RBD-050 Electric Shock Training: 2 Schoolgirls and Other SM

Private investigator Ai Shibuki (Mizuki) infiltrates the interrogation facility disguised as a mountain villa where suspicious instructor Hayami is located, to investigate the disappearance of Rimi Matsushita. Ai attempts to go undercover as a journalist to extract information, but instead gets caught in the act and becomes the target of a sadistic interrogation. Despite her strong sense of justice, Ai can't resist the intense training and is eventually exposed to her latent desires, undergoing M-style awakening and erotic brainwashing.
