Eishun Makio is a good-for-nothing teenager with overly perverted tendencies. Worried about his well-being, Eishun's mother assigns his childhood friend Kiriha Hariyama to take care of him. Wearing a maid uniform, the beautiful yet bossy Kiriha seizes all of his porn magazines, which makes him resort to masturbating while looking at her pictures. To his dismay, Eishun is caught in the act by Kiriha—however, she herself seems to have something lewd in mind.
