Treacherous Training

Story by Zumiumi on SoFurry

, , , ,

Hey, I'm back. This time I wanted to try a little something outside of a proper League match, so I figured what would be better than training for a League match? It's a little longer than my previous two stories, and I sometimes found it a little hard to keep things flowing well, so any and all constructive feedback is appreciated.

An unlucky Vulpix guy gets his nuts bashed around by his curvy Nidorina buddy. Hijinks and popped balls ensue.

This story contains ballbusting and castration, as always read at your own risk!


This is a terrible idea. Like, so stupid. Why am I doing this again?

There were a lot of thoughts running through Vee's head when he looked up at the big double doors to the Golurk's Gym, its wall of windows reflecting the street lights from outside. The vulpix, dressed in some simple workout pants and a t-shirt, his bundle of fluffy tails drooping low in apprehension behind him, shook his head and sighed. The place was empty, having closed a few hours prior, but his friend Dina worked there and would have the key with her.

Dina was also the reason he stood there in the dark in front of an empty training center. The nidorina had recently expressed an interest in the Underground League, much to Vee's concern, and that interest had grown into a full blown desire to get her feet wet so to speak. She had already signed up for a match later in the week, some amateur night where she'd be put to the test against some poor schmuck, where the two of them could rough eachother up and maybe see if they had what it took to move on to proper fights. But as the day approached and Dina's excitement grew, so too did her trepidation. Apparently the Nidorina harbored some doubts about her fighting skills, specifically the sort of fighting skulls actively encouraged by the League. Though she was a rough n' tumble gal, she hadn't ever really gone after a pair of nuts before, and certainly not with the intention of breakin' em. And so, she came to her best bud with a proposition- let her beat his balls around a little. That was it. Just a lil bit of practice. Nothing serious. Vee nearly choked on his lunch when she suggested it, and was about to respond with a sensible "fuck no!" when Dina suggested they should fight in the nude, to be true to the rules of League.

Of course, boys will be boys, and the promise of staring at his stacked galpal in the nude for the course of however many hours of practice made Vee much, much more willing to accept. So they planned the date, she snuck the keys from work, and here he waited for her to arrive.

"'Sup Fluffy-buns!" Dina's voice cut through the night like a knife, startling the firey fox with its close proximity. He was so deep in thought he hadn't even noticed the Nidorina approaching, or that she was at his side already. "I hope I didn't keep ya waiting too long. The bus was late, and then I realized I forgot my bag at home, so I had to go back to my apartment, and then-" She kept talking, as she tended to do, while fiddling with the keys and unlocking the glass double doors. Vee followed her inside and then waited patiently near the training mats at the center while she turned on the lights, joining him soon after. "Oof, so, here we are. Still can't believe you said yes to this." She giggled, resting her hands on her broad hips and smiling over at the fox.

"Honestly? I can't either." Vee tries to downplay his nerves with a little chuckle, but it's definitely the kind of chuckle a dude about to get whacked in the nuts would make. He stood awkwardly opposite Dina, one hand grabbing his other arm and his tail flicking about low to the floor behind him. He glanced furtively around the empty gym, up at the ceiling, down at his bag, and then finally managed to get his eyes to settle on Dina. Who, of course, was still grinning ear to ear. She was loving this already! She's always thought Vee was a little cutie, never more so than when he was nervous to do something. She let his nerves build up a little bit more before she finally broke the awkward silence, dropping her back to the floor with a *whump*.

"So..." She began, tapping her foot idly on the gym may. "Guess we should lose the clothes, eh?" She smirked, and got just the reaction she wanted from her bud, an adorable little squeak. Fuck he's cute... She shook her head and began to strip down, pulling off her exercise top first and letting her sizeable breasts flop down into the open. They were each a pleasant handful, a pale white like the rest of her abdomen, and capped out with perky, dusky nipples. Vee was clearly staring, and though she wouldn't mind dragging this out to tease him some, she did want to get to the business at hand. So, she hooked her fingers around the waist of her leggings, and yanked em on down, giving Vee his first look at his best friend's lady bits. She was a rather bottom heavy gal, with thighs like tree trunks that squished together wonderfully, perfectly framing her snatch with cushy blue goodness. Though, the real star of the show was her ass. It was... well... thiccc. Two C's weren't enough to truly grasp the immensity of that bright blue donk. Now fully naked in front of the blushing fox, Dina cocked her hip to the side and crossed her arms beneath her breasts. "Well? I can't smack your nuts if I can't see em. Drop the pants, chop chop."

