Stick and Carrot, Hoof and Nuts

Throwing the door open with a careless bang, Zephyr Breeze walked into his parents house."Welp, I tried!" he said nonchalantly, tossing his duffel bag onto the nearest chair he came across. ”Just because I arrived a tiny bit late they didn’t even let me get into the whole audition!” he continued talking before noticing that neither of his parents were at home. Instead, he saw his sister Fluttersy sitting in the living room, looking at him with an annoyed glare.
”Zephyr Breeze.” she said sternly.

”Oh hey sis! How’s Ponyville treating you?” he deflected the incoming blame. ”I’m applying to the royal guard. They didn’t let me in yet because of some scheduling mishap, but they will eventually. Everypony gets their five chances.”

”That’s three chances.” Fluttershy corrected. ”And your last chance is just two days from now.”

Fluttershy sighed and facehooved. Back when she had helped his brother get his degree everything had looked so promising. He’d finally finished his education and was well on his way to becoming a professional mane therapist or stylist. Fast forward a few months, and she instead gets a letter from her parents about how her brother had now decided he was too manly for manestyling and wanted to become a royal guard instead. He had already failed the first audition and wasn’t doing anything to prepare for the second one either, so they had begged Fluttershy’s help get her lazy brother back on the right track again.

By the time Fluttershy took her hoof off her face, Zephyr had already gotten comfortable on his parents couch, reclining and reading a comic book. Fluttershy stood up and trotted next to him.

”Zephyr, if becoming a royal guardspony really is what you want, you will have to work harder.” she said, pressing his comic book down with her hoof to look him in the eyes. ”You must study for the upcoming audition.”

”I will, I will. I’ll get right to it first thing tomorrow morning.” he shrugged, pulling his comic book from under Fluttershy’s hoof and straightening it back in front of his face. All of a sudden, her yellow hoof came slamming down right onto his unprepared balls.

”AUGH!” Zephyr yelped, flinging the comic book aside as he jerked alert, quickly covering his hurt testicles with his forehooves. ”What was that for?” he asked in disbelief over what she just did.

Fluttershy stood sternly by his side, looking deep into his eyes with an assertive gaze as she answered, her voice soft yet firm. ”It was a gentle prod to get you moving.” she said, using her hoof to pet his thigh reassuringly. ”You’re having trouble with your self-discipline again, so I’m here to help you focus. You do want to join the royal guard, right?”

Zephyr listened silently as he rubbed his nuts. He wanted to tell Fluttershy she was being unreasonable, but he knew she was right about the whole thing. He rolled his eyes with a resigned sigh as he reluctantly gave in. ”Allright, I guess I could get started already...”

”Atta boy!” Fluttershy said with a smile as his brother got off the sofa and fetched a textbook from his duffel bag. ”I can quiz you on the first chapter when you’re done.” she suggested, her brother giving him an approving mumble through the book in his mouth as he walked back to the sofa with a funny gait.

Zephyr Breeze spent the next few hours reading, his legs comfortably spread over the backrest and hoofrest. Fluttershy had picked an old book from their parents bookshelf and was silently reading it in an armchair for company and mental support. The textbook for royal guard recruits wasn’t difficult - in fact it, was boring. Keep your armor clean, stand still, refer to princesses as you highness... he didn’t need a book to know this kind of stuff! Instead he started skipping forward, leaping over common sense parts so he could get straight to learning new things. Before he even noticed, he had finished the entire book in one sitting.

”Done and done!” he proclaimed confidently as he slammed the book shut.

”That’s great!” Fluttershy congratulated as she gently put her own book down. ”Did you read the entire chapter already?”

”Chapter? Ha! I just finished the entire book!” Zephyr said, beaming with pride as he tossed the textbook next to his sister.

”The whole book? Wow, that’s amazing!” Fluttershy said happily, jumping off her chair to fetch the book. ”Would you like me to quiz you all chapters at once?”

”Fire away sister.” he said, sitting down on the floor next to her.

