Takuya is a proud university student, but he looks no older than a high schooler. Naturally, this brings its own fair share of troubles: from being treated like a child to being denied entry into the world famous brothel Soap Land. To make matters worse, his mother is an airhead who never seems to understand his problems, and his neighbour Yuri sexually harasses him constantly.


However, when Takuya's mother catches him masturbating, she realizes the great extent of her son's suffering. Worried he may turn to molestation, she decides to take matters into her own hands. Enlisting the help of Yuri and some provocative lingerie, the two women work together to satisfy Takuya's growing lust, providing their own take on Soap Land right at home.
