(New Year's Special) AU Sanses x Reader

(No point to the song above. I just think it is very funny since I can't take him seriously. Also outfit is F/C long sleeved crop top, black tank top, black jeggings, and F/C tennis shoes).

(Y/N)'s POV
"Bye (Y/N). You'll love the surprise." Frisk winks and waves goodbye as he leaves with Toriel. They dropped me off at Sans and Papyrus' house for a surprise. I turn around to face the door and knock on it. After waiting a few seconds the door opens to reveal Sans. "Hey (Y/N)." I smile and wave at him. He steps aside to let me enter his house. As I'm inside his house I look around. "No Papyrus?" I look at him with a blank stare. His happy laid back self turns to a grumpy Sans. I know that look anywhere. Papyrus is with his boyfriend, Mettaton which Sans hates. "Nope just you and me." I flop on the couch as he does the same. He looks at me with a sad smile. My eyes start to water as I look away from him. Sans lets out a sigh and places his hand on my shoulder which makes me look at him. A few tears slipped out but I stayed silent.

"I know it's tough but you have to move on. Yes, I know it is hard when you loved them so much but you just got to know when to let go." He lets a tear out as he keeps a strong smile on his face. A few weeks ago my boyfriend, Brad, cheated on me with my very own sister. It hurts a lot that not only you lose a lover, but also a family member. I never knew she could hurt me like that. The pain is so much to take in. "I'll try." He hugs me as I hug. Sans pats my back and rubs circles to try to calm me down.

"Please smile. I miss seeing it." He pulls away as he nears my face. He starts to make funny faces which makes me smile. Sans always knows what to do when I am a wreck. "There it is. Let's go to the surprise!" Sans yells and holds my hand and teleports us to a blank place. I wobble a bit since I never got used to teleporting and probably never will. Once I actually regained myself I took notice of where I am and who is around me.

"These are some friends, while others are here for the party." He puts more effort in the word 'others' which is probably not a good sign. Then a little version of Sans runs to Sans. What?! "Bigger Sans!" The little guy cheers as Sans chuckles. "Sup buddy." He places the child version of himself on his shoulders. He looks up at me with a lazy smile. "(Y/N) this is Littletale! Sans but, call him Little. Little this is (Y/N), one of my very good friends back at home." I look up from his eyes and look at Little. Little started to blush while starring at me. "Your friend is very pretty." He fiddles with his fingers. My face stiffens and I can already feel the heat rising on my cheeks. I let out a chuckle and pick him up. "And you are adorable." I poke his forehead as he starts to giggle and blush even more. I give him a gentle kiss on the cheek. Little looks at me and hides his face in his hands. Sans and I chuckle as I place him on the ground in which gives him the time to run away.

"Is this a place where different Aus come?" I look at Sans. He looks at me and nods. We walk to where everyone seems to be at. Then another person runs to Sans except he is more....edgy. "UT!!!" He jumps to Sans but he dodges and instead of landing on the floor, he lands me! We tumble to the ground until we stop. The edgy Sans groans and looks at me as I look at him. He widens his eyes and starts to turn red. "I'm so sorry! I didn't hurt you did I?" I smile and shake my head 'no'. I stand up and help the other look-alike of Sans back on his feet. Sans starts to run towards us even though he is already out of breath. "You alright?" I kneel down to fix his attire. He starts to look away from me and growl at Sans. I turn to Sans for an explanation.

"My brother actually likes me and I stole some of Fell's chocolate." He says with a smirk as he stares at Fell which I believe is his name. I stand up and smile at Fell. "Nice job Fell, you tackled a women." Fell rolls his eyes at him but looks at me with sad 'eyes'. I crouch and hug him. "It's fine. At least no one got hurt." I can feel Fell stiff up from the hug I'm giving him. After a few seconds he hugs back warmly. He is such a good hugger [If that even is a word]. We let go and I stand fully so I'm not crouching down. "I'm (Y/N) by the way. It was nice meeting you Fell." We walk away as I glance back at him one more time. His face was completely red until he teleported away. This made me smile as I turned back around to get tackled again by two Sans look-alikes. "Why is everyone tackling me?!" I exclaimed as I try to get up but then get pushed down to the ground. My head hits something hard. I look behind me to see Sans there. My Sans. "Blueberry and Blackberry she's a friend." He drags me away and helps me up. When he helped me do this I got a good look at the two. They were both wearing armor, boots, and bandanas just a different color scheme. I'm guessing Blueberry is the little cute blue wearing skeleton and Blackberry is the tough but cute maroon wearing skeleton. I smile at them. "They are so cute." I said out loud. They both blushed madly and they ran away but Blackberry stopped and looked back. "WE'RE NOT CUTE!" He yelled and ran away with Blueberry. My expression turns to a weird and shocked face.
