"Wakey, wakey, Diamond Tiara," crooned Apple Bloom in her usual Southern drawl.

The pony in question stirred, groaning slightly at the stiffness she felt in her neck. As her eyes groggily opened she took in the terrified face of her one and only friend: Silver Spoon. The steely grey filly's wild and frightened eyes stared back at her from behind her usual thick rimmed glasses.

"Silver... what... what's going on?" mumbled Diamond Tiara, still in the process of awakening from her chemically induced sleep.

Silver Spoon did not reply. The filly was being held in iron stocks, the kind that DT had seen in the old school history books about medieval times where ponies would have tomatoes and such thrown at them for committing some crime. The stocks were little more than iron bars with three holes drilled in them, one for the filly's head and two smaller ones to hold her forehooves, the entire thing bolted to the concrete floor beneath them.

It took Diamond Tiara a few seconds to realize that she too was being held in an identical manner, forced to face her friend and unable to move her upper body an inch. She kicked her back legs in fright but found they were shackled together, limiting her movements even further.

"I demand to know what's going on!" she snapped, twisting her head in an effort to look around, "If my daddy finds out about this then there'll be heck to pay!"

She could hear Apple Bloom giggling somewhere outside of her field of vision. Was this all just a prank? Had those stupid blank flanks finally decided to take their revenge?

"Okay, Apple Bloom. This is mandrake root extract which acts as a-"

"Muscle relaxer!"

"Very good! You're learning so quickly! How about this one?"

"Oh... um... that's... uh... blue willow bark pulp and uh... smells like... poison ivy extract? Oh! Wait! This is the one that makes 'em all itchy, ain't it?"

"Exactly!"

The second voice belonged to Twilight Sparkle, the town librarian. It seemed to Diamond Tiara that she was giving some kind of a lesson in potions or chemistry or something. That egg-head was always trying to teach other ponies about pointless things. DT rolled her eyes. So this was all just some lame lesson from the town's biggest nerd and her dweeb apprentice. How pathetic.

"And this one?" asked Twilight, Diamond could not see her but she could tell from her voice she was grinning broadly.

"That's an... aphro-watchamacallit... the one that turns ponies on. The one you used on me on the firs' day. Are ya gonna use all that's in that bottle? Ain't that a bit much?" replied Apple Bloom, sounding worried.

"Maybe. We'll find out. Experimentation is the heart of scientific inquiry, after all. Oh! She's awake. We can begin."

DT listened to the hoofsteps approaching her from behind.

"You two lamekins had better have a good reason for locking me up like this or you're both gonna regret it," snarled Diamond Tiara. Something about the look of horror on Silver's face was worrying her. She wished she could turn her head and look behind her at the two of them.

"Oh, we've got a great reason," giggled Apple Bloom.

"Diamond... they... they have... they both have..." stuttered Silver Spoon, pausing mid-sentence to retch in disgust.

"Both have what?" Diamond Tiara did not have to wait long for the answer.

Apple Bloom stepped out in front of her, striding through the space between the two stockaded fillies. Swinging underneath the red-maned mare's legs was cock. A big, greasy, hairless horse cock that looked as if it had been transplanted from between the legs of a full grown stallion. Its size was almost comically out of proportion on the small filly, the shaft alone longer than the length of her body from head to flank. The tip of it jutted out from between her forehooves, its stiffness keeping it glued to her belly and chest. Unlike normal stallionhoods this one sported a wrinkled foreskin that hung loosely from it, flowering off the tip. The balls looked painfully swollen, veins running across their surface like rivers viewed from high in the sky. Its skin was a sickly yellow that matched her fur, albeit a few shades darker. The tip of it, which peeked out at her from behind the wrinkled folds of foreskin, was a bright and angry red.

Diamond Tiara gulped down the rising bile she tasted in the back of her throat. She could smell it from where she was shackled. A pungent sweet and sour tang that filled her nostrils and made her eyes water.

