(Twilight can't stop!)

With one of the flight instructors out for the day in Cloudsdale, many pegasi had been asked to fill in for the replacement. Unfortunately, almost everypony was busy with their errands for that day. It took a bit for word to reach the princesses until Celestia finally sent out a scroll for Twilight to help out. The purple princess tried to reason with her and explain she wouldn't be the best for flying for students. It seemed to be her lucky day that they only needed to brush up on a few history lessons instead.

Reluctantly, Twilight accepted and soon found her way to Cloudsdale while clutching a book close to her chest. She had thought about bringing along her mile long notes but Spike insisted against it. At least she could explain the history of the Wonderbolts and more to a room full of foals! Learning was always such great fun!

As she flew towards the building, she couldn't help but be a little worried. The fact she was going to be teaching made her rather happy, but to a room full of young ponies? Her ears folded back as she took a deep breath and calmed down slightly. Nothing to get worked up over.

Opening the door brought a chorus of cheers and yells as the princess walked inside, smiling to the precious foals. A few of them seemed to take the opportunity to just talk amongst their little classmates without paying much attention. When trying to quiet them down, Twilight did have to resort to knocking on the desk with a hoof.

“Quiet, please. It's time for class. I'll be teaching you about-” Twilight started before giggling sounded out in the back of the room. “Can I please have your attention?”

The small giggles didn't seem to stop and soon she found the source. Rumble, a small colt, had been doodling in his book. Cartoon depictions of random things filled the open pages. Twilight was far less than amused as she magically swiped the book up and held it up for all to see. Maybe he would be embarrassed if she showed the entire class.

“If you don't value your books, surely you already know all there is to learn today?” Twilight said, letting all the foals see the scribbled pages.

Instead of the silence she expected, they all began to laugh and point a hoof at it. Upon turning it around, the princess hardly knew what was so funny until she saw a drawing of herself. She was depicted with overly large wings and a crown in her mouth. The image made the alicorn purse her lips before slamming the book shut and putting it aside.

“Enough,” she said simply and moved over to the blackboard. If she started on the lesson quickly, she could at least divert their little minds.

Taking some chalk, she started out with the beginning of the pegasi history. A quick brush up on it wouldn't hurt before the lessons of the day. She had written a good deal, and rather quickly, along a portion of the board when something small and wet spat her right rump cheek.

The class erupted in laughter as she stood still and tried to assess what just happened. A look back showed a spit ball stuck to her purple rear which she quickly wiped off with a wing. Once she looked to the class, Rumble seemed to struggle in putting the straw away, fumbling with it quickly.

“Rumble,” Twilight said in a low tone. “You don't do that to your teachers. You could severely hurt one of your classmates, or even me!” Seeing he wasn't caring, she decided to take matters in her own hooves, quickly pinning her mane back into a bun via magic.

The class continued their laughing until she strode over and swiped the straw from the colt. The quick action and stern faced seemed to be enough to quiet the class instantly. A quick float of her magic and she put the straw in one of the drawers on the desk. In return, she brought back a quill and some parchment.

“I may be a substitute but I'm still your teacher for the day,” Twilight said, beginning to scribble down on the paper using her magic to move the quill. “I think your teacher would love to hear about how rambunctious you all are when they're away. Especially you, Rumble.”

The colt widened his eyes before he sat up in his seat, his short forelegs reaching up to the parchment. He didn't seem to like the idea of finally being called out on disrupting the class. When he tried flying up to the hovering paper, Twilight pulled him back down with her magic and shook her head.

“Please, don't! I was just playing! I'm sorry,” he apologized, looking worried. Perhaps his teacher was far more strict than Twilight. Maybe this was the one day he thought he could goof off.

“Then what should I tell them? You've practically ruined your book and you've been spitting wads of paper at me. I don't think they would find that very appropriate,” Twilight mentioned, looking down at the colt. The rest of the class watched in silence.

“I'm sorry,” Rumble repeated, looking around and trying to avoid eye contact. “I don't know.. Just don't tell them?”

“I have to tell them something,” Twilight insisted and stopped her writing. Or, did she? She could still give him detention and keep him after class a bit. That might make him wise up. “Would detention be more fitting for you?”

