Sakura, a high school student, takes a part-time job at a nursing home during her summer vacation to help her father with his work. Sakura is a kind- Kokoro Sakura who volunteers to care for her. However, her kind Kokoro is taken advantage of by the men residing at the facility, who take advantage of her. They sexually harass her by forcing her to give a handjob under the pretext of a bath, forcing her to deep throat, restraining her in a wheelchair and making her cum with toys, inserting a stick into her vagina, urinating in a urinal, and drinking her urine. Sakura is violated harshly. Her hellish caregiving continues, as she is showered with water in the nursing bath and submerged in the bathtub. Finally, she is fucked repeatedly. A masochist who becomes an outlet for the men's desires. The process of the beautiful girl going from being genuinely reluctant to succumbing to the cock is vivid.
