A beautiful girl named Shiina Sora, dreaming of becoming a musician, sings on the street. She is deceived and taken in by a man claiming to be a scout... restrained by cold, inorganic iron pipes and deprived of all freedom. "Please, stop it inside!!" A beastly penis pierces her defenseless, slender body, and a thick stream of semen is injected... her cheeky mouth can no longer speak, and the girl's body, unable to resist any longer, becomes a slave to the men's desires.
