Torture Record: Women who became domesticated slaves

In a room in the basement where training enthusiasts gather, women are kidnapped and confined and trained to women who have their own sexual fetishes. The act is subjected to various tortures depending on the men's hobbies. An ordinary woman is tied up, her genitals are played with and violated. Some women are tortured by water...and others are tortured by suffocation... The desires of men who transcend sexual impulses escalate without knowing what they are.
