“I still don’t know why we’re supposed to do this anyways…” the gray plane pony replied, slightly nervous but more embarrassed about the whole ordeal that was going to follow shortly. Her turbofans vrring idly, accentuating her emotions towards the situation she was in currently.

Meanwhile, located on top of the upside-down hoof, an engineer, and, more specifically, the lead engineer tasked with the maintenance of this plane pony, simply shrugged. “I… I don’t know… high command orders it… I guess some kind of really awkward trust exercise?” he said, idly kneading the frog he was sitting on… it was so soft… wait… how it is so soft and fluffy? “Hah… you have soft hooves” he idly remarked, coming off more as a tease than anything.

Upon hearing that sentence however, the already blushing plane pony in front of him blushed somewhat more, and she scoffed a little “If… you say that to anyone… I’ll crush you…” she spat towards the technician, giving him a cold glare, though the warning was probably not real and more product of her Tsunder-ish attitude. “Are we going to do this or not? I really want to end this as soon as possible…” the plane pony said, shortly afterwards looking away and trying to avoid eye contact with her mechanic.

“I guess so” said mechanic idly mused, fidgeting with his horn to know if he still remembered the flashlight spell, and indeed it did work, if his horn lighting up was any indication. He stood of the hoof, still slightly mesmerized of the softness of the underhoof of a plane pony literally meant to destroy all ground targets… it was… ironic how this military plone was so soft… both in the exterior and interior, though few know the former and extremely few know the latter. “Uh… you know what we have to do Blitz…” he said, pushing his little, circular glasses up his snout, the reflections of the hangar’s dim lights being the only light source that shimmered on his eyewear; the door was completely closed shut, and any other entrance too, Blitz was definitely embarrassed of the thing they were about to do and made sure nobody could see them both, heck, she even huddled in a dark corner where the light didn’t reach, just in case someone did manage to go through the armored doors.

“Yeah yeah yeah, y-you don’t have to remind me, goddamnit” the plane pony said, though her voice was breaking slightly with stuttering. She stayed silent and motionless for atleast a solid minute, the mechanic patiently waiting her… atleast until she decided to end this as quickly as possible… her mouth suddenly opening… opening wide into a big maw… the jaw dropping as much as it could, exposing her shark-like, but still snub at the tip frontal teeth… and by Celestia you didn’t know how those were called, you weren’t a deontologist… there was drool dripping a little, the red-pink-salmon flesh of her mouth visible, along with the… slightly orange-ish tongue. There were some… wait no… rather many columns of saliva… from the tongue to the roof, the mouth sides… it was rather… in…inviting…

The mechanic, still at the plane pony’s hoof, blushed deeply, he now was wondering why he was doing this, the mouth of his best friend plane pony exposed and the dark, but… oddly comfy-looking insides being visible… he could even see her uvula…. And right behind that the 30mm GAU-8 rotary cannon… he idly wondered how that cannon worked with all that saliva.

A quick look towards the face of his friend made her realize her whole appearance… and he actually felt bad… she was sweating heavily… blushing reaching the upper part of her snout and her ears, her unsure and embarrassed eyes showcased the emotions that she was feeling. Some kind of background noise coming for Blitz that he couldn’t quite recognize reminding him that this was super embarrassing for her

“Nice maw” he still said amidst his blushing, the plane pony slightly changed his facial expression and looked at him with a mildly stern face “S-shut up you asshole…” she said, looking away slightly. The mechanic giggled a bit at her disposition, sure she was Tsundere…

“Alright… I’m going in… hope you find me tasty!” The mechanic just teased towards his plane pony friend, said friend regretting more and more about this and spitting back “Do you want a 30mm DU shell up your arse? J-just shut the fuck up already…”, it was clear that she tried her best to be as intimidating as she could, but in fact she wasn’t going to do that to her friend, and both knew it.

Soon, the plane pony brought her hoof closer… and closer… towards her open mouth, the O shape vaguely reminding the technician of a tunnel of sorts… just that this tunnel was fleshy, hot, wet and belonged to a giant pony… He stepped closer , her breath washing over him a little, but he just adjusted his glasses and continued.

She pulled out her tongue, driplets falling from it towards the hard, cement floor beneath the plane pony’s hooves, even her tongue told the mechanic she was embarrassed. “Um… just… don’t worry…” he said, trying to make his plane pony friend feel better, it seemed to mildly work as the hoof that transported him moved quicker, the frog touching the lower section of the tongue.

“Careful you don’t fall…” the plane pony said, knowing that she was a giant and such micro pony falling off that height wouldn’t be good. The soldier simply said “Oh, you worry about your meal falling off to the ground?”, it was a teasing move, but he actually just wanted to make the ambience a jokingly one and try to erase the embarrassment of this.

“I-I care about you, idiot!” she said, and it was true. The mechanic nodded and went inside… to her mouth… his hoof stepping on the tongue and almost immediately getting damp, shortly afterwards wet by the saliva that dripped of it… he put the other hoof on, and after a while, his whole body was resting on the tongue. He tapped twice her tongue and the plane pony receded the warm muscle back to his cavernous origin.

