When I was thirteen I came out to my parents. Two years later my Dad came out to Mom and me. She was upset at first but then decided she was OK with it because it explained why they drifted apart. She was already planning to divorce him. So they separated and divorced and were both very happy. We still spend holidays together except that Mom sleeps with her boyfriend and Dad sleeps with me.

Yes, you read that right. When they got divorced they shared custody but the judge said I was old enough to choose and I chose both so we alternated. I liked the school where my Dad lived better but made up for that with mom by spending a lot of time with her in the summer.

Well Dad only got a one bedroom apartment with one bathroom and one day I was sitting on the toilet trying to take a dump and Dad walked in naked holding a towel and got in the shower. I gasped at the sight of his amazing cock. It was huge and I became optimistic about my genes after that. All I could think of was sucking that amazing cock. Well Dad figured it out after a few weeks and invited me off the sofa and into his bedroom to view some hot gay porn. every video was about gay men having sex with their teenage gay sons and half of them looked younger than me and I was only 15 at the time. I found myself gawking at Dad's immense throbbing cock bouncing up and down and he told me I could touch it if I wanted to. I wanted to. Actually I wanted to choke it down my hungry throat and I wanted him to shove it hard up my cock hungry ass.

I just went for it. I grabbed it and went down on him. He called me a dirty little faggot and demanded I suck him off. His mouth got really filthy and that turned me on and the more he verbally abused me the more I wanted his hard cock in me. I'd never had a cock in my and was half scared but I'd been practicing with a dildo for a while so I thought I could handle it. I was wrong. Dad accepted my invitation to fuck my ass, didn't bother with a condom and just shoved his cock up my ass. It hurt badly, very badly. I thought he split me open. I underestimated how bad it could be. He realized he was hurting me and pulled out immediately. He flipped me over and drove his tongue up my ass. His tongue soothed much of the pain. Turns out Dad was not an experienced ass fucker.

We tried again a week later this time Dad slowly and gradually stretched me with well lubed fingers and dildos and then had me just sit down on his cock and take what I could. I was able to better relax and was amazed when I took him all the way up my ass without any pain. It burned in a deliciously tingling way but not in a sharp painful way. I could feel his head rubbing against my prostate as he picked up speed and intensity. He came up my ass a few minutes later and amazingly stayed hard and then amazed me even more when he bent himself in half and sucked me off with his still hard cock up my ass. Seems he'd been sucking himself off for years behind Mom's back.

The best blow jobs, I have learned, are ones you get with a big hard cock up your ass. Between that and his massaging my balls I had the best cum in my life. I imagined he was sucking me while another guy was fucking my ass.

So that is how Dad became my lover. I don't think she knows. But she must suspect it. A gay son and gay father living together in a one bedroom one bath apartment sharing a bed and being openly over affectionate with each other must seem suspicious. But she has never said anything and seems quite happy that Dad and I get along so well together. Maybe she doesn't want to know. Maybe she just keeps her eyes closed. Maybe she knows and is happy her two boys keep each other happy.
