Leo hated resistance training. Standing there, holding onto the ropes of the boxing ring as Abby let loose a series of uppercuts into his balls with her drills, pinning them against pelvis. Or having him stand against the wall so she could stab his ballsack into the hard brick, it was awful. It wasn't the only training they did, of course, but it was the one he dreaded the most.
 
But he needed that endurance if he was going to keep competing in the UL, and he had become much better at tolerating that uniquely male agony than when he started. In the four and a half months since he had first joined the Underground League, he was making great progress. If it wasn't for Abby's tutelage, he wouldn't have be doing nearly as well as he'd been: six wins!
 
Six females pounding his sack into the ground.
 
Six near neuterings.
 
Did it hurt? Abso-fucking-lutely. Was it worth it? Also abso-fucking-lutely.
 
Because it came with six different crowds cheering his name.
 
And six dick worshiping sessions with the Hannah, Lexie, and Blair.
 
Speaking of which, today was supposed to have been one of those sessions. The girls were there, standing in a semi-circle around him, but there was a noticeable lack of dick worshiping going on. His plums were incredibly sore from yesterday's match, (that Rhydon was fucking heavy), and they were begging to be emptied. So, it understandably made Leo quite annoyed when Abby told him that from now on they would have their endurance training sessions three times a week instead of two, starting today.
 
"You're going up in rank quite fast." The Beedrill had explained, "Your opponents are just going to get tougher and tougher, so your training needs to get tougher too."
 
Like most testicle-related things that came out of her mouth, he found himself disagreeing, but she managed to convince him in the end. His fights were indeed becoming more difficult, especially the last one. That Delphox he had fought in his second match was a chump in comparison to his last few opponents. He wasn't an newbie anymore, he was a real fighter, and that meant more intense fights and more intense training, the later of which Blair and Lexie were all too eager to help out with. Thus, he found himself backed into the corner of the small boxing ring.
 
"Thanks again for the assistance, girls. Being a Beedrill, I don't really have the proper anatomy to do these next few exercises very well, so I appreciate the help."
 
Blair smirked, cracking her knuckles and ogling the male up and down, "No problem, Abby. This is gonna be fun."
 
Leo usually loved the Lopunny giving him that look, but now it made him want to cover himself. "About that: what kind of 'exercises' are we doing, exactly?" He asked. "You didn't specify earlier."
 
Floating closer, Abby answered him. "One of the most common ways a pair of nuts gets busted is through a good-ol smack, so we're gonna do some basic kick and knee workouts. I'm sure you'll agree: being able to take a drill to the plums is all well and good, but it's not the same as a foot or tail or what have you."
 
Lexie cocked her head at this, "Yeah, how come you can take twenty-something hits from Abby but one kick from that Rhydon chick just crumpled you? You get distracted looking at her tits or something?"
 
The male gave an annoyed huff, but Hannah, who up till now had been silent, was quick to defend him. "Hey, that's not fair. She was twice his size, any guy would have been knocked down by that, its not his fault." 
 
Leo smiled at her support, but the Zeraora didn't understand, "Maybe, but I don't see the difference. I would've thought the pain just kinda blended together. Is a kick really that different?"
 
Leo shook his head, thinking, "Uh, yeah actually. Abby's drills are kind like, uh ... 'concentrated,' I guess is the word? It's like a big stab right in one little area, while feet and knee hits are more, like, spread out. They lift you off the ground, knock you off balance, but you don't feel it as sharply. Both hurt, but it's a different kind of hurt, if that makes sense."
 
Abby nodded, "That point of 'a different kind of hurt' is exactly what this session is about. I've realized that we've been too narrow focused up till now. Straight up pain tolerance isn't all that goes into being able to take a hit, you gotta learn to keep your balance, to roll with the punch. Trust me, I've been doing this long enough to know. Therefore, I think it would be smart to start training you to endure other sources of ball-related trauma. And since this is the first time we're doing this, we'll start simple, with you holding onto the ropes as usual. And that's were you two come in."
 
She swept her arm at the girls, moving to the side. Her apprentice made a show of rolling his eyes, bemused that Abby thought she could at all know what 'ball-related trauma' was like. Readjusting his grip, Leo sighed, "Whatever. Just... go a little easy on me, yeah? I'm still sore."
 
