Luna, having just raised the moon over Equestria, sat in her bedroom reading a history book she had taken an interest in. One thousand years of history was a lot to catch up on and while she had been given a broad overview of all the important parts, she liked digging into particular historical events to learn more about them in her spare time.

Her reading was suddenly interrupted by a knocking on the door. “Yes?” she asked, a frown on her face at the distraction.

“Luna? Are you free right now?” a voice she instantly recognized asked. A smile returned to Luna’s face; she was always happy to spare some time for Twilight Sparkle! “I have a bit of an… odd request for you…” Twilight continued from the other side of the door.

That put a slight crimp on her smile. What kind of request could she possibly have? “Of course, Twilight, please come in,” Luna answered as she closed the book she had been reading. Whatever it was, she would do her best for the mare who had helped save her and was now a fellow alicorn.

The door opened and Twilight stepped inside, quickly closing the door behind her as she did. “This may sound a little odd, Luna,” Twilight said as she walked to her, “but I was wondering if…” she fidgeted for a moment. “Luna, would you eat me?” Twilight finally asked.

Luna stared at Twilight in surprise for a moment, then let out a chuckle. “Is that all? And why would you want me to eat you?”

“Well…” Twilight started, “it’s just, every pony I’ve eaten, I always ask them what it was like and they all tell me how nice it feels!” she said. “How getting squeezed down my throat is like a massage. How sitting in my stomach is like a relaxing sauna; they all tell me the same things! And now I want to experience it for myself!”

Luna noded her head. “That is certainly understandable. Twilight, I’d be happy to devour you.”

Twilight’s face lit up. “Really!?”

“Yes, really,” Luna said, smiling at the younger alicorn’s excitement. “Though I must say I am surprised that you did not ask Celestia to do this instead.”

“Oh!” Twilight said, her ears folding back slightly. “I… actually did ask her earlier today…”

Luna raised her eyebrows. “Oh? And she said no?”

Twilight merely noded in response.

“I see. And did she give a reason for not wanting to?”

“She said she was already scheduled to eat somepony tonight, and wouldn’t have room for the both of us…”

Luna shot Twilight a disapproving glare. “And you really believed that?”

Twilight ears folded flat against her head. “W-what?”

“Remember, Twilight, we only started devouring ponies again after Tia had swallowed Pinkie Pie who had already eaten Rainbow Dash,” Luna replied, a stern edge to her voice. “It should be obvious to you that she has the capacity for two ponies, and I know from personal experience she can handle at least three.”

Twilight looked down at her hooves, a thoughtful look on her face. “You’re right... How didn’t I think of that?“ She looked back up at Luna. “But why would she lie about something like that?”

“Because,” Luna said, her expression turning serious, “she’s afraid of a repeat of what happened last time she tried devouring an alicorn.”

Twilight’s eyes opened wide. “What?”

The corner of Luna’s mouth curled upwards into a smirk as she levitated a cushion towards Twilight. “You should make yourself comfortable, Twilight, I have a little story to tell you.”

As Luna expected, Twilight’s face lit up with a huge grin. “This happened thousands of years ago,” she started as the purple alicorn laid down on the cushion, “when Celestia and I were still young. We had only recently discovered this ability of ours to devour ponies and regenerate them afterwards, and-” She paused as she noticed Twilight had one hoof raised in the air. A smirk crept onto her face. “Yes, Twilight?”

“Just how did you discover you could swallow ponies whole and learn Spirit Reformation spell?” Twilight asked. “I can’t imagine there wasn’t some… trial and error involved…”

Luna gave a knowing smile. “I’m afraid, Twilight, that that is a story for another time. You’ll have to ask Celestia about it someday, she knows it better than I do.” Luna ignored Twilight’s crestfallen look as she continued. “Anyway, we had only recently discovered this capability of ours, and had each devoured and brought back more than a few ponies. It should come as no surprise to you that we soon started desiring the same thing as you do now: to experience the process from the other side, as the one being devoured. We decided that we would eat each other and, after drawing lots, I got to go first!”

Luna’s eyes closed in reminiscence. “It really is as delightful as they all say, you know. Being squeezed down Celestia’s throat, her muscles squeezing and pulling at me from every side… and her belly! I have experienced few places more comfortable!”

