Celestia stared at the sleeping form of her sister, her eyes narrowed in indecision. Something told her to stop, some quiet little voice from deep inside begged her to just lay down and go to sleep. She could wait until Twilight got home.

Her hungry tongue licked her lips, tasting the sweat that glistened her face. After hours of masturbating, she was exhausted. Worse, she was still burning with need. Celestia’s hooves were hot and heavy, throbbing from a day’s exertion and wrinkled from being soaked in her ever-flowing arousal for hours on end. She needed something… more.

Anything to hold her over until Twilight came home tonight, or better yet Shining. She blinked, gasping for breath as she once again felt her orgasm slipping from her grip.

“Fuck…” Celestia groaned in frustration. She knew she couldn’t do it. Not since… sometime. She knew what she had to do. What he wanted her to do.

Biting her lip, Celestia tasted iron. She should quit, go to sleep. Fighting this wasn’t worth it.

Or she could let him win. He always wins. God, she loves it when he wins.

Celestia heard her voice ring out, almost playfully. “Oh Luna~! I need you to suck on my pussy until we both pass out. How does that sound?”

Luna lifted her head, seemingly awakened by Celestia’s call. Twilight’s mask kept her actual expression hidden, but her wings fluttered and her back stretched.

Celestia swallowed dryly, watching her beautiful sister rise. Even trapped in the mask and wrapped in enchanted leathers, Luna was sexy as hell. Perhaps more so. Celestia idly tried to remember if Twilight put a want it need it spell on any of Luna’s accouterments, and quickly gave up. Celestia knew she’d fuck Luna naked.

She had yesterday, afterall.

Luna’s response was quick, seemingly eager to play with her. Celestia decided that if Luna did a good enough job, she’d let her cum today. Shining had taught her the trick to flipping her little Luna’s sigil around and turning the pet sister gimp into a pet sister fountain years ago. She just loved watching her little sisters cunt spray all over the room after a week or so of being pent up.

Love and Luna. Something about that gave her pause. Oh well, she certainly loved giving Luna her release.

That intimate moment usually fell to Celestia nowadays, Shining was rarely ever around anymore. Not that it bothered her. Slutty little Luna was always right there to fulfill Celestia’s aching need during the day. Twilight would come by at night to cuddle for a bit, then really sate her desires. It didn’t take much, if anything at all, for Celestia to convince the deliciously stronger mare to fuck her absolutely silly.

When Twilight got serious, Celestia was as weak as a foal against her rough, and sometimes violent advances. The thought brought an uncontrollable shudder to her legs as Luna dipped her snout under Celestia’s tail.

Sometimes she wondered if it had all been worth it.

Shining hadn’t lied to her. She’d been happy since becoming his harem member all those decades ago. Day after day of relentless fucking was exactly what she needed after a thousand years of morose moping for sending her sister to the moon. It was a wonder she never realized it earlier.

It all really started after that one incident that she didn’t remember well. She’d been getting wonderfully intimate with Shining, and he’d pinned her to her back and made her feel like never before. It was the first time he’d made her pass out with his affection, and it was something she dearly wished she remembered. Celestia shifted her legs as the imagined memory warmed her cunt as much as her sister’s wanton tongue.

“Keep it up, Lu~! I’m really worked up. I’m particularly horny today. You can get your rest tonight. Do a good job and maybe I’ll ask Twilight to lick you, too…”

The gentle ministrations of her sister geared up further, causing Celestia’s legs to quiver. Oh, this was going to be good.

“I love you, my little sister slut.”

Luna only aggressively licked in response, the mask sealing any other form of communication from her.

Celestia moaned, leaning back into her sisters hot tongue. Minutes passed, maybe hours. It was hard to tell. Everything felt so nice.

Luna’s tongue was soft, and eager. The heat from her body warmed Celestia’s core, and the pressure made her whole body tingle with glee. Luna was covered in straps and piercings, some jingling as she licked. The chorus of wet sounds mingling with the soft, rhythmic chiming and Luna’s heavy breathing was pure delight to Celestia’s ears.

Shuddering, she pressed Luna’s head deep into her, stretching herself around her sisters snout.

More. She needed more.

Carefully, Celestia lay down on her back, gently twisting and resting comfortably on the soft cushions around the love nest. Luna managed to keep up her ministrations, nibbling and gently licking Celestia’s pussy lips as Celestia sunk into the luxurious cushions.

