Let's start off with her on top

With that statement, she straddles you, grinding her pussy against your dick and letting the shaft spread her labia apart. "Mmmmm David. I can't wait to feel this big.... Hard.... Cock.... Inside me. Stretching me out... Making me cum... Is that what you want too?" she asks, sliding her slick pussy along the length of your dick.

"Fuck Zoe! You know I want it! Stop teasing me!" you plead.

Apparently, Zoe isn't interested in teasing you very long, because right then she grabs hold of your dick, places the head against her opening, and sinks herself onto your member. Your lubed cock slips easily between her wet folds and you're soon engulfed by her muscled walls. She pulls your head to her chest and lets out a low purr as you sink deeper inside, then wiggles her hips to allow the rest of your length to penetrate her.

"Oooooh, David. Your cock is soo big!" she moans out. "It fills my pussy sooo good!" she tells you as she begins grinding her hips into you. Her natural juices have already started flowing and completely coated you, allowing you to slip easily in and out of her slick tunnel. "Mmmm... oh yeah... oooh, that's nice." she coos in your ear, as she sets the pace. Her movements start slow; taking your entire length to the hilt before carefully unsheathing you, going just to the point where you're about to pop out, then reversing and starting to process over again. As she grows accustomed to your size, her pace increases; not bothering to withdraw quite as far and bucking her hips harder into you with each thrust down. She grunts out loud and her pussy constricts around you with each of her downward movements, intensifying your pleasure.

Sliding your hands to her hips, you start matching her rhythm and pushing yourself deeper inside her, the head of your cock now bottoming out each time. Just as you start to think she's going to start moving faster, Zoe stops with you fully inside her and looks you in the eyes. "Oh god David, you feel so good, but I need more. I want both my holes filled. I want you to put your finger in my ass. Would you do that for me? Will you finger my ass while you fuck me with your big, hard cock?" she asks you, grinding her pussy in to you.

Truthfully, you've always had a bit of an anal fetish and are thrilled with the request. Without saying a word, you move one of your hands from her hips and trace your fingers around her pussy, lubing your fingers up with her juices, then place the tip of your middle finger against her puckered arse. Zoe is obviously used to taking things up her ass, because a little nudge is all it takes for your finger to pop in to your first knuckle.

After only a slight, reflexive contraction, her sphincter quickly relaxes, allowing you to sink your finger farther inside as you simultaneously push your cock deeper in her pussy. "Ooohh, there you go. Just like that." she coos in your ear. "Oh fuck, I love having both my holes filled." she tells you as she begins sliding her slick tunnel up and down your length once again, gradually picking up her speed and getting more and more into the double penetration she's receiving. "That's it, finger fuck my ass while you pound my pussy with your hard cock!" she yells out, throwing her head back in ecstasy. "Oh yeah! Oh yeah!" she continues. "Hard like that! Fuck, it feels so good! Oh shit! Don't stop! Harder! Harder! Fuck! Fuuuucccckkkk!" she screams out as her body begins spasming on you.

No longer able to control her own movements, you take the initiative to continue the **** on both her holes, thrusting your hips up into her while diddling her ass from inside. Your forearm burns as you curl your finger downward towards your cock, sliding in and out of her tight, bung hole, in sync with the movements of your hips, focusing on trying to draw out her orgasm as long as possible. When her body finally falls limp on top of you, you're able to withdraw your, now cramping, finger from her ass and slow the pace of your hips, allowing you to catch your breath and give your arm a well needed rest.

Zoe's face was buried in the pillow next to your head, but as she recovers, you feel her turn towards you, her breath warming your ear. "Oh my god David, that was sooo gooood!" she says, still somewhat short of breath. "I can't remember the last time someone made me cum like that, and you're not even done yet! You've got me sooo horny!" she says in frustration, grinding her pussy into you once again. "My god, I want to keep fucking you, but I want to feel you in my ass too! I don't know what we should do!"

It looks like you're being presented with a win-win situation. After making her cum, this cock-hungry slut is primed and ready for you to do anything you want to her, all you need to do is make the decision.
