Gaster x reader

What the fuck Gaster?

"Gaster.... Don't"

"But (Y/N)--"

"No Gaster"

"(Y/N) you really have no say in this"

"Sans shut the fuck up and help me!"

SPLASH

"Damn it Gaster!! I said not to!!"

                                                         Now I know what you might be thinking, 'What the hell is going on?'. Yeah I know, but there is a reasonable explanation for what's going on, I promise. You see Sans was invited to go to a X-Mas party for all the other AU's, buuuut... He brought Gaster along and literally dragged me as well. So here's what happened.

One hour earlier

"Please (Y/N)?"

"Gaster for the last time, Stop being a fucking perv and trying to get grandchildren from Fell and Science Sans!"

"Fiiine!"

                                                  It has already been a few hours since we got here and Gaster is already trying to get the two AU's to fuck.... No wonder I didn't want to come, I knew I was going to be the damn babysitter for this fool.

Sigh

"Hey (Y/N) whats up? You okay?"

                                                  Looking over I noticed who was speaking to me. It was AT Sans. He looked like he was worried. Guess he has a right to, I am babysitting a grown ass Fucking monster!!

"Yeah I'm good. Just want to sleep."

"Oh! Well if that's the case then go lie down on the couch."

"I would but---!"

"(Y/N)!!"

                                                       Quickly turning around I was tackled by the ball of sunshine himself. Swap Sans. And right behind was Swap Papyrus. We both fell to the ground with him above me laughing our asses off with S.P. chuckling in amusement. 

"(Y/N)!!~"

"Hehe~ Hi Sans, Whats up you little cutie~"

"It's been a while so I got excited, Sorry..." 

                                                           Seeing him pout slightly I gently pushed him so I could sit up. I then gave him a giant hug getting a squeak from him.

"It's fine blueberry! I love your hugs!!"

                                                           Literally seeing his eyes turn into stars when I pulled away I got another hug before he jumped off and ran off to Fresh. I wonder what they are doing together. Hearing a chuckle I turned around to see a skeleton hand in front of me, looking up I realized it was S.P. Giggling I took his hand as he helped me back up.

"Been a while sweetie, how you doing? Haven't been falling much right?"

Rolls eyes

"Haha Real funny S.P. I've been fine. Well minus those numb nuts." I say while pointing over at my two idiots.

                                                               Raising a brow he nods. He then leaves leaving me with AT once again. Looking over at him I notice he's having a conversation with Reaper Sans making me smile and walk away. It would seem that the only one here who doesn't really belong is.... Me.... Frowning slightly I walk away from the others and sit outside. Looking up I look up at the stars this night. Their all so beautiful, they remind me of my sisters, Rose and Alyssa.... Looking down once more I hear A voice calling my name, looking over I see Gaster with a smile, but in his eyes lays worry. I wonder why.... Walking over and sitting he begins to speak.
