In this work, a beautiful girl with a hint of innocence is stripped naked, restrained by shiny black iron restraints, and her exposed anus is violated mercilessly. The 21st sacrifice is "Mirei Nitta". She is suddenly attacked on the face and nipples, and whipped with an anal hook stuck inside. At the same time, she is subjected to intense anal fucking. After that, her anus is forcibly expanded with an expansion pump and various toys, and she is suspended in mid-air in a 3P anal fuck. Then she is subjected to an enema torture while enduring the heat of a candle. A mysterious liquid is repeatedly injected into her anus, and in this extreme state where she is completely exposed, she self-destructs and sprays it all over her face.
