Dr. Sinclair makes sure that her class knows why condoms won't work for the males of the school

‘Now, Miss Montez. You shouldn’t praise Matt and Adoria for what they have done here, their actions here have put a dent in the lesson plan I had put together. I suppose this means we’ll have to try this again.’ Dr. Sinclair said as she approached Matt and Adoria.

‘For some reason I don’t believe that she’s actually disappointed about how things have turned out…’ Lacey muttered to Roxanne, although she made sure to state it loud enough for the rest of the class to hear.

‘I’ll be glad to assist you with this again, doctor…’ Adoria muttered dreamily, but even though she spoke to Dr. Sinclair she was looking at Matt. Who, in turn, was staring at the Italian slut’s anus as it very rapidly returned to its previously tight state. Apparently Adoria didn’t want his thick load of jizz to escape her anal tunnel.

‘After what you have just pulled, young lady? That wouldn’t be much of a punishment now, would it?’ Dr. Sinclair replied while raising her arched eyebrows. ‘Still, I suppose you can assist me in some other way…’ She mused while tapping her bottom lip.

‘What do you need me to do?’ Adoria asked as she managed to push herself away from the desk she had been bent over, though not without purposely bumping into Matt and trapping his monstrous erection between her ballooning buttocks.

‘I want you to put that tongue of yours to work on my asshole while I slip another condom on that huge, throbbing dick you currently have trapped between your buttcheeks,’ Dr. Sinclair explained. ‘Because I have to admit that I’m curious to see what else you d’Anale women have been taught when it comes to the ass.’ She added with an impish little smirk.

‘I’ll try not to disappoint you.’ Adoria replied with a wicked grin of her own, before reluctantly pulling away from Matt.

Almost as soon as his shaft was freed from the halves of Adoria’s large, soft rear, Dr. Sinclair dropped to her haunches in front of Matt. Yet despite the fact that she had lamented the fact that he and Adoria putting a dent in her lesson plan and that they had to do the presentation again, all the blonde did now was simply stare at the huge cock sticking out of the hole in Matt’s speedos. The obvious lust for monstercock in her eyes as she seemed to scan every last veiny inch turned the young man on so much that a fat bolt of precum blasted from Matt’s cumslt, the **** of it nearly knocked Dr. Sinclair on her ass as the clear goo smacked against her forehead and ended up in her blonde and black tresses.

‘What, one of us doesn’t get to go next? No fair!’ Lola complained, while she continued to furiously finger herself.

‘I’m sorry, Miss Montez. Even though I know all the ladies here would like a turn with Matt here, I simply must continue the lesson,’ Dr. Sinclair replied in the most professional tone of voice she could muster while fresh precum slid down her forehead. ‘Speaking of continuing the lesson, what are you waiting for, Miss d’Anale?’ The blonde asked as she hitched up her criminally short skirt to completely free her firm, tanned buttcheeks.

Adoria glanced at the shapely globes before looking back up at Matt and, while flashing him one last nasty smile, she dropped to her knees behind the taller woman before her face disappeared between her buttocks. When Dr. Sinclair temporarily stopped staring at Matt’s monstercock and instead clenched her eyes shut in pleasure while moaning in pleasure, it became obvious that Adoria knew just how to use her tongue on the blonde doctor’s anus.

‘Oh fuck! I’m definitely going to need something bigger in there now!’ Dr. Sinclair hissed, before tearing open a condom wrapper Matt hadn’t realized she was holding.

But instead of sliding it over Matt’s member, she placed the unrolled condom between her plush lips. Then, with a wink at the cameras that were focusing on her and the monstercock in front of her, she rolled the condom over Matt’s shaft with her mouth. Matt watched in awe how the blonde doctor effortlessly deepthroated the huge pillar of cockmeat that was sticking out from between his legs, while simultaneously rolling a condom over it. When Dr. Sinclair reached the base of his shaft, she winked at him instead of the cameras and pulled her head back.

‘Oh my, you wouldn’t want to make your condom disappear again before we really get started, do you?’ Dr. Sinclair asked when she noticed how the tip of the condom had already been filled with precum.

‘It’s not like I have control over this…’ Matt replied, somewhat embarrassed.

‘Not yet, you mean,’ Dr. Sinclair mused with a naughty smile. ‘Don’t worry, I’m sure you’ll be able to hold yourself back from leaking precum soon enough. If only so you can coat horny little sluts like Adoria here with it whenever you want.’ The blonde said, while pushing her rear back a little further.

‘That definitely sounds like fun,’ Matt admitted with a grin. ‘Anyway, shall we continue the lesson?’

‘I do love an eager student,’ Dr. Sinclair replied with a pleased sigh, before she climbed to her feet and bent over a nearby desk. ‘So, did Adoria do a good job?’ She asked, while grabbing hold of her asscheeks and pulling them apart to reveal her pink, saliva-coated anus.

To answer her question, Matt stepped up behind the blonde and pressed his fat cockhead against her tight backdoor. Dr. Sinclair gasped sharply and Matt felt her juices smacking against his thighs and his beefy balls, still encased in his speedos. After the blonde’s small orgasm had passed, Matt started to push his hips forwards. Dr. Sinclair shrieked in pleasure and showered Matt with more of her girlcum, while the cameras zoomed in on her anus and how it stretched around the girth of Matt’s monstrous shaft.

‘I want you to make me squirt like that, Henry.’ An unfamiliar female voice piped up.

‘Oh, I’m definitely going to try Cassandra.’ Came Henry’s reply, as he brutally worked his hips back and forth.

