Masked Matterhorn vs. High Heels I

"Yes, I'm positive that I can handle myself just fine! Enjoy your vacation, everypony!" Twilight waved goodbye to her friends and then had to handle everything alone for an entire week. "Alright then, no pressure, everything will be just peachy!"

Telephone ringing!

"Oh, it's from the commissioner? I'd better get that right away" Twilight picked up the phone and answered. "Hello, you have reached the Power Ponies HQ; this is Masked Matterhorn; what seems to be the problem, Commissioner?"

"You're there? Oh, thank goodness one of you picked up."

"Well... I am the only one here right now... um, sir."

"Where's the rest of your team?"

"Currently enjoying vacation, as of right now. And somepony had to watch over the place."

"Well, I suppose one is better than none. We've got an emergency: the Maretropolis Scientific Research and Development Facility is being robbed! In their Laboratories, oddly enough. This robber isn't interested in stealing any money, just some experimental documents and a super-powered formula; the one that can make that Saddle Rager power pony bulk up! I don't think I need to explain how dangerous it would be if they learned how to weaponize that potion!"

"Crap, you're absolutely right, Commissioner. I'm on my way down there!" Twilight hung up the phone and got ready to go! "Hold down the fort for me, Spike. I'll be right back!"

"Alright then, Twilight. Be careful out there!"

"I will, thanks!"


At the entrance to the Science Facility: "Alright, I've made it! Whoever decided to rob this place had picked the best time to do so, impeccably so." Twilight made her way into the laboratory and down its corridors. "Ok, that thief should still be around here, somewhere!"

Twilight looked through every room, checking where the intruder might have chosen as a hiding spot. Suddenly, her ears perked up at the sound of glass being broken. "Aha! That'll lead me right to the criminal. Whoever this is sure is sloppy; that will cost them!"

"Hahaha! I've got it; this potion is all mine! Ooh, baby, it's been such a long time since my parole and then Having my powers taken from me. But that's okay; momma's got them back!" The intruder, holding the stolen potion, had heard the large double door behind her bursting open, revealing the form of the super-heroine clad in purple.

"Stop right where you're; whoever you're, you're under arrest! Come quietly and peacefully; I promise you this'll be over quickly, and you'll be out in no time!" Twilight saw this intruder, getting a good look at her! She was dressed rather revealing; this caused Matterhorn to lightly blush at seeing most of her uncovered assets; the exposed parts were undoubtedly noticeable, that was for sure.

"And just who're you supposed to be?" The mare being confronted raised an eyebrow, clearly unimpressed and irritated with this intrusion into her plans.

"The one that's going to kick your ass if you don't surrender now! Masked Matterhorn, Power Ponies!"

"I suppose I should introduce myself too, lest I be rude! Name's High Heels. I currently have no quarrel with you, so stay out of my way if you know what's good for you!"

"You don't scare me; I'll have you know! Unfortunately for you, I must do my job, so surrender now or be taken down by force; it's your choice."

"Ooh-oh-oh, aren't we just intimidating? Wouldn't it be a shame if all that confidence were suddenly snuffed out from you?"

"You're about to find out if you press me!"

"I don't have time for this! I'm going to deal with you right here, right now! Cheers, love!" High Heel then tilted her head back and downed every drop of the potion.

"Wait! No, don't drink that!" Twilight reached out to try to stop her, but it was too late; she drank it, then grinned evilly at Twilight!

"Hah! Imagine if I were able to dominate and humiliate the ringleader of the Power Ponies single-handedly! Why I'd be the talk of the underground for ages! Maybe even earn my spot in their hierarchy; they'd be so jealous of me!"

"Man, do you ever shut up? I mean, really?"

"That sounds like a splendid idea to me! First, I'll crush your body, then your mind, and then your spirit! Yes, this room appears to be big enough for my powers to be unfettered. Perfect!"

"Quit your rambling and just give up already!"

