Please

Shining Armor was exhausted.

The weekend had finally ended, leaving him ripe and ready for the beginning of the school week to sink its teeth into him. Mondays were already the bane of any colt’s existence, but on top of that, Shining Armor had barely slept a wink the night before, too tense to ignore the churning, swelling nuts weighing heavily against his thighs.

They were even larger than oranges, now, and seemed to weigh more than a pound each. Each smack of those plump, weighty orbs against his legs or mattress sent an electric shock shooting up his spine—and a splurt of precum shooting from his flare. They’d gotten so big, stretched out by Shining’s cum production seemingly going into overdrive with every day that he failed to find release. A more lucid Shining might have guessed that every time he tried to rub on out, it only made the problem worse, adding his last orgasm’s cum to the future stores his grapefruit-sized orbs would grow to contain. But an even more lucid Shining would have known that it made no difference. He needed to cum, needed to find release more than anything he’d ever known.

Pent-up, tired, and frustrated at everything, Shining found that his morning was already going terribly. Unfortunately for him, it didn’t stop getting worse.

“Okay, everypony,” Miss Glimmerwing announced. “Put away your books and take out your quills. It’s time for the exam.”

The exam—the exam! Shining’s eyes shot wide open. Oh, Celestia. For all his time spent studying over the weekend, he found that he couldn’t recall even a single paragraph. Instead, the constant throbbing of his cock kept his thoughts spinning in circles, blanking out even the simplest academic knowledge.

As the teacher went around passing out exams, Shining realized that the filly next to him was staring at him—or, more specifically, at his crotch. Shining blanched when he realized where her gaze was directed. He hadn’t been soft in over twelve hours, now; his erection, far from going down, had stayed absolutely, completely hard, constantly needling him for attention. At one point, his tail at least had been able to cover his “needs” while he was walking. Sitting here in class, though, he was completely exposed.

Shining swallowed. Hearing a gasp, he glanced quickly over to the other side. Another colt—what was his name, again? Trend-something?—was staring at Shining’s massive erection with wide eyes and a hefty blush. At that exact moment, Shining’s balls throbbed between his legs. They were fat enough now that he had to keep his legs spread apart on his chair, and he knew exactly how visible they were to anypony nearby. It didn’t help, either, that the small river of precum constantly streaming down his shaft made his member slick and shiny with arousal, or that his stallion’s musk was rapidly spreading to highlight his lust for anypony within four yards of him.

Shining’s cheeks flushed. Hurriedly, he scooted himself a bit further under the table. His fat, puffy flare slid across the underside of his desk, slicking it with pre. He grit his teeth when he felt his stallionhood shoot out another glob of pre at the additional stimulation. It splattered against the table loudly, a fat gob of pre that left no mysteries as to the depth of his arousal.

By the time Shining’s teacher had made her way over, both of the other students had redirected their attention to their own desks. As Miss Glimmerwing set the exam onto his desk, Shining crossed his legs and fanned his tail out below him. He dearly hoped that she wouldn’t see the spreading puddle of pre below him, or smell the hefty plea for sex that his musk all but screamed for. Thankfully, she barely even glanced at him, though her nostrils did flare a bit at his scent.

As she walked away, Shining could almost swear that she was swaying her hips back toward him. He blinked, and the illusion vanished. A hard lump rose up in his throat. He had to clear his head, had to ignore his erection. He couldn’t go on like this. He needed to focus.

With a start, he realized that the rest of the class had already begun writing. Somewhat guiltily, Shining picked up his quill in his magic, dipped it into his ink bottle, and turned his exam over.

The first question. Right. He stared at it for a moment. Something about cell development. When he glanced back up at the clock, he realized that he’d been staring blankly at the page for nearly five minutes.

It was impossible to focus. The words blurred on the page, dancing, mocking him in their freedom. His eyes glazed over the page; each time he began to process a question, a throb from his cock, or the sloshing of his heavy balls, would instantly pull him out of it. His breath would shorten, his gut would clench, and his whole world would compact into that pillar of meat standing proudly at his crotch.

Even the white—the creamy, simple white—of the paper set him off. He found himself lost in a reverie, imagining stripes of that thick white overlaying a mare’s flank. Dripping from Cadance’s muzzle. Leaking, drooling from the wide-stretched petals of Twilight’s once-virgin fillyhood.

Shining swallowed again. His cock lurched beneath the table again. The pressure inside of his balls was unbearable. He was twitching, sweating; his hoof was trembling, even flinching with each new throb of his shaft. As the rate of pre pouring from his aching member redoubled, Shining’s horn glimmered. Unconsciously, helpless in the face of his baser desires, his magic began to caress, to stroke, to squeeze his organ as it begged for attention.

