TW; mention of ruptures, post-orgasm torture, intense busting.

The women all stretched, their lunch only recently finished, giving them the much needed energy for the workout that awaited them.

Limbering up, Ruby stretched her hamstrings, feeling the nice warm stretch down her long legs. Adorned In skimpy activewear, a pair of near see through bike shorts barely contained her juicy ass, a crop top like sports bra held her big breasts in tightly, every bob and move causing them to jiggle faintly.

She stood upright, stretching her hands to the sky to reveal a tight and toned midsection, butterflies tattooed across her ribs, her black hair tied into a high pony, her feet tucked nicely into all black Nikes, new ones she got for Christmas.

She and a bunch other ladies stepped forward, each scantily clad in very revealing gym wear, their instructors pink set almost transparent under the heavy gym lights.

“Okay girls, it’s Boxing Day. We’ve been training all year so this is our chance to put those hours to work!” The trainer said enthusiastically, a whistle and stop watch dangling around her neck, resting neatly between two large boobs, the cleavage immaculate.

The girls all nodded and made various noises of approval, beckoning the trainer to proceed. The instructors waved a hand in a “come on” motion to the unlit and dank side of the gymnasium, stepping from the darkness in a single file row was a group of naked men, their pasty white skin and uninspiring bodies stepping into the light. Small, pitiful cocks, some caged some not stepped up, standing across the way from each of the gym goers, their balls hanging loosely in big heavy ball sack, each a nice warm tone, freshly shaven.

“You’ll have 40 minutes on the clock. Your task? Beat these balls to a pulp. When you’ve done with your ball boy, call out and another will be sent over to you. If you’re tired, let one of the other more spry ladies sub in for you.” The instructor said, causing some of the ball boys to shudder with worry.

“At the 40 minute mark, any ball boys that are intact will be given the opportunity to cum, the rest will be taken to medical and fixed up. The ball boys today have been training for the better part of a year, so they should give you a run for your money but, they’re not perfect.” She said quickly sack tapping one of the ball boys closest to her, the man wincing but keeping on his feet.

“We’ve caged the more…excitable ones, although the uncaged ones may rise to the occasion, please avoid their dicks, slap the head if you need to, their pleasure isn’t mandatory.” The instructor said with gusto, giving another ball boy a flurry of hard flicks before moving down the line.

“With all that said, unless there are any questions we will begin!” The trainer said with finality.

The ladies all looked from one another, no questions, with smiles and eager hearts they stepped toward their shivering targets; Happy Boxing Day.

The gym came alive with the sounds of hands, feet, knees and elbows colliding with weak balls. Screams and hollering rang out only muffled by the sounds of unabashed laughter and mocking words.

Some ladies took it slow, dealing steady heavy kicks one after the other in a rigidly timed motion, their ball boys puffing and panting as the ladies bullied them with humiliating words.

Others took a more wild approach, throwing knees, kicks and punches at the sacks of their boys with reckless abandon their laughter filling the air.

Ruby however employed a mixture of different disciplines; snap kicks she had learnt earlier in the year a favourited move, her very first kick catching her ball boy squarely on the left testicle, knocking it against his pelvic bone. He cried out instantly; “MEDIC!”

A girl in all white scrubs with a nurse had ran out and dragged the sobbing and crying man away, instantly another man jogged up toward Ruby, spreading his legs and placing his hands behind his back.

One by one different boys across the gym fell, either due to accidental or purposeful rupture or simply due to being unable to continue.

Some of the girls, who were now dripping with sweat high fived, some gave encouraging ass smacks to one another before the next boy arrived. Ruby watched momentarily to see a pair of women team up on a boy, each taking turns kicking his dangling sack, his manhood destruction was at hand.

Ruby didn’t hide the fact ballbusting turned her on, some of the women here proclaimed it was just a sport or an outlet whereas a small yet vocal minority like Ruby saw it for what it was; orgasm fuel.

A good buster was hard to come by, but a good bustee, was even more difficult to procure. After the first 15 minutes many men had been sent to the infirmary, some to actual hospitals while some of the gym goers tapped out, walking toward the benches to grab a quick drink or orange slice.

Ruby however, didn’t falter. She was a beacon of sweat, her bike shorts soaked through from a mixture of sweat and pussy juice, her top 100% see through, revealing two pierced nipples that stood to attention, rock hard.

Her new ball boy, had taken a thrashing, seven full force kicks, two knees, and a hefty right hook and he still stood. Granted he was panting, puffing and groaning and it took about 2 minutes for him to raise from the floor, but he still endured. He, as far as Ruby could see, was the longest lasting ball boy of the day, perhaps she got a good one.