"Alright then, here's how this'll work: Since I've already drunk the formula that you needed to retrieve successfully. I'll simply give you the opportunity to apprehend me and bring me to justice! But not without a fight!"

"Sighs Do we seriously need to fight? Fine then!"

"Come at me if you dare!"

"Fine! But remember this, High Heels, you asked for this!" Twilight began charging up her horn, selecting the ice beam attack. "Take this!" The beam was fired out, heading towards High Heels. She just stood there, smirking!

"Really, An ice beam? That's the best you can do? Here I come, Matterhorn!"

"Bring it on!" High Heels did just that, the ice hit the floor, creating a slippery field of effect, but it didn't work; High Heels was skating across the ice and gaining.

"Say Matterhorn, thanks for the speed boost; I appreciate it!" High Heels was right in front of Matterhorn, holding up a bottle of strange spraying liquid; it was slightly bubbling. Matterhorn recognized this compound; this was what Mane-Iac used to take their powers away!

"Oh crap!" High Heels had sprayed the liquid out at her face, forcing her to gag at the strong chemical smell it gave off.

"I'm sure you're very familiar with this stuff, used to strip you of your powers. The prototype of this compound was what Mane-Iac had used before, now tweaked, of course!"

"N-Not that stuff! You bitch!"

"Now you've got no choice but to play by my rules! This'll be fun; just you wait!"

"I'm j-just quivering my boots in anticipation!"

"Now see, that's the spirit! You now must rely on your physical strength, endurance, and agility. With no superpowers to aid you."

"W-Why you.."

"As for me, however, I'm not bound by anything!"

"G-Good for you!"

"Isn't it, though? Well, I suppose I don't need to wear these anymore; tailors for my garments are too expensive!"

"W-What the hell... y-you're stripping!?!" Twilight's face turned sheet white for short brevity, her brain still trying to process this series of events unfolding before her!

"Sure am! I see you peaking! You know, looking isn't a crime!" Was she seriously giving Twilight a lecherous glare? She was planning something terrible.

"I'll still bring you down, High Heels. With or without superpowers!" Twilight then charged at High Heels, readying a strike to her face!

"Good, then come get me!" 'Excellent, she's being goaded into my hands, perfect!' High Heels just stood there, in her battle-ready pose, with her eyes firmly locked on their target!

"This one's going to hurt you, High Heels!" Twilight's fist was aimed for High Heel's face, but before it could connect, she intercepted it with a swift grab to her upper arm, holding her there and watching her try to struggle! "Augh! Let me go!"

"And why should I?"

"Grr, you will release me, High Heels, right now!"

"I repeat, why should I?"

"Because of this!" Twilight kicked her leg and struck High Heel's crotch, causing her to buckle and let Twilight go!

"Augh! Why, you little bitch! Crotch shots, really?"

"Unless you want another one, you'll give up now!"

"Now I'm pissed; you're going to regret that, Masked Matterhorn!"

"Yeah, sure I am! Crazy skank!"

"What did you just say to me?"

"Why don't you come over here and shut me up then!"

"Not a problem!" High heels then launched herself up to Twilight, knocking her over and pinning her down; she was graceful and skilled with her legs! "Don't know how to counter pins, hmm? This is going to hurt!" High Heels lifted her foot, still keeping Twilight pinned underneath her and trying to shove her foot in her face! "Here! Take this while you're under there!"

"Ugh, no! Get your smelly foot away from me; I don't want to sniff that!"

"Too bad, now sniff, bitch!" The foot made contact with Twilight's face, causing her to groan at the horrible stench of cheese invading her nostrils. "Yeah, how does that smell? Enjoy it, bitch!" High Heels just slowly rubbed and smeared her foot in deeper, proclaiming who runs the show through action, much to Twilight's disgust!

Smearing and rubbing!

"Ha, my feet on your face, how appropriate, Power Pony!" She continued to grind her foot into Twilight's face!

