Leksi, a young squirrel girl, had become a rising star at her local dojo. Despite having only joined fairly recently her nimble footwork, quick strike and tendency to aim low had made her a formitable opponent for her all-male class. She was more than willing to take on any challenge thrown at her, confident in her ability to get out of any tight spot with one swift kick to her opponent's dangling weak point, and that confidence only made her that much cooler in the eyes of the boys around her. She'd never openly brag about it but the status had kinda gone to her head and every week she looked forward to her afternoon at the dojo.
Arriving a little later than usual, Leksi walked into the dojo's single locker room that was already half filled with boys changing into their training gear. Her arrival turned a few heads and she was greeted with friendly smiles and waves from the familiar, mostly naked, group of guys. She returned the wave and set about to changing herself. There was still something exciting and naughty to her about being the only girl in the room. Nobody made a big deal out of it, but she knew, or at least dearly hoped, that a lot of the boys would be trying to steal a few glances of her stripping off her school outfit. She certainly was guilty of doing the same to them. She could feel herself getting wetter by the second as she pulled off her panties and stood there for a second entirely naked, 'accidentally' letting anyone catch a good look before she put her gi on. Not that that changed much, given how the training outfit was just a large-sleeved top. The sensei said it allowed for more freedom of movement that way. Nobody really questioned it.

With her change finished, she turned around to take a quick look around before heading out to the dojo floor, and noticed something new across the room. A big set of fluffy balls hanging under a fluffy ringed tail. Moments later she noticed the rest of the new boy too. A raccoon, a little taller than her, with a serious, almost intimidating face. He looked like he meant business, and she was immediately curious from how much he stood out among the others. Just to be sure, she glanced over to the fox boy on her left. He had always had the biggest equipment of anyone in the locker room, and had played a part in many of her fantasies. There was a moment of relief in her head as she confirmed this was still the case. The raccoon had a big set of nuts, sure, but the fox was still king where it mattered. She'd probably be seeing both in her dreams tonight though. Satisfied, Leksi walked out of the lockers and was soon followed by the rest, including the raccoon who went directly up to their canine sensei and gave a bow. The sensei returned his greeting and turned to the rest of them, his stern voice cutting out any remaining chatter.
"Alright everyone, this is TJ, he used to be in my other class but broke his leg so he was out of commission for a while. Dont go too easy on him. Now lets get started!"
As ever, up first was a bit of stretching. Leksi's eyes wandered around as everyone started. Knee up to the chest. Reach down and touch the floor. Switch sides and repeat. Ten jumping jacks. Her heartbeat was already picking up and not because of the jumping. No matter where she turned her head she could see dicks and balls swinning, bouncing, swaying and shaking, shamelessly giving her the show of a lifetime. She bit her lip a little, drinking in the sight until she was rudely pulled back to reality by a painful whap between the legs from the sensei.
"Focus. You're falling behind."
He wiped his hand but said nothing more. He didn't need to. Looking down she realised she had started dripping a little on the floor. She swallowed and nodded, quickly returning to her jumping jacks, doing her best to subtly wipe the few remaining droplets away with her foot.

With warming up done, it was time for a round of one on one sparring. Leksi already knew perfectly well who she wanted as her opponent, and quickly headed over to the new guy.
"TJ, right? Lets go!"
She put on her best fighting pose and flashed him a confident grin. His reaction caught her off guard a bit however. The other boys would usually banter something back, put a little flair into their stance, have some fun with it all. But not TJ. He gave a silent nod and snapped into a well practiced stance, staring her down. He was actually serious about this. Delighted by this whole new kind of opponent, Leksi went in for the opening strike and was surprised again by how nimbly he evaded her. His motions were fluid but decisive, his body moving its weight around with ease using his fluffy tail as balance as he brushed her strike aside, grabbed her arm and threw her down. Had it not been for her own great sense of balance and quick feet she'd have ended up face first on the floor, but she managed to catch her fall and recover, skidding back onto her feet as he returned to his stance, ready to go again. For a second she just stood there trying to get her bearings. She was used to being the faster one in any match, needing only focus on quickly striking and evading. Now, for the first time, she was up against someone equally quick. She didn't have long to think it through because TJ was already on the attack, his palm strike just barely missing her face. She leaned back to avoid it clipping her nose, but failed to see his leg sweep coming. She suddenly found her footing greatly compromised with one leg kicked out from under her, and flashed her wide open pussy to everyone looking in her direction as she tried to correct her stance. The raccoon spun around and tried to land a spinning kick on her chest but she ducked in the nick of time like a hero in a kung fu movie. By now their energetic match had gotten some attention from the others, a few of the boys having paused their sparring to watch. TJ was still laser focused, quickly stepping back as Leksi took a swing at him in turn, ready to counter her next punch. This presented an opportunity, and it presented a juicy set of targets for her foot too. With momentum from her missed punch Leksi swung her foot up as hard as she could, her toes impacting the bottom of the raccoon's testicles with a hefty thud.

