A nightmare of epic proportions!

"Wonderful indeed! Now that i'm freed from that dream prison, I do believe that i'll start my conquest with Celestia! But i'll have to lull her somehow. I've got the perfect solution to deal with her!" Nightmare chuckled to herself as she made her way out of Luna's Bedchambers!

"Your highness! Everything's returning back to normal now! So you think that the threat of Nightmare Moon is gone for real?" Asked one of the patrolling guards looking at Luna for an answer.

'Me gone? Hah, they're going to wish I was!' Thought Nightmare as she said "I can only hope so, I'd like to think that I took care of her for good! Let's just hope it stays that way!" Said Nightmare in Luna's voice, this seemed to pacify the guard's curiosity and he continued down the hallway past Nightmare who just chuckled at their innocence. The real Luna is stuck inside of her dreams, currently in a very smelly predicament, much to Nightmare's delight.

"Sister... Can you open your door for me? It's been a while and I wanted to check up on you!" Nightmare asked while knocking on her older sister's bedroom door.

"Come in Luna!" Celestia said as Nightmare opened the door to see Celestia slowly rising out of bed! "So it seems that Nightmare has been dealt with then. You did good Luna, i'm proud of you! So now We can all focus on a brighter future!"

~ Nightmare Moon dry heaved at hearing this!

"Is something the matter Luna?" Celestia asked sensing something wrong with Luna. "You're not coming down with anything are you?" Celestia was concerned about her little sister all the time. It would have been so touching had Nightmare not hated her guts.

"No no dear sister, everything's just fine! Just trying to recover from the battle I had last night! Tis all!" Nightmare played it off as a clever ruse. Her goal was to trick Celestia. And so far, it was working.

"Well i'm sure you'll pull together just fine Lulu, you and I have made it through worse before." Celestia was convinced that Luna was really there, everything's all going according to Nightmare's plan.

'Excellent! Celestia's every bit as gullible and dense as I remember her to be! This is going to be all too easy! But how to get her under my control though? She may very well be dull, but she's anything but weak! I'll have to play my cards right if I want this to work in my favor!' Nightmare was contemplating on how she was going to deal with her older sister, poison certainly came to mind. Sadly, an alicorn's immune system is immaculately durable, not just anything will weaken it, it has to be done by a powerful magical spell, one that also suppresses the flow of magic to their horn as well. Fortunately: thousands of years of isolation can drive a tyrant to seek a vast abundance of knowledge to use at their disposal.

"Shall I call the maids to serve us some tea dear sister? I would imagine that drinking some would be great for your recovery!" Celestia was just about to open her door to signal one of them when Nightmare spoke up suddenly.

"Wait Tia, that will not be necessary, i'll go out to get one of them for us ok?" Nightmare knew exactly what to say, she laid out the bait, let's see if Celestia will buy it.

"Well... if you're sure you want to then alright, i'll be waiting for you to come back then!" Celestia went over to go sit down on her bed to wait for Luna.

'Ha! Foolish gullible sister, you're making this way too easy for me! Embarrassingly so! Oh i'll be back alright, but I scarcely believe that you'll like what I have in store for you!'

"Alright then maids, I and my sister would like to request some refreshments to her bedchambers. Some tea specifically! And if it wouldn't be too much trouble, I would also like to assist you in its preparation as well." Nightmare had brought with her a bottle of potent magic suppressing smooze, lased with poison joke for that weakening effect to be at full bloom. One drop would be more than enough to do the job that she wanted, but knowing her sister, maybe two more drops would do, just for good measure.

"Um... of course your majesty, we'd love the help too, what's that bottle you have in your hands?" The maid was curious, Nightmare's cover cannot be blown, that would be unacceptable.

"It's an expensive spiced flavoring for my sister's tea, imported from Saddle Arabia and packed full of herbal nutrition, special for her!" Hopefully they'll accept her explanation for such a strange brew.

"Well sure you can, it looks like she'll love it! You're so thoughtful your highness!" The maid had been tricked as well. As Nightmare had poured the drops into her sister's cup of tea, the maid had noticed that she never did the same for hers. "Aren't you going to have some of that too?" She asked Nightmare.

"Actually no, i'd prefer my beverage with just some cream and sugar thanks!" This one's asking too many questions for her own good, after dominating her sister, she's next!

"Well alrighty then your majesty, let's serve those drinks then!" She was rather chipper for just a simple servant, soon that'll all change for her! Nightmare's plan was almost at its fruition, once her sister is at her mercy, eternal night will finally be hers!

"Verily dear sister, the refreshments have arrived! I have helped them to make it especially good, just for you!" Nightmare said to her sister. Nightmare was convinced that her acting was working, soon she'll have Celestia completely at her mercy!

"That's very nice of you Lulu! I'm sure you've put a lot of love into it, so... shall we then?" Celestia had then gestured to the table not too far away from where they were standing. "Now without further ado, let's enjoy our tea dear sister!"

"I couldn't agree more Tia! So tell me, what was it like for you when you were stuck inside of her Nightmare?" Asked the very mare who created said nightmare who was now sitting across the table from Celestia, sipping on her tea and waiting for her to do the same.

"How do I even describe it with actual words Lulu? Dreadful, dark, lonesome, and empty! It was just awful being stuck in there. It almost makes me wonder if Nightmare ever felt the same way! Well unfortunately, she couldn't be reformed, she would have been a great friend and a good protector of Equestria too. Well maybe one day, she'll want to to turn over a new leaf, I would be willing to give her one more chance." Celestia had already drank down her cup of tea. Moments later, she began to feel strange, her head felt funny, then her horn. Finally the rest of her body had followed suit. "W-what's h-happening to me L-Luna? I d-don't feel so good!"

