In a hurry, I entered the nearest bathroom and stepped into one of the stalls. I quickly dropped my panties and plopped my big ass down on the toilet. I sighed pleasantly as I felt piss suddenly stream out of an unfamiliar hole down there. "That's nice, and weird, but still nice." Soon I was done, but I realized that I really couldn't shake myself dry as I normally would do, so I dabbed my crotch with some toilet paper and then stood and pulled up my panties. Finally, I flushed the toilet with my naked toes.
When I stepped out of the stall, I was surprised to find a guy standing at the mirror by the sinks. It was only then that I realized that I had entered the men's room by mistake. Oh well, no matter. No one could see me anyway. I washed my hands and got a closer look at the guy. It was the same guy who had been slapped in the face in the cafeteria when I had felt up that one girl's butt. He was checking out his cheek and sighing as he saw how red it looked. I felt really bad for him. Not only was he hurting, but also he had no idea why it had happened.
