Princess Luna was in a foul mood.
It had already been a particularly long night. It wasn’t as if the day were simply going to come sooner… although she probably could have convinced Celestia otherwise. The mare sat glumly on her balcony, looking out over Canterlot with a deep mental frown. The invisible force field preventing her from inconspicuously leaving only made her want to scowl harder, even though she couldn’t actually see it.
You see, Princess Luna had a particular problem.
It was that time of the month again.
Luna did not experience certain cycles like other mares did. ‘Heat’ was never exactly the problem, although it definitely was a problem of sorts. A very, very horny problem, to be exact.
Due to Princess Luna’s extended stay on the cosmic rock, she had developed a rather personal connection with a being that had fused it’s being with herself.
“Holy fucking fuck, Lulu! This is new one amazing!”
I beg to differ, she thought loudly. Luna released a little gasp as she clenched the cool balcony ledge a little harder, the stiff rubber riding up into her a little higher. She felt her hips lowering onto it a little faster, and let out a quiet breath as the slim pink rod pressed a bit harder into her.
Whenever Princess Luna was as she normally was, she never would have succumbed to such frivolous activities such as these, and certainly not on her bedroom balcony where anypony might see or hear her. Unfortunately, the spirit of Nightmare Moon was granted control during her cycles, meaning…
“Meaning that it’s Moony’s chance to ‘cum’ out and play!” Luna heard herself squeal in delight as she wriggled pleasurably onto the ridged dildo, poking wetly against her tight walls.
Ahh! Not so fast, Nightmare, that hurts!
“Oh?” the spirit teased her, using one of her hooves to slide her slit a little to the side as she leaned a little more over the balcony, spreading her legs some more. “Don’t lie to me, we both know we love it rough.”
Luna gasped again, both internally and externally as her plump pink posterior poker pushed deeply into her again, and the heat growing in her belly seemed creep up into her chest. The warmth seeped through her neck the harder she thrust, even spreading lightly on to extend all the way up to her face.
If anypony sees us, I swear to the Titans…!
“You can’t tell me you’re getting embarrassed now, are you, Lulu?” Nightmare Moon grinned, magically pulling at the replica stallionhood a tiny little bit at a time, hotly tugging it out some more. Luna bit her lower lip, automatically squeezing the tip as it was stickily embraced inside her. She moaned again, breathing heavily as she began reaching climax again.
At the very least, slow down, Luna tried to negotiate. I just came, give us a moment to recuperate, you rambunctious cur!
“Oh, please,” Luna’s eyes rolled against her will. “We both know you love it. Stick it in a little more!”
Luna moaned, the tightness growing painful in her lower belly. Her hooves trembled as she thrust into herself, and another climax began approaching rapidly.
“… Wait,” Nightmare Moon grinned suddenly, freezing up her muscles.
“Oh, now what?”
“I have a better idea,” she hummed aloud, grin curling onto her lips.
“I don’t like the sound of this.”
“New plan!” Nightmare smirked, forcing her legs upward sharply. Luna hissed in equal parts pleasure and pain as the length was stiffly stuck even further into her when she did so, but the entity controlling her body made no move to stop. Instead, she headed straight for the door where the usual invisible force field would contain her, preventing them from leaving.
It’s not going to work, Luna thought loudly, bracing for the impact.
“Then we’ll break through it!” Nightmare Moon said determinedly, heat burning her cheeks. “I can’t make do with things like this anymore – I need to get laid too, dammit!”
“No, wait!” Luna said aloud as Nightmare controlled her hooves over the doors, shoving them open. “Call somepony in, get some poor guard, anything – we don’t need another rampage!”
It took them both a full beat to realize something as Nightmare Moon walked them down the empty hall.
“… There’s no force field,” Nightmare Moon furrowed her brows suspiciously.
“Forget that, I still have my ass full of-”
“Meaning it’s time to go and violate your sister!”
“Hold on, what?!”

Celestia shifted comfortably on her large four poster bed, the silken sheets tucked firmly up to her chin. Her blindfold with double suns painted over them crinkled a little as she moved, her heavy breath the only sound in her room. She had been smack dab in the middle of a rather pleasant dream, although she couldn’t quite remember what it was about. Perhaps she could ask Luna when the spoke again.
She tried to fall back asleep, but couldn’t quite manage it. Perhaps it was because of the hour.
Perhaps it was because she was very interested in remembering what the dream had been about.
Perhaps it was because her sister was indulging in cunnilingus between her sheets.
“Luna!” Celestia gasped, attempting to rip off the blindfold. She felt her magic stifled almost immediately as she tried to use it, her wings and legs tied to each of the beds iron ends as she was carefully spread apart. The blindfold on her face slipped a little, but only a tiny bit on her left side, making it incredibly difficult to see.
