Maki-chan to Now.

One night, a struggling light novelist and eroge writer catches his stunning neighbor, Maki, masturbating on her balcony. This elegant, intelligent beauty—caught in the act—doesn't flinch. Instead, she whispers seductively, ‘You’ve seen my depravity. Surely you’ll blackmail me? So go on, ravish me, break me, force me into every perverse act you desire.’ Beneath her poised demeanor lies a virginal nymphomaniac. And so, for reasons unknown, the protagonist agrees to date her. Their daily life becomes an endless, explicit journey of raw desire.
