--It was a beautiful day in Ponyville, and the fillies and colts from Cheerilee’s class were playing outside on the recess. Scootaloo was performing tricks with her scooter, showing off her skills and enjoying the attention. It was the closest she could get to feeling like Rainbow Dash, and with how much she used her scooter she felt as familiar with it as her idol must have felt with her wings.
”Now watch this!” Scootaloo said confidently, lining her scooter with a makeshift ramp her friends had constructed. She took off, buzzing her wings for speed, hitting the ramp and launched herself into the air. With flawless accuracy, she landed her scooter on the backrest of a bench, riding it to the end on two wheels before landing safely on the ground.
”Woohoo! You rock!” Crackle Pop cheered. The grey little colt jumped up and down with excitement as Scootaloo casually rode her scooter next to him.
”Oh that? That was nothing.” she said with mock modesty. ”Just something I picked up on the way to school.”
”Can I try?” he asked.
Scootaloo was surprised. She didn’t know that Pop - or anypony else in the school for that matter was into scooter tricks. ”Are you sure about that?” she asked cautiously.
”Sure!” he answered. ”I used to ride a scooter all the time back in Fillydeplhia! It would be great to try it again!"
Scootaloo was still a little vary, but relieved to hear he had at least some experience. ”Okay. But be careful with it!” she said, stepping off the scooter and handing her helmet to him. Crackle Pop wasted no time strapping it on and getting on the scooter, riding a few loops around the playground to get used to its handling.
Scootaloo smiled as he picked up more speed, clearly enjoying himself as the muscle memory was quickly returning to him. To her surprise, he soon lined himself up with the ramp and started accelerating towards it confidently.
”Um, are you sure about this?” Scootaloo asked nervously, but Pop was too focused on repeating her stunt to listen. She could only watch as she hit the ramp just like she had, but in mid-air his rear legs came off the scooter as it swung out of control to the side. His eyes went wide as he plummeted straight on top of the backrest, hooves slipping around it as he slammed balls first onto the wooden beam.
”GYAAH!” he screamed in an uncharacteristically girly voice, eyes bulging even further as his body tensed up. Scootaloo couldn’t help but burst in laughter at how ridiculous this was coming from somepony who professed to be an experienced scooterer. He didn’t so much get off the bench as slid off, his entire body still stiff as a board and face like he’d just seen a ghost.
”Hahaha! Oh man, you should have seen your face!” Scootaloo laughed, trotting over to him.
”My balls...” Pop whined softly.
Scootaloo could only burst into another fit of laughter. ”Your balls? What about them?” she asked, already looking forward to what he had to say.
”I... landed on my balls...” he half whispered, gasping for air with his forehooves cupped protectively over his groin.
Scootaloo fell over laughing. She had taken many falls and bumps like that while practicing, but she’d never been that out of shape even after a full-speed crash. Yet here was a tough colt moaning over a bump too minor to even make a bruise!
His groaning and moaning were interrupted as the school bell rang, signifying the end of the recess and seeming to snap him out of his balls-induced trance. ”Oh no, please don’t tell Miss Cheerilee! I don’t want her to know I was being reckless again!”
Scootaloo was still laughing, but stood up and offered him her hoof. ”Sure thing Pop. I wouldn’t want her to know I let someone crack their nuts on my scooter either!” she said with a chuckle. She helped him up, smiling as the colt hobbled inside, trying his best to act casual despite waddling awkwardly with his rear legs wide apart.
The rest of the school day went uneventfully, but Scootaloo just couldn’t get that colt out of her mind. She kept playing the scenario over and over in her head, smiling as she remembered how just bumping his nuts a little had completely knocked out literally all of his dignity. She couldn’t wait to tell about this to her friends, and when the bell finally rang, she was first out of the class and waiting for them.
”Hey Scootaloo! What’s up?” Sweetie Belle asked as she exited the schoolhouse with Sweetie Belle.
”Did you see Crackle Pop falling on the backrest last recess?” Scootaloo asked with barely contained enthusiasm.
”No, I just saw him scootering around.” Sweetie said. ”Why? What happened?”
