A submissive should know his place. When a task is failed, when Mistress is disappointed, or just in the mood to exert a bit of OTK discipline - punishment is the only suitable outcome. This sub failed to meet my expectations. Laying over my knee, the palm of my hand connecting with the skin of their ass, again and again, until it's bright red and aching is a reminder they won't soon forget. If you enjoy sensual cruelty, degradation, humiliation and submissive training you will enjoy this.
