Kokoro is a daughter who pleads with her landlord to be a helper in place of her mother, who has fallen ill after her father's disappearance. She repeatedly sexually harasses her landlord, who is in a wheelchair, and takes advantage of Kokoro's request, "I'll do anything." At first she was only a caregiver, but her demands steadily escalated, and she ended up having vaginal cum shot sex. At first, Kokoro showed resistance, but she gradually turned into a sex slave.
