Playing Games with Bella

Colin and Bella had been part of the same friend group since middle school, and in their early twenties they still hung out regularly. Their other friends often made fun of them for spending so much time together one-on-one, and there had long been a rumor going around that they were sleeping together. In truth their friendship, while fairly flirty, was and always had been strictly platonic, even though Colin did find Bella super attractive. He even thought about her when he jerked off sometimes, although he felt ashamed of that fact and would never have admitted it to anyone. He salivated at the thought of their relationship becoming more physical, but he really didn't want to be one of 'those guys,' so he focused hard on respecting the boundaries of their friendship.

One summer day they were at Bella's house. Her place had no AC, so to fight the heat they had both stripped down to as little as seemed appropriate, Bella in a sports bra and compression shorts, Colin in a tank-top and some snugly-fitting boxer briefs. They'd been doing nothing for a while, but Bella had always gotten bored easily, and today was no different.

"Let's play a game!" she said. She had a childlike love for coming up with little 'games'; as far as Colin was concerned it was always the stupidest shit imaginable. But he didn't mind playing along.

"Okay," he said. "What's the game?"

Bella thought for a second. "Let's do a slap fight!"

"A what?" Colin asked.

"I saw it on Youtube-- we take turns slapping the other's face, and whoever gets KO'd first loses."

It wasn't the first time Bella had suggested something like this. Colin loosely suspected that Bella might be into getting hit, like in a sexual way, and suggested games like this for that reason. He wasn't into that kind of thing himself, but just the vague idea that Bella might be surreptitiously acting out her sexual kinks with him made his heart rate go up.

"Okay-- if you want to," Colin said.

"Yes!" Bella said. "Okay, stand up, and don't go easy on me 'cause I'm a girl-- I want to win fair and square!"

Bella went first. She brought her arm back and shot her palm hard into the side of Colin's face.

"Ouch," he said, rubbing his cheek, which was turning slightly red.

"Okay, your turn!" Bella said excitedly. There was no way he could bring himself to actually hit her hard. Even so, he winced slightly as he struck her and a brief moment of shock registered on her pretty face. Bella recovered almost instantly and grinned. "Okay, my turn again!"

They traded a few more slaps, but it seemed clear that neither of them was going to tap out. "Okay, next level: how about we trade punches to the arm," Bella said.

Colin flexed the muscles in his arm while Bella made a fist and punched his bicep. It didn't hurt much. When it was his turn, he only punched with about 50% force, but she grimaced in pain.

"Ow!" she said, rubbing her arm. "Charley horse!"

"Sorry," Colin said. "I can tone it down."

"As if!" Bella said. "Don't you dare." She collected herself and threw her body into another punch, but again it didn't have much effect. Colin played up how much it hurt, wanting her to enjoy the game.

As Colin lined up his next punch he was distracted; he wanted to avoid hurting her again but didn't want to make it obvious that he was holding back. He got caught in between and his aim was a little off. His fist grazed Bella's arm, but it also went off to the side and made partial contact with her left breast.

Bella gasped in mock outrage and held her chest, but her eyes were smiling at him. "Colin!" she cried, hamming it up. "That is not at all appropriate! There's no need to fight dirty, even if you know I'm going to win."

"I'm so sorry Bella," Colin said. "That was a total accident-- I did not mean to do that at all."

"Uh huh," Bella said, sticking her hand inside her bra and rubbing her breast, which Colin, despite his best efforts, couldn't help but watch longingly. "I guess I'll choose to believe you. Okay, back to it-- and no more dirty tactics, or else there will be consequences!" They traded a few more punches to the arm, but Bella soon got bored.

"Okay, how about stomach punches now-- that'll really separate the men from the boys!" Bella said.

"Err, okay," Colin agreed. He felt hesitant about punching Bella in the stomach, but he didn't want to spoil her fun.

"I'll go first," Bella said. "Lift up your shirt so I can get a clear shot." Colin raised his tank top, exposing his bare stomach. Bella reached back and punched hard right where his belly button was. It didn't have much effect-- Colin had a pretty firm layer of muscle there, and Bella's small fist couldn't punch so hard-- but he played it up to make it seem like it hurt more than it did.

