Overview

His step-sister is an erotic manga artist. Reika usually relies on her step-brother, Yuu, for support while she works hard on her manga manuscripts, but once she finishes a manuscript, she can’t control her desires and transforms into a total slut! With her body aroused from drawing too many erotic scenes, she gives in to her instincts, unleashes her desires, and pounces on Yuu without hesitation! Today, just like every other day, she’s determined to milk him dry, shoving herself into every orifice she can find! There’s no resisting her step-sister’s relentless sexual assault…!
