Locked and Loaded (Commission for krauser018)

“Package secured, moving to extraction… where is extraction again?”

The loud grunt coming from the other side of the radio line was all that was needed for Toriel to start blushing wildly, right before having to fight back the urge to issue a torrent of apologies for having forgotten to properly memorize the floor plan for the millionth time. She was lucky the spider was as helpful as she was; wouldn’t be the first time the boss monster got lost because Muffet wasn’t around to help guide her through.

“There should be a vent a few steps over to your left. Open it and go through, there should be an intersection after a few yards; let me know when you get there!”

She nodded, even though her partner couldn’t see it, and waddled over to where her escape route was. Her body had been a bit of a bother lately when it came to her assignments, seeing as it had decided to start growing in all of the right (wrong?) places of its own accord. While usually she was still nimble enough to get through tight spaces, finding a way into the compound an hour before had taken substantially longer than normal, and the moment Toriel spotted the vent she was supposed to go into, her heart sunk on seeing how tiny it was.

She felt like radioing in Muffet again, to ask for an alternate route. But with the facility already on high alert, that package she had strapped to her back needed to get out of there as quickly as possible. Sighing, Toriel yanked out the vent cover and carefully lowered the heavy-set briefcase into it, right before giving her body a bit of a squeeze everywhere. It was hard to tell which part of her was most likely to get stuck: her chest-covering breasts, her motherly, child-bearing hips or that beanbag she called an ass. It was a toss-up, really, and not one she was eager to flip a coin on, much less try in practice… but the alarms were still ringing and that package wasn’t going anywhere on its own, so down she went.

…

As expected. Even gravity wasn’t enough to prevent her bottom half from getting stuck in the vent, soft flesh overflowing even when covered by a skintight bodysuit, giving her enough pudge to hold onto while desperately trying to free herself from the stupid trap she’d thrown herself in. Miraculously, it seemed to work; through wriggling and squirming, her rear began to slip on through the tight opening, giving her just enough room to sink a few inches more… right before her bosom became stuck.

“Come now…” she mumbled to herself, wanting to issue a few choice words at her own body for betraying her like that. Her one consolation was that her feet were touching the vent, though that was hardly much of a relief considering her body was now irrevocably stuck at the entrance. No matter how hard she pushed, her tits refused to squeeze into the hole, probably not helped by the utter lack of space underneath for them to squish into, leaving Toriel firmly in place with no chance of recovery.

And what was worse, the radio had fallen too far away from her to be used, leaving the boss monster alone and without any prospect of rescue. Just like that one time three months before. She sighed, having no one to blame but herself; they had been the ones to indulge in their occasional growth spurts, deliberately keeping them going for long enough that their effects on her body compounded to the point they did. No one else had done that for her; it was entirely her doing. Still, why did it always have to come down to vents? Surely at some point their team would’ve thought to invest in some kind of high-strength wire and grappling hook combo, because frankly, it was getting ridiculous how often they had to cut metal off of her body. Plus the whole “wideload” jokes were getting old.

She hiccuped. A moment of panic coursed through her before her mind settled. Maybe it was just a hiccup that time; wouldn’t be anything new, it happened on occasion. Heck, she hadn’t even grown the tiniest bit, so she was probably safe! And yet another hiccup, again from nowhere and without any warning, leaving her feeling bloated and mildly uncomfortable. A pressure was building inside of her stomach, one that each successive yelp and flinch only increased, a force that grew in intensity with each noise escaping from her throat.

She knew what was coming, and it wasn’t going to be pretty; that her tits were feeling even tighter than normal after the tenth hiccup or so only served to confirm what she was already aware of, and the moment her belt loudly snapped off was the one she let out her last sigh for the night. There’d be no point fighting it anymore; not now.

The vent around her began to groan, the metal being bent out of shape as every hiccup brought with it more size. Seemingly out of nowhere, Toriel’s body grew in every direction, filling with what was either phantom, weightless mass or pure air, taking in as much as it could from the surroundings and already straining her trap’s ability to contain her. There wouldn’t be any ring of debris around her by the time the mission was over; hell, her team was lucky if there was a building left by the time she was done.

Of course, the boss monster was in no way worried about any of that; as soon as she felt herself inflate, any thought but that of indulging in her growth vacated the premises as quickly as she herself was supposed to have had, leaving only desire, lust and a little bit of her humor behind just in case anyone needed a bad pun about snails. Mostly lust though, to be perfectly honest.

