Konatsu helps her timid mother run a public bath and finally bans a gang of mobsters whose harassment and intimidation have driven customers away. The men retaliate by targeting her body, overpowering her in the sweltering bathhouse and repeatedly forcing sex on her until she is dizzy from the heat. After discovering her enormous breasts, they make her serve them with titjobs and cover her face in semen after messy oral sex. Day after day, sweat pours from her body as repeated creampies and exhaustion blur her mind. Eventually pleasure overwhelms her resistance and the brutal group conditioning leaves her completely submissive. Her newly trained sexual “hospitality” becomes notorious, and the old bathhouse supposedly never lacks customers again.
