[Shine Nabyss] Zu-senpai to Ogino | Ogino and the Predatory Lesbians

Ogino, a junior, is drawn into a secret after-hours practice session with a group of senior girls, where their supposedly rigorous training becomes a coercive yuri ritual of restraint, bondage, sex toys, and painfully sensitive breast play. Her shy gratitude in the opening spread gives way to panicked protests as the girls restrain her, praise her responsiveness, and keep escalating through aphrodisiacs, nipple stimulation, and prolonged aftercare. The blue monochrome pages, dense overlapping bodies, and contrast between eager coaching and Ogino’s frightened reactions make the power imbalance the story’s sharp, unsettling hook.
