[InfernalRestraints] Obedience - Lydia Black (12.21.2018) 720p

London River, an experienced trainer, struggles to manage a particularly difficult subject named Lydia. Seeking assistance, River decides to consult a friend for advice. The initial approach focuses on establishing dominance, which includes strict measures such as enforcing silence and using a heavy collar.

The trainer emphasizes the distinction between vanity and obedience, explaining that true obedience stems from selflessness. The goal is to diminish the subject's sense of importance to facilitate the emergence of obedience. To achieve this, the training involves making the subject feel unattractive. Once the subject acknowledges its status as property, the training shifts to a more intense phase, where the subject learns to associate pain with obedience. The objective is to condition the subject for the trainer's pleasure.

The narrative includes various explicit adult themes and activities such as the use of vibrators, caning, electric shock, strap-on sex, choking, and role-play.
