Penny’s first step in this session of the training would be very different to Amy’s. A weighted barbed chain had been threaded through several of her labia rings and the ends of the chain attached to her ankle. Her first step with the wire through her right pussy lip stretched the labia out and away from her body. The length the lip flesh stretched out was almost cartoonish; like something out of a sick comic book. The pink, tender flesh was pulled several inches away from her body as her knee jerked forward in the instinctive action to keep up with the now slowly moving treadmill.
This was by far the most extreme stretching she had received on her freshly modified lips up to this point. None of the pinching or pulling she had experienced so far had put as much stress on her netherregion as she now inflicted on herself just by walking.
It felt like the flesh would tear, had torn!
In truth, the strain put on the flesh would have caused it to be ripped from any other normal woman's body; without a Spatium injection into it. This nerve enriched skin would continue to stretch, each cell screaming in agony but in their tiny, microscopic bondage they were also tortured as they would not break, would not tear unless done so under the most extreme conditions possible.
The pain literally made Penny gag in her throat as her boot hit its mark on the treadmill. In slow motion horror, her mind affected by the drugs and the extreme duress, the treadmill slowly rolled under her, silently commanding another step.
A few more ragged, gasp inducing steps, the scuttling motion bringing her awareness panged to her bloated belly and the heavy cramp inducing liquid within. She now had three weighted points of gravity on her body: her two beachball size milk filled flesh udder and the less heavy sloshing gurgling belly filled with one of Kaya’s punishing solutions.
As the treadmill began its first minor increase in speed, the screen in front of Penny showed a close angle view of Claire; her entire face filled the screen towering over Penny like a vengeful goddess. Penny wailed, wanting to shrink away into a corner from the terrifying vision but being unable to even look away, captured and controlled as she was, she could only march on towards the spiteful face of her former best friend.
“This is your life now Penny.” Claire's voice, booming at her and echoing off the concrete walls. “You’re my pain puppet. You and your sister are my playthings to twist, jerk and scream. And if you break, that's ok. I’ll fix you, modify you, make you even better for my games. I have sooooo much planned for you Penny. We will be playing for a loooong time.”
In Amy’s room, Leo was tenderly getting ‘Sugarsquirts’ ready for her next attempt on the treadmill.
The thick, veiny vibrator was slowly inserted into the sopping pussy, the beautifully adorned and pierced lips parting to slickly accept its full girth. Amy’s eyelids fluttered at the overwhelming pleasure of being stuffed to the brim with cock, again.
Before driving the dildo all the way home, Leo attached a new strap just above her pubic area before feeding it down through her legs and through a connecting ring on the bottom of the dildo, before clipping the end of the strap to the bottom of her butt plug.
The dildo hung there loosely, the base of it hanging an inch or so out of Amy’s stretched quim, droplets glistening in the floodlight. Connecting another delicate, necklace-like chain to the dildo, he took the engorged, grape sized pierced clit between his thumb and forefinger. Rolling it around eliciting a moan from Amy as her eyes rolled in her head and thighs trembled.
Standing up, he looked deep into Amy’s glazed eyes, wondering if she really understood what was required of her next and what was going to happen.
The loose fitting of the appendage meant that as she was running on the treadmill, the vibrator would be bouncing up and down on the strap. Moving up and down, this would result in a small fucking motion as it would micro thrust in and out of Amy’s pussy. If this wasn’t enough, the movement would also tug and yank on the clit chain as she walked, effectively masturbating her most delicate nub in addition to the penetration.
He started the treadmill slow, just as before to observe this new setup on Amy.
The glazed, drug-addled look soon disappeared as Amy began to walk and she felt these overwhelming sensations. A very different kind of walk as the effect of her new bondage took hold. Leo watched her, making sure the straps were at the right tension and everything moving just as he wanted. Satisfied, he came close to Amy’s face and stroked her cheek.
“Now we start you again girly. You’re going to cum in this session, but you must keep the pace going or you’ll get some nasty shocks in your bum just like before. Have fun.” As he prepared the bitgag back up into her mouth, he held up another aphrodisiac laced sugarcube in front of Amy’s face.
