"Alright, class, this concludes today's sex-ed lesson," Linda announced, clapping her paws in the same moment the recess bell rang. "I wish you kids all a lovely day, and if any of you has any further questions, don't hesitate to come to me after any class and ask them. I know that this is a sensitive subject, so I won't tell anyone if you don't want me to."

The vixen waved at her young subjects as they began to pack their things, stuffing pencil cases and notebooks into their bags in the messiest and noisiest way possible. However, not a moment later the bustle paused as one of them blurted out "penis" and half of the class burst into giggles and laughter. Linda sighed and shook her head, "Jake, please keep your oh-so-funny commentary for yourself, will you? This is a serious matter."

"Yes, Ms. Pixie," the little rodent responded, feigning remorse with a barely contained grin. His eyes met with his seatmate's, the grin widening for yet another quip, but the teacher's icy glare shut him up in time.

As the students left her classroom one by one, chatting and giggling about the naughty contents of their first lesson of sex-ed, Linda removed the anatomical diagrams from the blackboard and stowed them under her desk. Every year, she was amazed at how much laughter the simple cross section of a guy's and a gal's reproductive system could cause, but then again, they were all just kids.

"Ummm, Ms. Pixie?" A soft voice suddenly addressed her and the vixen jerked up, almost bumping her head against the desk. One of her students had stayed, and of all people, the one she least expected. Trevor was a shy little bunny with white and brown mottled fur who sat in the second row, and he rarely stood out in any way, positive nor negative, so him approaching her with a question was a surprise.

"Oh, Trevor! How can I help you, my dear?" she asked, taking a seat and cocking her head.

The bunny blushed and averted his gaze, nervously tapping his large foot on the ground and fumbling with the laces of his forest green hoodie. "W-well, i-it's... I was... w-wondering..."

A big smile popped onto Linda's muzzle when she saw him struggling to ask his question, but she didn't interrupt him yet and just encouraged him with a nod. She wanted him to get to the point all by himself, and besides, this was simply too adorable, the timid innocence melting her heart.

"The d-diagrams... it doesn't look anything like m-mine," he confessed.

The vixen bit her tongue to stifle a laugh as she realized his dilemma. She had mentioned the answer to his question several times in class, but somehow, he had still found a way not to listen to any of it. Curbing her amusement, she cooed softly, "As I said before, don't worry about it. Penises come in all shapes and forms, and they are all perfectly fine and valid."

"No, no, it's not about the shape," Trevor objected hastily. "It's just... mine is much bigger and I'm... w-worried that something is wrong with it. M-maybe I'm sick?"

"Bigger?" Linda whispered with a raised brow.

"Yes, look!" Before the vixen could stop the bunny, he had already grabbed his waistband and dropped his gray sweatpants to the ground, revealing a fat rosy cock that was big enough to reach to his knees and a pair of massively oversized balls. His tight white briefs failed to conceal any of his endowment, and judging by the floppiness of his dick, he wasn't even hard yet. "It b-barely even fits in my pants. T-this can't be normal, right?"

"Holy shit!" Linda yipped, instantly pressing a paw onto her muzzle, but it was too late already.

Obviously, teachers were instructed not to use swear words, and in this particular instance, their effect was even more drastic. She could watch the rabbit's confidence crumbling in real time, his ears flopping down and his eyes filling with tears. His chest jumped with a sob and he whimpered, "I-It's that b-bad, isn't it?"

"Oh no, it's not bad! Not at all! No, it looks beautiful!" Linda hastily reassured him, and she wasn't even lying. A radiant blush glowed on her cheeks as she stared at his swaying schlong, and even though she knew that she should avert her eyes, she just couldn't do it. The sight was too tantalizing and too unexpected, and as she lost herself in the view, her mind started diving into ever hornier fantasies. If he was soft right now, what would it look like if he was hard? What would that throbbing monstrosity feel like? What would the dewy-eyed bunny sound like when he shoved it inside her? And was he still shooting blanks or were those fat nuts already full with warm, thick cum?