'Ugh, this is so nasty, on so many bucking levels. This mare is gross! Yuck, I need to get her off me before she knocks me out with her stink!' Twilight was struggling to escape from the pin that High got her in, then, to her horror, her other foot was coming in!

"It looks to me like you're a foot magnet, Matterhorn, not that I'm complaining, just a simple observation!"

'No, not the other foot; it feels like her stench is slowly sapping away my strength, not good at all!'

Smearing and rubbing!

"Sigh Looks to me like this is it for you; how disappointing. All this talk about the Power Ponies being tough, and you're beaten by my stinky feet?" High Heels had scoffed, looking at her enemy with disappointment. Suddenly, she felt her feet being pulled apart, slowly revealing Twilight's face, her sweat-matted fur, and her frazzled mane.

"Coughing Ugh! Nasty, you're so n-nasty! But I'm not throwing in the towel, not yet!"

"Then escape or be smothered in my stench, simplicity itself!" High Heels was thoroughly enjoying herself at Twilight's expense. After all, one of Twilight's most significant weaknesses is being used on her! Her nose is sensitive to pungent and foul odors, and High Heel's feet were smelly and pungent.

'Ugh, I'm going to need more strength to escape her feet, but that's risky as that'll be less than I'll have during the rest of this fight. Oh buck it, I'd rather have a sharp cut in my strength than to be subjected to this sharp stench!'

Smearing and rubbing!

"Are you still breathing down there? Good, 'cause my feet are getting sweatier now; the smell will only get better for you!" Then she felt more and more force being applied to Twilight's escape attempt! "Hmm? What's she doing down there?" Then her feet were lifted up, and she was forced off of Twilight! "Wait!?! What're you doing?"

"E-Escaping! What does it l-look like?"

"Oh no, you don't, Matterhorn!" High Heels then stomped her foot onto Twilight's chest and caused her to open her mouth and yelp in mild pain; perfect opportunity! "Here, suck on this for me, won't you?" She plunged her big toe into Twilight's mouth, causing her to recoil back in shock and disgust! "How's that taste, bitch?" Twilight was green in her cheeks!

"Mmmpth!" 'Oh god, I think I'm going to be sick! This is bad, b-but I mustn't give in, not to this sadist!'

"That's right, cry for me! This little match of ours is mine!" High Heels had further enunciated her point by shoving her other foot back in Twilight's face, effectively burying her back into her cheesy hell! There were muffled screams of anguish, then nothing! "Looks like I win this fight, Matterhorn! No surprise, really!"

She gets off Twilight and walks over to her suit to pick it up when she gets clocked in the back of her head! "Augh! What the..." She looked back at twilight, standing there, pissed and determined to win! "You faked it! Not too shabby!"

Coughing and gagging!"Ack, that awful taste is still in my mouth! I faked being knocked out, so it'll throw off your guard!"

"Well, that's pretty dirty fighting, you know!"

"So is trying to suffocate me in your nasty feet, Heels!"

"The ends justify the means, as far as I'm concerned, and as you've smelled, my tactics are most effective!"

"Yeah, I'll give you that one!"

"So, ready for a second helping?"

"No!" Twilight charged and lunged at High Heels, successfully knocking her over. But High Heels had expected this and let her do it! She rolled over, so she was on top again; then, she positioned her butt to hover in Twilight's stunned face.

"No!"

"Yes!"

"You wouldn't sit on me, would you?"

"A stupid question, don't you think?"

"Nnnoo!" Twilight screamed out as High Heels spread out her buttcheeks to reveal her twitching pucker to Twilight. Why was it twitching through? Oh crap!

Rumbling and gurgling!

"I'm sure you could guess what's going to happen now!"

"P-Please don't!"

"Ignition in... three... two... one... zero!"

BRRPPTTHH!

The horrible stench of manure and digested veggies was burning into Twilight's sense of smell. Naturally, she was moaning in agony, especially when High Heel slowly smeared her sweaty flanks into Twilight's face! "Enjoying yourself, I bet!"