"That's so disgusting I can't even laugh!" she spat, literally spat onto the concrete beneath her, "Was that the result of some failed experiment you did? Serves you right for fooling around with plants and stuff all the time! Now let me out of here so I can go home and vomit!"

DT glared all her venom at the young futa-filly who stood proudly before her but all she illicited was a chuckle from Twilight.

"You were right, Apple Bloom. She certainly does have quite a mouth on her. We'll just have to find a better use for that mouth," said the purple unicorn as she stepped out to join Apple Bloom.

DT knew now why Silver Spoon had been looking so alarmed. Twilight too, sported and enormous member, not quite as big as Apple Bloom's. The librarian's mane was frayed and ruffled and she had a... disturbing demeanour about her. She held several jars and syringes floating around her head with magic, each one containing a different coloured gel or elixir.

"Okay, fillies! Listen closely. Apple Bloom over here has a bit of a problem, as I'm sure you can smell. Her penis is developing abnormal quantities of smegma. She needs to be regularly cleaned and you two are on duty to do that for her. Now one of you will clean out her foreskin and the other will help me with my experiments in the meantime. So which one of you would like to volunteer?" grinned Miss Sparkle, tilting her head and flitting her eyes between the two of them.

A use for that mouth... clean out smegma... smell... the gears of Diamond Tiara's mind desperately turned as she processed what she had just heard. Were they actually proposing that one of the two of them... ? The mere possibility of it made her feel sick to her core. She decided without hesitation to betray her friend.

"I want to help with the experiments!" she cried, "Silver will do the smegma!"

"What?!" Silver squirmed and struggled but the stocks held her fast, "Diamond!"

Diamond didn't waste her time apologizing. Whatever dark deeds were about to be done she would not be the one to clean some blank flanks disgusting dick cheese.

"You heard her, Apple Bloom," Twilight trotted over to Diamond Tiara and the youngest member of the Apple Family waddled over to Silver Spoon, her cock already beginning to twitch with excitement.

"Did you overhear my conversation with Apple Bloom?" a twisted smile was tugging at the corners of Twilight's lips as she held up a glass vial with a grey-green slime coating its insides, "This is called itch bane. It produces an intense itching sensation on the skin that can be quite pleasing... if you're able to scratch it that is... let's put some on you and see how it goes."

"Twilight! Why are you doing this? Wait! Stop! Where are you going?" Diamond's protestations fell on deaf ears as Twilight circled round behind her. She trembled as she felt her tail being lifted into the air with telekinetic magic, "N-n-no! You can't put it... there. You can't! You can't! I'll tell my daddy! He'll sue you for all you're worth if you don't stop right now-"

She felt a moistness being smeared on the undeveloped lips of her tiny filly slit. Then her entire body stiffened as the lips of her cunny were spread and a dollop of the stuff was pushed inside her. She gasped at how cold it was.

In front of her she could see Apple Bloom gripping her throbbing protuberance in both hooves and easing back the foreskin. The bright redness of her tip was exposed to the air and even from an angle Diamond Tiara. It was decorated with a number of maggot sized blobs of cream coloured secretions. The stench of her cock had increased tenfold and she could only imagine what Silver Spoon would be smelling the second the filly stopped holding her breath.

"Twahlaht, she won't open her mouth fer me," Apple Bloom sadly prodded Silver Spoon's clenched lips with the repulsive tip of her unclean cock.

"Not a problem. Apply some muscle relaxant to her jaw, neck and below the ears!" Twilight levitated over the mandrake root extract, a brown cream in a glass jar.

Apple Bloom grinned. Her love of brewing potions had only grown during the insanity that had consumed the past few days. She used her tail as an improvised paintbrush to avoid touching the stuff directly and dabbed it on the areas that her teacher had suggested.

Diamond Tiara watched as her friends face suddenly slackened at the touch of the balm. Magically enhances muscle relaxant works very quickly. As hard as the silver filly tried she could not keep her jaw clenched shut and in mere moments it hung wide open, a thin trail of saliva running down her chin and dripping onto the floor. Apple Bloom lined up the tip of her smegma smothered cock with Silver's now helpless mouth.

