Goddess Amirha has a shit fetish but she does not like it when her house is a mess. Other mistresses like a messy scat fetish but she prefers a clean one. That is why she made her slave place his head in an improvised toilet seat for her to sit and shit into when she was shitting into his head, face and mouth. When she was done, she made him clean it up and leave it as clean as she found it.
