I was living in a large Southern town that had 2 adult bookstores. While both ABS' saw action, there was one bookstore that where a lot of guys went for man on man action. This ABS had 8-9 booths large enough for at least 2 guys. Plus most booths had glory holes that were large enough to put your hand through and JO the other guy or feel up and finger his hole.
I would stop in a couple of times a month to get my cock sucked and dump a load in someone's mouth. One fall night I stopped in and the ABS was pretty busy but I found a booth with a glory hole next to an occupied booth. I went in and took my cock out where the guy next door could watch me jacking. After a few minutes and getting my cook hard, his fingers started to rub the hole, offering his mouth to my cock. I quickly put my dick where he could lick it. I closed my eyes as a stranger pulled my cock and balls in the hole and start working out his reward. I leaned against the wall, pressing and thrusting my cock where he could suck and jack. I let my jeans fall to the floor as he worked over my dick. Since I hadn't JO for a couple of weeks, I dumped a long pulsating stream of hot jizz into his mouth. I didn't lock my door because I didn't care if some watched me getting my cock sucked.
I sat down on the folding chair in my booth to catch my breath before pulling my pants up and leaving. After only 40 seconds, the guy on the other side put his cock in the hole for me. I hadn't pulled up my pants but I reached up and started stroking his dick.