Finally, Linda realized that she had to stop staring at her student's dick. What was she thinking? Only because he was unusually hung for his age? She forced herself to look up at his face and crossed her legs, but the damage was done. Her panties were soaked, her pussy squelched with every movement, and she was huffing with arousal.

Fortunately, the meaning of her wanton stare was completely lost on Trevor, and he looked at her with big, puzzled eyes. His whiskers twitched nervously as he asked her, "Beautiful? Are you sure? It's not too big? I mean, it gets even bigger sometimes, really hard and throbby."

"Bigger...?" Linda gasped under her breath. The bunny's words instantly rekindled her horny imagination and her eyes slipped back to his huge dong. She rubbed her forehead and smacked her lips, collecting herself to sound as calm and professional as she could, telling him to stow that delicious monstrosity in his sweatpants. Unfortunately, her arousal got the better of her and as she spoke, her voice vibrated with lust. Not that Trevor would notice, she hoped. "Don't worry, dear. It's absolutely perfect as is, and it's completely normal that it grows bigger now and then. Now, if you..."

"But how does my pee-pee even fit inside a girl?"

Frankly, the vixen wondered the same, mentally comparing the size of his cock with her toys. Obviously, her horny mind wouldn't stop there, and her thoughts quickly spiraled out of control. Before she knew it, she was full-on fantasizing about how he grabbed her hips with his soft paws and shoved his massive meat inside her, pounded her right here on her desk and made her howl with bliss, and when her gaze wandered back up to Trevor's adorable face, she licked her lips and made bedroom eyes at the confused boy.

"Ms. Pixie, are you okay? You look... weird."

"Oh, don't worry about me, dear. I'm fine," Linda purred and leaned closer to the bunny. "Also, I'm very proud of you for coming to me and asking me your important question. I'm pleasantly surprised by your initiative, and I think you deserve a little reward for it, Trevor." Wait, what was she saying there?

"A-a reward? What do you mean?"

"Since you're so worried about your size, how about I anticipate the contents of the coming lessons and show you that you have nothing to worry about?" It surprised the vixen how easy this was, the words flowing over her lips as if they had already been waiting their turn. And yet, the same words made her heart hammer in her chest and create a lump in her throat.

Trevor's fluffy jaw dropped and he stared at her with plate-like eyes as his preteen brain tried to process her offer. "So it's an extra lesson? Right now? What are you going to show me? More diagrams?" he wondered out loud, slightly concerned at the prospect of having another lesson after the school day was already over.

Linda chuckled at her student's response and gently shook her head. She knew that she could still find an excuse and end it right here and now. But while part of her mind kept urging her to stop, instilling doubts and worries, one glance at the bunny's fat dick overturned it all. So she rose from her seat, walked around her desk with a swaying tail, and stopped right next to the bunny. Wordlessly, she lifted her pleated black skirt and revealed her soaked white panties. Although Trevor was blushing up a storm and trying his best not to look, his eyes inevitably landed on her crotch, and once she was sure of his attention, she peeled the last piece of fabric off her crotch and revealed her plump, dripping pussy to the stunned gasp of the boy.

"I've promised you a reward, silly, not an extra lesson," the vixen cooed and sat onto her desk, leaning back and spreading her legs apart to grant him an even better view of her cunt. The thrill racing up and down her spine was becoming nearly unbearable as she exposed herself to his innocent eyes. "Unless you want it to be one~ Now, tell you what, Trevor: If you promise to keep this all to yourself, I'll let you put it in, okay?"

"Okay! But you promise not to tell anyone either, yes, Ms. Pixie?" the bunny boy responded, excitedly sidling from one foot to the other. His eyes were still glued to her pussy, and while his young mind barely comprehended his own excitement, his body knew exactly what was going on. His bouncing, jiggling penis was already a sight to behold, and now it was also starting to get hard. His swelling cock meat throbbed and pulsed vigorously and rapidly grew to even more ridiculous proportions.