She shied backwards, shaking her head, stamping her hooves, pleading with her eyes as she shook her pretty, perky pony tits at Trainer Leo in a desperate attempt to secure his mercy...
But the man's fingers were nimble - devastatingly nimble, so nimble Amy could not, in her still cum-drunk state, resist a brief image of his fingers strumming blissfully across her aching little clit... And as she lost herself in that image and the tension in her jaw eased. Leo tucked the horrible sugarcube behind her teeth and trapped it in place with the bit gag, fizzing against her tongue, oozing its sticky secretions down her helpless throat.
As Amy felt the sweetness dissolve on her tongue, the treadmill started its first minor speed up. And once again, the beautiful, hideous machinery of Cruciatu Prime slid into almost effortless motion for both girls.
Not simply the physical machinery; the motors and cameras whirring in mechanical perfection to bring both the sobbing sister's up to a sprint in a steady acceleration of stamping hooves did their job with absolutely flawless precision. But the psychological machinery too.
Amy knew the agony she'd suffer if she came without permission. She knew how hideously she'd humiliated herself as Leo fucked her, how disgustingly slick her own thighs had become, basted and drooling juice from her throbbing dripping cunt. She knew how Buttercunt had been broken by the industrial-grade aphrodisiacs and how sickeningly close she was to a similar fate, to living her life as a brainless, desperate, dripping mare-in-heat barely able even to beg for release on the promise she'd be a good Sugarsquirts.
Between the torture and the fear and the arousal, Amy knew how close she was to losing herself in this horrible, subterranean prison with its treadmills and concrete and smothering, stinking air laced through with the suffocating smog of her own soaking sex.
The tears came into Amy's eyes almost instantly as her heart pounded with fear.
And then she began to run. Exhausted, broken, terrified... And running faster and faster and faster as she realised that doing so meant she would get FUCKED. Hating herself at every step and utterly, utterly helpless to stop as the aphrodisiacs pumped faster and faster through her bloodstream.
The psychological machinery intent on tearing Amy apart.
It was no less insidious, no less evil for poor Penny, though her sister's route to destruction was focused on overloading her pussy with pleasure not pain.
Penny knew full well that to resist, to stumble, to hesitate would mean agony. She knew as if she'd been drilled from birth that Kaya would brook no possible rebellion in any case, but the Training Mistress was so obviously in awe of Claire, so desperate to make herself a trusted lieutenant of Madam Director Buckley that she would break Penny in an instant rather than allow the pony's pleading or broken muscles to refuse to obey as the treadmill accelerated into humming motion.
So Penny ran.
Each foot forward made her screech in pain, her eyes wide, her viciously bit-gagged mouth gumming frantically at the cruel intruder pinning her tongue into silent helplessness as her already pronounced, eternally shameful lips jerked down as if hauling a ten-ton weight.
Between the heavy artificial hoof of her boot, the force with which Penny was obliged to sprint, and the sheer weight of muscle and bone in her long olive-toned leg, the effect on Penny's cunt was the equivalent of her heavily pierced, swollen, throbbing labia being suddenly clamped and then catapulted into downward motion.
The jolts almost brought her to her knees. Instead she swung, screaming, swaying in the harness as she kicked and flailed for balance, every jerk of her thighs snapping her cuntlips down as the evil linked chain seesawed through the fetters of her ankles, tugging down hard on the Spatium-suffused flesh on either side, every kick and every step making a mockery of Penny's most shameful physical trait.
Before her blurred and tear-filled eyes Penny was forced to watch Claire cackle, to see her best friend ogle her distended cunt as one flapping inner fold and then the other was tugged mercilessly down, stretched along the length of Penny's aching thighs in a shameful, sticky, staggeringly painful succession of jolts, each more painful than the last.
Claire's mockery only added to the agony, the pain in her body building with every step until Penny simply could not tell which was worse.
The pain in her straining labia as she was made to deform and abuse her own suffering sex, jerking herself almost to the floor as she trampled her own cuntlips into an abyss of agony?
