Hot Springs Geisha

Two sisters involved in rival underworld sex trade factions compete against each other in this tale of elaborate sex antics, Yakuza crime, and bloody revenge.

After the bankruptcy of her foster-father's condom factory, Tamae sets out to make a living on her own and ends up working as a geisha at a hot spring resort. After rising in popularity, a climactic sex battle is held to decide who gets to lay claim to her.

Many persons visit the hot springs resort to try out Reiko's famous vagina with quivering walls, "the sensation of worms wiggling about"... that won her her nickname (Mimizu = earthworm).

Natsuko is so good at using that super-strong vagina of hers that she can fuck guys to death. In the end, she’s pitted against a sexual superman and a showdown ensues. There’s also a subplot about a mad scientist type who needs vaginal juices to create a potion designed to turn Japanese girls black.

A young girl works as a geisha to earn money for travel.