Rumble took a moment to understand the options then quickly nodded.

“Very well then. You're to stay with me after class is over for..an hour,” the princess said, rolling up the parchment in the air before it disappeared. “Understood? No goofing off and certainly no more distractions in class or else your teacher will hear every detail.”

Rumble swallowed in nervousness as he agreed before staying quiet. He seemed to be taking the rest of the class rather seriously, even borrowing a book Twilight lent to him so he didn't have any scribbles obscuring the text. The lesson continued normally for the rest of the class period. Nopony wanted to start up anything with the thread of their teacher hearing about it looming overhead.

The alicorn's lesson kept going until the very last minute when the bell rang. Upon the fillies and colts getting up, Rumble seemed to abide by the rules and stayed seated. The colt was really not wanting to have his troublesome attitude brought up to his teacher in the slightest. At least he was obedient in his fear.

When the last of the students left the room, Twilight closed the door and walked over to the teacher's desk, sitting behind it and pulling up a book to silently read. She could try teaching him more on the lesson but his sudden change in attitude had been enough. Then it was just her and him. Princess and a little colt in a room.

The thought lingered on her mind a bit more as she stared at the pages in her book. The hovering literature lowered enough to let her peek over it at the colt sitting in the back of the room and staring at his desk. Just the two of them. She was basically in control of what to tell him to do. The thought made the mare's hind legs shift as she squirmed in her seat. She shouldn't be letting her mind drift away to such thoughts.

Such ideas weren't really looked highly upon in Equestria. In fact, they would get her sent right to the dungeon if she acted on them. The thought made her frown but then a new one came up. She would only really be sent to the dungeon or worse if she was caught. Nopony had to know, right?

Her hoof moved down and gave a light touch to her folds, already noticing the slight dampness she was giving. He was so young, though. Perfect for teaching more than a history lesson to. There wouldn't be a reason that any other pony should know anyway. She really shouldn't, though.

The alicorn's imagination began to get away from her as she rubbed a bit more to herself behind the desk. It just felt so good to think of such things and touch herself. To have some pleasure as she let her mind dip into the morally wrong. That hoof moved a bit quicker as she propped the book up and let her head rest on the desk.

Scooting back a little, both forelegs joined together between her hinds and rubbed back and forth while she started masturbating in the classroom. The mare let out a soft pant as she hid her face from the colt, unable to control her wings rising in the sensation. It just felt too good to try and ease some tension after all the adventuring and more. She couldn't recall the last time she did such a thing lately.

It wasn't until she heard some shuffling that she sat up, blushing fiercely and covering her lap. Rumble had merely scooted his seat back in boredom. Twilight sighed a bit of relief before her eyes focused on his hind legs hanging off the chair. Between them nestled a pair of little balls, almost begging for her touch.

The silence was deafening before she made a bold choice and magically locked the door to the room.

The click of the lock had Rumble perk up and look around, wondering what happened. Twilight grinned and hid back behind her book, rubbing along herself once again. If she managed to get herself to climax before doing such a deed, nothing would be wrong, right? Her hooves pressed along her wet folds and parted them as she felt her clit give those familiar winks. She was getting so horny, though!

Her hind legs spread a bit while she thought about the colt's lap and traced her hooves around those sensitive folds. He would be so perfect to take, too. Just to arouse him and get him to really rut her like a stallion. Twilight moaned and clenched her hind legs together as she drooled a bit of her juices.

“Ms. Sparkle?” Rumble spoke up, tilting his head.

Twilight cleared her throat and sat up, unable to hide her blushing face to look at him while her forelegs stayed below the desk. Her ears perked up, doing her best to not appear guilty in her pleasures just out of sight.

“Yes? Wh.. Um, what is it?” Twilight asked, taking slow breaths and trying to not to lower her gaze below the foal's desk.

“Are you okay? You made a weird noise,” the colt asked and looked to her.

“I'm fine,” she replied quickly and slowly let her vision take in the small set of orbs and that young sheath once again. “Actually,” she started and bit her lip, hesitating. She really shouldn't, but it was such a good opportunity for her. “Come over here for a moment. I want to show you something..”

