Flask loved her days off of work. Not because her job was bad, but because she enjoyed the time to relax, and unwind. She'd slept in until 10, made herself a wonderful breakfast, and she'd even done some cleaning. Flask was in her living room, and she smiled as she stepped back from her TV, which she'd just dusted off. She walked over to her couch, and with a happy sigh, the mare sprawled out on the soft, oversized piece of furnature. She let her body go limp on the couch, and right as she let out a happy, relaxed sigh, the doorbell rang.

Of course it did.

Flask's groan of annoyance lasted even longer than her sigh of satisfaction, and she got off of the couch to head for her door. Opening it, she caught little more than a pegasus mail truck lifting off into the sky, and of course a box on her doorstep. "Huh" The mare murmured to herself, as her magic picked it up and brought it inside with her. She set it down in front of the couch, locked her door back up, and sat down on the couch to open it. Flask had a habit of opening things without caring about whatever documentation or instructions came with them, so she did little more than scanning the shipping label for her name before opening it right up.

There wasn't much inside, really. The box had some really nice packaging inside, surrounding a strong plastic container. Hell, it looked better than some of the stuff Flask used in her kitchen! She lifted the container out of the box, then pushed it inside. Sure, there was a stack of papers in the bottom, probably instructions or something, but who needed instructions for... what was this, actually?

This had to be some sort of prank. It looked kind of like silly puddy, but it was the color of her latex work suit, and there was a lot of it. Flask thought of Beak... was this from him? Was it some sort of prank? The mare shrugged slightly, and her magic took the lid off. She brought the container close to her face, and she peered into the odd liquid, frowning down at it. It didn't smell suspicious, so she set it in her lap and poked a hoof into the stuff, feeling it squish around her hoof and make room for it.

Well, that turned out to be a bad idea, because her hoof displaced enough of the liquid for it to overflow the sides, and to make it worse, Flask dropped the container! Somehow, her magic couldn't actually grasp onto the Latex itself, and when it overflowed the box, it cut off her connection to it. The mare let out a groan of frustration, looking down at the mess... her hoof had sticky whatever-it-was stuck to it, and it had splashed all over the carpet, the couch, her lap, her hind legs... it was stuck to everything, and she was already borderline pissed off at what a mess it was going to be to clean!

The mare closed her eyes to take a deep, calming breath, but then she felt something move. She opened her eyes wide, and she let out a startled squeak as she caught the stuff in motion! It had begun to creep up her leg, and she shook it a little bit, even though she already knew that such a thing was worthless. The mare stood up, and as she did, the odd liquid came with her, gathering against her legs and her underside. "How did- what?" she asked, taking a few seconds to look at the floor and the couch. Somehow, the Latex had seperated itself entirely from the furniture and the carpet, which was great! Problem was, it was now stuck to her- and getting worse!

The mare pranced in place for a few moments as her heart began to race, because it was starting to sink in that she'd gotten herself into quite a messy situation. The Latex was just beginning to get to the top of her hind legs, and on her front end, it was already to her chest. As it began to descend down her other front leg, She uselessly pushed at the latex on her covered leg, and found that she couldn't get a grip on it. Somehow, even though it was stuck to her on one leg, her free one couldn't even grasp it? This stuff wasn't making any scientific sense, but of course, Flask hadn't thought to consider that it might be sentient.

She wouldn't be learning that little fun fact just yet, though. The goo had just finished coating her underside, and something that happened to enter Flask's mind was just how comfortable it was. It was smooth, cool, and it didn't squish down her fur like her work suit did. Whatever it was, it managed to soak into her fur, leaving her limbs totally smooth and black. Right as it began to cover her flanks, Flask realized what she must look like, and her face began to redden as she thought of all the fetish related Latex gear she had seen when she went shopping for her work suits... was this related to that, somehow?

Her heart was pounding even harder as the stuff covered up her backside, contouring perfectly to both her marehood and her plot, and she felt the former wink just slightly as an ice-cold spike of arousal suddenly speared her thoughts. "Oh, Surely this isn't..." The mare muttered quietly, as she started to walk towards the living room entryway, she felt the Latex tensing up, making it hard to move. This only made things worse, since the idea of being trapped by this stuff was starting to turn poor Flask on. But she was still scared- surely, this stuff meant harm? Well, she got her answer pretty quickly- as the Latex began to make its way up her neck, it also spread open the plump outer lips of her marehood, and it pushed inside of her, making her gasp sharply. Shudders ran up and down her body as she felt her clench down on the invading liquid, and she could swear she felt it squeezing her ass. If that wasn't enough, the Latex coating her soft teats had begun to squeeze them, and that only sent even more tingles of pleasure through the mare. For some reason, Flask had assumed that this stuff would be stopping at her neck, and she whimpered slightly as she felt it coming up over her chin. The mare opened her mouth for air, but all that did was allow the stuff to come into her maw!