Scootaloo spent no time getting to the good parts of the story. With some minor embellishments, she told about how he had basically fallen from standing height and then screamed about his balls in the most ridiculous voice imaginable. The other crusaders looked at her with expressions turning from curious, to surprised, and then disbelieving.
”Come on Scoots, Crackle Pop isn’t a crybaby!” Apple Bloom said.
”Yeah, that sounds just wildly implausible.” Sweetie Belle agreed. ”Boys would never play tough and tumble games if they were that sensitive!”
”Come on, it’s true!” Scootaloo swore. ”Their balls must be like some kind of magical shutdown button!”
”Well that should be easy to test.” Apple Bloom said, looking around and spotting one last colt leaving the schoolhouse. ”Hey Chipcutter! Wait up!” she yelled, running up to the grey colt and waving for her friends to follow her.
”Oh hey, what is it Apple Bloom?” Chipcutter asked with an unsuspecting smile.
”We need to test something.” Apple Bloom said. ”Could you stare at Sweetie Belle for a moment?”
”Oh? Allright.” he agreed with mild confusion, turning to face directly at her. Sweetie Belle grinned awkwardly at being put in a spotlight, but luckily Apple Bloom was already moving behind the colt and lining up for a buck. She lifted her leg and took careful aim before kicking, her hoof striking him in the balls perfectly and flattening them against his pelvis with an audible thump. In a split second, his eyes went unfocused and his jaw dropped, his legs buckling as he fell with a high yet guttural scream.
”AAAGH! My balls! Oh Celestia my balls! Owww!” he wailed, clutching his groin and rolling back and forth on his back. Apple Bloom and Sweetie Belle stared at him with surprised disbelief, while Scootaloo grinned widely and looked back and forth between her friends and the fallen colt.
”See?! That’s exactly how Crackle Pop reacted!” she said, beaming with pride as her friends admired Apple Bloom’s hoofwork.
”That really worked?” Apple Bloom asked with disbelief, looking down at the colt she’d just brought down. ”I barely even touched them!”
”I know, right?” Scootaloo smiled. ”Boys basically turn into babies when anything touches their privates.”
Sweetie Belle was less enthusiastic about the revelation than her friends. ”I don’t know about this...” she said. ”It looked like it might really hurt.”
The other two crusaders blinked thoughtfully. ”Well how are we going to find that out? We know we won’t get a honest answer from him.” Apple Bloom said, gently prodding the whimpering colt with her hoof. ”Oh, I know!” she said cheerfully ”I’m gonna pick up some supplies and we’ll meet at the clubhouse, okay?”
”Okay!” her friends agreed, watching as Apple Bloom took off at full trot. Whatever she had in mind had definitely piqued their interest.
Later that day, the three fillies met up at their clubhouse to hear out Apple Bloom’s plan. She had brought a saddlebag with her and was already unloading its contents on the floor as her friends walked in.
”Hi Sweetie! Hi Scootaloo!” she waved excitedly.”
”Hi Apple Bloom. So... how did you plan to learn about colts from here?” Sweetie Belle asked.
”That’s easy! Remember our sex-ed class?” Apple Bloom asked. Sweetie Belle nodded, still unsure of what she was going for. ”Cheerilee taught that despite looking different, penises and vaginas are made of from basically the same parts!”
Sweetie Belle recoiled at the realization. ”You don’t mean we-”
”Yep! We can just buck each other in the coochie and it should be basically the same thing.” Apple Bloom confirmed proudly.
”But what if it really hurts?” Sweetie Belle protested, remembering the reaction of the poor colt Apple Bloom had bucked earlier that day.
”That’s why I brought a first-aid it, just in case.” Apple Bloom said, gesturing towards the things she had prepared. ”Band-aids, heat-rub, comfort food...”
”What’s that?” Scootaloo asked, pointing at a soggy, sealed-up bag.
”It’s an ice pack. Or at least it was before it melted.” Apple Bloom said sheepishly.
”Alright, this looks like a great plan! ”Scootaloo agreed. ”Turn around and lift your tail - I want the first buck!” she said enthusiastically.
