Contains: Unexpected Pregnancy, bad onomatopoeia, morning sickness, implied oviposition and it's consequences, clogged sinks, worshipping the porcelain throne. And of course ~~vomiting duh why are you reading this story if you don't like vomit~~.

Surprise Sickness - 1

"Hhhnnclkh!"

Jolting awake with a gag was a bad start to the morning. Skittish shot up in bed and covered their mouth in reflex. The creeping feeling of something traveling up their throat went away after a tense moment though...to be replaced with an intense dizziness from moving so fast. The short haired unicorn groaned and slammed their head back into the pillow, using their TK to smush it against their ears. Their distended stomach started to burble and let out an unhappy growl as an icy sting started to spread throughout their stomach

They may have been able to pass it off normally as indigestion. If it weren't for the very noticeable round bumps they could see in their distended stomach. The small mint size eggs they were force fed before had suddenly begun to balloon into golf ball sized eggs. Slowly and carefully, they started to slide out from under the covers, careful to not add any more disturbance to their increasingly slush filled stomach as it seemed to get louder and louder. One hoof touched the ground, and just as they were about to position themselves more carefully for touchdown the side of the mattress pressed hard against their swollen stomach.

"Oh no..." was all they could muster as they could feel something POP inside their stomach. One of the eggs ended up bursting open and filling their tortured stomach with glowing green yoke. Now they scrambled out of bed, trembling and panicking as tingling nausea flooded through them. Drool pooled into their mouth quickly, leaking out as they rushed towards the bathroom through their hallway.

"Uuarp!...fffmmm..hooaarp!"

They could even manage a curse as their spasming stomach forced more burps and dry heaves up their throat. Why did they leave the bathroom door closed!? Trembling, they could barely force the door open with their hooves as their last resistance to their churning stomach faded away. Vomit was surging up their throat just as the door swung open. With the toilet far away, Skittish was left with no choice but to swing over to the sink blindly as they hurled into it.

"Brruuaaaak! Ooagh, please..."

It was just a short spew, a little splashing of green goop that splattered over the faucet(missing the drain completely). As each short breath turned into increasingly louder burps though, they knew it was just the first of many bouts of regurgitation their festering stomach has lined up. Another burp transformed into a heave as more slimy yoke sprayed out of their mouth, ejected out with a surprising force from their egg-filled stomach.

With the extra time to aim, they managed to force it to land into the actual sink this time, making a small whimpering hum as the hurl lasted even longer, with some of the liquid forcing its way out the unicorn’s nose. Skittish felt more than liquid this time, it was mixed with bumpy black jelly in a revolting puree. Soul Lantra described the taste as ‘Gasoline Boba Tea’, but he still didn’t expect the horrid acidic artificial sweetener aftertaste. Dwelling on the taste for more than a few seconds made them want to throw up just from pure disgust alone.

Before Skittish could even catch a breath, their throat bulged again with another pint of yoke. Caught off guard, they almost choked and gurgled on the foul ovum as a chunkier mixture of it burbled out like a waterfall. Their vision swam along with their creaking tummy. They braced their forehooves against the sink and swayed side to side like they were on a rickety cruise ship. They couldn’t even keep themselves still as they blew chunks again, barely able to aim towards the drain and instead painting their counter green. In their blurry vision they could see that even with their misses the sink was filled up halfway. Their thick green and black slurry refused to go down the drain.

The incubating unicorn didn't have time to lament their mess, a flurry of micro-burps and breathless gags signaled the coming of a final bout of sickness. They took a deep breath through their boiling bile blasted nose and steadied themselves, bracing their hooves against the wall. A small belch broke the flood gates as their gullet was hit with the pressurized blast of the abortive smoothie, each tiny gurk leading to another pint of puke splatting into the overflowing sink.

“HHRRRAAAALH-HOOUARF!”

It was only a few seconds, they burp-chucked almost 6 times in a row with no relief in between. It felt like minutes. Each spray of upchuck was a full body event. A single rumble from their stomach reverberated through their body, before they could feel every single tremor from their rapid regurgitation’s passage up their maw. When all was said and done the sink was filled to the brim, nearly overflowing with a layer of frothy chyme.

With a great sigh of relief they wiped the sticky yoke dripping from their muzzle and pulled away from the bird bath of hurl they just made. It was almost impressive in a very miserable way. Somehow all that was in their stomach, and at least they managed to get it all out pretty quickly...