“What’s your name?” She asked as she launched a hard, visceral kick into his nutsack, the kick forcing him to all fours. He moaned and groaned on the ground, fondling his bright red balls. Through all the pain he grunted out the name;

“Damien.”

“Well Damien, I’m Ruby. You seem to have a sturdy set of nuts!” She said, walking behind him promptly, launching a sneak attack on the backside of his balls.

The kick made Damien howl, he fell to the floor like a limp sack of potatoes, clutching his manhood in a desperate attempt to protect them.

All around the pair, sounds of sneakers to skin slapping. Groans of pain and the shrills of exhilaration. Some moans could be heard but were quickly stifled. Ruby on the other hand didn’t care, she berated Damien verbally, her words breathy and sultry, her hands clasping are her perky breasts, twisting her nipples through her sweaty top, another even stealthier hand, rubbing her clit through her pants, careful to remain unseen.

“Oh come on now Damo that didn’t hurt that badly.” She said reaching for the still grovelling and crying Damien, flipping him onto his back. To her surprise she gasped at the sight of it; he was hard.

As Damien fell to his back in the 25th minute of the workout, his thick, pre cum dripping boner stood firm, the uncut dick thick and veiny, the head pushed out from the foreskin, shiny with natural lube. For all his moaning and groaning, his pleas to stop and rest, Damien was like Ruby; he liked it!

“Oh you got a boner!” She said teasingly, grabbing the shaft tightly with one hand and smacking the sensitive head with the other.

“Please…don’t tell Sarah, she’ll cage me if she knows.” Damien begged, a sweaty, clammy hand touching Ruby’s.

“Sarah’s the instructor?” Ruby asked questioningly, Damien merely nodded.

“Well she did say that if you popped a boner I was supposed to beat it down.” Ruby replied suggestively, flicking his left testicle with hard, deliberate strikes.

As Damien flinched, tears rolling down his cheeks his dick hardened more, becoming a solid mass of masculinity above two swollen balls.

Ruby continued beating his ever reddening sack, the balls growing in size thanks to the immense swelling from various knees, punches, slaps and kicks. Despite his resounding pleas of pain and dire desire for rest he still endured. Ruby found it both admirable and incredibly sexy.

As the 30th minute approached Damien’s nads had swelled to incredible sizes, no longer the droopy loose sack it had once been. Now his balls were as red as raspberries and bigger than plums, the sack swollen, hanging hot, away from his sweat covered body.

“Had enough?” The sweat covered Ruby asked through heavy breaths, her tight booty shorts removed, the material completely soaked through, she now boxed his aching balls in nothing but a see through crop top and a soaked thong.

The other girls had began to slow as well, their ball boys replaced five or six times whereas Damien stayed firm. For a moment Ruby considered perhaps she was going soft on him, but after ripping in some forceful jabs sending his sack up into his ass, his body shaking all over in pain she smirked and realised it couldn’t be due to lack of trying.

She just had a good ball boy, one who had trained hard prior to their meeting and, had conditioned his body and balls to endure what most likely felt like torture but that ever throbbing boner made Ruby contemplate if it was all an act.

She could’ve sworn her last knee to his pitiful scrotum had released a moan or two but she had to deliver a third knee just to be sure. Any time it felt like she caught him in the act, the very next hit was met with a whimper or cry.

As Damien coddled his aching and bruised nuts on the cold gym floor Ruby leaned down, careful to be quick. She took his dick in her hand and began stroking him, the bounty of pre cum and her sweaty hand making her strokes glide like air across a flat field.

“You can stop pretending.” She whispered, stroking him quicker, his cock almost hurt it was so hard.

“If I tell the truth will you let me cum?” He said barely able to push the words out, his pride and balls both wounded.

Ruby kept her pace, focusing on his uber sensitive dickhead, the sensation driving him wild. Ruby watched with pleased eyes, her Pussy leaking heavily like a broken faucet at the sight of the broken man she had made.

His tear soaked cheeks, his puffy eyes and bright red balls made her clit twitch excitedly, she half enjoyed rewarding such a masochist who allowed her to throttle his sack for the better part of 35minutes straight.

She jacked him now, going the full length of his long meaty cock. His back arched, as if ready to shoot. Slowly she reached the base and squeezed hard with one hand, the other tapping his balls, sending him flailing like a kite caught in the wind.

“Please let me cum, please! It’s been so long miss.” Damien said, his tone needy and weirdly affectionate as if he were praising Ruby.

“My name’s Ruby darling remember?” Ruby continuing the painful squeeze.

