Beautiful photoshoot model Iori Furukawa is being treated as a sexual service pet for otaku fans, doing whatever they like to her! She is advised that to become popular, she should engage in more naughty activities, and out of desperation, she gradually becomes obedient to the perverted otaku. Eventually, her hidden masochistic tendencies bloom, and in the end, she transforms into an M pet, happily serving while covered in used condoms filled with the otaku's semen.