"You needn't worry about that dear sister, that feeling will pass!" Nightmare said as she leaned over to Celestia's stunned form and spoke into her ear. "I have a little secret to share with you dear sister! I am Nightmare moon! And funny that you mentioned how awful it was being trapped in my nightmare, which is flattering don't get me wrong. But now, it's time for me to have some fun with you." Celestia's pupils have shrunken down to pinpricks, her breath shaken, and her heartbeat racing.

"Don't give me that look, you knew that this was going to happen someday, it was only a matter of time before the rightful owner of Equestria would return." Nightmare just stared at Celestia's trembling form, she was taken aback with how well Nightmare had fooled her.

"L-Luna... No! W-what have you d-done to my sister?"

"She's currently safe, stuck inside of me. As you'll soon be too Celly!"

"D-don't call me C-Celly! I-it's Princess C-Celestia to you!"

"Not anymore it isn't, you're no longer able to cast any magic to save your own life, I lased your tea with a powerful dark magic in the form of a smooze of my own creation that'll slowly sap away all of your magic and strength. So don't try anything stupid!"

"I'll scream, I swear I will, and you'll be busted Nightmare!"

"Go ahead, scream, get their attention!"

"Help... somepony... please, your princess needs help... Anypony!" But much to Celestia's horror, nopony answered. "Why can't t-they hear me?" Celestia muttered to herself with her head tilted down.

"Maybe they would have if I hadn't taken the liberty of applying a sound-proofed magic barrier around this room. Oopsie, I let that one slip out didn't I? my bad!" Nightmare had a nefarious grin adorned over her face, she was victorious, and now it was time for her to claim her prize. "I shan't not wait any longer, it's time for our fun together my new pet!"

Nightmare's horn had lit up and she had cast an enlargement spell on her flanks, making them at least three time their original size, each cheek was about the size of a beach ball, maybe a bit bigger than that. "It's been such a long time since we've last fought like this Celestia, but now let's take a trip down memory lane shall we?" Nightmare's fur started to revert back to its black midnight color, her eyes revealed back to their nightmarish appearance. She slapped her asscheeks with her arms, Celestia was watching in mild disgust at their rippling and jiggling from the attention they're receiving. "I'll be fair about this and let you have the first move my pet. But if you fail..." Nightmare ended off that sentence with a dark chuckle.

"You wish I would fail Nightmare! Give my sister back to me! Release her from your prison!" Celestia was preparing for her first attack against Nightmare, she knew that this wouldn't be easy. One mistake could be her last against Nightmare Moon. How could Celestia forget about what happened the thousand years ago when their last fight had occurred? Her entire head was nearly suffocated into Nightmare's massive ass! With a focused glare and some slight shuddering from the bad memory, Celestia had braced herself for another bout against the sadistic queen of nightmares.

"Are you going to attack me, or should I make the first move? I can see that a thousand years of royalty has made you nice and lazy Celestia!" Nightmare had prided herself her ability to goad anypony into playing right into her hands, it was certainly one of her best talents, among some.

"Nice and lazy huh? Just remember Nightmare, you asked for this one!"

"Go ahead then, attack me!"

"Fine!" Celestia charged up her magic, or at least what was left of it into a concentrated beam of focused energy. The bright beam was headed straight towards Nightmare who just had a look of annoyance more than fear. "I'll put everything I have left into this one, then you'll be sorry Nightmare!"

"Are you sure that giving up what's left of your magic is a good idea? Don't let what I say discourage you though! Please, attack away!" The beam hit Nightmare square on her chest and created an explosion all around her! Celestia was waiting for the smog to clear up! When she did however, She saw much to her amazement Nightmare still standing there, unscathed.

"No! I-it's not possible! My blast hit you directly at your chest, how are you still standing?"

"Why not try to figure that one out for yourself, you're smart aren't you dear sister?" Celestia was shocked and now was the time for Nightmare to make her move! "Well you've had your attack, now i'll have mine dear sister!" Nightmare began to slowly approach Celestia, every step she made added a jiggle and a wobble to her massive ass, much to Celestia's further disgust.

'N-no way! My magic isn't doing anything to her, she just shrugged it off like it was nothing. Ponyfeathers no magic left, i'll need to use my hand to hand combat, but i'll have to avoid that ass of hers!' Celestia was running out of both time and space as Nightmare was closing in on her.

"Whatever it is you're thinking about, it won't work on me, i've made sure of that!" Nightmare was now standing right in front of Celestia, she turned her waist around to show off her butt and then slapped it. "Oh yes! You've definitely become more soft and spoiled since our last skirmish together. Let's fix that then shall we?"

"I don't think so Nightmare, you're not going to use your butt on me again! I won't let you!"

"Does it really look like I care about what you will or will not allow? It's time for our playtime together Celestia!" Nightmare tried to butt slam Celestia into the ground, she used so much force that it literally left cracks into the marble in the ground. "You're merely delaying the inevitable dear sister, your face will be buried into my ass!"

"I'm not going through that again, it was horrible the first time it happened! How about this Nightmare!" Celestia had then grabbed Nightmare by the back of her neck and put her into a sleeper hold. "I don't want to have to hurt you Nightmare, but you're leaving me no other choice right now!"

"L-let go of me Celestia! Right bucking now! I'm warning you!"

"No! I will not make this easy for you Nightmare!"

"Fine! Have it your way then!" Suddenly Nightmare bend down , hiked her ass up and then blasted Celestia with a nasty fart.

FRRRPPTT!!!

"Ack... That's so gross and smelly! N-Nightmare, stop this m-madness! It reeks in here!" Celestia was balking at the harsh odor of Nightmare's fart, the vile stench of beans, broccoli, cauliflower, and sulfur tainting the oxygen she's breathing. Nightmare's fart was also contributing to the process of weakening Celestia, mixed with that spiked tea that she drank, Celestia's not looking too good. Anymore and she'll be too weak to fight Nightmare off, she needs to end this fight quickly before Nightmare blasts her again.

