GROS-011 Younger Sister Training – Mitsuka

Mitsuka, a top student and student council president at school, transforms into a submissive masochist once she returns home to her older brother. Stripped of her uniform, the honor student exposes her plump body and begs him to scold her more. Face-slapping during deep-throat oral, nose play, vibrator torment under restraint, choking, and cock training escalate step by step; each time she is soiled, her masochistic eyes grow wet. A hard training piece that follows the fall of a naive younger sister around the obscene secret shared by brother and sister.
