In a POV femdom session, a powerful mistress focuses on her bisexual sub's ass, intent on making him beg for more. She starts with a small toy, easing it into his virgin hole, watching as he tenses then relaxes, accepting the intrusion. She smacks his ass, spurring him on, "That's it, take it like a good little slut." She increases the pace, fucking him harder, her dominance growing with each thrust. She switches to a larger toy, his moans echoing as she pushes it deep inside him.