The pain in her studded, pierced ass as her straining over-filled, bloated guts cramped and churned, the hideously sloshing water setting a nauseating horror inside her own body as her tightly sealed hole strained in futile, cramping desperation against the relentlessly massive plug deforming and cutting her puckered ass against its wicked studs?
The pain in her bloated, ballooning breasts, the increasingly swollen udders that were so deforming her body, that jolted and shook with every agonising step and which seemed against all possibility to be growing fuller, harder, to throb more and more with every ragged breath?
Or the pain in her heart. The pain she felt at seeing the beautiful redhead, the woman she'd trusted as her most intimate friend, her closest companion, her most reliable source of relaxation and happiness, laughing and mocking and revelling in Penny's torment. Needling her misery, gloating over her despair, and sealing her fate with that hideous, horrifying promise: This is your life now, Penny. You're my pain puppet.
It was enough to break the strongest will, and poor Penny's will was nowhere near as strong as it had once been.
With a superhuman effort the punished pony strained and struggled until her tongue could move and she cast her wide green eyes up at the screen with a wail of absolute animal fear.
"Chlairee!! Pleeeathee!!! My CUUUUUUNNTTTTT PLEAGHE AAAAIIIIGHHHHHHHHHHH!!!!"
...and the treadmill ran on relentlessly.
Clapclopclapclopclapclopclapclopclap....
Every flurried step, the weighty flesh bags attached to Penny’s chest slammed down, the movement sending an earthquake of pain reverberating through her body, an agonising ripple emanating from her crushed nipples. \
Each jostle of her spine threatened to make her tumble which she regularly did only to be caught by the head ‘safety harness’.
As she was yanked upright, head held high and forced upwards by the tight posture collar, her balance was all off and her bloated breasts and belly swayed this way and that as she tried desperately to correct herself. As she started the stumble, the heat lamps clanked on and her already sweaty and flushed flesh started to feel like it was burning.
Her tortured mind scrambled, begged for something to make it stop. But she couldn’t do anything; she was helpless. Dragged on by the internal machines her mind raced, starting to break, she could only focus on small thoughts.
So hot. So tired. Legs. Pussy. Pain. God…Claire... Help...Hell...Dying….
Her weight went completely off balance and she twisted, her legs leaving the treadmill and spasming in the air as she was again shocked in her anus, sending a stabbing pain up her back. However, this time it was too much, the pain too great. She bounced in midair, suspended as the shocks hit her over and over, losing control of the ability to try and correct herself on the treadmill, her legs refusing to obey her.
As she hung there, stabbed by a million angry invisible needles of electrical pain, her flailing legs stretching her cunt lips in every direction possible, Claire beamed down at her in glee. In her drugged state, Penny felt like a tiny insignificant fly caught in Claire's spider webs, her body wracked and tortured with venom.
Amy was hardly faring better, although the two girls were having very different experiences. Penny’s gait was a jerking flail, each step marking her arch and squeal in pain while simultaneously and instinctively trying to get away from the burning stabbing pain of her sensitive labia being stretched.
Struggling and stumbling like her sister, Amy’s movements were wiggling, jiggling, shaking, trembling as she hopelessly fought against the slick dildo that was sliding in and out of her with every step forward.
Each overwhelming wave of pleasure made her bite down harder on her gag, and clench her lower body; which had the unfortunate effect of clenching her anus tight around the uncomfortable tail plug but also grip the cock in her pussy harder, only increasing the ever building waves of pleasure. The bouncing of the dildo was tugging at her clit every second, the tiny nub yanked and stretched and teased.
She ground her teeth into the gag, trying to fight the building climax and the light headedness she was feeling.
Tried to do anything to stop herself from cumming, even focusing on the painful parts and the exhaustion.
It was no use. The drug had her. Even without the sugar cubes, she would likely have cum just from the dildo and clit stimulation. The increased effect of the aphrodisiac meant that the orgasm would be longer, more powerful and meant that she would also come over and over while squirting away her precious hydration at the same time.