There was a gasp from the onlookers as sympathy pain stung their boyhoods, but it was nothing compared to what TJ was feeling. His legs turned to jelly and he slowly sunk to his knees, then fell on the floor and curled up, whimpering and gasping as his battered balls sent shockwaves of pain through his gut. His eyes watered and his mind went blank as he cupped his balls. It wasn't the worst pain he had ever felt, that title still belonged to his broken leg. But it was different. Horrible, yet strange. His body ached, his breath grew short... and his dick started to get hard.
The sensei pulled him up with a sigh, sending him to the back rooms
"Go put some ice on it and walk it off. The rest of you, round 2."
Leksi's heart was still racing. She wanted to run off and masturbate right now while she could still feel his balls on her toes. She wanted to fight him again to feel that rush of a close victory.  But first she had to deal with the rest of the lesson. Her next opponent was the lion, his stronger but slower frame a piece of cake for her to run circles around.She playfully slipped past his first attack and then tripped him, taunting him to get back up. As he did, she feigned a kick at his jewels to make him flinch and dodge, then delivered a high kick to his chest knocking him on his back. She stood over him victoriously, knowing full well he was staring right up into her crotch given his bright blush. Behind her, the bunny got thrown on the floor hard, having fallen for the very attack she had barely managed to avoid. TJ was back from walking it off, and he seemed to have recovered well. He and Leksi locked eyes and when the sensei called for another round, they wordlessly agreed to a rematch.

They took up positions again, both now knowing what to expect from the other. Leksi knew she'd need to go for the low blow quickly and not let him throw her off, as he was at his most dangerous when he was in motion. She knew that because it was the same with her and she wasn't too happy about fighting her own shadow like this. As it had worked last time she took a swing at his face with her leg at the ready but he this time he was prepared. He ducked under the attack and grabbed her leg trying to throw her, forcing her to turn the kick into a lurching step. He tried to follow up with a kick of his own to her chest, but she managed to step back from it, getting an up close look of his balls as the swung past her. Hoping this was her chance she tried to land a punch on his crotch but he quickly backed off with a nimble spin and swung a backhand at her. She saw it coming a mile away. It was wide, obvious ...and a distraction. With her eyes focused on the big sleeve swinging past her face, she forgot to guard low and the raccoon took full advantage of it. The boy kicked up his knee into Leksi's unprotected crotch, the hard bone smacking right into her most delicate parts, mashing her clit as she was lifted onto one foot for a moment.
The pain was nothing like the last couple of times she had taken a hit down there. It was sharp and burning and overwhelming, taking all the strength out of her body as she fell over clutching herself gently, gasping for breath as her body sent every possible signal into her brain at once. Surprise. Pain. Panic. Confused arousal. More pain. More confused arousal. She rolled around on the floor hands tightly between her shaking legs as TJ caught his breath.
"...that's one each. We'll need a tiebreaker later." he said, panting a bit. The sensei came to pick Leksi up and had her sit the last minutes out with an icebag on her pussy as the other pairs finished their matches. Her mind was still a bit of a blur as she headed into the showers, just offering reassuring mutters and thumbs up when asked if she was ok. Feeling herself up under the shower she winced. Her crotch was more sensitive than ever and tingly all over, like the pins and needles of sitting on her leg for too long cobined with that weird tickling of a healing bruise. It was strange, yet not entirely bad. That only lead to further confusion in her head.
She kept glancing back more at TJ, who always seemed to be glancing right back, all the way to her leaving the locker after giving up on putting her panties back on after the third failed attempt. With the warm summer wind tickling her bare crotch under her skirt she started the slow, awkward walk home.
She had a lot to think about the whole way, and a lot to explore once she was back in her room.
