I get very erect when I'm uncaged every week or so for a supervised shower. I'm so tempted to jerk it but my dad watches and I would be severely punished. 🙁
I have to wait for it to go down or he pours cold water on it and then locks me up again.
It constantly tries to get hard, especially at school when I look at hot girls, and it dribbles pre-cum constantly my underpants are always stained and soaked.
