Recently I found out I enjoyed taking cock up my ass, just as much as I loved fucking girls. After losing my anal cherry to an older guy who works where I work, I then met an older man who to me was the perfect guy.
Slightly taller than me, more muscular, fit and and a very confident top. Straight away after meeting him at the gym, I just knew he was either gay or bisexual. We hit it off and I found myself saying yes when he invited me to his apartment.

Although his cock is larger than mine, they both look very similar. Our looks are similar too and we just got on so well right from the beginning.

Sucking in his beautiful cock, and having him suck on mine felt so right between us. Then feeling his cock slide up my asshole that first time, was just awesome. All afternoon and into the evening we kissed, caressed, sucked and fucked. And each time his magnificent cock became hard, I craved for it to fuck me.

Three times I risked him cumming deep inside of me. yet I just knew he'd be ok. And so it proved. The sex was the best sex I'd experienced up to then and even now, it gets better and better each time we fuck.

Around a month after he first fucked me, mom wanted to know who the special guy was. She knew I was bisexual, and she also knew from me staying over at his place a few times, I was having regular sex with him. Telling her I'd take a picture of him, we actually took some really horny pics of him fucking me, before I sucked on his cum and anal juice coated cock. Once cleaned up though, we took a picture of us sat together in his lounge.

Showing mom the picture the next day on my phone, she went white, then told me I couldn't see him anymore. It took a whole hour of me asking her why, before my mom said "He's your dad".

My dad left us, when I was two. They'd divorced by the time I reached four and he'd just disappeared.
They split because mom found him having sex with a gay teenager. I was there apparently, but was too young to remember. After their divorce and him going missing, mom removed any pictures she might have had, and told me as I grew up, he'd abandoned us.

Over the next few days I struggled with the knowledge I had, but I had to see him again. Going to his apartment, I didn't tell him who he was to me, and that I knew everything. Instead we had some of the best sex of my life, and it was emotional for me when he fucked my asshole so wonderfully, over and over again.

It's been nearly eight months now since I found out. I've told my mom we've stopped seeing each other, and let her know I hadn't told him who I was to him.

That information he doesn't yet have. And even though I've said we have, we haven't stopped seeing each. The sex is still awesome, and if anything it's getting more and more involved.

I know I should let him know who I am to him, and in that respect I am going to talk with him soon. I just have to figure out a way to explain things, without losing him again in my life.
