She goes in dogged pursuit of your cum.

Amber lifts herself off your cock and settles down on her knees, then falls forward onto her hands and waves her ass in the air. “Come on, stud,” she says in a voice thick with passion. “Give me that big fucking pussy rocket. Take me hard—use me for your pleasure—fuck me into submission. Take my tight fucking college-girl pussy NOW.”

You get up on your knees behind her, line yourself up, and punch all the way in as hard as you can. She rocks back on her knees to meet you, and your hips meet her ass with an audible slap, echoed by the slap of your balls against her twat. You’re close to cumming, and clearly, so is Amber. You fuck her like a piledriver, hard and fast, sending her big tits swinging wildly and slapping against each other; she moans her approval and watches you in the mirror.
