This started since I became conscious of my changing body as a pre-teen. My breasts started to grow out slowly, and I just came to know about porn, sex and things as such. So I had this intense urge to show myself to someone, without being recognized. My parents worked and I was usually home alone after school back then. As soon as it was dark outside I used to wear my sexiest attire and strip on the terrace. I roamed on the terrace for hours naked, got the guts because it was dark and less likely to be seen. I'm 19 now and though it has lessened, I still love doing it at times. I go to the terrace and masturbate. I even have sex with my boyfriend in the open terrace. It feels great the possibility to be seen but can't because it's dark. Once my mom went out of station for work and because dad returns really late at night, I called my boy over. We had sex on the terrace and fell asleep naked. Later we got up and he went home before dad returned.
