Trading Sexuality

June last year. My wife had me suck off an older man to satisfy a sexual fantasy she had.
Now several months on, I'm not only sucking him off on a regular basis, he's also fucking me two or three times a week.
We were at a party in June when an older gay man took a fancy to me. My wife and I had had a bit to drink, so when she heard him trying to seduce me, she couldn't have been more active in getting me to suck his dick.
Only when I eventually did outside, with my wifes constant encouragement, I found I absolutely loved the taste and feel of his cock in my mouth. The thing is, because I got into it and I didn't struggle to deep throat him, my wife kinda lost interest and went back inside.
That only encouraged me to make him cum in my mouth so I could experience his man juice.
When he came, I greedily swallowed every drop and even shared a long passionately kiss with him.
We swapped numbers and I promised I'd meet him again.
And since June I've enjoyed him fucking my mouth and especially my arsehole as much as we get time together.
If it wasn't for my wife, I doubt very much I'd have experienced gay sex. But as it is, I'm now considering leaving my wife and moving in with a highly sexed guy who's in his early fifties.
