Is it normal that i secretly cum on girl's things?
I noticed that I recently got an obsession over cumming on girl's stuff. I've only done it to one person so far, though.
I went to a friend's house, and when I went to the bathroom, I noticed that my friend's sisters retainers were there. I quickly jacked off so that I could cum on her retainers and toothbrush and then left.
I felt kind of bad about it, but it made me kind of horny and I don't think she'd be too mad about it. Is it normal that I did this?
