About 3 years ago I was working security at a mental hospital.
We had normal patient rooms, and 2 "padded rooms" for the really crazy fuckers. Got in a black guy - about 30 years old. The doc says to put him in the pad room. Says the guy masturbates constantly.
He wasn't lying. Literally every 30 minutes this guy would whack it until he was finished. The had a HUGE jar of vaseline they gave him. He didn't just lube up his dick, he'd rub a handful of vaseline over his entire body from the neck down before he'd give himself a 3 minute hand job. One of the night shift nurses got the bright idea to take away the vaseline...because he can't jack off without it right? Wrong - after about 6 hours without the vaseline he was bleeding from his cock...but couldn't stop jerking off. They gave him back the vaseline.
I don't know how this fucker could do it. Every 30 minutes 24 hours a day. He would wake up every half hour at night and jack off. Medication didn't help him. If a nurse (male of female) was checking on him when the time came, or his mom or brother were visiting, he'd whip it out and stroke it.
We (security) didn't want to touch him, because he was always lathered up in vaseline. The one time I had to touch him (when he started jacking off while his mom was in the room) I used a towel to grab his arm and tell his mom to get out. Disgusting.
