Part I : The Silver Shoals

~ 🌙 ~

Wednesday, May 2nd, Year 3 of Princess Twilight

Marble woke up in an unknown, but incredibly comfy, bed. Groggy, she squirmed a little, trying to get her bearings. Slender, dark blue legs, wrapped from behind around her neck and barrel, tightened their grasps on her body, pulling Marble into a warm embrace. With a start, she realised she was being hugged by Princess Luna, the sleeping alicorn tenderly nuzzling her long mane.

Marble tried to pull herself free, but to no avail. She was strong — after all, she was an earth pony and she crushed rocks for a living — but Luna’s legs were unusually powerful. Marble could have probably bucked the alicorn harder, but she wasn’t that desperate, regardless of how bizarre the situation was. With a sigh, she accepted her fate as a princess’ living pillow for the time being.

Minutes dragged on in the still bedroom, Marble thinking about Princess Luna. It was… odd, to say the least, to be cuddled like this by an ageless alicorn. As a foal, Marble had heard — like everypony else — the legend of Nightmare Moon; the concept that the kind, witty mare that had called her ‘friend’ was that same dastardly villain, reformed after a thousand years locked on the Moon, was difficult to wrap her head around. Luna’s hug was gentle, comforting: a relaxing experience.

That is, until the princess bit her ear.

Marble gasped, then moaned. Luna’s teeth, gently clenched around her pointed ear, brought delightful sensations that coursed through her body like a wildfire. Her hindlegs twitched.

"L-Luna!?" There was no response: the princess was still sleeping, even drooling a bit in Marble's mane.

As Luna kept suckling her ear, Marble's clits winked. Eyes wide, she felt her vulva flush with blood, growing moist with her natural lube. She blushed, turning crimson with embarrassment. But she couldn't help it; her body had longed for another pony's touch for so long, and Luna was providing, albeit unconsciously. Marble felt dirty, like she was abusing Luna, enjoying her touch like this. Feeling very guilty, she dipped her hoof in her wet folds. She couldn't hold back her moan.

Luna woke up, Marble's ear still between her lips. It took the alicorn a few seconds to understand what was going on.

"Aaah!" Luna pulled back in a flash, taking her hooves off Marble's body like she had burned herself. "Sorry-sorry-sorry! Oh, I am so sorry, Marble! I… I did not… I did not mean to… to do this!"

Marble panted, shame mixing with the awful ache of having been denied release. She looked down, trembling, not meeting the princess' gaze.

"I, uh… I had not wanted to disturb your rest, so I let you slumber in my bed… I must have held you while lost to my dreams," Luna explained shakingly. "I cannot apologize enough; I did not wish to make you uncomfortable."

"I, um, need to go to the toilet." Marble left the room in a hurry, locking herself in the bathroom. She sat on the bowl, starting to sob as she emptied her bladder. Her morning business done, Marble flopped down on the cold stone floor.

Marble mashed her hoof between her legs, trying to masturbate, but she couldn't do it. She was a horrible, no-good, lewd pony who had betrayed her princess' trust.

A few minutes later, Luna knocked on the door. "Marble? Are you okay?"

She didn't respond.

"Marble, may I come in? Please…"

Still no answer. Blue magic surrounded the doorknob, unlocking it. Carefully, Luna peeked inside, finding Marble on the bathroom floor, staring blankly at a wall. The princess lay down next to her, close but not quite touching.

"I'm so sorry, Princess…"

"What for? It is I who must apologize. As I have said, I did not want for you to be uncomfortable."

"No… it's not that…" Marble let out, fidgeting with her hooves. "It felt good, so good. I shouldn't have…"

"Oh…" Luna draped her wing over Marble's back. The gray mare leaned onto the princess, finding comfort in the alicorn's warmth. A dark blue hoof gently stroked her mane. "Marble, do you remember that dream?"

Marble nodded. It was faint in her memory, but what had led to it was crystal-clear.

A few years back, shy little Marble Pie had met a stallion who seemed perfect for her, a big red workhorse who didn't talk much either. She'd kept thinking about him, imagining making love with him, carrying his foals and raising a family. A couple years later, day for day, she had met him again, and she had seen him kiss his wife under the mistletoe, breaking Marble's heart. Princess Luna had appeared in her dream that night.