Like Kaylee and Ruby, Cassandra was one of the girls asked to take care of the boys in class by Dr. Sinclair. Just like them, she was an outrageously slutty young woman with the body of a pornstar and the face of a model. Her hair was black and kept short, it looked almost boyish. Obviously, that was the only thing one could call “boyish” about her. Cassandra’s breasts were about the same size as Ruby, and if she had been wearing a top before she wasn’t any longer. Instead the soft globes were squeezed against the top of her desk, as Henry ruthlessly pounded her ass from behind her. One hand was squeezing one of her jiggling buttocks, while the other was holding the torn remains of her denim short shorts. Now all the schoolgirl was wearing were a pair of blue stripper heels.

Although Matt was curious to see what his other male classmates were up to, feeling the walls of Dr. Sinclair’s anal tunnel hugging his fat shaft reminded him that he had something more important to do. With a grunt, he grabbed Dr. Sinclair’s slender waist and **** his hips forwards. Surprised gasps and disappointed moans came from the class as they witnessed Matt’s monstercock rapidly disappearing into the blonde’s ass on the monitors in front of the classroom. Apparently Matt’s tryst with Adoria had thought him a thing or two about easily fitting something big into something very, very small.

‘Yes!’ Dr. Sinclair howled as her anal tunnel was suddenly very rapidly being filled with a massive, throbbing cock.

‘Oh, the new guy should hurry up. Our first hour of biology is almost over.’ Roxanne stated drily.

‘I don’t think Dr. Sinclair really cares,’ Lacey mused as she looked at the blonde doctor’s sweaty, screaming, happy face. ‘Or maybe she’s lost track of time, it happens to the best of us when we have a monstercock tickling our throat.’

Matt wasn’t exactly keeping track of time himself, all he heard was the blood pumping in his ears and all he saw was Dr. Sinclair bent over that desk. He did become vaguely aware of the fact that he hadn’t felt the blonde’s orgasmic juices smacking against his legs, and he also noticed that his heavy balls, though still in their speedos, were knocking against something. Obviously, he wasn’t about to investigate what it was. If he did, he would find that Adoria had disappeared underneath the desk and was currently frantically drinking down the copious amounts of girlcum that were drooling from Dr. Sinclair’s twitching quim, while Matt’s balls brushed against her chin.

Matt continued to brutally assfuck the blonde for several more minutes, while his classmates watched how he and Adoria turned the previously composed scientist into a screaming, squirting mess. But then, suddenly, Matt stopped. The young man set his jaw and slowly started pulling his hips back, extracting his condom-clad monstercock from Dr. Sinclair’s stretched bowels.

‘Doctor, I’m going to cum.’ Matt stated calmly through clenched teeth.

‘Whu...what?’ Dr. Sinclair muttered, slightly out of breath. ‘Oh yes, of course. Please pay attention, class.’

No one in the classroom had any problem doing that, everyone’s attention was already focused on Matt and Dr. Sinclair anyway. Even Adoria poked her head out from under the desk now that the flow of girlcum escaping from the doctor's twat had lessened somewhat. When Matt’s cockhead finally escaped from the blonde’s ass, the classroom was silent enough to hear an audible *POP!*, and now that she was free to move Dr. Sinclair turned over to lie on her back and look up at Matt. As a result, she flashed her mountainous, tanned boobs at the young man, which had somehow escaped her top because of the way Matt had been shoving her body back and forth. The sight of those huge jugs made it impossible for Matt to hold his orgasm back any longer and with a cry, he came.

The condom rapidly expanded, until it resembled some sort of perverted version of a water balloon. For a moment, it appeared as if the condom was going to be able to hold the vast amounts of spunk Matt’s cock was pumping out. But that moment quickly passed, and a loud tearing sound resounded through the classroom as the condom burst. This was quickly followed by a sharp outcry of joy from Dr. Sinclair, as she was being showered by a deluge of warm, sticky white seed and bits of rubber. To Matt, all of it seemed to be happening in slow motion, while in reality it was over in a few seconds.

‘Now, did that properly show you why condoms won’t work on our male faculty and students?’ Dr. Sinclair asked as she pushed herself away from the desk with some effort. Looking at her now, Matt wasn’t sure where her outfit ended and the cum coating her body began.

‘Yes, Dr. Sinclair.’ The class answered in unison.

‘Good,’ the blonde replied with a proud nod. ‘Now, to make absolutely sure that you girls know how lucky you are I want to spend the second hour of biology showing you just how much spunk the boys here can pump out. So, Lola, Roxanne and Alexia. Would you please grab six buckets for me from the closet in the back of the classroom? And Tom, Henry, Frank, Victor, Hugh and Malcolm? Please line up in front of the class when you’re done with the girls.’

‘Yes, ma’am!’ Lola replied excitedly, as she hopped out of her seat and quickly grabbed two buckets from the closet. Roxanne and Alexia were just as quick to grab two buckets of their own.

‘Dr. Sinclair, what about Matt?’ Lacey asked, noticing that there weren’t enough buckets for every boy in class.

‘I think Matt has deserved a break from assisting me, class,’ Dr. Sinclair mused. ‘Unless, Mister Henderson himself thinks differently?’ She added, while glancing at Matt with an impish glimmer in her eyes.

‘I don’t mind helping out a little more.’ Matt replied, as he joined the other male classmates.

‘That’s the spirit!’ Dr. Sinclair cheered. ‘Lacey, grab another bucket!’
