Ever Heard of the 'Hot Cock' Treatment?

Hidden by a large gray cloak, Rarity walked quickly beneath the Springtime Sun. The warmth it made her endure was anything but enviable, though to her mind she had no other choice.

Estrus was upon her, and this season had proven particularly harsh. For one month out of the year it could hit a mare at any time, and for a week or more leave her drowning in debilitating lust.

Some could handle it more gracefully. Others barely seemed to acknowledge it. Rarity, however, had never been granted a light touch.

Most times she could handle it on her own. Most times a few sessions with her toys, a cold shower, and spot of perfume could cover the scent of yearning bitch.

This time was not most times.

She had shut herself in the first day, and sent Sweetie Belle off to her friend's clubhouse. Rarity didn't know if her sister knew what she was going through, but Rarity did know she was a screamer in bed. She'd spent the morning, afternoon, and evening unable to do more than her barest functions, inbetween hours-long sessions of jilling herself silly, or hooking herself up to all the vibrators in her secret drawer.

None of it proved sufficient. At dawn of the second day she awoke early, no less burning with arousal, but determined to deal with it. Summer was fast approaching, and she had to prepare for the seasonal line-up, put on the finishing touches, get in contact with Sassy and Coco and various distributors. She could hardly do that if she was panting and moaning through the phone line.

So she opted for a trip to the Ponyville Spa. The Twins who ran the show there were fellow mares, and no doubt would understand her predicament, embarrassing as it might be.

In order to get there she wouldn't allow herself to be seen, so she'd searched for the heaviest, drabbest piece of cloth she had and sloppily worked it into something sufficient to keep her concealed. The task was made somewhat difficult by the sheer breadth and heft of her assets, wobbling and flopping about obscenely seemingly no matter what she did, but she managed. Heavy douses of perfume followed. When she began to choke, she knew it would serve.

Thus far, nopony seemed to recognize her. Several Ponyvillians looked at her oddly, but none went further than that. Beneath her hood she was a shadow, only white hooves, fingers, and in her opinion perfectly cute little snout poking out the threshholds.

Pushing open the Spa's door with a chime, she was glad to see the waiting room void of clients. Either the numbers were low today, or everyone was being sought to.

Aloe sat at the front desk, handling paperwork. Upon Rarity's entrance her ocean blues shot upwards. An odd smile Rarity had never seen on her before carved its way across her features. In her eyes shone something like hunger. It unnerved her, but she brushed the feeling aside as the wild imaginings of a stricken mare.

"Miss Rarity," she cooed, nostrils flaring, thick accent honeying her speech. "So good to see you alvays. Come, come! I see you are a pony in need."

On edge, Rarity chuckled. "Y-yes, haha. You don't know the half of it, darling."

She maintained her composure, but inwardly she was confused. How had it been that Aloe could recognize her?

Rarity followed the taller, slender woman in silence. She noted as always the uniform of the attendants, the twins' no different save for their cutie marks emblazoned in gold across the back and chest. It was simple, like a robe crossed with a toga, trimmed in gold, with white sandals adorning the hooves. The article left both arms, left shoulder, collarbone and cleavage, and the right thigh down to ankle exposed.

It was not a loose fit either, save the flag of cloth below the hips. Hugging a pony's form nicely, Rarity knew what the uniform was designed for - sex appeal. She couldn't begrudge them for it. Sex sold, and for that matter Aloe and Lotus came from another, far-off point in Equestria, so she had considered it might be a difference in culture.

"Here ve are! This room is very special, for clients who need the emergency treatments."

Rarity stepped inside and glanced about. It appeared no different to the usual rooms. Though, she realized, looking back she did not recognize where she had come from. It must have been a deeper part of the Spa, one she had never seen before.

"Make yourself comfortable, please please. I vill return shortly vith my dear sister to begin your session."

"Of course, thank-"

The door shut before she could say anything. "-you."

"Oh well, Rarity, no matter! Soon you will be rid of this accursed demon. I hope."

Shrugging the shawl from her body, Rarity stripped down to the essentials. A massage was best received as close to naked as possible. She kept her bra and panties on for the time being, however. If the twins asked her to remove them she would do so gladly. It wasn't as if they hadn't seen her bare breasts before, or even her slit.

Folding the clothes with her magic, she slid them into the wall cubby. Now her mind was racing with lewd thoughts again, thoughts that involved her and the twins.

She imagined them naked, for she had never seen them so. Their dress left little to the imagination, but just enough to tease and tantalize. In her aroused state it did more than that for her, moistening her undergarments further than they already were. Briefly she considered stroking herself to a quick finish before they arrived, only to relieve some of the pressure, but she decided better of it.

