I have been caught so many times, and caught others, it is almost pleasurable for me. I often masturbate on my belly prone, as you would know if you read my submission on who taught me to masturbate. I was in sort of a youth home, whatever it was, a dump for wayward teens, and they (the staff) had this weird thing for catching kids masturbating, and stopping them. I think they made a point of trying to catch a kid as they orgasm.
Well, I had that happen already, in my first ejaculation, and didn't want that again. They didn't even want kids to have wet dreams, let alone masturbate. I was about 13, and after watching them catch kids masturbating, and woke one kid up in a wet dream, I was determined not to get caught (again). But I did. I tried a mop closet, where I succeeded before, but this time (after not ejaculating for about two weeks - pure hell for a 13 year old) I was yanking away, and the door comes open and the guy pulls me out into the hallway, in front of several boys and girls, pants still around my feet and hard penis in my hand.
He held my wrists, presumably so that I could neither masturbate nor cover my throbbing penis, and scolded me for breaking the rule. Because I was so close to orgasm, but the trauma of being caught softened my penis, I was aching and had the infamous blue balls. Later that night, in my sleep, I woke to a rather shuddering wet dream, to the amusement of the boy in the bunk next to me. He was no longer amused when he got caught rubbing it in bed a week later. The event of being pulled out into the hallway with throbbing erection did attract at least one girl, who later gave me a wonderful blow job and masturbated to orgasm about a week later.
