Kubo undergoes a one-month intensive program to tone her body, preparing for her reunion by receiving an "internal peeling" treatment. At her familiar salon, a trusted esthetician puts her at ease, gradually stimulating sensitive areas until her anus begins to open. Surrounded by sensations she's never experienced before, she reaches climax repeatedly. Despite her shyness, abundant lubrication flows freely, and she becomes completely captivated by the first-time pleasure of anal stimulation.