"That one felt good to let out! Here, have another one!"

BRRRPPTTT!!!

'Ugh, dear Faust, her farts are just too stinky! I c-can't keep this up! Maybe if I can find a way to plug up her butt, she won't be able to fart on me anymore!' Celestia was getting desperate, so much so that she was even considering sticking her finger into Nightmare's ass to keep her from blasting her with her farts. 'Oh no, i'm losing my grip on her, her farts are draining what's left of my strength away! How in Equestria could Luna create such a disgusting monster is beyond me! But this has to stop, or she'll have her way with me!'

"Don't think for a moment that I don't notice your grip slowly weakening on me Tia! I would estimate that just one more fart would do it. And as luck would have it, this one feels the mightiest! So... any last words before I snuff them out in my flanks?"

"B-burn in Tartarus! T-that's where a bitch like you belongs! Not in my fair kingdom!"

"Well then, time to blast you! Ready in 3... 2... 1... 0!"

PPRRFFBBTTHH!!!

"Ugh, I can't t-take anymore... too m-much stink... h-help me... somepony..." Just like that Celestia had fainted and released her grip on Nightmare and fell to the ground, unable to endure anymore.

"Too bad you couldn't smell more of my farts. Guess i'll just have to wait until you wake up then, so our playtime together can continue! Sweet dreams dear sister!

"Ugh... my aching head... w-what happened? O-oh yeah, Nightmare happened that's what! What!?! My limbs are shackled to my bed! Oh ponyfeathers, this is not going to end well for me." Celestia came to only to realize that she couldn't move from her bed, bound to it by iron shackles, and watching in horror as Nightmare's massive ass was slowly backing up on her!

"I couldn't agree more with you Celestia! But now that you're awake, let's have some more fun together shall we?"

"N-no... not your butt again Nightmare! Please, don't sit on me!" Celestia was begging for Nightmare's mercy, even though she knew deep down that there wasn't any.

"So sorry Tia, but I seem to be fresh out of that flavor, how about this one instead?" Nightmare's ass was looming over Celestia's face now, ready to plunge her head deep into its smelly crevice.

"N-no! Don't sit on my face please! Nooo! Mmmpth!" Just like that, Celestia's face was being buried deep into Nightmare's smelly ass. Nightmare had wasted no time in rubbing and smearing Celestia's tortured face deeper into her ass.

"So then dear sister! How does my ass smell after a thousand years? It's been such a long time since you've experienced the true pleasures of the night! Well to be honest, I really don't care what you think, i'm still going to have my fun anyways!" Nightmare was almost panting at the feeling of smothering her older sister into her nasty ass! "I can't wait to start blasting you again, and where your snout currently is, there would be no escape from my divine hindquarters neither."

'Oh my Faust above, her butt is so toxic, it smells just horrible! Is this what's to become of me forever with this monster? No, I can't allow this, not just for the sake of myself, but for the sake of my little ponies! Ugh, I must prevail, I can't let her ass win this!' Celestia was trying to struggle out of Nightmare's massive butt, only to succeed in burying her face even deeper, now to the point of her snout touching her rubbery ponut, Celestia was sweating bullets, the exact opposite of she had wanted had happened, not that Nightmare was complaining.

"Hmm... Well now, somepony sure is desperate for my butt aren't they? Yes you are my favorite new pet! You may very well consider yourself a princess, and by all blood rights, you're. But what's a princess to a queen? There's no point to fighting this Celestia, you've lost, just accept your new life under me!" Nightmare was now lightly bouncing her massive flanks on Celestia's head, relishing in her cries and groans of disgust.

'Ugh, t-this monster is just so immoral and disgusting, I don't want anymore of her stinky farts, I-I just don't! Luna, if you're still in there, you must find a way out of Nightmare! P-please!' Then to the horror of Celestia, Nightmare blasted her snout with an atrocious eggy and swampy fart, the warm and fetid breeze completely washing over her face, drowning her in Nightmare's stench.

FRRRRRTTPP!!!

"Ahh, smell everything my butt has to offer you dear sister, then surrender to my flanks!" Nightmare was actually becoming aroused with the control she had over Celestia, her marehood was leaking juices all over Celestia's fur and some of it landed on the cracked marble beneath them. "Oh yes, please... struggle more Celestia, Scream for your new queen of the night!" Nightmare was continuing to pepper Celestia with more of her toxic farts just to further hear her cries of anguish, much to Nightmare'a joy!

FFFRRPPTT!!!
BBBRRPPTT!!!
PPPRRPPTT!!!

Each fart caused Nightmare's ass to wobble and jiggle from the force alone! Celestia could swear that something must of died in her ass, it smelt so bad. She could only pray that it wasn't her real sister, the one she truly loves! "How do they smell my new pet? Are they everything you've imagined them to be and then some?"

'Oh man, her ass is showing no mercy! P-please Luna... f-fight it, you have to fight her influence!' Celestia was more then balking at the horrible farts, she was borderline traumatized at this point.

"Eugh! I n-need to escape her awful butt, everypony's counting on me!" Luna came to and was trying to struggle to escape the confines of Nightmare's ass.

'Don't think that I don't sense that you're awake in there Luna! I do and you'll never see that wretched light ever again! Neither will your older sister! All of Equestria will belong to me!' Luna could actually hear Nightmare's thoughts as they bled into her mind, slowly snuffing out her confidence bit by bit. 'Oh, here comes another fart Luna! Just try to escape it! Take a deep breath for me! Nightmare then blasted Luna's tiny form while inside of her ass.

FFFRRRPPHHTTTPP!!!

"Ugh... T-that's so nasty! B-but I will not surrender that easily!" Luna was slowly trying to dig her way out of Nightmare's smelly ass. That was of course easier said then done! "Hear this and hear it well Nightmare! I will escape your ass! A-and when I do, y-you'll be sorry!"