"Yes, nobody but us will know about this. Trust me," the vixen moaned.

Trevor nodded and finally approached Linda with small, hesitant steps until less than a foot separated his lips and her folds. However, now he st stood there, bent over in awkward silence and irresolutely staring at her cunt. She could tell that he had questions, lots of questions, but was too shy to ask any of them.

"What are you thinking about, dear?"

"I-It looks so big and red and swollen! Does it hurt? Also, why is it so wet? Did you pee yourself?"

The bunny's questions were more than justified coming from a preteen, but they still cracked the vixen up. She could barely hold back her laughter, and she bit her tongue hard enough to wince in pain. Fortunately, he was too enthralled by her pussy to notice. "No, I didn't wet myself, and I'm also not hurt. That's completely normal for girls. At least, when we're aroused."

"So you're aroused right now? Why?"

"I'm aroused because of you, dear. Because I like how you look and I like seeing your gorgeous penis."

"Because of me? Really?" Trevor squeaked, blushing furiously at the compliment.

"Yes, and look at your dick. It's getting hard again, isn't it? That means you're getting aroused as well, and it's much the same with me. Only that I don't get hard, but puffy, red, and wet instead."

"I'm aroused?" Finally, the young bunny wrenched his eyes away from his teacher's pussy to stare at his own giant erection in awe. "Wow, it's even bigger than normally." It was now almost as long as his own arm, and the sight of the colossal schlong on the cute, little cub pushed Linda's lust into overdrive. Her body was burning with arousal, so much so that she was gasping for breath and sweating under her dress suit. Since they were all on their own anyway, she decided to get rid of that stuffy, restrictive outfit. She hurriedly stripped her vest and unbuttoned her blouse, liberating her large bust from its confines.

After Trevor was done ogling his dick, he looked back up and gasped in surprise as he laid eyes on his teacher's barely concealed boobs, a visible shiver of arousal sweeping through his slender body. Something unfamiliar spread through him and his gaze began to switch back and forth between Linda's face, her tits, her pussy, and his own cock, his eyes flicking faster and faster and his penis throbbing harder and harder before he suddenly froze. The confusion faded and a triumphant smile beamed on his lips as he finally connected the dots. "That's how arousal works? I look at a pretty girl, feel all tingly, and get hard?"

"Exactly," Linda cheered, a little more enthusiastically than planned. "So you like what you see?"

"Yes, you are really pretty! It gets extra special tingly when I look at you, Ms. Pixie," Trevor said. "And it feels so good, too."

"Shall I tell you what feels even better than looking?"

"Yes?"

"If you stick it inside me."

"Yes!" The cub's eyes sparkled at the prospect, and he nodded eagerly, waddling toward his teacher only to realize with a whimper that she was too high up on the desk. While his cock was bigger than that of most adults, he was still a small boy, and he wouldn't have been able to reach Linda even if he stood on his tiptoes.

The vixen came to the same conclusion and she unceremoniously jumped off the edge of her desk. But before she bent down to him, she took care of the rest of her clothing first. After all, the bunny seemed to like her tits, so why not grant him an even better look? Licking her lips, she stripped her blouse, dropping it next to her skirt, and reached behind her back, fumbling around with the clasp of her bra. It snapped open with a sharp click and released her luscious breasts with plenty of force, letting them dance and dangle much to her student's delight. His cock was harder than ever, throbbing and overflowing with pre, while he beamed at her with hungry eyes.

With the last piece of attire gone, Linda dropped onto her knees before the bunny cub and showed off her naked body, swaying her chest from side to side to tease him with her heavy tits. She knew that this would have serious consequences on his future tastes and kinks, likely getting him into mature girls and maybe even milfs. However, she hardly thought about it because there were more urgent matters at paw. The vixen winked at her young admirer and finally moved onto all fours, wagging her round butt at him and presenting her plump, dripping pussy to her student as if she was a bitch in heat. "It's all yours~"

Despite her encouragement, it took the preteen another moment to process the sight and snap out of his horny daze. Nothing like this had ever happened to him, and of all the people, it was his own teacher who got down and prostrated before him, surrendering all her authority and decency for a fuck. 

