[Sena Youtarou] Perverted Onei-chan Ch. 1-8

An older sister's insatiable hunger for her younger brother turns into a twisted, livestreamed spectacle as viewers cheer her on, her glasses slipping down her face while she begs to be filled to the brim. The perversion escalates when a shadowy demon girl with wild horns joins the fun, declaring the boy isn't satisfied until he's been thoroughly claimed. The final pages reveal a chilling turn: an older man on the phone has discovered their broadcast and plans to broker a high-price sale of the exhausted brother to other wealthy connoisseurs, setting the stage for a devastating auction of innocence.
