Sweet Apple Discipline

Rarity looked at the three girls, and admired her work. Rope wasn't her usual artistic medium, she thought, but she had outdone herself. In their own way, the three girls agreed.

Not that they were happy about it.

Apple Bloom, Sweetie Belle, and Scootaloo all stood in the middle of the barn, naked, sweating and squinting under the heat of the four interrogation-room lightstands mounted in front and behing them. Their arms were tied behind their backs, bound at the wrists and elbows, with a rope at the wrists rising to the ceiling in a cruel strappado that kept their hands lifted a foot and a half above their heads. They all had a length of twine tied around their left toe attached to a harsh clamp on their right nipple, and on the right toe attached to their left nipple, shortened to keep them hunched forward in a painful squat and stop them from standing straight to ease the strain on their shoulders. Each of their bare feet rested on an overturned milk-crate, which they occasionally tip-toed on in a desperate attempt for relief, and a yard-long spreader bar was cuffed to each of their ankles to stop them from easing the strain on their nipples by bringing their legs together.

They couldn't protest, though. Mostly because they had each been gagged with their own panties, sealed into their mouths with a piece of duct tape.

Rarity lit her cigarette, took a drag, and exhaled. "I hope you three know why this is necessary."

She heard only muffled cries in response. Her little sister looked at her imploringly. She was unmoved.

"Your last stunt wasn't simply irresponsible, it was dangerous. You're all lucky that nobody was permanently injured, and you all knew better from the start. Now, I'm sure you're aware, you're not little kids any more, you're young ladies, and you're too old for a spanking. Young ladies, after all, do not get spanked."

She narrowed her eyes. "Young ladies get fucked. Oh Macintosh! They're ready!"

The Cutie Mark Crusaders whimpered as Rarity walked off into the darkness, and Big Mac stepped forward.

He was naked.

He was built.

And his nine-inch shaft was achingly hard.

Big Mac stroked his cock as he walked around the bound, sweating teenagers, inspecting them closely.

Apple Bloom couldn't meet his gaze, her orange eyes glassy, blinking back tears. He rested a thumb on her cheek, running it over her cute freckles, before brushing a strand of her soft, red hair out of her face. With the same hand, he reached down and grabbed one of her nipple clamps, twisting harshly. She squeaked into the gag and shook her head, eyes squeezed shut, but didn't dare resist on such precarious footing. The milk crates under her feet didn't feel sturdy at all...

He let go of the clamp, but continued to feel her breasts. They were small - bumps compared to her older sister's lush rack - but not quite flat, just enough for Mac's hand to grope and squeeze. His hand travelled down and snaked between her legs, rubbing roughly at her pussy. Rarity had taken care of the hair down there, not that there was much to begin with, so her ran his fingers over her smooth crotch before returning to her twat. He spread the lips with two thick fingers, feeling the sinfully soft flesh yield underneath them, rubbed up and down from the clit to the bottom, and rubbed them in circles at her entrance, feeling only the slightest hint of moisture.

Apparently, being finger-fucked by her brother wasn't a turn on.

As he continued to rub her, he caught a glimpse of her armpit, also hairless, beads of sweat shining in the light. He pushed his head down and licked it, a light taste of salt on his tongue as he lapped up the sweat, with the slightest spice of body odor. He did the same to her other armpit, then withdrew his fingers, and walked around her.

He grabbed her ass in both hands the moment he saw it. It was still underdeveloped, nowhere near as proud and firm as Applejack's incredible booty, but it was round, bouncy, and jiggly, with the firmness and allure of an almost-ripe fruit. He spread her cheeks, pulling her pussy wide and displaying her tiny asshole. He couldn't tell which target looked more delectable.

Apple Bloom cringed as her brother spat on her ass-crack.

Mac pushed his fingers into the blob of spit and rubbed it up and down her crack. Her whole body stiffened as he pressed a slick middle finger against her pussy, and kept pushing. Even a single one of his thick fingers was painful, and as he pushed it in up to the second knuckle, a wave of prickly, nauseating heat crawled under her skin. It was too dry to slide in any further, but instead of adding more lubrication, he twisted it from side-to-side, pushing upwards until it was all the way in, to Apple Bloom's pain and discomfort. It was tight and hot clamped around his finger. He could barely imagine how she'd feel wrapped around his dick.

He withdrew his finger and sucked it clean, tasting her sweet, musky juices, making sure to leave his finger covered in spit. Then he reached back down and pressed the same finger against her anus. She whined into the gag, almost hyperventilating as the blunt tip of his finger spread her open. The heat alone was incredible, hotter than her unaroused pussy by a long shot, and her desperate attempts to clench down and deny him entry only made it tighter. She couldn't help but twitch and wriggle as he forced his way in. He considered testing her anus with a second finger, but decided to move on, pulling his finger loose and wiping it clean in her hair.

Scootaloo glared at him hatefully as he approached. He'd have fun with this one. He grabbed a fistful of her short, purple hair, almost hard enough to tear it out, and slapped her face with his other hand, light and sharp and over and over and over until her cheek was as red as Apple Bloom's hair and she was squealing through her gag, tears running down her face. Next, he felt her tits, though they could hardly be called that. He could have used her chest as a pool table, for how flat it was. He settled for flicking and pinching her pebble-sized nipples underneath the clamps, before reaching down to grope her hairless cunt.

More than a hint of moisture coated his finger. The corner of his mouth twitched up into a smile.

