Gerosu series in which girls play with M men with all kinds of bodily fluids such as poop, vomit, pee, and nasal discharge. The girl this time is her younger sister Momo Kusakari. However, despite her face, she actually has a devilish personality. She chews the vomiting vomit herself and transfers it to M man's mouth, and uses a hose to exchange vomit many times. Unprecedented reverse vomiting of the actor who can not stand the excessive persistence! Despite this, Momo-chan continues to make the actor drink and eat filth, regardless of the fact that the actor is getting weaker, saying in an anime voice, "No, no, you have to eat." There are also merciless continuous puke attacks and mouth-to-mouth coprophagy.
