Celestia gets Lunar Eclipsed!

"So Celestia, I have good news and bad news. The good news is that I'm no longer evil; the bad news is that I got Luna to enjoy her inner decadence." Nightmare said smugly.

"Y-Yes, Sister, mine, it is true. I-I do enjoy working with her; we make the most potent team together." Luna confessed with a blush.

"Luna… she's poisoning your mind."

"Oh, of course, you'll say that, Celestia. We're two halves of the same coin, Luna and myself. She is not complete without me, as I am not without her. We compromised; I promised not to be evil anymore, and she would join me." Nightmare said as she jiggled her gargantuan asscheeks.

"And I am so delighted that she came around, sister. I confess, my inner darkness is… kinda sexy." Luna admitted.

"T-This has to be another plan of hers, Luna."

"Aha! That's the reaction we expected, Celestia. You can't handle the truth; the truth is that we're not just friends; we're lovers." Nightmare Moon said triumphantly.

"We love each other, Celestia; it's nothing like what you have with me, you see," Luna added.

"And if you think we won't take over Equestria as soon as we're done with you, you're dead wrong," Luna added again after a pause.

Nightmare then grabbed Luna's slightly smaller but still massive butt with her hooves to gingerly massage them. "And we'll not abandon you, either; you are our sister; after all, we'll keep you around as our new plaything."

"N-Nightmare Moon, you said you abstained from your evil."

"It's true; we did, and it wasn't easy either. We had to overcome a lot of our self-restraint." Nightmare Moon confessed while stroking the base of Luna's horn.

"But now that we don't have any restraints left, we're free to do anything we want. And right now, I want to fuck Celestia's will until she can't think anymore." Nightmare finished as she pressed her lips against Luna's.

"So shall I start with her first, dearest, Nightmare?" Luna asked as she broke the tender kiss with her dark ego.

"What am I, chopped liver? I will not be bullied by you two." Hah, she said, bullied, as if she could stop them.

"You can't win here, Celestia, and we both know it. We are the superior beings; you are just a pawn in our game, and I intend to enjoy myself thoroughly until I have fully claimed Equestria for our own. Now come to us, dear sister; let us taste your lips." Nightmare Moon whispered as she licked Celestia's horn, making the alicorn shudder.

"I am ready to strike first, Nightmare. Tia will be underprepared for this attack."

"Hmm… I can't wait to watch it."

"Luna… don't you dare come any closer with that big butt…" Luna pushed her underwear-clad butt into Celestia's face.

"Now, now, Celestia. We have you exactly where we want you. Don't resist us now. You'll have plenty of time to recover once we're done." Nightmare Moon giggled before licking the tip of Celestia's horn, wrapping her lips around it, and beginning to suck it to weaken her as her face was smothered in Luna's rear.

"Just lay back and enjoy, sister; we know exactly what to do to please you," Luna whispered in a husky tone as she rubbed her butt into Celestia's face, moaning as she felt her sister's snout sinking in deeper.

Celestia fought against this as she grabbed Luna's asscheeks with her hooves to push her away, but Nightmare's tongue flicked on her horn, making her flinch.

"Now that we are both horny, how about we share you between us, Tia?" Nightmare said as she licked Celestia's neck and cheek and massaged Luna's ass in front of her.

"Oh, Nightmare… you're such a tease. If you keep doing this… I-I might." Luna's bowels were rumbling with a round of fresh gas.

"No- Luna, don't you dare…" Celestia said as she was terrified of what came next.

"We have the perfect way to relieve our pent-up energy, Tia, and it involves both of us overwhelming you at once. I think it's only fair to share because we haven't shared anything with you." Nightmare Moon explained as she rested her head on Luna's right buttcheek and began to massage her butt more, eliciting a surprised moan from the princess.

"W-What are you doing, Nighty? S-Stop teasing me." Luna begged in a whiny tone.

"Oh, don't be such a prude, my love; I know you want this as much as I do. And you know I love your rump more than anything." Nightmare grinned evilly, knowing Luna was ready to hit Celestia's poor nose with a deadly fart.

"Oh no… I must pull myself free before she-" Luna then moaned lewdly as she blasted a dense, pungent blue fart into Celestia's face, which stunk like an open manhole cover.

Both cackled in a seductive chorus while Luna rubbed her rump against Celestia's face.

 "Oh, Tia… I promised not to do this, but I can't help myself." Luna blushed as she looked over her shoulder and whispered. "Your face is so cute and vulnerable, covered in my fart. It's so embarrassing."

