To realize her dream of becoming an idol, Rina left home and is currently living with her despised uncle. Ignoring the perverted uncle's sexual harassment, she coldly looks down on him and treats him rudely. Fed up, he resorts to despicable methods to force a sexual relationship. He secretly mixes diuretics and aphrodisiacs into her water, causing her body and mind to be overwhelmed with desire, leading to a breakdown of reason. Unable to stop urinating, her urethra ruptures, and the strange sensations in her body begin, causing discomfort in her vagina and forcing her to humiliatingly beg, 'Hug me.' Rina exposes her lewd face and moans obscenely, becoming the epitome of a female.