"You… you told me that, one day, I'd find the pony that would be just for me. You said that he'd be lucky to be with a mare like me."

"Did you?"

Marble shook her head, tears threatening to flow.

"I… I did not know."

"And… and then, you made me feel… but you were sleeping, and I… I shouldn't have… It wasn't right."

Luna embraced her. "It is alright. It is wholly natural to want to feel such things, to feel somepony else's touch. I take no offense. Would it help if I helped you climax?"

"Uh? You… You'd do that? With me?"

Luna nodded, a kind smile on her face. Lost in the princess’ eyes, Marble murmured a throaty 'okay', giving her consent. Luna's hoof ran along her back, gently moving down toward her rump. Instead of going even lower, it moved back up, rubbing Marble’s back.

The princess kept doing this for several minutes, letting Marble relax. Eventually, Luna’s hoof wandered down her thigh, approaching — but not quite touching — Marble’s flushed marehood. “Should I go further?” Luna whispered, slowly stroking Marble’s butt.

Marble looked up at Luna, the alicorn lying at her side on the bathroom’s floor. She lost herself in her gentle eyes again, soothed by her reassuring smile. Everything would be fine. “Please…”

Not breaking eye contact, Luna slid her hoof under Marble’s tail. The young mare felt it dip between the lips of her vulva, tenderly parting them. Marble let out a tiny gasp, burying her face in her forelegs as the princess stroked her most intimate place, soaking her royal hoof in her fluids. Marble tensed, her vagina clenching as she was pleasured by another pony for the first time. Luna ran little circles over her marehood, slowly, carefully masturbating the smaller mare.

Luna’s slick hoof moved up a tiny bit, tenderly rubbing the pert rim of Marble’s tailhole, making her moan softly at the illicit touch. Luna soon moved back to Marble’s vulva, caressing her winking clit.

Princess Luna licked Marble’s ear, murmuring, “Faster?”

“Mmhmm…”

Luna’s hoof pressed harder in her slit, picking up speed. Marble squirmed in delight, waves of pleasure radiating through her body. She looked back up to Luna, her mouth open as she panted for breath. There was a gleam in the princess’ blue eyes; both mares’ eyelids closed of a common accord, Luna pressing forward to meet Marble. Their muzzles met slowly, their lips melding together.

Marble felt Luna’s tongue slip in her mouth, and she welcomed it with her own, her saliva mingling with the princess’. They made out tenderly, sharing a deep, delicate kiss, Marble moaning softly as Luna masturbated her.

They parted a few inches, a slim strand of saliva linking their lips. Luna rubbed Marble’s pussy harder, faster, bringing her toward an orgasm more wonderful than she’d ever given herself. Marble gazed at Luna, the alicorn face flushed with excitement, the earth pony taking in the beautiful sight of the mare giving her such pleasure.

"Ngh… Aaaah!” Marble arched her back, her fluid gushing from her vulva, coating Luna’s pastern and cannon with her pleasure. Her vagina clenched hard around nothing as she came, seeing stars. Luna held her close, rubbing Marble’s pussy deeply, prolonging the young mare’s climax until she couldn’t take any more.

Marble went limp in Luna’s embrace, the alicorn removing her hoof from her vulva before her pleasure turned into discomfort. They stayed like this a while, neither mares saying a word as Marble recovered from the orgasm she had just experienced. Fascinated, she saw the princess lick her own hoof, tasting Marble’s snatch and not letting a drop go to waste.

Luna gave Marble a kiss on the cheek and rose from the bathroom’s floor, helping her up.

“Did you like it?” Luna asked, a cute blush on her cheeks.

“L-Luna, I… I don’t know what to say. Thank you. That… That was wonderful.”

Princess Luna nuzzled her mane, whispering, “I loved it too.”

“But, uh… you, uh… you didn’t come too. Shouldn’t I… you know, help you too?”

“Perhaps another time,” Luna replied kindly. “Do not worry, you needed satisfaction, and I was happy to give it to you.”

‘Another time’? Does she mean… Marble shook her head, clearing her thoughts. She was all sexed out for now, and she had other matters to take care of. “Luna? I’m pretty hungry… Do you have something for breakfast?”

