Kat's Anniversary Challenge

All characters in this story are at least 18 years old.

Evan woke up from a dull pain radiating from his testicles. The next thing he became aware of, was the nude body of his dream girl tightly pressed against his. He was on his side, his right arm serving as a pillow for the smaller Kat who was on her back. The position left his left hand free to feel and explore the wonderful body of the sleeping beauty, whenever he wanted - currently cupping her perfect, firm right tit.

A wave of happiness greeted him, like nearly every morning. Even after one year, Evan still couldn't believe that he had scored this perfectly naughty and pretty girl. The early summer heat made them sleep fully nude and without blankets, which intensified the wonderful sensation. Barely seconds after he woke up, Evan was rock hard.

His eyes and left hand wandered down the cutie's body to address the continuous discomfort in his balls. Kat had her left knee pulled up to the side in between his legs, trapping his nuts in between her thigh and his pelvis. Evan slowly moved his hand along the inside of her soft thigh, before trying to push her knee down a bit to give his testicles some space.

Instantly, Kat increased the upward pressure of her knee and prevented his attempts. Evan closely looked at Kat's pretty face that was right in front of his. The cute Asian was totally relaxed, her eyes shut. Even after one year, Evan still hadn't figured out if she was only pretending to sleep when she pulled up her knee into his groin, or if she actually did it subconsciously while deeply asleep. It happened so regularly, both would have actually been immensely hot.

Very slowly and softly, Evan circled his fingers back up the inside of her thigh. As her knee was pulled up to nearly 90 degrees, her shaven vagina was wide open. The young guy felt his cock twitching desperately, when his fingers reached the end of her thigh and touched her amazingly soft pussy lip. A soft moan escaped Kat's mouth when his hand cupped her smooth crotch and he pushed his middle finger against her clit. The damp warmth welcoming the tip of his finger was so inviting that Evan nearly came, bare any stimulation of his pulsing cock.

When Evan began rubbing Kat's clit with two fingers, the seemingly unconscious girl suddenly pulled away her knee from his groin and finally released his aching nuts from the continuous pressure, closing her legs from the uninvited stimulation with a cute squeak. The lad had to bring up all his willpower not to jump on top of his girlfriend and wake her up by thrusting his cock into her. She was going to wake up horny anyway, he thought, given the heat and dampness from her pussy that caressed the palm of his hand.

Ignoring the raging arousal in his private parts, Evan forced himself to get up and look for something to wear. They had visited his parents over the long weekend, who had left for a vacation the previous night. Although no one else was in the house, and Evan and Kat almost always stayed naked at their own places, it felt weird for Evan to walk around naked in his parents' house.

Since the clothes that he had brought were currently in the laundry, all he found in his past kid's room was some men's slips that he had luckily exchanged for boxers at least ten years ago. He knew exactly, why, when he struggled to get his boner into the tight fabric. It didn't matter, he figured, as he only had to get breakfast before taking them off to do whatever Kat had in mind this morning.

When Evan returned to the room with a tablet of waffles, fruits and orange juice, his cock was still fighting the thin, white fabric for every bit of space. It was their first anniversary, which meant that they'd probably spend a good part of this day making out, fucking and cuddling, over and over. The simple prospect had a similar effect on him, as he imagined a couple of Viagra pills would have. When Evan pushed open the door with his foot, the nude Kat sat on the center of the bed and greeted him with a wonderful, warm smile.

"Happy anniversary!", both said in unison, before Kat's eyes darted down and she broke out in laughter. Evan approached the foot end of the bed while balancing the tablet with two full glasses of orange juice. Kat was still laughing hysterically, while obviously staring at his groin.

"What the fuck is this? Tighty whities?!", she blurted out in a mocking tone. In one swift motion, the smaller, naked girl pushed herself forward and sat at the edge of the bed right in between her boyfriend's opened legs, when he was just about to kneel on the same spot to approach her. The standing Evan was instantly intimidated by the ballbuster girl sitting right in front of his uncomfortably trapped nuts.

To get his hands free, he quickly tried to place the tablet on the mattress next to her. But Kat's hand was already at its bottom and began pushing up. The tablet nearly tilted and spilled all the juice, and all Evan could do was bring it up over his head until it was out of Kat's reach.

"Up! Up! Yes, there you go.", Kat purred while Evan straightened his back and lifted his arms up with the food. In the next moment, the nude cutie curiously cupped his balls and cock with both hands. The briefs were a size or two too small for Evan by today, and left his junk beautifully at display for the horny girl.

"This is soo cute!", Kat continued mocking him with her distinct giggle. Suddenly, she grabbed the elastic waistband at both sides of Evan's hip and mercilessly pulled it up to further stretch the discomforting fabric over his testicles. Evan groaned; his balls felt as if they were about to bust through the cotton. Kat's face was almost at one level with his genitals and she watched the effect of her front-side weggy with obvious delight.