The vent itself lasted a good minute or so before being busted beyond repair, unable to deal with the sudden expansion of flesh tearing it to shreds from the inside. For Toriel, this registered as a very faint, almost imperceptible sense of tightness around her waist that barely compared to what she was feeling overall; when one’s body rapidly became so expansive that it cracked through concrete, it was hard to care about a piece of easily-bent metal. Somewhere out in the distance, Muffet and the rest of the observation team were already facepalming at what was going on, correctly deducing that their infiltrator was going through yet another inflationary episode after they failed to report back. Well, that, and the odd moaning floating through the air to where they were.

The guards alerted by the many alarms congregated on Toriel’s location, hoping to find a single, regular-sized person they could surround a demand a surrender from. Instead, not only did they spot their quarry atop a roof, but had the pleasure of being given a front row seat to what was a doubled-up-in-size boss monster struggling to make room for herself amidst a collapsing building. Her chest had (literally) ballooned to nearly thrice its size, burying her face underneath it, while her ass and thighs widened enough to completely destroy the vent system she was supposed to have escaped in, leaving the package to fall down into the lower floors. Rather than worry about that, however, the motherly gote had to deal with a belly that seemed to be gaining size from absolutely nothing, yet another symptom of her sudden bouts of expansion.

For some, it would look to be heavy; it was certainly massive, after all, so clearly it had to be hard to carry around. The secret was that it was anything but; her inflated self was quite light, in fact, courtesy of it being some odd kind of wind magic going completely haywire, making it the primary reason why they struggled so hard to leave the tight confines of the structure they were stuck in: if she didn’t, there was a non-zero chance the pressure  of “poppping” out of her tight confines would send her flying out of control instead of just making her flail about helplessly just a few feet off the ground. Mercifully, she managed to dislodge herself just in the nick of time, a few brief seconds before her arms began to bulge out as well, leaving her arms stuck between countless folds of inflated flesh.

Down below, the multitude of armed personnel were aghast at the sight, with no clue as to what to do. Expecting a simple thief, to be given a living balloon that kept on inflating despite the lack of any obvious source of air was… confusing. Arousing to some, but mostly confusing. After a brief radio call with their chief of security, during which most of the group had to yell and convince them that they were, in fact, seeing what they were seeing, the guards vanished, only to return a few minutes later carrying several long ropes.

Toriel sighed, in the process inviting enough air into her that her cheeks began to puff up as well. She berated herself for even opening her mouth at all; it always ended up in the exact same thing, with most of her face buried by two colossal, puffy spheres attached to either side of it. It’d be bearable if it didn’t feel so good as well; her whole body was so wonderfully warm, despite being out in the cold night, that she might as well be taking a bath in freshly-drawn water. Her mind kept trying to relax, to succumb to the sensations and let itself move around aimlessly, adrift in a sea of its own making; it took Toriel trying to focus to keep her mind at least the tiniest bit sharp, even if it did nothing but let her watch as her imprisonment came ever closer.

The guards underneath her surrounded the building she was hovering around, firing the ropes from one side to the other with large grappling guns. A few of the hooks grazed her, almost ripping her suit apart in multiple places; it was a wonder how it was still in one piece, but that was hardly the weirdest part about that night. After a few minutes there were so many ropes over her body that most of her back was squishing between them, giving the men below enough leverage to start pulling her back down.

Perhaps they expected her to destroy the building, or at least flatten it enough to give them easy access. But seeing as how Toriel was light enough to float, all her body ended up doing was… press softly against the concrete. The destroyed vent was only made that way thanks to the silliness of trying to contain her; as soon as she was free, Toriel was no more capable of wrecking anything than a literal blimp was. A blimp that was now detained and in severe need of rescue, even as her body continued to slowly inflate, leaving her legs and now-buried feet for last. The boss monster would’ve loved to say something about that, but seeing as how her head was buried by its own cheeks, it became hard to do anything but moan quietly, silently complaining about her own predicament.

Off in the distance, Muffet threw her binoculars onto the ground and groaned loud enough for the rest of the crew to tell her to be quiet. She couldn’t believe Toriel went and got herself captured, again; she darn well told her to make sure to keep her magic balanced before infiltrating the compound, and now look at what happened! They were going to have to risk life and limb to get her back, and even then only when she deflated back to normal!

And who knows what she was going to look like after emptying out? They’d be lucky if they could even walk with how big they were going to get!