She knew it was hopeless to fight it. Her eyes darting around from a saviour, the only thing she could see was her horribly tortured sister, wide eyed and panicked starting back at her from the TV screen. She steadied her mind as best she could and looked into the screen, hoping her captors were still around and would give her some kind of sign that she had permission to orgasm.
“PPPPPPLLLLLSSSS-HUFF HUFF-PPPPPPLLLLLSS. LLLLLLLLLOOOO-MMMSSHHTRRRRR!!!! LLLLLLL HUFFHUFF - MMMMMM CHHHHUUUUMMMMM-PPPPPLLLLLSSSSCHHHH!"
To Amy's amazement, the screen changed before her eyes as she gave another despairing, exhausted howl of "*PLLLLLLLSSSSHHHHSSSSPPPLLLSSSSSSEEEEE!!"
In an instant the terrible sight of her sister jerking helplessly in her harness vanished, the high-def horror of Penny's warped body and grotesque struggles beneath the hotlamps disappearing as the feed changed - and in Penny's place loomed Claire, her beautiful smile a vision of absolute delight that struck the chill of absolute dread into Amy's overheated core.
"Why, if it isn't my beautiful pony Sugarsquirts" Claire purred, licking her lips as she deliberately drank in Amy's desperation. "Such a goooood pony asking for permission! You know how things work here, don't you? Don't you, yes you do!! My lovely Sugarsquirts running so hard that her pretty little quim is simply drooling down her thighs!"
Claire grinned, a towering giant on the massive wall screen, mocking Amy's helplessness, grinding home the obscene name Leo had assigned the terrified young woman as Amy kept running, whimpering as her teeth bit hard into the gag, the absolute struggle for obedience obvious in the tension of Amy's face, the straining sinews of her neck as she stared into the camera, silently begging, helplessly sprinting as the devilish dildo bounced and thrust, filling her with every stride and jerking at her daintily pierced clit until the poor pony's eyes were rolling madly in her skull.
"Should I let you cum, Sugarsquirts?" Claire asked, smiling sweetly "Would you like that? Would you like to surrender to the pleasure of being my pony? My plaything? My pet?"
Claire giggled again, and shook her head.
"No. No not juuuust yet, Sugarsquirts! I don't know if you remember but you were very bad going behind my back so your nasty big sister could try and betray me!"
For an instant the pleasure and amusement vanished from the redhead's face, replaced with a cold, hard hate that made poor Amy feel even smaller, a mere ant flailing as her captor focused her full hate through the magnifying glass of the screen, and then instantly Claire began to laugh again.
"But that's hardly your fault Sugarsquirts! You were only looking out for your sister, right? I tell you what... You don't get to cum until Penny does her job and runs for me, okay? And if you can't obey, Sugarsquirts, well..."
Claire chuckled again, and brought her hand up to her mouth, slowly and daintily sucking them clean of a dripping clear liquid with such studied precision Amy almost orgasmed at the sight, and continued...
"...well then I'm afraid you'll let your poor helpless sister down very badly indeed..."
Amy whimpered, shuddered, stumbled - and kept running, in almost physical pain from the sheer impossible effort of controlling her urge to cum as Claire cut the cameras back to Penny.
To Amy's utter dismay, her sister was still thrashing in her harness, suspended, struggling, straining to bring her muscles under control and force her feet down to the treadmill, but her body simply couldn't answer any longer, couldn't bear the agony in her calves, in the stretched and straining tendons of her feet in the sadistic ballet-formed hoof-boots, couldn't force herself to stretch her chained, captive cuntlips by stamping down on that hideous chain once more.
She simply hung there, jerking helplessly as the cameras captured her agony and Claire began to hum a jaunty jazzy tune, counting the beat under her breath.
"A-one and a-two and a-one-two-three-fo--"
"NNNNAAAAAIIIIIICCCUUUUMMMMMNNNNNNGGGGGGGGG!!!!" Amy wailed, stopping dead on the treadmill as her legs buckled, her eyes rolled back, and her overloaded, drug-dripping cunt clamped down hard around the bouncing dildo, stopping it dead in its path as her core clenched and her cum burst from within her, juices flooding the floor in a steaming smog of sexual frustration and arousal that wiped Amy's mind of any thought but the supernova of overstimulated pleasure that swamped all conscious thought and rewrote it in the absolute, undeniable force of her own pleasure and despair.
