Bound and vulnerable, the submissive is introduced to the art of being a human piggy bank. Mistress, her eyes gleaming with dominance, commands, "Open wide." The submissive complies, and she inserts a ball gag, ensuring silence. She then produces a riding crop, tracing it along their skin, creating a delicious mix of fear and excitement. With a flick of her wrist, she strikes, the crop leaving a satisfying mark. The submissive moans, their body squirming, as Mistress continues, turning them into her personal piggy bank, filling them with her power.