Fluttershy opened the book, scanning it quickly for questions to ask. ”Okay, here’s one: You are guarding a door on the side of a long hallway. One of the princesses walks past you, from one end of the hallway to the other. What do you do?”

”Salute her.” Zephyr answered, doing a relaxed mock salute for emphasis.

Fluttershy leaned forward. Zephyr didn’t have time to realize what she was doing before she reached forward and tapped his balls firmly with her hoof. Zephyr yelped in pain and threw his forehooves down to cradle his nuts as Fluttershy kept talking like a teacher. ”Wrong. You only salute a princess if she’s approaching the door you’re guarding, otherwise you stay still and don’t move. Let’s try another question...”

”H-hold on!” Zephyr interrupted her, gesticulating wildly with one forehoof while keeping the other one between his legs. ”Are you going to hit me in the balls every time I get a question wrong?”

Fluttershy smiled. ”Don’t worry brother. You did just memorize everything, didn’t you?” she said sweetly as she gently touched his hoof.

”Of course I did! I read and memorized everything I didn’t already know, so...” he stopped, not knowing how to form his statement in a way that wouldn’t sound like he’d lied. Fluttershy gestured him to spread his legs, which he reluctantly did, wondering how in Equestria his little sister played him into going along with this.

Fluttershy lifted the book back to her face and sought out another piece of trivia. ”Next question: What do you do if your armor gets damaged during your shift?”

Zephyr thought hard about the answer, not because the question was hard but because he now had a lot more at stake than he’d planned for. Remembering a snippet from the equipment chapter he finally answered with some confidence. ”I seek out the quartermaster for replacement and return to my post.”

Fluttershy leaned forward again, her forehoof extended and eyes on his nutsack. Zephyr braced himself for impact as her hoof tapped his balls again, lightly but firmly jolting them against the hard wooden floor. She wasn’t hitting hard by any means, but the cumulating pain from her previous hoofstrikes was making it worse.

”Aa-aah!” Zephyr whimpered, kicking his legs and staring down at his aching balls. Fluttershy smiled at him before continuing the quiz as usual.

”Wrong. A royal guard must always finish his shift, regardless of his gear. But after the shift they do indeed get a replacement armor from the quartermaster.” she said to compliment him for the part he got right before moving to the next question.

”You are guarding an invitational event when a pony approaches you telling she has lost her invitation but wants to be let in anyway. What do you do?”

”I... arrest her?” Zephyr guessed. This was exactly the kind of common sense drivel he had been skipping over, yet now that his balls were on the line it all suddenly seemed much more important.

”Wrong.” Fluttershy said, shaking her head. Zephyr watched with terror as his sister leaned forward with her forehoof raised, bringing it down on his tender balls yet again. He could feel his bruised balls flex like rubber as her hoof bounced off them, eliciting another scream of pain from him. Instead of returning to her textbook, Fluttershy slammed her hoof right back down and held it there, Zephyrs screams rising to frantic new levels as he realized the hoof pressing on his testicles wasn’t about to let go.

Fluttershy stood up to easier hold her hoof atop his squirming balls, her brother screaming like a filly as he ineffectually pawed at her hoof in an attempt to relieve its agonizing pressure. ”You didn’t really read the whole book, did you?” she asked, her voice soft but disappointed. ”There aren’t any shortcuts to success, like you should have learned that by now. If you want to achieve your goals you really need to work for them.” she lectured softly. Zephyr could only look up at her and beg with his eyes, unable to form words over the feelings of of pain and nausea rising from his testicles as her hoof kept pressing down against them.

Fluttershy finally released her hoof from his groin, his hooves immediately shooting down to cradle his painfully throbbing testicles. She hugged him gently, petting the back of his head with her hoof as she comforted him. ”There there... I’m sure you’ll do much better tomorrow. You just need a little help staying focused, that’s all.”

Zephyr leaned into Fluttershy’s hug, tears in his eyes and both hooves still nursing his balls. ”I... thought I... already knew the simple stuff.” he spoke between gasping for air.

