When I was 15 my mom caught me having sex with our neighbor. He was a married black guy in his 40s whose wife was always away. I started fucking him a few months before she caught us.

We were on his couch and I was facing away from him riding his big dick when she came in. She went ballistic. I jumped off his dick and scrambled for my clothes while she and him screamed at each other. She was screaming at me to go home and calling him names and going crazy on him.

Then I realized what was going on. She had come over to fuck him and found us accidentally. My mom was having an affair on my dad with the same guy I was fucking. I went nuts then screaming at her. It was the worst day of my life. She slapped me and I just sat on the floor crying half naked while she tried to talk to me and he tried to calm us down with his hard on still bouncing around.

My mom got him to get dressed and got me dressed and we talked. He apologized. She was a mess. I was a mess. We went home.

She made me promise not to see him anymore and not to tell my dad. She apologized and said I would understand some day. She promised to stop cheating.

We've never been close since. She pretty much pretends it never happened.
