Keep her on her knees, but give her what she wants.

You pull her back by the hair, letting her catch her breath and wipe her mouth with the back of her hand. She stares up at you, eyes hazy and fogged with insane lust. She looks so good on her knees, degraded, pliable …

George lets out a long, eager sigh when you force her to all fours, then kneel behind her. She bites her lips when she feels you rub your slick cock between her hot, round ass cheeks, rocking back against you.

“Remember when you ground up against me in the elevator?” you whisper, leaning over her as the two of you roll and grind against each other in a moment of heated anticipation. “Ever since then, I always wanted to fuck your ass. You ever think about that?” She nods, still grinning. “Good. Then maybe you’ll be ready for how rough I’m going to buttfuck you.”

“Hurt me?” You start to answer when George interrupts your thought process by looking back at you. “No, like, James: hurt me.” She cocks her eyebrows as she speaks, pointedly pushing back extra hard, and you can’t resist her even when you’re on top. You lean back, then shove your cock all the way up her ass in one hard, smooth stroke.

George outright shrieks at that, then covers her mouth with one hand as you stay balls-deep in her ass. You start to move back and forth steadily, and a perverse moan slips out from between her fingers, a raw noise of agony and desire as you can feel her relaxing to get used to you sodomizing her. You grip her hips tightly as she works up the will to slide back on you, and her encouragement leads to you picking up your pace.

By the time you’re on a rhythm, George’s palms are both on the floor again as she grunts and groans, riding with your timing as you fuck her in the ass. There’s no sign of reluctance despite it hurting her, and she even laughs between another primal noise, a positively debauched little sound of enjoyment. Her enthusiasm makes it feels even better as you ram harder and rougher into this ass you’ve dreamed of defiling for years, both of you working on the other with unashamed passion as you vent out your frustrations with each other all over the floor of George’s bedroom.

She’s so nakedly happy to be getting her ass filled by you that you’re not even surprised when she cums from it, gasping and moaning as she squirts all over your balls and down her legs. Her tight ass clenches harder on you when she does, a needy, horny reflex demanding you to cum with her. You’re close, but manage to make her ride her first climax into a second, then a third as you pound her butt relentlessly. Her big, beautiful tits bounce underneath her shirt, nipples stiff and presenting through the fabric as her eyes roll back, absorbed by the intensity of orgasming from you absolutely punishing her asshole.
