When I was 18, I was still living at home. My parents converted the attic into a bedroom for me, which I loved because it gave me a clear shot into my neighbor’s bedroom across the alley. She was in her 30s and was very popular with the guys. At least two or three nights a week, I’d see her bedroom light flick on. She was too drunk to worry about her open blinds.
Her friend would crawl on top of her and pump away. He’d flip her over and fuck her from behind. He’d pull his cock out of her and push it into her mouth. He’d go down on her. Her legs up in the air. They would fuck and fuck and fuck. And then he would collapse on top of her.
Of course, I’d jerk off the entire time. I got to the point where I would time it so I would cum at the same time the guy she was fucking would cum.
