Sunao lives with her mother. Besides working at a factory, she also works as a caretaker for their landlord. When her mother's health deteriorated, Sunao decided to take over her role as the landlord's home health aide. Taking advantage of the landlord's helplessness due to being confined to a wheelchair, he repeatedly engages in sexual harassment. What started as simple caregiving gradually escalated into increasingly demanding requests, culminating in a creampie sex session. Although Sunao initially resisted, she gradually transformed into a sex slave.
