Undertale/Au's x reader 4

You're not going anywhere.

Yandere! Classic sans x reader.

*thanks for the request. Sorry I've taken a few days off because I haven't really felt like writing, and I still have a difficult request to work on, I'm not sure how to end it.

*small quick announcement, Cupid and Hallows birthdays are coming up! Two weeks and two days from now! Yes, they have the same birthday because I made them both at once. :3 Anyway, enjoy!

Warning: yandere, meaning blood, and possessive behavior.

You were homesick, sure you loved the underground, you had gained meany friends, papyrus being one of them.

You've been in the underground for almost a year now, but.. You missed your old home, your friends, your boyfriend, your family must have been worried sick by now.

And, you felt horrible that all of your monster friends had to suffer and be in the dark, they didn't deserve this.

As you walked down the white cold halls, a bad feeling in your gut grew.

Something was telling you to go back, and just live your life with Sans and Papyrus.

The halls were silent, a few monsters had told you the tale behind the prince asriel, it was quite sad.

But that was hours ago..

Your shoes echoed against the golden floor of the judgement hall, after this room, you'd be face to face with Asgore.

You stopped, seeing a short figure standing with its hands in its pockets.

"...Sans?" You whisper.

He comes out of the shadows, his permanent smile had fallen, his eyes to the floor.

"Heh.. Honestly y/n, I didn't think you'd get this far.. "

He sighs. "And the way you say my name it sounds so sweet.."

What? What did he mean by that?

"..And I don't know what got in your head making you wanna leave.. Why would you wanna leave? You've got friends, all of us love you y/n."

His eyes meet yours. "..I love you.. I can't let you leave.."

His left eye burns blue, smoke coming out of it, he lifts his hand, gripping your soul, dragging you to him.

He wraps his arms around your waist and back. ".. Why would you want to leave me? After everything we've been through?"

You sigh and rest your head against his chest. "I feel selfish Sans, if I don't leave, you guys will be stuck down here."

"...I don't give a damn. Who cares if we're down here for years? As long as I have you I don't care where I am."

You felt your heart melt.. But..

"Sans.. That's sweet of you, but I can't do that, I have someone waiting for me up there-

" what..." His eyes turned to black hallow sockets.

"Yeah? Didn't I tell you? I-

" You want to leave because of some loser!? What am I not good enough for you!? The moment you fell down here I knew it was love at first sight! You're telling me you don't feel the same!?"

His grip tightens.

"Sans I.." You sigh. "Sans, I love you and papyrus, but.. I'm not in love with you, you're an amazing friend."

The fire in his eye burns and he growls. "Y/n! You're not listing! I want to be the one you fall in love with! I want to be the one who kisses you goodnight! I want to be the one who you would do anything for!"

"Sans i-

".. And if I can't have you no one can!"

Your suddenly slammed back into the far wall of the judgement hall.

Bones pierced threw your legs and arms.

Sans was suddenly in front of you, his hand under your chin.

"Y/n.. You have no idea how much that hurt me to do.. I hate myself because of it.." He presses his teeth against your lips.

The skeleton kiss only lasted for a few minuets before he pulled away.

"I'll see you soon, my love."

The last thing you saw was a large dragon head thing, before it fired and your soul shattered.

GAME OVER..

*I'll see you in the next timeline.. My love, I'll try again. And you'll see that we're meant to be together."

End. I hoped you enjoyed sorry if its bad, and sad. I wanted to try something new. :3