The words left her muzzle before she could even try to filter them. Her hooves pressed to her lap more as she looked down and noticed the chair glistening in her juices slightly. She was so wet for a foal! She would only get wetter once she heard Rumble's chair move and saw him begin moving across the room towards her.

The closer the colt got, the more excited Twilight became. Her eyes stayed wide open in desire as she watched him move up and stand before the desk between them. She could just tell him move around and then she would have it all on show for him. The alicorn knew better but it sounded so sexy to her. Every second was filled with how he might react to seeing an adult in such a manner.

“Around the desk,” she told him quickly and turned to the direction he started move. She had time to tell him to turn around or even keep some decency.

That was, until Rumble came around to her side of the desk and saw his substitute teacher leaning back in the chair with both her hooves between her hind legs. The whole moment had Twilight ready to pounce and grind the colt right there, but she wanted to savor him. Slowly, her hooves pulled away and her hind legs spread more, fully exposing herself to him.

The colt seemed surprised, to say the least, at a grown mare allowing herself to be seen in such a manner. Her wings were spread out with her hind legs trying to match. Those forelegs moved away to show the glistening sex to his young eyes and brazenly let him stare as much as he liked. The whole view made the young foal feel a little strange and unsure.

“I can teach you a much more fun lesson now that we're alone,” Twilight cooed and winked. “Go on.. Give your teacher a lick..”

The order had Rumble look a bit worried while he glanced back to the door. Was this his punishment? To lick a girl's no-no spot? He didn't like the idea of having to do such a thing. It sounded gross and he didn't see what could possibly be so fun about it.

“It's okay, I locked it,” the alicorn whispered, indicating the door. “A nice lick, Rumble.. Like your favorite treat,” she encouraged.

No movement forward came from the colt as he stood before her and frowned. The whole thing was sounding like a bad idea to him. He wasn't interested in doing a deed like she requested. Slowly, he started to step back with his ears pinned down.

“No, no~” Twilight said, magically pulling up the parchment from earlier. “I'll tell your teach just how uncooperative you were if you don't listen to me,” she threatens.

The young pegasus stayed still for a moment before he sighed and leaned forward, closing his eyes tightly. His mouth opened and his tongue slipped out as he inched closer to the heated and leaking loins of the princess spread before him. With his eyes shut, he had no measure of distance and quickly bumped his snout to that messy pleasure button as his tongue pressed along the slit below.

Twilight gasped out and put her hooves behind his head, holding him in place as her lower half quivered in such delight. The colt muffled surprise and some protest as she nearly smothered his face with her loins. The wetness coated his snout and muzzle, eagerly rubbing along his chin and forcing him to breathe in the scent of her arousal. She absolutely loved the feeling! Every small movement was amplified due to where his nose was buried on her.

The colt grunted and tried struggling away a bit while he had his face right in Twilight's crotch. Both of them squirmed but only one was due to pleasure. Rumble did his best to try and free himself from the hold she had on him but failed miserably, only able to get away from it all once his substitute teacher let go.

The two panted once she did release him, though. Twilight could feel herself growing needier by the second from that contact. Rumble was too busy trying to catch his breath before the alicorn magically lifted him up and laid him on his back.

“Not a word, or your teacher hears it all,” Twilight reminded him and hopped off the chair.

Unsure of what else to do, Rumble merely laid still for the princess and allowed her to do as she pleased to him. He didn't want a paddling from the teacher or possibly worse. He also didn't enjoy the smell on his nose but he was too scared to wipe it away.

Twilight moved down and planted small kisses to the foal's small chest and stomach, nuzzling a bit to him as she smiled. He was all hers and she could do exactly what she pleased for once. The thought made her slip a hoof back and press to her mound, rubbing the area carefully. She loved this.

The alicorn's head moved lower until she nosed at the tender sheath and marbles Rumble had nestled in his lap. The touch made him tense up but Twilight didn't halt. Her lips graced his lap in kisses as she planted them repeatedly over both nuts and even making out with his sheath. He tasted far better than she was guessing.

