Today, housewife Sumire once again receives a massage from therapist Ando, softly moaning in pleasure. Ando's skilled fingers carefully knead her voluptuous thighs and buttocks, working from the nape of her neck down to her toes. As he notices her voice growing softer, Ando gently, seductively asks, "Mrs. Takaoka, your husband... is he away again today?" "He's working late again... so I want you to massage me thoroughly..." As if those words were a signal, Ando's massage gradually takes a lewd turn. Relentlessly stimulating her nipples and clitoris, he draws out breathy moans of ecstasy from Sumire. Their affair has long surpassed the simple label of infidelity—it has become part of her daily life, and her husband can no longer satisfy her inner desires. Craving that forbidden touch, Sumire continues to invite Ando over whenever her husband is away, yearning for his obscene, intimate massage.