Despair at her failing, at her disobedience, at her weakness... At her betrayal as Claire's laughter filled the room in low, husky gasps as Amy's effective goddess orgasmed in a rolling, luxuriant, controlled cum of her own cruel choosing.
"Ohhhhh, pooooor Sugarsquirts" Claire moaned "you don't love your sister as much as your own cunt, do you? No. No you don't. But that's okay."
Claire's voice dropped to a stage whisper as she added "Nobody else here cares about Penny either."
Panting, sobbing, still squirting as the drug brutally milked Amy's body for every drop of orgasmic secretions she could possibly surrender, Amy watched in horror as a second bank of headlamps burst into life with a crunk that was audible even through the concrete wall. On the screen before her, Penny's normally olive flesh shifted from an orange-pink glow to a livid red and fresh beads of sweat broke out on her flesh, highlighting her desperate, dehydrated struggles.
"Nooohhhhh" Amy gurgled pathetically "Mmeeeeehhhplssshhhe. Pnishhhh meehhh. Nohhhpnnyy. Meehhhhh...."
But Claire didn't even bother to laugh in response. The avenging redhead's fingers were fully occupied fucking her own soaking snatch as she overrode the system warning and set Penny's punishment cycle to maximum.
For Penny, still swimming helplessly in mid air, deafened by the sound of her sister cumming and the sizzle of her own skin as sweat turned to choking steam in the oven atmosphere of the cell, resuming her run was already impossible.
Now, the punishment became positively inhuman.
Above her, she knew Claire was beaming down, revelling in Penny's punishment. Behind her, she knew Kaya was watching.
But Penny could do nothing, absolutely nothing to stop the pain or obey her orders or even make Claire understand that she'd won, that Penny would never cheat again, never do anything wrong or cruel or selfish ever again, that if Claire would just stop the torture for a second Penny would do anything...
Instead the electric shocks got worse, instantly worse.
The burst of fire that exploded inside her ass made Penny convulse so severely that the cunt-chain stretched her labia almost to her knees before she crunched up into a screaming, shrieking ball of anguish and before she even had her breath back the burst came again, setting Penny's already racing heart into a sprint of such intensity her blurry vision swam in a thumping spiral, beating time with her staccato pulse as the heat built remorselessly, mounting beyond the uttermost limits of any human endurance. Penny's body dripped with sweat, the salty perspiration sizzling as electric arcs coursed across her olive skin in skittering bursts of pain.
Even Kaya's face was turning white, the training Mistress's arousal and awe almost coming into conflict with what little conscience the sadist possessed - though not so closely she dared say anything to disrupt her blossoming relationship with the beautiful Director Buckley.
Even so, Kaya was biting her lower lip with more than simple arousal when Penny's gagged mouth opened in an enormous scream of electrical agony, sparks arcing obscenely from the metal studs around her ass to the swinging, sickeningly stretched lips straining as the Pony's legs thrashed so hard her stretched labia became an obscenely tortured puppet --
--and then there was silence as Penny's struggles ceased instantly, her whole struggling body limp despite the obscene crack-crack-crack of discharging current.
The long, deafening silence was broken by a horrified wail of gagged despair as the still-cumming Sugarsquirts bore witness to her sister's inhuman suffering, and in the second after Kaya glanced at the camera, Claire's voice crackled in her earpiece, ragged and husky with passion: "Okay."
Kaya smashed the alarm button instantly, and the heat lamps snapped off replaced with the whooshing whine of industrial AC as massive ceiling units began to hammer the heat of the cell down from its oven-like heights to an equally merciless proximity to freezing, while the electromagnet for Penny's cell door immediately disengaged, inset lights in the corridor ceiling highlighting the way for Nurse Taylor's emergency response teams.
Even knowing Penny was far beyond feeling the pain she so revelled in giving her, Kaya couldn't help grabbing the pony's grotesquely large clit ring and giving it a cruel twist that set the hanging pony spinning in her unconscious oblivion.
