I work for an insurance company and I live with my sick brother. One day, a mistake on the job causes damage to the rental management contractor. If you don't want the company to know about your negligence, you offer to take care of  a male contractor who lives in a wheelchair. The man took advantage of Mai's weakness and asked for help handling sex saying “This is also work”. At first, I wouldn't have felt any discomfort, but I remembered the pleasure I got from continuing the shameful act and having vaginal intercourse, and it crashed into my body.
