Well this is very strange I thought, browsing through the options, it seemed I could alter just about anything about me, although I didn't understand ...hy I was there, let alone my family as well. The first menu indicated physical appearance, I thought sod it and went to the slider menu that said 'cock size', like most men I wanted bigger and fatter so I dragged the slider to the right as the picture increased my cock size. To my shock, I felt something moving down my leg, I looked down and. I'd gone to my room and settled down to do the reading and writing I needed to get done, when there was a slight knock at my door and my sister Jane stuck her head in to see what I was doing and then she came on in and plopped herself down on the end of my bed. Jane and I were very close as a brother and sister and she'd often come and bare her soul with me when she was having boyfriend or Dad problems -- or even problems at school with a teacher or with one of her classes. I didn't mind her. My heart fluttered when i heard it.I looked around and said "Nice place" I turned around to look at him and he was already opening his pants.I kicked my shoes off and paused of a second as he finished removing his pants and boxers.All i could do was stare at his cock that was slowly rising. I looked at him and said " You're going to like this" and pulled my shirt off to show part of what i was wearing. he said"I like it so far" with a smile. I opened my jeans and slowly pulled them down. After that, she asked if I wanted to feel the best possible and I nodded. Immediately she went for a deep throat. She said if I feel like cumming I should tell her.When ever I told her she would stop for a minute, but I very badly wanted to cum. So I didn’t tell her and burst all my load in her face and mouth. She got angry and said now who will fuck me. I said I am ready for next round too. Seeing my dick still hard she was happy.Then, we were in missionary position. I slowly entered her, god.