Finally, his arousal grew powerful enough to draw him to Linda's luscious bottom like a moth to the flame and he dropped onto his knees behind her.

A mighty shiver raced through Linda as the bunny touched her right butt cheek, but not for long. A split second later, he already pulled his fingers back with a nervous gasp. His coyness and inexperience were still holding him back, and at this rate, she would never get his dick inside her. "Trevor, shall I help you?"

The bunny nodded abashedly and pulled his big ears over his muzzle to hide his blush.

His reaction conjured an even bigger grin on the vixen's muzzle, and she reached behind her, wrapping her paw around his dick and squeezing it firmly enough to make the cub moan. It was just as girthy and warm as she had hoped, already soaked in a sticky lay of pre so it would slide right in, and she only had to pull him closer. In fact, she went beyond that, going so far as to align his tip with her puffy entrance and press them together with a lewd, wet kiss. "Here you go. And now, push!"

This time, Linda's desire wasn't wrapped in a honeyed offer but phrased as a clear, concise demand, and it worked immediately. Trevor's ears perked up and he slammed his hips forward without another thought. Unfortunately, her folds were too slippery and he was too big, so he slipped right off, shoving his bloated cock between her thighs instead. She heard a distraught whine and his eyes were getting suspiciously wet. "Ms. Pixie, I-I'm s-s..."

She quickly shook her head and whispered, "Shhh, it's alright, dear. Just let me guide you, and perhaps do it a little more softly next time, okay?"

Trevor sniffled and nodded quickly, allowing his teacher to move his tip back to her pussy and waiting until she gave him the signal. This time, he didn't jerk his hips with as much force, and finally, the vixen's pussy yielded to the push and spread wide open to accommodate the cub's oversized cock. A sensation of fullness overcame her, drawing a blissful moan from her lips, and she instantly lost her hold on the bunny's penis, but it was far enough inside to stick on its own. So when she repeated her command "Deeper! Push!" he did just that.

A tiny paw grabbed Linda's ample butt and another the base of her tail as the bunny's little fingers clutching her fur, desperate for more leverage to comply and shove his cock deeper inside her. The vixen groaned and dug her claws into the classroom floor as her fluffy student's schlong spread her pussy wide open, inch after inch of fat, throbbing cock meat convincing her that it wasn't just an illusion. However, the stimulation was as twisted as it was glorious, as she wasn't doing it with just some guy, but with one of her young little students in her own classroom, brazenly taking advantage of his innocence and his huge cock. She should've been ashamed, but the only thing ravaging her mind right now was a flaring fire of lust, and the depravity only added to her arousal.

Better yet, Trevor was vocally enjoying the moment as well, moaning and whimpering with confused but genuine pleasure. "Ms. Pixie, you're so warm and soft! My pee-pee tingles so much and so good, I never want it to stop!" he mewled, bending over her and wrapping his fluffy paws around her waist to slam the last inch of his massive cock inside her, showering her with another burst of pleasure. He was now so deep inside her that his dribbling tip nuzzled her cervix and his bloated ball rubbed against her thighs, and when she peeked between her drooping tits, she could clearly see a fat, throbbing bulge on her belly. Even though she had seen his cock, he was exceeding even her naughtiest expectations and she felt fuller than ever before.

Once Trevor bottomed out, he slumped onto his teachers back and wrapped his arms around her, breathing and panting heavily while whispering, "Warm. Tight." Linda chuckled softly and allowed him to relish the sensation, as it was his first time and she wanted him to enjoy it as much as her. However,  for some reason, he still refused to move even after a minute had passed, just letting his pulsing, drooling cock stew inside her pussy while denying her a proper pounding. Finally, lust got the better of her and she urged, "Trevor, dear. You can move now if you want."

