Did you know the anus is constantly leaving its mark? On sheets, on beds, on chairs, on couches, on panties and underoos, on pants or shorts if you’re commando. Hershey squirts? Skid marks? Even if a fart seems successful in the sense that doodoo actually never came out, some excretion has occurred. So if you smell your underwears or where you normally sit, unwashed, or if you sleep nude, there will be stank on those undergarments, chairs, couches, beds and sheets. Doing the doggy too, if you pay attention, especially, if you like morning sex, you can smell the stank.