 "You are a slut, Tia; You took in Luna's nasty fart like a champ. I hope you're enjoying it. And I'm getting more turned on by the minute." Nightmare taunted as she watched the sun princess squirm underneath them.

Celestia's legs shook as she tried her best to remain strong as Luna's fart slowly tore apart her will. "Ugh… oh, god, that stinks like rotten cabbage mixed with shit."

As Celestia was being tortured by the smelly stinkbomb that was Luna's fart, Nightmare kept playing with the alicorn's body, licking and biting her neck and occasionally whispering things like "Her smelly ass is so tasty," or "Your face is so adorable." In contrast, Luna kept rubbing her butt against Celestia's muzzle.

 "You like it? You know you do, Tia. Just give up and let us play with you." Luna said as she wiggled her hips teasingly.

 "I know you want to be our plaything forever. You need a little encouragement to make you give in." Nightmare giggled as she bit down harder on Celestia's neck, making the alicorn whimper.

 "Give in, sister, mine, or you sniff in more vile flatulence." Luna licked her lips salaciously.

"T-This is by far… the w-worst… smell… w-worse than Tartarus for miles."

Luna and Nightmare laughed lewdly as their rumps began to shake like jello; Luna kept grinding her rump into Celestia's face while Nightmare staggered her by sucking on Celestia's horn like a lollipop.

 "That's the point, Tia; I'm gonna make your head so full of fart that you'll be forced to inhale every last fart I release until you've lost your mind," Luna said as she rubbed her butt in Celestia's face. "Now get to it!" Luna said as she shoved her huge bubble butt right into Celestia's face, leaving her unable to breathe.

Even Luna's underwear was laced with traces of her rotten flatulence; Celestia's face was entombed within Luna's lethal asscheeks and whiffing in her stinky undies.

"I knew you loved my stinky butt so much that you just couldn't say no," Luna said as she ground her rump against Celestia's face while keeping her ass firmly planted on top of her sister's snout.

 "Yes, dear sister… you like Luna's flatulent rump so much that you'll lick it clean of its foul stench. Isn't that right?" Nightmare asked as she nibbled Celestia's ear and teased her horn while stroking the latter's base.

 "Yes, it is true, my beloved; Tia is getting the lunar treatment from us," Luna replied while her giant ass completely enshrouded Celestia's head.

Celestia's body shivered and lightly convulsed from the foul stench as Luna hit her with a second nasty fart.

The duo laughed at the alicorn's reaction to their gas before turning back to each other and smiling as they realized how much they both loved inflicting their farts on Celestia.

"So… how shall we proceed? Shall I finish her off or let her experience the joys of the lunar treatment longer?" Nightmare asked as she nuzzled Luna's rump.

 "Hmm… I think a slow knockout by farts is too easy. Besides, you're right; I do have an idea." Luna smirked evilly. "Let's see how well she handles you, Nightmare," Luna suggested as she and Nightmare switched places; now it was Nightmare's turn to smother the alicorn with her ass.

Celestia was only given short brevity to get fresher air into her lungs as Luna switched places with Nightmare. "No… her ass is much bigger… Luna, please… nooo!"

"Ahh, my ass feels so good on your face, Tia. I don't think you can imagine how much I missed your face being buried between my buttcheeks." Nightmare Moon cooed as she rubbed her rump into Celestia's face like a horny horse humping the ground.

 "It feels so nice on top of your face that I just can't stop farting. I'm just going to keep farting until you pass out." Nightmare laughed maniacally as she pressed her asscheeks down harder onto the princess.

 "I know you want more of our butt stink, Tia, and you're loving every second of it," Luna said with a giggle as she began licking Celestia's horn just as Nightmare did; Nightmare's ass was like a massive Grim Reaper of pure fat and flatulence.

The smell was stinking and very… strong. This was what darkness smelt like… oh, the horror.

"Well? How do you feel now, Tia?" Both Luna and Nightmare said at the same time.

 "It seems you enjoy being buried in our rumps much more than I expected." Nightmare added while she continued to rub her ass in the sun alicorn's face.

 "I hope you enjoyed the first round of our buttfarts. I know you liked it, and we have plenty more in store for you." Luna giggled as she massaged Nightmare's buttcheeks with her hooves while Nightmare rubbed hers before Celestia's face.

 "Oh, yes; your face has been coated in so much of my farts that it smells like mine. However… oh, I can certainly make it smell worse." Nightmare licked her lips lewdly.

