After being dumped by her boyfriend and heartbroken, Momoka moves to a new place where she's suddenly approached by a kind young man named Riku. Feeling lonely, she lets him stay in her apartment. As their cohabitation progresses, Momoka falls deeply for Riku and gradually regains her cheerful, outgoing personality. She starts masturbating in front of him, gives him intense blowjobs until he cums, and her desire for love begins to awaken again. When Momoka finally confesses her feelings, Riku tells her that her role as his pet is over—and for their final goodbye, he gives her a creampie before leaving.