'Big words coming from such a small pony! But I accept your challenge and so does my ass!' Nightmare had then grunted and blasted her again.

BBBRRRPPHHTTTPP!!!

'You'll be drained and then you'll faint, that's what's going to happen to you Luna! You cannot hope to best my glorious moons!' Luna's mane and tail were damp from being trapped inside of Nightmare's ass for so long, her mane was also frazzled, her breathing weakened, her strength waning! Nightmare's anal muscles were contracting and pulling her back into her smelly colon.

"N-no you d-don't Nightmare... I... I will escape this prison!" Luna fought and struggled, but the more she did this, the more tired she got and the easier it was for Nightmare's ass to pull her in deeper!

'Yes... good! Keep struggling in there Luna! Squirm for me! You feel absolutely wonderful in there!'

PPPRRRPPHHTTTPP!!!

Nightmare grunted and blasted Luna a third time! This was almost too much for her to handle, almost! Even Celestia who was still suffering in there was trying to fight Nightmare's nasty farts and so far, not succeeding! "It's so adorable that you two think you can escape me, let alone overpower me! Such arrogance deserves to be punished! And i'll be more than happy to deliver such to the both of you, as many times as it is necessary for you to understand who's in control!"

'L-Luna, I-I knew you were still alive! But please, don't give up and let Nightmare win this, you've got to keep fighting for all of Equestria!' Celestia was hoping to herself that her younger sister was capable of powering through Nightmare's powerful farts and earning her freedom from Nightmare's stinky bowels. 'I-I don't have much air left Luna... p-please, it's all up to y-you now!'

"You know what? I'm getting bored of this, time to move onto phase two of our session for the both of you!" Nightmare actually got off of Celestia's tortured muzzle, relishing in her groans of protest and frantic gasping for air.

"O-oh my goodness, N-Nightmare, you're such a foul demon, not even a monster would stoop down as low as this!" Celestia was gagging on the tainted air that she needed in order to not faint.

"Oh don't worry Celestia, i've got something special planned for you!" Nightmare had then released Celestia from her shackles. Now unbound, she tried to move to get up off of her bed, but she was too weak to do much of anything. "Here, you can join your sister in my hungry flanks now!" Nightmare then lit her horn and blasted Celestia with her shrinking spell. Now she's the same size as Luna was in her dreams, like a breezie.

"Oh... no! I'm so small now! This is not good at all!" Celestia slowly looked up to Nightmare's gigantic towering form in shock and awe.

"So what do you think about the glorious view? Don't I look just sexy to you?" Nightmare was like a towering fifty-foot titan compared to both Celestia and Luna now, their torture has only just begun yet, that much they knew!

"So then little Celestia, how will you fight me now? Your sister is trapped where you're eventually going to go into! But I want to have some more fun with you before that happens!" Nightmare had lifted her massive foot and loomed it over Celestia's body, wiggling her toes as she done so. "Now I wonder what'll happen if I were to step on you like the insect you are? Could you handle it?"

"W-wait Nightmare, you don't have to squish me under your foot, please don't!" Celestia was visibly shaking at the prospect of being smothered into Nightmare's sweaty soles! "No! D-don't step on me, nooo!"

Boom!!!

Nightmare was grinding and smearing Celestia's battered body deep into her sole, suddenly her nose was greeted with a horrible cheesy odor swamping her senses! "Hah! How does it smell down there for you? How does it feel? Please do scream for me!"

'T-this is just h-horrible, t-the absolute w-worst torture by far, and I thought her farts were bad, I was wrong, I was so very wrong!' Celestia couldn't hold back her tears anymore and began to weep both by the weight and softness of her foot, as well as the vile stench assaulting her nose. Nightmare continued to slowly smear and grind Celestia's body deeper into her nasty foot, relishing in her tortured screams of sensual anguish. Nightmare then sat down on Celestia's mattress, wiggling her butt to get herself more comfortable.

"Ahh! You really do make a nice foot cushion for me Celly! Oh how i've dreamt for this day to finally happen, and it is! Prepare yourself Celestia for the grand lunar tour!" Then Nightmare had lifted up her foot to admire her work! Celestia was weakly twitching in the gap between her soles, her face in tears and looking green from the stench! Celestia was trying to wiggle herself free from Nightmare's noxious foot, then she gazed in absolute horror at Nightmare's other foot that threatened to sandwich her in between both of them!

"Here you go Celestia! More smelly foot love for you to indulge yourself in! Please take some of your best and most hearty whiffs of my feet as you can!" Nightmare cackled evilly as her other foot collided into Celestia's horrified face, smothering her back into her cheesy hell!

'I-I can't e-even think straight her feet smell so bad, they're b-burning into m-my nose! L-Luna, please, y-you must h-hurry and e-escape from her butt! Before it's too late for us!'

"I-I'm a-almost there! J-just a little b-bit farther... t-then i'll b-be freed! Hold o-on T-Tia, j-just a l-little bit longer!" Luna was amazingly halfway out of Nightmare's ass. But of course Nightmare had sensed this and then released another thick butt bomb against Luna, further making it even more difficult to escape! The air became warm and heavy with the malicious stench of Nightmare's fart.

PPPRRRPPHHTTTPP!!!

"Ugh... I-I think i'm going to be ill, I can't keep breathing in her f-farts! M-must k-keep trying to e-escape!

'Bravo Luna, you're actually doing very well against my magnificent stench! But unfortunately for you, all good things will eventually come to an end, especially my end!'

"I d-don't think s-so Nightmare! Y-you haven't w-won this fight y-yet! I'll show you how w-wrong you really are!" Luna was trying her best to power through Nightmare horrible ass and onto freedom. Sadly as fast as she had that burst of energy, she ran out of it and was slowly being pulled back into Nightmare's awful bowels. "N-no way... I-I don't want to go back in deeper... n-nooo!"

