As the second girl, Amy, stepped into the room, her eyes widened in astonishment at the sight before her. Her schoolmate, Sarah, was straddling their scatologist, Professor Williams, his head buried deep between her thighs as she grunted and strained, voiding her bowels onto his upturned face. The pungent aroma of fresh feces filled the air, and Amy couldn't help but feel a rush of excitement course through her veins.
"Oh fuck yes!" she exclaimed, watching Sarah's turd drop onto the professor's head like a heavy weight. He groaned, his mouth foul with the taste of excrement, his hands gripping the desk forcefully as he tried to maintain his position. Sarah watched Amy approach with a wicked smirk.
"It's your turn now, slut," she said playfully, leaning down to whisper in her ear. "Show Mr. Williams just how much you love taking a load of shit in your mouth."
Amy stepped up to the desk, trembling with anticipation as Sarah moved out of the way. She couldn't believe how hard she was getting just from the thought of filling the professor's face with her filth. The smell alone was enough to make her clit throb uncontrollably.
"What are you waiting for?" Sarah giggled, slapping her ass cheeks. "Get to work!"
With shaking hands, Amy lifted up her short skirt and pulled down her panties. She positioned herself over the professor's face, feeling the warmth of his breath on her slick folds. As she began to grunt and push, she could feel the familiar heaviness in her gut, the urge to empty herself completely taking over. Soon, hot, lump after hot, lump pressed against the professor's eager lips, and he opened his mouth greedily, accepting every drop of her disgusting load.
The feeling of power surged through Amy as she emptied herself onto the professor's face. She groaned and shuddered, biting her lip to stifle the animalistic noises that threatened to escape. When she was finished, she stepped back, wiping the sweat from her brow with the back of her hand. The professor sat back slowly, wiping his mouth and chin with the back of his sleeve, his eyes glazed over with lust and disbelief.
"Wonderful," he whispered, his voice hoarse from the foul taste. "Absolutely wonderful."
The girls high-fived each other, their faces gleaming with satisfaction. They watched as the professor struggled to his feet, his pants and underwear in shreds, his hard cock erect and dripping with pre-cum. They circled him, admiring their handiwork, as he slowly lowered himself onto the desk once more.
"It's time to reward our little toilet slaves," Sarah said, grinning wickedly. She motioned for Amy to join her as they took turns straddling the professor's lap, grinding their bare pussies against his cock. The scent of shit and sweat mingled in the air, and the pleasure and humiliation on the professor's face was a sight they both savored.
Finally, he could take no more. With a powerful thrust, he buried himself deep inside Sarah's soiled pussy, groaning loudly as he began to fuck her. Amy leaned forward, pushing her soiled pussy against his face, grunting as she felt him tongue the remnants of her shit from his lips. They took turns riding him, their dirty pussies squeezing and clenching around his cock, their asses red and raw from the brutal pounding.
As their orgasms overtook them, the girls cried out in unison, their voices filling the room with the sounds of pleasure and depravity. The professor shot his load, covering their stomachs, chests, and faces with his thick, white cum. They collapsed against each other in a heap on the desk, panting heavily.
"That... was... incredible," the professor gasped, his chest heaving. He looked at them with newfound respect, his eyes sparkling with admiration for these two filthy girls who had brought him to the brink of insanity.
And so, their dark lesson continued, a cycle of depravity and pleasure that would leave them all addicted to the taboo thrill of scatalogy.
