I have been to prison a few times, and, have been seen naked by female officers, nurses, doctors, admin. staff, etc.
I have been seen whilst I was naked, in the shower-room, adjoining the staff-office, on the prison hospital wing, as the dividing wall is actually made entirely from glass, to allow staff to observe prisoners who use the showers, etc.
So, I was naked, stood in the shower area, aware there was no door or screen between myself and the view of the nurses, and, female officers, which was humiliating for me, as my penis is small, and, I have ginger pubic hair.
At least four female prison staff were watching me that say, and, I began washing myself under the shower, and, when I came to actually washing my genital's, I soaped them up, and, with the staff watching, I began to get an erection, which they noticed, and, I turned to face them, with my fully-erect ginger cock in my right hand, and, started to wank myself off, right in front of their eye's, and, it only took me around 30-40 seconds of masturbating before I ejaculated as they watched me!
