I've most I've jacked with is 2 other couples....6 of us total, with my wife.
The most guys only was 3 besides me.
Was fun, to say the least.

When I was about 12 I had a very naughty friend. He taught me to pull down my shorts by the side of the road as cars went by at night.

Which led to....

I found a place where I could JO across from a Foster Freeze --which years ago like McDonalds. Anyway there was a shed across the way and I would pullout my penis and JO where the workers (girls) could see me. It's a wonder I didn't get in trouble, but never did.

Jackin to a group would be a fantasy come true. It would be especially good if there was a mix of men and women and they got so turned on watching my masturbate that they started to go at it themselves.

I would love to jack off to an audience so long as some of them were female.
It has been a fantasy of mine for some time.

I was taught how to jack by two friends who I was spending the night with when I was 13. They started stroking and when I asked what they were doing, they taught me by having me get naked then imitate what I saw them doing. I had never had an orgasm before and when it happened, I was very surprised, and they both had a good laugh.

Later, my wife and I were playing truth or dare with another couple. After we were all naked, my dare was to masturbate in front of them. I'm somewhat of an exhibitionist, so it wasn't hard to talk me into it. I stood by the table naked in full view of my naked wife, and my naked friend and his naked wife, who found it very interesting. After I came, it was their turn, and they all chickened out! I still had fun!

I would love to jo with a group and be watched and take turns watching each other, especially if it was a mixed group of guys and girls. I've been watched once by a room mates girlfried, which was hot.

I was first caught rubbin at 9 by my sister who is five years older and a wonderful whore. She told the babysitter what i was doing and the babysitter took us into moms room. She was just barely older than my sister. She pulled my shorts down and laid me on the floor after sucking me for a bit and my sister stripped and took my virginity. I wish i could do it again. I didnt cum yet but she was in my bed getting my morning wood. At thirteen we stayed a couple weeks with a friend of moms. My sister would finger herself all day on the couch. She pulled those shorts open to far and i had my mouth sucking her off. I shoved my cock inside and we fucked for a while i pulled out and she sucked so hard i exploded my first load in my sisters mouth and she swallowed.

When i was 14 my buddy would watch eachother masterbate and try to cum at the same time. Normally his 16 year old sister would come in. But he leaned over me and started sucking me and shoved his cock easily so i could suck him off down past his.balls. And i was so horny and into it that when his mom came in. She loved it and was rubbing her pussy in seconds telling us to cum in eachothers mouths. Andwe did many times after i even fucked his moms huge pussy while mom watched. I wanted it!!!!

The closest I have cum is in the Jacuzzi at Desire in Cancun. Public sex is allowed. we were in the tub and I was sitting on the wall, my wife between my legs. She turned around and began to suck me off. After a while it was a really serious blow job and I was willing to cum but she wanted some pleasure too and left the pool for me to follow her to the beds that surrounded the tub. Here was the worst part. I was sort of embarrassed to climb out and walk the 50 feet to the beds with a raging hard on. I just sort of figured what the hell and went for it. I know all eyes were on my cock when I walk over to the beds. Not an unpleasant feeling but I had never been on public display like that before. I have been naked in front of hundreds of strangers and friends but never hard. I am just average, no pornstar but I was really hard.
We did a 69 on the bed and then she rode me cowgirl and I came about a quart. She slid up and sat over my mouth so I could drink our cum. This took the crowds breath away I guess since they clapped when we were finished. Not a public jerk off but much more satisfying and tasty too.

I've been lucky enough to get to do this for real also, so hot & I still jack off just remembering it

I think it would be so hot to have the opportunity to do this. ESP of there were others in the crowd jerking or fingering as well

I do it all the time--via webcam!

i do it for one person all the time, but id love to do it for a group some time, maybe even in public, god that would be amazing!

I had my wife watch me stroke my cock for a long time last night, after fucking her for about 2 hours. It was a very hot experience, she teased and talked to me the whole time, exhorting me to cum at the end. loved it.