After wiping the finger under her nose, he walked behind her. To call Scootaloo's ass 'boyish' would have been generous. There was hardly enough flesh between her back and her legs to pinch between two fingers, just the tiniest bump of lean, athletic muscle. He reached under again and felt her pussy from behind, rubbing it slowly. He slapped it a few times, causing her to yelp and try to stand up from her enforced squat, and yelp again as the twine between her toes and nipples went taut and yanked her tiny tits. Once again, he pressed his middle finger to her pussy, but this time it slipped inside, slowly but surely. She moaned in humiliation, unable to repel the invader, her wet, tight, and burningly hot hole only serving to invite him in further. A thought struck Mac, so he reluctantly pulled out, and turned to the leather bag of goodies that Rarity had left out behind the three girls. He took out a bottle of lube and a butt plug, and turned back.

Kneeling down behind Scootaloo, he coated two fingers on both hands in lube, and spread her tiny butt cheeks again. He pressed both of his index fingers against her slit, and both of his middle fingers against her tight little rosebud. Her muffled protests at having her ass and pussy simultaneously invaded were ignored, and he pushed on forward, slowly but surely, ignoring her wriggles and discomfort until all four fingers were three-knuckles-deep. He luxuriated in the twin sensations of her cunt and ass. Her ass was definitely tighter, but her pussy radiated incredible heat. A difficult choice.

He played around with her a while longer, trying to pull his hands apart to stretch out her two holes until he could see into them. He got about an inch of space in each, and some interesting noises from Scootaloo before he stopped and pulled his fingers out. He lubed up the small plug and worked it into her ass, much to her displeasure, and stood up, making sure to wipe both of the fingers that had been up her ass under her nose before he walked away.

Sweetie Belle was, in his opinion, the cutest of the bunch. Between her lush, curly hair, her clear green eyes that begged so pathetically for freedom, her pert, squeezable tits, her soft thighs and belly that still bore the traces of puppy fat, and her jiggly, over-fed butt, she was downright irresistible. The thought of hurting her made Mac's cock twitch longingly. As he groped and pawed her, licking the sweat off her tits and neck, an evil plan grew in his mind.

He returned to Rarity's bag and took out a box of clothespins. Rarity had them custom-made, with triple-strength springs. They would do nicely. He began to cover Sweetie Belle in clothespins, each one pinching down on her soft, pale skin. He pinned half a dozen on each of her tits, pinned them all over her belly, on her armpits, on the skin of her upper arms, on her butt, all over the sensitive flesh of her inner thighs, pausing only to wipe a bead of precum off his cock and rub it onto her clit. He continued on her face as she whimpered into her gag, one on the side of each nostril, three along each of her eyebrows, on her cheeks, under her chin, half a dozen on each ear until it looked like she was wearing a bizarre fetish-mask of spring-loaded wood.

When he knelt behind her, he saw something that made him smile again: a small, thin vibrator buzzing away on 'low' in Sweetie Belle's juicy twat. He pulled it out just so he could inspect it freely. Unlike the tight, tucked-in lines that were Scootaloo's and Apple Bloom's snatches, Sweetie Belle's pussy was puffy, pink and almost swollen, a flower drenched in nectar. To Mac's surprise, she was as tight as Scootaloo, sucking his finger in as he pushed it into the slick, warm hole. He put seven more clothespins on her - three each on her labial lips, one on her clit, the last enough to make her break down crying.

Mac couldn't think of any way to easily put a clothespin on her asshole, so her settled for taking a tube of mint toothpaste and pushing a thick blob of that past her ring, where the menthol would cause some interesting sensations on her sensitive membranes. He pushed the small vibrator back into her cunt, this time on 'high.' Lastly, he took the two lengths of twine that connected her toes to her nipples and forced her into a squat, and shortened one by a few inches, making her distribute her weight unevenly to the left side of her body, causing even more aches and strains.

He stood up, his inspections complete. His cock ached, desperate to plunder some tight, teenage cunt, and he was ready to let it do just that.

Then Mac felt a pressure in his bladder. He sighed. Then, an idea.

He walked behind Scootaloo and pulled out her buttplug, earning a stream of muffled swearing and loathing, which climbed significantly in pitch as she felt him force the plum-sized head of his cock in its place. Her nostrils flared as she breathed through her nose, frozen in panic as Big Mac stopped moving behind her, praying he wouldn't force his cock any deeper. He didn't, and had no plan to do so.

Instead, he began to piss.

Scootaloo boiled with a mixture of shock, disgust, and misery as Mac used her as a literal toilet. She felt the hot liquid swelling up inside her, making her guts cramp, sending stiches of pain through the muscles in her torso, his hot breath on her neck as he sighed with relief. Nothing she could do would stop him. Even moving away from him would only tighten the strappado and likely dislocate her shoulders. He must have filled her with a full pint already, and the stream was still going strong. Her guts churned as if she were sick with stomach flu.

Finally, the flow cut off. Scootaloo looked down, whimpering, and saw the slightest hint of a bulge in her belly. She screeched in pain as Mac shoved the buttplug back in, a split-second after withdrawing his cock, with only a small trickle of yellow piss escaping and running down her thigh. He wiped it up in his hand and rubbed it on her face, and then walked away to stand in front of the three.

He folded his arms, cock standing to attention below, and looked between his humiliated sister, the degraded daredevil, and the clothespin-covered singer. They looked back at him with varying measures of loathing, trepidation, and disgust.

He grinned. "Who's first?"