GWwhwoRgh

“Ugh, not again, please! How much more could there be...”

A wet acidic burp that stung their sore throat was his answer. With a resigned sigh, Skittish put their mane up into a ponytail and waddled over to the porcelain throne that was waiting for their worship.

"Hmm? You vomited all morning? And it was the eggy puke right?"

Even trying to think back to it made their throat tingle from trauma. After they filled a sinkful of puke they still had to move to the toilet to finish. It was less intense vomit, just mostly a clearer yellowish green liquid that time. But they were stuck there for almost an hour. Although a good 20 minutes of that time probably was spent just belching as they still didn’t feel safe enough to move away. That turned out to be the right call because they had another bout right after.

“Yes...Please tell me you got something ready to just get these eggs out of me please!”

Soul Lantra laughed nervously, a very bad sign.

“Yeeeaaaah. So, uh I know what you got attacked by: The Emerald Gastric Water Tentacle. Must’ve snuck up on you while you were passed out by the river, and uh ‘implanted’ in you somehow without waking up. Very sneaky creatures. They have a minor paralysis poison that probably helped out...”

Skittish groaned, in frustration for once. She was totally trying to not answer it outright, instead going on a tangent about how cool their tentacle rapist is! They knew of a pretty sure fire way to get her to blab at least.

“So they’re uh, unabortable then? Or at least you don’t know how to do it?”

“Wh-Wha-Of course I KNOW how to do it! Who do you take me for, some Bit Store Alchemist!? It’d just be illegal that’s why! They’re an endangered species and some treehuggers got together and petitioned to make them a protected species! Damn hippies!”

The green unicorn smiled slightly, questioning her ability always got her flustered. But the answer was still upsetting enough to make that minor satisfaction go away.

“Okay okay, I believe you. But uh, where does that leave me? Am I going to just have to...wait till they come out?”

“Yup! Sorry, nothing I can do unless I want to torpedo my career! Can’t give you an antiemetic since the puking is very important to the entire incubation process. Don’t worry, you’re gonna be a fantastic mom. I’ll even move in with you to help you carry them to term!”

Skittish shivered from the faux-motherhood talk. At least they thought that was it, but then the icy sting in the pit of their bloated stomach began to become unignorably ominous.

“Mmmhf, how long is it gonna last? B-Be quick, I think I may have to hang up here soon.”

“3 months! Not as long as a normal pregnancy luckily! But you’re gonna have this uh ‘Morning Sickness’ the entire time probably. First it’s just gonna be the bad eggs bursting, but later you’ll be hurling up new and more interesting slimes. Honestly, I think I’m gonna come over and study you for this entire pregnancy! Help out too, there’s very few documented cases of successful incubations so I gotta make sure it goes well! That's fine with you Skit?”

The mare only heard silence for a moment. At first she thought they were just deep in thought, contemplating their answer. That’s okay though, she can wait! And it'd be very rude to just invite herself over without Skittish's permissio-
“HHHHUAUUUARRGHL!”

Their loud retching was still perfectly audible even with the bathroom door slammed shut, and the phone 2 rooms away. Soul decided that was reason enough to invite herself after all.

“Ooh, uh. Okay I’ll be there soon! Just uh, hang in there!”

The Unicorn pulled away from the toilet bowl panting and coughing just as Soul hanged up. They at least managed to get to the toilet first before losing their breakfast. It was probably a bad idea to try to eat so soon anyway, but for some reason the unicorn felt absolutely starving and couldn’t resist. Looking down at the result of their latest emesis, they noticed it didn’t look like the previous hurl. It was real food at least, half digested oatmeal, but it was given a slightly green tinge as their bile seemed to still have that dark green color to it. Their bile also was bubbling, like it was a freshly poured soda.

“Huh...Whatever.”

Skittish shook their head and paid the anomaly no mind as they flushed the toilet again. That seemed to be the last of it for now at least. They looked down at their stomach for a few seconds, daring it to churn and roil again, but for now it was at peace. Feeling confident, the unicorn trotted back into the kitchen to brush their teeth and get the weirdly sweet flavor out of their mouth. The bathroom sink was still clogged even after their best attempts to clean it (they would just end up clogging it again if they stuck around it any longer). Skittish let out a frustrated grunt after spitting out their toothpaste and flopped onto the couch again, pressing a pillow against their head.

This was going to be a very very long 3 months...
