My apartment is the first floor rear apartment in a 8 apartment building. I live alone and because the back of the building is only an overgrown lot I never had a privacy problem. Three weeks ago I found out from an upstairs neighbor that her two daughters had been peeking into my bedroom for what must have been several months. The worst part is they not only saw me and my girlfriend naked but saw us having sex and had to see me masturbating several times. Their mother only showed me 4 pictures they took then immediately erased them. She then told me that the girls took at least 50 pictures but she made them erase all of them. These two girls are 13 and 15 and I don't see them often but each time I do I am so mad and embarrassed I am in the prosses of getting out of my lease. My girlfriend is here most weekends and I haven't told her about it yet and think maybe not tell her at all. One of the pictures their mother showed me was of me and my girlfriend in bed naked. The more I think about it I have no clue to how long they had been doing this. I do masturbate often during the week and if those girls took all those pictures I'm sure their mother saw all of them and its humiliating every time I see her or the girls. I have blinds on the windows but evidently they were not totally closed enabling them to see in well enough to take pictures on their phones. I know their mother told me all the pictures are gone now but don't who or how many other people saw them. For all I know those girls could have showed them to friends and other kids in the neighborhood before their mother discovered them. Their mother never mentioned pictures of me masturbating and only told me naked pictures. The four she showed me were one of me and my girlfriend and the other three showing me from the rear or side. If they took those pictures there must have been many more a lot more embarrassing then those.
