The Fukiishi couple, who have been married for 10 years, came to a hot spring trip with their husband's arrangement. In contrast to my happy trip after a long time, my husband was nervous. That night, when she was enjoying the kaiseki cuisine, Rena lost consciousness immediately after she drank sake. When she wakes up, she is being held in a dark, cold prison and she is informed by her director, Oshima, that she has been sold out for debt. She was ordered to work as an anal slave by Oshima.