"Okay, you go now," Bella said, bracing herself. Colin felt weird about it, but he planted his feet and punched her in the stomach with medium force. "Ooo," Bella moaned softly, holding her stomach. "Good shot."

They went back and forth. Bella's punches only hurt Colin a little, but feeling her hand on his bare midriff was making his skin tingle slightly.

"Okay," Bella said after a few more rounds. "Hit me somewhere I'm not expecting." She stood up straight with her arms out, looking at him with an expression of concentration.

Colin was about to protest that this was dumb, but decided it was easiest to just keep going along. Halfheartedly, but not too lightly, he kicked her in the shin.

"Ow!" Bella cried, grabbing her lower leg and hopping around on one foot. "You bitch! That hurts!"

"Well what did you expect?" Colin said, slightly annoyed. "Isn't that the point?"

"Ah, hard to argue with that," Bella said. She was rubbing her shin, but after a moment she stood up straight again. Smiling at Colin, she lifted her bare foot and tapped it gently against the pouch of his boxer-briefs. "Can I kick you here?" she asked, tapping her foot a couple more times against the fairly substantial contents of his underwear, to indicate where she was talking about.

"Uh," Colin said, feeling a jolt of adrenaline run through his body. "Why?"

"'Cause it'll be funny!" Bella said.

Colin had never really taken a direct hit to the balls before, just some glancing blows, none of which had been so bad. He knew that everyone talked about how getting hit there hurt, but he didn't really have a personal point of reference. At that moment it didn't seem like it would be that big a deal; he figured it would hurt some, but how bad could it be? None of Bella's other strikes to various parts of his body had landed with much effect. Plus, it was true that he had accidentally hit her in an 'intimate body part' earlier, so maybe it was only fair.

"All right," Colin said. "I guess that's fine."

"Sweet!" Bella said, her face beaming. "Okay, spread your legs just a little bit more so that I can connect nice and solidly." Colin did as he was told, standing upright but with his feet planted slightly apart, the outline of his package clear and conspicuous in the thin and tightly-fitting fabric of his underwear.

"All right, let's make this one count!" Bella said. She shifted her weight back to accrue momentum, bringing her right leg behind her and concentrating on her target, then shot it forward hard and fast, her leg swinging in a wide, efficient arc forward and up between Colin's slightly spread legs, so that her bare foot connected ultra-solidly with the soft pouch in his boxer-briefs with a sickening 'thud,' her foot continuing to drive forward and up even after the initial contact, burying itself deep in his crotch, intent on delivering the maximum possible punishment to the contents of his underwear.

Colin gasped and lurched forward, his knees buckling and his eyes rolling back slightly in his head. Bella slowly removed her foot, smiling with relish, and Colin crumbled into an agonized crouch on the floor, huddled over his body's center of gravity, which at this moment was unquestionably located in his balls. His legs were shaking and his muscles were spasming. His face felt red-hot as he gasped for breath.

It hurt so, so much more than he had expected. It felt like someone had struck the absolute center of his nervous system with a hammer. His stomach was in knots, he felt nauseous and dizzy, and his balls were sending pure, liquid waves of pain directly to his brain.

Bella giggled, clearly delighted. "Oooooo, got you good!" she said gleefully, clapping her hands quickly in excitement. "I told you it would be funny!"

Colin moved his mouth, trying to speak, but he couldn't make any sound come out. It seemed critical to communicate to Bella that this was truly, truly awful, and not at all the time for their usual playful back and forth; but the more she talked, the more it seemed that she understood perfectly well how miserable a fate she had subjected him to.

"Boy, that must have hurt SO much," she said, looking down at his crumpled form with her hands on her hips. "I got you right in the balls! It's so satisfying when guys crumple into a puddle at your feet after you kick their nads-- then you know for sure that you got them really good!"

"Oooohhhh," Colin moaned, his voice faint and high-pitched, as he rocked back and forth on his knees, his hand clutching between his legs, desperately and futilely searching for some way to relieve the agony.