”What? Why me?” Applebloom asked.
”Because it was your idea.” Scootaloo reminded.
”Fine.” Applebloom agreed, getting in position. She was pretty sure about herself, but being put on spot like still got her a little nervous.
”Okay, here it comes!” Scootaloo said, lifting her hoof off the ground and kicking back. Applebloom let out a yelp as the hoof struck her groin with an audible smack, standing in place as her friends moved to her sides to check in on her.
”Well, it definitely wasn’t bad at all.” she said after pondering the feeling for a minute. Her friends let out a sigh of relief. ”Try again Scootaloo, harder this time.”
Scootaloo turned back behind Applebloom and prepared for another buck. ”Ready Applebloom? Here it comes!” she declared, bucking hard enough to send the earth pony stumbling forward to maintain her balance.
”Ow!” she yelped a little louder this time, rubbing her rear with her hoof for comfort.
”Are you okay? How bad is it?” Sweetie Belle asked, trotting closer.
”It hurts, but definitely not too bad. Kind of like getting punched in the shoulder.” Applebloom replied, giving her nethers a few more gentle brushes with her tail before turning around.
”Really?” Sweetie Belle asked incredulously.
”Yeah, really!” Scootaloo chimed in. ”I’ve gotten quite a few bumps down there while practicing scooter tricks - it’s annoying, but definitely nothing like the colts make it look like! Here, try me.” she said, turning around and exposing her pussy.
”Uhh, sure." Sweetie belle blushed at the promiscuity of the situation, but she did want to confirm the matter for herself. She turned around and got into position, bucking Scootaloo straight in her pussy.
Scootaloo gasped, but other than that barely even flinched. ”Come on Sweetie! Don’t hold back!”
Sweetie Belle took aim again, bucking back with all her might. Scootaloo’s rear legs lifted off the floor as she gasped again, sucking air between her teeth as she turned around brushing her tail over her plot. ”Good job Sweetie Belle! That one actually smarts a little!” she said with a proud smile.
”Okay Sweetie Belle! Your turn!” Apple Bloom chimed in.
”Um, do I have to?” Sweetie Belle said nervously, backing slowly away from her.
”Sure! You’re the one that wanted to know how it felt in the first place, weren’t you?” Apple Bloom asked, gently laying her forehoof on Sweetie Belle’s shoulder.
”Yeah, but, um...” Sweetie Belle stammered. It would indeed be hypocritical of her not to put her bits where her mouth was. ”Fine, I’ll do it.” she agreed, turning around and exposing herself to Apple Bloom. ”Just don’t buck too hard, okay?”
”Okay. Here it comes!” Apple Bloom said, bucking Sweetie Belle right between her flanks. She let out a squeal as Apple Bloom’s hoof smacked her on the marehood, jumping a little at the shock of the impact.
”That was it?” She asked incredulously.
”Yep.”
”But that hurt less than falling from a chair!”
”That’s exactly how hard I bucked Chipcutter.” Apple Bloom shrugged.
”Wow... I guess colts really are oversensitive about their privates!” Sweetie Belle said with astonishment. This revelation was changing everything she thought she’d known about colts.
Apple Bloom cleared her throat for an official cutiemark crusader declaration. ”So, in the light of our latest discoveries, I propose we head out and perform more experiments about bucking colts in their testicles!”
”Aye!” Scootaloo and Sweetie Belle agreed in unison. ”Cutiemark Crusader Ballbusters, YAY!”
Giggling with excitement, the trio of fillies ran out of their clubhouse to seek out colts to play with. They had barely made it out of the orchard when they spotted Rumble flying high in the sky.
”Rumble! Hey Rumble! Over here!” Sweetie Belle called, waving for attention.
Rumble swooped down, landing gracefully right in front of her. ”Hey Sweetie Belle! How’s it going?”
”Great!” she chirped happily. ”We just learned a great new trick - wanna see it?”
”Sure!” Rumble nodded.
”Okay. Turn around and close your eyes!” she instructed, twirling her hoof in the air for emphasis.
