[Turn Casey into an absolute cumslut]

"Yes! Thanks. I mean... I'm glad that you agree with me." Casey's eyes fill up with the sight of her target after receiving her imaginary friends approval and, without hesitating, she lunges onto the shaft with gusto, impaling her throat with it's impressive length.

"Mmmmm..." Casey hums in satisfaction as she pulls back, running her outstretched tongue under the length of the shaft all the way back to the glistening tip.
Casey's eyes widen as she gets her first taste of precum. It's indescribable. It's the best thing she's ever tasted! And, like a junkie whose just had their first hit, she's hooked.
"More!" Casey moans shamelessly, unconcerned if her imaginary friend Imaginary friend's name hears her, trying to coax more precious nectar from the tip of the cock with flicks of her tongue and undulating throat.

Casey's lips create a tight seal around the shaft of the cock as she bobs her head back and forward earnestly, attempting every trick that she has ever seen during her illustrious porn watching career.

Sounds of **** fill the room as Casey slips the cock in and out of her throat, trying her utmost to suppress any gag reflex. A steady stream of drool bounces off of her chin and pools on the ground below.

After what doesn't seem like very long, but was actually close to 20 minutes, Casey feels a pulse in her throat, followed by another, and another. Not wanting to miss out on the load she worked so hard for, Casey inches back so that she's nursing the head of the cock instead, filling her mouth, and bulging her cheeks, with more of that delectable cream.
The ejaculate was thicker and more flavorsome than than the precum and Casey couldn't help but gargle it around in her mouth before swallowing down her gullet.

"Mmmmm..." Casey utters drunk with cum, one hand fondly rubbing at her belly while the other absent mindedly rubs herself over her drenched jeans. She's utterly blissed out after such a satisfying meal.