Fluttershy pulled back to look him in the eyes, still holding onto his shoulders with her forelegs. ”I know you did. We’ll just try again tomorrow, you can study more and take care of your little balls until then.” she said, kissing him on the forehead before letting go of him.

Zephyr slumped on the floor as Fluttershy left for some errands, his lower body still stunned by the throbbing pain between his legs. After a few minutes it went down enough that he could finally get up to fetch an ice pack and go to his room to suffer in peace. For a while he was content just to rest the ice pack on his swollen groin, but soon simply laying on the bed got boring. He hobbled back to the livingroom to fetch his comic book, only to notice the royal guard textbook where his sister had previously busted his balls. ”Oh well, might as well do something useful...” he mumbled as he picked up the book, deciding to use his time with studying to spare his testicles from taking another beating.

The next day, Zephyr woke up to the scent of pancakes wafting from the kitchen. After sharing a breakfast Fluttershy had suggested him to get right back to studying while she cleaned the table and did the dishes. Once she was ready she joined him in the livingroom to check how his studies were going.

”Page 72 out of 214. This book is a slog to get through.” he grumbled. Being less than halfway through the material after the whole first day didn’t sound like an achievement, but at least he had really read every single word of it.

”Good job Zephyr! Woohoo!” Fluttershy cheered him. ”I think now is a good time to test what you have learned.” she added.

”N-no thanks, I’m already pretty confident with my knowledge!" he gulped, not at all excited about the prospect of having Fluttershy hit him in the balls again. On the other hoof, the further he’d read the more there would be to remember and the harder the quiz would be.

”Come on, don’t be shy. I believe in you.” Fluttershy said as she sat down in the same spot she did yesterday. Zephyr groaned in protest as his sister gestured him to join her, eventually giving in and sitting down next to her.

”Okay, let’s continue where we left off.” Fluttershy started. Zephyr cringed at the memory as well as the implications of it. ”You are guarding an invitational event when a pony approaches you telling she has lost her invitation but wants to be let in anyway. What do you do?”

To his delight, he was prepared for this. ”I deny entrance and send her away, unless of course she seems dangerous or tries to get in by force.”

”Correct!” Fluttershy chriped happily. However, to his horror she started reaching down to his groin despite his right answer. He was preparing for pain, but instead she planted a gentle kiss on one of his balls. She then got back up and continued on to the next question, leaving her brother speechless.

Zephyr got the second question correct as well, earning him another sweet kiss on his other ball. The way this quiz was going was an unexpected but welcome surprise, causing a reaction in his stimulated lower region.

Fluttershy giggled as she noticed him trying to cover his growing erection. ”It’s okay Zephyr. If you do well I can kiss it too.” Upon hearing this, his cock shot to full mast almost immediately.

Zephyr correctly answered the third question and Fluttershy delivered on her promise. She gently took his cock into her hooves and sucked gently on the side of its tip. Zephyr gasped with pleasure at her sensuous act, actually looking forward to the rest of the questions.

Unfortunately for him, by the fourth question he made his first mistake.

”Sorry brother, but you know the rules.” Fluttershy said, tapping his balls with her hoof. Zephyr yelped as the familiar wave of pain shocked his nethers again, fighting to suppress it for the prizes awaiting him.

His sister gave him a second to compose himself before continuing to the fifth question. Zephyr made another mistake, earning him another hoof to the balls. Clenching his teeth as he waited for the immediate peak of the pain to subdue, he suddenly noticed Fluttershy closing the book and preparing to get up.

”W-wait, what are you doing?” Zephyr asked as his sister stood up.

”Oh, those were the only questions I had. You did well though, just keep reading and I’m sure you’ll make it!” she repied.

”But... you can’t just stop! Not like this!” he exclaimed, gesturing at his fully erect cock.

”Patience, Zephyr, patience.” Fluttershy hushed him. ”Tomorrow is the auditioning day. If you pass I will reward you much better than this.”

”But...” her brother whined, his cock twitching impatiently in the air.

”Today you can take care of it yourself if you need to.” Fluttershy said with a barely stiffled giggle.