“Miss Ruby please let me cum, I’ll be good I promise.” Damien said, the promise sounding weak and timid, like a scared boy asking his mother for a snack.

Ruby eyed the clock, 38 minutes, he had only two to go, which were quickly fading away.

“Can you cum on command?” She asked, Damien merely nodded back limply.

Ruby looked over her shoulders, slapping his sack hard to make him groan, the cover of their deeds unbroken. With haste she resumed jacking him, pulling her thong to the side to show him her sopping wet pussy.

“Look down, look at my pussy and cum.” Ruby ordered without a second thought.

Ruby watched with wide eyes as her ball boy did just as he was told, the mere glimpse of her heavenly pussy sent him over the edge, she pumped his cock, sending a bone chilling, earth shattering orgasm out of his cock and all over her hand and shirt. With her free hand she covered his moan, careful to stifle the moans lest they get caught.

As she jerked out the last morsels of his load she released him, grabbing her workout towel from her bag and wiping her hands and chest clean of his sticky white seed.

She quickly returned to him and cleaned him up, giving him a hard ball squeeze before helping him to his feet. The 39th minute ticked over. He stood on shaky gazelle-like legs, his dick now limp and droopy, his balls emptied of their seed yet beyond tender.

Ruby took a second to study the other women. They had all stripped down to their bras and sexy undergarments just as she had done, bouncing tits and thick juicy asses glistened with sweat, ladies with messy hair and rock hard nips.

Shoes had been discarded in favour of feet on ball action, some ladies had resorted to stomps to save their legs another hefty swing while others merely sat atop their ball boy who were positioned on all fours, while they drank their post workout drink.

As the timer for 40 minutes rang, near deafening all inside Ruby looked down the line of ball boys, only Damien remained standing.

“Time!” Called the instructor named Sarah who came back from a room nestled behind the gymnasium steps. She stood proudly with her hands on her hips, first eyeing her sweaty gym girls before turning her nose up and assessing the damage done to her boys, noting quickly only Damien was still standing.

“Is he the last one?” Sarah the instructor said walking past the broken and battered ball boys sprawled across the floor toward Ruby and Damien. With a quick and gentle nod Ruby acknowledged her.

“Well then he’s earned an orgasm. Ruby I think you’ll need to up your game if he survived the entire time.” Sarah said almost mockingly.

“There were a few before him, he just got lucky.” Ruby said, her eyes looking into Damien’s not Sarah’s.

“Well, either way, your form could use work.” Sarah said dismissively pointing at his balls as if conducting a post game analysis of where she went wrong.

Before Ruby could jump to her own defence Sarah took Damien’s limp dick and began stroking him.

“Doesn’t take long usually, these guys are pretty clogged up, so we should be done soon.” She said offhandedly, as if the ball boys were prejacs and gooners who exploded at the slightest womanly touch.

Ruby watched as Sarah aggressively yanked at his still limp penis, the post orgasm sensitivity causing Damien to shake wildly. Ruby’s sadistic clit fired up eagerly as she watched in thrilling anticipation as Sarah began, unbeknownst to her, giving Damien a post-orgasm handjob.

The scene was delicious, Damien grew semi hard, unable to fully reach critical mass without ballbusting, Sarah continued to work the upper shaft and head, Damien biting his lip holding back tears and screams at the synaptic torture of the post orgasm strokes. He was flopping around like a fish, floundering, trying to relieve himself from the sensory overload.

Ruby watched, her senses on fire as Sarah finally pumped his puffy sore dick to an orgasm, the cumshot beyond pitiful, his pain superseding any form of pleasure. As the shot released from his cock Sarah gave his balls a terrifyingly hard slap, flooring Damien instantly.

“Alright ladies showers!” Sarah said, fully ignoring the crying Damien behind her.

The girls all left their respective broken beta boys on the cold gym floor and headed inside the girls locker room, some stripping down before they had even entered the room.

Ruby ducked in fast, finding a shower with ease, she stripped quick placing her clothes and shoes haphazardly on the side table eager to keep the feelings and images fresh in her mind.

As the water began to jet out, Ruby ripped the shower head off its connective piece and lowered it down her body, washing the sweat down the drain in one smooth motion. As the head reached her feet she brought it up again, this time slowly, stopping right on her needy little clit. The waters pressure and temperature felt ever so inviting.

With the images of the intense Ballbusting and amazingly erotic post orgasm torture she pushed the jet head close, lighting her senses on fire. If she listened close enough she could still hear them groaning and crying. Ugh she thought. What a perfect end to a top notch workout….
