My parents are away on business trips almost every weekend so I stay at my grandma's house. Since last year I think there are somewhere between 7 to 10 neighborhood boys who have seen me naked and have watched me masturbate. They climb up on the garage roof which is connected to the house and can not only see into the spare room I sleep in but also the bathroom. They are all younger than me but the only one I know is a kid who lives a few houses down from my grandma's house. I know his name is Ryan and have seen him outside but have never talked to him. It started with just him but then he started bringing other kids with him. I don't think any of them are even in high school yet and think most of them are 12 or 13. I'll be 17 in September and have been letting them see me naked now for over a year almost every weekend, mostly on Friday and Saturday nights. A couple times I know there were as many as 4 boys out on the roof watching me. It makes me so horny I just keep doing it and on purpose open the windows and blinds so they can see in real good. They usually come after about 8pm so I just tell my grandma I want to shower and watch tv in my room. I sit in the dark waiting for them to climb up on the roof then I go into the bathroom and start getting undressed. Most of the time there are two or three of them and I am so excited about it I want to masturbate right away. Once I'm naked I let them see me shower and shave my legs but not only that I started shaving my pubic hair about 8 months ago. I don't usually masturbate while in the shower but sometimes I am so hot I do. Most of the time I go back to the bedroom and masturbate on the bed. I think knowing they are watching me is what makes me cum so many times. Except for Ryan I don't know who any of the other boys are and because they come when it is dark outside I don't really know how many different boys have watched me for sure. I live about 15 miles away from my grandma so I don't have to worry about seeing any of them where I live. I really don't want to know who they are and don't want them to know me either. Ryan might have been watching me before I found out he was but when I did notice him on the roof I was excited rather than upset about it. I never did anything like this before but all I know is that by them seeing me naked it makes me so aroused I can't control myself. I used to complain to my parents about having to stay at my grandma's asking them to stay home alone. Ever since I began letting the boys see me naked I don't complain anymore and am dissapointed when my parents stay home some weekends. I use to hate it when they went away but now look forward to it. I can't believe what I let these boys see me do and there where times I even changed tampons knowing they were at the window. When I masturbate on the bed I purposely have my legs wide open facing the windows. I even get on my hands and knees spreading my legs with my butt facing the windows. I do things in front of them I never considered before and intentionally walk right up to the windows naked. I even play with myself standing up sometimes and also play with my breasts. I know I should feel shame or remorse about doing this but it excites me so much I don't have any regrets about it. At home I never do anything like that but do masturbate often. I have dated a few boys but have never had sex with any of them. I did let one of them feel me up once but even none of them ever saw me naked. I'm not sure why but having those boys see me nude most weekends has made me very happy and more aware of my sexual feelings. I've been masturbating for a few years now and think I was still 12 when I started. With the boys watching me it is much different because I orgasm a lot more than when I am alone. Just knowing they are on the roof I keep masturbating after I cum the first time and just continue to have orgasms. I don't really know but those boys are old enough to masturbate themselves. I can't see them but am pretty sure they get erections when they watch me or at least I hope they do. I never let on that I know they are out there and hope they think I don't know they are. I never look directly at the windows but many times have been able to see some faces, even though I still don't know how many boys have watched me.