Then, the panic came back a little bit. She felt the goo rushing down her throat, and she couldn't breathe! It covered her eyes up, turning everything dark, and she tried to take another breath before she heaved most of it back out- the goo had just found her g-spot, and it had pressed firmly against it, sending a rush of pleasure through her body that made her give quite a loud (though muffled) moan of pleasure. When she went to breathe again, she found herself sucking in a breath, and while it felt kind of odd, her attention was focused elsewhere as the Latex finally covered the tip of her horn, fully encasing her exterior. Now that it had done that, it went back to pleasuring her clenching tunnel, trying to milk more of her slippery arousal from her marehood. The suit needed it, as it was able to convert it into more Latex. And it was going to need a lot for its first impressions with its new owner! Flask found herself unable to move as the Latex kept her in place, sinking deep into her from every end. It began to push inside of her ass, it sunk under her eyelids, it delved into her ears... she was properly coated with the stuff inside and out, in such a way that her body would still function as normal. It could even thin itself enough to allow her to see the world properly! Or act as sunglasses, if she wished.

For now though, it was keeping her blind, and it plugged her ears, too. Cut off from sight, sound, and even smell, as it filled her nose, Flask could only focus on the _sensations_ this thing was giving her, and she was loving every second of it. The suit was hitting buttons she didn't even know she had, and the poor mare was letting out all sorts of adorable little gasps and moans. She was approaching an orgasm, and it seemed the suit could tell- the latex grasping her clit began to gently squeeze it, testing her sensitivity as it poked and prodded inside of both her marehood and her plot. It turned out that Flask was pretty damn sensitive, because squeezing her clit made her tense up and shudder pretty heavily. The suit used that to its advantage, and it began to massage her teats as it focused on squeezing her clit in just the right way to make her cum, and it wasn't hard to pull off. She cried out as she came crashing into a strong orgasm, shaking her legs as she began to gush. Flask being a 'squirter' was useful for the suit, because that gave it a lot more material to work with. Between the sweet marecum she was making and the various fluids found inside of her, the suit had gathered what seemed like plenty of Latex for what it wanted to do.

While Flask rode out her orgasm, the suit continued to massage the insides of her clenching pussy, though it was more gentle to keep from overloading her. When it ended, even though she was too scatterbrained to walk just yet, the suit began to make her move. It was plainly obvious to her that it was taking her up the stairs, but from there she couldn't tell where she was being led to. It didn't help that it was also softly rubbing her teats on the way, since it had somehow figured out that hers were rather sensitive. Still, she was lost in her own house, until the suit had her hop up onto her bed that is. How did it know where her bed was? How did it open the damned door? Why did her back feel heavy? She wasn't getting answers to the first few questions, but the third one, she got her answer for that. The weight on her back was lifted, and her front end was pushed down to the bed. The mounting position made her shudder- she was mostly into mares, but this seemed like a rather specific position- but this thing wasn't a stallion, was it? Well, no. It wasn't the weight of a pony that settled onto her. It was the clenching grasps of tentacles that took hold of her limbs, and she felt the latex around her mouth and her backside start to liquidize. She started to wonder why, and she got her answer in the form of three thick, dripping, slippery Latex tentacles.

The first one stuffed itself into her mouth, and from there, down her throat. It wriggled a little inside of her, but Flask couldn't help but desperately suck on it, happy to have something muffle her moans. Next came her ass, as a second, slightly smaller tentacle plunged inside, filling her up and making her clench tightly around it. The mare whined around the length filling her mouth, and she struggled against the vines holding her against the bed. She was surprised to find that the coating wasn't stiff anymore- she could move! Well, if it wasn't for the vines holding her to the bed. Somehow, she found that hotter... she was able to struggle, but she still couldn't escape. She wasn't struggling to get away, though, she was struggling out of frustration that the suit was doing nothing about the burning need she felt in her soaking wet marehood. With a wet squelch (that she couldn't hear), a third vine, thicker than the other two, plunged deep into her marehood, making her squeal as it filled her tunnel all the way to her cervix- which thankfully didn't hurt. Now that all three vines were in place, the suit really started to put things into motion.

