I stay the night at my friends house a lot, but this weekend he was out of town, but I stayed the night anyway, so I got to sleep in his bed.
Well in the room there is his bed and also his other sisters aged 15. I think she is pretty cute. Well when everyone else was asleep I took off the covers and pulled down my pants and I just looked over at his sister, I watched her as I jacked off. It was so nice because if anyone woke up or walked in I would have been caught, I really liked it.
When I came it was great.