"Jeez, isn't that uncomfortable?", she asked, as if she was on to something.

"Ughhh... ehhh. Yeah?", Evan pressed out. His raging boner suffered from the restriction nearly as much as his compressed testicles. He would give his left nut for the pretty girl to release his junk and give him head right now. Probably, he wouldn't last more than ten seconds. But he was afraid that she had only just started the mocking, teasing and torture.

"Does a kick in the balls hurt more, when you're wearing one of these? It should be way easier to get them good, right?", Kat asked, her pretty dark eyes suddenly locking up into his. Evan had to think for a moment, which was quite hard right now. Actually, he wasn't even sure if he had ever gotten a kick in the balls when he was wearing tighty whities.

"I don't kno..ouuggghhh", he groaned when Kat's fist shot up in between his legs and smashed into the tight package that contained his vulnerable nuts.

"Now?", Kat smiled sweetly."Yeah... it does for sure.", Evan gave her the satisfaction she was waiting for. With nowhere to escape, his balls had indeed painfully absorbed the full blow. If he hadn't been with the notorious ballbuster for a whole year, he would be rolling around on the carpet in front of her feet now. Unfortunately, his tolerance wasn't really one to pain. It was much more one of body control despite the pain.

"I expect you to bring home a couple of these, when we get back.", Kat added in a much more strict, dominant tone. The imagination of walking around in these ridiculous undies only to allow his girl to bust his balls more effectively was insanely hot. Evan started another attempt to put down the tablet and get to fuck his girlfriend, but Kat's left hand was there again to stop him. When he lifted the tablet and tried to take a step back, her right hand shot up and grabbed his balls, painfully squeezing and pulling him back into position. There was simply nothing, he could do.

"Thanks for the breakfast, by the way. But I think I may have something else this morning.", Kat said in a breathy, seductive voice and let her eyes wander back down to his manhood. Her right hand still firmly wrapped around the tight package containing his balls, she suddenly pulled down the waistband of his briefs at the front with her left. Gratefully, Evan's massive, hard cock jumped out right in front of her face. Evan shivered in a mix of excitement and agony, when Kat slowly licked her lips, opened her mouth and pulled Evan closer to her face by his balls. Just when he closed his eyes and waited for the wonderful sensation to set in, Kat halted.

"How many girls have you fucked here, sweetie?", Evan heard her say, while soft gushes of warm air caressed the tip of his twitching cock. When he hesitated, the pressure on his nuts rapidly increased.

"Uhhh... ehh... four. And you.", he quickly moaned submissively. "And how many of these girls have kicked you in the balls at some point?"

"One... And you.", Evan answered, remembering the light, playful ballbusting with his latest ex girlfriend Ann.

"Just one... humm.", Kat said, her mouth sill less than an inch in front of the tip of Evan's cock that was desperately oozing pre-cum. "Would you be up for a challenge today?" Evan opened his eyes and looked right into hers, malicious and expecting. Sitting naked at the edge of the bed right in front of him, she was beautiful beyond imagination with her naughty smile. Below her face, Evan got a perfect view from above on her round boobs, her flat stomach and her hypnotizing, smooth female crotch, opened for him as she was pressing her knees outwards against the insides of his, keeping him fully open.

"Ehhm... suure. But could you please...", Evan began begging for a release, but the sudden ache inflicted by her hand around his balls got him to shut up.

"Actually, no! It has been quite a while since your last challenge. We don't want you to take me for granted, right?", Kat teased him, before very sensually licking the downside of his cock with the tip of her tongue. Evan moaned and shivered in arousal. He clearly remembered the series of challenges that he had to go through to win this amazing girl. The paintball shots into his balls, the countless kicks, squeezes, fights, games, endurance tests. It had been hot, but incredibly hard to go through. After all, the reward was totally worth it. Evan complied and nodded slowly.

"Awsome!", Kat cheered joyfully. "How many of your ex-girlfriends are still in town?" The question startled Evan.

"Not sure. At least two, maybe three.", he answered, suspiciously.

"Perfect!", she exclaimed, before continuing her explanation. "I want you to visit them, and say the following sentence: 'Dear - say her name -, not a single day passes that I don't think about you. I have mistreated, wronged, disrespected and never deserved you. But I can't help it, because I am a man and slave of my testicles. To make amends, I wish to offer you these balls, to do with them as you see fit for me and my past behavior."

Evan felt his chin dropping to his chest. While Ann and him had parted on good terms, this was clearly not the case for some his other exes. The imagination of offering his testicles to them was simply scary. And the way he was supposed to do it was even worse.

"But... why?" Evan was speechless.

