The Lesson

Button Mash groaned to himself. What would normally be a typical Thursday night, packed with gaming, eating junk food, and staying up late, had turned into study time. Due to his lazy teenage lifestyle, he never attended to his studies, and now his grades were suffering. His mother decided that the best course of action was to have a weekly tutor come over and help him get his grades up. This meant no video games, no late nights, and worst of all, no junk food.

He was sat at the dining room table, a notepad, a textbook, a calculator, a fresh ink pot, a large jug of water and a small plate of fruit and vegetables placed atop it. Everything he needed to...study. Button was slumped over the table, half awake, half asleep. His mother was out, and while he had considered just sleeping his way through the day, his mother was not a force to be reckoned with.

As he lay his head on the table in a half-dazed state, he could hear the clock on the wall tick away. He didn’t have the energy to lift his head up to read the clock, nor to lift his black hoodie from his head. He was wearing his typical black hoodie, as well as a grey t-shirt underneath, some blue denim jeans, and a pair of trainers. Rather normal attire for a young 18-year-old colt, especially ones that loved to play video games as much as Button. He let a groan of boredom, waiting for his tutor to arrive. He literally wanted to do anything else but study.

The doorbell rang, breaking Button out of his trance-like state. He shot up in his chair, as the sound of the doorbell reverberated throughout the house. Groggily, he stood up and made his way over to the front door in a daze, barely unable to comprehend what was happening until he opened to door. “Hey there, you must be my tuuuuuu…” Button Mash started and didn’t finish, as he was perfectly eye level with an enormous pair of breasts. Button had seen plenty of huge tits; when he wasn’t being an epic gamer, he was jerking his joystick to some of the fattest jugs in Equestria. The Royal Sisters, Celestia and Luna, were among the biggest in the land, with their gargantuan mammaries like pairs of juicy beanbags that hung fat and juicy all the way down to the floor. This, however, was the fattest pair of tits he had seen in person. They were easily bigger than watermelons, perhaps even yoga balls!

He tilted his head upwards, to see the stupendous jugs connect to Twilight Sparkle, Princess of Equestria and Element of Magic. She was standing right there, at his door, dressed in way too small clothing. Her bountiful breasts were clothed in a tight, white button-up shirt, which seemed to be straining at the buttons. She was wearing a black pencil skirt, which didn’t do much to cover her wicked hips; he could see her panties peeping underneath. Finally, she wore a purple blazer, black heels, and glasses. She certainly looked like a tutor, save for the huge boobs begging to be freed.

“Your tuuutor? Hi there! Button, am I right?" Twilight giggled out, seemingly oblivious as to why Button had lost his train of thought. He regained his composure, which wasn’t easy, as his eyes fought to not stare at her huge juicy boobs.

“Y-yeah! That’s right! Please, come on in!” Button said as he let Twilight in through the front door. He led her into the dining room, with his notebook, textbook, and pencil ready to go. “Please, make yourself at home...Ms. Sparkle.” Button said. It felt so...weird...to have a princess in his own home. Twilight sat herself down at the chair opposite to his, using her magic to apparate a notebook out of thin air.

“Oh please, Button. There’s no need for the ‘Ms Twilight.’ I’m not that much older than you, young man! Call me Twilight, please.” Button gave a fast nod and sat down, barely able to stop thinking about Twilights huge boobs. The mere thought of them was driving him crazy! How the hell was his mom able to get Twilight Sparkle as a tutor? Why was she dressed so...skimpily? “So, Button, I hear you’re having trouble with mathematics. What areas specifically? Algebra? Loooong division?” Twilight inquired, as she magicked up a quill, ready to start teaching this young colt.

“Umm...all of the above. I haven’t exactly been...paying attention.” Button admitted, the blush on his face growing redder as he nervously scratched the back of his head. He never paid attention in class whatsoever. He was a Twilight, however, had is full attention. Nothing against his math teacher, she just didn’t have a huge pair of boobs to keep him watching.

“That’s okay! We can start at the beginning if you want!” Twilight said as she reached her hand over the table to try to grab the textbook. Why she didn’t use her magic to simple levitate towards her was weird, but it meant Button got an eyeful of Twilights enormous cleavage. He couldn’t hide the fact that he was staring directly at her tits, which causing his cock to harden in his pants. He bit his lip, hoping Twilight hadn’t noticed his staring and erection.

