Get the Dirty Snail mug.
When you let a girl shit in your mouth and then you proceed to let her face ride you. After a couple of minutes of intermixing fluids, she rides down your body. The male then proceeds to crawl over the ground smothered in bodily fluids, while leaving a snail trail behind while making noises like Gary. The girl will then take upon the task to become the snail catcher, using her tongue to track the bodily fluids on the ground. When she finally catches the snail, she ends up jerking the snail off, catching the cum with titties. To defeat the snail, she pressures her boobies in the shit-covered face of the man to use the salty substance called sperm to destroy the target. After the snail loses consciousness the mating ritual ends.

When a male ejaculates into a female/male's ass, then they proceed to drag their sphincter across the ground (like a dog with ass worms) leaving behind a trail of shit and cum.
