Mom’s new sex life.

First off let me say that my name is Andy. I’m 15 and pretty heavy into sports so I’m in decent shape. I’m an only child and live with my mom. My mom, Becky, is 37 with fire red hair, good size breats and one of the tightest asses you will ever see. She has a very toned and curvy body. I’ve been having sex with my mom, among others, for about a year and a half now.

This is my story…..

My dad left when I was very young. I hardly remember him at all other than him and mom fighting a lot. It devestated my mom when he left. She used to cry for hours at night. After a couple years she started dating again. Most of the guys were total losers. Then on my 13th birthday she took me out to dinner and said she had a surprise for me. When we got there I saw the new guy she’d been dating. He was pretty cool, he was into sports like me so we got along and he treated my mom well. After dinner my mom said she had something to tell me. They were getting married. I was kinda shocked by I also saw it coming so I wasnt to surprised.

Three months later they were married.

By this time I new all there was to know about sex. I had even had it a few times with a couple girls from school. One night about 10 or 11ish I got up and had to go to the bathroom. To get the the bathroom I have to walk past my mom and stepdad’s room. When I got there I saw the door was cracked a bit and i heard my stepdad moaning a little bit and right then I knew they were having sex. I decided, being a good prankster that I’d walk in on them and embarrass the fuck out of them.