Zephyr let out a frustrated groan as he rolled his eyes and trotted to the bathroom. She had busted his balls again, but at least he didn’t intend to keep reading with blue balls as well.

It was the last day of guard auditions. Thanks to Fluttershy, Zephyr Breeze had gotten to the classroom both in time and well-prepared, and had finished his test mostly without difficulty. He was now nervously waiting to receive his grade, as the guardsmare conducting the test called the applicants by name to pick up their test results. Everypony else got their test results before him, their reactions ranging from joyous whinnies to visible sadness. When Zephyr’s name was finally called, he strode to the guardsmares desk brimming with confidence.

His jaw dropped when he saw his results. 73 points out of a hundred, yet failed.

”Excuse me miss, there seems to be something wrong with my results. You see, from what I’ve heard you only needed to score above seventy percent to qualify.” he pointed out.

The grey mare at the desk took his paper to check it, handing it right back to him. ”Nope. You got 94 points of the theory exam and zero points from the physical exam. That’s a total of 47 percent.”

Zephyr’s heart sank like a stone. He had completely forgotten about the physical exam, and neither Fluttershy or his parents could have reminded him because he’d told them he had already taken care of it. He started to sweat as he thought of Fluttershy’s reaction to this after all she’d put him through, starting to hyperventilate as panic started to rise in his throat.

”I-it’s not too late to take the physical test now, right? Or substitute it for something else?” he begged. ”Please! If I don’t make it through my sister is going to crush my balls!”

The mare raised her eyebrows in surprise. She’d heard a lot of excuses and a lot of begging, but this was something new. ”She what now?”

”She’ll crush my balls!” Zephyr repeated, grasping the one lifeline that seemed to elict a reaction from her. ”She’s been busting my balls all week and if I come home with failed papers she’s going to buck my balls to mush!”

The guardmare rubbed her chin in thought, her face slowly turning into a devious smirk. ”Maybe there is a way you could get approved after all... but it’s going to cost you.”

”I’ll do anything!” Zephyr pleaded. The guardsmares tail flicked as she smiled at his desperate pleading.

”I could let you pass with a personal affirmation... but in return you will have to let me buck you in the balls!” she declared with an excited grin.

”What? No! That’s what I’m trying to-” Zephyr protested, but was cut off as the mare explained herself.

”It sounds to me like you are going to get bucked in the balls either way. I’m just offering you a chance to also get accepted into the guard for it.” she explained, leaning back and licking her lips with anticipation. She could see Zephyr’s eyes dart from side to side as he feverishly weighed his options. ”Actually, make that three bucks. I am taking a risk by vouching for you through after all.”

Zephyr’s jaw dropped as the price for his admission suddenly got hiked up. He didn’t like it one bit, yet really had no choice but to accept it. ”Alright... But you’ll have to be super gentle, okay?” he demanded.

The guardmare replied only with an amused chuckle, making Zephyr Breeze swallow nervously. She slowly walked around her desk before gracefully stretching each of her rear legs one by one. ”Belly on the desk. Tail up, legs spread.” she commanded, gesturing him to get in position.

Shaking with fear, Zephyr lifted his forehooves onto her desk and lowered his body against its surface. Spreading his legs, he could feel just how defenseless his dangling balls were as the scary mare circled them like a shark. He fliched as he felt a touch in his sensitive bits, but the guardmare had just lifted them with her forehoof to feel their weight. Zephyr was getting more nervous by the minute as the mare hummed with satisfaction before letting his balls flop down to dangle freely.

”Are you ready, recruit?” she asked, turning around and flexing her leg to gauge the distance between herself and his genitals.

”Just a minute.” he responded, taking a few deep breaths before continuing. ”First we need to-”

His words were cut short as the guardmares rear hoof slammed against his testicles with unfathomable force. He couldn’t even notice when he’d started screaming, the explosion of pain from his testicles flattening between her hoof and the desk far worse than he could have imagined. He could barely hear mare’s satisfied laughter, his mind completely filled by his crushed balls.

