She don't say nothin'

Bexi looked up at him with heavily blinking doe eyes, but neglected to pull her mouth off Set's cock in order to pass a reply. She merely sucked harder, and started to moan around his cock. She reached out with both her hands and grabbed Set's bull balls, aggressively squeezing and manhandling them, coaxing out his cumload.
As she roughly massaged his ballsack, Set's massive sticky truncheon, now slid most of the way down her gullet, began to quiver and tremble, the head engorging and reddening deep inside her. He grabbed her unresisting head and began to fuck her face, slamming his weapon forcefully in and out of her abused, stretched throat. Each time half his veiny meat withdrew from her mouth, amazingly still eagerly sucking hard despite the ever increasing vigor of the facefuck, it would be glistening wet, completely covered as it was in sticky precum and saliva.
Either Bexi must have sensed the impending signs of an orgasm, or she was responding to the brutal pounding her normally small throat was taking, because her muffled noises of enjoyment around his shaft increased in both intensity and pitch, seeming to coincide perfectly with the building up his ejaculation, almost as if he had his own soundtrack.

At precisely the moment of truth, Bexi pulled herself off the shaft, watching with wide-eyed fascination as the fat, long trunk of a penis, sopping wet from its travels, pulled quickly out from her oesophagus, until only the thick, pulsing cockhead remained in her mouth, resting on her warm, awaiting tongue.
Set looked down at her upturned face, and the sight of her innocent peepers blinking seductively up at him, transfixing him just as she was patiently waiting for her huge cumload to taste, her big red lips wrapped around his head and her bulging little mouth filling up with saliva in her expectation, caused him to finally let loose the orgasm that had been building up ever since she had first hungrily sank her face down onto his cock.

Great streams and strands of cum shot out of him, washing into Bexi's mouth. She greedily drank down the thick, creamy mixture, swilling it around her mouth for a second with each load to savour the rich, novel taste. Her eyes, still determinedly locked with Set's, widened even further in disbelief as he continued to pump out jets of hot, pudgy cum, the consistency of syrup. She stopped swilling and concentrated on gulping it down, her larynx bobbing as she swallowed as fast as she could to stop her mouth overflowing.
"Take my massive cumload all in your hot mouth, you slutty teenage bitch." Set grunted, impressed with how much cum she managed to swallow in the time, with only about a couple of spoonfuls of the manmilk drooling out and down her chin, and collecting in the cleavage of her schoolshirt.

After a bit the flow peetered out, the remaining dollops of cum being sucked out by a red-faced, cum-lipped Bexi. She pulled her head back, and gave one final swallow.
"Oh my god, that was amazing!" She beamed, her bright eyes flashing and long strands of cum still dripping down from her mouth. "That has gotta be the best meal I've ever had! It was like salted creamy treacle! I'm so glad I'm your Zlutta!"
Set smiled. "Not yet you ain't... that was just the starter. I think I remember what I had to do to make you my Zlutta all official, you wanna have a go?"
Bexi giggled. "You bet I do! But on one condition!"
Set frowned. A condition? Did she not want it as much as he did? "Uh... like what?"
"Well, can I leave on my miniskirt?"