”Okay.” he agreed and spun around, waiting for Sweetie to tell him when to open his eyes again. Instead, his eyes shot open in an instant as her hoof smashed hard into his balls.
”YAAGH!” he yelled, dropping like a sack of apples and clutching his balls in agony.
”I did it! I did it!” Sweetie yelled happily as she bounced in place. ”How’d you like it?”
”M-my balls...” Rumble whined, shuddering in place and gasping for air.
Apple Bloom laughed. ”That’s exactly what Chipcutter said too! Hey Scootaloo, how long does this last?”
Scootaloo rubbed her chin, thinking back to her first experience in the school playround. ”I don’t know, maybe half a recess?”
”Well we don’t have time for that. Let’s go find more colts!” Apple Bloom said enthusiastically.
”Sorry Rumble!” Sweetie Belle giggled, petting his head in a belittling manner. ”That was just too funny! See you later!” she finished and ran off with the rest of the crusaders, leaving Rumble to nurse his balls in utter confusion over what just happened.
It didn’t take long for the trio of fillies to come across another unsuspecting colt.
”Hey Carrot Crunch! Wanna see something cool?” Apple Bloom yelled, running ahead of the group to greet him.
”Hi Crusaders!” he greeted back happily. ”What is it?”
”It’s a neat little ball-trick we just learned about. Would you mind turning around for a while?”
”Okay." Carrot Crunch said and started turning, before quickly yanking his tail down as heturned back to look at her with suspicion. ”Wait a minute... You’re not talking about my balls, are you?”
”Mmaybe?” Apple Bloom answered, failing to hide her smirk as she did.
”Oh no, no way!” Carrot said, shaking his head. ”You were going to hit me in the nuts, weren’t you?”
”Come on, it doesn’t hurt that much!” Scootaloo piped up.
”Does too!” he said, closing his legs at the sheer mental image.
”Nu-uh! Here, I’ll show you!” Scootaloo said, turning around and exposing her pussy to him. She looked back, smiling as she saw his gaze fixated to her rear end. ”Go on, buck me as hard as you can!”
He swallowed hard, unable to look away as Scootaloo swayed her hips seductively. ”Um... could I just... feel it a little? And then I’ll let you feel me too?” he suggested awkwardly, eyes still nailed to Scootaloo’s marehood.
”Sure! That sounds even better!” Apple Bloom answered before Scootaloo, eagerly trotting up to her side. ”Come on Sweetie Belle!” she called, gesturing for her to follow as well.
Carrot could only watch with mouth agape as Sweetie Belle shyly got up to Scootaloo as well, pressing against her side opposite to Apple Bloom. This wasn’t what he had expected, but with three fillies exposing themselves to him flank to flank, he could barely believe his luck. Gingerly reaching up at Scootaloo’s pink little slit, he carefully prodded her labia with the tip of his hoof. Scootaloo’s raised tail twitched a little, prompting him to gently press the bottom of his hoof against it.
”Oh wow...” he muttered, breathing heavily as he lowered his hoof to move it over to Apple Bloom. She giggled softly at how shy the colt was, his hoof barely grazing over her marehood.
”You can spread it if you like.” she hinted, stepping backwards a little to encourage him.
”Okay.” Carrot Crunch nodded, lifting his other hoof to fondle her too. Looking right into her pussy, he suddenly noticed his cock was already rock hard and throbbing for attention. He dropped one hoof to casually stroke it while also turning to study Sweetie Belle next.
Sweetie Belle squeaked nervously and stiffened up as soon as she felt his hoof touch her vagina. Scootaloo chuckled at how flustered she looked, practically holding her breath with a bright red blush on her face. She chuckled even harder as Sweetie squeaked again and whispered ”I think he just licked me!”
Carrot Crunch hadn’t paid any attention to the passage of time, but all too soon the plots in front of him dispersed as the fillies they belonged to turned around almost in unison. ”That’s enough. Now it’s our turn!” Apple Bloom chirped happily.
