Jack was asleep. Soundly. His breathing was slightly laboured but he wasn't quite snoring. The curtains were open and the moon made the inside of his ...room pale and silvery. Jack was sleeping under one sheet only as it was a hot night and his mother, still horny from the fingering she had just come from with his sister noticed a slight tenting in that one sheet.Jack was a lovely kid. He was fifteen but in some ways much less mature than his little sister. He stood just under 5'9'' which seemed. The situation was turning me on something fierce.Her white panties were snug enough against her firm womanly butt that they clearly showed her tiny crack outlined in a groove in the thin cotton.Soon enough my cock started to get hard. I considered leaving to my room to get some relief, but the mere idea started deflating my hard-on.Since I was behind her, and knew she couldn't see me I began to rub my hard-on through my robe while watching this girl's hot ass. I tried to be as inconspicuous as. She was avirgin when we met and said that she would stay a virginuntil she got married. Robin was very conservative andmodest. She had a good figure but always covered it up withbaggy sweaters and loose fitting clothing.Dan would ask me all the time when I was going to fuck her.I told him that she wasn’t that kind of girl. But Dan saidthat all girls were ‘that kind of girl’ if they foundthemselves in the right situation. He told me to hurry upand fuck her or he would have to. When we got to my fiancé’s house he literally had to carry me up the steps and put me into bed. I laid there for hours watching the ceiling fan…which while off seemed to me to be self-propelled. Every time I closed my eyes the room spun. The next morning finally arrived and I got up and drank enough water to take some Tylenol…two minutes later I was puking again…the toilet went completely pink with white zinfandel…after 6 hours and all the throwing up I’d already done. I finally got some food.
