Green Eyes: Ane Kyun! yori The Animation

Synopsis

Makabe Aizawa is a stunning woman, flawless in every field and exceptionally striking since childhood. Behind her outwardly sweet demeanor, however, she behaves cruelly toward her younger brother Haruto, ruling over him like a queen and making him serve as her butler each day. Recently, her conduct toward him has changed—she requests kisses and even causes him to ejaculate. It appears that Aizawa harbors a desire to go beyond the boundaries of a sisterly relationship.
