I let the woman in the apartment across from me, watch me undress and shower. I live in a apartment complex that has two buildings face each other in a "V" shape. My apartment sits right on where the two halves of the "V" meet. My bedroom and bathroom window also face out, pointing at the opposite apartment from me. I know that there a female that lives in the unit that live alone. She is a nice girl, as I have met her before in the mailroom and in the elevator. Normal girl, bit pudgy, but not unattractive. Anyway, about 8-9 months ago, I was getting ready for work in the morning, and in the reflection of the mirror in my bedroom, I could see her in her apartment looking at me. I usually get ready in my closet, so I was not naked at the time, I was just putting on my tie. I came home early one day and looked out my windows, I was very clear that I could see into her apartment from my bedroom and from my bathroom. The blinds are usually drawn, so I do not think she could see me. That night, for kicks I guess, I left the blinds wide open. I saw her apartment light go on, and I went in the bedroom to change my clothes. I immediately saw her light go out in her unit, so I had a feeling that she was watching me. I removed my clothing, and then walked around my bedroom in only my underwear. I did this for about 10 minutes. I then saw what looked like a cellphone display click on, then went dark right away....so I knew she was there...watching me. I felt bold, I then removed my underwear, and walked around my room nude. I then went into my bathroom and took a shower. My shower is full length clear glass door. I masturbated in the shower thinking about her looking at me. I went back to my room after the shower, and put on a pair of boxers and lounged on the bed. I kinda peeked my penis out the side of the boxer leg. I got up a few minutes later and drew the blinds closed. A few minutes later, the lights went on in her apartment again. I have been doing this for the last 8 mths or so for her. I will walk around nude or in my underwear. I will shower with the blinds open or the window open. I will masturbate in full view. I am always putting on some kind of show for her. There have been a few times, I have seen her in her apartment in something skimpy or something loose. I saw her naked once or twice. Never saw her in the shower yet, but I know I can see into her bathroom.
