Mine was a quick in the gym, showers. I'm married and straight. I saw this guy go into a shower stall, and he kind of wave on the way in. So i went in and closed the door. I was nervous and then I got a glimpse of his cock. It was awesome. He just said 'suck my dick if you like' I looked at his cock as it grew from his fit as body. I actually got down on my knees in the shower and started sucking his cock, I tasted his big knob and kept going. He then grabbed my head firmly from behind and just pushed half his cock down my throat. I was getting into this, he was hard as rock. i sucked and licked and rubbed his precum all over my face. With no warning at all he started to cum, half in my mouth and my over face and just kept pumping his cock with his fist, draining it. He then pulled me to my feet and licked my lips and mouth. He then pulled me close and wispered in my ear,'come back to gym 2moro, same place and I'll bring some lube and I'm going to fuck you in the arse. So I did, wife don't know but I now love really dirty male to male arse fucking.
