I was about 11 when this happened.
I was sleeping over my friends house, (a girl) when she asked if I wanted to watch some porn, after about half an hour I got really horny and I heard her moaning and groaning so I asked what she was doing, she looked at me like I was a stranger then she asked if I had ever masturbated I said no. Then she told to get up and get undressed, I noticed that my hardon was kinda wet, she giggled and showed me what she was doing, it really turned me on then she asked me to help her. she told me told me to start fingering her, just doing that I nearly came. Then she started stroking, after a while she came, she told me that I should continue on my after seconds I came all over her and it felt great!!
