Pecker Checker

The observers for piss tests who are required to watch the fluid leave your body, so they actually look at your dick as you piss into the cup. Sometimes, they will get so bored after looking at dicks for hours that they will start to mess with people and rub your shoulders or try to make you laugh as you’re pissing.

I thought I was going to skate today but I got selected to be a pecker checker and had to look at dicks all day.
