I lived in the inner city and every summmer I would go to the 3 swimming pools in my area and play grab ass with the guys.
I especialy liked to grope the older 15 to 17 year old guys's crotches. They would get a hardon and I would jack them off and they would jack me off. I would jack off as many as 8 guys a day. In fact it became a game amonst us.
It sure was interesting seeing a guy's cum spurt in long ropes of cum wiggling back and forth in the water. It was worth jacking them off to see this.
I did this from 13 to 18. When I was 13 I couldn't get enough of spurtin' big cock. At 18 I had enough and got married shortly after my birthday.
And you know what happened? While in the Army I would mutually jack off with the guys in the pool because my wife was pregnant and didn't want sex! This mutual jackin' went on untill I got discharged. O boy!