Twilight, however, still couldn’t reach the book, so she bent over further, causing her shirt to strain even more, as the pressure reached its limit. Suddenly, one of the buttons on white button-up shirt to pop off with a loud zip, flying past Buttons head, hitting the wall opposite to Twilight. Her cleavage was now even more exposed, more of that juicy purple boobflesh on display. Strangely, Twilight didn’t seem to notice the button bursting boob bonanza, and grabbed the textbook she had been trying to reach.

Button couldn’t believe his eyes. Twilight’s huge boobs had popped off a shirt button, leaving him with a wonderful view of her huge but constricted titties. How come she didn’t notice it? The sound of the button popping off was certainly loud enough to catch him off-guard, but even if she didn’t hear that, she must’ve felt it. What was happening?

“Why don’t we start with some algebra? It’s not as hard as most people make it out to be.” Twilight assured as she flipped through the pages to find some math problems they could study. Button snapped out of his boob dazed state, remembering what he was there for. He needed to study, no matter how huge Twi’s boobs are.
“Yeah, sure. That’d be good. I know a little bit about algebra and stuff, but I’m not sure about the super hard stuff.” Button admitted, as he grabbed his own quill, and opened his notebook, ready to write down whatever he needed to.

“Okay! Let’s start simple then. ‘x + 4 = 9’ What is x?” Twilight said. Button wrote down the problem and tapped his head, trying to use his brain.

“Um...okay...so...9 minus 4...5? It’s 5, right?” Button asked.

“You’re right! Well done!” Twilight said, giving him a warm smile, which made Button feel content and warm inside. Sure, it wasn’t exactly the hardest problem in the universe, but receiving praise was always nice. It was why Button still played Cooking Mamare. “Alright, let’s try this one. ‘x + 9 = 18 - 2x’ What is x?”

Button jotted down that problem next, biting the end of his quill nervously. This one certainly seemed much harder. “Umm...add the 9...wait, no...I don’t get it…” Button admitted, blushing sheepishly.

“It’s okay! I suppose I did throw you in at the deep end!” Twilight chuckled, causing her bouncy boobs to jiggle. “Still, that’s what I’m here for! How about trying to balance both of the sides?” Twilight suggested, before catching the eye of the plate of fruit and veggies. “Oooh, carrots!” Twilight exclaimed, leaning over yet again to help herself as she eyed up a particularly juicy carrot.

Just as before, as soon as she bent over and put that pressure on her shirt, another button was sent flying, shooting off with a loud zip, causing even more of her enormous boobs to spill out of her tight white shirt. Again, she didn’t seem to notice as she got hold of a carrot, before sitting back down and helping herself. “Mmm, your mother certainly has good taste in carrots!” Twilight joked, nomming away at the vegetable.

Button was in a state of awe, his jaw slack and open, as he gazed at Twilights bountiful bouncy bosom. How could she possibly not notice her massive titties were spilling out of her shirt. Was there something going on? Or was he going crazy? He shook his head, trying to stop thinking about Twilight and her big fat titties. He had a problem to solve. “Okay...umm...minus the 9 from that...add a 2x...leaves us with 3x = 9….it’s 3. It’s gotta be 3.” Button finished, having scribbled out each process with his quill, leaving a bit of a mess on the page.

“That’s correct! Very nicely done! I’m proud of you already!” Twilight beamed, causing a blush to spread on Buttons cheeks. He was trying his best not to look at her tits, but it was a losing battle. He could see how many buttons she had left holding her shirt together, and it wasn’t many. The last thing he needed right now was to pitch a tent during his first tutor session.

“Alright, now that you’ve gotten that down, let’s see if you can do this one.” Twilight said, smirking as she flipped through the pages of the textbook, trying to find a harder question. Button could see her eyes light up as she found the question she was looking for. “‘2x - 6 x 100^2 = x + 200.85 x 100.’ Think you can solve that? Don’t worry, you’re allowed to use a calculator for this problem!” Twilight chuckled, as she went to write something down in her notebook. She gave a grunt of frustration, as she shook her quill. “My quill’s low on ink. Mind if I top up, Button?” She said, gesturing towards the inkpot on the table. Button gave a nod of approval, before watching her lean over the table once again, causing her shirt to tighten up. He felt a strange sense of dejavu creep upon him.