"Don't you remember learning about this in health class, dummy?" Bella asked. "Your testes are soooo sensitive. They're absolutely loaded with nerve endings, so that even a quick little tap can send unbearable pain signals straight to your lizard-brain-- to say nothing of a good hard kick! They're made that way on purpose, so that a girl can hurt a guy really bad if she wants to, without having to try too hard." Bella laughed at her own explanation.

"Fuck," Colin choked out, his voice a hoarse, barely-audible whisper. "Oh my God. I--"

Bella smiled. She knew there was nothing that could make Colin feel better except slow, agonizing time, but there was no harm in pretending to help. "Here, let's get you into a recovery position," she said, guiding him onto his hands and knees, with his butt stuck out behind him. "I've heard some guys say that this helps relieve some of the tension in their lower body, after getting their balls kicked."

It wasn't her original intention, but after moving him into this position, it was too funny of an opportunity to pass up. The look of pure suffering on his face made such a stark visual contrast with the sight of him from behind, where, because of the angle of his hips, the pouch in his boxer briefs looked particularly big and full, the thin fabric clinging to his package, which was suspended underneath and slightly behind his butt.

Bella patted Colin's butt just above where his private parts were so exposed. "Sorry Colin, this is so mean-- but I just can't help myself." She matter-of-factly slapped her hand back and forth just beneath his butt, striking first with her palm and then in quick succession with the back of her hand, and then repeating the motion, battering his exposed testicles back and forth like she was waving smoke out of her face.

"Ahhhh!" Colin cried in tormented surprise. He tried to crawl forward out of her reach, but Bella threw her arm around his waist, easily holding him in place, as he was in such a weakened state.

Watching him flail and writhe in a fruitless attempt to get away, Bella giggled to herself as she continued to slap his balls from behind. "Just hold tight Colin, this may hurt a bit," Bella said, making herself laugh, throwing in a particularly hard smack now and then.

Colin was crying out with every slap to his ballsack, his voice high and girlish. "Ah! Ah! Ee! Eee! Oh! Ah! Ohhh!"

"Oh my God, you sound like a little boy!" Bella said, laughing in delight. She gave him an especially hard slap from directly behind, making sure her hand connected with the backs of his balls, which she had heard was a particularly sensitive spot; she wanted to see if she could get him to make sounds that were even more high-pitched and ridiculous.

"Eeeeeeeee!" Colin cried, as her hand found that ultra-sensitive spot and hit him there particularly hard.

"Oh my God, don't be so dramatic," Bella said, rolling her eyes, even though she had tried her best to elicit exactly this reaction from him. She went back to slapping back and forth horizontally across his scrotum, this time abandoning the steady rhythm and instead hitting with arbitrary timing and force, so that each strike came as a surprise.

"It's not a big deal to get your nuts worked over now and then, it's honestly pretty normal," Bella said. "Okay yeah, I know that guys are super tender down there after getting kicked in the balls, and all the nerve endings are even more sensitive than usual, so I *guess* in that sense it's kind of mean to give you a good old testicle-whacking while you're still recovering from a foot slamming into your nuts--" she gave his sack two quick hard smacks to punctuate her point; Colin sucked in air raggedly, overwhelmed by how exposed his balls were to Bella's cruel whims, and how little he could do about it-- "but, like, whatever. I guess sometimes I'm mean." She laughed. "Remember when you punched me in the boob before? This is just payback for that. So like, honestly, you actually totally deserve this." She brought her hand down between his knees and then smacked it up from below into the bottoms of Colin's balls six or seven times, causing his limber, wracked frame to tremble with each cruel moment of contact.

She kept at it for a few more minutes, batting at his genitals from behind like he was a plaything, and then eventually let go of his waist, so that he could crumple into a fetal position, moaning in pain as his whole body twitched.

"Okay, now we're even," Bella said. "Feel free to punch my boob again whenever you want, but then I get to have another go at paddling your nads!" She had actually done it just because she felt like it, and thought it would be funny, which it was-- but she was happy to pretend this had been her motivation the whole time.

