(Underfell sans x reader (female)) UNDERCOVER

Trivia

         Its been a week since you and Sans went on a date together and since then, you can't help but feel flustered and nervous every time you're around him. You also noticed that he has been trying to find excuses to be with you like walking with you while you're on patrol with Papyrus as he scouts ahead for humans. He also would hangout with you at your sentry station too since there was no one to keep you company.   

        It happen to be one of those days when you were at your post with Sans as you the two of you were just chilling figuratively and literally. There was a strong gust of wind along with a bit of snow making your clothes become useless as the wind was becoming colder.

You noticed that Sans was getting cold too and he zipped up his jacket.

"are you sure you still wanna stay out here? a storm is coming in." Sans says.

"One of the rules of being at a sentry post is that we're not allowed to leave it even when there's a blizzard on it's way." I say.

         A strong sudden gust of wind sweeps you off your feet causing you to fall, you've never fallen by wind this strong before. You crawl under your sentry station to avoid anymore cold winds. Sans watched you do this and crouches down to see what's going on with you.

"what are you doing?" He asks.

"It's w-warm-mer d-down here." I say shivering.

"really now? you don't seem very convincing to me." He says amused.

"W-well it's n-not w-warm but th-the c-cold is more t-tolerable." I say chattering.

        Sans crawls in with you making the small space very crowded. You repositioned yourself  with your back against Sans'chest, he unzips his jacket and wraps it around you without taking it off of himself. You were too cold to care about how awkward the situation you were in as you were slowly warming up from Sans. 

"How do you produce body heat? you're just a skeleton." I ask Sans.

"magic." He response.

        You knew you were going to be here for a while so you decided to ask Sans your burning questions about how he does the things he does since he's a skeleton.

"How the hell do you and Papyrus eat?"

"magic." he says again.

"But you have no organs, so why do you feel so squishy?"

"magic."

"You have no lips, so how do you speak?"

"magic."

"So you have no lips, so how do you have a tongue?"

"i'm pretty sure you know what the answer is going to be." Sans says amused by your questions.

"...Magic?" I say.

"and we have a winner!" Sans says jokingly.

You fidget around a bit feeling embarrassed by Sans.

"somthin tells me that you still have a few more questions."

         You do have more but they are a bit more 'personal.' You did want to know but you felt too uneasy asking him them.

"I do but they're too awkward to ask you." I say.

"awkward you say? i'm sure they can't be that bad." Sans says as he turns you around and basically straddling him.

"It's nothing, just forget it." I say annoyed.

"come on i know you have more." He teases.

"Just forget that I asked."
