Rin, a diligent H-cup office worker, is about to experience the ultimate 3-hole reward. Her unexplored anus is prepped with balloon pumps until it's soft and dilated, while she endures deep-throat gags. The masochistic switch is flipped as she's subjected to fist dildos and an 85cm dildo twisting through her S-curve. Even as her consciousness fades from the 3-hole destruction, her body continues to react with insane climaxes. A total collapse of body and mind.