"T-Too big… too deep… help…"

"Oh, Tia… I can see you struggling in Nightmare's ass, but we both know it's all in vain." Luna whispered authoritatively as Nightmare rubbed her ass against Celestia's muzzle like a pillow.

 "I can see your eyes rolling back from all the flatulence; just accept your fate." Nightmare said with a chuckle while she kept rubbing her ass over Celestia's snout and nose, making her whimper pathetically.

 "Don't worry, Tia; we'll take good care of you. Just submit to us; let us own you and break your resistance down; let it crumble; your will shall fade like your flimsy monarchy." Luna added as she started to lick Nightmare's rump.

They were both the unstoppable force and the immovable objects; they gave no quarter to Celestia as her nose was filled with Nightmare's venomous butt breeze. If Luna's butt was like spoiled cabbage and manure, then Nightmares was everything that was manifold. Such a staggering, lethal aroma that would paralyze Celestia's body the more she whiffed it in.

"That's it, Tia… surrender to us, sister," Luna said while licking Nightmare's neck and biting her earlobe as Nightmare thrust her butt into Celestia's face.

 "You love being buried in my stinking fat asscheeks; you know you do." Nightmare added while she ripped more pungent farts into Celestia's snout and taunted her with her words. "What do you call an alicorn whose will was whittled down into mere whimpers and grandiose delusions of hope?"

 "We both know you love this; we could tell thee the answer, but we're certain the smell can do better than our words." Luna chuckled as they overpowered Celestia, who felt too weak to fight back.

"P-Please… I beg of you two… have some mercy on me… I can't… this is too much to handle…"

"Mercy? What's the point of mercy if we already have you?" Luna asked as she pushed Celestia's face into Nightmare's ass.

 "But there's no reason to be shy about it anymore. Now tell us… who do you belong to?" Nightmare asked as she rubbed her fat rear against the alicorn's snout.

"We know you want to give in, Tia; your heart will not stand up to mine and Nightmare's butts," Luna added while licking the tip of Celestia's horn.

 "Come now, sister. We are waiting for your answer. Who owns you? Who controls your destiny?" Nightmare cooed sadistically as she delivered more repulsive vapors into Celestia's tormented nose.

"I-I surrender… please… I concede; free my nose from this Hell."

"See? Wasn't that so easy?" Luna said while licking Celestia's horn with the tip of her tongue and looking into her weakened eyes.

 "I told you we could convince her, Nighty. And you were right; she is a submissive slut; we just had to play the right cards." Luna said while wrapping her lips around Celestia's horn again and sucking on it.

 "Oh, but she did try her best; to her credit, she didn't faint. Most that we face together have been forced to sleep under us." Nightmare said, feeling fondness for that memory.

"S-So… you will free me from your asses then?" Celestia asked in a hopeful tone.

"We have a better idea." Both Luna and Nightmare said as they licked their lips in anticipation.

 "Now that we have your will, freeing you is unnecessary." Nightmare whispered as she rubbed her butt against Celestia's snout again, making her whimper in protest.

 "You belong to us; we own you. That is why we've been trying to break you." Luna added while rubbing her rump against Celestia's snout as well.

 "But now that you're broken in, we must ensure you will never resist us again." Nightmare added with a laugh. "So, we have decided that the best way to make you our eternal plaything is to make you our new wife."

"Indeed, you shall be wedded to us once you awaken; we'll have total control upon thine will, however," Luna said sweetly.

"Y-Your w-wife…" Celestia shuddered as she heard their plans for her.

"Yes, sister, mine. But first, we shall make you sleep underneath us. While we prepare for the wedded ritual, you shall be trapped in our special Dreamtime. You'll be rocked to sleep by our rotten fragrances." Luna moaned as she blasted her farts again into Celestia's groaning face.

"Oh, Luna, you have become so cruel, commanding, and corrupted… so hot." Nightmare boxed Celestia's whimpering face with Luna as they both gave the defeated sun princess a booty sandwich of her worst nightmares.

"P-Please… not like this… I don't want to be put to sleep like this…"

"Shh… just sleep, sister. You can either sleep under us willingly or be forced to inhale more farts until you lose consciousness." Luna said as she squeezed her buttcheeks around Celestia's nostrils and mouth.

 "Say goodnight, Celestia! You can rest while we rule Equestria as the true queens." Nightmare said as she rubbed her asscheeks in the alicorn's face. "Sleep and be ours, sleep and relinquish your duties and troubles, sleep and submit."

They blasted one last fart into Celestia's sobbing face as she fell asleep in their cozy but smelly asscheeks.
