After maintaining abstinence throughout her stay at a hot spring inn, Narumiya Rika gradually begins to surrender to the pleasures her body craves when exposed to a highly stimulating environment. Teased and tormented with toys in the outdoor bath and restrained in her room, her mind may not yet comprehend it, but her body yearns for the sensations, increasingly embracing the ecstasy of submission. Then, drawn into an orgy with three men during a banquet, she is completely consumed by the world of sadomasochism, screaming and climaxing repeatedly as her masochistic nature fully awakens.