”AAAA!” Zephyr screamed, gasping for air as he tried to process the sheer might of the blow his balls had just taken.

”Good boy! Here comes the second one!” she declared. Zephyr barely had time to refill his lungs before another powerful hoof struck his balls, slamming them against the desk with enough force to move it forward by few inches. She was relishing every moment of this, focusing on feeling his squishy stallion parts flex against the bottom of her hoof.

”And here’s the big three!” she finished, bucking his balls hard one more time. The pitch of his screams climbed even higher as his rapidly swelling testicles were smashed flat yet again, absorbing the full force of her buck as they deformed along the contours of her hoof. She watched as her plaything’s legs and tail spasmed upon her hoof striking his defenseless balls, savoring the reaction her bucks elicted from him. She let out a deep, satisfied moan as she slowly set her leg down again, her whimpering victim sliding down the desk like a wet rag and curling up around his battered stallionhood.

”Thanks for the fun big guy. You really took it like a man!” she congratulated as she turned to face him, smiling smugly at the stallion she’d just brought to tears. ”Now just wait here, I’ll get your papers ready in no time.” she said, leaving the room with her tail held high and a happy skip in her step.

Zephyr felt close to vomiting, every vein in his testicles throbbing like they were about to burst. If he had known what kind of number she was going to do on his nuts he’d never have let her near then, but here he was, struggling to breathe with gut-wrenching agony radiating from his bruised balls.

An indeterminate lenght of time later the guardsmare returned with an envelope in her mouth and a satisfied glow on her cheeks. She set the envelope down next to the shivering male before adressing him. ”Congratulations Zephyr Breeze, looks like you just passed your physical test with flying colors!”

Zephyr could only respond with a quiet whimper, hurting too much to even think about words to say.

”I’ll just let you rest here. Remember to lock the doors when you leave, okay?” she said with a chuckle, not even expecting him to answer before she left Zephyr alone to nurse his balls.

It had to have been over an hour before Zephyr could stand again, flinching with every tiny step as he slowly made his way out of the classroom. He was lucky he could fly, as walking the entire way home with his tender ballsack would have been completely out of the question. No physical activity felt good right now, but he did made it safely back home with his letter of acceptance clenched between his teeth.

As he opened the door, he forced himself to smile and put on his cool act. His way of passing the exam wasn’t exactly a honest one so he had to keep it a secret.

”Helloo Flutters, I’m home!” he called, startling his sister who had been pacing around the livingroom.

”There you are!” Fluttershy said with a breath of relief. ”I was so worried when you didn’t show up after the audition. Where were you?”

”Just celebrating with my fellow guardsponies. You know how I roll!” Zephyr answered, leaning against wall to appear more relaxed.

Fluttershy gasped with delight. ”So you made it? That’s wonderful!”

”See for yourself!” Zephyr said as he tossed the envelope to her. Fluttershy carefully opened the envelope and read aloud the document within.

”...with personal recommendation from sergeant Star Kicker for having true balls of steel.” Fluttershy finished. ”Oh Zephyr, you made it!” she exclaimed, throwing her hooves around his brothers neck in an excited hug.

”Of course I did!” Zephyr said through clenched teeth. Star Kicker? He really should have asked her name before agreeing to anything. He sat down to return the hug, nearly yelping aloud as his sensitive testicles hit the ground.

Fluttershy released the hug and looked Zephyr in the eyes, blushing lightly as she spoke. ”Now that you made it, you truly deserve your reward.” she said, gently placing her hoof against his swollen balls.

Zephyrs smile wavered briefly as he realized he had a problem. His balls were redder and way more swollen than even after the harshest punishment Fluttershy had ever dealt them. If she noticed them she could start asking questions he didn’t want to answer. Right now though, she was lovingly gazing into his eyes and hadn’t yet noticed the full size of the testicles she was petting.

