I'm a 37 year old female and have never been in a long loving relationship. I suppose you could say I am only semi attractive but I do take care of my body. My last boyfriend was a drunk and began beating me at times so I moved to another part of the city. I moved into a very small rear apartment and within the first week realized a man in the next building was peeking into my apartment at night. As he would see my bedroom light come on he would go out into the driveway and come up close to my window. The way the apartment is set up he can only see into the bedroom where the window is low enough. I had been without sex for quite awhile and why I started this I truly don't know. I began to give him a show every night he was out there and when I was sure he was out in the driveway I would get undressed letting him see me nude. It aroused me knowing he was watching me and after awhile I began masturbating with the knowledge he was at my window. A few months went by before I actually met this man, finding out his name is Ben and I also met his girlfriend. They are both in their late 50's and although they don't live together I see them and speak to them often. I estimate he sees me nude 3 or 4 times a week and even though I don't masturbate every time I do very often. I almost always use my vibrator and expose myself to him in every way possible. His girlfriend is a very nice lady so I'm sure she doesn't know anything about this. I have had a boyfriend for the last 7 months and the first few times he stayed over I made sure Ben couldn'see in. Then it I began thinking of how erotic it would be if Ben did see me having sex. I aleways had the bottom of the window open a few inches but now if my boyfriend is here I only have it open about a half inch. I purposely checked it once long ago to make sure Ben could see inside with only a crack of the window open. Then I began leaving lights on when we do have sex and know now Ben has been witness many times over the last half year. I can't believe how this turns me on knowing I am being watched by him. I send my boyfriend into the bedroom telling him I will bring in wine or a beer but my main concern is that Ben is in the driveway. I turn off the kitchen light and peek outside to assure myself he is out there. Before I even reach the bedroom I am aroused just by the fact I know Ben will watch us that night. My boyfriend has told me I am aggressive in bed but the main reason I am is because I know we are being watched. I always give my boyfriend a blow job and he normally performs oral sex on me. It sounds crazy I know but I often suggest my boyfriend have intercouse with me in different positions which he is more than willing to do. I still masturbate several times a week for Ben but am always excited more when I know he is watching me have sex. I even introduced my boyfriend to Ben and his girlfriend and we often see them outside. I had never thought about doing such a thing in my entire life but now I am dissapointed when Ben isn't at my window. Sometimes he asks when I will see my boyfriend and often asks when I will be home from work. I never thought much about it at first but think he asks me so he can be availiable to watch me. My boyfriend is mostly here on weekends so I think Ben avoids seeing his girlfriend when he knows he will be able to watch us. During the week he is almost always in the driveway after I turn on the bedroom light. I don't know where he goes but he is never around on Sundays and Tuesdays but know he is out with his girlfriend either on Friday or Saturday nights but never both nights. We have normal conversations and he is never afraid to ask when I will be home or what night my boyfriend is coming over. I know why he is asking and am glad he does ask. I'm positive he likes watching me naked and maturbating and surely likes seeing me have sex with my boyfriend. As much as he must enjoy it I am absolutely thrilled and aroused out of control when he does watch. I have become so addicted to Ben seeing me naked it has become the most satisfying thing in my life. I know its a kinky thing but it is so stimulating I can't explain how I feel even when I am alone.