A prickling, itching, tickling sensation had been building, spreading through Diamond's nether regions as she watched the scene unfold. Her legs squirmed unconsciously but it did little to alleviate the sensation. It was the itchiness of having rolled in grass for several hours, of a bee sting that was several days old, of a hundred mosquito bites, of a brush with nettles and poison ivy all rolled into one and concentrated on her virgin pussy.

She squeaked and attempted to slap at her fillyhood with her tail in an effort to provide some small relief. But Twilight held her tail up with magic, keeping her from even the most basic alleviation.

"Looks like it's working nicely. Everything's going as planned. How are things with you Apple Bloom?" Twilight sniggered as she watched the pink filly's tail hole clench from the overwhelming sensation.

"She's pullin' her tongue way back into her mouth so she don't have to taste it. But tha's okay. I'll jus' push it in a little deeper... ah..." Apple Bloom shivered as Silver Spoon's teeth scraped along her shaft. The poor filly couldn't bite down with her jaw completely powerless and her violator was using her top row of teeth to scrape off dick cheese and then push it into her mouth with the tip. She was effectively being spoon fed the repugnant substance by the very same cock that had produced it.

Silver Spoon's glasses had steamed up and were now completely white but Diamond could hear her muffled wordless moans fill the room. She couldn't use her tongue to push the sickening gunk out of her mouth without tasting it, nor could she push it past the intruding head of Apple Bloom's new friend. There was only one place the clumps of smegma were going from here. And that was down her throat.

"Twilight... scratch it... scratch it, scratch it, scratch it, scratch it, SCRATCH IT! Now! Now! NOW! Agh!" Diamond had bitten her tongue as she writhed in the stocks. The intensity of the itching seemed to double with each passing moment and Diamond could take not a single second more of it.

Her eyes welled up with tears, not even able to concentrate on the blurred vision of Apple Bloom gliding her cock into her best friends mouth, Diamond Tiara's mind was consumed with the itching. Her legs writhed and her hips thrust at the air, unable to grind against the floor with Twilight holding her tail aloft, unable to reach back and touch it herself due to both her forelegs being bound in the stocks and both her back legs shackled.

"You didn't say the magic words," Twilight taunted, her words punctuated by the sound of Silver Spoon gulping down the filth.

"Please! Please! Pretty please! Pretty please with sugar on top! I'll do anything! Please!"

"I've studied magic for years and those don't sound like any magic words I've ever heard. But still... I suppose I should give you something to take your mind off it," Twilight stabbed a syringe through the cork top of a glass flask and filled it with a pink liquid.

She pulled the needle out and squirted a few drops into the air and then stepped back around behind DT. Diamond felt her flank being held motionless with magic and then a stinging on her right flank. She bit her lip and whimpered as she felt the syringe being emptied into her veins, its coldness spreading throughout her.

"Will it... will it make the itchiness stop?" she asked, desperately.

"Nope!" replied Twilight.

Apple Bloom sighed with satisfaction as she bucked her hips into the mouth of the filly who had bullied her for the past two years. She'd spread some more of the relaxant onto Silver's throat so that the very young mare could accommodate her shaft almost half the way down to her bloated ball sack. As Silver's slobber dribbled down her chin Apple Bloom reached down and wiped the steam off the filly's glasses. She wanted her to look her in the eye. So that she would forever know who owned her from now on.

Silver was being good. Her tongue flattened to the bottom of her relaxed jaw, her throat bulging as the massive cock plunged down her wind pipe. Apple Bloom felt a shock of pleasure each time the tip of her cock scraped past the filly's tonsils and dived into her warm moist maw. She slid a little deeper with each thrust. Soon she would start fucking the filly's stomach. Soon.

"Look me in the eye... yeah... tha's right... look up at me... ah... good girl..." the deep satisfaction of fucking this filly's mouth was quickly driving her to the edge, "You munched down all my smegma like you loved it... Ah think that can be yer job from now on... don't close yer eyes... keep 'em open and lookin' at me... tha's right... ye'll be mah little cock cleaner from now on... we'll keep yer mouth relaxed like this permanently... no need for you to talk ever again... tha's good..."

