Then It Might as Well Be Mine
In the gardens outside her palace, Celestia sat on a bench, soft, clad in a glimmering, clinging dress that accentuated as much as it hid, chiming giggles trickling from her lips.
Beside her, on the very same bench, was Shining Armor—Cadance’s husband. He was not a permanent resident of the palace, but neither was he an uncommon sight, for his wife came often to visit her peers and he seldom stayed behind.
At the moment, he was trying to focus on making conversation. His efforts were admirable, but Celestia did her best to emulate the sun, which of all the things out there was among the very hardest to ignore when it did not want to be ignored. And hers was a viciously beautiful figure.
Especially when she was wearing miniscule swimwear, as she was now.
“I must apologise for how distractingly revealing my bikini no doubt is, but I simply can't be in a dress when the sun is this hot,” Celestia said, holding a hand to her chest. “And it's such a hot day, why, your clothes are practically melting off you! I can't for the life of me imagine how or why that's happening…”
Her eyes strained lust through cunning, exuding just enough to coax the reaction she wanted from her most recent partner, but not so much he didn’t think he was just imagining it.
And so, when she finally remarked on how he was looking at her, his cheeks flushed embarrassed red. He felt shame, and she was there as a comforting figure.
It was nothing to be ashamed of, she told him. She was flattered, in fact. She spoke of the danger of letting urges go repressed for too long.
Luna withdrew from the dream at about that point. It was of a sort as old as time; she didn’t need to keep watching to have a sense of where it was going.
Or of what ought to be done about it. Lusty dreams were a dime a dozen, sure, but a princess’s dreams would always hold more weight. Another woman coveting a married man, she’d let go with only a few subtle words of guidance, if that. But Celestia dreaming of Shining Armor…
The moon had been raised, and several nightmares curated already, that night. She had time to set her sister straight in person.
Again. Honestly, it was a wonder Equestria hadn’t been burned down, with a thousand years of Celestia under its proverbial belt. Not many were fortunate enough to have such a caring younger sibling who could keep such a close eye on them.
Luna set off from her room, down the hall towards Celestia’s. Her tread was nearly silent, her bare feet like ghosts over the carpets of the castle hallways. Celestia’s room was just a little ways down the hall. There were no guards in sight, which might have made Luna shake her head disparagingly another night, but on this occasion it was a welcome convenience to approach the door in private. She didn’t bother lifting a hand to open it; a thought was sufficient to wrap the knob in the undulating grip of her magic, twist it and push the door open. She slipped inside, gently closing the door behind her. The room was dim, at that hour, but she’d spent so much time there her mind filled in the gaps the shadows left. Tonight, though, her focus lay on the bed, where her sister lay in that tangle of lurid dreams.
At this close proximity, she could see glimpses of them even without stepping into the dreamscape. Misty figments and snippets floated above Celestia—in all of them, she was unclothed, in half her legs were spread, and in the other half her head was in Shining Armor’s lap.
Most improper.
With a thought, Luna undid the strings holding her gown up, and let it slip down to the floor. The fabric sighed, and so did she; the people had grown prudish since her banishment, and too rarely now could she walk in naught but her skin and the cool night air. Her sister’s room was well-guarded from prying eyes, though.
She walked forwards quietly, her bare feet sinking into the luxurious carpets as she approached. Celestia lay on her side, facing the door at least for now. The state of her sheets told a story of restless wriggling.
A very small part of Luna felt a tiny twang of guilt for sneaking in uninvited, but, well… when someone had the duty of raising the sun each day, you really wanted their minds to be clear, and Celestia would find a dozen excuses to avoid scheduling any remedies—which some would put forward as a compelling argument that certain princesses had given of themselves so much that they needed to put themselves first for once in their life.
The bed was fairly new. And, according to Luna’s specifications, sat at a very particular height.
It wouldn’t be the first time she found herself asking forgiveness instead of permission.
Celestia opened her eyes, and it was only a thousand years of composure that kept her expression of surprise to a bemused twitch of her lips.
It was the dead of night, her room was dark, and Luna’s cock was right in front of her face. A thought and a little flick of magic lit a candle by her bed that made one of those things go away, but the other two remained, the latter particularly salient.
“Good evening, sister.” Luna’s voice came from above, beckoning Celestia’s eyes upwards. She saw Luna standing over beside the bed, stark naked.
They were quickly wrenched downwards when Luna rolled her hips. Her cock crept closer, already stiff and hard, insistently reaching for Celestia’s mouth.
“Luna,” Celestia said. “What are you doing?”
Luna clicked her tongue, reaching down to cup Celestia’s chin. “Come now, dear sister. It does not behoove you to call yourself a ‘what’.”
