The act of a very obese woman rolling her body up the body of a man who is lying on his back so that the circulation to the lower half of his body is cut off. A very small person or a monkey then plays with his unerect penis.

While fucking, the man takes a shit on the woman's chest. He then proceeds to rub it in with his knees. While rubbing it in and on his knees, he jizzes on her face.
