Teen girls are overly curious and horny. My daughter was caught watching me use my penis pump. And I caught her looking at porn and masturbating late at night.
It's a natural thing,the question is did he do it so you would see him? Did he know you where watching him for do it? If not did you enjoy seeing someone masterbate?
Well, it depends where ya caught him. I think that people who do it where it's easy to be caught secretly wanna get caught. Yeah, he's shitty for doing it where it was easy to get caught. Doors have locks for a reason.