Colin felt miserable. Being held in place by Bella-- and held in place so easily, without any real effort on her part, because of how thoroughly she had incapacitated him-- while she knelt behind him and smacked his unprotected balls around like it was a game, casually explaining the whole time how funny it was and how you should expect this sort of thing to happen from time to time if you were a boy-- that had been excruciating, humiliating, and demeaning. But seared into his mind, as if she had branded his consciousness, was the memory of that kick, which she had delivered so giddily. The knowledge that anything could be so devastating terrified him.

"Ohhhhh," he moaned weakly, regaining some ability to speak after a long time. "That hurt so much." He was still curled up on the floor, on his knees hunching over his own crotch.

Bella laughed. "I'll bet it did!" she said. "That's the whole point!"

"Ohhh, Jesus Bella. Why'd you have to kick me like that?"

Bella gave him a look that said 'are you dumb?' "Um, you literally said I could? Remember?"

Colin got up into a kneeling position, wincing and breathing gingerly. "Yeah, but you didn't have to kick me so hard."

Bella rolled her eyes. "Oh please, don't be such a baby," she said. "Obviously if you're gonna kick a guy in his ball bag you're gonna do it nice and hard. That's what makes it fun!"

"Ughh," Colin grunted, rubbing his crotch. "That was so awful."

Bella smiled down at him impishly. "I guess you've never been kicked in the balls before, huh?"

"Um," Colin said. "I guess not really."

"Yeah, that figures. If you had, you wouldn't have agreed to let me kick you there." Bella laughed again. "Well, I'm honored to be your first," she said, making a heart symbol with her hands in his direction. "I hope you'll think of me the next time a girl gets you really good right where it counts."

Colin slowly recovered, and they went back to sitting on the couch, scrolling on their phones. It wasn't long before Colin began to feel almost like the whole episode had been a weird and horrible dream. But after a while Bella turned to him.

"Okay," she said. "We've rested up, time for a new game."

"Uh, okay," Colin said.

"Okay, I got a great idea from earlier." Bella was clearly excited. "We'll do like the same format as the slap fight..."

"Yeah..." Colin said uncertainly.

"But instead of taking turns slapping each other in the face, we'll take turns punching each other in the crotch!"

Colin was silent for a moment, then scoffed. "Yeah, right," he said. "I'll pass on that one."

"Oh come ooooooon, Colin." Bella said, leaning over on the couch and falling against him, so that her body pressed into his. "Why not? It'll be so much fun!"

"What do you mean why not?" Colin said. "Because I don't want to get punched there."

"I mean, it's just for a game," Bella said. "You don't have to take it so seriously. And you'll get to punch me too, so it's fair."

"That's not fair at all!" Colin complained. "A girl getting hit in the crotch is not the same as a guy getting hit in the crotch."

"You don't know that," Bella said. "My pussy is pretty sensitive to even the lightest touches." She smiled at him mischievously and licked her lips.

Colin quickly got up from the couch; hearing these words come out of her mouth sent a white-hot electric current through his veins, and he couldn't bear to feel her playfully pressing her body against his at the same time. He stood facing her as she sat on the couch, a look of consternation on his face.

Bella looked at him calmly. "I mean, I feel like I can get you to agree, if I use the right negotiating tactics," she said.

"No way-- I'm not gonna do it," Colin said.

"I don't know, I have some pretty convincing negotiating skills," she said.

"Nothing you can say will change my mind," Colin said.

"Is that so?" Bella asked. "Let's see about that." With startling quickness, she snaked her hand up one leg of his boxer-briefs, felt around inside to orient herself within a second or two, and wrapped her fingers around Colin's bare ballsack, squeezing with medium pressure.

Colin gasped and started softly whimpering, not so much in pain as in fear. How much simpler life had been just a moment ago, when his balls were not in Bella's grip; how he'd taken it for granted.

Bella giggled. "I feel like this changes the tenor of the conversation, no?" She pulled on his balls to emphasize her point, forcing him onto his toes, leaning forward at an awkward angle. "After all, isn't it true that one could inflict significant agony with just a flick of their finger, if it caught you in the wrong spot?" She squeezed his nuts several times like a stress ball, making him groan in discomfort. "I've heard that before. Let's see how true it is."