Vee just kinda.... kept staring. It was sort of a lot of process for him. Like, he'd always wanted to see Dina naked. What horny male 'mon doesn't fantasize about sneaking a peek at their stacked lady friend after all? And so, finally treated to the sight of those wide hips, broad thighs, and perky tits, he found himself Paralyzed, able only to keep his jaw from dropping open and embarrassing himself too much. Eventually though, some part of his brain reminded him of the reason that he came here, and also that Dina was looking at him kinda funny, and that was enough for him to snap out of his boob-induced stupor.

"Huhwhat? Oh. Right. Yeah. Pants." He got a giggle from Dina, who could see him blushing even past his dark brown fur.

"Yeah, pants. Gotta practice like it's the real deal, so no pants allowed. Plus I'm starting to feel kinda awkward being the only one with my junk out." She teased.

The Vulpix blinked a few more times and then slowly moved his hands down to pull off his shirt, and then undo his belt. He paused with his fingers around the hem of his pants, eying Dina somewhat warily. Because she was eying him back. Very intently. Apparently she's been wanting to see some naked foxy for awhile too. "What are you waiting for fluffy-buns? Forget how pants work?"

The innocently posed question was delivered with enough conviction, Vee knew there was an order underneath it all. So he sighed, and tugged his pants down, kicking em away and blessing the gym with its 2nd naked patron of the night. He had to resist the urge to cover himself up, keeping his hands behind his back, unconsciously just presenting his package to the now very interested Nidorina.

She whistled, and he saw her eyes focus on his lower half, a sly grin on her face. "There they are! Fluffy-Buns' fluffy bits. The ol twig n' berries. The stick n' sack. The uh... Veenis? And... Vee...balls." She snickered at her own words, stepping closer to the nude fox to get a better look at his exposed male-bits. He shifted uncomfortably from foot to foot, which just had the unintended side effect of making his junk jiggle and wobble all the more enticingly for her.

"Hmm. Kinda figured you'd be a lil bigger. You got that whole... hung twink vibe going on, but..." She suddenly dropped into a squat, face to face with his junk and rubbing her chin thoughtfully. "...you're kinda just a twink, I guess." It was true, Vee certainly didn't possess anything too special down there. His cock hung limply, hanging a good inch or two down from his crotch, a dark dusky pink that stood out quite nicely from his fur. It twitched just a bit as Dina scooted closer, tilting her head and leaning in even more. "Ooh, you got some fat nuts though! Jeez!" She broke into another fit of giggles and nearly fell back flat on her ass. "Fuck man, you trade sacks with a Ponyta or somethin'?"

It was true- unimpressive peen aside, Vee was blessed with a rather plump set of nuts. They bulged out his dark furred pouch, a pair of Grade-A free-range farm raised eggs, propping up his limp cock and plump enough that he couldn't really hide 'em between his thighs. They didn't hang all that low, his pouch nice and taut, as if his body wanted to present Dina with a nice steady target.

"Thanks, I guess? I didn't think they were that out of the ordinary but-"

"They're fat dude. You got some fat fuckin' nuts. For real." Dina grinned, taking a step back. "Speaking of which... how do you think we should start?"

All the color drained from Vee's face. Poor guy got so worked up with gettin' nude that he forgot the real reason they were both there. He fidgeted some more, his hands unconsciously drifting toward his crotch as a reflexive defense against whatever was to come. His sack pulled up even tighter too, if that was even possible. All of his squirming just served to amuse Dina, who was standing in a comfortable, confident pose, eying up her soon to be opponent.