Luna grinned. “Would you help me prepare it?”

Marble smiled in return.

“Are you sure? I love your place, but the hotel is fine.”

Luna waved her hoof dismissively. “Of course! I so seldom have the chance to entertain guests in my home.”

“Well… okay! I’ll go pick up my bags and give back the key!” Marble trotted inside the lobby, a little excited bounce in her step.

They had spent the entire day again in each other’s company, the hours flying by as they enjoyed everything (that wasn’t too extreme or crowded) that the Silver Shoals had to offer. As they shared dinner yet again, Luna had offered Marble stay at the Eventide Cottage for the duration of her vacation.

Marble left the hotel a few minutes later, her back loaded with a pair of saddlebags. “Okay, that’s everything. I suppose we should go back to the cottage and drop this?”

“That will not be necessary. Here, let me.” A blue glow enshrouded Luna’s long, elegant horn, and Marble felt the weight on her spine vanish with a fwap. “There, I sent your bags ahead. If you do not mind, I have something I would like to see. Do you wish to accompany me?”

“Oh… well, sure. Why not?”

Luna led Marble out of town again, bringing her to the base of the great cliffs. The tide was high, and the ocean battered the rocks beyond the beach. They jumped from rocks to rocks, making their way as the seabreeze caressed their manes, the last glow of daylight guiding their steps.

Luna eventually stopped in her tracks. “It is here,” she said, pointing a hole large enough for a pony to pass through, halfway up the cliff.

Marble looked at the cave entrance, perplexed. “This? But, how do we — “

Luna flapped her wings and soared high, doing a great loop before gliding back toward Marble. The earth pony saw the princess’ shining horn and her amused grin; in a flash, she understood what was about to happen. Luna swept past her, a blue glow surrounding a wide eyed Marble.

“Waaaahaaa!” Like she’d been grabbed in a giant, invisible talon, Marble lifted off the ground, soaring screaming after Princess Luna. The alicorn spread her wings, slowing herself down, then flapped to stabilise her flight near the entrance of the cave. Marble floated in front of her, her heart thumping in her chest like she’d galloped a hundred miles.

Luna flashed Marble a wicked grin. “How is this?”

Marble was panting hard. “Ah… hah… ah… ahah… ahahahah… HAHAHAHA! HAHAHA! Hehehe, hahaha! That… That… ahaha! That was AMAZING! Again! Hahaha!”

Luna busted out laughing too, making Marble do a few loops around her. “Okay, okay… ah…” the princess let out as she calmed down a little. “I am pleased you like it. Perhaps we can do this again another time? I still want to see inside this cavern.” She landed into the dark opening, depositing Marble on the smooth ground next to her.

Lighting up the way with her horn, Luna descended into the passage, a curious Marble Pie on her tail. The path followed a gentle downward curve into the earth, smelling of seaweeds and saltwater.

The cavern was probably of natural origin, Marble thought as she observed the rock walls, but the tunnel’s width and smoothness told her it had seen heavy use sometime in the past. Generation of ponies — or other creatures — had once stepped in this now silent place. As if to confirm her suspicions, Marble spotted faded engraving along the walls, depictions of sea motifs and animals.

“Luna? What is this place?”

“Nopony knows. It is older than I am. Does this darkness unnerve you?”

“No, not really. There are a lot of caves and old mines near my family’s rock farm, and I often go in to search for rare minerals.”

“I see,” Luna said. “This place should be safe. Ponies sometimes come here from the town, and I have been too.”

“Oh. Why come now, then?” Marble asked.

“I wish to put a rumor to the test. You shall see soon.”

The passage leveled out and expanded. The light of Luna’s horn revealed a large, mostly circular chamber with a ceiling sporting strange, primitive bas-reliefs. A large, deep pool of seawater covered much of the cave’s floor, while the rest of the surface was composed of soft sand.

Luna approached the dark waters, observing the still surface. With a flash, she teleported a small object in front of her and held it in her hooves.

“Isn’t that the stone I told you was a real gem, when we met in the antique shop?” Marble asked, recognising the dark blue stone.

“Mmhmm. Thank you again for your help. I have been wanting to test this for a while.”

“Uh… what’s going to happen?”

“I am not sure, but it should be safe.”

