[Kuragari] Chikubi iki gaman ge-mu o kyōseisareru Sui-chan (Hoshimachi Susei) [Full Color]

Hoshimachi Suisei walks into what should be a routine meeting about a private concert, only to wake up drugged, stripped bare, and bound at the mercy of strange men who turn her big breasts into their helpless plaything. Forced into a cruel nipple endurance game, she fights to hold back her voice as relentless fingers and medicine-soaked brushes push her toward the edge, her idol pride crumbling with every shuddering moan that escapes her. When she finally loses control on camera, her captors seal the victory with a humiliating bukkake and a blackmail threat guaranteeing she'll be called back.