"I believe that ex-girlfriends should be busting balls more often.", Kat calmly explained to Evan's cock, her soft lips making it hard for him to focus on anything beyond his throbbing dick in front of them and his nuts in her tight grip. "You know, if a girl kicks a stranger in the balls, there are all these lines that she has to cross. In order to hurt him, she has to imagine, target and touch his genitals. As a girlfriend, these red lines are dissolved. A girl constantly sees, touches and is aware of her boyfriend's balls next to her. But they are her own precious toy, and a harsh kick could always affect the... you know... sexual performance of her man. But an ex-girlfriend is the perfect mix of both: She knows your balls. She has watched and felt them slap against her clit in doggie style countless times. She has grabbed them, sucked them. But suddenly they are not hers anymore. Suddenly, they are just the vulnerable balls of that fucking guy who has mistreated her. I don't care if you actually did. I just wanna see your exes make that judgement and have their way with your balls. Ask them if you can film it. I really wanna see this."

Evan stared down at the nude cutie in disbelief. Kat's monologue on women's relationships to the balls that they want to bust was equally shocking and plausible.

"Isn't this... cheating, somehow?", Evan asked, confused. If he asked Ann to bust his balls, there was no way that it wouldn't lead to nudity, teasing, maybe even more.

"Oh you can do everything, but if you come or put your dick into some pussy, you can consider me your next ex to bust you. And believe me, the second these balls are not mine anymore, I will kick them so hard that you won't even be able to remember if you had been born a boy or girl."

Evan swallowed. Kat's voice always had this sexy, deeper undertone when she was threatening his balls. But he couldn't allow himself not to take her dead seriously.

"Can you at least let me cum before?", Evan carefully asked one more time, but Kat just gave his trapped balls a rough slap before she let herself fall back on the bed, her legs still opened invitingly. Her shimmering black hair was spread out all around her head and made her look even more desirable.

"You can fuck me once you got these videos for me.", Kat said in a seductive voice, still flashing her pussy right at her boyfriend who was horny beyond imagination. Evan just had to go for at least one more attempt. He placed his left knee on the mattress right next to Kat's bare hip and quickly moved the tablet down to her other side. Kat's left foot shot up and was at the bottom of the tablet instantly. One of the glasses finally tilted from the impact and covered Evan in ice cold orange juice, making him gasp. His naughty girlfriend was already laughing at him, when her right knee shot up into his tight, exposed package an instant later.

Despite his tolerance, the kick was cruel enough to floor him. Somehow, he managed to more or less safely place the tablet on the floor, before he rolled into a tight ball next to it. His mind alternated between the brutal emasculating agony radiating from his balls, Kat's feet that rested on him in a silent demonstration of female dominance, and the raging boner that refused to stop demanding attention. Evan accepted that the only way to fulfill his desires was to get Kat the videos of his ex-girlfriends busting his balls.

...

When Evan returned, he really wasn't sure if his testicles were going to be able to handle his ballbusting girlfriend for the rest of the night. He had encountered two of his ex-girlfriends and after some initial suspicion, both of them had agreed to "some" kicks in the balls in front of the camera. From Ann, he had expected it. But Mara, who had been his girlfriend before Ann and whom he had betrayed with Ann, simply busted him out of spite. Both visits had turned into some really intense sessions.

Kat had been absolutely right about the exes-and-balls situation. With Ann, it had been the usual sensual teasing and playful busting, but the ruthlessness of her kicks was far worse than when they had been dating. And Mara... she really had some anger issues and deeply buried revenge fantasies about Evan. The dangerous glister in her eyes when he repeated Kat's offering of his balls at her door had been very telling.

Evan limped into his bedroom, while Kat was in the shower. After connecting the TV and setting up his homemade ballbusting videos, he couldn't wait to escape the tight, ball-compressing underwear that Kat of course had insisted on. The color and swelling of his nuts was nearly concerning. When he finalized his testicle inspection, he pulled his shirt over his head.

Just in that moment, the door opened. Blinded and restricted by his shirt, Evan knew exactly what was about to happen. Since the very first date, it was a running gag in their relationship. Barely a second after the door was opened, Kat welcomed him with a rough kick in his unprotected balls. The audible slap of her bare foot against his bruised nut-sack was instantly followed by a brutal rush of agony. Three twats taking turns trashing these testicles took their toll. Evan got out of the shirt and sunk on the floor, overwhelmed by the ache in his private parts.

"Ouuhh, they feel swollen. I figure, you completed your challenge?", the nude and dripping wet Kat purred while stepping over Evan towards the bed. He tried to answer, but the pain of each additional kick seemed to multiply with all the previous ones he had received today. The lack of an answer satisfied his naughty girlfriend. "Then come and fuck me hard, babe."