Not entirely reassured, Marble stepped back behind Luna. Without ceremony, the princess tossed the gem into the pool.

Plop! The sound echoed throughout the cave, breaking the deep silence. For a long moment, nothing else happened.

A small glow appeared beneath the water’s surface, soon followed by several more. Luna extinguished her magic, the many-hued aura of the pond projecting a slowly shifting kaleidoscope upon the chamber’s ceiling. The princess knelt down next to the pool, Marble settling down at her side.

Peering into the glowing water, Marble saw hundreds of luminescent fish slowly circling around, lighting up a passage that went much deeper under the clear water.

What was going on? Marble didn’t know, and Luna didn’t either. They simply observed the gentle, peaceful spectacle of these glowing fish in their subterranean haven. Marble felt like there should be some strange, otherworldly music, but the cave was silent.

Marble leaned into Luna’s side, the alicorn’s wing wrapping over her. “This is so beautiful, Luna,” she murmured, feeling the relaxed pulse of the princess’ heartbeat beneath her dark blue coat. Luna nuzzled Marble’s mane.

Looking into Luna’s gaze, Marble saw that same heated gleam she had already seen in the princess’ eyes. She wrapped her forehooves around the taller mare’s neck.

They kissed, slowly, softly, deeply. Their tongues entwined, and they explored each other, making out on the cave's soft sandy floor. Luna ran her hoof through Marble's silky mane. They prolonged their embrace for what felt like hours, finally parting only as they had to in order to breathe. They rolled on their back, watching the light show above as they caught their breath.

Without a word, Luna embraced Marble again, and their lips met once more. They shared a series of short, playful kisses.

Marble's excitement grew as she felt Luna's hoof venture down her belly. She moaned into the princess' mouth as the dark blue hoof lovingly parted the lips of her engorged slit. Marble cooed as she was once again masturbated by the Princess of the Night. Pressing her body closer, Marble let her own hoof wander down Luna’s slender barrel.

There were no protests from the princess, just approving little moan as she rubbed Marble’s flushed sex, so the young mare explored between Luna's hindlegs. She felt something plush, warm and wet: Princess Luna's vulva. The alicorn twitched as Marble began to pleasure her in return, both mares moaning and cooing in shared pleasure.

Marble pressed harder into Luna's soft pussy, watching her squirm in delight. She wanted, needed to see her friend's pleasure, to see the princess orgasm under her touch, to have her climax because of her.

Their mutual masturbation grew increasingly desperate as they approached the peak of their pleasure, both mares trying to get the other off with frantic intensity.

Marble, however, didn't stand a chance against Luna's centuries of experience. The princess' hoof skillfully rubbing her clit, the young mare climaxed, her panting gasps of delight resonating in the underground chamber. She didn't let go of Luna's marehood, though, and she stroked the aroused labia in a frenzy.

Coming down from her peak, Marble met Luna’s heated gaze, seeing the passion burning in the alicorn's twitching body. Determined to see her climax, Marble stroked Luna's winking clit. The princess bit her lip, looking like she was about to cry, and buried her face in Marble's neck. The younger mare embraced her tightly, her hoof giving her the last few strokes she needed to go over the edge.

"Mmmmh! Hmmm!" Luna tensed, her vagina clenching. Trembling, she came in Marble’s embrace.

Marble felt something warm gush from the alicorn's snatch, coating her hoof with slick mare fluids. She kept gently rubbing Luna's pussy, prolonging her orgasm for as long as possible. Eventually, Luna pulled back slightly, signaling that she had enough, so Marble let go of her sex.

They stayed like this a long time, embracing each other on the cave floor, the evershifting multicore glow of the pool lighting up the scene. Slowly, the light ebbed, and the cavern returned to darkness. Luna lit up her horn again. "This… This was wonderful, Marble. I… I have not… I have not felt something like this with anypony else in a very long time."

Marble looked down, a deep blush on her cheeks. "Um… I never… felt like this… for a mare. I… I didn’t think I could like another girl, just like… you know, like a stallion. But, with you… it's…"

"Would… Would you like to share my bed again tonight?"

Marble sighed, hugging Luna. "Yeah… yeah, I'd like that."

They made their way out of the mysterious cave, Luna taking Marble for another flight back to her cottage.
