Rui starts working part-time as a caregiver at a nursing home. Although she experiences sexual harassment, she continues to do her job every day. However, an elderly researcher who was once a university professor takes notice of her and uses his self-made hypnosis control to remove her resistance to anal stimulation, implanting it as an erogenous zone.
