All the diagrams and charts in the world weren't going to capture the class's attention half as well as the sight of their teacher standing naked at the head of the class beside an Aerodactyl with his cock out. And on some level, Roxanne knew that, not even bothering with the more dry theory elements of this lesson as she jumped right into the practical demonstration. "As you can see, even at five feet and eleven inches tall, Aerodactyl penises are proportionately larger than any of the previous Pokemon we have covered in this unit." A unit about taking care of the sexual needs of rock type Pokemon. Roxanne never thought she would be so lucky as to be able to get paid to teach this.

As she spoke, she ran her hand along the throbbing, warm cock of the Aerodactyl standing there and letting the students stare at his endowment. It was her own personal Aerodactyl, one that she was very 'familiar' with, and the hand brushing along his cock made him groan and stretch out his wings a little bit as he readied himself for what was to come. An approving roar sounded out as he held himself in place and looked around the room. Roxanne's class room was packed in tight, this special summer unit having ended up overbooked and with a long waiting list from students all eager to both learn about the sexual treatment of rock types, and to see Roxanne's 'demonstrations'.

"Are you all taking notes?" she asked, running her hand steadily along the cock as she guided it about, trying to make sure that the class could all see it as she kept her grip firm and her strokes adoring. "Remember, there is going to be a test on this at the end of the unit." She bit her lip, trying to pretend she was thinking about the test at all as she drifted her gaze back toward the cock, toward her Pokemon's rock hard erection just begging for her touch. It was hard to focus when she was giving a 'lesson' like this, but given the lack of complaints, she didn't worry too much about that. Standing there completely naked, she felt the eyes on her, and the exhibitionistic thrill kept her very well distracted.

Easing down to her knees steadily, the whole class could see their teacher getting worked up all her own, and nobody said anything or interrupted with questions as they watched her go. It was quite the delight to behold, made all the better by the fact that with all eyes directly at the front, save for Roxanne's which were on her Aerodactyl's dick, nobody was going to worry too much about the way that hands slid down underneath the table, as almost nobody actually bothered to take notes about what was happening in front of them. How could they be expected to take notes under these circumstances?

Knelt down in front of her Pokemon, Roxanne was ready to take it further, licking her lips as she looked toward the class again. "Okay, now we're going to get into getting the Pokemon ready for this. Now, does anyone know why oral sex is especially good foreplay with a Pokemon as hung as my Aerodactyl is?' She looked around for a hand to come up, and it took a little bit longer than she would have liked, but she didn't say anything about why hands seemed to have disappeared as she called on the first hand she saw go up. "Jenny."

"To get the penis lubricated with saliva, but also so that you're more aroused and wetter, to help ease penetration," said the bookish girl up in the front row, blushing as she spoke in clinical enough terms that she didn't feel completely embarrassed by what she was saying.

"Excellent, Jenny, thank you. Yes, the primary purpose behind using oral sex as foreplay in this way is to guarantee that your pussy is absolutely soaked, because what can be a bigger turn-on than sucking a bit dick like this?" Her cheeks reddened a little bit too as she realized just how vulgar she was getting, eyes nervously drifting from the cock. She needed to keep more composed than this in front of her students. "Boys, you should take note of this too. For female Pokemon smaller than you, oral sex is just as mutually beneficial. And it's always good to repay the favour, and will help both of you out greatly in the arousal of the female partner. Aerodactyl and I won't be demonstrating that part here, but it is always a good thing to keep in mind."

Shifting herself and her Pokemon so that the entire class got a side view of their teacher down on her knees in front of the flying rock type's proudly presented cock, Roxanne took a deep breath, remembering that she had a class in front of her and not to get too deep into her own arousal and frustrations as she leaned forward and took the dick into her mouth. Immediately, the hunger hit her, the pang of desire that made her moan around the head of the shaft. Her lips tightened around the shaft, her eyes slowly closing as her attempt to keep herself together almost immediately began to shake and bubble in frustration. Having sex in front of her students hadn't really become easier as she found herself burning with an increasingly powerful exhibitionism kink, something about her hungers that simply could not be tamed.

Gripping the base of the long, meaty cock firmly, she was able to keep it still even as her head moved quickly. She wasn't going to show any patience or slowness as she got down to business, her legs pressed tightly together. As she felt the warm cock pressing down against her tongue, she could also feel her students' gaze upon her, making her wriggle happily about as she started to suck the cock down, eagerly fellating her Pokemon and letting the pleasure all takes it course. Her pussy quivered and dripped all over her thighs, a sign of just how hot and turned on she was.

As far as her students were concerned, Roxanne was liking the chance to fuck in front of them a little too much. As much as she may have tried to keep things clinical and cold, she seemed so excited to be on her knees and squirming as she slurped her Aerodactyl's cock down. But nobody minded that too much as they all nervously kept their gaze forward, almost all the boys having their cocks out underneath the table, slowly stroking and trying to be subtle about it as they watched the beautiful, black haired teacher go. Most of the girls were in the same boat, hand stuffed down shorts and up skirts, most of them using their fingers but one of them clutching a bundle of a couple pens from her pencil case that she held together to form a makeshift sex toy thick enough to fill her up a little better, working the improvised dildo back and forth as she beheld the beautiful sight, wishing she was there on her knees and helping Roxanne out.

Back and forth the gym leader's head bobbed, the thick cock pressing further into her mouth. The hand not holding tightly onto the base squeezed the leg of her faithful, helpful Aerodactyl as she did her best to keep it from slipping between her legs instead. The temptation to was incredible, her body aching and burning with need as she sucked happily on the cock, pushed further into a state of absolute bliss and need tat knew no end. But she had to keep it going, had to hold back and avoid the temptation for the sake of her lesson.