Hoping to get her brain off that particular track, she opted for exploring the room. Again, everything appeared as normal, until she touched the wall.

Upon contact, a shimmer of transient, illusory colors exploded across the entire room. It reminded her of a Sonic Rainboom, though relegated to purples, blues, and pinks. It came with a sensation too, a prickling buzz that lingered on her fur down to the bones for heartbeats after.

"How strange. What sort of magic is this?"

She knew that must be what it was. More to her curiosity, what was the magic meant to do? She was prepared to touch the wall again when the door clicked open, and she instinctually turned away.

"Hello, Miss Rarity! Ve return."

On a hoof, Rarity whirled. Smiling, she prepared to wave hello at the two mares.

Her hand fell halfway short.

They were naked. Both of them. However, this was not what caught her attention. Beyond their trim, waifish, willwy bodies. More than their pert and perky breasts, capped with succulent nipples which matched their manes. Aside their kissable thighs and hips that in the context of her fantasies she might have loved to squeeze so fondly.

No, save all that, what made her jaw drop and pupils shrink...

...were their cocks.

They mirrored one another, like much else with the twins' bodies. Both shafts were erect, pointing skywards at an angle, each capable of reaching their lips and each thick as a shot glass. The flares especially terrified her, not just due to their girth but the thick, drooling fuckslime that issued forth from them. Their sheaths and balls matched their respective pelt colors, albeit a few shades darker, but the lancing lengths were bright as sin, pastel slabs of pink and blue cockmeat.

Those pendulous danglers proved no less impressive - or terrifying. Halfway down their thighs the sacks hung low, pulled by the gravid weight of orange-sized orbs. Around them hovered a fog of musk, behind which Rarity saw dripping perspiration.

"W-w-w-wha-"

Rarity stammered like an idiot. Shaking, she took a step back, putting distance between her and the sisters.

For the second time Rarity saw Aloe, though it felt like the first. Comprehension dawned as she could no longer deny the yawning hunger in her eyes, nor the jaw-splitting grin on her face. It inspired in Rarity a blind, animal terror that told her to run - run and never look back.

Lotus scared her less. She looked almost compassionate, her blues softer and understanding. But in them was the hunger too, no less strong, just restrained.

"What is the meaning of this?" she shrieked, perhaps louder than she'd meant to. Her own ears wilted, pinning flat to her skull. "This... this... obscenity!"

Her arm flailed, gesturing wildly at the pair. Neither flinched, nor were dissuaded in any way.

They'd dealt with reactions like hers before.

"Simply a matter of procedure," Lotus answered.

Aloe finished for her. "You have entered with heat, no? Ve vill take care of this. Trust me, you vill thank us after." Licking her lips, she used one manicured hand to stroke from base to tip, the other her sister's.

Rarity blanched. "No, this is indecent. This is... disgusting! You cannot just walk in on a lady, naked as the day you were born, and offer to fuck her! Have you mares any standards at all? Any decency within you?"

"It is not an offer," Aloe corrected. She took a step forward, angling her prick at Rarity. "It is a promise."

"No," she growled. A fiery look overtook her sapphire eyes, and she aimed her horn at the approaching dickmare. "I will not allow you, and when I escape I will report you to the proper authorities. I do not care how good a masseuse you criminals are, either of you."

Aloe remained unperturbed. Her sister meanwhile observe with passive interest, but she was slave to her lusts in a different way. Her shaft, possessing a will of its own, splashed a handful's worth of pre-cream between her hooves.

Rarity prepared to summon a spell. Her horn glowed bright azure, brighter, brighter, so bright it hurt her eyes.

And fizzled out.

"What?"

Aloe cocked a brow. "You think ve have not dealt vith this before? Silly silly," she scolded, clucked her tongue and shook her head. To Rarity's growing horror, the spa twin explained her predicament. "This room has enchantment. Sound will not come out, and the door vill only open for myself and Lotus."

While Rarity's attention remained locked on Aloe, her sister snuck from the side and seized her elbows. Rarity fought in vain against superior earth pony strength as Aloe closed in, then slapped her she-rod against Rarity's belly, her watermelon tits.

"G-get off me you ruffians! Just you wait until somepony hears about this!"

Aloe giggled as Rarity struggled on, much to the pink mare's delight. "You may continue to resist," she crooned. "I like the vones that fight."

Aloe grabbed Rarity's chest. Her nails, filed to fine peaks and painted the sky blue of her sister, her mane, tail, and other bits, sank sharply into the vast white titflesh. Rarity cried out at the pain, making Aloe's cock throb and splat fresh cumfroth on her muzzle.