She opened her eyes and looked back at Twilight, her face now dead serious. “Sadly, our little experiment very nearly ended in disaster. It was only when Celestia attempted to bring me back that she discovered that the Spirit Reformation spell is immensely more difficult to cast on an alicorn than it is on a normal pony.”

Twilight’s eyes slowly widened in shock. “You mean…”

Luna looked down to the floor. “She almost wasn’t able to bring me back in time, Twilight. She only barely got the spell off at the last possible moment before I would have been gone from this world for good.” She looked back up at Twilight. “She very nearly killed her own sister.”

Twilight stared back at Luna, mouth hanging open in shock. Silence held the room for a few moments before Twilight finally spoke. “Goodness… I never would have guessed… So that’s why she wouldn’t eat me? Because she’s-”

“Afraid,” Luna finished for Twilight. “She’s afraid of the same thing happening again. She doesn’t want to risk losing you, Twilight.”

Another long silence descended upon the two as Twilight looked down at her hooves, absorbing this startling revelation. Finally, she looked back up at Luna. “But… you just said that you’d eat me… so you don’t think that would happen again?”

Luna gave a reassuring smile. “Twilight, not only are we much, much more powerful than we were back then, but we are also much more experienced with the Spirit Reformation spell. I am absolutely certain that such a thing would not happen again.” She nodded to herself. “Worst case scenario, I might require Tia’s help to cast it, but I see no way that we would not be able to bring you back. So, do you still wish for me to devour you?”

Twilight hesitated only a moment before nodding her head. “Yes. if you say you could bring me back, then I trust you.”

Luna stood up. “Very well, then. How do you wish for me to eat you?” she said as she turned towards her bed.

Twilight, seeing what Luna had planned, hopped up onto the night alicorn’s bed. “Backside first, please,” Twilight said as she laid down with her rump at the edge of the bed, her tail tucked underneath her body in the customary position. “I want to be able to watch while you swallow me. And take it nice and slow, too, I want to get the full experience!”

Unseen by Twilight, a mischievous smile crept onto Luna’s face. “The full experience, you say? Very well, I shall endeavour to make this as enjoyable as possible for you.”

Twilight was about to ask what exactly Luna meant when she suddenly felt her tail yanked out from under her and pulled straight up, leaving her backside fully exposed. Twilight gave out a startled yelp as her face suddenly turned red. “Luna!? What are you- ooohhh~” she broke into a moan as she felt warm, moist air wafting against her nethers. She glanced back to see Luna’s face peeking up over her plot, meeting her stare.

“You did say you wanted the full experience, did you not?” Luna said with deeper, sultrier voice than normal causing Twilight to let out another quiet moan as her words caused more of her warm breath to wash over the purple alicorn’s nether lips. “If this is not what you want, simply say the word and I shall devour you in a more conventional manner.”

Twilight looked back at Luna for a few moments, panting slightly, heart racing. While this certainly isn’t what she had been expecting, she also couldn't deny that she found the prospect before her enticing. She, like most ponies, had always found both Luna and Celestia to be ideals of beauty, and while she couldn’t imagine herself engaging in such activities with Celestia, who was like a second mother to her, the thought of being with Luna…

She felt her clit involuntarily wink and her wings starting to stiffen; her body seemed to have made her decision for her. “No, keep… keep going…” she finally said.

Luna smiled back at her. “As you wish,” Luna said, then opened her mouth wide and plunged forward.

“Aaaahhh!~” Twilight yelped as Luna literally engulfed her cunt, the feel of the elder alicorns soft, warm lips completely surrounding her nethers. She then let out a loud moan as Luna’s tongue lept into action, tracing the outside of her snatch before plunging inside.

Twilight pushed her face down into the bed to muffle her moans as the alicorn of the night showed her an amount of pleasure she had never felt before. Her tongue seemed to be everywhere, the broad, muscular organ traveling deeper inside of her than she would have thought possible. She was so focused on the intruder inside of her that she was only vaguely aware of Luna lips slowly creeping outwards over the rest of her backside, the entirety of her nethers being engulfed in the warm, tight, wet confines of the blue alicorn’s maw.

