Fuck her ass of course

It's not every day you find a girl so willing and eager to take it up the ass, so you don't plan on wasting this opportunity. Taking the decision away from her, you toss her off your body and onto her back. Climbing to your feet, you stand near the bed and grab Zoe by the legs, pulling her towards you until her ass is nearly falling off the edge of the bed. Bending her in half, you lean forward, bringing your face inches from her ass, and spit on her puckered brown hole, making her a tad more slick for what she's about to receive. Grabbing her ankles, you lift her legs up, making her feet point up straight in the air, then line the head of your cock up with her fully exposed bottom. Zoe helps, grabbing behind her legs with one hand, and spreading her ass cheeks apart with the other. Already primed from your fingering, her ass gapes opens up for you, letting your well lubed head slip past the first barrier and causing her to gasp in surprise.

"Oh David!" she squeals before biting down on her bottom lip. "Fuck you're big! Oooh, I want this so bad! C'mon big boy! Sodomize me! Split my tiny little asshole apart!"

You didn't think it was possible, but her dirty talk has just gotten you even more hard than you already were and a primal urge courses through your veins. With another push of your hips, you nudge yourself farther inside until you're more than two-thirds inside her. You withdraw partway before slipping back in, letting the combination of her own cum and your spit lube up her insides. It doesn't take long to accomplish this task, and you're soon working yourself in and out of her ass, the tighter fit making it all the more pleasurable. Your grunts, and her cries, fill the air as you begin to pick up your pace pushing in and out of her little poop-shoot. Looking down, you see Zoe's mouth agape, unable to talk, her eyes rolled into the back of her head, and her hard nipples pointing straight into the air. The muscles of her arms and her abs are taut as she braces herself against your anal ****.

In your enthusiasm, you start to lose your grip on her ankle and decide to just let one leg fall while firming your hold on the other, pulling it against your chest with both of your arms. Zoe is quick to adapt to the change, grabbing underneath her free leg to support it while spreading her legs wide for you and giving you the bonus view of her recently fucked, stretched out pussy.

The slight change in position must be a little easier for her to handle, because she's suddenly able to start talking again, begging for you to fuck her ass. "Ooooh, that's it David! Fuck my little ass! Pound me with that big fuck stick! Holy shit, I've already cum two more times with that thing in my ass and I'm going to cum agaaaaiiiiinnnn!" she calls out as she trails off into a wordless scream, body convulsing under you.

The extra pressure from her ass, along with her dirty talk and the site of her cumming beneath you, rapidly has you nearing the brink yourself and you know you won't be able to hold out much longer. "Fuck Zoe, I'm close too! I'm gonna cum soon!" you warn her while giving her the opportunity to tell you where to shoot it.

"Oh fuck, yes! Cum for me David! Cum for me!" she screams out in encouragement, letting you be the one to offer where you're going to empty your load.
