Lolita-style beauty Koko Mimori's final appearance in her retirement release features an erotic storyline centered around raising and training a bunny girl. The film shows her feeding her helpless, speechless bunny girl the cock as a treat, making her perform blowjobs. As the training progresses, the bunny girl gradually learns dirty talk and starts craving cock, eventually squirting copious amounts of fluid. It's an arousing, intimate record of the adorable bunny girl's sexual development—like a mating diary.