The stench settled into Rarity's lungs. Her eyes watered, nose wrinkling at the pungent aroma of virile cock. She hated utterly how wet it made her pussy. Damn her terrible heat, and the disgusting things it made her body want, no matter how much she herself rejected it.

Lotus, behind her, whispered. "Just relax. Ve only vant to help you."

"H-help me? You think this is helping me? Your pervert of a sister is hurting me, and I have given you my very explicit lack of desire!"

Lotus gave a pout, clicking her tongue as a disappointed mother might to her child. "You vill understand soon, Miss Rarity. You came in because you vished to be help vith your heat, am I incorrect about this?"

"N-... no."

Aloe laughed. "That is all ve are here to solve, darling. Be a proper bitch and you vill be rewarded vith our bastard foals."

What?"

The word pealed out as a shrill screech. "You- no, you can't possibly! M-m-my career, my reputation! I'm the Element of Generosity, how can I defend Equestria if I'm traipsing around with some parasite in my belly? A-and for that matter, what do you mean bastard? I am no married woman!"

"It is simple, dear beloved Rarity. Ve are married to each other!"

Before Rarity could even begin to think of a response to that, to comprehend the dark, dgenerate depravity that ran deep between these two, they kissed. Right in front of her. They, sisters, kissed, full prench style with suckling tongue and biting lips. Then, as they pulled away panting, Aloe ripped Rarity's bra shear from the fur, revealing her tremendous alabaster globes to the twins with a profaned jiggle.

Her cheeks flushed from white to a vivid crimson. Below, much to her dismay, the swollen lips of her engorged marshmellow muff throbbed, pained and needful.

Gods be good, what was she becoming? Estrus was degenerating her into some lewd, twisted beast of rank perversion.

She'd end up no better than these incestuous molesters. And worse, perhaps they'd been correct from the start. Once they'd finished violating her most sacred of places and dumped their unholy spawn inside her, she'd learn to love it.

She didn't want to.

But clearly, neither Aloe nor Lotus, in spite of how much more gentle she was than her pink counterpart, gave a shit what she wanted. They were going to take her, ravage her body in ways she'd never in her wildest nightmares could have imagined.

As she felt herself be hauled into the air, and looked down beyond her swollen, sweater-straining meatjugs to see them ready for penetration, she renewed her struggles. She kept her thighs clamped firmly shut, clenching her teeth with such force they threatened to shatter.

Every step of the way, she'd fight until she could fight no more. That was the least she could do, to survive as long as possible with her dignity intact. They'd have to rip the self-respect out of her chest, bloody and beating.

"Oh sister my lovely," Aloe sang. How twisted this all was, a voice Rarity once thought so sweet, turned wicked and cruel. "Vould you aid me vith our unruly client?"

:For you, light of my life? Vithout question."

Smiling, Lotus moved her grip from Rarity's arms to her legs.

Rarity tried freeing herself once more, and managed to elbow Lotus in the face before Aloe stopped her.

So instead, as tight as possible, Rarity clamped her thighs shut.

The attempt was purely symbolic. Her, a flimsy unicorn dame, could do nothing against the combined might of two earth pony mares.

Rarity whimpered as Lotus pried her legs apart. Spreading them wide to present her angry, pink, puffy pussy, Aloe giggled.

"And you say you do not need our help, Miss Rarity. Look at this thing, sister. It is as pink as my fur!"

Lotus said nothing, but nodded, and hooked her arms under the meat of Rarity's fat thighs.

"I vill go in first, to make it easier on her," said Lotus. "Do not vorry, Rarity. I vill go slow, so you may adjust to our size."

Aloe offered no protest, but frowned, prick throbbing in erratic rhythm. Rarity could at least pull some satisfaction knowing how frustrated she must be, forced to wait for her turn at assault.

"I vould recommend taking a deep breath," Lotus offered.

Rarity did as instructed, and closed her eyes. She hoped, without sight, the fear at the moment of penetration would be lesser.

In the end, it made little difference.

Rarity keened. "F-f-f-fuck, i-i-it's too big!"

Biting her lip, breaking skin, rivers ran down her cheeks in salty rivulets. They brought with them the black stains of her mascara.

"You vill adjust soon, do not vorry. They all do."

Lotus' tone was kind, reassuring. She was still violating her, but her offered sympathies were all Rarity could cling to.

Aloe was not quite so friendly. While her sister worked on slowly pushing herself into Rarity's spasming quim, she sneered and snorted dismissively. "They are all sluts, sister. She is no different. Fuck her as she is meant to be so I may have my turn vith her."

