Miku, who lives with her mother, started a part-time job to support her surroundings for a wheelchair-bound landlord in place of her sick mother. However, the infatuated landlord Jijii develops an unbearable habit and makes the following demands. Miku cannot refuse to act strongly with her hands, damn it, deep-throating Irama, and eventually combining vaginal and oral sex. Subsequently, the landlord's immoral behaviors escalate; initially, he should have hated it, but as the landlord continues with it persistently, he obediently accepts the life of a sexual slave.
