Hitotsuma Secret Club, Mizuko Sakuragi, Izumi Hanada

As mothers, as wives, they live a normal but peaceful life. They believed it was a matter of course, and that it was some kind of happiness.... However, I could not imagine that the sex of being a woman hidden in them would disturb its peaceful daily life. When a coffin breaks off with one trigger, the wives fall in love with sexual pleasure as if they cut the coffin.
