(Underfell sans x reader (female)) UNDERCOVER

Curiosity

         You walk out of the echo flower place and noticed a sign that said'Waterfall' and now glad to know the name of your favorite place. You sort of forgot how cold Snowdin was as you left Waterfall, the temperature was quite pleasant there. You wanted to explore more of Waterfall but you needed to get back and break the bad news to Grillby.

                                                     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

         You were walking past Sans' and Papyrus' house and your house as well, you couldn't stop thinking about the moment where you and Sans were holding hands and looked at each other. You've never seen Sans look at you that way before but you're not quite sure if he has the same feelings for you. After all you are a guy, but that doesn't mean he can't like you back.

         You almost past your house until Papyrus comes out and yells out to you holding your weapon.

"ARIE! YOU LEFT YOUR SCYTHE OUT IN THE FOREST! YOU NEED TO COME INSIDE AND HELP ME COOK DINNER!" Papyrus shouts.

"But I need to tell Grillby that i'm qui―"

"SANS TOLD ME THAT HE WOULD BREAK THE NEWS TO HIM, NOW COME INSIDE!"

         You trudge over to the house knowing that Sans is going to be stuck in your mind for the rest of the night.

                                                        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

         i walk into Grillb's and sit in the corner of the bar with my skull in my hands. i sighed and tried to get the thought of Arie out of my head. i can't be gay can i? Grillbs see's me and walks over to sit by me.

"Hey Sans, haven't seen you around for quite a while. By the way, have you seen Arie around lately? I gave him a five day vacation and they usually come back by the second day around."

         i sighed and remembered that i told Papyrus that i would have to tell Grillbs the news about Arie so he didn't half to walk a long distance.

"about that Grillbs, Arie got a better job offer from my brother and is now living with us."

i could see Grillbs smile droop feeling a bit hurt.

"Why didn't he come to tell me himself!?" he said annoyed.

"they were gonna tell you but i showed them around at Waterfall and that's about a two or three mile walk from here, so i went ahead and saved him the trouble."

"Well, he needs to come and visit once and a while, I actually started to miss him." Grillbs says sadly.

"it's funny how he does that..." 

"Does what?"

"you know, grow on ya. every time i'm around him, i just don't have the heart to get all tough and mean on him."

Grillbs smiled mischievously when he heard me say this.

"Oh I see, you have feelings for Arie~" Grillbs teases.

"it-it's not like that!" i say embarrassed.

"Come on Sans you gotta admit that Arie is not your average male monster. He's too short and petite which I find quite adorable as well you too." he teases more.

         he wasn't wrong, Arie was a bit short for a guy and not to mention petite. now that i think about it, when i held onto his side to make sure he didn't fall when i teleported to Waterfall, he was quite...'curvy'. could he....nah that's not possible.