Twilight’s wings were opened painfully wide as she tried catching her breath between heated, throaty moaning. It wasn’t very long at all before things came to a head. “L-Luna! I-Ah!~ I’m… I’m going- OOOHHH~” The smaller alicorn convulsed on the bed as she came, her inner walls clenching around the thick organ thrashing about inside of her. After what seemed to be forever but was really less than a minute, her orgasm finally came to an end. She lay there on the bed, panting heavily to catch her breath, her body covered in sweat. “Goodness…” she finally said, “That was amazing! Where did you learn to do that?”

Twilight looked back at Luna, only to find the elder alicorn’s mouth stuffed with Twilight’s flanks, only part of her starburst cutie mark still visible, Luna’s cheeks bulging outwards. Luna’s only response was to raise an eyebrow. “Right,” Twilight said, “can’t really talk right now, can you?” She looked forward and rested her head on the bed again. “Thank you for giving me the ‘full experience’, Luna, but I think I’m ready to experience the rest, now.”

Twilight heard a muffled “Mhm,” from Luna as confirmation, then heard a loud GLURK and gave a startled yelp as she was suddenly yanked backwards a few inches. “Ooohhh~” Twilight moaned, “it really is like a massage…” She closed her eyes to focus on enjoying the feel of Luna’s throat undulating around her body, tugging and pulling her deeper inside. Each noisy gulp sent a muscular ripple along her flesh, the peristaltic action squeezing and tugging at her body. Combined with the moist warmth, Twilight felt like she could just melt. “Oh yeah…” she mumbled to herself, “this feels amazing~” It was enough to make her practically comatose; she wanted nothing but to just lie there and enjoy the feeling of those throat muscles working over her body. She was barely aware of Luna using her magic to fold her wings back against her body so she could get them into her mouth.

She was shocked out of her stupor when Luna, having swallowed Twilight up to her shoulders, suddenly craned her head upwards, lifting Twilight up off the bed. “Wah!” Twilight cried out. “Luna, give a mare a little warning next time!” she said, but was quickly distracted when she noticed how much Luna’s throat was bulging outwards. She had watched the other princess devour other ponies before, so seeing their throats stretched out like this was nothing new to her. But this bulge wasn’t some other pony, this bulge was her. She found herself unable to look away from it, and when Luna swallowed again, Twilight could see the ripple move down her neck as she also felt it.

Luna slowed down her swallowing, letting gravity take over some of the workload, allowing Twilight to slowly sink down under her own weight, dragging out the experience for her. But all too quickly for Twilight, she was forced to tear her gaze away from the bulge she was making in Luna’s threat as she sunk down far enough that she was forced to tilt her head back. “Thank you so much for doing this, Luna,” Twilight said as her field of view became constricted by those blue lips, her forelegs forced up into the air above her. Another gulp and Luna shut her lips closed around her forelegs, plunging Twilight into darkness. Luna’s tongue licked over her face, and in an impulsive fit of playfulness, Twilight licked her tongue back. That earned her a surprised hum from Luna making the alicorn’s entire throat vibrate around her, much to Twilight enjoyment. Then another loud GULP finally pulled Twilight’s head down into her throat.

Twilight closed her eyes to better focus on the sensation around her. If Luna’s swallowing was noisy before, each gulp now positively thundered in her ears. She suddenly felt her hind hooves bump up against a fleshy barrier. She knew exactly what is was: the entrance to Luna’s stomach. Another resoundingly loud swallow and that barrier gave way, allowing her hind legs into a much roomier space just as the tips of her forehooves were finally sucked down into Luna’s mouth. She was finally completely inside Luna, her entire body, from hoof to hoof, squeezed and caressed by soft, warm flesh. She hummed to herself is satisfaction as each swallow pulled her farther down as it caressed and kneaded her. She suddenly felt something pressing against her from the outside; she knew it had to be Luna, rubbing the bulge in her neck. It was all almost too much for the young alicorn, the myriad of novel, enjoyable, relaxing sensations enough to make her never want to do anything again.