With Vee's answer not forthcoming, Dina took the initiative. "I mean, how about we just start with a bit of boxing. Go for some punches-" Vee squeaked. "-orrrrr some slaps. Little tiny baby slaps." She didn't wanna spook him off too early after all.

"That's uh... that's fine. You just want me to try and uh, dodge, right?" He blinked a few times, and tried to adopt a bit of a combat stance, but balked from the moment his legs moved apart from each other and he felt his nuts start to hang in the open. Fuck, he never really considered just how vulnerable his bits were! They're just hanging there! Like a literal speed bag! Why the hell would Arceus make balls work like that?

"Yeah, yeah. Lil bit of bob and weave. I'm trying to practice attacking but that doesn't mean I want you to just be a punching bag. Gimme me a bit of a challenge." Dina giggled, cracking her knuckles and starting to bounce from foot to foot. "Ready?"

"...ready." He squeaked, and tried to emulate her stance, doing his best to avoid focusing on the sensation of his nuts swinging around down below. It was hard. Very hard.

Dina just nodded, and that was all the warning he got before she moved forward. She wasn't particularly fast, but her confident strides did surprise the fox somewhat. He quickly adjusted to the side, and then the other side, bouncing around as nimbly as he could so as to not present a good target for Dina. It was stupid, at least it felt that way, though he did manage to avoid the first few tentative swings from his companion. Just when he was starting to get a little more confident though, Dina adjusted her stance and threw her fist forward, a nice firm strike.

THWAP

"AGH, FUCK!" Vee squealed and stumbled back a few steps, going bow legged and jerking his hands down between his legs to cradle his balls, which just took a direct hit. Dina giggled excitedly- it wasn't the best punch, but it was the first time she had smacked a pair of nuts, and she could immediately see why her galpals enjoyed it so much. "Holy shit dude, I got ya good didn't I! Fuckin' felt em both on my knuckles, that was so cool!" She squealed excitedly, while Vee just continued to whine.

"Ngngh... yeah. Got em p-pretty dead on." Vee meanwhile was experiencing his first bit of punched directly in the balls pain. Which is distinctly worse than sat on a bike seat wrong pain or pants are too tight in the crotch kind of pain. This was real, proper, painful pain. And looking at Dina's excited expression, he could tell she wouldn't leave it at that. So, he bit back his mewling, stood back up, and got back into position.

The nidorina grinned wide, and was already moving toward him by the time he found his footing. She threw out a few more lazy punches, mostly warming herself up and trying to work the "first ball punch" jitters out of her. "Fuck, you're pretty quick." She huffed as he danced away from another blow, his balls bouncing merrily away from her fist. She squared back up with him, narrowed her eyes, and then deployed her next tactic. "Hey Vee. Check this out."

His quirk an eyebrow, and then squeaked in surprise as the Nidorina began to shake her chest side to side, bouncing her boobs to and fro right there in front of him! The poor fox fell right into her clever trap, that moment of jug-jiggling a distraction enough for Dina to swoop in, arm cocked back- and then released.

WHAP

Her fist connected squarely with his bulging nuts, and she could feel those rubbery orbs distort around her fist before flying back. It was a wonderful feeling- and she wanted more. So before Vee could even cry out in pain, she used her forward momentum and hiked her leg up, her knee aimed square between his legs.

Another direct hit! She slammed into him with all the force of a fat-bottomed freight train, her kneecap crashing into his sack and squishing it up against his pelvis. His bloated right ball managed to squirt out of the way from the impact, but poor lefty wasn't so lucky, and was utterly pancaked. His eyes shot wide and a sharp yowl of agony exploded from his chest, before he was mercifully carried backward by the momentum and tumbled down flat on his ass.

"ARCEUS!" He howled when he finally found his breath, his hands shooting down to cradle his agonized nutsack. Pain like nothing he had ever experienced before radiated out from his balls, both sharing in it, but his left nut quite a bit more. It already felt swollen, noticeably larger than his right testicle, which itself was plumped up a bit from the brief beating it had received. He could vaguely hear Dina giggling past the rush of blood in his ears, and when he could finally open his eyes he saw her staring down at him with her hand extended, grinning. "Got ya goooood~" Was all she could say.

