underfell sans x suicidal reader

(*warning rape themes included*)

You were walking back to your classroom after you took a quick bathroom break, when two boys in the same grade as you walked up behind you and pulled you into an abandoned classroom and began to take off your clothes. Before you could scream they gagged you with a cloth and began discussing what they were going to do.

Boy one- I wanna take her virginity ma-

Boy two- hell no! We're just doing her in the ass that way it will be harder to trace~

Boy one- then what do I do? She only has one ass hole....

Boy two- you will go second unless.... we could both fit?

Boy one- sweet man.... Let's do this!

They both lined up at your back entrance and forcibly pushed themselves into you. Tears lined at the edge of your eyes as you let out a yelp. They thrusted at almost inhuman speed as your innards began to throb. You were now fully crying and on the brink of passing out when they both grunted and came inside you.

Boy two- Aww look at her, bleeding and crying! We hit the jackpot! Now get dressed and hurry back to your class and you better not tell anyone about this or we will do it again.

As the two boys began to walk out the first boy turned around.

Boy one – and you WILL lose your virginity to me! But don't worry I'll be gentle~

-Time skip to your house (by the way you live with the underfell bros on the surface)-

(Y/N)- Hmm their not home yet, oh but the groceries are here I better put them away.

You squatted down to grab the bag but was met with a sharp pain in your lower back area.

(Y/N)- Oww! Fuck it still hurts!

Your phone began to ring; you see it was an unknown number but answered it anyway.

(Y/N)- Hello?

Another person- we know you liked it (Y/N), and we plan to do it again! Don't worry it won't only be your ass that hurts after~

(Y/N)- No, no please what did I do too---

Another person- oh you know accepting those things as your friends and family, maybe we should go after frisk too, what do you say?

(Y/N)- No, leave her alone! I will do anything....please don't hurt any of them, please!

Another person- well then DIE, just die that is all we ask then we will leave the others alone...

You began to cry.

(Y/N)- Okay, I will do it, but if I hear that you have been around them then the deal is off...

Another person- no we won't do anything to them if you complete your task, we already know that you were already suicidal, you even cut! You even tried to commit suicide but you could not build up the guts to do it.... Do it now and they will be safe....

He hung up, your head was full of questions like how did he know what you thought and what you have done in the past even what you tried to do. And after all of this, you were even more suicidal, you knew that if you did kill yourself the raping would end, the bullying would end and you would be happy again. You walked into sans' room and grabbed sans sleeping pills not noticing that sans was awake and watching the whole time knowing what you were planning but he waited until you were gone to call papyrus. You walked into your room ready to write a suicide note for papyrus and sans explaining everything.

-back in sans' room-

Sans- hey boss we got a problem...

Papyrus- sans I am at work what is so important that you had to call!

Sans- it's (Y/N), I think she is going to commit suicide...

Papyrus- what! I will be home soon keep an eye on her! And that is an order!

Sans- yes boss, just hurry...

-in your room-

(Y/N)- *just the whole bottle, then it's all over* *huff*, I so sorry sans I love you, love (Y/N).

You finished the letter and placed it on the bed near where you were going to lay down and die, you sat up and swallowed the pills.

(Y/N)- goodbye world...

-in sans' room-

Sans- shit her soul! It's fading!

Sans quickly ran into your room which was next door to his. He saw you laying down slowly having a small seizure. In an instant, sans lifted your head and shoved his boney fingers down your throat making you puke on the side of the bed avoiding sans, he did it again, and again, making sure it was all out of your system. You finally opened your eyes to see sans holding your crying. You remembered everything you tried to do and saw how bad it hurt sans, the one person you loved and wanted to protect the most.

(Y/N)-s-sans? Why did you stop me?

Sans- I stopped you because I need you! Why did you do it!?

(Y/N)- Sans, It was to protect all of you and frisk....

Sans- what happened that made you think you needed to protect us?

(Y/N)- Well, there were these two boys from my grade and they...they....

Sans- what the hell did they do?!

(Y/N)- They raped me and then they called me and threatened to do it again. They even threatened to hurt the rest of you if I did not do this....

Sans-w-what? Where did they do it...?

(Y/N)- In the ass, they did not want to leave any evidence....

Sans- did you enjoy it?

(Y/N)- Hell no! It hurt and they both did it without mercy.... I wanted to do that someday but with someone else...

Sans- I can't believe this! How did you endure it?

(Y/N)- I thought of you... you're the one I wanted to do that with...

Sans-what.... me?

(Y/N)- You were the only one I could think about...

Sans leaned near you and began to kiss you and hug you.

Sans- I love you too if that is what you meant....

(Y/N)- It is... and I love you to sans...

Sans began to cry.

Sans- don't ever do that again....please...

(Y/N)- But what if they try it again...or they hurt you guys...

Sans- boss and I will take care of them underground style...

Papyrus came through the door of your room to see you sitting upright but passed out from the pills effect.

Papyrus- human are you okay?

Sans- she is boss I got her to throw up the pills...

Papyrus- did you take her to alphys?!

Sans- sorry boss, I just wanted her to be safe so I took action!

Papyrus- well let's get her to alphys and make sure she is safe....

Sans- yeah boss good Idea...

Papyrus- why are you blushing in a situation like this?!

Sans- well I just found out she has the same feelings for me...

Papyrus- well I don't care now let's go I want to hear the story on the way to alphys...

Sans- oh yeah and boss we got some kids to kill once we confirm she is okay...

Papyrus- I will decide that after I hear the story... but if anything or anyone hurt her they are good as dead!

Sans- oh trust me you will want to kill them... for her...