Somewhere in the back of his mind, he registered the disgust on the face of the filly beside him. She could see his bright blue magic wrapped around his tool, fondling it, stroking it up and down. But Shining didn’t care. His lip trembled, his thighs flexing as he slipped into self-pleasure. He needed this: needed to jerk himself off, to find release. But it wasn’t enough.

It was never enough.

After an eternity, the bell finally rang. Shining sat, glassy-eyed, shaking slightly, as the teacher went around to collect their tests. He’d filled out barely a third of the answers. Somehow, though, the reality of that seemed so far away.

The second the teacher’s magic scooped up the papers from his desk, Shining was gone. He darted from the classroom, panting, his member smacking wetly against his belly. He didn’t know where he was going, but he knew that he had to get somewhere alone—somewhere where he could take care of himself properly, and who cared if it would do no good? Who cared if it would just make everything worse? He needed—he needed—he needed—

Twilight.

He blinked. Was that—

But no. She was too tall; her coat, not nearly purple, was pink instead. A soft, welcoming pink. The candy-color streaks in her mane, while reminiscent of Twilight’s, were pink and yellow. And she was too tall, too old, too—beautiful.

His mouth went dry.

“Shiny!” Cadance beamed at him. Shining twitched; he couldn’t go around her. The crowd in the hall was too thick, and she was all but barring his way. “How was your weekend?”

“My—my weekend?” Shining stammered. Below him, he felt his cock lurch against his belly. A fat puddle of pre was already beginning to spread across the floor beneath him. His tail swished behind his hocks. With a dawning sense of horror, Shining realized that his balls were officially too big, too round, too full to be covered up. His legs were set wider apart, forcing him into an almost waddling gait. A muscle twitched in his thighs, forcing his hind legs back together and squeezing his plump, cum-laden orbs between them for a moment. Shining stifled a moan, and another glob of pre spattered noisily against the floor.

Oh, Celestia. Everyone could see him. Everyone could see his arousal—could see how pent-up, how fucking huge his nuts were. Oh, gosh, but the mess he was making everywhere—the lakes and rivers of precum he’d been dribbling all over the school. Oh, Celestia, but Cadance was going to notice, and she was going to ask, and she was going to make him tell her what was wrong—

She was still staring at him, he realized. And she hadn’t even glanced down, hadn’t seen the fat, black flare throbbing between his legs. Forcing a smile onto his face, Shining chuckled uneasily and took a step forward.

“Oh, it was—good,” he said. “Lots of, uh, studying.”

“Studying, huh?” Cadance’s eyes lit up. “Oh, for the biology test? How do you think you did?”

“O-okay.” Shining’s front knees were starting to knock together. The drool of pre from his tip had doubled again. He had to bit down on his lip to keep from groaning. The tightness in his nuts almost hurt—but, at the same time, he longed to massage them, to squeeze them, to caress them. He wanted to feel the cupfuls of seed sloshing around inside of their cum-laden depths. He wanted to let the pre spurt against his chest, wanted to cradle his aching balls, wanted to imagine releasing their enormous load inside of Twilight’s—a mare’s tight, warm cunny.

“...So,” Cadance finally said. She grinned lamely at him. “Did you want to maybe hang out later? We can go to the library and try to get some homework done together. Or go to that new cremerie downtown.”

Shining gave her a nervous smile. “I’d love to, really,” he said. “I just, uh, have other things to take care of.” He didn’t want her to see him like this. She couldn’t know—he couldn’t let her find out what he was thinking, what he wanted to do.

Oh, Celestia, what did he want to do?

“Oh.” Cadance’s smile faded a bit. “Sure. Maybe tomorrow, then?”

“Maybe,” Shining blurted. The pressure in his balls was swelling to a peak. He could actually feel the skin around his nutsack tightening, stretching as more and more jizz filled his sore, overstuffed nuts. “I—look. I gotta go.”

“Oh,” Cadance said. “Sure. Just...let me know, okay?”

“Got it.” Shining’s hooves were tapping frenetically. He needed to escape, badly. “Right.”

Cadance brightened. “Oh! And if we wind up doing anything, you can bring Twilight. I’m sure she’d love to try some of their ice cream.”

The image came, not entirely unbidden, into Shining’s mind’s eye: her muzzle, white and splattered with cream. But was it a sweet dessert...or was it his cream that she’d just been eagerly guzzling down?

Shining froze. His heart feeling like it was trying to leap up his throat and choke him, he lowered his head and shook it vigorously. “No!” he blurted. His balls were swelling even further; he felt like they were going to blow. And why wouldn’t that image of Twilight leave his head: Twilight, her cute filly cheeks puffing out around his cock, the sound of her steady gulps music to his ears as she swallowed cupful after cupful of his cum, her small filly’s tummy steadily swelling out with his seed…

He couldn’t take it anymore. Without another word, he galloped down the hall, rudely pushing Cadance aside with his shoulder. The last thing he saw of her was her wide-eyed, shocked expression—and then he was blurring down the corridor, his mane whipping behind him. Panting, searching desperately, he finally found what he was looking for: the colts’ room.