"Of course, wouldn't wanna break anything. Y'all ready?" Abby asked, turning her helpers. With a smile that made him slightly uncomfortable, Blair sprang into position in front of him, clapping her hands together like a giddy schoolgirl. As was typical, the Lopunny's ample chest bounced as she skipped forward. It was a sight that always got his attention, aided by the fact that her height meant he stood at nipple height. Legs planted, arms wrapped around the ropes, and tail curled around the padded corner pole, he tried to mentally prepare himself for what was to come. It wasn't that he wasn't used to being this position, but he usually had time to rest between "workouts."
 
Accepting his fate, the Luxio sucked in a breath. "How many?" He asked, despite not wanting an answer.
 
The bug-type thought for a second, rubbing her chin, "Well, it's the first time we're doing this, and you just had a match yesterday, soooo ... let's start easy and say ten each? You think you could handle that?"
 
"So twenty hits? I mean that's about what we usually do. Well if ... oh fuck it, fine."
 
Blair giggled, patting his chest, "Attaboy, always so brave. And don't worry, we'll still be sucking you off. Maybe I can even sit on your face like last time?"
 
The male's ears perked up. "Yeah? I definitely wouldn't be opposed to that."
 
"Alrighty then! Just try not to fall, okay?"
 
With that encouragement, the blue-furred electric-type spread his legs out all the way, giving the female a clean shot at his kitten-makers, which hung unprotected, as if daring her to hit them. The brown bunny began lining up a kick, tapping his jewels with her toes, making them bounce. He couldn't bring himself to look down. Getting his coconuts cracked was one thing, but actually seeing them get squished against his pelvis made him nauseous, so he settled on locking his eyes on her chest. Letting his blue nuts rest atop her fuzzy foot, the Lopunny hesitated for a moment. Cocking her head at Abby, she questioned, "You want us to go one nut at a time, or go for both?"
 
"Both. I've seen your kicks girl, better spread out the force and not take the risk." Abby replied.
 
That did little to inspire the male, who audibly gulped, "Arceus, they're gonna be hurting tonight. Ugh, lets just get this over with."
 
~SLAP~
 
"AGH! Fuck!" Leo hissed as the dull ache coming form his lower half suddenly turned into a blast of pain. The females cream-furred foot came up with the force of a sledge hammer, completely flattening both balls against her foot, going from ovals to pancakes. His body bent forward, pulling down on the ropes, but quickly leaning back up. It wasn't the first time she'd whacked 'em, but she still releveled in the sensation of those lovely blue orbs squirming against her toes. 
 
"Damn Blair, what happened to holding back!?"
 
The female was already lining up another attack, "I am holding back silly!"
 
~SLAP~
 
"AH! GIVE ME A SECOND AT LEA-"
 
~SLAP~
 
As the gals boy-toy's tenderized plums feel back down, they had less than a second to attempt to re-inflate before the Lopunny's foot smashed into them again. Though the impact was spread out between both jewels, her kick was still strong enough to force both of the male's marbles into his pelvis. The feeling of those quivering, rubbery organs molding themselves against her toes was something he could never get used too. It didn't help that Blair's foot reflexively stiffened from the impact, her toes pinching the blue bubbles of nutmeat squishing between them, making them bulge out just that tiny bit more. This third blast of male agony made his legs start to bend at the knee, his head pressing down into his chest. Earlier this year that hit would've completely floored him. A small part of him wished it still did, because then maybe Abby would end the session early.
 
He really couldn't say whether he preferred this or Abby's drills. Blair lacked the controlled restraint that the Beedrill had, however this was probably much less likely to accidently pop a nut. But then that was the question he always asked himself. Was it better to lose a nut, but only get hit once, or keep the nut, but have get hit over and over? Did he even want to know?
 
Pulling himself back upright, Leo slightly crossed his legs while looking up at the Lopunny's face through the strands of black hair that had fallen to cover his golden eyes. "Ohhh ... t-that ... mmhh ... i-it doesn't r-really feel like ... ughh ... like you're holding back."
 
Blair's foot was prepared to unleashed another kick, but relaxed as her smile shrunk. "You need to stop?"
 
