The femdom mistress welcomes her trainee, a sniveling wimp, into her realm of pain and pleasure. She orders him to strip, exposing his tiny balls, which she promptly inspects, sneering at their pitiful size. She begins his training, using her sharp heels to crush his balls, making him yelp like a puppy. She spits on him, calling him a worthless worm, as she continues her relentless assault. He tries to please her, begging for more, but she just laughs, knowing she's only just beginning to break him in. She promises him a world of pain and humiliation, and he eagerly accepts, his cock hardening despite the agony.