'And now to seal the deal for you Luna! I've got a nasty and big one brewing deep inside of me! Guess who gets to have the best view and smell of it?'

FFFRRRBBBRRRPPHHTTTPP!!!

Luna was staring into Nightmare's rancid cave in both awe and anguish, fully realizing that she's not escaping anytime soon. Coughing, gagging, and sobbing as she's sinking back into Nightmare's smelly depths.

"Oh dear! It looks like Luna's given up the ghost in there! Who can blame her though, she in the best place ever, deep into my powerful ass!" Nightmare was still rubbing Celestia's body in between both of her awful feet! Celestia was nearly broken by now, she's too weak to to actually do anything! Then Nightmare pulled her feet apart to reveal Celestia's tortured form plastered onto one of her sweaty soles. Then she peeled Celestia off of it and laid her on the marble floor, now lying on her back and looking up to Nightmare's giant body.

"P-please... m-mercy N-Nightmare, I... I beg you... n-no more t-torture!" Celestia was on her last legs and Nightmare could sense it. Nightmare was growing bored of this now! So she's looking to finally send Celestia where she belongs, into her ass. Nightmare then lifted herself up off of the mattress, then she turned around to display her goddess sized ass to the tiny princess made pet.

"Oh no dearest Celestia! It's not over yet! I've still got some more sexy stinky fun to have with you before you go up my ass!" Celestia just stared at that gigantic ass, it was unbelievable just how big it was and the smell... the smell was atrocious in every way imaginable. Nightmare snickered and pulled apart her cheeks to reveal her puckered anus to Celestia, much to her dismay. "Here! I've got more of my sexy stench for you to enjoy Tia!" Then Nightmare grunted and blasted Celestia's tiny form with a thick and warm wall of swampy stench!

BBBFFFPPPRRRPPHHTTTPP!!!

Celestia's mane and tail were being blasted back from the force of Nightmare's awful fart. Green in the face once more and tearing up from the stench, Celestia tried to fight through the powerful stink. But it was an effort in vain, both Nightmare and herself knew this very well. "Ugh... n-no! N-not l-like t-this Nightmare! Augh! I c-can't b-breathe! Salvation... p-please!" Celestia was still holding onto her consciousness, much to Nightmare's surprise. But she wasn't complaining, the longer she says awake, the more she can suffer!

PPPRRRFFFRRRPPHHTTTPP!!!

"I-i'm at my limit! It's getting really bad down here! It burns to breathe them in!" As Celestia said this she noticed that Nightmare massive moons were slowly closing in on her with every fart passed! Nightmare really was cold, wicked and cruel. "N-no! I d-don't want to get s-squished under y-your butt Nightmare! D-do you hear me?"

FFFBBBRRRPPPHHTTTPP!!!

"Sorry Tia, I can't hear you over the sound of how loud my farts are! You'll have to speak louder for me!" Nightmare snickered as her massive flanks were almost on top of Celestia's body! Celestia's running out of time and she knew it!

BBBFFFPPPRRRPPHHTTTPP!!!

"N-no... No! Nooo!"

Crunch!!!

Nightmare's gigantic ass slammed down onto Celestia's body with a crunch sound, Nightmare was sighing in bliss as Celestia was screaming from both the immense weight and the toxic stench of her vile rump! Nightmare's flanks were so heavy, yet so very soft too! They stunk with the fury of a thousand garbage dumps, making it literally unbearable for Celestia to withstand underneath her. The more pressure she applied to her flanks, the farther they squished outwards, like pliable dough. Celestia was completely staggered under Nightmare's butt, she couldn't do much of anything else except for scream, struggle and choke on the harsh stench that Nightmare's ass had more than provided.

"Scream for me Celestia! I want to hear everything!" Nightmare had then started to lightly bounce herself on Celestia's tiny body, making her butt wobble, jiggle, and squish both inwards and out!

FFFBBBPPPRRRPPHHTTTPP!!!

'Ugh... it's too much butt! Oh so nasty... p-please... somepony... h-help me!'

Bounce!!!

BBBFFFPPPRRRPPHHTTTPP!!!

"Oh my goodness yes! This feels so good dear sister! Squirm for me more! Revenge feels so good!"

Bounce!!!

PPPBBBFFFRRRPPHHTTTPP!!!

The horrible stench was flooding both the room and Celestia's senses. Even Luna, who was still trapped was smelling and feeling every painful contraction that Nightmare's bowels did on her body! Both mares were suffering and Nightmare was beginning to finger herself to it! She was panting from the feeling of pleasuring herself to their agony!

Bounce!!!

PPPBBBFFFRRRPPHHTTTPP!!!

"Oh... oh yes! I'm nearly there! Keep squirming for me Celestia!"

"Hey Celestia... Luna? It's me Princess Twilight! Can you open the door for me, i'm getting worried, I haven't heard from you guys in more than two weeks!" Twilight was checking on the two princesses who have mysteriously disappeared and believed that checking their bedchambers would be a good place to start. She focused her magic and discovered a huge magic spike that for any ordinary unicorn, or guard couldn't sense. Even highly trained ponies couldn't sense it, this must be the work of someone very powerful, Twilight was sure of it!

'Oh good, the wretched unicorn that blasted me with that disgusting harmony magic from before! So she's a princess now hmm? How very intriguing indeed! Yes, she'll do lovely as my new pet!' Nightmare then used her magic and teleported Twilight in there with her, shrinking her in the process.

"What the... where am I? I... I'm small!?!" Twilight had then looked on in awe and terror at the grinning goddess sized mare in front of her, fingering herself!

"Long time no see... Twilight Sparkle! So i'm sure you're wondering where the other two princesses are and why you're stuck in here with me, shrunken down and completely at my mercy!"

