As the three knockouts cooled off with some more beverages, the sisters were still happily surprised by Naomi's bold, flirtatious interaction with Scotty's dick. Naomi was usually very strict with her diet and the alcohol was clearly affecting her the most. Still, they prepared fresh drinks and clinked their coolers together with a "Cheers to Breaking Balls!" as Scotty withered in pain behind them.

McKayla saw the light flashing on her phone, and was excited to see Krystal and Layla had replied to their message and photo of Scotty's swollen plums.

Krystal, the small, Asian flyer from their Cheer Squad had replied with, "OMG! OMG! OMG! Is that Scotty's Balls!?!?! 🙀🙀🙀 Girl you are Brutal! Destroying your own boyfriend?!" followed shortly by, "Need some help?? 😁"

Layla, the taller, powerful, black girl on the Squad had responded with, "NIIICCCEEE!!!!!" and then, "Wait you're letting Naomi help you! Fuck that, I'm your Ball Smashing go to girl! 😈😝😈"

The trio chuckled as they reviewed the messages and consumed their drinks. Alexia remembered when Layla had pulverized Chuck with Knees and Butt Bombs before launching Krystal into the air to double stomp him into retirement. "Should we invite them over?" McKayla asked.

Naomi looked back at the boy next door still laying face down on the floor, cradling his nuts. "You can, but I'm not sure your man will still have balls by the time they get here!"

Alexia clinked her glass with Naomi's, she embraced her and squished her exposed tits up against her girlfriend. "Fucking right! I seriously think his balls were about to explode in our hands there McKayla. You're lucky my woman stopped us or your little fuck toy would probably be in an ambulance right now." The threesome laughed at the thought of it.

McKayla started typing a message to the girls on her phone, "You're welcome to join! Momma's out for the night, and we're having a Nut Hitting Party! The more the merrier!".

As McKayla sent the text, she saw the notification from the video call Ms. Taylor had accidentally initiated before. McKayla remembered the strange looking surroundings from the call and decided to check in on her. She texted "Hey, where are you? Did you mean to call?"

She set her phone down, and looked back to her sister and Naomi who were once again making out and groping one another. "Round #4 Ladies!" she declared. 

*   *   *

Scotty's waves of agony had finally eased to a more tolerable level of pain that allowed him to pull himself up from the floor. As he rose on wobbly legs he watched the three vixens compose themselves for the next challenge. Naomi and Alexia were fairly intoxicated. Alexia was now almost completely naked with only her pink, micro thong covering her tight little pussy. The powerful goddess Naomi was still fully clothed, even though her big fake titties were bursting from the bottom of her cut off shirt. McKayla, his girlfriend, was showcasing a stunning, metallic, golden bikini which contained the little folded up pieces of paper that indicated the next challenge. The women finished up on their phones, as Alexia hit the next song on her playlist "Gimme More - Britney Spears".

The song started with the iconic "It's Britney Bitch!" and the trio roared into action, with his girlfriend leading the charge. McKayla strutted toward him to the beat of the music, her hottest escalated to a new level. She reached behind her back and pulled the loose string on her bikini top to undo it. She peeled the metallic gold fabric down displaying her amazing breasts. Both sisters were down to their tiny, thong bottoms, and despite the agony, he loved where this was going. Laying inside the cup of her bra was a single remaining piece of paper, she held the bra out so her boyfriend could do the honours.

He was barely able to tear his eyes off her naked boobs dancing before him, and focus on the words on the paper. He read them out loud to the ladies as "Gimme More" blasted throughout the basement:

"CHALLENGE:

Take ~50~ Knees!

REWARD:

Hand job"

A smile broke out on his face as he read the words "Hand job", but before he could look back at McKayla, she grabbed his shoulders and Thrust her Knee Hard into his Naked Balls.

SPLAT!

Scotty folded over forward, his face landing between her soft welcoming tits. For a moment, the pain was almost worth it, and then she cracked him three more times!

THUD! SMACK! CRUNCH!

Scotty's legs snapped together, his legs shook and he fell to his knees cradling his plums as the three ball breaking women shared high fives and danced to the music. It really was a party. The three sang along to the lyrics being sure to tease their kick dummy as they danced.

Alexia strutted over to him as she belted the lyrics "Just wanna go that extra mile for you..." she pulled him back to a standing position, turned her back to him, and pressed her firm buns back into his exposed groin. Scotty moaned in pleasure as only her thin, pink thong covered her incredible ass as she gyrated it up against his hardening cock. Scotty knew it would end badly, but he enjoyed the feeling of her bare cheeks rubbing against his manhood up until the point where she turned back and kneed him hard with her kneecap.

CRACK!

Again, Scotty folded over, only this time it was Alexia's bare tits that caught his face. She cupped her hands behind his head, forcing him to stay smothered, but also keeping him stationed in front of her as she rapidly drove knees repeatedly into his naked nuts.

SMACK! CRACK! CRUNCH! CRUNCH! SQUASH!

Scotty lost count as the number entered double digits and his precious globes were pulverized by her repeated knees. "My nuts, my nuts, please stop!"