She inched closer. Celestia’s field of vision was steadily swallowed by Luna’s dick. “Fair point,” she said—and as soon as she’d finished, Luna took advantage of her mouth being open and stuffed her cock in it. Celestia instinctively pulled her teeth back, greeting the familiar warmth with soft lips and a loving, curious tongue.
The twin novelties of Luna having a cock and that cock being inside her mouth had worn off quite some time ago, but there was always a kind of… juvenile delight associated with it. She thought of what all her subjects would think if they saw Luna stuffing her mouth like that, and she felt so young, so daring and audacious.
She heard a soft groan right as Luna’s sender hands came down to run through her hair. Luna’s cock grew slowly in her mouth, unfurling and stiffening gradually as she traced her tongue over its veiny contours.
Celestia shifted her posture, propping herself up on her elbow. She slipped Luna’s cock out of her mouth, but swiftly wrapped her fingers around it, so that it never went neglected. “What’s the occasion?” she asked between steady pumps of her hand.
“Do we need one?” Luna insistently pushed forwards, as though she wasn’t going to be satisfied with just a hand.
“I supp—” Celestia didn’t manage to get all her planned words out this time. Luna thrust between her lips slowly, groaning softly.
“I saw you were dreaming of someone tonight,” Luna said. Her voice felt strained.
Celestia made a thoughtful hmm. Her dreams had seemed vivid at the time, but present company made them muted and dull by comparison. She pulled her head back, placating Luna with kisses and nuzzles to her tip. “It was just a dream,” she said, just before flicking her tongue out for a lap. It came back carrying a bead of tangy, cloying precum, which she eagerly swallowed. Nighttime chill nipped at her, but warmth bloomed in her breast.
“But you understand my concern,” Luna said, stroking Celestia’s hair, “given who you were sharing it with.”
“Do you think so poorly of my restraint?” Celestia pulled away long enough to sit up, briefly abandoning Luna’s loins. She slipped the straps of her nightgown off her shoulders, sliding the flimsy garment down and off and throwing it aside.
A pause, and then a giggle. “No,” Luna said. She stalked forward, lowering herself onto the bed and slinking over to sit beside Celestia. “I trust you to keep dreams and reality separate.” She shrugged, then, putting her hand on the back on Celestia’s head and guiding it downwards. “But it makes for a good excuse, doesn’t it?”
Celestia shot Luna a glare. “You could have asked first.”
“I could have.” Luna spread her legs apart, and Celestia moved to settle in between them, lying on her chest and kissing Luna’s tip. “But I quite like where my methods took us.”
Celestia bit down just hard enough to make Luna wince, hiss and squirm.
“Fine, fine.” Luna shifted uncomfortably, her grip on Celestia’s head relaxing. “Next time I’ll ask.”
“Mmm.” Celestia gave a few gentle bobs of her head. A thing string of spittle connected her lips and Luna’s shaft when next she pulled back. “No, you won’t.”
“Of course I would.” Luna gave a haughty snort. “What sort of dastard would ignore a plea from her own sister?”
Celestia idly suckled on Luna’s dick. “You would.”
“You…” Luna’s breath hitched, her eyes rolling back as Celestia pressed her lips to her crotch, deepthroating her with ease. “… you are absolutely correct,” Luna panted, “because you are the best sister I could ask for and know me so well.”
If it was possible to smile while a hair’s breadth away from choking on cock, Celestia would have done so. As it was, she gifted her sister’s twitching phallus with several bobs of her head, taking it all between her lips each time. Luna mewled quietly, her breaths quick and heavy.
“Of course I do.” Celestia switched back to nuzzles and strokes. Luna writhed, rolling her hips forward, begging for Celestia’ mouth, but Celestia held up her hand and blocked her with a palm. “So what kind of sister would I be if I didn’t return the favor?”
“What? Tia, what’re you—?”
Celestia sat up. With a flick of her wrist, she wrapped Luna in a telekinetic sheath and flipped her over. With an indignant squawk, Luna fell on her chest, quickly pushing herself up onto all fours.
At which point Celestia leaned over on top of her, reaching around to grab her dick—as soon as she had a hold of it, Luna went still. She must have been tantalizingly close to orgasm before Celestia stopped.
“Fair’s fair, isn’t it?” Celestia asked. “You were concerned about me sleeping with a man, so… I think I should be shown the error of my ways, don’t you agree?”
“T—Tia, there’d be time for that in j—just a few more—”
A soft golden glow flowed out from Celestia’s hands, and flesh reshaped like clay underneath her fingers. Luna’s thick, dripping cock retreated back into her, leaving a damp, winking pussy where it had been, just as a long, hard dick sprouted from between Celestia’s thighs.
