Never had until, one evening I met a younger guy at a parking area. He got in my truck, and we both sat, almost facing each other holding our own dicks still in our pants. As if on cue, we both leaned over a little and started rubbing the others, still in the pants.
I looked at him from only 6-8 in and, without really thinking about it, leaned over and kissed his lips. He smiled and said YEAHHHH and kissed back. There, for about 15 min, we made out like school kids, deep tongue and all, while we each took out the other's cock and stroked it. I was getting close, so I leaned over and took his in my mouth and had him squirming in the seat before letting him cum! Saving a mouthful, I straightened back up and shared it with him. He, in turn, did the same for me.
The taste of our cum and precum was exciting. At the time the sharing was a first with a guy, and seemed to be very different than with a woman, for some reason.
All in all, a wonderful interlude which must have been good for the young guy because we did repeat it several times I have since tried to make it a regular whenever the other guy will cooperate.
