When she woke up, her body was completely restrained by iron devices. Her name is Umi, a beautiful girl who dreamed of becoming a model. She had come for an audition at a talent agency, but when she regained consciousness, she found herself in this condition. The drink she was given during the interview had been spiked with sleeping drugs. The agency was secretly running an illegal operation, training lesbian pets for wealthy clients. Forced to ingest aphrodisiacs, she was tormented with electric vibrators and subjected to guillotine restraints and double-headed dildos. A lesbian threesome erupted into wild orgies, with one training session after another assaulting her. Soaked in aphrodisiacs, her body became one that could only desire women, transforming her completely into a sex slave.
