Three years ago my girlfriend and I went to see my cousin who lives in another city and we stayed one night at his house.
We spent the day at the beach and drinking alcohol. At night he had his room and we slept in the living room on the sofa bed. We were horny and we started to get hotter and hotter until she got on top of me riding my cock, when I heard the door of my cousin’s room and noticed a presence behind us. He had gone out to smoke at the window that was 2 meters from us where he could see us perfectly.
My girlfriend didn’t see or hear anything, I whispered to her to stop but I didn’t tell her why, so she ignored me and kept riding me, moaning low until she cummed.
The next morning I told him everything and he was embarrassed, I don’t know if my cousin saw us or not but I’m sure he noticed something.
