Konatsu, a high school girl concerned about growing pains in her breasts, visits a well-regarded chiropractic clinic in the neighborhood where her mother attends. The massage started with the teacher forcing her to wear obscene treatment clothes, despite her gentle demeanor, but her suspicious looks. When her treatment begins, she is caressed all over by her chiropractor in an unpleasant way. With her pure and innocent personality, she suppresses her voice and is unable to reject her, climaxing and failing.
