For a professor of history, she'll try the oldest trick in the book

So it had come to this... Doubles didn't find the crabby old professor attractive in the least, but she'd have to put aside that opinion for a while in the service of the ancient art of seduction. He may be big, but she wasn't scared... all she had to do was make him spend his limited old-man stamina and he'd probably go home to change! Or perhaps the doppelganger was going to end up putting Clara in a prolonged, sordid relationship with an older man at the college, whereby the high priestess dresses in a schoolgirl fetish uniform and meets the guy in an abandoned classroom for lewd engagements.

No time to worry about that! Let Geod sort 'em out, as they say.

While Postucles was busily writing up lecture notes in chalk upon a giant blackboard at the back of a woefully underutilized college theater, Doubles shimmied her way from the front desk she'd originally seated herself at, swaying Clara's curvaceous hips this way and that while fluttering Clara's long eyelashes. The moment he looked over, he'd get an irresistible eye-full!

... He was taking a while to look over. By the time Clara finished that slow, catwalk strut, it proved nothing but wasted effort. She ended up standing right behind him, without a single reaction so far. Puffing up her cheeks and pouting, the girl grabbed her professor by the shoulders and shook him in a scene out of some slapstick jester's play, causing his bald head to bob back and forth.

"Miss Doobie! You've just ruined my perfect block lettering!" The history buff threw down his chalk and turned, his round, bald head glowing red like a tomato... Unfortunately, it had nothing to do with embarrassment or arousal. His only emotion was rage at being interrupted.

The high priestess lookalike batted her eyelashes again, then put on a small, curving smile. "Oh, no! You dropped your chalk, Mister Posturing. Let me just... kneel down and pick it up for you..." The girl got down on her knees in a squat, allowing her bottom to sit near the backs of her heels and staring up at her professor with big, blue eyes. She picked up the chalk, then made a sexy show of running her hot, pink tongue along its length... then spit into the open air, sending chalk-dust everywhere. "Blech! I-Isn't that something sexy schoolgirls normally do in pornography?! Licking the writing thingy?!"

"Ah, you're thinking of a pen or quill. Chalk will just get dust in your throat, plus, it's just been on the floor. Very unsanitary, Miss Doobie." Postucles shook his head sympathetically and crossed his arms.

The doppelganger's pout intensified for a moment, then immediately replaced itself with another sexy grin; she eyed the lower part of Postucles' robe, as she was now about head-height with his groin. "I think I know something every more unsanitary... it's me sucking your smelly, old dick~"

"... It's also kind of a myth that upstanding elder gentlemen such as myself like to hear about how stinky and aged our penises are."

"Oh! Sorry!" Doubles bowed her head a few times and pressed her hands together in an expression of begging forgiveness. This seduction didn't seem to be going overly well. "W-Well, I'll still suck it, stinky and old or not! Lift up your robe!"

"Now see here, Miss Doobie! Like I said, I've been around the block a few times and I know when a student is trying to seduce me to skip out on my history lessons!" The professor stomped his boots upon the floor in aggravation, raising more chalk dust.

Doubles reflected on how **** the average student must be to avoid this scenario, if they would resort to the same tactic she was using now...

Postucles continued to rant. "No deal! You're going to take your every drop of my lessons and swallow them down that pretty throat of yours, then you're going to lick it off of the tip and beg me to pour another serving of the hot, tasty stuff into your belly!"

"... W-Wait, are we talking about lessons or fellatio right now?"

"History lessons, obviously!!"

The doppelganger was becoming so confused, she wondered how anyone made it through college successfully... Were all professors as nutty as this guy was? "Professor Penischeese-"

"I-I told you that elder gentlemen such as ourselves are sensitive about young girls teasing the quality of their penises-!"

"Whatever! You may have been seduced by a girl or two, but I'm going to show you that nobody seduces a weird old man like Doubl- I mean, Clar- I mean, Doobie!" The doppelganger, proceeded to hike up the professor's robe and stick herself beneath, as though she was trying to act the role of a bed-sheet ghost. She found the man's trousers, expertly whipped off his belt, then pantsed him... while he continued protesting, she fixed his dick out from his ridiculously unfashionable map-printed boxers. It was... actually pretty impressive! She supposed she should have expected as much, given the guy's huge body and his vigor. Doubles was starting to understand that the professor might not be so old after all... his attitude made him seem about 10 or 20 years older than he really was. "I can work with this~"

"Do not! Do not work with it! You can't answer my trivia questions with your mouth full, young lady! Yiiiipe!"

The doppelganger had begun sucking mercilessly; he couldn't see her head, but the outline of it, billowing his robe out in front of his lap, was bobbing back and forth with the experienced motions of a young lady who likes doing this sort of thing. "Mwehehe... How'f fit f'mf'm?" She seemed to be the one asking the questions now, but unfortunately, he wasn't wrong: there was really no way to understand her with her mouth full of his dick.

"You're racking up extra detention! Get out of there this instant! Get out before I- uwoooooh!"

Truth be told, Doubles wasn't having such a bad time, but she did hope he'd go ahead and uwoooooh sooner rather than later so she could focus on her mission once again. The girl brutally stroked her tongue along the length of the professor's shaft, fondling his balls with one hand and steadying herself upon the floor with another. It seemed even this dyed-in-the-wool history fanatic could be made putty in the hands of a vivacious blond high priestess / college student with nothing to lose! Doubles might accomplish her goal of making the guy flee his own lecture after all!

... It seemed that way, however, interruptions have a way of coming at the worst times...