Smearing and rubbing!

"Maybe, if you're a submissive pony, I'll take you back to Mane-Iac's Warehouse so you can greet her butt too, and her feet, of course! If you think I can be a stinky pony, you haven't had a sample from Mane-Iac! Because pee yew, that mare knows how to fumigate a room!" This thought terrified Twilight to no end! Many fates could easily have befallen a Power Pony, but death by atrocious stench was definitely not one she was expecting, nor that she ever wanted!

"I... I-'ll beat you and send you to j-justice, High Heels! Ptoo, nasty. And w-when I do..." That was all she could say before High Heel's large ass smothered her; her protests went back into repressed muffles of agony, and the stench of High Heel's fart was still clinging to both her face and in her butt!

"Just shut up already and sniff! You're not in much of a position to threaten me, now, are you?" High Heels snidely looked back at her big butt as it pressed down over Twilight's disgruntled face. "Just be a good pony and take a deep breath for me; these next few brewing are going to be even better!"

"Mmmpth!" ' I highly doubt that, you disgusting skank!'

Rumbling and gurgling!

FRRPPTTHH!

"Wait! I can do better than this; hold on!"

BRRTT! FRRTT! PRRTT! BRRTT! PRRTT! PPPPPSSSS!

"Woah there, High, bad girl, stinky girl! That barrage took some extra effort; how're you holding up?" She was massaging her flanks while moaning sensually.

"Mmmmpth!" 'I-I can't Breathe; her farts have flooded my lungs! Why? Why does this mare have to be so gross? If what she says about Mane-Iac is true, I need to get out of here! It's nasty, but I've got no choice!' Twilight manages to bite down on High Heel's ass. This caused the flatulent mare to gasp at the surprise bold move! That surprise had turned to a cry of pain, then anger as she got off Twilight's face, giving the Alicorn some fresher air to breathe.

"You dare? You dare bite my butt?!" High Heels was less than amused now, looking at Twilight with great scorn. "I'll make you cry now; I'll make you suffer; I'll make you scream my name!" High Heels had stepped back and glared at Twilight before taking a deep breath, then releasing a war cry! "Hhhyaaa!" High heels began to grow into a titan, gaining feet, weight, and mass to her body. She was at least ten times bigger than Twilight; her breasts, belly, and butt were mountain-sized for the poor Alicorn.

Looking up with shock and fright "Woah... holy hay... I-I need to get out of here!"

"Hello there, little Power Pony! From my current perspective, you look pretty small down there, small and pathetic, like a bug! She lifted her giant foot, wiggling its toes as she did so. "You know what I do to bugs? I squish them! Hahaha!"

"N-no! y-you've got to be bucking kidding me! I don't want to get squished underneath your nasty feet!" Twilight had to pinch her nose at the powerful odor her feet gave off, she hadn't even stepped on her yet, and already Twilight felt like she was going to break down and cry!

"Well, too bad, little bug! Because here I come!" She lowered her foot; its sharp stench was becoming more and more pronounced the closer her foot got to Twilight! The stench was so strong at her current size that it was amplified tenfold. Twilight was scared now; she didn't want to be smothered in this atrocious stench! "Incoming stomp! Buhahaha!"

BOOM!

High Heel's foot landed on poor Twilight, smearing her face into the sweaty sole of her foot. Twilight couldn't even think straight anymore. "Ha! Your new name should be Mashed Matterhorn! Cause that's what you look like under my foot!" Twilight was groaning in sensual agony; this was a cheesy hell that she was plunged into with no parachute!

Smearing and rubbing!

"Mmmpthahh!" 'Oh my... this is absolutely horrible! So this was what she meant when she said she would break me? Help... somepony... please!'

Smearing and rubbing!

