Sevengar] Anoko no Chikubi wa Kaihatsu Zumi [Complete]

Tsubaki, a demure schoolgirl with a mysterious aura, is recruited by a group of men who turn her into a public sex toy, subjecting her to relentless bondage and intense nipple stimulation. Her shy smile masks a conflicted yearning as she is forced to pose provocatively, her body exposed and her nipples pierced, while onlookers mock and film her humiliation. The story builds a tense, erotic atmosphere of power imbalance and forced pleasure, culminating in a climax where her cries of pleasure echo amid the crowd.
