Recently, Mio Kuroki has been feeling unusually heavy in her body. Hoping to relieve her discomfort, she agrees to assist a medium with an exorcism. However, under the guise of "exorcism," she finds herself in unexpected situations—her breasts groped from behind, her legs spread open, and stimulated with fingers and a vibrator. Amidst it all, her feminine instincts awaken, and she begins licking the medium's genitals, only to be penetrated immediately after. Moaning loudly, she writhes intensely in ecstasy. Completely overwhelmed by the pleasure, both mentally and physically, she eventually receives a creampie. Surprised that such intense pleasure could be called an "exorcism," she nonetheless finds herself craving the experience again.