"I... I don't really know, nor do I really care to be honest, just let them go Nightmare Moon!"

"Then why don't you come over here and make me stop? If you can that is." Nightmare then used her thumb and index fingers to split apart her juicy folds right in front of Twilight, who was blushing and slightly shaking at the immense Nightmare and her magical power. Twilight had then noticed an incredibly foul stench flood her nostrils and she gagged into her arm.

"Woah! It really stinks in here! What have you been doing Nightmare?" Twilight was staggering at the horrible stench of sulfur and manure!

"So then Twilight, like what you see?" Nightmare was beckoning Twilight to fight her, so she can dominate her like she did both Celestia and Luna. She would be damned if she would allow those elements of harmony to blast her again.

"N-no! No I don't!" Twilight was trying to hide her slowly growing arousal from Nightmare, but she failed. Nightmare could see it and decided to have some more fun. The more the merrier right?

"Twilight, don't lie to me, I can sense your arousal and it's slowly rising up! You're welcome to do more than just stare you know! Come and try to stop me!" Nightmare used her hand that wasn't on her pussy to reach out to grab Twilight's small body. Twilight had to think fast or else she'll be getting to know Nightmare a whole lot more than she'd want to. "Just hold still! This won't hurt a bit for you! I promise!"

"Yeah right! I'm not falling for that one Nightmare, you're never going to win this you know, just surrender and we can talk! I can be reasonable you know!" Twilight was trying her best and was dodging Nightmare's grabs, each one more harder to avoid than the last.

"You can't avoid me forever you know!"

"Maybe so but i'll still try it! I will not surrender to evil!" Suddenly Twilight tripped on one of the cracks on the marble ground, not paying attention to them and gasped. "Oh no! Not good! Not good at all!" Twilight's legs were caught in Nightmare's grasp and she was lifted upside down to face Nightmare.

"Looks like you fell for it after all! You're not very good at this game are you?" Nightmare was grinning evilly, she knew she had won this but she still wasn't going to be satisfied until her night was eternal. Nightmare's conquest was going to be completed, and nopony was going to stop her.

"L-let me g-go Nightmare! I'm w-warning you!" Twilight looked scared to Nightmare, she was going to milk this for everything it was worth to her.

Oh dear! The helpless princess dangling from my fingers is threatening me! Whatever shall I do? I have a pretty good idea, but you're not going to like it pet!" Nightmare had gestured her head slowly to her crotch and chuckled. Twilight's blood ran cold, she wasn't going to be used as a sex toy! There's no way she'll let that happen.

"N-no way in Tartarus am I going to go in there Nightmare, you can forget it!" Twilight charged up her horn and blasted nightmare square in the face, even when she was upside down, her aim was pretty good. "How's that for a helpless princess?"

Once the smoke cleared from the blast, she was shocked to see Nightmare completely undamaged. "Mmm... your magic tastes just like Luna's, very nice! I appreciate the snack! Go ahead, keep blasting me, make me stronger why don't you!" Nightmare was licking her lips lustfully while cackling like a mad mare at Twilight's feeble attempt at resistance.

"Aren't you worried that i'll summon the elements of harmony again?" Twilight tried to play her weakness! But this only earned some more laughter from the monarch of the night. Twilight was confused at hearing her laugh, she wasn't suppose to laugh.

"Oh please Twilight, i'll give you points for effort, you've fought more than both Celestia and Luna combined! Commendable, yet futile. I'm already aware that without your friends with you, your precious harmony magic would be useless against me!"

'Damnit, she's right! What am I going to do?' Twilight's body was slowly getting closer to Nightmare's juicy folds, it won't be much longer until she's buried in them! Twilight had then did the only logical thing that her brain could think of doing in such a panic situation as this: Fire more magic blasts at the threat and hope that something works! "I hope this hurts you bad Nightmare!" Twilight fired her second blast right into Nightmare's pussy! Like a sponge, it only absorbed her magic and actually caused more pleasure for the night goddess than it was suppose to.

"Oh my yes! You know Twilight, you're actually suppose to hurt me right? Not make me feel good!" Nightmare was having so much fun with all three of these princesses made pets, all for her pleasure and amusement.

"S-stop m-mocking me Nightmare! That's what i'm trying to do!" Twilight was almost out of time now! She was just a few yards away from Nightmare's pussy now and slowly getting closer too. "Then how's this one for you? I'm putting all the power I have into this one, so it's definitely going to hurt you!"

"You know that plan of attack sure does sound very familiar to me! Maybe it's because Celestia tried that exact same thing and is now squished under my sexy ass!" Nightmare emphasized this statement by grinding her rump more for Twilight to hear Celestia's muffled cries and groans of agony!

"No! Celestia! That's it Nightmare, you asked for this!" Twilight then released her third magic blast, this one being the mightiest of her other two. It was aimed right at her stomach and it actually hurt Nightmare, much to her amazement. Not by much, but it did, enough to piss her off rather than actually do any real damage to her.

"Ouch! You little bitch! You singed my fur! Now i'm mad! I'm going to make you suffer more slowly for that!" So Nightmare had abruptly lifted Twilight away from her pussy, much to her instant relief, but then Twilight was being aggressively shoved in between Nightmare's massive boobs! "I'm going to crush your body in between my big girls Twilight! Then i'll torture you some more before I shove you into my sacred privates!"

Boompt!!!

Nightmare's giant jugs made a satisfyingly deep drum sound when Twilight's body made contact with them. Her breasts were rippling, jiggling and sloshing around her milk from inside them. Twilight's screaming was being muffled the more deeper she was being smothered into Nightmare's breasts! 'Augh! It hurts! Her breasts are squishing my body deeper into them! But i-i'm not finished yet, i'll still fight her even if it's the last thing I ever do!' Twilight held out her arms and legs to try to stop Nightmare's massive breast flesh from crushing her in between them! Sadly, it felt like she was trying to hold back an inky black abyss of soft, heavy and supple darkness, closing in on her and soon to devour her in between them.

