The aurora shined down, and the full moon cast thin shadows in the night. Wind off the mountain face blew across the ice castle's balcony, ruffling Luna's feathers and the hairs that had escaped Elsa's braid.

Elsa moved and kneeled down, planting her knees on either side of Luna's ears, and lowered herself down onto her elbows, her head just above the base of Luna's tail.

"I approve of your thinking," Luna said.

Elsa looked down, under her own breasts, abs, and bush, and smiled at Luna. Luna winked, and then reached up with her tongue and brushed it across Elsa's underside, a shot running from her wetness straight to her head, making her vision sparkle and her eyes widen. Her body spasmed and she gasped, right hand clenching the dildo.

As her lick tickled the bright-pink inner lips, Luna studied the sights in front of her. She could see better in the dark than most ponies could see in full sun, so all of Elsa's hidden glory was revealed to her. The clit, throbbing with her heartbeat, glistened with her wetness. Silken hair, so blond it was nearly white, curled in tight ringlets across her pubis, thickly across the outer lips, and then ran up into her crevice between her buttocks. Luna added a hint of levitation, spreading Elsa's bottom wide.

She gasped but then arched her back. "Like what you see, Luna?"

"Indeed!" The blond hairs thinned to nothing as they progressed past her rear entrance and up her backside. Luna brushed Elsa's clit with her tongue, and the pale-colored hole clenched in response. "I do, indeed."

With a deep breath, Elsa lowered herself to her elbows and took in the sights before her eyes. The tail swished, its long hairs melding into an ethereal flow. Luna's hips and abdomen rippled with her lean strength, every breath emphasizing the sharply defined muscles beneath the fur. She stared. The soldiers and handymen around the palace were muscular, of course, but in a bulky and rather crude way. Anna's beau was built solidly, but not in any way that drew Elsa's eyes. The young women around the palace, the maids or cooks... well, Elsa had often let her eyes take in their forms: they were all healthy and strong, as long days working with the hands and their backs required, but none like this. Her mind fought for the word; if Luna were a human, how would she describe her appearance?

Elsa then ran her fingers along the inside of Luna's thigh, and felt the hard muscles beneath the downy-soft coat.

If she were a human, she would be a marathoner.

Those thoughts cut off as Elsa's breath rushed out, Luna's tongue swirling against her clit, then Luna's lips clamped down, sucking on Elsa. Lights like the aurora flashed in Elsa's head as fire lit inside her belly. Such a sensation! She had rubbed herself off before falling asleep every night (not just monthly, as she had earlier lied to Luna) ever since the whole 'frozen summer' incident, but in all those months, she never felt anything like—

The tip of Luna's dildo touched Elsa's opening, just past Luna's massaging lips and tongue, and her vision went dark as it slid in, splitting open her channel while the tongue kept working, fire and ice so close to each other the sensations crossed and melded together.

Into her, deeper, Luna slid the dildo further in. Like an avalanche letting loose after a mountain blizzard, Elsa lost control. The who-knew-how-long of their earlier talking and teasing and playing had left her pent up, and this dildo was twice the diameter of any Elsa had used before, so it split wide her pussy, queens can think pussy while they cum, it doesn't have to be so formal, split it wider than it ever had been before in her life, her virginal snatch stretching and fighting the insertion, but she was so wet it slid in just fine, and it was ice and Elsa was the Queen of Ice, no its Goddess, and it went in deeper still—

Elsa raised her head to the sky and moaned, loud and deep. Her back arched.

Luna watched Elsa's response to her ministrations. The powerful orgam made her squirt into Luna's mouth, a hot flow of thick excitement slicking Luna's tongue, tasting like honey and fire. Elsa's pussy clenched on the dildo, trying to force it out, but Luna nudged it back in. She placed her forehooves against Elsa's bottom and spread the cheeks open. The alluringly puckered bumhole clenched and winked in time with the grinding of Elsa's hips and clenching of her pussy.

Elsa grabbed Luna's tail with one hand and pulled, her long thumbnail scratching up and down its dock, the pain of the tug shooting up Luna's spine but actually feeling rather good, in a naughty sort of way, pain turning into excitement as the muscles around Luna's belly clenched in response, Luna's thighs momentarily clamping tight against Elsa's shoulders, and her own pussy was throbbing now, hot and slick, ready for Elsa's touch.

"Luna!" Elsa moaned. "That—I've never felt like that before."

She pulled her mouth away from Elsa's snatch with a pop, a thick string of Elsa's excitement connecting Luna's lower lip to Elsa's clit. She gathered it with her tongue and swallowed. "I'm glad, Elsa, that I can make you happy."

Elsa panted, one hand on the ground and the other pressed against her heart.

"Elsa?"

"Yes, Luna?"

"My love is unsatiated."

Elsa shook her head, clearing out the last sparkles of light that the orgasm had left behind. She looked at Luna again, but this time focusing not on the muscles and midnight-blue coat and the whole of her, but instead, focused intently on Luna's private area. The blue hairs of her coat grew short over her mound, but still covered her outer lips. Inside them were bright pink inner lips and Luna's opening. Her clit winked out of its hood, huge, reddish-pink, and demanding attention.