And it began to thrust. Right as Flask was overcoming the shivers of estascy she had felt when the vine stuffed itself into her pussy, all three of them began to move. It became clear why the Latex around her entrances had liquified- the suit needed to allow its tentacles inside of her without interfering with the outer coating, and it was just a fun side effect that it made things rather messy and slippery, perfect for a hard fucking. Flask found herself rocking her hips in time with the tentacles as they pumped into her- the two behind her would stuff themselves inside of her, and as they pulled back out for another thrust, the one in front of her would stuff itself back down her throat. Flask found herself holding tight onto the bed as the suit pleasured her, and somehow, it still had more surprises up its metaphorical sleeves! Flask could feel two tentacles press against her soft teats, and they suctioned themselves onto her nipples, then, to her surprise, she felt them leaking Milk! The realization made Flask shudder against the vines, which were growing thick around her as she fed them more and more of her slippery arousal. And now they were milking her!

Somehow, the suit had set her body lactating, and with even more fluids at its disposal, it got even more bold. The thick vines plunging inside of her began to speed up a little, and the other vines wrapped around her body began to explore. They groped her flanks, they wrapped around her neck, one of them even wrapped around her horn to give it a curious squeeze. Sadly, Flask's horn wasn't as sensitive as some unicorns would be, but the suit didn't even need that to make her cum. Flask was getting close, too. She had begun to clench tightly around the vine ramming itself into her pussy, trying to hold it inside each time it pulled out. It was entirely useless of course, but it did make it feel a little better. She was also moaning a little louder, even if it was muffled again and again by the vine stuffing her throat. The one in her ass felt amazing too, and the way it was milking her teats, oh, it all felt just wonderful. When it became obvious that Flask wasn't going to hold on much longer, the Suit seemed to get sloppy with its movements, as if it was also approaching a climax of some sort. The tentacles had begun to lose their tempo, stuffing themselves into Flask recklessly as they began to shake the bed with their force and weight.

Flask began to shudder as an orgasm began to rise up inside of her, and the suit took action. Throughout her rough fucking, it had been gently massaging her clit, but now the suit wanted her to cum, and it began to firmly rub it, both on its own and with the big vine as it rammed into her pussy. This was almost too much for Flask, and when she came, she let out a shaky, ecstatic squeal of pleasure, and she clenched down hard onto all three of the vines, just barely managing not to bite the one inside of her mouth. As she entered her orgasm, the mare limply thrashed on her bed, holding tight onto the covers as she began to ride out the rollercoaster of sensations. And to her delight and surprise, she felt all three vines suddenly ram themselves deep inside of her, and begin to flood her with more Latex. It was something she had never experienced before, because instead of pumping the stuff inside of her, the vines would liquidize some of themselves, pull back, then thrust even deeper to shove the liquid section deeper inside. Then, they would start over again, starting a cycle of thrusting themselves deeper and deeper into her with seemingly no end, stuffing her womb and her belly full of cum at the same time. The vines holding onto her began to slink away as they joined the wriggling lengths that were pumping themselves inside of her, and before long she began to look somewhat pregnant with all the Latex filling her up. Throughout this process, poor Flask managed to endure multiple orgasms, shuddering and writhing on the bed helplessly as the suit pumped itself inside of her.

Eventually, it came to an end. The last few inches of tentacles stuffed themselves into Flask, melted away, and joined the rest of the suit, leaving her sprawled out on the bed, panting and helpless to do anything other than lay there and attempt to piece together something that resembled a conscious thought. The suit thankfully had stopped milking her, leaving her body unmolested so she could lay satisfied in the afterglow of the most intense orgasm she'd ever felt. The cold glass of a cup gently touched against her lips, and she drank some water obediantly, not even questioning where it had come from. The suit had brought it up on the way, assuming she would need it. She was gently pushed onto her side, and her soft blankets were pulled up over her, making her put on a happy, adorable smile as she relaxed on her soft bed. Something odd about the situation is that despite experiencing the kinkiest, messiest sex of her life... both Flask and her bed were spotless! Whatever this thing was, she loved it. And as she let her warm, comfortable afterglow slowly drift into the quiet, silent abyss of sleep, the suit swiched off the lights in her room, finally unblocking her ears, eyes, and nose.

-------=======[A bit Later]=======-------

As Flask slept, Kink allowed all of the extra Latex inside of her to seep back out, piling up behind her. Kink had managed to milk enough cum and, well, milk out of Flask that she was able to form her body together on the bed, and as the worn-out scientist slept, Kink snuggled up behind her, hugging the mare close to her with a big, happy smile on her face.

Tomorrow was going to be a bit strange, for sure.