Something pressed against him from behind suddenly, and he was surprised to find Hannah standing behind him outside the ring. The Gardevoir was tempted to give him a few encouraging strokes, but knew he would almost certainly blow his load right away, and they just couldn't have that. Instead, she settled on pulling his head back against her breasts and wrapping her arms around his waist. With a kiss on the cheek came a whisper, "You got this, Leo. Just get through this, and I'll milk every last drop outta you, you handsome little Luxio." The male shuddered in anticipation, standing up a bit more steady. He just wanted to melt into her touch, even if he wouldn't be able to stand back up if he did. Still, the visual was good enough. The feline silently thanked her, trying to ignore the waves of pain from down below. 
 
Spurred on by Hannah's promise, Leo gave Blair half-hearted chuckle through a wince, "Heh, I've had worse. Just not used to doing this right after a match, is all. It'll take more than this to get me to tap out." 
 
"Oh really?"
 
~SLAP~
 
"Oooofu-uck.
 
As if to test his boasting, the bunny began to rapid-fire alternating kicks into his groin as if she was juggling a ball. She wasn't quite strong enough to keep him airborne, but his legs shook slightly more with each sharp smack, causing him to inadvertently thrust his hips, his denied cock slapping against his stomach as his feet hit the ground again. Not that Blair was paying attention, her eyes were locked to the two orbs just below it.
 
~SLAP~
 
Lexie and Abby nodded approvingly at each kick, but Hannah was blushing so hard her cheeks were almost solid red. She loved pleasing dick, and dick pleasing her, but smacking around testicles just wasn't her thing. She would be lying if she said Leo's moans and the way he was squirming in her grip wasn't at least a little hot. But she really wasn't a ballbuster at heart, at most she'd give a teasing pinch every now and then if Abby needed her too.
 
~SLAP~
 
~SLAP~
 
Still, watching this, and his matches, she couldn't help but feel slightly turned on. The way he refused to fall down and give up, it was sexy in a way she couldn't explain. He was so vulnerable, yet so strong at the same time. Every slap or squeeze he took only ever increased her desire to comfort him, until she was just as excited for their after match "healing" as he was. 
 
~SLAP~
 
~SLAP~
 
It helped that he was so cute. Unlike her friends who were much more interested in either just fucking or busting him, Hannah really enjoyed hanging out with Leo outside of the gym. After his third match she had volunteered to walk him back to his apartment, which ended up turning into a regular thing as they started talking more. Most of their conversations were centered around his junk in one way or another, but as time went on this talking evolved into shy flirting. The other two girls didn't seem to notice, but Leo told her that one day Abby had pulled him aside and said that, while they can do whatever they want outside the gym, he's still not allowed to cum between matches, else it mess with his training.
 
Not that they had done anything. Even if she had already sucked him off several times, building up the courage to make a move on each other while alone wasn't as easy when there wasn't their naked friends taking the initiative for them.
 
~SLAP~
 
"GHHSSSFUUCK STOPSTOPSTOP!"
 
Leo's hiss lowered to a groan as his stance lowered into an unbalanced squat, his tail loosening and dropping to the floor. Blair had been going so fast that her last kick was inaccurate, slamming directly into only his left nut, rather than between both. Without the added cushioning, the unlucky ball gave little resistance flattening out against his pelvis. It was moments like these that made Leo understand why Abby insisted on not letting him orgasm before a match. Had his nut not been so full of seed, it probably wouldn't have been spongy enough to take that kick without some damage. 
 
Of course, had that happened, the League's Pokécenter could have easily healed it, but that would mean going even longer without getting off. Thankfully, though, lefty bounced back, if slightly more swollen than its twin.
 
Watching Hannah attempt to pull him back up, Blair bit her lip guilty, "Ah shit. Sorry dude."
 
"What happened!? You okay?" Abby gasped, nervous Blair had gone and popped one.
 
The male groaned, but didn't release his grip on the ropes. "Uhnn, A-arceus. You only g-got the left one that time."
 
"Oh, that's all? Should I give righty another to even it out?" The Lopunny teased.
 
"Absolutely not!"
 
"Oh relax. I'm just joking. You don't gotta be so serious all the time."
 
