In this intense power dynamic, a confident woman commands her submissive partner to maintain his face buried in her ass for as long as she desires. She grinds her cheeks against his mouth, smothering him in her scent, while he struggles to breathe. His tongue darts out, tentatively exploring her forbidden hole, eliciting moans of pleasure from his dominant partner. She encourages him, "Longer, slave. Prove your devotion." His endurance is tested, but his desire to please her keeps him desperate for more.