With a mighty snap, yet another button of Twilights was jettisoned from the shirt, exposing even more juicy titflesh for the young stallion to gaze upon. Upon closer inspection, he realised that almost all the buttons on her shirt holding her cleavage together and keeping her decent had all but snapped off due to straining, save for one. There was only one button holding Twilight’s shirt together. Her boobs were spilling out tremendously, the shirt was only covering her juicy nipples, although he could still see the edge of them. With her quill all inked up, she sat back down, once again oblivious to what had happened, despite the fact there was more boob than there was shirt.

Button grunted, realising that he was fully hard, his stiff cock bulging and throbbing against the fabric. If Twilight was still bending forward, she would be able to see his dick trying to tear through his pants. He closed his eyes, as he tried to figure out the problem. “2x - 6 x 100^2 = x + 200.85 x 100...multiply the numbers...2x - 60000 = x + 20085...add the numbers...take away the…” Button froze, as he realised what the answer to the question was.

“Hm? What’s the answer, Button?” Twilight inquired, innocently.

“It’s 80085.” Button said, his voice shaking, his cock throbbing harder than ever.

“Something the matter, Button?” Twilight asked, her voice sincere. Button didn’t dare open his eyes, fearing he would be drawn in by the power of her tits. He inhaled, trying to build up some courage before he spoke.

“Umm...Twilight….your boobs have busted through your shirt.” Button pointed out, still not daring to open his eyes, partly out of fear of staring at her huge tits, but he didn’t want to see what happened when he pointed it out. Twilight simply just stared down at her bust, and then back at Button.

“Is that a problem?” Twilight responded casually, a smirk spreading across her face.

Whatever response Button was expecting, it certainly wasn’t that.

“W-what?” He stuttered out.

Twilight adjusted her glasses, maintaining her smirk as she looked him dead in the eyes.
"There's no need to play innocent, Button. I know what you like. I saw how much you...appreciated the princesses’ curves. Look at you, answering questions you were struggling with before, and all you needed was some large titties to stare at. Unless, of course, you have a problem with that?"

If Buttons jaw could drop any further, it would’ve gone through the floor, and into the ground. He wasn’t exactly sure how to respond to that. All it did was make his dick super hard. The bulge in his pants had a large stain on it from all the pre-cum spurting out. Before he had time to fully process the implications of what was said, Twilight had walked around the table, and she was standing before him, licking her lips as she eyed up his monstrous erection.

“You poor thing, having to conceal yourself around such a busty mare~” She teased, as she placed her hand on his bulge, feeling it throb through the fabric. Button moaned softly, as Twilight’s touch made him even harder. “Let me see that monster~” She breathed, as her hand made its way to his zipper.

She had barely even pulled it down before his gargantuan bare cock burst through, almost cockslapping Twiligh in the face. She yelped in surprise. She had expected him to be big, but not this big. “Oh my...how did you hide this from me for so long~?” Twilight chuckled, as she apperated a tape measure from out of nowhere to measure his length. Using her magic, the tape measure extended from his base, all the way from his tip. “33 inches...sweet Celestia…” Twilight moaned, while the tape measure wrapped around his dick. “12 inches around~” She drooled, as the appareated the tape measure away. She could barely wrap her hands around his cock, it’s size too monstrous for her to properly grasp it. Nevertheless, she could feel him throb and shiver in pleasure.

Button had jerked off many times in his life, but it felt so… different to have a girl touch his dick. Twilight got onto her knees, increasing her jacking speed, giving his tip an experiment lick. Button bucked his hips, letting out a loud moan, which made Twilight grin as she began to suck his cock.“Holy f-fuck…” Button groaned, watching Twilight bob her head up and down the tip of his cock, as her hands worked the rest of his shaft. He was continuously pumping hot and tasty pre-cum into her mouth, which she swallowed eagerly, gulping it down with no problem.

With every bob of her head, she was forcing herself deeper and further down onto his cock, trying to force more of it down her tight throat. It was a quite a challenge given Buttons humongous cock, but Twilight was making progress. Before long, she was deepthroating a large portion of his shaft, gargling around his cock, drooling out of her mouth, as Button started bucking into her mouth.

