(stalker reader x Blueberry Sans next part will be reverse roled yandere Blueberry x reader)

(y/n) (l/n) the most recent human to fall down Mt. Ebott. She had a sick facination with the small blue clad skeleton. It started so innocent with him aiding her when she was nearly frozen to death. Now she takes every kind act as some sign that he loves her.

I was born only to share my love with you

what is this thrill I feel deep within my heart

still I whisper through these thin walls so sweetly

you are mine and we will never be apart

She had a shrine in her home. Pictures of him were hung on every wall. Most of them were taken without him ever knowing.

I will find all of your lovely little secrets.

Every one; discover all there is to see.

And if I could feel the curves of your body.

Touch it so that you would lust only for me.

She traced her finger across a photo of him sleeping.

A few days later she made a new discovery.

Oh my my!

do you have a guest in your arms?

Such a cute little thing with all those golden curls.

Tell me, tell me darling how much you love her.

Maybe I will slaughter your precious pretty girl.

Blue was walking with a bunny girl with bouncy blonde curls.

(y/n) hated the look that girl was giving him. She despised how close in proximity they were.

Blue belonged to only one woman, so it was time for Ms. Bunny to go bye bye. 

I will burn in a fire photographs of your desire!

I wonder if she knows of me?

You can use and abuse!

Do anything I won't refuse!

To prove I love  you more,

don't you see?

(y/n) had the bunny strapped to a chair dead from hours of torture.

I'll hold you close.

I''ll break you in.

Let's raise a toast to our final sin.

(y/n) smirked from her balcony, sipping her wine as she watched her precious Blueberry train with Alphys.

Why is it you're crying?

What's wrong, baby?

What the matter, lover?

Don't worry your little head.

I'm only holding the box i built for you.

That I can keep forever with me once you are dead!

Sans sat crying over the news that Ms. Bunny was found dead.

(y/n) merely stood there giggling as she held a box with Sans' name on it.

It was i who placed that gift at your door.

I hope it was everything you're asking for.

A bloody kitten head just for you.

Who loves cats as much as you do.

(y/n) went to the Tem village and slaughtered enough of them to fill a small box with their heads.

I will burn in the flames every trace of her name!

I wonder if her life's clock still ticks?

"I love you" is you so clich";

filthy words that you've betrayed!

I know it makes me feel like i'd be sick!

Months after Bunny's death, Sans came crawling to (y/n) with this forced and faked affection of love. It angered her to no end.

I'll make you see;

force you to be

In love with me eternally.

In the end she made it clear. If he would not love her, then she won't allow him to love another.

Papyrus and many of the royal guard members searched high and low for Sans.

(y/n) just sat in her chair kissing his severed skull while his scarf was tied around her neck.

"I told you Blue, you are mine and we will NEVER part"