“Ah-ha!” Luna heard her own throaty cackle filling the room, power coursing through her veins. “Free at last to extract my revenge upon you, Celestia!”
“Nightmare Moon!” she gasped, wriggling helplessly beneath her. “Release me at once, foul demon!”
“Oh, you shall have your ‘release,’ Celestia…” Nightmare crooned with a wicked little giggle, hoof sliding tenderly between her legs and down her thigh.
“No – you can’t mean…!”
“That’s right!” Nightmare Moon crowed victoriously, shadows beginning to swarm around her and coagulate between her legs into a steadily growing imitation penis. “I’m going to pound your plump posterior until your pretty pink poon spurts seven streams of straight sunshine all over my packed black and purple phallus!”
“I’ll bet you can’t say that seven times fast,” Celestia smirked.
“I’ll bet you can’t say that with your mouth full of my dick.”
“But-”
Celestia’s eyes bulged as Nightmare’s shadowy boner hotly filled her mouth, the hard tip poking against her wet cheek. Nightmare Moon hissed in pleasure as she slid it further down her throat, and her sister thrashed pitifully against her magical hold. Every tight pump led her a little further down her alabaster throat, pushing forcefully against her whipping tongue.
“Ahh, take it deeper…!” she breathed, just as Celestia began to gag. She choked hard as Nightmare suddenly pulled out of her mouth, wiping a bit of her own saliva across her face.
“You-you will never get away with this, Nightmare Moon,” Celestia coughed weakly, the dark alicorn’s smug look of assurance implying otherwise.
“Oh, I think I shall,” she grinned, hoof placed directly atop Celestia’s belly and pushing down slightly as she stroked herself with her other hoof. “After all, how do you intend to stop me with your precious sunlight when I am overpowering you?”
“Zounds!” Celestia gawked. “You fiend!”
“Bwa-hahahaha! The erection shall last forever!” Nightmare boasted, her throbbing and bobbing tip nudging ever so slightly into Celestia’s parted lips. The alicorn wriggled and writhed beneath her, but could not escape the mystic invisible chains that held her. Mostly. “Now, cower before the might of my stupendous shadow schlong!”
“You sure are – ahh~h! – taking pleasure in alliteration, aren’t you?”
“Taking pleasure in your hole,” Nightmare grumbled under her breath. She leaned back with one hoof on her hip, taking her time in sliding her black length ever so slowly in and out of the helpless princess, who arched her back with every stiff prod.
“Ah! Not so f-fast…” Celestia panted, cheeks a ruddy color. “Guards!”
Hardly a moment later, her bedroom doors burst open, leaving a slightly surprised looking guard blinking before the pair. Nightmare Moon, however, didn’t so much as slow her loud, wet thrusts into the moaning sun princess.
“W-what are – oo~h, that’s deep – what are you waiting for?” she looked pleadingly at the armored tan pegasus, who saluted swiftly.
“Yep, gonna need backup,” he turned on the spot, only for Nightmare Moon to magically snag him by one of the wings.
“Get back here and fuck me, you little idiot,” Nightmare whispered dangerously into his ear, and he gulped. The guard nodded swiftly as he was drawn up behind her, and she could feel that he was already hard. "Just stop gaping at me; get busy and gape her."
“Turning my own guards against me?” Celestia pouted as the black alicorn paused for a moment to allow the guard time to spread her cheeks a little and take in the sight. “Truly, you are a monument to wickedness, Nightmare Moon!”
“Yes!” her lascivious smile grew as the pegasus slid into her nearly dripping slot without another moment’s pause. “That’s ri~ght… he, too, is under my spell!”
“I am?” he blinked.
“Just shut up and thrust your hips, idiot.”

Luna awoke feeling refreshed and cheerful as a spring daisy. Sunlight filtered in through the open window and splayed across her as she reclined peacefully against the pillows. She blinked groggily a few times, stifling a yawn.
The unarmored guard beside her shifted quietly in his sleep, a single snort escaping him.
“Uh…” Luna stared at her sister, who was sitting opposite her with a steaming cup of coffee.
“Whoops,” Celestia said without a hint of remorse. “Looks like I might have forgotten to put up the barrier again. My bad.”
“What’s the damage this time?” Luna cringed.
“Oh, I think it’s been pretty well contained,” she answered after taking a long sip from her pink mug with a smiling sun on the side. “Nightmare Moon was no match for either my incredible skills or my ‘elite’ guard.”
Luna blinked again and glanced over at the unconscious pegasus, who was drooling a little.
“… Elite.”
“Well, mostly me,” Celestia admitted, and placed the tip of her hoof on her blazing sun cutie mark. A single trail of steam rose up as she made a hissing noise, and giggled.
Luna rolled her eyes, but her little smile grew as well. It was silent for a few long minutes, the only sound the low breathing of the snoozing guard.
“… So,” Luna cleared her throat awkwardly. “Same time next month?”
