Sumire has long harbored deviant desires, yet in practice, she's an anal beginner—only ever having experienced fingers in her anus. Her fantasies are far from trivial. Once training begins, she surrenders completely, becoming a true masochistic woman devoted to serving her partner without limits. Unexpected public exposure, humiliation, and intense anal training push her to the edge, making her eyes glisten as she cries out in pleasure: "No, no, ahh—ahh—ahh!" Her ecstatic reactions reveal the deep, hidden desires buried within. A passionate and pure exhibition of raw masochism, captured in this intense work by Yabu Same.