"Move? You mean move my pee-pee?"

The vixen giggled as she realized the reason for the hold-up. Of course, she had asked him to stick it in and he had taken it literally, because how was he supposed to know better? They had only just begun the sex-ed course. So she raised her arm and made thrusting movements. "In and out, like this but with your penis. Try it, but slowly."Linda was sure that he would learn quickly once he got to it, hopefully before he blew.

"Ah, okay," the bunny responded with a quick nod, but his face still marked by confusion and innocence as he put her words into action and cautiously pulled his cock out of her.

Much too slowly for Linda's tastes, the tepid tingling of stimulation just enough to fuel her desire but too little to actually satisfy it. She needed more, she needed it now, and so she almost immediately contradicted her own request, "No, faster, Trevor!"

"B-but you..."

"Please, faster, Trevor. Now," the vixen begged, leaning forward in an attempt to assist him.

Once again, the bunny complied and sped up his movement. He still wasn't entirely sure what he was doing when it finally hit him, "Umm, is this b.... uwaaah" A cry of raw pleasure burst from the preteen's muzzle and his timidity took the backseat as he lost control over himself and his instinct took over. Another sqeuaky moan escaped him when he slammed his cock back into the vixen and began to hump her with rapid, shallow thrusts, accelerating rapidly as he lost himself in the mounting spiral of pleasure and stimulation.

"Ms. Pixie, it feels so good! I can't stop," the cub cried out, his words still innocent while his young body succumbed to the primal urge of mating. Every fiber and every muscle in his body acted in union, and he hammered his teacher with all the strength he had to offer, drilling her tight cunt while drowning sensations he had never experienced before.

Linda could do nothing to stop her student from using her as recklessly as a cheap pocket pussy. Her body had completely yielded to his huge cock. Every thrust stirred her tight, sensitive channel, every touch against her cervix kindled a grandiose firework of pleasure, and every slap of his heavy, brimful breeding orbs corroborated her new place as a bitch below him. Her poor mind never stood a chance against the unbridled fervor of a barely pubescent male, and her control over her own thoughts slipped away as they were sucked into the raging storm of lust and pleasure.

Eventually, the vixen was so desperate to be rammed and ruined by her student that she thew all caution and decency out the window and howled, "Yes, don't stop! I love your cock! Fuck me harder, Trevor! Breed me!"

"Yes, Ms. Pixie," the preteen gasped, but instead of going faster, his frenzied thrusts suddenly slowed and faltered. "I-I can't! The tingling! It's too much! It feels like I'm going to explode!"

"That's perfect! Don't worry and just let it happen!"

Trevor nodded with gritted teeth and shoved his cock inside the vixen one more time, going all the way to his balls so she could feel his fat orbs tensing and flexing against her butt as a powerful orgasm took control of his immature brain. His voice flared into a horny howl as he erupted inside her and flooded her pussy with his warm seed, clearly showing that he wasn't shooting blanks anymore. In fact, Linda soon learned that the preteen's giant balls weren't just for show as he just kept throbbing and nutting inside her, his cum sloshing as it filled and bloated her womb.

Finally, the rush of semen drove the teacher over the edge as well and she joined the cub with a desperate moan. "Trevor, so much, so hot! Fuck, I'm cumming!" Her body vibrated with pleasure and she reared up as she came the hardest she had ever come, her climax fueled by the bunny's immense output while she begged for more like a desperate bitch in heat, "Yes, fill me up, Trevor! Get it all inside me!" before her mind lost all cohesion and her speech turned into incomprehensible groans of bliss.

