A pure and innocent college student is deceived by a corrupt esthetic salon. Visiting for the first time, she learns the salon uses aphrodisiacs to activate female hormones and relax the body. Despite her suspicions, she changes into the provided treatment wear, which is so skimpy that her breasts and pussy would easily slip out without her hands covering them. Her young yet ripe H-cup body is loosened by a daring massage... until finally, her pussy is spread open. She falls into a special sex treatment with a penis, twitching and convulsing in an orgasmic frenzy. Trapped in the pleasure swamp of this corrupt treatment, her hidden masochism awakens—her cervix is conquered, and her body is transformed into an abnormal constitution that constantly climaxes and squirts. The girl who never smiled finally breaks down.