Lotus tut-tutted, unhooking her arm to waggle a finger at the other shemare as though scolding an unruly child. "Be patient, love. When my cock has molded her insides she vill be a perfect fit for you."

This did not please Aloe, but no argument was broached. She huffed, and contented herself by grinding her fuckstick against Rarity's outer folds. Pre would occasionally spill out her cumslit, and smear itself against Rarity's prominent, throbbing clitoris, drawing unwanted gasps of pleasure from her throat.

"Eager already? From your upper lips you say you do not vant this, but your lower lips disagree!" She laughed, a bird-like, tinkling sound.

Rarity would not entertain her. But as Aloe had pointed out, she needn't utter a word for her body to speak volumes. Her nipples, purple as her hair, were stiff, turgid peaks that begged to be played with. The temptation proved sufficient for Aloe to take her own liberties, savagely biting her tender breastflesh, or worse the terribly sensitive teats.

It made her writhe and squirm. Mewls of pain were interspersed with those of pleasure, which encouraged Aloe's attentions. Rarity would not be surprised if afterwards her chesty mounds were riddled with swollen red hickeys. Yet also, with Lotus gradually feeding inch upon meaty, throbbing, vein-ridged inch into her too-tight twat, Aloe's abuse did at least offer her something else to focus on.

Once Rarity had been lowered to the medial ring, Lotus dropped her the rest of the way. Her cow tits were sent bouncing, curves rippling.

She couldn't stop the moan that clawed its way from her depths. She hated how good Lotus' cock felt. She didn't want this, she didn't, but her made-to-pound pussy kept chanting yes, yes, yes!

Aloe cooed, prodding the extra fat on her tummy. "Aw, she is so cute vhen she jiggles like that."

To Rarity's immense, mortified shame, Aloe pinched a doughy roll of marshmellow meat between her fingers and wiggled it. It was one of her greatest shames that she, despite the image of perfection she elsewise tried to maintain, could not quite get her belly down.

It wasn't her fault, she told herself. Anypony would get some padding if they had icecream shovelling, soap binging, sob-inducing nighttime marathons.

"S-s-stop thaaat!" she whined, further squirming in her restraints. But Lotus was to her back, superior earth pony strength putting a firm boundary between her and freedom. There was nothing she could do.

"Quit tormenting the poor thing, Aloe. Besides, vhy toy vith her when you could use these?"

Grinning, Lotus released and left her embarrassingly impaled on the pulsating, pink cock. Her freed hands groped either breast from behind, using the nipples to waggle and slap them about. While Rarity burned with shame at the treatment, Lotus hauled her back into fucking position and began to bounce.

"Vhat a vonderful idea sister!"

As Lotus shunted her hips upward, clapping flesh to flesh and balls to ass, Aloe steadied Rarity's gravid, jumping mammaries. Lotus' motions were careful and considered, enough to cause noticeable jostling but always careful not to hurt her. So it wasn't difficult then for Aloe to slip her colorful blue slamshaft into the realm of yawning, white-furred cleavage, and begin pumping away.

Rarity tried turning her head from the flare, but Aloe was insistent. She wanted her to feel the shame. Wherever her face turned, she angled her hips so the stallionhood's tip pressed out between her jugs, either spewing pre-cum onto her face or smacking her with its blunt, built for gaping cockhead.

After a while, Rarity gave up the effort, and allowed Aloe to grind her slime-filmed prick against her face.

"I... am about to cum soon," Lotus warned. Rarity could've picked up on the fact without the announcement. Her thrusts were becoming less methodical, not as considered. The result for Rarity was a more thorough cunt pummeling, which meant for her more pleasure she did not desire.

Twittering, Aloe yanked her prick free of Rarity's cleavagepussy. She crouched into a wide-legged squat, her own balls grazing and pooling against the floor, while she took Lotus' into her hands. She kneaded them, rolled them between her deft fingers, and between kisses and long slurps crooned, "Fill this uppity bitch up. Pump her ovaries vith seed until she is always pregnant vith your foals. Just make sure to leave me the other half!"

Her sister's ministrations, and filthy words pushed Lotus over the edge. Crying out she slammed Rarity onto the base of her meat, eliciting a sharp yelp, and shot tacky tidal waves of nutslop into Rarity's waiting, fertile womb. She was in heat as well, so pregnancy was absolutely guaranteed.

Standing up, Aloe moved beside Lotus to take her place. The gentler of the spa mares caught her breath for a moment, then extracted her softening pole from the creampie that was Rarity's love tunnel.

