This story happened when I stopped by an adult video store and was lucky enough to have this adventure: When I sat down on the bench I noticed the wall next to me had a huge hole in it to watch the guy in the next booth. I stuck in $5.00 and started to watch the video and heard the door open.
The guy sat down and then the light came on in his booth when the movie started. We were both rubbing our crotches and I could tell he was in good shape and well-endowed from the size of the bulge in his shorts. I slid down my pants and rubbed my hard-on through my underwear and my friend next door did the same.
The head of my hard-on slid past the top of my underwear and it was time to really start stroking, as I lowered my shorts and added some lube to my cock. I was beating off my seven-inch hard cock and looked through the hole to see my young friend with his eight-inch uncircumsized hard cock in his hand stroking away. We beat off watching each other for at least 10 minutes and then we both blasted our loads all over the floor of the booths.
