Cattail made his way through the Everfree forest, ears open for dangers and eyes looking for exotic herbs to bring home. He wasn’t in Ponyville just to collect ingredients though, at least not for himself. Fluttershy had told him about a zebra living in this woods, and that she was looking for a stallion to help her collect some magical ingredients she couldn’t get herself. He knew he didn’t look like the kind of strong adventurer she was expecting, with his skills in herbalism and living in the wilderness he was certain he could help her get whatever she needed.
Following the path, he soon arrived at the tree cottage much like his own. He smiled at the familiarity and proceeded to knock on the door. The door opened and the exotic resident of the hut greeted him with a warm smile.
”Hello there, pony dear! What brings you to travel here?”
”Greetings, Zecora! My name’s Cattail. Pleased to meet you!” he introduced himself. ”Fluttershy told me you needed help with some kinda seeds.”
”Yes indeed, true as rain, I am looking for some seed of pain.” she replied. ”Please follow me, step inside, for you are in for quite a ride!” she finished, stepping out of the doorway to let him in.
Cattail stepped inside the hut, taking a look around. While foreign in design, it was cozy and filled with all kinds of herbs and brewing supplies. However, Zecora didn’t seem to be preparing for any kind of field trip, but instead making a comfy bed of pillows in the middle of the room. He briefly thought she just wanted to sit down for a chat, until he realized she had made bedding for just a single pony. She gestured him to have a seat, which he did with some mild confusion about the zebra customs.
”Zecora? What can you tell me about this ’seed of pain’? I’ve never heard of such a plant.”
”Oh, seed of pain comes not from plants.” Zecora explained as she sat down in front of him. ”But from what you have inside your pants.”
”Wait what?” Cattail asked, wide eyed from surprise. ”I mean - no offense but - I mean...” he stammered. The surprise was far from undesirable, but being approached so directly was unexpected nonetheless.
”Did Fluttershy not tell you this?” Zecora asked. ”Seed of pain is stallion jizz.”
”Really? I see.” he answered, blushing at her straightforwardness. ”Well, I’d be glad to help you with something like that!” he said with excitement.
”Extracted from some aching balls.” Zecora specified. ”Which is why so few have answered my calls.”
”Say what?” Cattail asked again, his excitement dropping in an instant.
”Worry not, I won’t be too rough. I’ll slap them around just barely enough.” she said, gently rubbing his thigh with her forehoof.
Cattail cringed, weighing his options in his mind. He wasn’t too fond of being hit in the nuts, but he had already traveled all the way here, so it would be a shame to leave without actually lending a hoof first. The beautiful zebra looking him in the eyes as she stroked his thigh may have helped to cloud his judgement, but with a deep sigh he reluctantly agreed. ”Fine. I’ll do it. Just a little though, alright?”
”Thank you Cattail, you’re the best! Just lie down and let me do the rest!” Zecora said, relieved to hear his answer. Cattail laid down, his back supported by the pile of pillows to give him a view of the zebra as she hefted his testicles in her hooves. ”My, what treasures in this sack." She said, impressed by their size and weight. ”Are you ready for a smack?”
Cattail drew a few breaths to steel himself. ”As ready as I’ll ever be.” he said, biting his teeth and holding his breath as zecora rest his balls on one hoof, the other rising ominously above it like a hammer to an anvil. Looking him in the eyes one more time, she brought her hoof down with an audible slap, his balls flattening with a sharp jolt of pain as her hoof bounced off of them.
”AAAARGH!” Cattail screamed, his legs kicking the air as he rolled on to his side, holding onto his balls as the gut-churning pain spread through his stomach. ”Ow my balls! Oww! Oooh!”
Zecora snickered, unable to hide her amusement as she watched the plump stallion rocking on the floor, moaning and cradling his balls. ”Sorry Cattail, that was fun! Just few more and you’ll get to cum!”
Cattail, already breathless from the searing pain couldn’t believe what he just heard. ”M-more?”
Zecora smiled sheepishly. ”I am sorry, my stallion friend. It is not yet time for a happy end. To make seed of pain, your balls need to be hit again, or else the first hit will have been in vain.”
Cattail grumbled to himself. He was way too quick to help mares in need - something he thought he’d gotten over after Twilight’s idea of using his balls to distract flash bees. His regrets were cut short as Zecora lifted his rear leg and exposed his aching balls to herself.
”There’s no time to waste, we need to make haste!” she said, eyes locked on his groin. He could barely draw breath to protest before she punched him right in the balls, her hoof squashing his already tender sack against his pelvis.