”Oh, okay!” Carrot replied enthusiastically. He was already incredibly turned on and looking forward to letting the three fillies play with his erection, laying down on his back and spreading his legs for them.
”Ooh, he has a boner!” Scootaloo chimed, staring and pointing at his stallionhood excitedly.
”Yep!” Apple Bloom confirmed, getting down between his legs and giving it a light poke. ”My brother gets them all the time. Now then, let’s take a look at those balls of yours!”
Carrot’s eyes widened as he remembered what the fillies had originally wanted, looking on nervously as Apple Bloom reached a hoof forward to poke at his balls. He twitched as she jabbed his sensitive nuts a little harder than was comfortable, looking over them curiously as she tapped them experimentally from each side. His gut churned as she pressed her hoof right on top of his balls and rubbed back and forth with a somewhat painful amount of pressure.
”C-could you play with my cock?” he suggested in a pained voice, his breath baited as he struggled against the desire to curl up to protect his orbs from her.
”Nah, these things are much more interesting.” Apple Bloom quipped, not even looking up to him as she suddenly pressed down on his balls harder than before. His legs spasmed and he let out a high-pitched wail, gasping for breath as Apple Bloom lifted her hoof off his throbbing nuts.
”They’re much more slippery than I’d thought. And they feel like stress balls!” Apple Bloom mused.
”Oh! Let me try!” Sweetie Belle piped up, practically bumping Apple Bloom out of the way as she got in position between his legs. Carrot didn’t even have time to ask for a break before Sweetie Belle clamped her hooves around his sack, instantly squashing them painfully flat.
”AIEE! CAREFUL!” he squealed, staring wide eyed at the filly holding his balls between her hooves in a vice-like grip.
”Don’t worry, I’ll be careful.” Sweetie reassured him, despite continuing to squeeze his nuts just as tightly. He flicked his head back, groaning between clenched teeth as she relieved her pressure on his balls, just to squeeze them flat again and again. He wanted to roll over and curl up, but Sweetie had his balls in an iron grip that made any kind of escape impossible.
”Hold on Sweetie - I want to try something!” Scootaloo interrupted. The worst of his agony receded a little as she felt Sweetie Belle release his balls, but his abused nuts were still throbbing in agony.
”N-no! Please no more!” he gasped weakly, staring through hazy eyes at the orange filly stepping between his legs with a wicked grin. He tried to roll over to cover his groin, but she quickly caught his legs and forced them open.
”Don’t worry, this is something you should enjoy!” she said, lowering her head. His expression turned from fear to confusion as Scootaloo reached out her tongue, giving him a long lick across his still erect penis.
”Scootaloo! What are you doing?” Sweetie Belle gasped.
”Checking out everything he has.” Scootaloo answered with a smile. ”He did lick yours too, didn’t he?”
”Well, yeah." Sweetie said, blushing as she looked away. Carrot Crunch, on the other hoof, was looking straight at Scootaloo with equal parts arousal and relief over her not going for his balls as well. He let out a satisfied groan as she stroked his shaft, admiring its texture between her hooves. All this attention from three fillies had already gotten him on the edge, and with Scootaloo literally breathing on his cock while stroking it quickly pushed the young colt over his limit.
”Scootaloo!” he gasped as his body tensed, his cock twitching in her grip as it shot a thick squirt of cum right in the air, catching her by surprise as it splashed all over her mane and muzzle.
”Whoa! Watch it!” Scootaloo gasped, excited and surprised at what she’d managed to achieve. His cock twitched right out of her hooves, covering her with several more loads of cum before she could catch it again and turn it away from her for the last waning spurts. Apple Bloom and Sweetie Belle watched with their mouths agape as cum covered Scootaloo smiled with triumph.
”Wow, you made him cum!” Sweetie Belle stated the obvious.
”Yep. I always wanted to try that!” Scootaloo grinned.
”I wanna try it too!” Apple Bloom said cheerfully. ”Come on girls, let’s find another colt to bust!”
”Sure thing! Scootaloo said, standing up and wiping cum from her eyes. ”Oh! And speaking of busting...”
