Mio Ichijo, a resident of the apartment, brought a man into the house while her husband was away and had an affair. One day, her janitor Sugiura, who was suspicious of her behavior, saw her except for Mio's affair. She takes pictures of Mio who is restrained and trained in SM and is lustful. The manager uses the photo to threaten Mio and train her to be an Irama sex guy of her choice. In addition, Sanada, who was Mio's affair partner, also moved to the same apartment, and she was doing Irama training while her husband was away.
