(Mc, futa) of course he does, the real fun is just beginning!

Bill saw Dr Schmidt walking towards the two of them, came an idea of how to get back at them. He quickly opened the book and added a single line to both of their pages.

“She has a hair trigger, and can cum from simply being visually stimulated by a woman’s body.”

Boom. The Tome closed. “Version 300” now stamped on the cover.

"Now, Jessica," Dr. Schmidt purred, sauntering up to the squirming futanari's desk with an exaggerated sway of his hips. "Which types of tectonic plates tend to have the most movement?"

Bill nearly lost it as he watched Jessica's massive cock visibly throb beneath the table, a drop of precum running down her length as she struggled to form a coherent response.

"Uhh... I think it's... Breastructive plates?" Jessica stammered, her gaze flickering desperately between Dr. Schmidt's fuck-me pout and the shapely thighs clearly visible beneath his painted-on skirt.

Dr. Schmidt frowned and shook his head, sending his brunette hair bouncing around his flawless face. "No, Jessica, that's not quite right," he sighed, putting a perfectly-manicured hand on his hip. "The correct answer is 'destructive' plates. I'd expect you to know that, given how much time we've spent on this unit."

As Dr. Schmidt turned away with a disappointed huff, Bill had to stuff his fist in his mouth to keep from cackling like a hyena. The professor was completely oblivious to the effect his slutty mannerisms were having on the class, chalking up Jessica's brain-fart to simple collegiate flightiness. If only he knew the real reason his students were always stammering and misspeaking around him!

But the real show was just beginning. As Dr. Schmidt bent over once again to retrieve his pencil (Bill was starting to suspect he was doing it on purpose), his already-scandalous skirt rode up to fully expose his ass and panties to the class. And unfortunately for Jessica, his glistening slit was mere inches from her face, close enough that she could probably smell it.

The result was instantaneous and explosive. Jessica's eyes rolled back in her head as she let out a choked moan, her hips bucking uncontrollably as her massive cock erupted into the bottom of the table. Bill watched in awe as a geyser of thick, milky futa-spunk jetted from the front of her skirt, splattering under her desk and chair in a lewd display of spontaneous orgasm.

Beside her, Beth had been forcing herself to look away from her professor. When she heard the noise she jerked her and looked on in shock. Her hand flying to her own throbbing erection as she tried to process what was happening. "Jess, what the fuck?!" she hissed, her eyes wide with disbelief. "Did you just... cum!?!”

Jessica, still shuddering through the aftershocks of her climax, could only nod weakly and point a trembling finger at Dr. Schmidt's exposed ass. Beth followed her gaze and instantly understood, her own cock pulsing and twitching as she drank in the sight of the professor's glistening folds.

But understanding quickly gave way to overwhelming arousal, and before Beth could even think to stop herself, she was cumming too. Her skirt tented obscenely as her massive cock spasmed and jerked, pumping load after load of hot, sticky jizz into her already-soaked panties. She let out a guttural groan as she painted the underside of their table with spunk, her hips thrusting involuntarily as she rode out the most intense orgasm of her life.

By the time Dr. Schmidt finally straightened up and turned around, Jessica and Beth were both slumped over their desks in post-orgasmic bliss, their skirts drenched with cum. The professor seemed not to notice, however, blithely continuing his lecture as if nothing out of the ordinary had happened.

But Bill noticed. And he couldn't resist the opportunity to twist the knife a little.

"Damn, Jessica, Beth," he called out loudly, drawing the attention of the entire class. "Looks like you two need to invest in some thicker skirts! I don't think those flimsy little things are gonna cut it!”

The room erupted into laughter and jeers as Jessica and Beth's faces burned with post-cum humiliation, their cheeks flushing an even deeper shade of red. They squirmed in their seats and tried to cover up, but it was far too late. The damage was done, and now the whole class knew what thirsty, hair-trigger futas they really were.

As the laughter died down and Dr. Schmidt droned on, Bill sat back in his seat with a satisfied smirk. He couldn't have planned it better himself - Jessica and Beth had gotten their just desserts for gossiping about him, and he'd even managed to further normalize futa cum-accidents in the process! All in all, a very productive use of the tome's reality-warping powers.

But Bill was far from done with his sexy scheming. If anything, the events of today's class had only whetted his appetite for more futa-filled debauchery. He couldn't wait to see what other filthy fun he could have with this newly-cocked campus...