“Fuh-fuck! Gonna c-cum!” Button grunted, as he felt his balls tighten. At hearing that, Twilight popped his cock out of her mouth, and started to jerk him off, aiming at her tits.

“Do it, Button. Cum all over my fat fucking titties. Coat them with your jizz!” Twilight teased, jerking off his cock at lightning fast speed, opening her mouth, ready for a full on facial. Whatever she was expecting, she wasn’t prepared for what Button had to offer. A huge blast of cum erupted from his cock like a firehose, drenching Twilight and her breasts in his thick hot spunk. It was quickly followed by second blast of cum, coating the already cum coated Twilight with more cum. His load lessened with each cumshot, until finally all that was left were a few little drips of seed on the end of his cock. Twilight was coated from head to toe in Button’s jizz, almost as white as Celestia herself.

“Sweet Celestia...Twilight...I’m so sorry…” Button apologised for his mega cum blast. Never when he masturbated had he been able to pull off a cumshot of such magnitude. Much to his surprise, Twilight let out a giggle, as she licked her fingers clean of cum, her horn lighting up.

“Button, there’s no need to apologise. That was amazing.” Twilight smirked as she used her magic to clean herself, levitating Buttons cum above herself. She opened her mouth, and the magical floating cum ball made it’s way to her, letting her slurp up the rest of his yummy cum, while keeping herself relatively clean. Button could only sit and watch in amazement, as his once erect monster cock was now soft. Twilight devoured the rest of his cum, licking her lips clean, getting back on her feet.

“That was a lot of fun, wasn’t it~?” Twilight inquired, while Buttons eyes fell on her breasts again. Despite everything that had happened, her massive tits were still being contained by her shirt with one button left. “You love huge tits, right~? They’re all yours~” Twilight cooed, stepping closer to him, forcing his face in between her massive melons.

“Y-you mean it?” Button said, his eyes lighting up. The thought of playing with Twilight’s mega boobs was exciting the young stallion, so much so that his cock was starting to harden again. Twilight chuckled at the colt’s enthusiasm. Twilight simply grabbed his wrists, and planted his hands on her boobs, sinking them into the immense titflesh.

“I mean it. Do whatever you want to them~”Twilight cooed, raising her arms, allowing Button full access to her enormous chest. He wasted no time and began squeezing her massive tits with hands, causing her to let out a giggled moan. He jiggled them in his hands, watching them wobble like jelly. It was almost hypnotising.

“Damn Twi...your tits are awesome…” Button said, a goofy grin on his face, which made Twilight giggle. He hefted her breast up, until his face was directly in front of one of her juicy nipples. He opened his mouth, starting to suck and lick at them, as if he was trying to milk her tits. With one hand holding her boobs up to his mouth, the other hand landed on her nipple, twisting and tweaking it, pleasuring Twilights boobs.

“Mmm, that’s it, Button, suck my big fat titties~” Twilight groaned, stroking his hair as he sucked on her juicy nipples, before softly biting them, making her squeal in delight. He simply couldn’t get over how enormous her breasts were. They felt so heavy, and every slight move mad them jiggle like jelly. He just wanted to play with them all day. He wanted to fuck them and cum all over her enormous fuckpillows. The thought of drenching them in his cum yet again made him harder than a rock, as his rod stood up attentive, Twilight stroking the beast in her hand.

“Sweet Celestia...already erect again~” She exclaimed, as if she was amazed at how much stamina this teenage fuckstud had. She simply couldn’t take it anymore. She pulled him away from her huge titties, before turning around and bending over, hiking up her skirt, exposing her gargantuan ass.

“Come on, Button. Wreck me with that fucking bitchbreaker~!” Twilight moaned, swaying her ass to and fro, teasing him with her big fat booty. She had pulled her panties off so he could see her soaking wet pussy and juicy asshole. He approached her, letting his hands sink into her ass, resting his cock between her buttcheeks, grinding against them. They were soft and jiggly, like her breasts. And just like her breasts, her ass was simply enormous. He directed his cock towards her glistening pussy, his tip teasing the entrance of her cunt. He pulled back, ready to slam into Twilights hungry pussy, however he had miscalculated the position

“Aaaaieeee!” Twilight screamed as Button’s enormous monster cock slammed into her tight, unprepared asshole. He didn’t go in completely dry, but she still wasn’t expecting it. When Button realised this, he tried to pulled out while apologising profusely.

