Reina, a recent graduate working in an office who has just started living with her boyfriend, falls at work and hurts her back, so she calls in a freelance masseur, Okamoto, to her home. His friendly demeanor initially meant the treatment, but as he continues to give her soothing massages using powders and oils, the boundaries gradually become blurred. Supported by her boyfriend, Koichi, Reina finds herself unable to resist Okamoto's techniques, and eventually, what was supposed to be a one-time thing crosses the line, and she becomes engrossed in a physical relationship with him.