She hesitated, though. Her whole life—there had been humans, and there had been animals. Luna seemed not to hesitate for a moment to make love to her, but Luna had grown up in a place where many different animals could be people: ponies, donkeys, mules; hippogriffs, griffons, deer; so many others. Luna must know, deep in her heart, that personhood came in many packages.

But Elsa hesitated. Her mind knew that same lesson, but could she make her body...?

Another shudder rippled up Elsa's spine as Luna began to slide the dildo in-and-out, building into a wonderful rhythm. Elsa blinked stars out of her vision and looked at the marehood in front of her. This was most certainly a person, one who could sense Elsa's moods, and what to say or do to put her at ease.

She lowered her head and breathed in deeply. Luna smelled not like an animal at all: the very faint hint of soap from her bath could still be smelled, but it was almost lost under the thick and wonderful musk of Luna's excitement, her nethers wet and dripping.

Elsa bent down and kissed lightly on the dark blue coat of Luna's dock, the short hairs tickling her tongue and lips and nose.

The tail smacked her across the head. Elsa squeaked, closing her eyes and hunching her shoulders.

"Sorry!" Luna gasped. The tail smacked Elsa's head again. "It's somewhat of its own mind, especially when my attention is split. You may be forced to ice it to the balcony. I do not mind."

With a small chuckle, Elsa ignored the ephemeral hairs batting the top of her own scalp, and reached with the dildo. She brushed its tip up-and-down, dragging its rounded tip along Luna's lips. Luna's flows began in earnest, thin fluid slicking the dildo and the pink folds, soaking the blue fur of the outer lips, dribbling down and wetting her dark-blue tailhole until it shined.

Soft fur touched Elsa's belly and breasts as Luna arched her back. Luna moaned into Elsa's pussy, the sucking and stroking of her dildo losing their rhythm and turning random as Elsa teased Luna's lips. Fire lit inside Elsa's channel, the ice dildo feeling like a billet of white-hot iron from a blacksmith's forge, the fire ran around her pussy and up the cleft of her bottom to her spine, where it spread across her entire body, the sensations of the warm mouth on her clit contrasted against the cold air against her skin, and the stroking, stroking, stroking of the hard dildo going ever deeper, driving her inexorably forward.

She bit Luna's pubic fluff and gave a little tug. Luna squealed and shivered. Elsa clamped her own lips around Luna's huge clit. The nub pulsed in surprise, pushing against her tongue, and Elsa's eyes widened as she tasted the body of another person (or pony, or whatever, don't worry about semantics) for the first time. Luna's muscles tightened under Elsa's torso. Wetness coated Elsa's tongue. It struck Elsa with its sweetness, like candy, but also deep and complex, with fruity undertones the castle sommelier would have tsk-tsked at Elsa for failing to identify.

Luna's juices were glorious, and Elsa's greedy sucking moved down from her clit. She pulled the dildo away to make room for her mouth to clamp over Luna's lips. Elsa sucked and massaged, her lips melding into Luna's pussylips, warmth upon warmth, the soft inner lips and the downy fuzz leaving Elsa's entire face atingle, the sensation unlike anything she had ever known. The smell of Luna's intimacy filled Elsa's nose, so strong it filled her entire mind, the wetness coating her cheeks and chin, intoxicating and leaving her more light-headed than could be blamed just on the thin mountain air.

"Elsa, release yourself," came Luna's words from under her bum. "Holding your magic in check will leave your pleasure in check, too."

Cold swirled around them, a snow squall blowing across them with sudden wind. Freezing fog blotted away the aurora and the moon as Elsa's control slipped, but who cared? She couldn't hurt this ice castle, and she couldn't hurt this partner, this lover, alone of any she might ever sample.

"Good!" Luna gasped, "Now, toss away your last hesitation. Let it—"

Elsa's magic came in its full glory, and the storm erupted down off the mountain, cutting off Luna's words, blowing across them as they desperately made love. Sleet pattered against Elsa's bare back but she ignored it. She blinked ice crystals from her eyelashes. Luna's sucking and tonguing grew faster and faster.

Elsa drove her tongue deep into Luna and pulled it back, sampling the juices from far inside, and the taste deepened, complexified, hints of blackcurrant and lavender, just a slight bit of peppery heat, too. This pony was complex on the palate, indeed! Luna screamed, a high-pitched keen into the night, and drove the dildo harder into Elsa, tilted its end up so that its tip tilted down and it hit the sensitive spot on the front of Elsa's vagina, and Elsa felt herself go over the edge, and new orgasm striking her. Lighting flashed in the raging snowstorm, the clouds lit with brilliant white light in time to her muscles clenching down around the dildo.

Elsa ground her hips down against Luna's face and heard a hollow thonk over the wind as the pony's skull and horn hit the balcony.

