I was walking back home, wearing those black and gray tights:

For once, I did not have my cockring (not like on the photo), but let it hang down the leg.
So I was walking, completely flaccid, when I noticed a guy on a bike who triggered my gaydar.
I turn around, and sure he was, stopped, and when he saw that I turned around, he brought his bike on the sidewalk; even though he was not wearing spandex, nor any sports clothes, by the time I got to him, I was fully, very obviously, erect.
— My place or your place?
Neither place was convenient for either of us, so we start looking around for a dark corner… We eventually find one in a lane, behind a dumpster, near a garage entrance…
He did not want to kiss, but I sure was interested by his tool, which was bursting out of his pants…
So, down go the pants, and I do my usual magic to get my dose of cream, until the garage door opens, at which time he came, and started to pull out. By chance, his load was not extreme so none was spilled.
The surprise was intense* enough for me to end up with a lot of pre-cum wetting my spandex. But they were black so it wasn’t much visible (as if I cared…).
We exchanged phone numbers, and we eventually me a few times, both at my place or his place, but at his place, I met some bedouins with which I would hang for a while (but that’s another story — in short, I had great sex with them)…
* One of my most intense jerk-off memories is the first time I decided to go naked in a city park at night when I was probably 18 or 19, in a remote path in the woods. I met two guys, and the memory of the surprise it gave me was intense enough to be a good memory when I have sex or I jerk-off…