"Ahh~ :heart: You feel so good as my little foot cushion, Matterhorn. Are you sure you don't want to reconsider a career change? Time to grind my superiority into you, to let you know who's the mistress!"

Smearing and rubbing!

"Mmmpthahh!" 'It...stinks in here! This is so bad; I don't want this! Why did I ever agree to my friends going on vacation without me? Stupid Twilight, you're being stupid! I... need to get out of here... before I pass out!'

Smearing and rubbing!

"Ooh, that's nice, you feel so bucking good under there! Struggle for me!"

Smearing and rubbing!

"Ok, I think that's enough foot for you!" High Heel lifted her foot from Twilight's body to see her limbs twitching, dried tears down her cheeks, and weakened groans of anguish. "How was that for your first lesson in submission? Tell me!"

Coughing and gagging! "B-bad! I... hate you so much right now!"

"Is that so? Good! Because I get to have some more fun with you now!" High Heels was now standing over Twilight, her giant size completely dwarfing her small stature. Due to being down to her foot level, Twilight was still trapped in what was left of her nasty foot stench, forcing her to cough and gag still.

"Hmm... I know where I can put you next! This'll be so much fun!" She reached down to pick up Twilight and lifted her to her crotch; Twilight grimaced, knowing fully well what High was planning.

"Y-You can't be s-serious, High? No, you're not going to shove me in there of all places!"

"And just what do you plan to do to stop me? You're too small to be considered any more of a threat to me!" High then used the hand that wasn't holding onto Twilight to part her juicy folds. It looked like a hungry maw waiting for its prey!

"My pussy is hungry, Matterhorn; time to feed it!" Then High pushed Twilight into her folds, but Twilight was trying to hold them back; this amused High for obvious reasons! "Oh? So you wish to fight it, huh? Then, by all means, I won't stop you!"

Smearing and rubbing!

High then slowly but purposefully smeared Twilight's tortured body into her snatch, relishing in her cries of protest! "How's this, then, the scent of a powerful, sexy mare?"

Smearing and rubbing!

"Aahh! S-Stop this... please" The more High rubbed Twilight in, the weaker her resolve was; she was a professional at what she did; Twilight knew that for a fact. The clammy feeling of her moist dripping crotch and its harsh musky odor was eating away at her resistance.

Smearing and rubbing!

"Hah! That feels damn good! You're a much better sex toy than a superhero if only you'd realize this truth!" High heels then began to push Twilight deeper into her snatch; her tiny body was now halfway in.

Smearing and rubbing!

"G-Gah! S-stop this... please!" Twilight was giving all she had into her struggle! Sadly, it wasn't enough to escape. If anything, it only pulled her in deeper.

Smearing and rubbing!

"Hah! Ahh~:heart: Yeah, keep it coming, Matterhorn! You're almost there!"

Smearing and rubbing!

"N-No! Noo-mmpth!" Now she was buried entirely into High Heel's snatch. The thick, muscly walls of her vagina were closing in on her, pressing into her in all directions; it was the slimiest massage Twilight wished she had ever had.

"N-Now, just s-stay in there for me, Matterhorn! Let my hungry pussy snack on your strength!" Twilight screamed into High's musky snatch, punching and kicking at her walls to try to escape. But sadly, this only caused indentations of her hands, feet, and terrified face to be poking out from her fleshy and net-like prison. "I'll slowly savor you, Matterhorn! Then we'll have more playtime together, isn't that great?"

Squirming and struggling!

"Mmmpthh!" 'No, that doesn't sound great, you filthy skank! Let me out of here! It smells bad in here! Augh!'

Squirming and struggling!

"Yes! Keep squirming in there! I'm going to cum if you do! Ahhh~:heart:!"

Squirming and struggling!

"Mmmpthh!" 'Gotta try something different then! Her snatch is starting to fill up with her release... Oh no!'

Squirming and struggling!

"You're pushing your luck in there, Matterhorn. Say no more; I understand you completely; you secretly love it in there, don't you?"

