(OLD VERSION) One Big Unplanned Mistake (Sanscest)

Chapter 2: Of course there's no butts, skeletons don't even have an ass

A week has passed since Sans had found out he was pregnant and a lot of things had change on his health,  he had also started wearing a lot of layers of clothing to conceal the glow his stomach is making cause by his magic.

This passed week Sans found himself losing a lot of energy quickly, his bones would ache everytime he move for more than 5 minutes, everything he eat he would just throw up later, he couldn't even sleep properly without having nightmares.

And because of that Sans is currently in the kitchen seating beside the table as he ate a soggy taco from yesterday. He would do this every night when he was sure Blue and Red were asleep, he would go down the stairs to the kitchen and eat any leftovers for him to just throw up later.

Sans din't even know what to do anymore so he would just sometimes sob in his room when he was sure no one was around and he would stay close the bathroom to be ready so he wouldn't make a mess if he would throw up.

The kitchen lights then flickered turning on startling Sans slightly as he looked at the kitchen door seeing it opened Red on the side who had a worried expression for a split second before turning into a relax tired expression.

"For fucks sake Sans I thought you were a robber" Red said tiredly sighing as he walk up to the kitchen counter.

"S-sorry......" Sans said quietly but was heard by Red startling him slightly since he never heard Sans say sorry to him without being pushed by Blue or Papyrus to do so but he decided to ignore it.

"Want some coffee?" Red said already making two cups of coffee knowing full well Sans would say yes.

Sans then remembered something he found on the internet that when your pregnant caffeine is not allowed he clench the taco in his hand is he even going to keep the baby?

"No" Sans said not looking at Red at all "Wha-what?" Red said. 

"I don't want some coffee...." Sans said looking down at his taco, he doesn't even know if he would keep the baby....... Or even have it survive since he doesn't even know if his magic can even nourish the two souls completely.

"Sans are you sure your fucking ok?" Red said putting his hand on Sans forehead.

Sans felt the souls tingle in his stomach feeling their other parent near as Sans shrug the feeling. He quickly slapped Red's hand from his forehead giving Red a stern look "Im fine Red its just a stomach bug" 'No it's not a stomach bug Im just fucking pregnant' Sans thought to himself.

"Why are you guys in the kitchen this late at night?" Blue said coming in seeing his boyfriend and best friend.

"Nothing really I was ju_" Sans said but stop feeling his stomach clench, he quickly run as fast as he can to the bathroom as he put his head in the toilet throwing up.

Both Red and Blue watch Sans worriedly as he throw up in the toilet. Sans then gathered enough strength to reach and flush the toilet.

"Ok that's it Sans you have been sick for a week now and you aren't showing any signs of recovering so I'm gonna send you to your brother and Stretch's house for a week so you can get a check up from Alphys since she lives right next to them" Blue said.

"Bu_" Sans was about to protest but Blue cut him off "No buts" Blue said sternly.

"Of course there's no butts, skeletons don't even have an ass" Red said snickering.

"Skeletons may not have an ass yet I still found you a shitty asshole" Sans retort back.

"LANGUAGE"

Sans sighed knocking on the front door of his brother and Stretch's house. He doesn't really want to bother the two but his pretty sure Blue had already told Papyrus about his 'illness' and got his brother to worry over him.

The door flew open in it showed a worried looking Papyrus yup Sans was right his brother got worried about him "BROTHER, BLUE TOLD ME ABOUT YOUR ILLNESS ARE YOU DOING ALRIGHT?" Papyrus yelled.

"Geez Paps I'm fine I'll probably just need to rest and ask Alphys for some medicine" Sans said grinning at his brother, man how he hate lying to him.

"Are you sure brother?" Papyrus said still concerned for his brother "Yeah...I'm sure" Sans said trying to cover his uneasiness.

Sans grumbled as he was being drag to the basement by Alphys since she had a built in lab there. Alphys gestured Sans to seat on a chair. 

Alphys check Sans stats and when she did she gasp "S-sans y-you're magic it h-had tr-tremendously drop wh-what have you b-been do-doing lately?"

Sans shrug he doesn't even know what to say to her "Ah.... you know sleep"

Alphys sighed "Y-you know w-whats g-going on d-don't you?" Sans just nodded in shame.

"Take of your shirt"

"Wow Alphys that was so straightforward what do you think Undyne would say if yo-" Sans said but was cut off by Alphys "S-sans I am n-not pl-playing your g-games, t-take of your s-shirt so I can c-check on y-your soul" Alphys said sternly.

Sans sighed it looks like he wouldn't be able to get out of this though....... It might help if someone knows about his little problem, he sighed one more time before lifting up his shirt as he heard a gasp from Alphys.

"S-sans y-you're_" Alphys said in disbelief.

"Pregnant I know, I found out a week ago........." Sans said looking down at his stomach.

"I-i think I k-know w-why your magic d-drop, I think i-its because y-your m-magic can't nourish b-both s-souls and y-you need to h-have the o-other p-parents magic d-donated to y-you for the souls t-to fully n-nourish" Alphys said.

Sans grinned sweat dripping off the side of his head "Y-yeah about t-that..."

"Oh G-god, Sans d-does the o-other p-parent not know?" Alphys said as Sans look down fidgeting with his fingers "Y-yeah"

Alphys sighed "I-i wouldn't ask c-cause I r-respect your p-privacy but you s-should tell someone f-for now l-let me d-donate some o-of magic t-to you"

"What the Alphys no_" Sans was about to protest but was cut off by Alphys

"Sans l-let me h-help you after a-all I'm y-your friend" Alphys said as she put her hands close to Sans stomach as it glowed, the souls shifted in Sans womb trying to identify the new magic while Sans relaxed feeling the pain on his bones lessen.

Alphys stop when she was now on her limit as he look up at Sans tiredly "Thanks Alph" Sans said sighing in relief as Alphys stutters "W-what friends a-are for?"

"HEY ALPH SANS DO YOU GUYS WANT SOME....." Undyne trailed off looking at Sans and Alphys seeing the two souls on Sans stomach.