Shivering, gut hefty with shespunk, Rarity feared. She could grasp onto sanity by its edges with Lotus, but with Aloe? She would not be so kind.

Wordlessly, after exchanging a sloppy, tonguefucking kiss, Aloe replaced her sibling. Rarity's belly began to deflate, excess slag pouring out her folds like batter, but Aloe soon made her way of lovemaking clear. Without so much as a heads up she hilted her entire length inside to the sound of a profane SQWUILCKH, and plugged her up so no more could escape.

"I may not have as much patience as you, my darling," she said, gazing lustily into Lotus' eyes. "But the vait is vorth it vhen I feel your cum around my cock."

Giggling to themselves in only the way starcrossed lovers could, Aloe shifted her position. Rather than pinning her legs apart she wrapped her arms around her midsection, squishing her sloshy stomach and massaging her own cock through the skin.

Rarity took in a deep breath, because she knew she would need it. Lotus meanwhile stepped into frame, taking her spot where Aloe previously occupied.

The breath, as it turned out, didn't matter a damn bit. Aloe instantly jackhammered her pussy, thrusting with all her speed and earth pony might behind it.

Rarity screamed. If the walls of this dreaded room were not magically soundproofed, the sound would surely stretch to the Everfree and beyond.

Hot tears rolled with free abandon, Her mouth twisted in a series of meaningless forms, her features contorted in ways no mare in their right mind would wish to be seen by another.

Every meaty inch of her well-endowed form shook. Several times, her breasts came high enough to whap her face. The pain hardly registered. There was too much sensation between her legs, the carnal canal that the twins had stolen for their own.

She was claimed. She was a marked bitch. If she did somehow get out of this ordeal with her mind intact, she doubted the most powerfull spell in all of the Royal Archives could manage to scrub the taint away, much less the clinging sheseed basting her eggs.

Rarity, Element of Generosity, premiere designer, fabulous fashionista, could now add 'Spa Twins' Pocketpussy' to her list of accalades.

And they made sure to hammer the point home. While her conscious, material world had been swallowed up by the brain-numbing sensations of Aloe's mighty fucking, they sought to rebuild her internal one.

One voice behind her, snide and jeering. The other in front of her, soft and soothing. Together, they attacked her mind from two fronts.

She was a whore.

She was in heat.

She wanted this.

She needed help.

She was a whore who needed help. She was in heat and wanted this. She was made to take marecock. She loved taking marecock. Marecock was the best solution for treating her problems. Marecock was the only way she could focus on her life again.

It all blurred together, noises in a soup. The soup was her mind, and it swirled inside her skull, spilling out her gushing gash in waves. Climax upon climax electrified her body, and soon the pleasure overwhelmed whatever previous emotions she'd felt about this.

This is where she belonged. She had marecock inside her, and it felt so fucking right.

Rarity spent an eternity in that bliss. Her makeup ran. Her tongue drooled and flopped. Her tits and ass bounced and plapped with the same fervor as a bouncing castle.

She didn't know how long she stayed like that, but she knew one thing for sure.

They had fixed her.

She needed it. She was a slut. She was in heat, but not anymore. Because they were so kind and helpful and ruined her brains and got rid of that nasty heat so she could function again.

Function for what purpose?

She... she wasn't so sure about that one anymore.

But she knew what her new function was. She was a whorse - their whorse. They were so kind and helpful to make her realize that. She loved them. Maybe if she was really lucky they'd consider keeping her around - as a pet of course, she didn't deserve the honor of being their wife.

Aloe was the one who told her what her job was after she hit the floor, bloated and barely able to crawl. But she didn't need to move for the task Mistress Aloe had given her, in the form of her half-flaccid, cum-streaked spunkhose.

"Clean us up, whore," she ordered, and Rarity obeyed without a second thought. The flavor of her own mixed cunt juices and the twins' syrup-sticky, throat-coating ballgoo was the best thing she'd ever tasted. If she weren't shattered already, she'd have become addicted at the first gunky drop.

Once her and Lotus' dirtied cocks were cleaned, iridescent in the light, Rarity went totally limp.

On instinct she reached for her swollen gut, a round beachball of a thing, swirling and sloshing with powerful maresperm. Her hands, weak and trembling, pressed into the soft, pliable mass.

She glowed, happy as a clam. She was pregnant for sure, the broodbitch for two naughty shemale lesbian sisters.

Their foals would be so pretty.

"Ve vill be back tonight," said Lotus. Before she departed she crouched to kiss her on the lips.

And Rarity smiled.