”AIEE!” he screamed in a panicked, uncharacteristically high-pitched voice. His legs kicked in the air as Zecora held him steady with one hoof, the other continuing to grind his flattened eggs beneath it.
”Just a little longer!” Zecora said as she struggled to keep his slippery nuts squashed. ”Your discomfort will make the seed stronger!” she explained, lifting her hoof briefly to stomp down harder.
Screaming and kicking for his dear life, Cattail finally managed to get the mare off his nuts and roll over to his side, face and body frozen in a tense expression of unfathomable pain. His belly made it hard to see his balls, but they felt like they’d been put through a mangler and reinflated with pure agony.
”That should be enough for the beating.” Zecora said, walking around him to admire his bruised package. She didn’t know what ball-pain felt like, but they looked painful enough for some high-quality potions. "Now it’s turn for gentler treating. How about a blowjob, to balance out the painful throb?”
Cattail could barely hear her words over the haze of agony in his mind, but didn’t resist as Zecora gently rolled him back onto his back, even as he winced at the sensation of his incredibly sore testicles rolling over his leg and coming to rest between his rear legs again. His teary eyes opened in surprise as Zecora spun around, lifting her rear leg over him and laying down on top of him, her pussy scooting down to his face as she pushed back far enough that he could feel her breath on his balls.
”Cattail dear, you’re in luck.” she said as she gently lifted his balls on her hooves. ”Now that your balls have been struck, it’s time to give your dick a suck.”
As nice as the offer was, Cattail’s balls were in too much pain to appreciate it. ”Not yet please. Just give me a minute...” he groaned, but Zecora had already started licking his balls gently. He was subconsciously terrified of letting her do anything more to them, but her warm, soothing tongue was in fact helping the unbearable agony at least a little. Realizing the situation wasn’t going to get better than this, he wrapped his forelegs around her body to try and focus on the sexy instead of painful sides of it. He buried his nose between her flanks and took a good whiff of her marehood as he caressed her with his hooves.
Zecora let out a pleased moan, rubbing his sheath softly as she wiggled her hips around his head. ”Oh my stars, you handsome stud! Do you like my striped butt?”
Cattail smiled. He didn’t get called handsome often, and coming from a sexy mare like this it felt good indeed. He gave her pussy an experimental lick as his cock started to stir from its sheath. Zecora twirled her tongue against the tip of his expanding dong, moaning with pleasure as she ground her hips against his face.
”Oh yes, make it rise!” Zecora gasped, nuzzling his member passionately. ”I want to see your fullest size!”
Cattail licked her lips more assertively, making her wink passionately. Zecora glomped down on the tip of his dick and started to bop her head up and down. Her hoof wandered down to his balls and groped them lightly, making Cattail stiffen at sudden flash of pain. Zecora noticed the effect this had on him, and quickly got her other hoof down to grope his sore nuts as well.
”HooOOOH! TOO TIGHT!” Cattail gasped, withdrawing his head from her haunches as the pain of his crushed balls overwhelmed his mind again. Zecora didn’t stop though, instead only increasing the speed and intensity of her sucking as she squeezed his sore balls harder. He screamed in wide-eyed terror, frozen in place between the sensations of having his dick sucked and his balls squashed for what felt like an eternity. He was almost passing out when his cock erupted inside her mouth, blowing her cheeks full in an instant. Zecora’s eyes shot wide open in surprise, but without missing a beat she grabbed a bowl and opened her mouth to let his cum splosh down to it, even as more and more powerful gushes of it shot up against the inside of her mouth. She drew a quick breath through her nose and brought her hoof back to his balls, punching them again and again, his screams of pain rising ever more frantic even as his spasming cock kept unloading absolutely prodigious loads of cum into the zebra’s face.
Finally, his orgasm ran out to the point that even Zecora’s last hard blows failed to squeeze anything more out of him. Cattail’s mind was reduced to a haze of incomprehensible pain, his testicles throbbing like every beat of his heart was a punch of its own, right into their agonizingly swollen mass. Zecora grabbed the bowl with her teeth and pushed herself off of him, causing him to wail in pain as her last hoof dragged right over his left testicle. He reached down to gingerly feel his balls, equally incredulous of just how massively they had swollen and that they were intact in the first place.
”Sorry about the last surprise.” Zecora said as she carefully poured the contents of the bowl into a large, conical flask. ”I had to maximize my prize, for few are those who help me twice.”
Cattail couldn’t hear her over the throbbing agony between his legs, having curled up into a fetal position in the now messed pile of pillows. Zecora chuckled as she watched the orange stallion cradling his eggs, entirely occupied by nursing his poor, tender stallionhood.
”Thank you Cattail for fulfilling my request. You have truly earned your rest.”
