Applejack, after a few minutes beneath whatever she was sunk in, realized that she hadn’t breathed in a while. Oddly, that didn’t feel bad, and for a moment, she wondered if she might have died, but a quick check of her body told her nope, her heart beat was strong, so she was still alive. That seemed odd, and so she tried to make it to the surface again, slamming once more into some solid wall and trying to let her body raise her upward again.
This time it worked, probably because she’d been rising slowly, and had just been deep in whatever she’d splashed into. With her at least breaching the surface she took one long deep gasp of air, filling her lungs with the sweet taste of the gas around her. Mind, sweet taste was right, as she looked about her, realizing quickly that the tickling feeling she’d been having under water…under liquid, wasn’t just her imagination, as all around her bubbles came to the surface of the stuff, popping and creating quite the ruckus of sound, and belching sweet tasting gas into the air.
Trying to focus over the sounds she was hearing, Applejack began to take stock of her situation. She had no idea where she was, since Rainbow Dash had let her fall to her doom, and even looking around told her nothing. There were high, straight walls that seemed to be made of fibers woven tightly together, too tight to use for traction to climb out. Contained in those walls was the bubbling liquid, and herself, incidentally. There did seem to be some kinda pole thing in the center of the lake of stuff, but since it was almost as wide as she was around, it was useless for getting out.
Applejack of course, screamed for help, as she had no idea where she was, but considering how loud the bubbling sound was, she doubted anypony heard her. She heard them though, if only barely, voices outside, one sounded like Twilight, and the other…she couldn’t place, but it was familiar, and probably meant Rainbow had somehow followed Twi, and dragged AJ along for the ride. After recognizing the voice, AJ began a second series of screams, accompanied this time by pounding on the walls, but like the first time, it didn’t help, and so she was forced to just float in the liquid, waiting.
After what felt like an hour, something started to happen. Not a good something though, as she felt her prison move, the liquid sloshing around, and this time getting into her mouth, something she’d kept from happening the whole time she’d been swimming in it. That little bit in her mouth told her something important though. It told her where she was. Before she could make any use of that, however, there was suddenly a whirlpool forming around the pole in the center of the fizzy lake, and it quickly dragged AJ beneath the surface again, the earth pony crying out only once, her scream coming out as a bubble.
The suction carried AJ downward, slamming her into the pole…straw, several times, before finally she got to the bottom, and was pulled towards the opening at the bottom. Not going down without a fight, the earth pony spread her body out blocking the straw’s lower end with her form, as she tried to resist the pull of whoever was sucking on the other end. Of course, seeing as how she was small enough to fit up said straw, it was no contest, and after a few seconds of holding out, Applejack folded, literally, and shot up the straw.
She was rocketed upward, and then tossed out of the top of the straw, and into some pony’s mouth. Before she could do anything about this though, she felt even more suction, and while she tried to grab onto the tongue with her hooves, it was useless, the saliva providing no traction for her, and so she was pulled back, and with one motion, swallowed down with the rest of the drink. The trip down was shorter than she thought it should be, as she moved down the tube of soft flesh, and was finally tossed out into a wide open space filled with even more liquid, this one bubbling as well.
She panicked as she flew over the churning stomach acids, expected to hit them and then meet a painful end. AJ was therefore surprised when, after splashing down, she was bubbled back to the surface, not tingling as she was being broken down into food by whatever pony had swallowed her, instead, gently floating on the top of her stomach juices. Actually, the bubbling and slight warmth made the experience rather pleasant, and when she was sure she wasn’t being digested, Applejack decided to enjoy it, since this was much better than how most of Rainbow Dash schemes ended for her. Mind, thinking about how she was getting out made her realize she was going to need one mighty shower.
***********************
Rainbow Dash started struggling against whatever she was in, trying to move against the soft thing below her, and the heavy thing above her, but it proved to be useless. She was strong, powerful, and the best athlete in Ponyville, as she’d proved to Applejack time and again. However, despite all those achievements, right now she was just a little pony fly, and that meant it didn’t take much to trap her somewhere. Not really seeing the point of pointless struggles, and finding the thing beneath her to be very soft indeed, is it any wonder she eventually closed her eyes, and started napping.
Mind, she woke up from her nap fully aware of what had happened, as she came at the problem with renewed energy and speed, her wing flapping hard, as her legs pushed against the stuff above and below. Luckily for Rainbow, the weight above seemed to have greatly lessened, feeling at least 20%, probably more like 80% lighter. This allowed her to wiggle and worm her way forward, to escape whatever was trapping her, and soon she saw the light of day outside, her eyes going wide with excitement as she drew closer.
Just before she could completely escape though, a new pressure, this time a thousand times worse, seemed to come from both sides of her, and she acked as she was once more pinned by the weight. However, thanks to the light from outside, she could see that the stuff below her was holed, and had a rough looking brown edge, while the stuff above her was ridged, like a leaf of some kind, an image reinforced by the green color.
Rainbow was still trying to puzzle just what she was seeing, having failed to notice that she wasn’t breathing, and thus wasn’t smelling the stuff around her which would have clued her in. She did figure it out on her own though, as she was still staring towards freedom, when freedom suddenly turned rather unpleasant. In specific, the view outside shifted from the park on a sunny day, to staring directly into Twilight’s mouth. Her teeth glimmering in the sun as saliva dripped from the top of her mouth to the bottom, and her tongue quivering a little, as she moved the sandwich, which Rainbow was in and was obviously held in her hooves as there was no magic glow.
Dash tried to cry out, of course, but by the time she did, she was already moving towards Twilight’s mouth, and so had no ability to stop herself, as she was shoved inside. Even if she could have shimmied backwards, she wouldn’t have made it far enough fast enough to escape, and so she was contained in Twilight’s maw, as the lower jaw dropped, the pressure above being released, and Dash instantly shooting out of her prison and into free air.
Well, free-ish air anyway, as the maw around her remained closed, Twilight chewing the mouthful with her lips closed, her flat molars coming together like something from a school movie, and nearly causing Rainbow to gag as she watched the formally solid sandwich get crushed and mulched, while saliva mixed in with it. Speaking of saliva, Dash wasn’t paying close enough attention to it in her state, and so when a huge drop fell from the roof of Twilight’s mouth, Dash found herself all wet, and thus, not very good at flying, slamming into the mare’s tongue with a splat.
Before Dash could really process that, she was pushed by the slimy member in between Twilight’s teeth, landing roughly on the bottom set, and staring right at the top set, as it hung above her, and then rushed to meet her, the two sets of molars coming together with a clack. That sound made Rainbow Dash, who’d closed her eyes at the last second, open them to find she was not smushed by Twi’s chewing, and instead was just lying there on her teeth, which met again, and then again, Twilight not enjoying having a meal that resisted her.
Unluckily for Rainbow Dash, Twilight took that as a challenge, and with a toss of her head, everything in her mouth began to slide towards the abyss of her throat. Rainbow tried to fight that powerful suction, but after a few moments of trying to get power from wet wings, and grabbing onto everything, Dash tumbled off the back of Twilight’s tongue, and then descended with a gulp, plummeting down her throat.
The arrival in the stomach was met with Dash flapping her wings to stay out of the pool of juices, hoping AJ had avoided a similar fate, and then slamming face first into one of the walls. After doing that once, Dash, seeing a way out, did it again, and again, trying to hit it harder each time. However, rather than getting Twilight to notice her, it only caused her to take a drink, and so Dash was soon washed into the liquid, noticing only vaguely that she wasn’t turning into rainbow goo, while she fought and kicked, going to do so that whole way as she was passed down, until the exit at the end.
