4K Ultra HD Mia mounts her chastity slave’s face. He’s so weak and tiny! Mia bounces her ass and giggles. The slave struggles to breathe. Mia rocks her hips back and forth. She tells the slave to stop squirming. Mia changes her position so that the slave’s nose is in her crotch. She giggles. “No breathing for you!” Mia stretches out her legs. The slave’s face must bear her full weight. This is very challenging for the slave. He cannot breathe at all when she sits like this. She tells the slave to stop fighting her. She has already decided that he is not going to get air. The slave becomes very passive. He eventually fights less and less and becomes more accepting of the situation. Mia likes that he is starting to give up. That’s what this training is really about. The slave becomes less animated and more lifeless. Mia bounces her ass contentedly on his passive body.
