Kneeling before her mistress, the sub awaits her command, eyes downcast, body trembling with anticipation. The mistress, clad in black leather, snaps her fingers, and the sub responds, presenting her ass and pussy for inspection. The mistress runs a gloved hand over the sub's wetness, a cruel smile playing on her lips. She orders the sub to keep her eyes closed, then buries her face in the sub's pussy, licking and sucking with a fervor that belies her usually stern demeanor. The sub moans, her body writhing, as the mistress brings her to the brink of orgasm, only to pull back, teasing her mercilessly.
