Keeping It In The Family

Sucking his cock and taking it up my asshole has become my very guilty pleasure.
We both know we shouldn't be fucking, yet he tells me I'm irresistible and now cannot go back to being straight.

We first began having sex when he stayed with us for a few weeks. His home was being renovated, so he stayed in our guest bedroom.
And on a Sunday morning with my parents out playing golf, I caught him masturbating in the shower. Even now I'm not sure if he meant to leave the bathroom door open on purpose.
What I do know, is I found is cock utterly irresistible. I joined him in the shower, sank down and sucked in his cock. From that first taste and feel of his dick sliding over my tongue, I knew I was going to have him fuck me. And so he did with a lot of encouragement from me.

He says he genuinely didn't know that he liked anal sex with guys, and that I was his first. I'm not sure I believe that, but I'm not complaining because when we fuck now, he's by far the best lover who's ever fucked me, and quite a few older men have thrust their cocks up my boy hole.
He's back home now, but I visit his home regularly for sex. I know he's fucking a guy closer to his age. He's a married man who enjoys his cock too.

But my uncle Pete tells me I'm his special fuck buddy. Obviously mom doesn't know her youngest brother is fucking me, but I wouldn't care if she did. After all she's being fucked by one of our neighbors and my dad knows only too well she is.
