[Makin] Jūdō o Narau | Leaning Judo

A younger brother endures a humiliating judo lesson from his older sister, who taunts him about his size while the family’s twisted rules bind them together. She commands him to obey, promising to transform him into a submissive girl with exaggerated features as another sibling watches and vows to keep a close eye on his compliance. The tension rises toward an inevitable, painful climax as his resistance crumbles under her relentless control.
