Reminds me of when I was in high school (14-17) sitting in the back of certain classes, undoing, unzipping my pants to take out my erection like this, and rolling down a reservoir-tipped condom to the base, but pushing back my pubic and shaft hair so it wouldn't get pulled before jerking it with my right hand. One time a male teacher caught me as I was in the midst of filling it. I was afraid he'd call or write my parents about it, but he didn't.
