A new oil esthetic clinic promising to restore the youthful fullness of breasts has opened nearby. Wanting to stay beautiful for her husband, wife Asahi decides to become a regular client. On her first visit, Asahi receives a massage from a suspicious male therapist. His indecent, skillful fingers knead her breasts in ways unimaginable, engulfing her in overwhelming pleasure. Captivated by the sensation of having her breasts touched by another person for the first time in ages, Asahi grows increasingly dependent on the clinic. Lost in the ecstasy, she continues to experience unparalleled pleasure again and again.
