Ace Urine Appraiser

Ace Urine Appraiser is a scatological Japanese erotic adventure game about a man who likes to consume the urine and feces of women.

Set in a fantasy world, the player takes on the role of this cursed protagonist after he is entrusted by a princess to stop a river from being polluted with the waste produced by the residents of a village. Fortunately for the protagonist, he has a better idea of where the waste can go: his own mouth. He journeys around the village, putting himself in situations where he can sample urine and feces whether it is left in buckets or directly from the source, hiding himself in toilets for women to defecate on his face.

There are multiple endings that may be achieved depending on the player's actions throughout the game.