Abby was quick to buzz forward before Leo could reply, "That's enough, Blair. We decided ten and that was ten." She began to motion to the Zeraora, but stopped, turning back to her apprentice. "Uh, you good to keep going, or do we need to call it here?"
 
Her apprentice took a breath, looking up at the ceiling. Being milked dry sounded very appealing right about now. "No, I-I'm fine. Let's just ... oh Arceus ... let's just finish this already. Y-you know, sometimes I think you four want to pop them."
 
Hannah noticed the slight hesitation in his voice. Pulling him back into their hug and rubbing his chest, she raised an eyebrow. "Are you sure you don't need a break? Your legs are practically vibrating."
 
The Luxio closed his eyes, but nodded, trying to ignore the pain and focus the fairy-types gentle hands and sweet smelling perfume. "Why do I have to be so stubborn?" He wondered to himself.
 
The Beedrill replied with a shrug. "Hey, you know your balls better than us. You're up Lex."
 
More or less shoving the Lopunny aside, the electric-type wasted no time grabbing his shoulders more roughly than needed, silently looked him in his golden eyes. She'd been wanting Abby's permission to do this for a while now. Readjusting his grip on the ropes, the male nodded. Lexie was smaller than Blair, so surely she wouldn't hit as hard (or at least, that's what he hoped). Shifting her stance with a wiggle of her hips, she didn't bother lining up her attack, just ramming her knee straight forward.
 
~SMACK~
 
"One."
 
"NRRG! 
 
~SMACK~
 
"Two."
 
"GUHHH! Arceus, m-my nu-"
 
While Blair's snap kicks were quick enough to let his balls squirm around her feet, the Zeraora's knee completely took up all the space between his legs. His berries had nowhere to go, allowing her to put even more force into each hit while pushing down on his shoulders.
 
~SMACK~
 
"Three."
 
"HHHRRRGG!"
 
Testicles were so oddly interesting to her. Just watching them squirm and move around was so cool. She always found it funny how just a tiny bit of pressure on this things can make a male cry, yet they just swing there unprotected. It was almost like they were designed to be popped.
 
~SMACK~
 
"Four."
 
Leo's legs began to buckle, sending him sliding down the corner pole until Hannah stopped him. Lexie, seeing this, moved closer, pressing her chest against his and letting him rest his head on her shoulder. Switching from hitting his sack from her knee to her thigh, her fur helped to cushion the impact, but only by a tiny bit. One of his hands let go of the ropes to grab her waist for support. His hand reflexively tingled with electricity, but the female, being an electric-type herself, didn't really notice.
 
Hannah wasn't strong enough to keep him from falling, but the other female was able to grab him from under his arms in time. Still, the force from the last knee had knocked him off the ground for a split-second, and as she had yet to withdraw her leg, all his weight was now placed on his agonizingly flat testicles. His attacker shivered for a second as the rubbery sphere's squirmed against her thigh, forcing a small shot of pre-cum to trail across her fur, it felt just a lovely as she'd imagined. Taking a moment to enjoy the feeling, she mercifully lowered it, surprised to find him still not falling down.
 
After a moment passed without another hit, Leo, against his better judgement, committed to his stubbornness with a hoarse voice. "K-keep going. I-I-I can take it."
 
Lexie didn't argue, just chuckling while drawing back her knee. "You know, sometimes I think you want us to pop them.
 
~SMACK~
 
"AH FUCK!"
 
If she kneed him one or fifty more times, he couldn't tell. The deafening ache and horrible nausea coming from his groin was starting to blend together. It was something that usually happened after a while, being unable to tell one hit apart from another. In a strange way, it was almost a blessing. The agony continued to grow with each smack, until at last:
 
"Ten!"
 
With these words the male released his iron grip on the ropes, slowly bending to his knees with the two girl's help, careful not to have them touch the sides of his legs. Placed on his side, his hands shot down to cup his blueberries, one in each hand. His star-tipped tail unrolled from the bottom rope and slapped against the floor, looking almost dead. Eyes closed, legs crossed, and ears folded back, it was a position he assumed at least twice a week. His cyan eggs were swollen a good bit and stung when he touched them, but nowadays that was pretty usual. (Un?)fortunately, he didn't pass out anymore. 
 
Hannah rushed into the ring, rubbing his back. Meanwhile, Abby buzzed in place happily, "Good job Leo! Maybe next time we try without the ropes."
 