"It's pointless to continue fighting this Twilight! Just give up! Nopony has ever defeated my marvelous breasts before. And unfortunately for you, I intend to keep it that way!" Nightmare was slowly applying more and more pressure by pushing her breasts together to further crush Twilight in them.

"N-no! I w-won't be squished by your f-fat breasts Nightmare! I can and will survive this!" Twilight was trying her best but unfortunately for her, she just wasn't strong enough to hold back a goddess's strength, even as an alicorn. "I-I... can e-escape them... j-just you w-wait Nightmare... Augh! N-no! Nooo!"

Crunch!!!

Just like that, Nightmare's breasts have claimed yet another victim for the crushing. Twilight's body was nowhere to be seen, she was buried that deep in between them! "Hahaha! Your struggle is now over Twilight Sparkle! I'll show you an experience of your worst nightmares! I'll flatten you in more then I got something else special for you!"

Crunch!!!

'Ahh! Ouch! That hurts! Her breasts are way too b-big and powerful! And really soft, but not the good kind of s-soft though! I... I must escape from in between t-these boobs before they flatten me into a pancake!' Twilight was struggling and trying to wiggle her way out from in between Nightmare's titanic tits, her breasts have offered Twilight no purchase however, and kept her squashed in between them.

Crunch!!!

"Oh please Twilight! You're no match for my jugs, just keep crying for me!" Then nightmare suddenly stopped. And pulled Twilight's tired and squashed body out from in between her breasts and laid her on the marble floor. "Here! I've got something to show you before your torture continues!" Nightmare had turned around to display her monstrous ass to Twilight, its shadow completely dominating her field of vision. She spread her ass cheeks apart to reveal the weak form of the squirming sun princess, her lower legs wiggling out of Nightmare's powerful pucker. Nightmare's anal muscles were slowly pulling Celestia's groaning and defeated body into its smelly cave to join with Luna.

"Oh no! Celestia! Let them both go Nightmare please!"

"Well then, come and rescue them if you care about them that much!" Nightmare had then turned back around to face Twilight's small body.

"I can still see your burnt fur on your belly Nightmare! That's comforting for me at least!"

"How dare you whelp! Fine then, I think it's time I followed through with your torture!" Nightmare had then lowered her upper body down, angling her boobs so that they'll land right on top of Twilight's body! Nightmare had planned to squash her under her tits! "Here it comes you insufferable whelp! Time to squash you flat!" The already massive shadow of Nightmare's breasts were dominating Twilight's vision, making her more and more terrified the more closer her breasts got to her.

"No! I won't allow this Nightmare! No... n-nooo!"

Boompt!!!

Twilight was actually trying to hold Nightmare's massive mammaries up from squashing her completely. She was willing to use every last bit of her strength in a bid to spare herself of being pancaked underneath Nightmare's tits. "Augh! I-i'm g-going to f-fight this to t-the bitter e-end Nightmare!" Sadly Nightmare's boobs were just too soft for Twilight to get a good grip on them, and way too heavy to lift. Twilight was struggling to hold both of her boobs up, the upper half of her body completely buried halfway into Nightmare's tit flesh. Her legs were wobbling from the strain of lifting up her breasts. "Ack... no! N-not like t-this... nooo!"

Crunch!!!

"Hah! You have lost Twilight Sparkle! To the victor go the spoils!" Nightmare was rubbing her tits all over Twilight's crushed frame, earning more cries and groans of protest from the lavender alicorn. More soft squishes, bounces and crunching, along with Twilight's pained groaning could be heard. "How do you like my big girls Twilight? Do they feel good all squashed over you like this? Squirm for me some more!" Nightmare's breasts were just about, if not more so soft, bouncy and supple, like pliable dough, just like her massive ass. But instead of the foul stench, which will eventually assault Twilight's nostrils, she's hearing the sound of sloshing milk, like an near endless ocean. Twilight was still trying to weakly struggle to escape from her boobie torture. Nightmare applied more pressure with her rubbing and pressing of her tits to make the fat of her breasts squish outwards and completely cover the entire cracked marble of where her ass had originally slammed to try to pin Celestia with.

Crunch!!!

'Augh! I-it hurts so m-much down here! If Nightmare's breasts are this powerful, I can only imagine what her privates must be like, and I don't want to be shoved into there! Ugh! I... I can't m-move, I need help!'

"Ahh! I love torturing other alicorns, their bodies are just so durable and strong that normal ponies and other creatures would just get squashed to death under me! I'm going to keep you three inside of me for all eternity! And there's nothing you can do to stop me neither!" Then Nightmare got bored of squishing Twilight with her tits and then slowly lifted them up off of Twilight's tortured body! Twilight's body was twitching, her face stained with parts of milk from Nightmare's tits and her tears from the torture and the pain of being squished. She looked down at Twilight's crushed body and laughed. "Our playtime isn't over yet Twilight! Now you'll be sent into my glorious depths! My privates await you!" Nightmare then reached out to pick up Twilight's body from the ground and then slowly move her back over to her soaking wet entrance, holding her with her right hand, and pulling apart her dripping folds with her left, Nightmare was ready to shove Twilight's body into her privates.

To Twilight: It looked like a hungry maw, waiting for its meal. The musky odor of a mature moon goddess was piercing through Twilight's sense of smell, forcing her nose to twitch at the harsh smell. This gave her all the more incentive to squirm, cry and shudder at the realization of her next destination, Nightmare's juicy vagina. Using her left thumb and index fingers, Nightmare parted her folds again, showing Twilight her moist cave! Yes Twilight! Get a good look at my glorious pussy, because that's where you're headed now! First i'm going to lubricate your body with my folds, then you're going in deep!"