Squirming and struggling!

"Mmmpthh!" 'Why the buck would I ever like this? It's so gross and smelly in here! I will never give in to you, no matter how hard you try!'

Squirming and struggling!

"Is that a challenge, Matterhorn? Because I do love a good challenge!"

High Heel then began to moan and pant; her moist pussy pushed Twilight tighter, like a musky and damp, muscly hug. Then she came, and her pussy spat out Twilight, dazed and traumatized as she lay sprawled over the floor. "I-I think I m-may have swallowed some of it, y-you nasty bitch! I'll never let you take me to Mane-Iac, ever."

"Oh dear, you're ever so frightening now that you've been used as my sex toy! So then, you feeling the draining effects then?"

"S-Shut up!"

"It's a simple yes or no question, Matterhorn: Do you surrender or not?"

"N-Never!"

I was hoping that you'd say that!"

'Oh no, what's she planning to do now? I don't want any more of this... too weakened to run away... this is n-not fair!' Then, to Twilight's absolute horror, High turned around to show off her ass! It was the biggest and most terrifying thing Twilight wished she never saw... ever. And she was twerking it, up and down.

The fat or her ass was jiggling with reckless abandon, ready to plunge and crush the poor Alicorn underneath. Twilight's eyes have shrunken to pinpricks, her head sweaty, her mane frazzled, and her heartbeat racing. "No!"

"Oh yes, Matterhorn! Yes indeed!" High was licking her lips in lustful anticipation, awaiting that perfect moment when Twilight gets flattened and smothered into her powerful and gassy flanks.

"P-Please no..."

"Oh! Keep begging like that for me; it's so bucking arousing!" Her flanks were falling onto Twilight's body; Twilight's life had flashed before her eyes!

"NNOOO!" Twilight reached her arms out in despair, bracing for the inevitable butt torture she was to endure next!

BOOOM!

High Heel's ass had landed on Twilight's body, burying her underneath hundreds of pounds of toxic flank fat, slowly squishing outwards like supple and pliable dough, the smell getting increasingly worse the more she stayed under there. "Oh yeah, baby! That's more like it, right where you belong too!"

'P-Please... somepony... h-help me!'

Smearing and rubbing!

High heel's gigantic ass was unmerciful; she was going to break poor Twilight under her in every conceivable way. Twilight was suffering, big time! 'Oh god, why does her ass smell so horrible? T-This mare is cruel, beyond anything I have ever experienced in my entire life! P-Please... m-make it stop, somepony!'

Bouncing and grinding!

FRRRPTTHH!!!

"Ahh... that one felt like a proper ripper; you're a very nice torture toy, Matterhorn. I'll still very slowly savor this time we've got together!"

Tiny muffled screaming and crying!

"Oh hush down there, you bucking love it; I know the truth!"

BBFFPTTHH!!!

"I'm just gonna keep peppering you with my sexy farts until you're too weak to escape!" High Heel then stood up; Twilight was wedged in deep; you couldn't even see any of her body anymore, save for some of her mane and tail still poking out from between highs mighty ass. "Aww! you look so cute, stuck in there like that; time to rough you up even more!"

Tortured groans of protest!

Twilight was squirming and struggling, anything to try to escape from her skunky prison. High Heels looked back at her butt; then she began twerking it slowly up and down, like wobbling jello. 'Oh Celestia above, what is this bitch doing now! Is she... bouncing me in her ass cheeks? Oh no...'

Whining and struggling!

"Time to make good on my word, Matterhorn, take some more deep breaths for me..."

BRRTT! FRRTT! PRRTT! BRRTT! PRRTT! PPPPPSSSS!

"Oh yeah... nice and toxic, just how I like them to be! It's only going to get smellier and sexier in there!"

Sobbing and struggling!

'This is getting way too much for me... i-it b-burns my nose... Her horrible farts are burning through my sense of smell... I-I need h-help, please...'