She pulled the leg of his underwear aside, exposing just the bottom of his naked ballsack, where his sensitive testes were being kept firmly in place by the grip of her hand.

"Okay Colin, let me know if this makes you want to reconsider." She flicked her finger hard into one testicle and then the other, and then got each one again. Thwack thwack! Thwack thwack!

"Oh!" Colin yelped in pain and surprise, bending slightly at the waste and grimacing. It hurt a lot more than he was expecting it to. It was a tiny amount of force, but it was directed with such cruel precision at such a sensitive part. With his balls secured firmly in Bella's grip, there was no chance she would miss her mark even slightly; each flick of her finger impacted exactly where she meant it to, striking the highly exposed nerve endings in Colin's testicles.

"Eeeee," he whined in dismay.

Bella laughed. "Oh my God, I can't believe that hurts so much! It's just a little flick!" She snapped her finger into his nuts several more times; Colin groaned and bent deeper at the waste as the pain from each flick accumulated, his face scrunched up in agony.

Bella looked up at the expression on his face and laughed again. "Oh my God, you look like you have a terrible stomach ache. I guess this hurts, huh Colin?" She flicked her fingers into his nuts a few more times, then brought her hand back and gave him a hard slap across the bottoms of his balls.

"Oooooooo," he groaned, the sharp impact of her fingers sending new waves of pain through his body.

"So, are you ready to give in yet, or are my negotiating tactics not convincing enough?" Bella asked, sticking out her tongue at him. "Well, I guess your exact words were 'nothing I can *say* will change your mind,' so maybe I have to be more literal." She adjusted her grip on his nads. "So here's my offer: if you still won't say yes to the game, I'll squeeze your testicles really hard, and I won't stop until you change your mind. Sound good?"

Before he could respond-- and it would have taken a lot of effort to form words-- Bella made good on her promise, gathering his balls in her small hand and quickly making a tight, compact fist, like she was trying her best to close her hand while pretending there was nothing in it.

Immediately Colin knew he had to give in. He couldn't even think straight anymore, but whatever it was she was trying to get out of this, she could have it, no questions asked; he simply could not endure what she was doing down there. Within a second or two he was telling her that he agrees, he taps, whatever she needs to hear to stop squeezing. But to his dismay he soon realized that the words hadn't actually been audible; he was just moving his mouth with no sound coming out. He tried harder, but still he couldn't speak, and time was passing and passing with Bella's grip on his testes still relentless and unbearable. Becoming more desperate, he started flailing his arms, his eyes wide with terror, trying to get Bella's attention, but her focus was locked on his lower half, in full concentration. Eventually he managed to tap her on the shoulder, and when she looked up it was pretty clear what his intention was, even if he couldn't speak. She held on for a few more seconds and then let go.

Colin was in too much pain to even fall over. He just stood there, hunched awkwardly with his hands on his knees, extremely relieved that she had stopped.

"See? I told you I could be a convincing negotiator," Bella said, and laughed. After a little while Colin sat back down on the couch, holding his crotch absentmindedly and looking stunned.

Bella smiled at him knowingly. "Don't feel too bad Colin, that's to be expected. Whenever I get my fingers wrapped around a boy's balls, it's always lights out. Some guys are smart enough to tap out immediately, as soon as I get their sack in my hand. But when they're not, every time I've actually squeezed a guy's testicles really hard like that, he always caves super fast. So don't feel bad; it doesn't make you any less of a man."

Colin took some time to collect himself, and spoke shakily. "All right, you win; we can play your game. But I need some time to recover first."

"I suppose that's fair," Bella said, flopping back onto the couch and picking up her phone.

She let him rest for a long time, which he was grateful for. He wanted to wait until he was back to feeling totally normal, because he was afraid that if he got hit again while he was still so tender that it would hurt a lot more.

"Okay," he said eventually, standing up from the couch, satisfied that he had fully recovered. "So how does it work exactly?"

