I've been married for about 2 and a half years and my wife doesn't know that I am also attracted to men.
When I invite mates over my wife is usually out or upstairs so we pretty much get the house to ourselves.

This one friend who comes over a lot is really into videogames and so am I so we usually just play games and chill when he is round. He is however really competitive and we always used to make forfeits for the guy who lost the game.
You can probably tell where this is going but they got more and more sexual. We were playing FIFA most of the time and the thing was he was quite a bit better than me. I'd get the odd win here and there but for the most part he would beat me.

One day when we had the house to ourselves he made the the dare 'The loser has to touch the winner's Dick'. The game went on and of course he won. I was a bit embarrassed to have lost, he pulled his dick out and I remember being a bit surprised at how bit it was, not massive but quite big and I touched it with one finger.

The next game he upped the stakes big time! 'The loser has to give the winner a handjob'. Oh shit, I thought. But the winner gets to decide the stakes so I had to go with it. This time in the game he's thrashing me, I mean beating me really bad, I'm getting butterflies and my face is getting flushed with embarrassment. All throughout the game he's making comments and grinning about the handjob he's about to hey which makes it even worse!
The game ends and he pulls out his sick again and I notice that he's already got a bit of a semi. I'm nervous as hell bit slowly put my fingers around his dick. I slowly start stroking and he's getting really hard really quick. I look over at him and he's got his eyes close and let's out a little groan. This freaks me out a bit and I stop and he says that I'm not done. I have out a nervous laugh and said he didn't specify how long I had to do it for!

Guess what, he ups the stakes AGAIN. 'Thr loser has to sick the winner's cock until the winner cums.
"Shit" I thought, what are the chances I can beat him? Needless to say during the game I'm beginning to lose again and my heart is pounding. He's saying things like "You're gonna be sucking my dick if you carry on like that" and my insides are going nuts with butterflies. I keep imagining what it will feel like etc and I look down and I've got a hard on! The whole humiliation of the thing was turning me on so much and by now he's absolutely thrashing me again!
The game ends and he turns to me, not smiling this time but looking really intense and he can't get his cock out quick enough, he makes me kneel while he sits on the couch and this time o just go for it. My heart has never pounded that hard! I slowly put the tip in my mouth and began to suck. He moans instantly and is getting really into it. Before long I'm getting into it as well sucking and stroking his shaft, a couple of times even seeing how far I could take it down my throat.
This goes on for a few minutes and he says he's going to cum, I get faster and more intense and he squirms as he busts his load in my mouth. I swallow quickly because I've never had cum in my mouth before.
Afterwards he mentions how great it was and I'm feeling awkward and really turned on and he can't stop going on about how great I was at sucking dick.

After that every time we played the stakes were similar, I lost every time and it got me so turned on, being beaten and humiliated and it turns out I love sucking dick as well. I began to just lose on purpose and saying things like 'oops' or 'silly me' and try and be sexy with it when I let a goal in or when I lost which felt weird but the humiliation turned me on so much. Every time when the final whistle went I'd be on my knees as quick possible.
I'm thinking about upping the stakes...
