Polyamory

Luna understood her sister’s embarrassment, and knew that despite her determination not to ‘judge’ Luna, Celestia preferred not to witness Luna’s illicit activities. Luna herself was glowing red from what she was doing, though it didn’t show well beneath her dark purple coat. Despite that, she knew that it’d do Celestia good to see the doubled fun she was having.

“I apologize sister,” Luna said with sincerity, “I assure you I was uninformed of Princess Cadance’s intentions prior to this session. I am inclined, however, to exploit this opportunity for a new experience.” She looked at the two changeling drones that Chrysalis had brought. “If you desire to approach the Princess of the Night with erotic intent, you have leave to do so, but do recognize that the regulation forbidding you from changing forms still holds.”

“No judgements,” Celestia sighed, the tone of one trying to convince themselves of what they say. She was looking forward, hooves neatly folded in front of her. Celestia didn’t watch yet, but Luna doubted she’d keep that up. Celestia had trouble keeping her eyes off Luna’s plot in the most dignified of situations.

Both changelings approached Luna with great excitement, climbing over the table at her since that’s what everypony was doing. The first, the one that had looked so hopeful, was hyperventilating at the chance to get inside Luna.

The drones seemed high, which Luna assumed was from love fumes permeating the room. Luna let her own feelings run wild, giving them plenty more to keep them as intoxicated as possible.

The first tugged Luna up onto the table with him, pushing his muzzle against hers. He frenched with such eagerness that it was a wonder he didn’t tie his tongue in a knot with Luna’s. Luna went wide-eyed as she realized how long and dexterous those forked tongues were, and slid her hooves over his body to feel the strange scaly chitin covering him. Others had described changelings as frightening creatures, but these two were nothing short of adorable as far as Luna was concerned.

The second fluttered his wings, moved behind her, and gave her plot a firm push to put her onto the table. He licked his lips as he tugged her tail upward, his eyes on the prize that was her tight rear entry. As the first seemed more than okay with Luna’s front side, both changelings sat up on their haunches to pin the large mare between them. Luna shivered at the pressure of their thick ridged shafts against her fur, slick with natural lubrication from within their sheaths.

“So uh, nice to meet you, I’m-“ The first started as they separated from the kiss, but Luna shushed him with a hoof. He wanted to converse during the act, but that was a privilege reserved for her sister.

“Please refrain from divulging your identity at this time.” Luna dominated even when pinned between two drones ready to pound her. “Sexual activity with an unknown party adds an element of licentious taboo, which I currently find desirable. You may reveal your designation after you have sated yourself with my body.”

Luna glanced at Celestia and found her staring, saliva dripping from the corner of her muzzle. Celestia looked forward again when she realized Luna was observing her in return, gnawing her lower lip. Celestia’s hooves quivered on the table as if she would much rather them be underneath giving her drenched lower quarters a rub. Luna grasped the first drone closer, turning and raising one hind leg to make sure Celestia could see some juicy penetration.

The two excited drones lifted Luna’s bottom off the table as she raised her hind legs, sandwiching her between them. Their legs flexed as they pulled her up higher, nestling their tips against her openings. The first nestled himself between her lower lips, which salivated moon butter down his egg beater to blend with his natural lubrication. The second found Luna’s rump tight and dry, but wouldn’t need to worry since his pleasure plunger glistened with his own viscous grease.

Luna held the first with her forelegs as her rear legs spread, then hugged the second with her wings, grasping both males as they yanked her downward. She relaxed, allowing them to push up into her, lips and pucker stretched wide over their lengths, sliding down and flicking against each ridge as it popped inside. Each pushed balls-deep into her, their balls pressing together as they both penetrated. Such unique breeders, so many ridges, such an incredible feeling.

Once they were inside, Luna clenched as hard as she could, and the males shivered against her in response. The second groaned as he was grasped so tightly that he had to strain to force his way in and out. His eyes rolled back, hissing as he thrusted upward. The first hissed as he worked at Luna’s front door, sultry slickness already drooling down his balls as they smacked against the second's with each thrust. Luna squealed in delight as she bounced on the dual spikes impaling her. Such shameless indulgence made her feel young again.

Luna rolled her hips instinctively, but didn’t have to move at all as the drones held her off the table. She slid one hoof down to feel the shape of both shafts as the two throbbing members bulged her belly. Luna kept her hind legs lifted, letting them buck her up and down, soaking up the pleasure of her newfound sexual freedom.

Luna wanted Celestia to see her bliss so she would remember what this was like. Even Luna had remembered things she had forgotten, like how she and her sister had been so popular with stallions, particularly as a pair.

Celestia looked impressed when Luna glanced back. She was staring again, though with her muzzle closed this time. Her hooves were still on the table, but kept pulling downward before she moved them back with solid determination. It was like her logic parts and fun parts were arguing about what she should do with those hooves while she watched. The fun parts must have won the argument because she slipped them all the way beneath the table. The chair rocked as she rolled her hips and rubbed her under-used slit to the sight of her sister slutting it up with a pair of drones she had met minutes earlier.

All Luna needed to know about the nameless strangers was that they had amazing cocks. Their equipment gave such unique pleasure as they pistoned into her. Her flesh canal squeezed up and down the first as she milked him, her lips snapping audibly against his ridges with each pass. Luna’s pucker was even louder, and the juices blended as their balls smacked together. It kept her bowels slick and still provided sexy suction.

Luna kissed the one in front again in her excitement, enjoying a nice tongue battle with him before turning her head about and giving the second an equally deep kiss. Once done, they leaned around her and kissed one another, ramming their tongues down each other’s’ throat so forcefully that Luna could see their necks bulge. It was nice to see that they also shared a special sibling love. The drones even lit their horns, each massaging the others cum pouch as they continued to bounce together.

Luna’s whole form tingled, quivering more as her peak approached as she kicked her hind legs spastically on either side of the first changeling’s hips. Her tail squeezed the second one so hard that he gagged from lack of air. Both love tunnels erupted into a flurry of convulsions, clenching with rolling motions over her lovers’ plungers. Both drones squeaked and then pulled their heads away from each other as if they’d bitten one another’s tongue from sudden bliss.

Luna clung to them, lest the geysers of thick foreign seed throw her off the table. The greenish goo dyed her inner flesh before spraying out through the tight penetrations, combining with her own glee to spread a steaming mist around them. When the convulsions ceased, they clung to one another in blissful afterglow.

“Wow,” said the first, “A-also... my name is Thorax.”

“Doomie,” panted the second.

“Does this mean we’re friends now?” Thorax asked drunkenly.

“Perhaps,” smiled Luna weakly, “As long as your subsequent actions are also friendly in nature.” She added in a whisper,”If all goes well, you may invite more of your siblings to partake of me on your next visit.”
