Bound at the wrists and ankles, the teen girl is completely at her Mistress's mercy. The Mistress, a stern woman with a cruel smile, feeds the teen a bottle, watching as the girl's face contorts with lust and shame. Once the bottle is empty, the Mistress orders the teen to remove it with her teeth, her voice cold and commanding. The teen complies, her lips wrapping around the bottle's neck, her tongue licking off the remnants of her own squirt. The Mistress watches, her eyes gleaming with satisfaction, ready to move on to the next humiliating task.
