Mizuki is a good wife who takes care of her sick mother every day. However, she has two homes. One is with her husband who is submissive and a complete masochist...the other is with a sadist who likes to dominate. It's hard to go back and forth between the two homes, but both men are rich, and Mizuki is very happy because she can satisfy her desires and also raise the money for her mother's medical expenses. There's a lot to see, including 4-way fucking, cowgirl creampie, deep throat, titty fuck, and forced vegetable masturbation!