Every lick and tender nibble to the boy's lap had him whimpering and giving soft groans. Her mouth stayed busy upon his genitals, sucking on that tiny coin purse that held the two gems inside and tracing her tongue around the opening of his sheath. That hoof between her legs did its best to keep herself stimulated as she panted into the colt's lap with a lust she knew she couldn't keep under control.

Rumble struggled lightly but didn't try pushing her away, afraid of getting in any more trouble for the day. He never expected for his day to come out like this with him on his back and having an adult mare lick his little balls. It felt weird and he didn't enjoy any second of it. Somepony shouldn't be touching him like that, but she was older and he could get into so much trouble for not doing as she said.

Little by little, despite the colt's dislike, that young and tender shaft slowly began to emerge from hiding. Twilight took no time in lavishing it in licks and kisses.

Even though his body was being stimulated, Rumbled laid down before the princess, just wanting it all to be over quickly. Her mouth on his shaft had him wince from surprise at how it felt. It was warm and slightly pleasant but her lips and tongue moving along it kept giving him strange feelings below.

Twilight was in her own little world, suckling the colt's member and bobbing her head in his lap as she tasted how sweetly young he was. That delicate flesh ran along her tongue as she cradled it in her mouth, applying gentle suction and giving him, what she considered, one great blowjob for his age. Her eyes stayed closed as she just tasted his immature length, sucking the foal off and masturbating to her own act behind the desk.

Eventually, the noises her muzzle made on his lap began to get louder. The wet slurping and slick noises happened from every lift and lower her head made on his body. The colt squirmed, trying to just endure his 'punishment' for the evening as substitute teacher Twilight took her time in enjoying his underage body. Soon, her mouth pulled off his little, erect member with a small pop.

“Oh, goodness, you taste so good,” she breathed, licking the blunt head of his young cock and kissing all over it.

Slowly, the alicorn shifted and sat up, starting to crawl forward as she moved over the young pony. Her wet lap gave the lightest of brushes to that stiff and cute shaft below as she kissed Rumble's brow. The notion made him open his eyes, seeing the alicorn above him and wondering what was going on.

“I need it,” she whispered to him, clearly too far gone in her own lust to bother thinking rationally. “Let's make you a proper stallion~” she said lightly and smiled. “I want you in me..”

The two stared at one another for a moment longer until those purple hips lowered down, easing that young cock right up against those welcoming folds. The moist entrance of the mare parted as she pushed lower, slowly claiming little Rumble's virginity and gripping around his young shaft the more she move down. It brought her plenty of joy to see his eyes shut as those sensations ran along his body that she knew he'd come to enjoy some day.

Twilight moaned and pushed further, sinking the colt's length up into her until her wet grip rested right against him. He wasn't too big, but it felt just right for her. Even if he couldn't reach as deep a grown stallion, the mere act was getting her going far better than any stallion could. She couldn't believe how wet she was for a foal.

“Yes~” she groaned out, settled over him with her weight and panting lightly. “All mine,” she told him as she leaned forward and placed her hooves to either side of his head.

Without another word, her hips lifted and drew that colt cock from her body before she sat back down and moaned as she felt him slip back in. The two exchanged expressions while Twilight started riding the colt in the classroom, loving how good it felt to do such a deed.

Rumble seemed to be experiencing something, though he had no idea what. His forelegs lifted and gave small presses to the rising and lowering stomach above him. He didn't enjoy being used in such a manner, but speaking up might get him in more trouble. Instead, he merely tried to keep her from getting too rough.

“I love it!” Twilight called out, letting her wings flap to help a bit in her bounces on the foal. Her hips clapped to his smaller frame, enjoying the work. Soon, her hips began to be the only movement as she rode the colt eagerly, letting her juices drool and coat his lap from all the action.

The princess moaned louder as she worked her hips against the pegasus below her. Those purple thighs and lap pressing and grinding to him repeatedly in such hunger for the young. Her hind legs shifted a little as she spread herself and let her body press a bit more firmly into his loins, letting her tongue slip from her muzzle while she continued.

The very wrongful nature of the act added to her needs and wants, grunting every time she looked down between them, just to see his underage shaft being swallowed by her folds. Her pants became more erratic as she felt herself drawing close to her climax. The floor was getting just as doused as little Rumble was from those female juices.