Immediately, Luna buried her face harder into Elsa's nethers, sucking and probing fervently, tongue circling her nub and lips massaging, the dildo buried fully inside, and Elsa did the same, mouth and lips around Luna's clit, fingers pushing the dildo in until it hilted against the end of Luna's canal, then stroking it in-and-out.

Ice-crusted feathers touched Elsa's nipples. Goodness! Even Luna's wings were firm, thickly muscled, their tips brushing the soft down of the feathers firmly against Elsa.

Pleasure rose in Elsa again, a third orgasm building, the blizzard around them so thick she couldn't see past Luna's head, and she concentrated, fighting to keep her mind focused on Luna, feeling Luna's responses as the fire crashed in waves across Elsa's pussy, her own muscles clenching on the dildo and her clit throbbing against Luna's tongue, she rode the wave of pleasure and tilted her head, running her tongue around Luna's clit. Luna bucked underneath her, her own pleasure driving her to the edge of control.

Luna's horn discharged with a snap, and the illusory aurora surrounded them again, its pinks and greens and reds lighting up Elsa's billowing snow and fog, their two spells melding and merging and becoming one as they both gave up on control, the pleasure of their bodies driving their magic, their powers combined around them just as intimately as their two bodies were joined.

Elsa grimaced as every muscle in her belly clenched with the height of her own orgasm, her vision blackening and her ears ringing, even the smell and taste and tickle of the fur against her cheeks fading away as her entire mind focused on the clenching, clenching, clenching explosion inside herself—

She drove her tongue against Luna's clit, slammed the dildo deep into Luna with one hand, and yanked Luna's tail with the other, all simultaneously.

Luna's shout tore across the mountain, left Elsa's ears ringing, and the fountain of magic that blasted from Luna's horn at her own climax lit up the entire mountainside and valley in a daylight-bright flash of auroral reds and blues. Luna squirted, spaying a tremendous quantity of her marespunk into Elsa's mouth, and across Elsa's chin, even some getting up her nose. She swallowed, treasuring every drop as it burned down her throat with a tingle of the pony's magic, and Luna's body bucked several times beneath Elsa as the aftershocks of the climax rebounded up and down her spine.

After a second, gentler, tug of the tail, Elsa released it, and slowly withdrew the dildo. She pushed up to sitting position, and hiked up a leg to lever herself off Luna.

Luna pulled the dildo from Elsa and collapsed backwards, wings, legs, and tail splayed, head flat on the icy balcony.

They stared at each other as they both caught their breath and dripped their juices onto the balcony.

The snowstorm and the false aurora faded away, leaving the two of them again under the clear sky, the full moon, and the true northern lights. Half an inch of fresh snow, crusted with ice, covered the balcony.

Blue eyes met blue eyes with a smile. Elsa raised the dildo to her mouth and licked the juices from it. Luna took the other dildo and sucked it clean, too.

Luna rolled onto her belly and flagged her tail high, letting the night air cool her down. Elsa lay down onto her own belly and scooted close, her right side to Luna's left. The balcony's ice on her engorged nipples left a pleasant chill to help cool down the post-orasgmic heat.

They turned their heads and kissed, nuzzling each other. Sticky juices on their cheeks and chins smeared together, transferred back as forth as they nuzzled and kissed, licking clean each other's faces. Flawlessly smooth skin and silken coat rubbed against each other, the sensation new to them both, but the gentle sensuality helping them come down from their excitement, back toward normal.

"Wow," they both said, after the minute or two. Luna furled her left wing over Elsa, soft down brushing smooth skin.

"Better than your other time?" Elsa asked.

Luna chuckled. "Much."

"Thanks for—for making my first so good."

"We shall need to do this again. I have many ideas."

Elsa looked at her and cocked an eyebrow. Luna's horn glowed, and the dildo floated up, in front of them, growing and shifting, expanding, and a second dildo sprouted from its end at a ninety degree angle. "I place one of these ends inside myself, and then I can mount you like a stallion—"

"No! I mean, no thanks," Elsa said with a frown. "I don't think I would like that... at least, not yet."

With a nod, Luna evaporated the dildo to steam. "Plenty of ideas. We need not decide now, and I should never insist on something you didn't desire."

Elsa nuzzled her cheek again, and closed her eyes. "I feel the aurora," she said. "Its magic is falling down upon us. It's warming my butt!" She chuckled. "Thank you for teaching me that... for everything you've taught me."

"I think I've learned quite a bit from you, too," Luna said. "My thanks, as well."

"We need to get back to the palace," Elsa said.

"Sadly, yes. Are you ready for the teleport?"

Elsa stood and turned in a full circle, scowling. "Can you teleport me straight to my chambers?"

"No, I must return us to the kitchens. I haven't been to your rooms, so I can't hit them safely."

"We can't go to the kitchen! I'll have to walk clear across the palace."

Luna frowned. "I... I don't understand."

"The wind blew away my nightie and panties."

Luna stood, tapped her chin in thought, then smiled and flared her wings high. "Your chambers have a balcony. Elsa, do you know how to ride... bareback?"

Elsa smiled in return.
