Ever since I can remember my parents have never been together. My mom and dad share custody and it's always been great. My mom a dad get along but just don't want to be together.

My mom remarried when I was little and I've always got along with my step dad. My dad on the other hand never got married and as far as I know never has had a girlfriend.

I was 18 at the time, was half ways through my senior year and was enjoying it. I wasn't a virgin, I had sex with my friend more than a few times when we were younger. That is what made me by. Had sex with my first girl my senior year too.

My dad openly admitted one day he hadn't had sex in around 13 years. He worked a lot so had no time to date. He traveled for work a lot so on Fridays when I went over to his house for the weekend he'd get home around 8. I finally one night told my dad I was bi sexual. He wasn't too schocjed to find out. He asked if I had anal and I told him I started doing that years ago.

So that lead in use having sex every Friday night. He says it's so wrong but I told him no one will find out. He hadn't had sex in 13 years at that point so I figured sex every now and then wouldn't hurt. I wait for him on the couch in my briefs till he gets home Friday night. He strips or just drops his pants and underwear then he bangs one out in my ass. The first time I though he was gonna pass out he came so hard. He needed that release. But dang I had no idea my dad was hung and hairy! I still let him fuck my ass to this day. It's just become a routine
