The rescue

~ Y/N PROV. ~

I woke up to see Sans was not in bed. Confused, I got out of bed and decided to take a shower. I found my bag by the stairs and grabbed clothes. The clothes consist of a (F/C) T-shirt and jeans. Then I went up to the bathroom and locked the door behind me. I took a shower and got dressed. Once I got out of the bathroom I was greeted by Sans teeth against my lips. Scared and shocked, I jumped back. "Dude! Don't scare me like that. You almost gave me a heart attack!" You tried to calm down, which you did. "Sorry." He replied. "It's okay." Once you forgave him he grabbed your hand and led you down stairs. "So, are you planing anything today?" I asked. "Yea, I did plan actually. My plan is to sit here and be lazy." He replied with a lazy grin. I sighed, "Can I join you?" As I finished my sentence I got a text from Toriel.

Toriel: Hello, my child. I'm wondering if you could pick up Frisk from school. I have to go to the store today.

Y/N: Sure! I would be happy to!

I set my phone down and got off the couch. "Wanna come pick up Frisk with me?" I asked Sans. He pouted and got up. "Sure." I smiled and we walked out the door. We talked a bit on the way to the school, but when we got there it was horrific. I saw Frisk getting beat up. I quietly ran up to the bullies and picked up what I thought was the leader of the group. "So, you picking on Frisk huh?" I said with a creepy grin on my face. He shivered in fright at I stared and waited for a reply. "And what are you gonna do about it? Freak!" I stopped smiling and looked at him. "Well, I think we have a punishment in order. Sans! Help me out here!" I called for Sans as the leader tried to punch me, but I caught it like a bad ass. Sans used his magic to pick up the other kids beating up Frisk. "Now. How about we have some fun Sans?" I asked. He nodded with a creepy smile on his face. I threw the kid to the wall as did Sans with the other kids. "Now, R U N" Sans said with a deep voice. I ran to Frisk to hold her. "Let's get to Tori's house." Sans nodded and held out his hand for me to grab. I grabbed it and he teleported us to Tori's house. Toriel wasn't there, so we treated Frisk's wounds. 'I swear. If this happens again. I'll have to do something worse.' I got snapped out of my thoughts with a hug from Sans. I smiled and hugged back. "What happens if this happens again?" I ask Sans on the verge of tears. "Tori will handle it." He comforted me and tried to keep me calm. I smile at what I was gonna ask Frisk. "Hey, Frisk. Wanna start teaching me Sign?" As I finish up asking she nods fast. I giggle at her determination to teach me. "Okay, let's start. Oh, Sans you know sign too right?" I ask Sans as he nods. "Can ya help teach me?" He nods and joins Frisk in front of me. Frisk signs something and Sans translates, "She said, 'Let's start!'" I smiled and the teaching began.

~Time skip~

After teaching me how to translate most of sign Toriel get back. "Hello, my child What do-" She cut herself off. She had noticed the bandages and bruises. "Sans! Y/N! What happened to my child!" She held with anger in her words. "Tori calm down! We had to save her from bullies, but we got payback and Frisk is fine!" I tried to comfort her. She calms down a bit, but files a complaint to the school. 

Me and Sans started to head home. We didn't talk though. Once we got to Sans' and Papyrus' house we sat on the couch. We sank into the comfort and sighed in relief. "So, we gonna relax tomorrow?" I ask, "Yea." Sans replies. I yawn and lean on Sans. My eyes grew heavy, but before I feel asleep I kissed Sans' cheek. "Good night." I say softly. "Good night, Queen." I softly giggle, "Good night my King." I reply as I fall asleep.
