You're almost there.

You feel her tremble before a squirt of pussy juices spray all over your balls as they slap into her, splattering her cum all over the insides of her legs. As she orgasms, her ass clamps down tight around your cock, squeezing so tightly it's as if her ass is trying to suck your shaft as deep inside of her as it can. As she cums, you stop thrusting for a moment and lean all of your weight forward, burying your cock as deep inside of her as you possibly can. You enjoy the sensation of her ass contracting around your cock, and once her climax subsides, you flip her over onto her back so she's facing you.

You look down on her soaking wet pussy, and the thought occurs to you to fuck her right now, but you can't show her any weakness. You're here to take her ass, just like she asked. You grab the bottle of lube and slide the tip into her squirting some more inside of her. You spread her legs wide, then reach around her waist and pull her back onto you. You pound away, and soon your cock begins to twitch... then throb... then pulse... and just as the flood gates open you pull her in as far as you can plunge your cock as deep as possible with all of your might.

As you empty a massive load into her bowels, her body tenses up with another orgasm while she flicks away at her wet clit. Her entire body tenses up, milking your cock as she wraps her legs around your waist and locks you tight up against her. You groan as she squeezes every single last drop of cum into her tight little hole before you collapse on top of her, your hardened cock still buried inside of her. When you've finally regained your composure, you slowly pull out, your cock still hard and covered in fluids. Gemma lies back on the bed, staring at the ceiling, and you watch as a thick stream of cum and lube oozes out of her gaping asshole.
