A Certain Obsession- Undertale Sans X Reader

The Date?

(After a little while of Undyne adoring you two, she left to check on Alphys, she told you that Alphys said you are 17 now. And soon to be 18.)

You walk over to your bedroom
The sunlight escaping from the curtains and giving light to the splash of colors on your walls. You lye down on your bed. Still not fully believing what has happend to you. 'Am I really not a kid anymore?; Am I really seventeen?; Or is this all just a dream?' . These thoughts filled your mind. Making you feel hopeless. Then you could hear foot steps aproaching your door.
Then you heard a knocking sound. "Come in!" You said.

The door opened to reveal that it was Toriel. "Hello my sweet child. My, so it's true. Look at you!" She came to you, with open arms. Hugging you tightly. "Your so tall! Ohhhh, and so beautifull. Just like you always were. I know, this may be rough for you. But you'll manage." Toriel, Your mom, always giving you good advice. Making you fell like the most happiest girl in the world. "Thank you. Ma." You thanked her.

But her smile faded, and tears filled her eyes. "M-My child. P-Promise me that I will always be your mother. No matter what age you are. Okay?" She sniffled. Putting her hand on her face. You hugged her softly. "Ma. Don't cry. Of course you'll always be my mother, no matter what."

*You tried your best to make Toriel feel better. She stopped sniffling. It seems that it worked.

"Thank you, Frisk." She broke the hug and swiped her tears. "Now. Enough sadness, Look at you! You must be so uncomfortable in that tight clothing! I must make you a new sweater. And a new pair of shorts!" She claimed. Dragging you towards her home. On the way out, you see Sans playing C.O.D.

"Bye kiddo...... W-wait!" He ran up to you with a piece paper in his left hand. "Tori, uh, may you--" "Yes Sans. I'll let you two be, once your done Frisk, come to the ruins." It seemed like Toriel knew what he was going to say. So she walks off. Once she was a fair distance away. Sans looked at your and you looked at him. "Uh....H-Here. Be there at 8." He told you while giving you the piece of paper. Then he ran towards his room and slammed the door shut. 'Weird.' You thought. Then you opened up the note. You knew the secound you saw it that it was Sans' writing. Always very sloppy. It said -

Dear Frisk,

Uhm. So kid, since your a teenager and all now. You can date people....Right? So uh....Meet me at Grillby's Friday night, Okay? It's not a date or anything but---, okay, maybe it is, heh, but, see you there kiddo. No need to look fancy.

Sincerely, the bone man.

You gasped at the ending. Sans Does like you! But the question is....Do you really like him?
