I have done this several times and find it extremely horny, just being parked up and the anticipation of other guys turning up looking to play with cocks gets me hard
Yes, I know that some guys go there to masturbate (and some women). I would masturbate, but with another guy I always want to finish by taking his load in my mouth.
I want to. But I would never meet a stranger I do not know, at a place no one knows I am going to. But disregarding that for just conversation... I have the desire to - but think that perhaps the fantasy and idea of it is 100 times better than in real life.
Related to this... there is a documentary on Netflix, don't remember the name...anyhow, in it was an episode about couples going to a "sex party". The host is a paid organizer who has a nice house with a pool etc. People are encouraged to swim nude, mingle with each other and explore each other. And two people can go to a few private rooms to have full on sex. Anyhow... usually 90% or so of couples who attend for the first time end up doing nothing. Virtually all "action" that takes place is people who frequent these parties. The documentary interviewed several couples and they all pretty much said the same thing... in their minds they thought it would be so much fun and spice things up... but in reality it was weird and awkward. That is how I would bet something like this would go for 90% of dudes.
I love having another cock to jack off with, whether we just watch each other or jack each other. I especially love it when we encourage each other with dirty talk.
Have done it, I met a guy off the Net on his way home from teaching school, he was horny so I got him to show me then asked if I could touch it. Got my hand on it and then wanked him off, all over his trousers. For some reason, and strange as he was on a gay website for meetups, he was embarrassed and we never met up again.
That's what my wife and I noticed. Most people end up watching and not participating. That was fine for her, she's a natural exhibitionist. I was quite shy, the first time at least. Watching my wife flirt with people while she was completely naked was quite a rush. The second time she talked me out of my pants. I wore only a shirt that only gave me partial coverage. After twenty minutes or so of walking around with a hard on that was mostly on display I pulled my shirt off fixture my red face. There were only two other naked guys. The three of us masturbated with several fully clothed spectators watching and cheering as we came. That was a blast!
I started revisiting my bi desires by meeting and parking with another horny frustrated friend. I would drive to find a suitable spot, and have my cock out so he could pull me and I would drive with one hand and pull him. We parked and pulled each other but it wasn't private enough. We tried disguising what we were doing, using a map or something. It was too risky to suck each other off but we really wanted to, so we found an old bi guy with a unit, living alone. Then our cocks got a real workout. I'd do it again right now. It's so much better than just pulling myself.