Carrot Crunch saw Scootaloo lift her foreleg, but was too late to react before she stomped it down right on his aching balls. He screamed in utter agony as all the pain dealt by the two previous fillies exploded anew, her hoof squashing his sensitive orbs like pancakes. It was just a quick jab, but the absolute gut-churning agony it caused was more than enough to leave him gagging and gasping for breath long after the three giggling fillies had trotted off to new adventures.
After a quick stop a the river to let Scootaloo wash her mane, the crusaders continued looking for more colts to bust. They joked and giggled about how freaked out Carrot Crunch had been whenever somepony touched his testicles, until Apple Bloom spotted a familiar face ahead of them.
”Tender Taps!” she greeted happily, running up to him. ”We’re so glad we found you!”
”Oh hi Apple Bloom! Hi Crusaders!” he greeted back. ”What is it?”
”We were, uh, talking about tap dancing! Could you give us a little demonstration?” Apple Bloom improvised.
Taps was surprised but more than happy to oblige. ”Sure thing!” he agreed, standing up on his rear legs. ”This one’s called hoofloose...” he explained as he started tapping his hooves with increasing speed.
Apple Bloom reared up in front of him, looking him in the eyes with a big smile on her face. For a moment he thought she was going to dance with him, but instead she swung her leg back and then kicked him full force right in the balls. He screamed in terrified pain as his nuts flattened against her hoof, the explosion of pain overwhelming his senses and cutting his dance short as he collapsed right where he stood. The fillies burst out laughing hysterically as the unfortunate colt wailed in pain with his aching balls in his hooves.
Suddenly, the trio’s fun was cut short by an angry voice coming from behind them. ”GIRLS!” Cheerilee shouted, in a voice that immediately let them know they were in trouble. They turned around slowly, coming face to face with their extremely displeased teacher. ”What do you think you’re doing?”
”Oh, hi Cheerilee.” Apple Bloom said sheepishly.
”We were, uh, playing pranks?” Sweetie Belle answered hesitantly. While it was the truth, Cheerilee’s expression made her think it might not be the answer she was hoping for.
”Do you think kicking somepony in their privates is a prank?” Cheerilee asked sternly.
”Well, it is funny.” Scootaloo answered awkwardly. ”I mean, we did try it with each other first to make sure it didn’t hurt too much.”
”What do you mean ’with each other’?” Cheerilee asked, now more confused than angry. ”You’re all fillies!”
”Yeah, but you taught that vaginas and penises come from same parts when we’re all fetuses.” Apple Bloom explained, hoping that she had indeed understood her biology lessons correctly.
Cheerilee’s expression softened. ”Oh, my little fillies... You aren’t wrong Apple Bloom, but since birth colts and fillies really don’t compare to each other like that.” she explained, sitting down and gesturing at the crusaders to gather around. ”Most of all, the testicles are more comparable to ovaries, except exposed and much, much more sensitive.”
”Oh.” Apple Bloom said, her ears drooping and expression turning embarrassed. ”We thought it was just some weird reflex thing, like how cats and dogs go stiff when you grab them by the scruff of their necks.”
”No Apple Bloom, no.” Cheerilee said, shaking her head. ”Being kicked in the testicles is really painful to colts.”
”Now I feel terrible.” Sweetie Belle said, lowering her head and looking back at their latest victim. ”Is there anything we can do to help him?”
”You can start by apologizing and getting him an ice pack.” Cheerilee said empathically, standing up to get on her way. ”And for tomorrow, I want you three to write an essay about what you learned today.”
”Okay Cheerilee!” the fillies agreed, waving her goodbye and turning their attention to comforting the still curled-up colt.
”...and that’s how we learned that it was not okay to kick colts down there.” Scootaloo finished the trio’s presentation in front of the class.
”We’re really sorry about what we did.” Apple Bloom apologized.
”Can you forgive us?” Sweetie Belle finished, looking over the classroom. Rumble looked mostly embarrassed, while Carrot Crunch with his massively swollen package tried not to even look at the ball-busting crusaders. After a second of awkward silence, the colts begrudgingly mumbled their forgiveness and the fillies let out a collective sigh of relief.