As Fluttershy started to lower her gaze, Zephyr did the first thing he could think of and pulled her into a tight, romantic kiss. Fluttershy was taken by surprise, her hoof sinking hard against his sensitive balls as she tried to stabilize herself. Her scared little squeak was quickly silenced by her brothers kiss, while kissing his sister was the only thing keeping Zephyr from screaming out loud as his already tender balls were squashed yet again. He broke the kiss after only a second, looking Fluttershy in the eyes while taking her hooves on his to keep them safely away from his swollen nuts.

”Don’t worry Flutters, you don’t have to do anything for me.” he said with a forced smile, the throbbing pain in his balls renewed by her stomp. ”After all you’ve done, I should be the one rewarding you!”

Fluttershy blushed, holding her hooves on his as she smiled with pure happiness. ”Oh thank you Zephyr! That’s so thoughtful of you!”

He got scared for a moment when Fluttershy lowered her hooves to the floor again, but to his relief she turned around to present her plot to him. ”Maybe... we both deserve a reward.” she said coyly, flicking her tail to the side and waving her hips seductively.

”You read my mind, sis!” Zephyr agreed, standing up to hide his balls behind him as he stepped up to her rear. He wasn’t too keen about putting his sore nuts through this, but it was also his best way to keep his cover. He lowered his head down to give Fluttershy some teasing licks across her pussy, elicting pleasant moans from her while he coaxed his own member to grow despite the two aching testicles right behind it.

His sister moaning gently and his erection at full strenght, he reared up and pressed his cock against her. Fluttershy let out a cute little squeak as he pushed forward, slipping inside her and slowly pressing deeper. He soon hilted inside her, the warm tightness of her body washing away any doubts he’d previously had about this. He started to slowly slide his lenght in and out of her, nuzzling the back of her neck as she shivered with pleasure.

”F-faster...” Fluttershy asked softly, her wings flared wide and her dripping pussy winking around his shaft. Zephyr picked up his pace, elicting more pleased moans from him and his sister. She quickly caught onto his rhythm, thrusting her plot backwards to meet his thrusts. His balls hurt as they slapped against her with each thrust, but the pleasure of her sex kept him going.

”Faster!” Fluttershy squeaked again, panting heavily as her brothers cock slid back and forth inside her. Zephyr steeled himself and started pistoning in and out of her, pushing through the pain as his balls slammed back and forth on his race to finish this. Fluttershy let a long soft squeal as she reached her orgasm, her pussy clenching around her furiously thrusting brother. With a few more thrusts Zephyr peaked as well, layers of relief washing over him as he hilted inside her one more time.

”Flutters!” he cried as his cock twitched, shooting its load inside her squirt by squirt. Spent and aching but satisifed, he pulled out of her and moved on to nuzzle her face.

”Oh Zephyr, that was fantastic!” Fluttershy said with rosy cheeks, giving her brother a gentle kiss on the lips.

”Y-you too.” Zephyr replied, knees weak from everything his genitals had been through. He knew his sister would appreciate chatting after sex, but all he wanted at the moment was to take his swollen orbs to a soft bed as soon as he could. Luckily for him, Fluttershy had one more surprise in store.

”You know, there’s one more present I bought for you yesterday.” she said, trotting off to get something from her saddlebags. She came back with a brand new comic book and held it up to him. ”We could read it together if you’d like.”

”Wow, thanks sis!” Zephyr exclaimed. ”Is it okay if we read it in my bed? It’s been an exhausting couple of days.”

”I would love to!” Fluttershy replied with a warm smile.

Soon the two ponies were in his bed together, laying side to side under the blanket with the comic book spread open in front of them. Zephyr Breeze had a new job, a loving family, and in a few days he should be able to walk normally again. Thanks to his sisters help, his future was looking bright once more.

The End

Author's Note

This is my last entry for the Sibling Incest is Wincest contest, as I simultaneously ran out of time and brother-sister pairs to write about. The contest may be over, but I've had so much fun with writing these past weeks that I can confidently promise to keep writing in the future as well. The comments and feedback I've gotten have been extremely rewarding as well, even from the people who don't normally enjoy the ballbusting fetish. :twilightsmile:

Thank you for reading, I hope you enjoyed it!
