I didnt mean to.... Uf)Sans x Reader

Today you and sans were arguing about who was cooking. Reason why one of you had to cook was cause papyrus had to go on training for a week. "Sans just go cook!" You threw your arms up "Why don't you go cook!" Sans glared at you "I've been cooking more than you!" You cross your arms "Well if you've been cooking more than why don't you cook, doesn't women's cook for guys anyways" "Sans just go cook already we've been arguing this for way to long! Why can't you just cook just this once and not argue with me about cooking." Sans got up and walked passed you bumping your shoulder making you fall down as sans get into the kitchen he starts cooking. You huffed and got up and dusted yourself. You sat down on a chair inside the kitchen watching sans cook just in case if he burns the food.

<BOOM FOOD READY!>

As you both started eating the food you both didn't talk to each other not wanting to have another argument. When you got up to get more food you accidentally drop your entire plate full of food. "Oh my god sans I-" sans got the wrong idea and got mad and strikes a bone into your heart making you lose 19 HP. Sans eyes widen in surprise. He didn't meant to hit (y/n) but that it too late he already done it and now it was his fault he hurted (y/n). Everything got dark as your slowly sink into darkness.

<later that day brought you by Us sans
a/n: wait how did you-?
Us sans:shhh we'll talk about this later>

You could hear yelling "SANS YOU COULD'VE KILLED HER!?!" It was papyrus voice but why was he yelling? "I know paps I didn't mean it, I just...I just don't know why I did it" now you could hear sans voice you open your eyes and saw sans and papyrus. They both gasp and ran towards you as they hug you "OH MY ASGORE I AM SO GLAD YOUR ALIVE I THOUGHT YOU'VE DIED!" "(Y/n)! Your alive I'm so relived!" They both let go of you to give you some space. Then papyrus elbows sans "ow..oh yeah..(y/n)..." Sans comes close to you then looks down "I'm sorry I didn't meant to hurt you I-" you've noticed he was crying and you suddenly hugs him "it's okay I forgive you I know you didn't meant to so there's no need to apologize to me" you say as you gently pats sans head (or skull?) sans started crying even more and hugs your tightly around the waist "I promise you I *sniff* I won't hurt you ever again".

KABOOM HOPE YALL ENJOY!
