Polyamory

Celestia tried very hard not to watch, but it was a lost cause. It wasn’t just the sight of her sister’s hot sweaty body pinned between the monsters either, but also the view of Shining’s plot. The stallion’s balls swung hypnotically as they smacked the belly of Celestia’s arch-nemesis, or one of her nemeses at least; she had a few. She eventually gave in, slipping off her royal shoes and sliding both front hooves between her thighs.

Just rubbing one out wasn’t breaking her vow, right? Celestia and Luna had rubbed each other plenty since Luna’s return. She had a few second thoughts about her decision when she overheard the guards at the door whispering, making a 100 bit bet on whether Celestia would join or not. She was nearing her peak though, ready to pop, so she wasn’t going to stop.

Celestia’s blush reached new heights as Luna was getting sperm blasted into her from two directions. Celestia wanted to be disgusted at the lewd display of bestiality, but seeing them enjoy Luna, and each other, made them so cute and personable. They shared the same love for one another that she and Luna shared; maybe they weren’t so different.

Luna looked at Celestia and smiled. Celestia wasn’t sure why that embarrassed her; Luna had seen and helped Celestia masturbate before. Perhaps it was the look Luna gave, inviting her to join her debauchery.

“Newly benefited friends,” Luna announced as the drones were pulling their sticky sausages free from her, “It appears that my sister may also require assistance. Let us go inquire of her if we may be of service.”

Celestia swallowed as Luna slipped off the table and walked towards her. Thorax staggered across the table, an excited grin on his face and still-firm drum stick bouncing beneath him. Doomie appeared more worried, pushing ahead of Thorax as if he thought Thorax needed protection from Celestia. He might have been right.

“Sister,” Celestia made clear, “We have been over this; I have no intention of breaking my vow, definitely not with changelings.”

“My, my, sister,” Luna tsked, “Surely such racism is beneath us. We must strive to be an example of just behavior for our subjects.” Luna respected Celestia’s choice and directed her changeling friends, “My sister, the Princess of the Sun, has taken a vow and does not wish to be penetrated in either her vaginal or anal cavities. Therefore, her relaxation must be achieved without doing so.”

“Oh, um,” Thorax quirked an eye ridge and tilted his head, then hopped off of the table, slipping beneath it instead, “Don’t worry Miss Celestia; I’ll be really careful!”

Damnit, why did the dirty little changeling have to be so adoracute? She hadn’t noticed them being this adorable before, but here they were.

“How about her mouth?” asked Doomie, to Luna instead of Celestia.

“My ‘oral cavity’ is also off limits to male anatomy,” Celestia growled, “And I... oh dear.”

Thorax, beneath the table, politely nuzzled at one of her front hooves, which had ceased their movements but still pressed against her pussy. He wrapped his tongue around it several times, slurping off the cream before nuzzling it out of the way. Celestia was so stunned at the sudden affection that she didn’t stop him as he slid his tongue against her soft wet slit.

Celestia took a deep breath, hooves quivering as she placed them on his head. She considered pushing him away, but he was respecting her ‘limits’, even refraining from pushing her labia apart with his tongue. Perhaps it’d be fine. She blushed and bit her lower lip as she looked over at Luna’s somewhat smug face, and let her new ‘friend’ help her relax.

“Maybe you could just lick me?” suggested Doomie.

“I advise you not place your erection within biting distance,” Celestia growled at him, though without the anger of her previous warnings.

Doomie blinked, but got the idea. Instead, he moved to Luna, moving behind her. He slurped at Luna’s best bits for a few moments before he pulled back, doubling himself over and pushing his erection into his own muzzle. He swished fluid around to re-lubricate himself with Luna’s sex slime, then slipped beneath the table, mounting Thorax.

Luna purred as her juice was extracted for Doomie’s own purposes, then slid up to Celestia and hugged her. Luna cuddled her streaming mane against Celestia’s and pulled the table cloth up so they both had a good view of the brotherly incest. Celestia had to admit that the little humping drones were adorable.

“Surely you know that I only want the best for the sister that I love,” Luna said as she briefly kissed Celestia’s cheek.

Celestia moved a wing around to hug Luna in return and leaned into the snuggle. Thorax and Doomie both moaned, drunk on the sudden burst of sisterly love.

“These princess bitches are tastier than most married couples,” Doomie whispered to Thorax, and Celestia couldn’t help but smile upon overhearing him.

Beneath the table, Thorax flagged his tail out of the way to let Doomie penetrate his rectum. Thorax’s muzzle pushed against Celestia’s with each thrust of his brother’s hips. Now both of them licked her, whirling their tongues around between her thighs like they were waxing a floor, exponentially increasing her pleasure. They avoided penetration well enough, but that didn’t keep them from taking turns pressing their muzzle against her princess pink and sucking out juice straight from the tap.

Celestia took a deep breath, placing each of her front hooves on either’s head, snuggling Luna closer with her wing. The changelings nibbled at her clit, then each attached to one of her nipples, slurping and tweaking at them as their tongues slurped downward over her slit. Her release approached faster the more they played with her, the wet noise of their slurping accented with the smack of their hips as Doomie drilled Thorax.

“They have surprisingly broad girths and highly gratifying ridges upon their equipment,” Luna whispered to her, “Are you certain you do not wish to partake? A solitary word is all that would be required... is my sister certain she wishes to forgo such a delightfully carnal opportunity?”

Celestia wanted to say no, but she still didn’t want to break her vows with a changeling even if she broke them, so nodded weakly. It wasn’t just racist this time; it was more the idea of breaking her vow with a stranger.

Celestia’s thoughts ceased as she arched and moaned. Her tunnel convulsed, drenching Thorax and Doomie’s faces with her thick juice. She grasped their heads more firmly, and then squeaked as she pulled Thorax too hard, her labia popping around his muzzle. Once inside, Thorax couldn’t help but take a nice long lick about her soggy flesh canal. Celestia shivered all the more, grasping his head in both her front hooves and violently thrusting against him several times to ride the rest of her solar flare.

Thorax’s tongue lapped all the way to Celestia’s cervix. Upon coming down from her high, she pushed both their heads away, nearly falling over backwards, and would have were Luna not pressed against her. Luna must have realized that Celestia just got her insides tasted, as she smirked wickedly, lapping at Celestia’s face. Luna was kind enough to not break her cover for the moment, but Celestia dreaded the teasing she’d get later.

Celestia couldn’t warn Thorax to not tell what he’d done, since she’d be admitting to the others what happened, so she hoped he wasn’t a bragger. She breathed deeply as she recovered from her high, still hearing the rapid smack of flesh down there.

Celestia slid down enough to see the action beneath the table since she loved a stallion that knew how to take a hard one from behind. The two changelings were going at it like rabbits, Doomie’s hips a blur, their heads thumping against the table as they squirmed. Doomie hugged Thorax’s hips, giving Thorax a gentlemanly reach around, via Thorax thrusting through one of the holes in his hooves. It was disturbing, but also kinky. Celestia hated herself for loving the view.

Thorax must have liked getting a fat one up the behind, because he came first, making another sticky puddle on the floor for the poor maids to clean up. His greenish changeling cream deflected on impact and splattered around them. Doomie followed, clenching his teeth, groaning, and blasting his own load up his brother’s rear. He rolled his eyes back as spunk drooled down his balls and thighs.

Celestia took a deep breath and looked up again. She placed her drenched front hooves upon the table again, drying them off with napkins before slipping her front shoes on. She couldn’t help but chuckle when she overheard the guards who made the bet arguing if Celestia getting licked constituted breaking her vow.