Kat's voice dripped in seduction like her hair from the water. Evan fought down the waves of agony and pushed himself up in front of her demanding eyes. The girl slowly and gracefully knelt on the bed, facing him, before bending down and placing her elbows on the mattress, her tight butt pointing up and her legs opened.

The implications of her position made Evan quickly forget about the current state of his genitals. He had been so insanely horny since the moment that he had woken up. All the teasing and busting that he had endured on this day, was going to make this reward as rewarding as it possibly could be.

With a massive, throbbing boner over a pair of purple, swollen and constantly aching nuts, he jumped onto the bed and went down onto his knees behind his dream girl. As she was significantly smaller than him, he had to open his legs even more than her to get his groin on one level with hers.

The moment, he slipped his cock into her tight pussy and almost yelled from the delightful sensation, Evan felt Kat's hand reaching back between their legs to softly grab him by the balls. The initial pant inflicted by the sharp pain quickly turned into deep moans. As her butt was tightly pressed against his abdomen, there was no way to protect his tender testicles from the naughty bitch. All he could do was satisfying her and begging her to be gentle with his male weakness.

Without stopping the pounding in doggy-style, Evan grabbed the remote next to him and started the first video. Mara had insisted not to show her face on the camera, so only her feet and lower legs were visible in front of Evan who had had to strip to his ridiculous underwear and lock his fingers behind his head. With his legs spread widely, the Evan on TV received one brutal kick after the other. There was nothing sensual, or teasing, just an angry ex-girlfriend to welcomed the chance for every hurtful, humiliating blow she could dish out.

It was very clear that Kat loved what she saw. Her pussy was hot and dripping wet, and she began fondling Evan's balls with both hands, her tits pressed against the mattress and her neck arched back to fully enjoy her boyfriend's anniversary present. Every time, Evan on TV fell down to cup his balls and cope with the pain, real Evan got his testicles slapped and flicked around by Kat, impatiently waiting for TV Evan to get back up and receive the next kick.

Evan knew that the two videos would take over 15 minutes each and desperately tried to focus his mind on something that wasn't gonna make him shoot out his load. Before the first video was finished, Kat came very hard and almost made Evan come, too. Trembling, he tried to remain the bit of control that he had over his body, while the cute girl in front of him panted in heavenly delight.

When they got to the second video, Kat suddenly got back onto her hands and more carefully watched the scene. Ann had made Evan strip fully nude, tied his hands over his head where a punch meat or something more naughty could be attached and changed to a skimpy mistress outfit like nothing Evan had seen during their relationship. The busting was playful and sensual, and interrupted by teasing that had almost made him cum and loose his balls to Kat. But just like Mara, ex-girlfriend Ann was free of any of the affection and mercy that he had been used to.

While the busting in the video intensified, Kat began thrusting forward and back harder and harder. Every time, her butt slapped against him and his cock was fully inside of her, his swollen balls swung forward right against her clit. The couple panted in unison with every faint slap, Evan from the harsh sting in his violated, pounding nuts and Kat from the sensation of the swollen pair bouncing against the center of her bodily pleasure with every thrust.

When the skimpy blonde in the video picked up a baseball bat and teasingly circled it around the tip of TV Evan's hard cock, Kat started screaming in excitement and joy. Evan clearly remembered the torment that had come along with the following minutes of the clip. He found it both amazing and horrifying, how Kat seemed to enjoy his obviously sensual but incredibly painful interaction with his pretty ex. But Evan knew very well what his girlfriend would not hesitate to do to his testicles, had he disobeyed her initial rules.

Around the fourth or fifth hit with the baseball bat, Kat couldn't hold it and came, her body trembling from the sudden loss of control. Evan tried to hold out, but the rhythmic tensing of Kat's pussy pushed him over the edge. The wild mix of teasing, awkward meetings and intense ballbusting that he had been through over the course of the day resulted in the strangest, yet strongest orgasm he could remember.

When he fell onto the mattress next to Kat, she looked at him with a mix of disappointment and gratitude. In front of her, nude TV Evan had to endure another couple of brutal hits, with no chance to escape his laughing ex. When she was finally done with him, she turned to the camera and addressed Kat with a hand kiss. Evan couldn't even remember it, as occupied with the relentless agony in his testicles he had been at this point.

"Thanks for that little surprise, honey. And congratulations for wearing the pants in that relationship.", Ann laughed before switching off the camera. Kat turned back to Evan and dangerously narrowed her eyes while her hand wandered down and got a hand full of whatever was left in Evan's scrotum after this day.

"She is a sweet one. If you see her again, I'll break your balls.", she hissed, smiling unpredictably. Evan really wasn't sure, if she was joking. "Now take a nap and make it hard again. I want to watch this again!"
