It is a training record of genuine masochist women who applied for training in the SM secret circle. "Miwako" Miwako is an immature masochist who has just graduated from a prestigious private university. She has no SM experience yet, but she has a desire to be confined and trained, and she voluntarily joined this circle. On this day she took Miwako to a villa owned by a member, and she trained thoroughly until the next day.
