Reika is a talented but perverted erotic manga artist who lives with her step-brother Yuu. She depends on him for daily support while grinding through her deadlines. However, once she finishes a manuscript, the constant drawing of lewd scenes leaves her extremely aroused. She then undergoes a dramatic personality shift — transforming into a hypersexual slut who aggressively pounces on Yuu. In Episode 1, right after completing her work, Reika’s pent-up desires explode. She throws herself at her step-brother, demanding intense sex and pushing him to “make her eyes turn into heart marks” with overwhelming pleasure, using every part of her body (mouth, breasts, pussy, etc.) to milk him
