pushing into you, slowly opening you upand filling you up. You let out a gasp as you wiggleyour hips backward. Enjoying the feeling of beingcompletely filled. The man leans forward and begins to bite up and downyour neck as he begins to thrust in and out of you. Ashiver.
