Natsuki happens to come across a flyer for a free massage and decides to request a treatment. Perhaps because she has not had sex with her husband for a long time, she feels agitated when the man caresses her all over her body. Not satisfied with masturbation alone, she requests a massage again. Unable to contain her excitement, she craves the masseuse's cock and begs for sex. Natsuki is so enthralled by the massage that she immediately makes a reservation for the next one. However, she is confused when an assistant accompanies her, but they take advantage of the situation and enjoy sex together.