Shining burst into the bathroom, sending a lanky colt spinning in his wake. He crashed into a stall and slammed it shut behind him with his magic a fraction of a second later. Gasping, he propped one foreleg against the wall and leaned his weight against it. Once he’d angled his huge, throbbing member over the toilet, he took his other hoof and went to town.

His every breath felt like it shook his body. Shining’s lungs heaved, his whole torso trembling with the strain of the pressure he felt in his nuts. And just like that, something broke.

Shining Armor gave up.

Images of Twilight flooded his mind. Jerking him off, sucking him off, playing with him, teasing him. He imagined slipping inside of her while reading to her, and a sickly grin crossed his face. He imagined pinning her to the carpet and fucking her while she cried out and groaned in absolute pleasure. He imagined stretching her wide around his cock, plunging his girth in and out of her as she begged for more.

Shining’s hoof sped up and down his shaft, stroking it firmly as his magic teased and plumped his balls until they felt ready to explode. He was still panting, even as glob after glob of pre drooled from his hefty flare, spilling down into the toilet.

He couldn’t deny anymore—he wanted, needed to rut Twilight. To make his little sister his mare. To spear her on his cock, to fill her up with his spunk, to watch her belly bloat around his length as her womb filled up with every drop of his hot, churning seed.

Shining bit down on his lip so hard that he actually broke the skin. He couldn’t help it; after being suppressed for so long, every one of his depraved thoughts were flooding back into his mind, driven entirely by the roaring force of his bestial libido. He could see them now: her cute filly lips, winking slightly, dripping with her honey as she welcomed him inside. He could see her cheeks bulging around his cock, his hoof sliding gently down her neck as he pumped his girth all the way back to her throat. He could see his flare bulging, stretching her neck as he pumped an impossible amount of cum down straight into her belly.

He felt it again: that familiar feeling of tightness and pressure building in his loins. By now, he’d grown to dread it almost as much as he loved it. Maybe this would be the time when he finally came, he told himself. He knew what he wanted—didn’t he? He wanted Twilight. He wanted Twilight, in a way that any stallion wanted a mare. And as he felt his balls churning, swelling, producing more and more cum to deposit into Twilight’s perky little butt, he knew that he would finally find release.

Except he didn’t.

Shining Armor collapsed against the wall. Only the sudden jerk of his hoof stopped him from slamming into the toilet seat. His chest heaving, and sweat dripping down his chest and chin, Shining watched with a dull horror as his hips bucked—only to release a huge glob of milky-white pre into the bowl. Not a drip of cum escaped his tip, though his fat flare throbbed for it.

He slowly slid down until he was squatting on his haunches. His member bobbed out before him, still drooling pre onto the growing puddle on the floor. He’d actually made the toilet bowl come close to overflowing, and yet he felt no closer to the satisfaction he’d so craved. Shining actually whimpered, feeling his balls fill up bigger and plumper and heavier.

Where would it end? he wondered. When they draped down halfway to his knees? When the slightest touch would send him careening with the force of an almost-orgasm? When he could barely sleep or eat or breathe, too consumed by the sloshing, the roaring, the never-ending churning of his overstuffed nuts to even think? When they were big enough to drag along the ground? When they were too big for him to walk? When they were so big that his tortured, stretched nutsack just finally gave up and burst?

And then, just like that, Shining Armor knew the nature of his curse.

He blinked slowly, his eyes glassy as the thoughts stirred in his mind. Like a pool in the wake of a ripple, his thoughts suddenly stilled, focused only on one idea. It surged up into his skull, grabbing every available process and forcing them into a single, distilled thread.

It can make a stallion do anything you want.

A stallion.

Anything you want.

Make him do it.

It can do it.

The spell.

Shining’s lips curled. He felt like laughing, and he felt like crying. Of course. Twilight’s spell had done this. Her teacher’s “special book?” He had a fair idea of what that was now. Not that it made much difference, now that he’d been pushed past his limits.

His chest slowly rose and fell. Shining suddenly knew one thing, and one thing alone: He had to get Twilight to lift the spell. To cancel it, to summon up a counterspell, anything. But to get her to do so…

Shining almost gave a bark of laughter. She wanted to know about “the Talk?”

He’d tell her. He’d show her. He’d make sure she’d enjoy it, thoroughly. And he’d finally be able to enjoy his release. She would be willing to help him, he knew. He was sure of it. He would ask her—beg her, if necessary. She was his little sister—she loved him. And he loved her. He loved her more than anything.

By the end of this, he would make sure that she knew that.
