This just happened today and I wanted to relate it. I had been corresponding on the net with a guy who worked near where I did. I'm married and have a good sexual relationship with my wife, but sometimes get urges to be with guys. My fascination isn't with their looks or muscles or ass, it's with their cocks.
So I chat with this guy for a while this morning and decide to meet him nearby in a hotel parking lot. When I got there, I parked next to him and he got out of his car and into mine. He's 43 (I'm 35), about 5'9', 170lbs with brown hair and eyes. A generally average guy like me.
We exchange quick pleasantries, but quickly get down to what we were there for. I'm a little nervous, so my cock is only about half hard. I pull it and my balls out of the fly of my boxer briefs and my dockers. He dresses a little less casual for work and I reach over to fish his cock out of his suit pants as he reclines the seat back. His cock is getting up to its six and a half inch length. He's cut with a nice head, but thin shaft. My six and a half inch cock starts to grow. My head is a bit bigger and shaft thicker.
I often lose my bi-interest after I cum, so we agreed I would get him off first. He dribbles some of the lube he brought on his shaft and I start stroking down to his balls, pulling his skin tight and then back up to his head.
I work my hand up and down his shaft, sometimes twisting my wrist as I go down or up. Pretty soon I have him going good and he says he's getting close. I'm concerned about getting cum on my seats, so I brought a styrofoam cup with me. I put the cup near his head, but not over it. My favorite part of doing this is watching the cum shoot out.
I continue stroking him and he starts grunting and manages a breathy 'I'm cumming!' and spurt after spurt of hot, white cum shoots into the cup. When his last shot barely reaches the cup I move it closer and let the rest dribble in.
He sits up and watches me as I furiously beat my meat for less than a minute and blast my cum into the same cup, mixing with his. After we calm down, we wipe up a bit and put our cocks away. I briefly say thanks and he gets out and goes on his way. Perhaps we'll do it again soon.
