I'm openly bisexual and both my parents who have now divorced know about my sexual preference.
My dad moved to different town when they split up two years ago and I often visit him there.
Visiting his home last month I met a guy my age in the diner at the end of my dads road, as I waited for him to return from work. Chancing it I took the guy back to dads house and began having sex.
Unfortunately I was just about to cum from being fucked, when my dad walked in.
The guy who was fucking me has a great cock, a real thick hard curved cock which was driving me wild. It's a cock which unbeknownst to me at the time, had also been deep up my fathers asshole.
The guy shouted my dads name in such a way, I knew he knew my dad intimately. It was awkward at every level, not least that I came in front of my dad, whilst being fucked by a guy who Inow know for sure has fucked my father too.
We got ourselves together and just before the guy left he said "You guys should get together and let me know when you're both free".
My dad made out he didn't know what the fuck he was going on about, but the wink the guy gave my dad and my instinct, told me that's the real reason my parents marriage failed.
The visit was cut short as I was too embarrassed to stay over for long.
It's still embarrassing when I visit, and only last week as drove upto my dads house, the same guy who'd fucked me sooo good, was leaving my dads house.
