MIDA-527 | A girl who never smiles is deceived by an unscrupulous beauty parlor... Her private parts are loosened with aphrodisiac oil and she collapses into an incontinent orgasm. The fate of a female college student who falls into a pleasure massage swamp, En Mochizuki.

An innocent college girl is deceived by a shady beauty salon.

It's her first time visiting a beauty salon. Apparently, the salon uses aphrodisiacs to activate female hormones and relax the body. Though skeptical, the girl changes into the treatment gown they've given her. The fabric is so thin that if she doesn't cover herself with her hands, her breasts and pussy will slip out. Her young, ripe H-cup body is loosened up by a risqué massage... and finally, her pussy is exposed. She falls prey to a special sex treatment using a man's penis, convulsing and trembling in ecstasy. She falls into the pleasure swamp of the shady treatment, and her hidden masochistic nature is awakened. Her porcio is defeated, and she is transformed into an abnormal constitution that causes her to experience constant incontinent orgasms, and the girl who never smiles finally breaks down.
