mai, who works for an insurance company, lives with her sickly younger brother. one day, a mistake at work causes damage to the contractor of the rental management. i don’t want the company to know about my negligence, so i offer to take care of my personal belongings to a male contractor who lives in a wheelchair. the man took advantage of mai’s weakness and demanded her to help with sexual processing, saying, “this is also a job.” at first, he didn’t like it, but as he continued to perform shameless acts and vaginal intercourse, he felt the pleasure of being ordered, and fell into an obedient sex slave.