Bella sprang up and stood across from him. "Just like before. We take turns trying to KO the other person, but this time instead of face slaps it's all punches to the crotch. You go first!" She seemed excited.

Colin sighed. With all the pent-up suffering and frustration, he wasn't as concerned as he had been before about holding back. He reared his arm and punched hard right at the place where her legs met, which was outlined quite nicely by her tight compression shorts.

"Oof," she grunted and stumbled a bit, her eyes widening in surprise. "Whoa, you can punch hard," she said, rubbing her crotch with a faint grimace on her face. "That actually hurt." It didn't seem to Colin like it had hurt very much; she had hardly reacted. When his fist landed between her legs, he could feel so concretely how there was nothing there, nothing vulnerable that he could have hurt.

"Okay, my turn!" Bella said. She knelt down in front of Colin, her face level with the bulge in his underwear. She looked at it for a moment without doing anything, then made a fist, cocked her arm back, and delivered a vicious uppercut right into his protruding package.

"OOOOooooo," Colin cried. His knees buckled and his legs turned to jelly, he fell forward onto Bella, who held him up for a moment so she could look into his face. His eyes were watering and he looked like he was trying not to cry. Bella laughed and then let him fall to the ground.

"Uuughhhh," Colin moaned miserably. "Fuck me." His balls were absolutely killing him.

"Yes!" Bella exclaimed. "Score!" She looked down at Colin, who was crouching on the floor and making funny moaning sounds. "Yeah, using an uppercut is a great technique in this game," she said. "Because then you get the balls from below, and they're really sensitive from underneath. Well, I guess I should say it's a great technique against a boy-- I don't think it would have made much of a difference if I was facing another girl." Bella laughed. "Okay, your turn again!"

The last thing Colin wanted to do was keep playing this game, but it seemed like it wasn't worth arguing at this point. He forced himself to his feet, caught his breath, and then punched hard into Bella's crotch, using a bit more of an uppercut this time.

"Mmm!" Bella hummed, biting her lip and opening her eyes wide. "Woo, okay." Her face became a little flush, and Colin got the sense that she had actually enjoyed that one. "Hoo, okay, that one just kind of got me in sort of a nice spot," she said, absentmindedly touching herself between the legs, as Colin watched with his mouth partly open. But Bella quickly collected herself.

"Okay, my turn again." She knelt down like she had before, looking at Colin's crotch appraisingly. "Spread your legs a little more," she said. Though he didn't want to, Colin obliged, but then Bella changed her mind. "No, actually, close your legs all the way, so that you're standing up straight with your legs together." He did what she said. She reached out and grasped his package, pulling it out and forward so that it rested on top of his closed legs, protruding almost cartoonishly from his body. "Perfect!" she said. "This is going to be a great shot."

She reared back and slammed her fist up into Colin's private parts like punching them was a carnival game and she was trying to win the top prize.

"Oohhhhh," Colin groaned, collapsing into a fetal position, his whole body trembling with the agony shooting out from his nuts. It was amazing how good Bella was at hitting him there; she never missed with a glancing blow. Every punch, kick, or slap landed with devastating accuracy, causing one explosion of pain after another deep in his tender balls.

"Yes, got you again!" Bella cried, as if it had been in doubt. "Ladies and gentleman, you are witnessing an absolutely dominating performance," she intoned in a fake announcer's voice, addressing an imaginary audience. "On one side, Bella is taking his crotch punches like they hardly even phase her; but on the other side, Colin is completely folding in the face of her punches to the balls. It doesn't seem like he's long for this match!"

"Ughh, you've got that right," Colin said miserably from the floor.

"Oh come on, don't be a sore loser; I'm beating you fair and square," Bella said.

"Yeah, except you don't have to deal with what it feels like to get punched in the nuts," Colin said.

Bella shrugged. "Well, I guess I'm well-suited for this particular sport. All right come on, one more round; let's see if I can score a KO."