When the vixen's mind-shattering orgasm eventually faded, she was left gasping for breath, with glassy eyes, a swollen, drooping belly, and drenched with sweat. As the fog around her mind cleared, she realized the sheer insanity of what had just happened. She had seduced her preteen student, claimed his first time, and ruined his innocence because he was hung like a stallion and she was too horny for her own good. She had taken him up her cunt, allowed him to fuck her like a cheap toy and pump her full of cum while openly cursing in front of him. This was supposed to be completely wrong. She knew that it was completely wrong... and yet, the sensation of her swollen belly, his throbbing cock, and his soft paws, the sound of his immature, timid voice, the appearance of his slender, fluffy body and his adorable muzzle still turned her on like nothing else. This felt so right. This felt like where she was supposed to be, teaching paws-on sex ed by allowing her student to use her.

In any case, her reward had left Trevor with a rapturous smile on his fluffy, little muzzle. "Whew, you were right! This is really fun!" he raved before collapsing on the vixen.

"I know, right? And would you look at that, your dick fits me absolutely perfectly~" Linda moaned, affectionately rubbing her heavy cum belly as she basked in the afterglow of her orgasm. She had rarely ever felt this full and satisfied, and this had just been the bunny's first time! She couldn't even imagine what he'd be capable of with some more experience under his belt, experience she was very eager to grant him. Perhaps it would even boost his confidence a little and encourage him to be more active during her lessons? In any case, it would be a win-win-situation for everybody involved.

After another minute or so, the bunny started to move again, getting up from her back but not yet pulling out. For some reason, he seemed reluctant. "Ms. Pixie, ummm... do I... can I... may I pull out again?"

"What?" Linda snapped out of her daze and nodded. "Oh, sure! Go ahead, dear."

As soon as she had given him the go ahead, Trevor lost no time ripping his softening cock out of her with a lewd slurp. The excessive force drew another moan from her lips and as she recoiled, her arms gave way and she slumped onto her face.

"Oh no! Are you alright?"

The vixen quickly lifted a paw and chuckled, "Yes, yes, I'm fine. Don't worry. I just need... another moment to recover."

Eventually, Linda's strength returned to her limbs and she got back up on her feet. Not missing a beat, she picked her clothing off her chair and redressed herself, trying her best to conceal her swollen cum belly, but no matter what she tried, Trevor's load defied her attempts and made her look positively pregnant. Luckily, she wasn't in heat at the moment, so she wouldn't actually get pregnant. Although, there was always a chance, and with a load as huge as his, all bets were off.

Once the teacher was back in uniform, she grabbed the bunny's paw, ruffled his hair, and kissed him on the forehead. "Now, there's still a lot more to learn, and if you like you can pay me a visit sometime in the evening for some private lessons. What do you say, Trevor?"

"Oh, yes! Yes, please, Ms. Pixie!" Trevor blurted with a beaming smile and nodded as fast as he could, his long ears flopping and flailing wildly.

"Splendid~ Now, come, dear. I think we've spent more than enough time here in school," Linda reminded him and walked him to the exit. 

The vixen paused the moment she left her classroom, as she thought she heard a rustling. However, when she turned around and inspected the dark room, there was not a single sign of activity. Was she imagining things? She hoped so. She had been foolish to do it here at school, and it was definitely a good idea to shift their next lesson to the secrecy of her home and the softness of her bed. 

"Everything okay, Ms. Pixie?"

"Y-yes, everything okay. Let's get going, alright? Wouldn't want your parents to worry about where you are."

"That's right! I'm already late for lunch! Umm, I think I gotta go then," Trevor gasped, getting jumpy all of a sudden and thumping his feet on the ground. "Can I go now?"

"Oh, sure. Please, don't wait for me. You know the way to the exit yourself, don't you?" Linda chuckled nervously and let go of his paw.

"Yes, I do! Alright! See you tomorrow Ms. Pixie!" Trevor squawked, eagerly waving at his teacher before darting off on his speedy little legs.

"See you tomorrow, Trevor," the vixen replied and waved back at him, but the young bunny was already gone, leaving her alone in the dark corridor with a belly full of cum and a head full of lewd ideas for the lessons to come.