He mewled weakly and took her hand, getting shakily to his feet. "F-fuck... why did you knee me..." He mewled, his voice high pitched and cracking slightly. The pain hadn't stopped, his left nut still throbbing with red hot agony as he stood there, trembling.

"Dunno! Just felt natural? Part of the move, y'know? I think that's a good combo. Punch into a knee?" She let go of his hand and took a few steps back from him, giving him some room to nurse his swollen babymakers. "Like, if this was a real match you woulda been done for! After that hit, you on the ground like that? I coulda stomped your stuff into goo before you even knew what happened!" She seemed way too excited at the prospect, and Vee could only whimper and try to keep those thoughts out of his head while he massaged his bruised beanbag.

"Urk... yeah, g-good combo. Totally coulda -nnhfm- got me with it." He managed to grunt out. The pain hadn't really subsided yet, but he felt Iike he'd gotten through the worst of it. That horrible throbbing agony had finally giving way to a less severe achiness, and the swelling seemed to have stopped once his nuts reached almost half again their usual size. "So... we're done now, right?" He days meekly, looking at Dina with wide eyes that were practically begging her to stop bopping his berries.

Dina gawked. "*Done?* We like, barely even started! C'mon, don't tell me those silly lil balls of yours are giving up after three hits!" She snickered, as if the idea of a man's testicle being that sensitive to a few measly punches and a single knee was the most ludicrous thing in the world. "I mean I know it hurts, but those things gotta be tougher than that right?" The Nidorina wasn't entirely sure they were, of course, as she didn't have her own pair. Still, it wouldn't make sense for nuts to be that fragile.

"They're like... really swollen n' stuff!" Vee mewled. "See?" With much hesitation, the vulpix removed his hands and spread his stance, letting his fat furry nutsack flop into the open air once more. He wasn't kidding- that pudgy pouch was looking a lot tighter and bulkier than it was before- those hefty hangers had swollen up a good bit, and his left was clearly outpacing his right, leaving the poor guy amusingly lopsided.

It didn't evoke any sympathy from Dina, who just giggled and waved it off. "Oh hush, that's not that bad. You can totally take a few more, I'm sure of it!" She got back into a fighting stance, and Vee did the same out of reflex. "Just a coooouple more smacks, and then we're all done. I got the ice pack ready for ya and everything." She winked, and he shuddered.

"Ugh, fine. Only a couple..." Against his better judgment, Vee acquiesced, and took his wobbly place across from Dina. He felt like his legs were turned to wet noodles, hardly supporting his weight and certainly not giving him the same level of agility he had earlier. So it didn't come as a surprise for him when, after a few stilted back and forths where Dina attempted to break through his meager defenses, she found what she wanted.

It came after a particularly wild swipe with her left foot, an attempt to trip him up, which he managed to dodge at the expense of his balance. A panicked yelp escaped him as his foot skidded on the mat and he dropped to a knee, only realizing the danger his spread legs presented to himself when he saw Dina's claws jolt between his thighs. "Dina, wai-eeee!"

Dina didn't wait, not a single moment. She saw her opening and she wasted no time in seizing it. *It* of course being the vulpix's swollen ballbag, which was now clenched firmly in Dina's hand.

"Ha! Gotcha!" She hissed triumphantly, flexing her fist harshly and relishing in the feeling of his swollen nutmeat squishing and contouring itself to her fingers. Vee was certainly not enjoying it, a high pitched mewl ringing out in the open gym and followed by a low, continuous groan as she began to pulse her fingers, tight and loose, each time sending a bolt of agony coursing out from his crotch. "D-Dina..." He mewled hopelessly, before a sharp squawk rose unbidden from his chest, the result of another harsh squeeze.

The Nidorina was utterly unconcerned with her buddy's complaints, far too distracted with the heavenly feeling of a pair of balls being distorted in her grip. She was really hoping she'd get the chance to be up close and personal with Vee's swinging scrote, and she wasn't going to let that chance go without fully... exploring her options.

