[TSF Mousou Chikusekijo (Kuratsuka Riko)] Furyou in Kanojo ~Boku no Kanojo no Karada wa Furyou Otoko (Aitsu) ni Nottoraremashita ~ [desudesu]

When his sweet girlfriend Ruri starts lounging with her legs spread and flashing a lazy, cocky grin, bespectacled Eiichi realizes something is very wrong—a vanished delinquent boy has taken over her curvy body, and she wastes no time popping her shirt open and daring him to touch what used to be his girlfriend alone. Desperate to expose the impostor, he quizzes her on picnics, home-cooked meals, and kisses, only to have every intimate memory answered with teasing confidence and a wink. But when a blonde delinquent girl struts through the halls calling him 'Eiichi-kun' and promising to meet after school, it's clear this possession game is far from over.
