Saki Sakura, a high school girl, starts experiencing physical discomfort from her daily club activities and visits a massage parlor for relief. She is attended by a skilled middle-aged masseur. The treatment begins with her feet and moves up to her thighs, gradually progressing to her buttocks and sensitive areas. With her skirt lifted, his fingers slip inside her panties. Shy by nature, Saki cannot bring herself to say no. As her big tits are vigorously kneaded, she becomes overwhelmed by intense, deep thrusting motions that penetrate her womb. Her oil-slicked nipples become hypersensitive and orgasmic, and with the aid of a vibrating machine, she begins to squirt uncontrollably. Unable to suppress her pleasure, she moans and writhes in ecstasy. Enchanted by the sensation, she finds herself returning to the parlor again and again.
