Kasumi lives with her mother. Her mother is often sick and the family is struggling financially, so she offers a job as a helper at the home of a landlord who lives in a wheelchair in the hope that she can add to the rent even a little. However, the landlord is a lewd person at heart, and demands that the rent be delinquent and that it be dealt with below. It escalates to,,, and even strong ● vaginal shot sexual intercourse. I'm vulnerable and obedient.