She lovingly caressed Silver's cheek, all the years of resentment towards the yes-mare vanishing as she rode to the brink of orgasm.

Twilight administered the third full syringe of aphrodisiac. She was curious to see if it was possible to overdose on the stuff. The pink filly seemed to still be conscious but was gushing little rivers of love juice down her legs and into a puddle that she was splashing her back hooves in. Her movements were different to when she had simply been itching. Now her hips bucked up and down, subconsciously imitating sex. The large amount of filly cum had all but washed away the itch bane but its effects should still remain. Diamond was lost in a cloud of itchiness and extreme arousal. The filly's eyes were glued to Apple Bloom's balls as they swung back and forth, bumping her best friend's chin.

"So... what's the magic word, Diamond?" said Twilight, filling up a fourth syringe.

"D-d-dick..." DT was slurring her words, her pink, moist cunny rapidly winking at the air.

"What about dick?" Twilight stuck in the fourth syringe worth of aphrodisiac and emptied its contents into the once arrogant earth pony. Diamond didn't even notice the pain of the injection.

"Need... dick... dick... need... now..." strings of drool hung from her chin as her hungry gaze focused on Apple Bloom.

"Okay, Apple Bloom. That's enough," said Twilight, firmly.

"Awww..." with painful reluctance she withdrew her length. Silver hacked and coughed, her jaw still paralyzed and useless.

"Now I think we will pose the same question again. Which one of you wants to take Apple Bloom's cock and which one of you wants to play with me instead?" Twilight was rock hard, oozing precum down her purple shaft, "Silver Spoon? Which would you prefer?"

"Uuuuaaaaagh aaaaooooaaaaagh ruuuuugh," moaned Silver, her tongue strained and exhausted from fighting and eventually losing to the monster cock that had just pounded her oesophagus and left her jaw unusable.

"Looks like Silver doesn't mind either way. How about you, Diamond?" Twilight turned back to her test subject.

"D-d-dick... give me dick... please... do me... I want... me... dick... please..." a chain of barely intelligible words flowed from Diamond's quivering lips as she panted and wiggled her flank, "Need... need... please... dick..."

"Mah pleasure, Diamond Tiara. All ya had to do wus ask!" Apple Bloom ran round so quickly she almost slipped in the puddle of filly cum that DT had leaked onto the floor.

"I'll play with Silver then," said Twilight, filling up syringe with mandrake root extract.

Apple Bloom placed her front hooves on Diamond's flank and positioned herself at the mouth of the starving filly pussy.

"Ah've always wanted this. Always wanted to have you. Ah told mahself Ah wus crazy for wantin' somepony as horrible as you but now Ah understand. Yer gonna be a perfect breeding mare fer me. Both of y'all. I'll ride you until you forget who you were and you can only live for mah cock," she gave the filly's flank a tender squeeze.

"I think Apple Bloom was right. I like the idea of you being paralyzed permanently. A dutch wife for whoever might want one. Just a sex toy to be used, washed and locked in a closet somewhere. We'll impregnate you, of course, but I won't bother using aphrodisiac on you. It doesn't matter whether you enjoy this. You're here to be our cum dump and nothing more," Twilight whispered the words, almost to herself, as she injected the mandrake route into Silver's flank, "I'll give you a dose of this stuff every hour on the hour. After a day or two the effects will be permanent. Enjoy your new life as a doll."

Apple Bloom thrust into Diamond, tearing past the filly's hymen without a moment's hesitation.

"Yer friend brought me pretty close... Ah don't know how long Ah can last... but Ah guess it don't matter... ye've been stuck in an almost constant orgasm anyway... and Ah'm only interested in gettin' ya pregnant... they say filly's can get pregnant the moment they get their cutie marks... you always teased me 'bout not getting mine... but Ah think Ah'll get it pretty soon... and it'll be fer rapin' sluts like you... you even listenin' tah me?" Apple Bloom hammered into Diamond once more with each sentence she spoke.

