IPZZ-137 At a judo training camp, a new female instructor is ganged up on by six students and used as a sex toy.

At a hot spring inn during a judo camp, the new female instructor, Iori, is directed by a power-harassing advisor to let her six male students use her. They crowd around her, fondle her large breasts, and take turns in a relay, with two or three ejaculations each. The video shows a sweaty, humiliation-filled group scene in a closed guest room, with a total of fifteen ejaculations. Iori, played by An Himeka, is overwhelmed by the constant attention.
