Sweaty and dirty in the gym bathroom
I worked out at the gym, and when I was really sweaty, I went to the public restroom.
Even though a lot of girls from the gym were coming in, I got naked and started fingering my ass.
Then I licked my fingers, which were covered in shit, and I got so turned on by the taste that I lay down on the toilet, raised my legs, and started masturbating my clit until I squirted, making a mess of the whole bathroom. But I didn't care because I was so horny.
I went back to fingering my ass, and with the shit I'd come out, I got my ass all dirty. It smelled awfulshit, pee, vaginal discharge, and sweat.
After I finished, I just wiped myself a little with wipes to get rid of the excess, so I'd still smell like shit even after I leftshit mixed with sweat.