And over the sound of Amy's hysterical, orgasmic screams of horror, the sound of Claire's approving laughter was enough to trigger Kaya's own orgasm as she kept Penny swinging like the movement of an obscene carriage clock, beating the time of her own neverending destruction.
The on-call nurses responded to the alarm professionally; not being gentle with Penny, nor cruel. The alarm was silenced and Penny assessment began as she hung there twitching.
They removed the collar to assist with breathing, checked the pupils and her heart rate as Kaya watched nervously...She knew she should not be blamed for Claire taking control and pushing Penny beyond her limits… But she did not want to give anyone, anywhere in the company a reason to put her methods under the magnifying glass. She gulped and her own heartbeat started to race. It wasn’t completely unheard of for former Cruiciatu employees to fuck up so badly that they ended up in the system.
As if reading her mind, Claire gazed benevolently down from the screen at her. Kaya couldn’t help feeling a small pang of fear. “I’m so sorry Kaya, i just got a little bit carried away there” Claire giggled, as if she had split a drink at a bar instead of almost electrocuting a woman to death. “I do of course take full responsibility and this won’t reflect on you at all!” Claire's beaming smile took away Kaya’s uneasiness and her mood was further restored as the nurses gave her a nod indicating that Penny was ok and would recover.
The nurses began disconnecting the harness attachments as a stretcher was wheeled in. “I’m very happy with your methods thus far and you’ll have my full support going forw--Hmmmm. Seems like we’ve really set Sugarsquirts off next door!
Kaya was suddenly aware of the muffled sounds of Amy through the wall in the next room, just as Claire brought vision and audio of the sister up on the screen. Boots still slamming on the treadmill in panic, she seemed to be in a constant state of a galloping orgasm.
Hips gyrating, she was screaming in ecstasty and pain as she would trip and stumble then arch forward as she was shocked, regain her footing and repeat the demented run again and again. Juices dripped from her thighs in small pitiful spurts, looking like she was pissing herself every few seconds but was actually her own wetness from the drug and hormone cocktail. It did not seem like Amy was aware of anything at the moment other than running and cumming, her sister's torment lost in a haze of exhaustion.
“I think that should be enough for today. Amy could probably use some water as she’s lost a lot of ...fluid haha!”
The treadmill in Amy’s room slowed from a whine to a hum as the belt returned to a walking pace. Sobbing and coughing as much as her haggard lungs would let her, Amy’s locomotion returned to a sexy strut. No longer a blur, the crotch dildo glistened with juices as it slipped in and out with every step.
No longer being fucked fast, Amy’s aching vagina was still getting a lot of pleasure from the intruder. Instead of a fast jackhammer fucking is was now slow and sensual. She clenched and moaned, shaking her head as another orgasm started to build.
Claire was addressing Kaya in the room next door “Arrangements have been made for Penny in line with the medical department's recommendations. No need to worry about her, she’ll be taken off and prepped for her initial milking before there is duct damage”
Penny was not strapped to the stretcher, the huge hard mounds of her tight tits looking like they would crush her torso. Though less pronounced than her breasts, her belly was still bloated with the enema. Kaya caught one last glimpse of her face as she was wheeled out - even in unconsciousness there still seemed to be a grimace of pain…
Kaya was alone with Claire on the screen now, with the inset of Amy’s mewing as she was still trying to fight the coming climax.
“Feel free to do what you want with dear Sugarsquirts tonight, make sure she is disciplined for failing to follow instructions. I’ll need her for something I have planned tomorrow but she can be in any condition” Claire flicked her red hair back over her shoulders with a carefree sigh of contentment as her eyes flicked to Amy’s screen again.
“Gosh, she’s REALLY having fun. We’ll have to go back across the footage and see how many infractions shes has”
Right on cue, Amy’s squeals were coming closer and closer together as her walk became a shuffle as she squeezed and clenched her legs together uncontrollably. A second later a trickle down her still swinging legs as she came, again.
“Better get her collected and down to her room for the night. We’ll speak soon, ok? Keep up the work Kaya!”