Celestia groaned, luxuriating in her euphoria as she mentally checked the time. She had a few hours till nightfall. Luna’s tongue wouldn’t get tired until long past. Her magic sigil flared up, eager to cause her more pleasure and shooting a rush of pleasure to tingle through her spine.

She let her hooves wander down to play with Luna’s gorgeous hair. “I love you, Luna…” Celestia spoke gently, tenderly even as Luna lapped at her folds like a thirsty dog at a river. Celestia briefly admired Luna’s extra long and thick tongue, wondering if it had always been so engorged. It’s not like Luna used it for talking much, so maybe it had simply adapted, becoming the perfect tool to lick her cunt.

They were both clearly made to please each other, each designed to perfectly compliment the other’s needs and desires.

This was love. Celestia sighed contentedly as her first squirting orgasm coursed down her body. “Ah… Sis… Sister… I… Ah!”

Luna quietly lapped at her flesh, dutifully suckling and drinking it in.

Celestia giggled as the euphoria passed, watching her sisters lips seal perfectly with her own lower ones. She didn’t know why some mares liked being cuddled and cozied while they fucked. Mouth to pussy was so much better. Cuddling was for before or after.

Celestia grunted once more, thrusting into Luna’s face.

“Yesss… keep doing that.” Celestia praised her, not that Luna needed the direction. Luna knew exactly how to get Celestia to cum, and cum again now. She had for a long time, really.

A vague memory of something… important… shook her mind as her hips rocked and another convulsion caused her to shake. “Have we kissed in a while, ~Lu? Come up here and kiss me.”

Immediately, Luna crawled up Celestia’s body, leaving her still quivering organ to slowly leak between the two and into the cushions. Celestia felt Luna’s body, relishing the heat as she climbed. Hadn’t Luna been cool, once?

Flexing her cunt, Celestia wrapped herself around Luna, and ground her pussy to Luna’s body. She wished Luna had a dick, to fit the memory that she couldn’t remember, but then remembered that there was a spell for that.

Luna’s mouth didn’t wait for permission, instead slipping into Celestia’s like it belonged. In a way, it did. Celestia tasted herself on Luna; salty, raw, and wet was how Luna should be. She nibbled at Luna’s hot lips, using her wings to press Luna into her body. Celestia stared at the mask, Twilight’s cutie mark emblazoned and glowing in her face.

Having the mask so close to her face again made her shudder.

No questions were asked when Celestia wordlessly charged a spell, Luna’s tongue still mingling in her mouth. The spell arched from Celestia’s horn to Luna’s head, shocking her and causing her shudder.

Luna pulled back, knowing that Celestia liked to watch the spell take hold.

Celestia licked her lips, staring hungrily as she desperately begged from her sister. “Don’t stop. Don’t hold back. If you’re rough enough, maybe I’ll let you cum.”

Luna began to writhe in wordless pain. The spell wasn’t normally too terribly uncomfortable, but it usually made the target cum to lubricate the process. However, since the mask augmented sensations, and Luna’s sigil prevented her from orgasming, the change was likely very painful. Maybe she was feeling some kind of blockage as well.

Her midnight blue hair waved as her head shook violently from side to side, and her wings fluttered, pinned tightly to her side by Celestia’s stronger grip. She ground into Celestia’s belly with her cunt, and Celestia was sure she’d scream, if not for the mask. Slowly, her pink flesh grew longer and looser, smearing her arousal across Celestia’s tight belly.

“That’s a good ~Lu… That’s it. I love you…” Celestia encouraged her, pulling her face back down into a deep kiss.

Luna dove into the kiss, pushing her jaw into Celestia’s in an almost painful intensity. Celestia suckled her hot flesh, enjoying the quivering mare as she twitched on her belly. Soon enough, her sister’s twitching slowed down into occasional twinges as her body adjusted to the painfully engorged clit.

Pulling on Luna’s hair, Celestia separated their faces. Luna couldn’t see her, but she could hear. The mare quietly and dutifully watched her sister. “~Lu… You know I love you. It’s time for you to love me…”

With heavy breathing and without out hesitation, Luna slowly drug her giant clit down Celestia’s belly and in between her legs while Celestia pushed her down.

Luna’s spell-warped flesh was fattened like a worm, long hot and raw. It nearly burned with heat as Celestia felt it thrust into her, filling her body like it filled her unconscious. The quiet voice, the unsettled sensation silenced as Luna declared her love to Celestia. Over, and over again. Exactly how Celestia liked it.