The booze was hitting Alexia, and her excitement and emotions were getting away from her. Part of her was weirdly jealous that Naomi had brought Scotty so much pleasure with her short blow job, and yet another part of her wanted to win one of these challenges! The frustration needed to be released, and Scotty's balls were perfect for the job.

Alexia smashed her knees even harder into him, driving them through the target the way she'd learned in Naomi's self defence class. He tried to pull away, but she brutally grabbed him by the balls, pulling him back towards her to receive another round of knees.

CRACK! SMASH! CRUNCH! THUMP! THWACK!

Alexia caught eye's with Naomi as she came up from behind Scotty with a mischievous grin. Alexia knew she had evil intentions but she wasn't sure what they were. Alexia gave Scotty a brutal final knee 

CCRRUUNNCCHH!!!! 

As he tried to reach for his broken nuts Alexia grabbed his hands and held them away, leaving an opening for Naomi. The Amazon Goddess was smiling from ear to ear as she balled her fingers into a tight fit, dropped to one knee and delivered a powerful, low blow style uppercut from behind into his unprotected nuts. Her muscular arm shot up between his legs lifting him into the air as her fist exploded through his testicles. He howled like a wounded animal before collapsing to the carpet. Naomi barely skipped a beat in the music as she slipped off her booty shorts to the beat of the song, and dropping her buns of steel onto their fallen toy. "Gimme Gimme More!" Alexia and McKayla joined her, grinding him with their own thong covered asses, and stomping on him to the beat of the song.

The trio continued to dance over their broken slave in a sexy mix of sensual moves and humiliation as Britney Spears blared through the speaker. Scotty could feel them bouncing and grinding their asses and feet into him as they laughed and mocked his pain. Scotty looked up just in time to see Naomi peeling off her crop top and showcasing her incredibly massive, and rock hard breasts. After a short break they pulled him back up to his knees so McKayla could tease him with her butt. She twerked in front of him, occasionally smashing her buns into his face. He was slowly getting his energy (and boner) back, when Alexia joined her sisters side and Scotty was blessed with two incredible asses twerking inches from his face. He couldn't help but hold onto their legs and motor boat his face as they smothered their firm booties into his face. Suddenly he felt Naomi's butt cheeks join in as she pressed her rock hard glutes into the back of his head, effectively sandwiching his head between 3 amazing asses. Scotty was in heaven, but of course that couldn't last.

As he kneeled on the floor Scotty's vision was monopolized by the Taylor sisters, perfect, thong covered asses grinding into his face, to the rhythm of "Gimme Gimme More". As if that weren't enough pleasure for him, suddenly he felt the bottoms of their smooth feet begin to gently stroke his hard cock. Their toes were skillfully cupping his dangling balls, and groping his cock, Scotty was ready to erupt when the gentle caressing got a bit rougher. The sisters reached between their legs to secure Scotty's wrists, and began slapping his balls with the soles of their feet as they kicked, donkey-style back into his crotch. With his head squashed between 3 firm asses, and his arms being held by the sisters, all he could do was kneel there and try to survive the pain. The trio sang along with the lyric's kicking him with every word;

"Gimme, Gimme, More!"

THWACK! SMACK! CRUNCH!

"Gimme More, Gimme Gimme More!"

SQU-ASH!! CRU-NCH!! THUMP!!

Alexia and McKayla pressed back, stepping down and crushing his balls beneath their feet. Scotty's cries went unnoticed as his naked testicles were smacked, kicked and crushed.

Just when he thought he couldn't take anymore the sisters finally stopped. They turned to face him and relocated Scotty's hands to cup their asses and once again their sexy feet provided pleasure. The two drop dead blondes stroked his package with the insteps of their feet, and their freshly pedicured toes. They affectionately ran their fingers through his hair, looking down at him seductively. McKayla pulled his head back as she whispered towards his ear "I wanna fuck you Big Boy!"

His dick spasmed in joy.

Alexia reached down, gently stroking his massive cock she whispered, "WE wanna Fuck You!"

His dick seemed to be stretching beyond its usual maximum length, "reaching" toward the ceiling.

Naomi removed her booty from the back of his head, turned around and instead pressed her massive tits up against the back of his head as she sensually reached around him to massage his manhood. "We ALL wanna Fuck You!" Naomi added as she took hold of his rock hard cock (secretly getting it out of the way for the sisters).

Scotty was in heaven. He could feel Naomi's firm tits, pushing up against the back of his head, one of her hard nipples tickling his ear. He turned to try and capture it in his mouth. When her long fingers wrapped around his dick it began to convulse and prepare for a long over due eruption, Scotty's eyes rolled back in his head.

Naomi continued to whisper, "We ALL wanna Fuck You..." she shared an evil grin with the sisters before continuing, "Fuck You UP!" It was at this moment that the sisters retracted their insteps from his balls, only to gather momentum and kick them hard into his exposed genitals with Maximum Force.

SMAAACCCK!!!

The two kicks connected precisely at the same time, completely CRUSHING his Balls in the process!