After the apology, the rest of the school day went as usual. However, once the school was over and the crusaders met up for one more chat before heading to their respective homes, they were approached by an unexpected colt.
”Um, Scootaloo?” Crackle Pop said, tapping her on the shoulder.
”Oh! Hi Pop.” she said, preparing for another apology. Instead, his next words took her completely by surprise.
”I was wondering if you could... uh... kick my balls too?” the colt said, brushing the back of his neck with an embarrassed blush on his face.
”What?” the crusaders gasped in unison.
”But doesn’t that hurt?” Scootaloo asked, thoroughly confused. ”Like when you hit your nuts while scootering yesterday?”
”Yeah, it hurts.” he said, searching for words to convey his intentions. ”It’s just that... well... I kinda liked it when you laughed about it.” he continued, his face blushing ever redder as he did.
”You liked it when I laughed at your balls?” Scootaloo asked, tilting her head quizzically at what this colt was babbling about.
”Yeah!” he nodded excitedly. ”And it would be even better if you were the one who hurt them! So... could you do it?” he asked.
Scootaloo glanced over to Sweetie Belle and Apple Bloom, who answered only with a confused shrug. She turned back at the colt looking at her with pleading eyes and shrugged her shoulders. ”If that’s what you really want, then okay!”
Crackle Pop let out a happy whinny as he jumped in place, excitedly turning around to expose his dangling ballsack to her. Scootaloo could catch a glimpse of his cock drooping from its sheath as he did, but her attention was completely stolen by the pair of vulnerable nuts practically shoved to her face.
”Are you really sure about this?” she asked, lifting his jewels ever so carefully with her hoof.
”Yep! Don’t worry, give them your best shot!” he answered, getting ever more excited as he sensed Scootaloo turning around behind him. He could feel her rear hoof touch his sack as she measured her optimal bucking distance in preparation.
”Okay, here it comes! Three... Two... One...” Scootaloo counted down, drawing her leg back and launching it at his groin as hard as she could. Her hoof struck its targets hard, squashing his nuts like putty as the entire weight of his hindquarters lifted off the ground atop them. He flopped down screaming like a banshee, cupping his balls in unimaginable agony. His throbbing cock however was ejaculating like a fountain, launching massive squirts of cum in every direction as the wailing colt rolled on the ground holding his testicles.
The crusaders watched with mouths agape as the writhing stallion painted the ground white with semen before his intense orgasm ran its course, leaving him shivering in a sticky puddle with his spent member slowly softening between his forelegs.
”Wow.” Sweetie Belle remarked. ”I think you broke him.”
Apple Bloom cautiously lifted one of his rear legs to take a look at his balls. ”Nope, they still look intact.” she said, unceremoniously dropping his leg and eliciting a sharp yelp from Crackle as it landed on his tender nuts.
”Guess he really did like it.” Scootaloo remarked, idly kicking her rear leg to clean it of some stray splashes of cum.
All of a sudden, the ponies felt a crackle of magic in the air as Crackle Pop started to shine with a golden light. The crusaders watched in amazement as a gentle magical wind lifted him off the ground, and with a bright burst of light a cutiemark of a bursting bubble appeared on his flank. The light and wind faded away, gently lowering him onto his feet before he slumped back down to continue nuring his agonizingly throbbing groin.
Scootaloo blinked. ”Wow.”
”Yeah. Wow.” Apple Bloom nodded, still in disbelief of what she’d just witnessed.
”I’d have never thought somepony could get a cutiemark for getting kicked in the balls.” Sweetie Belle mused, her expression brightening as she realized what she’d just said. ”We helped another pony get his cutiemark!” she squealed, jumping with joy. The rest of the crusaders quickly joined her in celebrating another job well done, finishing with a triumphant three-way high-hoof.
”Cutiemark Crusader Ballbusters! YAY!”
Author's Note
This story was requested by Buttsaucer, and while I couldn't finish it in time for Christmas I'm glad he found it worth the wait. It also ended up being by far the longest story I have ever written to date.
I hope you enjoyed it too!