More eager humps to the foal had Twilight grunting in need as Rumble squirmed quite a bit more below. His forelegs uselessly pushed at the mare atop him as he was used while his small member throbbed. All the new feelings that swarmed his body were unknown to him. He had never felt so..odd before.

The colt's mind tried finding ways to interpret the feelings, hardly knowing if they were good or bad. They were different for certain, but just in what way, his young mind couldn't comprehend. The only thing he could focus on was not getting in trouble. The small pegasus panted a bit and winced as he felt her press flush to him several times.

“D-don't tell! Please,” Rumble pleaded, having a hard time catching his breath.

“Oh~ I won't, cutie,” Twilight said, grinding a little to him as she felt her body getting closer to that wonderful moment she wanted so bad. “Just sit still and let Ms. Sparkle enjoy this for -ah- a little bit more!”

Rumble tried to think but it was too hard to focus with so many things going on with his body and the mare over him. He just wanted it to be over. Though, there was a new feeling rising very quickly within him.

Those lifts and drops against the small lap brought Twilight closer each time as she grunted and bit her bottom lip. Nothing would get her off like foals did. She knew that and she was perfectly happy with the fact. The forbidden lust was far more exciting the usual thing anyway.

“Ready, Rumble?” she panted out, riding him steadily and smiling down to the colt. “Ready to cum inside?”

Rumble had no idea what she was talking about but just gave a nod anyway. Anything to stop him from feeling so weird and having her privates touching his. He didn't like this one bit.

“Good boy! Ohh, such a good colt,” Twilight cooed and grunted slightly. Her hips rolled and worked that colt's prick inside her faster as she felt herself reach that wonderful brink.

The alicorn tensed up and gasped as she tightened along his beautiful, young cock. That marehood did everything it could to milk the colt inside as Twilight moaned loudly and leaned over the foal below. Her wings stretched out as she finally hit her mark and practically gushed into his lap. The orgasm hit her hard and fast, leaving her almost gasping while she came along the sweet length inside her.

Rumble had no idea what was going on or why the feeling along his privates changed and got more intense. It all went by so quick that he had no idea how to react. Then again, not like he properly could. The foal shuddered and lifted his hips uncontrollably as the two pressed their loins together. Then came the small squirt of immature seed into the princess above.

The little rope streaked those needy walls as they both climaxed. The white liquid dribbled and leaked out while his mind went blank for a minute as the mare accepted every little drop he managed to conjure up. While it wasn't much, it was more than enough to satisfy the foal loving princess.

Twilight shook and moaned, nearly groaning as her head tilted back to enjoy that cute spunk that squirted. He was far too young to produce a healthy amount, but it felt divine inside. Her inner walls gripped that cute shaft for a while as she bathed his lap in her love until she began feeling him soften.

The stamina for a foal wouldn't last long, though she had her fun. That purple body stayed settled on the colt as she panted and just waited a while. It felt so thrilling to have her way with a colt. Something she knew she'd get in more trouble with than Rumble with his antics in class.

“You were very good today,” Twilight said gently and kissed his brow. “I think I'll keep quiet to your teacher about earlier, okay?”

Rumble looked dazed but eventually nodded as he kept his gaze away. The princess smiled warmly and leaned over to lay against him very lightly as her wings moved to cover them both. She loved being a substitute teacher for foals. Maybe she could do it more often.

As she settled in for a moment, her magic did its best to readjust her mane into the bun from earlier. She would have to send him out soon or else questions might raise. Reluctantly, Twilight lifted up but only after a few more minutes of cuddling with the confused colt. Her body stood as she helped him up and began gently wiping him down to clean him up.

“There we go,” she said, trying to reach every spot, purposely rubbing his little lap more than she should. “Now, you don't say anything and I won't tell your teacher, right?” she asked.

Rumbled nodded and looked embarrassed as he stood there.

“Good! Now, hurry along and get yourself home,” the alicorn told him, ushering him out and unlocking the door for him.

As she cleaned up the rest of the room and let it air out, she couldn't help but think of when she might be able to do this again. Maybe Cheerilee might need a break sometime. Only time would tell.