His brain could barely comprehend what she was saying. His nutsack felt like it was on fire, but he hadn't fallen. This wasn't the worst pain he'd been in, that honor went to his first match against Abby, but it was close. And yet, thinking back on it, he felt a strange sense of pride. When he first started a single hit nearly took him out, but now he had taken twenty hits after a match, and still hadn't fallen. Granted, Hannah was helping to hold him up, it was mostly him. He was still a far way off from becoming a champion, but at the rate he was getting better, he knew he could do it one day.
 
"You still conscious? I needa check your nuts."
 
The Luxio was torn from his thoughts by the Beedrill gently poking his leg. Carefully, he rolled onto his back and spread his black-furred legs, allowing his coach access to his genitals. He took a sharp breath, but he didn't pull away as her drill's began lightly tapping the top and sides of his orbs to make sure they were okay. 
 
The left one gave a tiny bit more to her touch than its brother, sending a tiny bit more pain through his body. His body flinched a little when she touched him, but he trusted her. He knew she wouldn't really hurt him, even if it was hard to remember that when her drills was buried deep into his nutmeat. Thankfully, she kept the ball abuse confided to their training sessions, though she wasn't above a rough poke or two when he let his guard down. She was a tough coach, and pushed his limits, but she wasn't cruel. She wanted him to become a champion, after all, and it would be kinda had to do that if she turned his marbles to mush.
 
He really was thankful to have her as his trainer. Her support and teachings meant a lot to him, especially after the way he had cursed her out during their match. He supported her career too. He went to all her matches, even if it made him a little conflicted to cheer for her whenever she pulped some poor dudes nuts. The sight always made Leo cringe, knowing just how easily she could have liquefied his plums when they had fought. Now, though, the female was finishing up her examination.
 
"Whelp, your left nut's a little soft. Er, softer than normal that is. But aside from that they seem perfectly fine." Abby said, placing a drill on his thigh.
 
Her apprentice gave a half-smile half-wince at the ceiling, "Yeah? Barely even felt it."
 
If the Beedrill could've rolled her eyes, she would've. "Let's not get cocky. But you did do great." Her gaze lowered back down to the dick bobbing in the air, "And I can see you want some attention now."
 
"Oh Arceus, yes please.
 
Pushing herself off the ground, Abby moved to allowed the girls access, "Have at 'em girls."
 
It took him a second to realize something was wrapped around his until-now ignored cock. Straining to look down, he found the Gardevoir's hand awkwardly pumping his length, as if not sure it still worked. It was a testament to how much he needed to cum that he already felt an orgasm building. He didn't even care how at this point. He hadn't had a release in three weeks, he needed this. Sure, he could probably just jerk off at home without Abby finding out, but the trio of gals were so good at handling his cock anything else just paled in comparison.
 
Leo began a moan, but was cut off by the Lopunny's soft round ass being planted on his face, his arms pinned down under her legs. Though tired, he was quick to get his tongue sliding over her clit the way he knew she liked it. He wouldn't say he as an expert by any means, but he definitely wasn't inexperienced. He'd pleasured some pussys and sucked some dicks before, he knew what he was doing. Blair's toes curled as his tongue worked as hard as possible, as if to encourage her to want to return the favor. It worked, she wanted to swallow his dick whole, but she also wanted Hannah to get her fun too, so she left it to her.
 
Slowly pumping his rapidly hardening rod, Hannah began to lean forward, but stopped herself. She thought back on Abby's words about him going against tougher opponents. None of them ever knew if the next match would be his last. What if this was the last time she saw him with both balls? What if she never got the chance to really have some fun with his dick? It'd been so long since she got some good dick, she didn't want to take the risk. She needed to feel it in her at least once.
 
Blushing and embarrassed, she looked up at the Beedrill for permission. "Hey, uh ... w-would you mind if I, uh ... you know... sit on it?"
 
Abby shrugged. She was in charge of Leo's training, but his rewards were entirely up to them.
 
"Well Leo, you alright with that?" She asked.
 
The blue feline's reply was an muffled but clearly enthusiastic moan.
 
"He says yes." Blair happily translated, wiggling her hips on his face some more.
 
