I've been fucking my best friend's father behind her back.

We've been friends since college, so around 12 years.

She's one of the first people I actually came out to at age 18 and she was fully supportive. We went out to gay bars, moved in together for awhile, told each other everything.

Anyhow, around four years ago we started playing tennis with her father.

In the beginning, I saw him like an older brother. Totally different from me. Former jock, into sports and beer. He still wears his old letterman jacket. We didn't have much of a conversation when she wasn't around and I think he only tolerated me because I was his daughter's best friend. But then the more I hung out with them, the more at ease he became with me.

About a year ago, he joined my gym, near my house. Then we went go out for shakes or he would stop by after work-out for a beer.

One day we both got really drunk and he made a move at me. I was really surprised because I never suspected anything, but I was also drunk and he's hot, so we ended up making out and I blew him. Long story short, he's been coming over after work-outs at least once a week to fuck. My best friend doesn't know. She works way on the other side of the city and thinks it's swell that we hang out without her.

I feel guilty but I won't lie. I really enjoy the sex.
