Fuck her ass.

You look down at her kneeling form and pull off your sweatpants. You walk around and kneel down behind her. She spreads her knees a little wider, having figured out what you're going to do, though probably not where you're going to do it. You stroke her reddened ass and flip up her skirt to get a good look at her charms. Her pink pussy lips peek out at you from under her heart-shaped ass, but right now you focus on the tight little hole of her ass. You briefly consider getting some lubrication, but decide she doesn't really deserve it.

For some reason, you've always had a thing about anal sex and you find the idea of finally trying it very exciting. You put one hand on each of her bright red and striped buttocks and spread her cheeks to expose her anus. She grunts a bit through the gag in surprise and you smack her ass in response.

You slowly ease your dick into the tight ring of her anus and push it in past her sphincter. You're able to push in rather easily, from which you surmise that she's rather used to taking it up the ass. Even so, the sensation of tightness that you feel around your dick is indescribable and quite thrilling. She applauds your dominance with little grunts of pain.

You get into a steady rhythm and Rosalind's grunts and groans transform into moans and sighs. Her tightness overwhelms you in very short order and you fuck her as hard and deeply as you can for several strokes, your balls slapping against her pussy, before spending your seed into her bowels. You are surprised by the number of spasms you have as you ejaculate into Rosalind's ass.

You stand up and take a good look at her gaping anus as it slowly closes back into shape. Now that you've gotten your rocks off, you're no longer as interested in dominating her. You search through the bag and find the key to the handcuffs and release her. You remove her gag and she takes a deep breath in response. Her face is still stained with tears from the ordeal you've put her through. "All right, Rosalind," you say, "You're dismissed."

She looks up at you and sniffles. "So all is forgiven?"

"If you continue to obey me, it will be," you respond.

She smiles and crawls over to you, surprising you by taking your dick into her mouth and cleaning it off. Then, she stands up, pulling down her skirt as she does so and wincing in pain. "That's good enough for me. Thank you, Parker." She kisses you on the cheek and walks out, a little gingerly from the ass fucking you gave her, leaving her toys behind.
