I'm a gay man. I have always had the fantasy about watching a man jerking off, and last year that fantasy came true.
During my summer vacations last year, I went to visit my friend Belinda. One day, she was it the back yard giving herself a manicure or something, so I stayed at the living room watching TV, 'cause I wasn't able to go out there, afraid of her dogs. When I was there, I saw her brother, who's around 42 years old, entering into the bathroom to take a shower. The curiosity of watching him naked turned me on. So, I waited and after a little time I heard the sound of the shower. I went to the bathroom door and noticed that there was a little groove between the door and the wall. I was a little scared, but with all my wishes, I decided to spy and saw him stroking his cock, which was really big. I couldn't believe it... His dick was around 9 inches long, and had a lot of black hair on the base. I was fascinated watching his foreskin retracting back and forward as he moved his hand around his shaft. With his free hand, he touched his scrotum very slowly. I was so hot, but couldn't jerk myself there. He started moving his hand faster until he shot his load of cum. Then he started to bathe his body.
That night, on my bed, I masturbated myself remembering the scene. I guess I had two or three orgasms that night. It was great!!!!
Now, every time I go to Belinda's home, I enjoy the moment when her brother takes a shower, 'cause I've discovered that he masturbates almost daily. That vacation, I saw him jerking off almost 6 times a week... and I did my part at night on my bed.
