Rui lives with her mother. Her mother is often ill and has difficulty working. She begs her landlord to let her work as a housekeeper to help with the household finances. Her wheelchair-bound landlord takes advantage of Rui's offer to "do anything" and demands that she not only take care of him, but also satisfy his sexual needs. She gives him handjobs, titjobs, blowjobs, and even raw sex. As Rui becomes obedient to her landlord, she gradually learns the joys of being a woman and becomes content to be his sex slave.
