The act of two women saving up their feces for an entire month, as the feces reach the peak of methane production they climb in and begin an act so vile. The two women begin taking clumps of feces and inserting it into their rectums, vaginas, and mouths.

My mandingo party was asked to help in a Two Girls, One Swamp party. It was a little smelly.

a wonderful and heart lifting story about three best friends. these three best friends (the two deers, bilo and sloopy, and one cat,MEOW) go on an adventure to the forest where they run into Bark, the dog.

A porn that involves lesbians causing each other to vomit, then playing with it before ultimately the one defecates into the other's mouth, and they traverse it between their mouths and so on.
