When I was working I used to go to the gloryhole about 1/2 mile from work at least once per week. I sucked and drained 5 cocks one day during my lunch hour. When one guy was leaving the booth, I looked and saw it was a coworker of mine. Always wondered if he knew it was me.
This is still one of my fav go-to vids for masturbating. Watching the cock go from soft to fully erect, the expert sucking and tongue action, tickling his balls to help the ejaculation, and finally grunting his release. Just the best.
