Colleagues Husband

One of my female colleagues invited me to a barbecue a couple of months ago to celebrate her husband's fortieth birthday.
During the barbecue I got chatting to her husband, who asked me straight out, if I sometimes cruised a certain area of a canal for gay sex.
When he said he'd seen me sucking off another guy a few weeks before, I owned up to enjoying men and their cocks.
He knew I had a girlfriend, but still asked me to follow him upstairs in their house.
In their bathroom I got on my knees as he fed me his eight inches and began face fucking me.
I was just beginning to get used to his thickness in my mouth, when there was a knock on the door.
He stopped the blow job, opened the door with his cock still out and said "Hi" to his wife.
She looked down at me, smiled and said "He wants to fuck you".
Before turning to walk away, my colleague and her husband had a very passionate kiss, then she told him "Fuck him good babe, its your birthday".
Walking back over to me, he picked me up, had me lean over the sink unit and pulled down my shorts and boxers. As his tongue began lapping at my arsehole, he said "G was there too that day".
What I didn't know, is my colleague and her husband sometimes fuck in the woods near the canal, and occasionally have other men join them. It was a complete shock to me, as G is such a sweet, usually quiet, but very good looking older woman (39)
Once my arsehole was good and wet from his saliva, he stood up, put his cock to my hole and slowly entered my arse.
It wasn't my first fuck by any stretch of the imagination. In fact I lost my anal virginity to a local dignitary when I was sixteen. (If you want to know who and how, let me know in the comments).
Gripping onto the sink unit, I took every inch of his cock up my arsehole as he fucked me so hard and fast.
Within minutes my cock shot its load and my colleagues husband shouted out he was cumming.
He came deep inside of me and at the same time turned my head to kiss me passionately. When he pulled out, he literally lifted me up and around. Had me lay on their sink unit as he ate out my arsehole again.
I watched him tongue out his own cum, before he eventually stood upright and slid his cock back into my hole.
When he fucked me the second time, he didn't once look away from my eyes and told me he'd love to fuck me again.
My cock hardened just before he came for a second time, so he gripped it and tossed me off.
Cleaned up and back with everyone outside, they didn't say anything, but I knew they knew the birthday boy had just fucked me.
G came over and kissed my cheek saying "I'd love you to call by when he's horny for a boy".
And that's exactly what I've been doing these last nine weeks. Sometimes G's at home when her husband fucks me, but mostly she's working when her husband annihilated my mouth and arse with his beautiful cock.
It works for them, as G's told me, it helps keep her husband's massive libido in check. And I can definitely vouch for him having a huge sex drive.
