[Cosken] I'm Being Bullied By My Sister's Bullies

A timid younger brother suddenly replaces his busty older sister as the fixation of the two dominant, big-breasted schoolgirls who used to torment her, turning their bullying into a possessive, teasing campaign centered entirely on the sole male. Torn between his soft, devoted sister and the overwhelming curves and confidence of her dark-skinned gyaru tormentors, he is pulled into private tutoring, whispered confessions, and increasingly intimate group play where fear melts into eager submission. What begins as intimidation becomes a jealous, affectionate rivalry for his attention, blurring protection, seduction, and sisterly loyalty into a dangerously addictive trap he does not want to escape.
