Before its called on me I'll admit this is an alias.
So I was in a Nordstrom Rack with my family, and we were looking around and stuff and people were trying stuff on, and well, I was bored. So, I said I had to use the bathroom, went in, got in a stall, and started fapping. The door opens, a guy comes in and sits in the stall next to me. I can see some big nasty feet with sandels on them. Anyhow, I'm nervous now cause I hate it when people are in the stall next to me, even when I'm not fapping. I stop for a bit, hoping he'll be quick, but he stays. So I start back up, and just about the time I'm about to finish up, I look to my right (he was to the stall on my right) and I see on the reflective tiles that the bathroom walls are covered in this nasty bald dude looking over right at that moment too, through a crack in between the stall's walls and the bathroom wall, and of course, I see him pretty well, and I realize he can see me, then I see a strange look on his face, and he looks away. He pretty much books it out of there, but then once I get the nerve to re-emerge into the store, I see him right off, and he sees me too. Then for about the next 30-45 minutes, I follow my family around the store, hiding behind clothe racks and such because this guy who saw me wacking it through some damn reflective tiles just won't leave the store. Shit sucked, I had never been so happy to leave a store when we got out of there.