More of more of her squeezed past that fleshy barrier into Luna’s stomach, one last loving hug from Luna’s throat before being deposited into the roomier stomach. It was no less comfortable, however; now that she was done with her full body massage, she had room to stretch a bit and relax. And that’s exactly what she did, stretching out her limbs, pushing her hooves against the soft, squishy walls of Luna’s stomach.

“I take it you enjoyed the experience, Twilight?” Luna asked, her voice reverberating all around Twilight.

“Mmmmmm~ It was wonderful, Luna!” Twilight replied, pressing a hoof against the side of the stomach. “Thank you so much again for doing this!”

Twilight felt something push back against her hoof from the outside. “Of course, Twilight, it was my pleasure.” There was a short pause. “I mean that quite literally, too; you were quite delectable!”

Twilight giggled. “Glad to hear it, Luna!”

“Here, let me enhance the experience some more for you,” Luna said, then Twilight felt her start rubbing her belly.

“Mmmm~ That feels great, Luna…” Twilight said. Such soft, warm confines and with Luna pushing and kneading against her just the right amount, it was enough to put a mare to sleep! Twilight soon noticed another stimuli, a rhythmic beating noise. Thump-thump, thump-thump. It took Twilight’s drowsy mind a moment to identify it; it was Luna’s heartbeat. The myriad sensations all seemed to blend together as Twilight lost all track of time, all conscious thought melting away into nothing.

She had nearly fallen asleep, when she was roused slightly by a shifting of her enclosure. Luna must have been standing up. “I suppose I’d better go inform Tia of what we’ve done…” Twilight heard a voice say, a voice she barely remembered was Luna. Luna’s stomach began gently rocking back and forth as she started walking, yet one more sensation trying to relax her into nothingness. “Why do we have to tell Celestia anything…” Twilight mumbled to herself, her last conscious bit of thought before soft, wet, warm blackness overtook her.

“Twilight Sparkle, It’s time to wake up!” a familiar voice said.

Twilight groaned in disappointment at her rest being disturbed, and reluctantly opened her bleary eyes. Two forms slowly straightened themselves out as her eyes adjusted: Princess Luna and Princess Celestia, standing at the foot of the bed, smiling down at her.

“Uggh…” Twilight groaned again. “Celestia? Luna? What did I…” her eyes shot open as her memory returned to her. “Luna ate me!” she shouted, “but I’m still here, so-”

“Yes, Twilight,” Celestia said. “Luna was able to cast the Spirit Reformation spell on you with no problems.”

Twilight looked to Luna, who nodded back at her, and Twilight smiled. “That’s great!” Then she looked back to Celestia and her smile vanished. With a flash of purple, Twilight teleported off the bed and in front of Celestia, then reared up to hug her before she could react. “Celestia, Luna told me about what happened when you tried to eat her. I’m so sorry you had to go through that.”

Celestia was too surprised to respond at first, but quickly regained her composure and gladly returned Twilight’s hug. “Thank you, Twilight. It means a lot to me to know that you care so much.”

Twilight released Celestia and stepped back. “But you know what this means, right?” She asked, an excited smile on her face. When Celestia didn’t respond, she continued. “We now know for a fact that the Spirit Reformation spell works on Alicorns! That means that now we need to have somepony eat you!”

Celestia blinked. “Me?”

“Yes!” Twilight continued. “From what Luna told me, you’ve never been eaten before! It’s the best thing ever, you have to experience it!”

Celestia stared back at Twilight a moment before responding. “Twilight, I’m glad that you’re thinking of me, but I can’t just go and let somepony eat me,” she said as Twilight’s smile slowly faded. “I have much too much work to do in ruling Equestria; I can’t afford to lose two days inside somepony’s belly, no matter how relaxing it may be.”

Twilight looked absolutely crestfallen, her ears folded back against her head. “Oh… I see…” she said, looking down at her hooves.

Celestia grimaced slightly; even when Twilight was a filly, that look was always hard for her to ignore. “Tell you what, Twilight, I’ll remember to keep a few days open next time a hole pops up in my schedule, alright?”

Twilight’s face immediately lit up again. “Yes! I promise you, Celestia, you won’t regret it!!”