Scotty's orgasm was cancelled, as the double kick sent his balls and hips flying backwards as his upper body launched forward. His arms instinctively tried to protect himself, unfortunately McKayla and Alexia each held them firmly. He now found himself hunched over forward with his backside pointing towards the Amazon Goddess. Like the pro-ballbreaker she was quickly becoming, Naomi grabbed Scotty by the balls forcing him to stand. "Open your legs!" she commanded.

Scotty just howled in pain. He couldn't comply, his nuts had been destroyed by the Tag Team Kick.

Naomi squeezed harder, "Open your legs or I'll Rip your Fucking Nuts Off!"

The sisters pussies became wet at the thought of Ruptured Balls.

In agony, Scotty reluctantly opened his legs, terrified he was about to lose his nuts. He was completely compromised, bent over, legs spread, and his hard dick was still waving around beneath him quivering like it was still trying to ejaculate but his broken testicles weren't cooperating.

Naomi braced herself on Scotty's hips as she measured her powerful thigh into his exposed package. Her kneecap aimed right at the underside of his hard dick, such that her massive thigh could crush his precious plums. She brought her leg back to the floor to build up maximum momentum and then with all her might she SLAMMED her Knee HARD into his package. Her kneecap Squashed his massive rod, and her firm thigh CRUSHED both of his orbs, flattening them into his body. Scotty was lifted a couple inches off his feet, as the sisters held his arms securely.

Naomi retracted her powerful leg, planting it back to the floor only to drive it forward again. As Scotty's feet barely returned to the floor his manhood was once again SMASHED by her knee and thigh driving through him, and pushing him back up into the air.

SMASH!!

THWACK!!

The Amazon Goddess didn't stop. She repeatedly drove her knee into his balls, driving them through his body. Scotty was riding her leg like it was a sadistic bucking bronco.

CRUSH!! SPLAT!! CRUNCH!!

The sisters laughed uncontrollably as Scotty looked like a rag doll, bouncing up and down on the knee of their tall, athletic friend.Scotty's face was deep red as he begged them to let him go. "Please! No more! My nuts! This hurts so much!"

McKayla teased, "I don't know Scotty, I don't think that was 50 knees yet?"

Alexia agreed, "Ya, I think maybe 10 - 20 to go?!"

CRUNCH!! SQUASH!! SMACK!! THUMP!! 

Naomi continued kneeing Scotty into the air as his arms were completely restrained by the sisters. Finally she finished with her most powerful knee yet, driving it with Maximum Force through his package

CRRUUNNCCHH!!

She continued driving her knee (with Scotty on it) up towards the ceiling, lifting him almost a foot off the floor as she ground into him for several seconds before finally letting his feet drop back to the carpet. But the three vixens still weren't done...Scotty's body was overwhelmed with pain and his vision was blurred as he slipped in and out of consciousness. Other than the pain in his nuts he could barely feel the rest of his body, and the dominant Naomi was easily able to take control of his limp body. She locked him into a full nelson, locking his arms above his head as her hard breasts and nipples poked into his bare back.

McKayla and Alexia stood before him, their pussies wet with anticipation of busting the helpless Scotty. The trio was overcome with a feeling of Power and Dominance. They knew that the future of Scotty's manhood was literally up to them, they could let him keep them, or perhaps they could decide today would be a good time for his CASTRATION! Each sister braced their hands on each of his shoulders and prepared to knee him without mercy.

With each strike Alexia and McKayla would drive their knees as hard as they could into his swollen balls. His softball sized nuts were now turning a shade of purple as the sisters alternated turns. With each impact they were moaning in joy and pleasure as their pussies got wetter.

"Yes!" screamed Alexis;

SMACK!!

"Oh ya baby!" screamed McKayla.

CRUNCH!!

"Fuck yes!"

SQUASH!!

"Bust for us!"

THUMP!!

Scotty was out on his feet, but his body was still unconsciously yelping and crying with each strike, which of course only made it hotter for the sadistic trio.

The sisters pummelled him faster and faster with knees, their tempo eventually changing from alternating strikes to simultaneous double knees at the same time. Alexia and McKayla immediately found by driving their hard kneecaps, into each of his balls (one knee per a testicle) at the same time really seemed to cause maximum pain as Scotty's howls reached a higher pitch. They could feel his swollen nads being squashed by the impact.

Despite their hardest, double knees, and perfect timing, it was not enough to rupture him. As the sisters gave him one final double knee out of frustration, Naomi joined in by driving her powerful knee up from behind, Smashing hard into the base of his nuts as they bulged out to their limits below the pressure of the sisters knees.

SQQUUAASSSHHH!!!!

Scottys body collapsed, convulsing on the floor as Naomi stepped on him to get to her girlfriend. She lifted her off the ground and Alexia wrapped her legs around her waist, as Naomi pinned her up against the wall in a passionate kiss. McKayla couldn't help but rub her own pussy as she watched her broken man quivering on the carpet.

As McKayla's fingers slipped down the front of her thong bikini she felt a folded up piece of paper, the final Challenge. "Sorry to interrupt ladies, but we still have one final round!"

Naomi and Alexia looked back excited for more as McKayla read the last paper:

"CHALLENGE:

Trample and Stomp Scotty's Nuts until they POP*~!~*

REWARD:

Threesome!"