Diamond's unbearably tight cunt pulled back the foreskin on each push, ensuring that the bare and sensitive tip was what powered its way into the womb. DT's pussy was too shallow by half to take the entirety of Apple Bloom's length but she didn't seem to care. She didn't care about anything anymore.

The itch had been scratched and now it was simply ecstasy.

"Ah you're all relaxed now... hmm... usually a filly would be too tight to take it up the ass but with you all limp and floppy like this... hmm..." Twilight smeared a pea sized blob of the itch bane on her own cock for lubrication, she flinched as the itching sensation spread through her shaft. She touched the tip of her cock to Silver's tail hole, "This is going to leave you itchy as all hell... too bad you won't be able to scratch it..."

Twilight eased her weight behind the shaft, pushing it into the filly's ass. It was still pleasantly firm even with the filly having lost all muscle control. She silently thanked her foresight. She'd given both filly's enema's while they had been unconscious. Twilight always prepared for every eventuality. She settled into an easy rhythm of thrusts, revelling in the dying whimpers and moans of her prey. Soon the mandrake root would spread through her whole body. Soon she wouldn't even be able to moan.

Twilight watched Apple Bloom with pride. The two were matching thrusts now. Teacher and student, lost in each other's eyes as they fucked their new filly spunk containers.

"Twahlaht, Ah'm gettin' close!"

"Me too... I was stroking myself while I watched you fuck this whore's throat."

"Ah wanna.. cum together... with you..."

"With me? But what about your toy?"

"She's been cummin' this whole time."

The two conversed casually as they rode their little ponies, smiling at one another warmly. Apple Bloom had to ease back on her thrusts in order to ensure she didn't cum too soon. Twilight increased the pace to catch up to her. Silver and Diamond both had their tongue's dangling out their mouths, splattering drool onto the already drenched floor.

They had enjoyed each others 'company' long enough to tell when they were both about to blow. Twilight flicked her tail and Apple Bloom arched her back. The end had arrived.

Apple Bloom was first by a fraction of a second, the pressure in her inflated red tipped member finally released. Boiling hot, sticky seed rushed into Diamond's womb, quickly filling the tiny meat bag and overflowing in a fountain that sloshed and gurgled out of the tight pink hole and torrented down to the floor. It was as if they had dug into the earth and struck white oil. The semen continued to surge from her, bloating Diamond's belly to the point where it seemed certain it would tear. Her balls twitching as rope after rope of thick apple flavoured spunk was released. Diamond loosed one final howl before flopping limp and silent in the stocks.

Twilight squeezed Silver's cheeks together, hilting herself in the filly's ass and ensuring that every drop was poured inside, not one millilitre to waste. A sperm enema. The steel grey earth ponies tummy quickly distended, hanging beneath her limp form. Twilight loved to see her new pupil cum. The site of it alone was enough to bring her to the edge. They had already broken several new mares in together and every time was a new adventure into depravity. As her balls finally emptied she grinned.

"Ah l-l-love ya Twa..." stuttered Apple Bloom, lost in the intoxicating wash of pure bliss that accompanied her orgasm.

"I love you too," replied Twilight, checking Silver's pulse just to make sure that she was still alive. The muscle relaxant hadn't compromised her heart and lungs at least.

They both remained inside their victim's for a solid minute, letting the feeling subside. Occasionally twitching and loosing an aftershock of squirts that quickly died down.

They pulled free at the same time, both of their new cumdumpsters unloading a spurt of white fluid from their respective holes.

"Twahlaht... my dick's all itchy now..." said Apple Bloom, dismounting the quivering wreck that used to be Diamond Tiara.

"There must have still been some itch bane left inside her. I'm pretty itchy too. Let's go find somepony we can use to scratch our itch... I'm thinking... Fluttershy."

They trotted off merrily together, leaving the two broken filly's lying in the stocks. Twilight switched off the light as she left the room. Drowning the two in darkness.