"N-no! P-please Nightmare... m-mercy is all I a-ask for now! I... I surrender, I c-can't fight anymore. You've won Nightmare! Eternal n-night is now yours, p-please let me g-go!" Twilight was desperate, she did not want to go in there! Anything but there! Nightmare just looked down at her trembling form with her usual nefarious grin and said!

"No!"

Twilight's pupils have turned to pinpricks upon hearing this. She was doomed and she knew it! Nightmare had then began to slowly smear Twilight's head in between her folds, relishing in her cries of protest. "Just be thankful that i've taken the time to lube you up so that you'll go in faster! And if you please me quickly, you'll get out quickly, understood?" Nightmare was beginning to sigh in relief as Twilight's doing more than just making her feel good. She was actually going to make her explode hard if she kept this up! "Ahh! That feels go good my pet, keep fighting back for me! My royal privates are just going to snack on your body until you faint!" Nightmare was so close now, all she needed was a little push more, then she'd hit orgasm.

Schlicking!!!

'Ugh... it's just so musky and gross in here! I... I can't beat her, i'm just too small and weak to do anything to this monster. The longer I'm stay trapped in here, the more I can feel her pussy draining more and more of my magic and energy away! Salvation... please, I don't want this!' Twilight was getting weaker more and more, Nightmare had pretty much won this!

Schlicking!!!

"Oh yes my new pet, you're making me feel so good, i'm so close! Your squirming is just delicious!"

Schlicking!!!

'Augh! It's too much to f-fight against! Why Luna... why did you create such a horrible monster? I can't keep this up much longer!' Twilight was nearly unconscious and Nightmare just needed a little more pleasure to get off!

Schlicking!!!

"Ahh! Oh my Faust above yes! You're doing it my pet, i'm gonna... gonna... Ahhh!" Nightmare came and she came hard, the force blasting Twilight's battered and defeated body out of her marehood. Trapped in Nightmare's pool of discharge, she was lightly twitching and crying from the abuse she's taking. Looking back up to her captor in fear of what's next. "Oh my yes! You were so good, such a tasty morsel for me. But now it's time to send you into my glorious ass! Time to greet your two friends deep inside me!"

"N-no! I-I can't go up y-your butt, n-not like t-this! Why can't you just show mercy? Why do you have to be so horrible?" Twilight was coughing and trying to spit out Nightmare's sexual fluids, then she stared at Nightmare's ass as it was being presented to her. "I'll actually swear loyalty to you, just let me and my friends live please!"

"Oh I don't need to worry about your friends, so long as I have you in my possession, they can't do anything to stop me! To attempt such a thing would be suicide and they know it!" Nightmare's ass was closing in on Twilight's body. Nightmare's ass was now just about to completely sit on her and squish her underneath her mighty backside but not before her anus opened up and blasted Twilight's nose with an atrocious smelling sulfur cloud.

FFFBBBPPPRRRPPHHTTTPP!!!

The force of Nightmare's nasty fart was blowing back Twilight's mane and tail, causing her eyes to tear up from the horrible stench and her face to turn green as well. Twilight was getting weaker from just being forced to breathe in Nightmare's noxious anal air. It was like a warm and thick wall of stench that hit Twilight like a freight train. Twilight was dry heaving from the vile fart blast, then she collapsed on the marble floor and broke out in tears, her hopes dashed, her fears realized, her fate sealed.

Boompt!!!

Then it happened, Nightmare's ass flattened Twilight's body underneath it, her screams being muffled and drowned out by Nightmare's cackling and the thickness of her royal flanks. They squished back out again as they claimed yet another victim. "Ahh... Oh yes! Smell my glorious ass Twilight Sparkle! Then succumb to its stench and then faint so that my butt can eat you too!"

BBBFFFPPPRRRPPHHTTTPP!!!

Nightmare grunted and farted again, swamping Twilight's senses with the worst stench she had ever smelt in her entire life. Nightmare's massive ass was rippling from the force of her farts. Twilight at this point had already given up on everything. She was broken, skunked, flattened, violated, and tortured. Twilight wasn't fighting anymore and Nightmare certainly caught on. "Alright then Twilight, after my next fart, you'll be heading into your new home, with my other two pets! Remember to play nice with them ok!"

PPPFFFBBBRRRPPHHTTTPP!!!

'Augh! N-no! I can't fight this anymore, I-I failed as a princess and a protector of Equestria! I... i'm sorry everypony! I...' Finally Twilight fainted and Nightmare shared out one last hearty laugh before she delivered Twilight to her next destination.

"Well then, I can sense that you're unconscious in there Twilight! Now without further ado, let's finish this up shall we!" Twilight's body had then began to turn into a pale lavender hue, her color was fading away along with her element of harmony. Next her body was wedged in so deep that the back of her head was slowly slipping into Nightmare's puckered anus. Now groaning in defeat like Celestia, she was resigned to her smelly fate. Now with only her feet sticking out, Nightmare blasted her one last time, just because she could, not that Twilight could actually do anything about it.

BBBFFFPPPRRRPPHHTTTPP!!!

Then just like that, her body was nowhere to be seen, Nightmare's ass had eaten the princess of friendship! "Ahh!!! You were such a tasty plaything Twilight, now you're where you truly belong! Hahaha!"

"Oh no... this is not good, not good at all, I need to warn the Crystal Empire right now!" Said a very familiar maid who had watched the entire scene since Twilight had entered Celestia's bedchambers. Then to her absolute horror, Nightmare had looked in her general direction through the keyhole she was using to peek through, then with a sinister grin, she disappeared in a thick blue fog-like mist!

"Why hello there little one! I remember you! You were that annoying maid that asked me all those questions! Well... i've got a special place for you, a place that you're going to absolutely love!"

"No! Noo! N-nooo!"