Trying to get it over with quickly, Colin didn't bother getting up; he punched up into her crotch from his knees as she stood over him. He tried to punch as hard as he could, but a lot of his strength had been zapped. Bella hardly even flinched. "Mm, yum," she said, licking her lips, after his fist hit her between the legs. "Okay, my turn." She also didn't waste any time. She gently pushed Colin over so that he was on his hands and knees, and then, leaning over him, punched hard and fast between his legs from behind, her fist smashing into the very vulnerable pouch in his underwear, suspended beneath his butt.

"Ahhhhhh!" Colin cried in pain and surprise, folding back over his midsection; he hadn't seen that one coming and hadn't been prepared. "Oohhhh, fuck, ughh, oh my God," he mumbled. "Fuck. That one hurt worse than the others ones."

"Wooo! Ladies and gentleman, she scores a KO!" Bella said, assuming the announcer voice again. "She lands a devastating punch straight to the testicles, and she is the crotch-punching champion! The crowd goes wild."

"Congrats," Colin muttered weakly from the floor.

"Thanks." Bella said. "You didn't put up much of a fight, but I guess it must be tough when you're getting slammed in the nads over and over."

"Very true," Colin said.

"Okay, rest up till your boy parts feel all right again, and then I know what I want to do next," Bella said.

They went back to doing nothing. A long time went by-- it felt like hours-- and Colin was optimistically thinking that maybe Bella had forgotten about whatever she had in mind, and they were just going to hang out normally for the rest of the day. Enough time passed that once again the unpleasant antics of earlier started to feel like some strange memory.

But then Bella turned to him. "Okay, ready?" she said. "I know what that punching match made me want to do-- let's do some sparring!"

They both went to a kickboxing gym, and while neither of them was particularly serious about the sport, they'd done some casual sparring at home before, so the request wasn't as peculiar as her earlier ideas. Still, he felt wary.

"Okay, I'm down to spar," Colin said. "But on one condition: you can't kick me... you know."

Bella looked at him with exaggerated affected innocence, like she had no idea what he was talking about. "I can't kick you?" she asked. "How are we going to kick box if I can't kick?"

"Come on, you know what I mean. You can't kick me you know where."

"Sorry Colin, you'll have to be more specific," Bella said sweetly.

"Oh my God, fine," Colin said. "I'm down to spar, but only if you don't kick me in the balls."

Bella thought about it for a moment. "Okay," she said.

"And no loopholes," Colin said. "You can't punch them or slap them or grab my scrotum and twist, or reach into my underwear and crush them in your fingers, and then say 'oh, what did I do wrong, you only said I couldn't kick you there.' No funny business-- crotch is totally off limits."

"Okay, I agree," Bella said.

"I mean it Bella, I'm really serious. Do you promise?"

"Yes, I promise."

"Say the whole thing."

Bella smiled. "I promise not to kick you in the balls, or punch or slap your balls, or twist your scrotum, or reach into your underwear and squeeze your testicles until you cry. I promise we'll just do normal kick-boxing, and I won't in any way incorporate the fact that it's very funny to hit you in the nuts, and would also make it very easy for me to win."

Colin looked at her. "You pinky promise?" he asked, holding out his little finger.

"I pinky promise," Bella repeated, wrapping her finger around his with her hand over her heart.

Colin nodded, satisfied-- that seemed pretty foolproof. "Okay," he said. "Let's do it."

They moved the coffee table out of the way so that there was a big open space in the middle of the room.

"Okay, count down from three," Bella said.

Colin assumed a loose, limber fighting stance, his feet slightly apart, arms held lightly in front of his chest, rocking his weight from foot to foot. "Three, two, one-- Go!"

Without hesitation, Bella took one step forward and kicked him right in the balls, very hard.

Colin bent at the waist and froze, a look of total shock on his face; he had truly not expected it at all, and that had made Bella's kick all the more devastating. He fell to his knees and buried his face in the carpet, the muscles in his legs quivering like jelly.

"Ooooohhhhhhh," he groaned miserably, his voice coming out low and awful sounding. He beat his palm against the floor in frustration. "Fuuuck."

Bella was doubled over with laughter, laughing so hard she was snorting. "Oh my GOD," she said. "That was the funniest thing ever."

