Not All Monsters are Bad (UF! Sans x Experimented! Reader)

~Meeting Unexpectedly~

Your P.O.V

I was teleporting to somewhere no one ever knew and then saw Papy blacked out I sighed.

"If only I could remember something from the past...." I thought and snapped out of my mind when I hit the 'ground' with all honest it's not a ground... I'm in my Anti-Void.... I smiled.

"It's good to be back here...." I said a person was floating around the Anti-Void and then disappeared.

"This is where WE always play together Y/n oh~ I miss the good old days when Me, You and THEM played here all day to escape our babysitter all the memories we have  ALL started here in the first place!" A voice said happily I suddenly hit something in my mind like a....

                                                 Memory?

I gasped tears starting to form in my eye "no... NO! NO! NO! THOSE DREAMS CAN'T BE REAL! NO! PLEASE! please.... please.... m-make I-it s-stop! no.... they're.... they're.... they're not... Real..." I screamed crying

         Those smiles, laughs and pranks are..... real? 

                                             no.... They can't be real..... right?

    Please..... Let all of this be a dream I want to wake up from this nightmare....

Narrators P.O.V

Inside the Anti-Void Y/n was crying, Papyrus was still knocked out while someone's watching Y/n from a far.

"I hope she'll remember everything that had happened to her in the past...." He said smiling a bit.

"Welp gotta tell HIM that she's still alive" He said and opened a portal to someone's universe.

In the meantime Y/n was crying to herself until she fell asleep.

~INSIDE YOUR DREAM~

"Y/n~ Where are ya lil' marshmallow?~" A monster said that you always called as 'red' because it's his favorite color.

You giggled under the bed it was past your bed time and your monster mom told you to go to bed early today because you and your siblings are going to the park tomorrow which really excites you.

"Come on Y/n I ain't got anytime for your games" Red said chuckling a bit seeing your F/C night gown under the bed a bit.

"Oh~ I wonder where she is~" Red said sarcastically you pout knowing that he already knows where you are.

You came out of your hiding spot and tackled Red.

"NO FAIR!!!" You said punching him playfully he just chuckled.

"Heh.... Now.... Do you wanna have a...." He said his face turned black looking at Y/n in the eye.

"..... TICKLE time!!!" He said and starts tickling you while you just laugh uncontrollably begging for him to stop.

"R-Red s-stop! HaHahaHahHaahA!!!" You said crying of laughter then he suddenly stopped noticing that you two were on bed while he was on top of you he then blushed red while you just tilted your head out of confusion he then went to your story book corner.

"So what story do you like? Princess?~" He said playfully while you blushed a little.

"I would like a-"
