Gulping Down Liquid Shit After Gym

Katherine is just back from the gym with a nasty gut. That protein shake went bad inside her -- liquid shit exploded out, and her slave had to open wide. Farts, sharts, full-on sewage -- he swallowed every hot, gurgling gulp. Katherine feels her slave's body shiver with every liquid fart dripping down her throat, but she doesn't even care. His mouth is a sewer pipe.