Twerking and bouncing her butt!

High Heel was twerking and bouncing her asscheeks as she hummed an upbeat tune to herself. Peppering Twilight with her vile farts in between hums, relishing in her muffled cries and screams of anguish. "Hey there, Matterhorn, Why don't you do me a favor and start kissing inside my butt?"

'What the buck!? There's no way I will do that for you; it's already bad enough under here, m-mercy... it's t-too much under here...' Twilight was nearing unconsciousness now; High Heel's ass was a deadly weapon imaginable.

"Maybe you'll love it inside my ass instead? That can be arranged, you know." High Heel's asshole began to open slowly, and a small plume of the vile stench poured out all over Twilight's shuddering body.

'P-Please... not in there... I'm begging you... I-I I'll even surrender anything but this.' Twilight then felt the slick and rubbery anal walls closing in on her legs, slowly pulling her into her smelly demise. The stench has only worsened now that high's horrible asshole was eating Twilight. Her butt snacked on the poor Alicorn as if she were a tasty treat.

"Oh yes, Matterhorn, that's where you'll be taking your sweet little nap as I travel to Mane-Iac's Warehouse. It's pointless to fight me at this point; you might as well just let it happen." The ponut was swallowing Twilight's body up to her knees, then to her thighs, and then to her waist.

Her butt stench was incredibly concentrated now; it was beginning to make her feel light-headed and dizzy. "Now you'll have all the time in the world to kiss the insides of your superior's ass! Don't be shy, be a brave little mare!"

'N-No... please no! N-Not like this... I don't want to be defeated and humiliated like this. I n-need help... no help is coming for me...' Twilight was screaming and crying; High's gigantic asscheeks were muffling her cries. She had no choice but to let this torture continue; she couldn't fight it anymore; High Heel had well and indeed won.

BBBRPPTTHH!!!

"Whoops, let that one slip, didn't I? Well, it's already in your nose, so whiff it up." The puckered anus was already up to Twilight's upper chest and slowly inching its way up to her neck. Twilight began to use her hands to push down into the spongy anal rim to try to pull herself out of High's toxic butt in a last-ditch effort.

Sadly, as the stench got evermore stronger, Twilight began to slowly lose more and more strength to keep the fight going. "Ooh... You feel wonderful there; you're momma's little butt plug, aren't you? Yes, you're."

'N-No... l-losing my... s-strength, n-not good at all... i-it's hopeless... e-evil has won.' Twilight was ready to give up everything now; she couldn't take much more of High's toxic ass. The anal rim had reached Twilight's chin now and slowly covered up her mouth.

BBBRPPTTHH!!!

"Ahh... oof, ouch, that's gotta sting in there! Just take a peaceful and smelly nap when you've had enough, ok Matterhorn?" Twilight's grip had loosened up, and she was pulled in the rest of the way, right into High Heel's smelly cave. Just as Twilight's defeated moans and groans were tapering out, her hands slipped into there as High's butthole began to close up, completely trapping Twilight into her foul rectum.

The only things left to be seen weight's terrified screams, her eyes and part of her face sinking more profoundly, and her right hand is reaching out in despair as that was also falling along with the rest of her doomed body. High Heel had sealed everything with one last fart, the biggest one she's made yet.

BBBBRRRPPFFFPPPPTTHHH!!!

"Oh my goodness, Matterhorn, you're such a good little bitch, taking all of mommy's smelly love for her." Twilight then fainted, defeated, unable to continue the fight. High Heels shrank back to normal, grunting and contorting Twilight's body to fit within the smelly and snug confines of her asscheeks. Her ass grew much bigger to compensate for Twilight's body being fitted inside.

"The best toy a mare could ever ask for!" High Heel's then slapped her massive butt containing Twilight, making it jiggle as she put her uniform back on. With a sultry sway to her hips, she gracefully made her way out of the Laboratories and over to Mane-Iac's Warehouse.