“Oh, yes, you’re right.” Celestia clicked her tongue, snaking an arm around Luna’s hips, inching forward and lining herself up. “Pity we didn’t talk this over more, isn’t it?” She clicked her tongue, shrugging innocently. “Oh well. There’s always next time.” She pushed forwards.
Somehow, after all these years, that first thrust into Luna’s pussy always exceeded her expectations. She was so warm, so wet and snug like that part of her had been made solely for Celestia’s cock.
Luna’s thoughts were of a very similar inclination, if the way her protests died out the second Celestia was inside her. She let out a relieved gasp, scooting backwards to grind her rear against Celestia’s stomach. “Yes,” she panted, “next time.”
Smiling, Celestia leaned forwards, running her hands along Luna’s torso, briefly cupping her dangling breasts before winding her way up to her cheek. “I think there will be quite a few next times,” she whispered, putting on a tender smile as she coaxed Luna to turn her head for a kiss.
While they were in that position, Celestia lamented how having Luna face down meant her lovely, modest round breasts were going to be hidden. But that was one more reason for there to be a next time, she mused as she gave one a quick squeeze.
The second the kiss ended, Celestia wove her fingers through Luna’s hair and pressed her head downwards. She pulled her hips back and started thrusting—her lips parted in a smile at the little squeaks and groans her little sister made.
“You know, whether you asked or not…” Celestia quickened her pace, driving her hips into Luna’s over and over and over again. “I’m glad you came to see me tonight.” She pinched that sentence off with a grunt and a gasp. It felt like she’d been afflicted with an itch all day and only realized it was there when going balls-deep into her sister made it go away.
“I am—” Luna panted and moaned, arching her back and bucking her hips to match the rhythm of Celestia’s thrusts. “—known for my good decisions,” she added; her voice had turned breathy and addled, the words she put together staggered and muddled.
For once, Celestia looked at where Luna’s decisions had led them and couldn’t find it in her heart to argue. She kept up her assault on Luna’s pussy, her own breasts bouncing in half a dozen directions.
Finally she felt that familiar pressure rising in her shaft. She bit her lip, her eyes rolling back in her head—there was nothing in the world but her shaft buried deep in Luna’s pussy. They must have reeked of sex by that point, must have been slick and shiny with sweat, but Celestia didn’t notice any of those things.
She heard Luna cry out, and with it came a cascade of sensations. Luna’s hips bucked wildly, all sense of rhythm lost—her inner walls spasmed, their grip on Celestia’s shaft darting to and from a vicious tightness. Juices splattered out of her, squirting out and around Celestia’s cock to the sheets below them.
And just when that whirlwind had died down, Celestia’s bloomed. The pressure in her cock climbed to a zenith and plateaued when she just couldn’t hold onto it any longer. She convulsed, ramming her hips one last time against Luna’s, struggling to keep them there as thick spurts of cum erupted from her dick.
Perhaps she cried out herself—it was impossible to say. But what she did know is that a few moments later, it was all over. Her cock slipped out of Luna and she slumped forward, falling down to her pillows. In the dead of night, it felt like she’d been basting under the sun.
She turned over onto her back, vaguely aware of Luna lying beside her. Her breasts heaved slowly, in time with her labored breaths.
“You should…” She bit her lip, taking a few moments to calm herself. “You should get going,” she said eventually.
“Done so soon?” Luna pursed her lips in a pout, reaching for Celestia’s cock. “The night is still young.”
Celestia sighed softly at Luna’s touch, momentarily adrift in bliss. But she reined herself in after a moment, and took Luna’s hand in her own to bring it to a standstill. “I’ve got a long day tomorrow. I’ve already lost too much sleep,” she said.
Luna did that sideways glare she made when she wanted to argue but also knew her stance was wrong.
She let go of Celestia’s cock with a quiet huff. Then she nestled up close to Celestia, resting her head on a large, pillowy breast.
“Luna,” Celestia said. “You have your—”
“Five minutes,” Luna said.
Celestia pursed her lips, thought for a moment, then snuffed out the candle. Darkness fell over them again; she leaned in to give Luna a kiss on the forehead and wrapped her arms around her. “Alright,” she said. “Five minutes.”
She could picture Luna’s smile clearly, even though she couldn’t see it.
“You know,” Luna said, her voice low and soft, “if we were to step down…”
Celestia closed her eyes, sighing. “This again?”
“Twilight is ready. We both know that.” Luna’s arm drifted down to Celestia’s waist; she traced circles on Celestia’s hip with her finger.
“We do. But it’s… rather irresponsible, isn’t it?” Celestia laid her head on top of Luna’s, letting her eyes fall closed. “I always imagined I’d step down when… when something happened, not…”
“Think it over,” Luna said. She buried her face in Celestia’s cleavage, going limp and quiet.
Celestia nodded silently.
Close to an hour later, she shook Luna awake and whispered, “time’s up.”
