Underswap Sans x Reader

Prologue

((ALRIGHTY..LETS GET DOWN TO WRITING *Cracks Knuckles* >:3))

It had been 2 months since you had fallen down into the underground and became friends with the skeleton bros. You found both of them to be quite friendly and nice but what caught your eye was a certain short skeleton who pretty much only wore blue so you gave him the nickname 'Blueberry' for two reasons.. 1. You thought it was cute (but not as cute as he is Cx) and 2. Because it seemed 'fitting'. You found Blueberry's attire of clothes to be very adorable on him. He wore a blue bandana on his neck, A grey T-shirt with what looked like some sort of armor on his shoulders, (sorry that i don't know what they are xP) along with some blue gloves that matched the same shade of blue that his bandana was and some boots that were yet again the same shade of blue with some grey shorts. (I can pick out what he wears whether chu like it or not! C:< because who's the author? That right! Me! X3 but..you can change it to whatever you want him to wear.)  So yeah..there you have it, an adorable blueberry..oh wait i didn't explain his personality and his real name. His real name is Sans but he likes to call himself 'The great Sans!' Which you find very childish and cute. Next..his personality, basically he's just like a kid. Childish,pretty much Happy-Go-Lucky all the time, Hyperactive, innocent meaning he doesn't understand what some things mean.. (Blueberry: "Hey! I know a lot of things!! Otherwise i wouldn't be calling my self the great Sans!!" Author: *Giggles*) and lastly, he's always positive and funny at times.

You had become very close friends with the skeleton brothers over time and you tended to visit them very often since you never really had anything else to do. Everytime you arrived at their house Papyrus, Sans brother, always had a few more puns to share with you to make you laugh while Sans was always full of excitement for to you try his cooking since he knew you enjoyed it but lately you've been noticing that he hasn't been acting that way lately and has been keeping a distance away from you making it almost rare for you to see him ever and when you did get a chance to even talk to him, he would always have this light shade of blue go across his cheekbones which you presumed was blush. So you have been trying to get him to come out more often and to stop locking himself in his room because you missed your old blueberry. ( ;) )
