Recently I've started masturbating by finding the dirtiest public restroom I can, be it at a buffet, gas station, kneeling in front of the commode, putting my head inside the bowl and breathing through my nose as I imagine all the other men whose butt holes have been where my face is.

Some of the cubicles I've used are really small and I'm sure the men who come and go as I'm jacking off have seen my knees and shoes. I wonder if they just think I'm throwing up??
