A power dynamic shifts as a submissive learns the art of cum-eating under the watchful eye of their dominant mistress. With a stern look and commanding tone, she instructs her slave to stroke their cock until they're on the brink of orgasm. As their body tenses, the mistress orders them to stop, demanding they taste their own pre-cum. The submissive, eager to please, follows her commands, their face contorting in a mix of humiliation and pleasure.
