The patient of Doctor Odette is very low on electrolytes. She must hydrate him with a piss transfusion, using her piss to fill his ass while she feeds him his own piss. In this strange experiment, Doctor Odette catheterizes her patient and makes him fill the Cath bag. She then turns him upside down and connects the valve of his piss bag to his mouth. But she must now replace the piss in his body with her own formula. She inserts a speculum into his anus and spreads him wide. She squats over her patient and lets her golden nectar flow into his asshole. As her hydration fills him, she releases the valve to his mouth and he drinks from the Cath bag. With his hole and throat full, Doctor Odette rubs his catheterized cock until he ejaculates around the tube!