"Ughhhhhhh," Colin groaned into the carpet, trying not to sob. He lifted his face, which was red, the muscles in his neck tense and straining. He looked at Bella in dismay. "You *promised* you wouldn't do that," he said indignantly, his voice weak and choked-sounding.

Bella had to catch her breath from laughing. "Yeah, I lied," she said. "I just said I wouldn't do it, but I did it anyway." This explanation made her start laughing all over again. "Oh my God, that was good," she said, wiping a tear away from her eye. "You should wear a cup. A pinky promise isn't gonna protect your balls any better than that thin layer of cotton you're wearing."

Colin was in excruciating pain. On top of that, he felt immensely betrayed and humiliated. 'Ohh, Bella, that was so mean," he said, his voice breaking towards the end of the sentence.

"Haha, yeah, it was!" Bella agreed. "I mean, I guess it's always kind of mean to kick a boy in the sack, but that for sure took it to another level!" She took a long slow breath, trying to control her laughter. "You fell for it so badly. I was just like, 'sure, I promise I won't do that,' and then BAM! Kicked you right in the testicles. You should have seen the look on your face!"

"I really wish you hadn't done that," Colin said, his voice still strained and weak.

"Oh my God, so dramatic," Bella said, rolling her eyes. "You're just mad 'cause I rang your bells. You don't have to take it so seriously."

Colin unfolded his agonized body and gingerly lay flat on his back, pressing his palms into his eyes. Bella grinned. "All right, well let's see what we're working with here," she said.

She quickly grabbed Colin's boxer briefs and yanked them off. He gasped and took his hands off his eyes, but he was too scared to move.

"Whoa, Colin," Bella said appreciatively. "You're a pretty big boy down here." She casually took his naked package in her hand; his heart rate almost doubled. "Oooo, and so nicely shaved," she said. "Is that how your girlfriend likes it?"

"Um," Colin said nervously. "You know I don't have a girlfriend."

"Who's it for then?" Bella asked.

"No one-- it's for no reason."

Bella narrowed her eyes at him. "Why do I feel like that's a lie?" she asked. "Ooo, this is like an interrogation-- we have to get the information out of the suspect by any means necessary. Tell the truth!" She slapped his naked ballsack with her hand.

"Ahh!" Colin yelped; his balls were still so tender, he really couldn't risk having them slapped more. "Okay, fine! I do it for me. It uh, it feels better to have everything shaved when I'm, uh, you know... jerking off."

Bella's eyes widened. "Oh my God!" she said. "That's so adorable; and embarrassing!" She felt his package in her hand absentmindedly. "Do you jerk off a lot?" she asked.

"Uh, no," he said. She slapped his nuts again. "Ahh! I mean, I don't know, I guess kind of a lot."

"Hmm," Bella said. She looked into his eyes. "Do you ever think about me when you jerk off?"

Colin froze. He did not want to answer that question truthfully. "No, never." he said.

Bella slapped his balls incredibly hard. "Are you sure?" she said with a smile.

"Um, yes?" He struggled to speak through the pain.

She slapped his nads again, just as hard.

"Really!" he said, coughing and whimpering.

She made a fist and punched him in the place he most desperately didn't want to be punched. He howled and curled his legs up in the air, but she was holding him down so that he couldn't actually protect his most vulnerable part. Then she slapped his sack again, and again, hitting mercilessly hard each time.

"Okay!" he shrieked; he realized he needed to give in before he couldn't speak and had no way to stop her from slapping his nads. "Yes, I think about you when I masturbate. I think about you kind of a lot."

"Colin!" she said, and slapped his balls four or five times in quick succession, causing him to squirm like a fish out of water. "That's so naughty!" But he could tell she wasn't serious, she just wanted to torment him. "How about I give you something to *really* think about?" she said.

As he lay on his back, naked from the waste down, she took one testicle in each hand, between her thumb and first two fingers; even without her applying much pressure, he could feel what a powerful grip it gave her. She looked into his eyes, biting her tongue and giggling like she was about to play an ingenious prank on him. He gulped hard as he felt her adjust her grip and apply some test pressure to his unthinkably vulnerable testicles.

"Ready?" Bella asked.