Or, as she actually did, decide to forget about the blowjob altogether. It was a waste of time, a red herring keeping her from the real fun. "Okay," she said, pulling back, an immodest number of drool strands connecting her lips to the fossil Pokemon's throbbing cock as she looked over toward the class just in time for them to snap under their own weight and run down to her breasts. "Once the foreplay has run its course, it is time to move on to the intercourse proper." She moved up to her feet perhaps too excitedly, shuddering as she grabbed hold of her desk and bent slowly forward over it, staring out now onto all the eyes watching her, seeing her naked as she bent forward and presented.

Aerodactyl admired the firmly taut backside of his professorial trainer as she bent over the desk, showing herself off excitedly to the Pokemon, wearing nothing but the bow in her hair. With a low growl the Pokemon got into position, guiding his cock toward her slick hole and pushing forward as he looked out onto the class as well, not caring much about the semi-public nature of the way he was about to rut his own trainer. He just focused on the task at hand, pushing forward and claiming the teacher with a single push.

"Nngh, yes!" Roxanne yelled, the exact opposite of what she should have done as she felt the cock slam into her needy twat. A jolt of pure delight surged through her as she felt the electric thrill take her. It was what she had wanted, the sudden pulsating thrill of being claimed, of a cock shoving into her desperate, needy pussy at last. And all while she was staring out into the class room, seeing those eyes on her, on the droplets of saliva all over her breasts. On the fact that she was a taking a thick Aerodactyl cock in full, shameless view of them.

More hands slipped under the table now as the sight of Roxanne outright getting fucked was starting to 'convince' the few students who hadn't already been toying with themselves to start. Even as her eyes stared forward, they took a risk in assuming that they wouldn't get caught, that her thoughts would be first and foremost on the task at hand and the pleasure she was feeling. It was a big risk, but one they couldn't resist taking as they marveled at the sight of the gorgeous woman bent over her desk. Fingers sank into slick pussies and grasped rigid cocks as people felt mildly more shame than their teacher about their indulgences.

As her Aerodactyl began to fuck her quick and hard, Roxanne focused on trying to continue the lesson, as ill advised an idea as that may have been. "Now then," she panted. "As you can see, Aerodactyl is a much more active partner than the Pokemon we've studied previously in this course." Her breath was quick and her voice kept stopping and shuddering, twisting around delighted noises as she felt the cock hammering into her greedy twat. She was determined to see this through to the end of the lesson even as she fought down the moans that struggled to slip out of her throat. "There is no official correlation in size of a Pokemon or their genitals and the likelihood they will assert themselves as human partners, and it can vary even by members of the species, but Aerodactyl are definitely a species among rock types who are likely to take charge."

She had learned that through fucking many of them.

Roxanne's fingers gripped the desk, knuckles bone white as she held on tightly, the steady back and forth use of her body leaving her bubbling up with a continued, aggressive need. She wasn't going to get any better about this, of that she was absolutely certain. Her libido didn't come down when it flared up, only got hotter, an she was going to have to fight against it to keep her lesson going, even as Aerodactyl's thick cock slammed deep into her. The harsh thrusts were even making noise, getting loud and echoing through the room, through the frustrated noises of hushed breaths amid students fighting even harder than she was to keep their pleasure quiet.

"It is theorized that the nature of Aerodactyl as an endangered species revived from fossil has something to do with their sexual ferocity, an innate desire to breed and repopulate their dwindling numbers that--ah, it feels so fucking good!" She threw her head back, slamming her fist down onto the desk, frustrated and drifting away from her point and from everything sensible about what she was trying to say. Her lesson was being derailed by her own hungers, and as she looked back out into the crowd of her class, she could feel the lust and the desire practically throbbing off of the other students, all of them unable to keep their eyes off of her as she indulged in her frantic need to get fucked.

Shakily, she continued. "Repopulate their dwindling numbers and restore their species. Naturally, they can't do that with humans, but the impossibility of Pokemon breeding humans does not change their sexual habits and their proclivities. Others say that they are just more--ah! Deeper, boy!" She winced, shuddering and losing herself to the pleasure more and more. The struggle to hold on only grew worse with each thrust. "Just more dominant, likely due to their ferocious strength and the need to show their status. But the--fuck!"

In full view of her class, Roxanne lost control. She had tried to hold it back, she really had. But she couldn't any longer. The lesson had so much more to go and so many things to say, but she couldn't keep it together, ending up crying out in delight as she threw her head back, slamming her first repeatedly onto the desk. Her pussy clenched down around Aerodactyl's cock, spasming greedily around it and trying to milk it of its load as she bucked and twisted excitedly. It felt so good, so searingly delightful and pure. The perfect swell of sensation burning through her all at once, the orgasmic delight capped off with a harsh roar from the Pokemon slamming into her and blowing his load, leaving her so gone that she wasn't even noticing the sounds and expressions of students finding their own climaxes to the sight of her enraptured. She was too gone and focused on what she felt to realize what was happening around her anymore.

Coming down slow from her high, Roxanne shuddered, biting her lip as she resisted the urge to slump right down onto the desk. "Nngh. L-let's uh... Let's call this a day early. Class dismissed." The lesson had gone off the rails, and she lay there shuddering, feeling all that warm cum inside of her. She had faltered in keeping herself steady, in trying to remain focused on the lesson and on teaching them what they needed to know. But once the last of the students filed out and the door was shut behind her, Roxanne stopped worrying about her failures, and started to rock back and forth on her Aerodactyl's cock. "But not you," she told the Pokemon still buried inside of her. "You have an exam right now."