Soon, the plane pony realized that the soldier had already entered her mouth, and she slowly closed it, making sure not to crush any bodypart of his or hurt him in any way. She dared not to talk, to avoid both making this more uncomfortable and making the technician (Who was already in an unsteady position with all the wetness) fall from her tongue or something.

For the soldier, it was a rather new… and… curiously nice experience… the upper pallet somewhat squeezed him against the tongue, so he was pretty much laying on the latter like a makeshift organic mattress. He’s awash with warmth as the plane pony breaths and her innards. All around him there was wet, only wet with saliva; he doubted that any part was actually dry. He adjusted against his glasses and saw around, using the light spell to illuminate his view. The drool rained down upon him, soaking his whole furry body with saliva, the tongue slightly pushed him against the ridges of the palate, squeezing him tightly, but he wasn’t being hurt… he didn’t feel any pain… it was actually an extremely nice experience…
Suddenly, he felt how the tongue pressed his body downwards and forwards, forcing the mechanic’s body to go forward too… He was being moved towards the throat as he suddenly saw the usually sealed flesh opening like some kind of valve, he just took a large breath, imagining this might get awkward, as he fell right on it, the flesh suddenly tugging his whole little body down with a single, but big contraction.

The esophagus, that was like a really tight tunnel like place, guided his way downwards his destination, the walls of the tube constricting him, but rather gently, he gasped a little and got a bit shocked when he realized he could breathe… how he did was beyond him, considering he was sealed in the plane pony’s esophagus, but still, it was a nice surprise, he breathed slightly heavily, as the flesh rippling proved gentle in their contractions, the walls coating him whole and thoroughly with saliva, whatever part was dry before was now wet, he could listen some kind of thing pumping, you weren’t sure if it was her heart, or she actually had a heart… biologically speaking… but still…

Eventually, his little body was pressed tightly against an end of the road, the technician lying down in the whole process as he was being smothered against such thing that dared not to receive him, it was kind of curious how he still didn’t feel hurt at all… sure, he was being squeezed whole… but it felt more soothing than harmful… In any case the thoughts about the comfyness of his friend’s throat were interrupted as a second valve in front of him opened, the tiny soldier being squeezed thoroughly through the opening.

He fell down slightly unceremoniously, then again, he was literally sliding on a stomach, there was literally nothing ceremonious of that. His body landing with a splat along the floor, the skin and muscle being… soft… really soft… it was actually quite cushy… the soldier crawled a little, some kind of slime that felt warm to the touch coating him thoroughly, he giggled a little as he again passively lied down on the comfortable surface, nothing was burning, or stinging, or tingling… nothing was harmful… it was just… safe…. And nice…

The stomach walls, suddenly having realized that there was a new visitor to their realms, gurgled and growled in happiness, contracting softly but firmly around the plane pony’s friend, the folds of muscle squeezing, squishing, and smooshing him harmlessly between each other, moving and gently grinding his tiny body, it felt… like an odd, but relaxing and soothing massage… the occasional gurgling and grumbling of the stomach becoming a comfortable white noise for the mechanic, and the warmth emanating from it being… just perfect… not too hot or not too cold, the giant pony’s meal couldn’t help but purr happily in delight at the… honestly awkward but also… delightful experience. He had thought some time ago while on the esophagus that he was going to get digested or something similar that might hurt him… but so far it has been a wonderful moment… at this point he didn’t fear anything and loved everything.

The plane pony, feeling the mechanic inside her belly, uttered a silent and even timid “W-why… why this…felt so nice?” completely confused about the whole ordeal… she… she just ate her friend like some kind of snack… and it felt kinda nice… she couldn’t help but idly smile a bit at the experience, as she started liking this ‘Vore’ thing… The mechanic, having heard her sentence, uttered a soft “I… I have the same question…”, replying her.

“Well… uh… I… hope you like it? When you want me to let you out?” The plane pony asked towards herself, anyone could’ve thought she was going insane and talking to herself, but she was actually just talking to her stomach content’s… which makes just as much sense as talking to oneself…

“Um… I don’t know… I don’t mind staying in here while you sleep…” the mechanic idly said, his blushing invisible to the plane pony but still his giant friend could know very well he was embarrassed “Uh… sure then… don’t talk this to anyone or I swear to Concorde that I will murder you” the plane pony said, slightly sternly, it was clear she wasn’t being serious, but she still wanted to keep this a secret. The mechanic just said “Sure, don’t worry”, his words being truthful that he wasn’t going to spill the soup anytime ever.

Soon, the stomach started moving slightly, as the engineer assumed it was the plane pony walking towards her bed, he could barely hear her yawning slightly as she approached her resting place…
…Little did the mechanic know… that Blitz enjoyed this exponentially this whole time… accentuated by the fact that she was the one squishing her friend in her belly both because she liked the experience herself and wanting to give him a nice experience too…

…The plane pony smiled, looking at the place where her belly was, and just closed her eyes, a thought going over her head that wondered when they would do this again, atleast until she fell asleep herself, her… ‘snack’ following suit deep inside her, napping and enjoying this together…