“Oh Celestia….I’m so sorry Twilight!” He exclaimed, a strong blush of embarrassment flooding his face. However, Twilight stopped him from pulling out, thrusting herself back down onto his massive dick.

“It’s alright, Button! Could’ve used a bit of warning, but I’m not about to complain about assfucking~” She teased, gently bouncing up and down, sending waves of pleasure down both of their spines. Twilight's ass bouncing up and down his cock was a dream come true, and he certainly didn’t want this dream to end. Wasting no time, Button grabbed hold off Twilights waist, pumping his hips like a piston, thrusting in and out of her slutty asshole.

Twilight could feel her eyes roll to the back of her head. Despite her days as a buttslut, Buttons huge beast of a cock was really stretching out her asshole. For most mares, it would be too much. But for Twilight, it was a challenge. She needed that cock to destroy her fat mare ass.

“Mm...fucking take it...slutty pony whore…” Button grunted. He was really getting into it now, enough to start dirty talking an Equestrian Princess. His thrusting speed was slowly increasing, the power behind each slam growing as time went on. The only thing he needed now was to destroy Twilights eager and hungry asshole.

“Fuuuuuuck...gonna cum, Twi…” Button moaned, as his hips moved like a blur, using Twilight like the cocksleeve she was. Her asshole was truly being stretched to its limits, and she was loving every second of it.

“Mmm, fuck! Fill me with your cum! Dump your load in my ass!” Twilight screamed as Button hit his climax, his balls tightening up. With one last powerful thrust and loud grunt, he rammed himself as deep into Twilights ass as he could, pumping her full of his potent cum. Her stomach began to swell up instantly from the pure volume of his jizz, making her look 9 months pregnant in no time. Twilight was in pure ecstasy, her pussy spraying her juices out like a sprinkler. She was rubbing her clit furiously, cumming just as hard as Button. Before long, Twilights stomach was touching the floor, easily the size of a large yoga ball, and Button was still pumping her full of cum.

After what felt like a couple of minutes of cumming and seeing Twilight bloated out like a balloon the size of a giant beach ball, Buttons ballsack started to ease up, the frequency and amount of his loads gradually slowing down. Once he had stopped cumming completely, he pulled out of Twilights asshole, collapsing on the floor in exhaustion. Her asshole practically exploded with cum, pouring out onto the floor, as she laid on her enormously bloated stomach.

“Mmm...Button...that was wonderful!” Twilight moaned out, still recovering from multiple earth-shattering orgasms. “You got every question right, with a little motivation, of course~” She teased, using her magic to turn herself around to face him. He was still a little dazed, but he was smiling back up at his titillating tutor.

“Heh...thanks...helps that my tutor is a princess...and a slut~” He grinned, as he lay on his back, feeling all the blood rush from his cock back to his head. Twilight was using her magic to reconstruct her outfit, replacing all of the broken buttons on her shirt. With a flash of her horn, she had her diary in one hand, and a quill in another.

“So, what’s your schedule looking, Button? Can you do the same time next week?” Twilight inquired, looking down on the dazed stud, who couldn’t believe his ears.

“Oh,next week?” He said, getting himself up off the floor, and putting his pants back on.

“Of course! I’ll have to revise with you until the end of term, so I can ensure you still know it all. Of course, you’ll need to study up over the summer, and when you get back to school. That is, unless, you’d prefer your mother to hook you up with a different tutor.” Twilight explained, walking back on over to the table, packing up her things. For Button, the choice was obvious.

“Fuck no! You’re awesome, Twilight. I don’t wanna study with any other pony.” He smirked, joining Twilight at the table.

“Aw, glad you think so, Button. Anywho, your mother will be back in about 10 minutes, that gives us enough time to go over everything we’ve learned today...or you could fuck my face again~” Twilight said, eyeing the clock on the wall, and then Buttons crotch, which was starting to get hard again.

“Oh fuck yes.” Button uttered. Maybe math wasn’t so bad after all.
