Maybe

Surely they would not have you continue if the women were suffering with diarrhea. But he had no way to ask the doctor with this sweaty lady sitting on his mouth and his tongue up her messy colon. After scooping out the nasty shit and bacteria mixture for awhile, the doctor and nurse on either side of the lady lifted her shoulders and he felt the sweaty butt relieve his face from her weight. That's when he spoke up.

"So I guess you guys are going to have to ........."

Blam! The lady's ass slammed back onto his face. Nurse White leans over, her breasts swaying, and says, "Stick you tongue up and keep is stiff." More butt drops onto my tongue caused it to drive deeper into the lady's asshole. After five times, they let her sit on you face and you can taste the brown sludge as it oozes down your tongue from the dark cavity of her anus. The taste is so awful that your stomach is lurching and wants to throw up.
