Mai, who works at an insurance company, lives with her sickly younger brother. One day, she causes damage to a tenant client due to a work mistake. Mai, not wanting the company to know about her error, offers to take care of the daily needs of the male client who is wheelchair-bound. The man takes advantage of Mai's weakness and demands that she even help with sexual processing. Initially reluctant, Mai continues with shameless acts and intercourse with ejaculation inside, gradually coming to feel pleasure from being commanded, ultimately falling into becoming an obedient sex slave●.