"Hmm, I've always heard squeezing was a good way to incapacitate a dude. Just didn't think it was so easy to get in here!" She giggled, her ears twitching to the sound of Vee's whines syncing up to her rhythmic fist-clenching. "What do you think works better though? Just like, squeezing everything together like this?" She bunched her fist up tight, knuckles going white, little bubbles of squished fox-nut bulging between her fingers. That drawn out whine picked up a few octaves until it sounded like a damn siren, and then she finally relented. "Hmm, or is it better to just like go for one?" The nidorina adjusted her grip and tested her other hypothesis, wrapping his extra-swollen lefty up and giving it another white-knuckled squeeze. Vee's eyes bulged from his head, his cries picking right back up, his legs trembling with the unbelievable amount of pain that was emanating from his singular ball. It felt like it lasted for an eternity, but in reality it was only a few seconds before she loosened her grip. "Ooh, you should see the look on your face! That one's definitely the way go!" She gave him one final squeeze before she released his sack entirely, his brown furred nutbag looking rather bruised and battered at this point. His left ball was significantly larger than his right, a result of all the extra abuse it has suffered at her hands.

"Mmph, well, now my hand's kinda sore." She huffs. "So, I guess that means I can let ya off the hook now. Ya did good, Fluffy-Buns!" Dina giggled, and gave his swaying sack a playful swat, causing it to bounce between his thighs with an amusing *plop plap*.

Vee, who had just managed to get his other foot under him, howled all over again and tumbled onto his back, lying spread eagle and mewling weakly into the air. "My baaaaaaaaalls...." He carried on like that, whining and moaning, apparently refusing to get up.

"Oh stop bitching! You're fine dude! Just a little bit of swelling is all. Not like I broke anything... too badly at least." His left one did feel kinda... weirdly squishy. But that's probably a normal thing for swollen balls. Whatever. "I'll get your ice pack, just stop whining." She rolled her eyes and carried on giggling as she walked over to her duffel bag, shuffling around in it while Vee kept rolling on the floor and groaning.

"Alright alright, here's your ice." She made her way back over toward the quivering lump of fire fox splayed on the floor, tossing the ice pack up and down in her hand. As she approached though, she tossed it just a liiiittle too far forward. The Nidorina yipped and stumbled forward to try and catch it, and she managed to, but was already too far off balanced to recover. From the floor, Vee watched in a half conscious haze as the poison type babe stumbled in his direction, whirled around on her feet, and came tumbling toward him. He saw her approached like a Muk through molasses, time slowing to a crawl as the shapely female fell with her titanic tushy thrust toward him, those fat, quivering blue buttcheeks rocketing toward the mat- and right toward that unlucky nutsack of his. His eyes went wide as dinner plates, and he opened his mouth to yell something. But it was too late.

SPLURT SPLAT*

Dina's ass hit the floor, and the poor pair of plump spunkmakers under it were utterly destroyed by its impact. They flattened in a fraction of a second, and offered only the barest resistance before the bottom-heavy nidorina's ass crushed them into paste. It all happened too fast for either of them to process, Vee's eyes crossing and his mouth stuck open in a scream that wouldn't come out, and Dina just looking a little confused as she sat there.

"Oof, I'm fuckin' clumsy aren't I." She chuckled, and then paused, giving her fat behind a little wiggle. The poison type trying to figure out what the weird little jiggly... something, was between her cheeks. As she ground her butt into the mat, any solid chunks of nutmeat left in that empty sack were ground into goo, and that goo was further squished and squashed and mixed up. "The fuck am am I sitting on..." She mumbled under her breath, before getting to her feet and turning to survey her landing space.

"....oh. Shit." She saw Vee, legs twitching, eyes wide as can be, with a distinctly flattened lump of brown fur between his legs. The nidorina didn't say much for a moment, and then hesitantly poked her foot into Vee's deflated sack. Yep. Feels like jelly. Vee whimpered softly, looking up to Dina and down to his empty scrote, before finally passing out.

"Oopsie."

Vee fainted!

Dina gained 374 exp!

Dina leveled up!

Dina learned Giga Impact!