The Gardevoir's eyes lit up, wasting no time in pulling up her natural dress like form and moving to straddle him. Lexie, wanting to watch as Leo entered her friend, dived to lay on her stomach between his spread legs, giving her a perfect view of the action. As Hannah sat down, her now soaking wet lips spread themselves over his twitching dick. In an almost agonizingly slow fashion, she slid her pussy down, all the way to the balls, before sliding back up, all the way to the very tip of the head, which was letting out a heathy amount of pre-cum. She closed her eyes, concentrating on grinding her clit against the shaft, making it just as wet as her.
 
Leo's moans became even louder, which had the side-effect of making the Lopunny moan louder as well as her orgasm approached. He wanted so badly to push himself inside her, his hips thrusting desperately in need. If his arms hadn't been pinned down he would have grabbed her shoulders and slammed her down on his cock in one swift motion, something Blair had expected and prevented. After three weeks of little to no stimulation, his cock just couldn't take the teasing. He needed to feel her now.
 
Fortunately, Hannah thought the same, and oh-so slowly slid forward more until her pussy was pressed against his stomach. The Zeraora quickly wrapped her hand around his eager rock-hard rod, helping to aim and guide it in, her other hand snaking its way down between her own legs. Biting her lip, the Gardevoir moved backward, allowing his dick to effortlessly push into her wet and waiting cunt. Lexie grinned as the head disappeared inside her, which was quickly followed by the shaft as the female kept sliding back until the entirety his cock was nestled snuggly inside. It seemed almost a perfect fit, his dick the exact right length for her.
 
With a little wiggle, Hannah sighed deeply, placing her hands on his chest for balance,"Ooh ... t-this-s is ... ooooh f-feels ..."
 
The Lopunny's right hand reached out to lightly grab her chin, forcing Hannah to look her in the eyes.
 
"Words, girl."
 
The fairy-type gave a dumb smile, "It feels so fucking good! Fucking ... oh why did I wait so long to do this is?"
 
Blair giggled, having never heard her friend swear before. "This isn't your first time, is it?"
 
"N-no, but ... oh Arceus, I never had a dick this fucking nice."
 
As the female said this she began to bounce up and down, just a little a first, but gradually building up speed until her ass was smacking down with a steady rhythm. 
 
Lexie, meanwhile, was content to watch the Gardevoir's cute butt bouncing up and down. Each wet slap making her cheeks jiggle as his glistening rod, which was now completely soaked in her juices, would reveal itself for a split-second before disappearing back into her pussy. It wasn't as much jiggle as Blair or Lexie, since she was smaller than them, but it was still more than enough to make the Zeraora purr in appreciation. Abby's eyes, though, were locked to his nuts. They looked so defenseless. It was an incredibly tempting sight, but ... no, he deserved a little reward for his hard work. Maybe next time.
 
As the minutes passed, Leo tried to hold back, to draw it out a little longer, but it was just too much for his dick to take after being denied this long. He was worried Hannah would be mad if he climaxed inside her, but she kept bouncing on his on lap, not slowing down for a second even as she felt Leo's dick fire off shot after shot of cum into her. The warm feeling of his seed filling her was what finally pushed the fairy-type over the edge, her pussy squeezing even tighter around him as they rode out their orgasms together, his cum mixing with her juices to act as lube for her bouncing. Though his tongue continued to pleasure the Lopunny, Leo let the rest of his body go limp, letting Hannah make good on her promise to milk him dry, all thoughts of nutpain forgotten. 
 
Exhausted, Hannah leaned forward to grab Blair's waist, burying her face into the bunny's wonderfully soft and fluffy bosom as her climax leveled off over several long moments after his had ended. 
 
The Lopunny smiled, running her hand through Hannah's green hair, "Don't tell me your done already."
 
Her friend let out a long, labored, heavy sigh of pleasure while pressing the Lopunny's tits against the sides of her face as she looked up at her. "Oh Arceus no. I just need a second to catch my breath."
 
Grinning, Blair turned to Abby. "How long do we have the gym for again?"
 
"Little over two hours." The Beedrill replied, her gaze transfixed on the lines of semen leaking out of the Gardevoir and sliding down her apprentice's cock.
 
Hannah began to speak, only to be cut off by Blair pulling her into a kiss.
