The popular writer Sawaori is busy with her writing activities and is troubled by shoulder pain due to her ample chest. She often uses business massage services. The masseuse she has been receiving treatment from recently, Shijima, is outwardly a skilled masseuse, but is actually a professional in the art of seduction, skillfully stimulating erogenous zones while leading her down that path. Stimulated by Shijima's treatment, Sawaori is deceived by his eloquent words and becomes a captive of anal pleasure.
