She works for an insurance company and lives with her younger brother, who tends to be sick. One day, a mistake at work causes damage to the contractor of the rental management. I don't want the company to know my negligence, but I offer to take care of my personal belongings to a male contractor who lives in a wheelchair. The man takes advantage of Mai's weakness and demands help with sexual processing, saying, "This is also a job." At first, I didn't like it, but as I continued to do shameful acts and vaginal shot sexual intercourse, I felt the pleasure of being ordered, and I fell into an obedient sex slave.
