             •~~Thunderstorms~~•
Sans left to go visit Toriel, he said she needed help with something. Now, I'm sitting on the couch watching the news. They said it would be severe thunderstorms. I looked outside an saw the incoming darkened clouds. I've had a bad history with thunderstorms. Mom and Dad was never around to comfort me and tell me it's okay. Instead, they looked at me and tell me to suck it up. I decided to text Sans and let him know.
(Y/n): Sans, a thunderstorm is on its way.
Sans: oh really? Well thanks for letting me know it's starting to drizzle over here.
(Y/n): oh no problem.
It is a problem. Sans knew about my fear so did he just forget about it that fast? Am I not important to him? A flash of lighting filled the room and the lights went out. Not soon after a crack of thunder sounded. I gave out a shriek and started to tear up. This is so childish of me. I don't need to be scared.......but why am I scared? I've dealt with this my whole life. I got up and walked over to the bed room. I closed the door and went to the closet. I escaped there and started to cry. I need someone here to comfort me. I need Sans.
Sans P. O. V.
After (Y/n)'s text I informed Toriel on what's about to happen. After I did she seemed to ponder on something for quite a long time. Frisk had woken up from her nap and played with my hand. The fascination of a hole in my hand never ceased with her. I lifted my hand and she flew up with it. She giggled at being lifted up.
"Isn't (Y/n) afraid of thunderstorms?" Toriel asked.
I put Frisk softly on the floor and my eye started to glow.
"Shit! I totally forgot!" Sans said.
"Language!"
"Sorry!"
I bolted out of the house and ran to the one (Y/n) and I shared. I passed large puddles and the rain started to get heavier. I pulled my hood up and over my head as I ran. The house was in view and I rushed to the door. I fumbled with my keys until I got the right key. Opened the door and called out (Y/n)'s name. I closed the door and ventured the house. It's no telling how long she was truly alone for during this storm.
"(Y/n)....babe, if you can hear me please answer me.." I called.
I opened the bedroom door and heard a choked out sob followed by a hiccup. I stood in front of the door and placed my forehead against it.
"(Y/n), I'm sorry.." I said.
The sobs softened until thunder sounded throughout the house. I opened the door and pulled her into a hug. She gripped my rain dripped jacket and hugged me close. I picked her up and sat on the bed. I placed her on my lap and she was struggling to steady her breathing.
"I'm sorry." I whispered.
"A-about wh-what?" (Y/n) asked between quick breaths.
"Forgetting about your fears. I call myself your boyfriend but I forgot the one thing you are deeply afraid of. I'm so sorry.."
"It's okay, you can make mistakes from time to time." She said, finally regaining her breathing pattern.
I hugged her close as I fell backwards into the bed. She gave a soft giggle at my childishness and yawned. We fell asleep shortly after.
Bonus:
"Nope!" I called at the distressed Sans.
"C'mon! Give me some!" He pleaded.
"No! It's mine!"
"Can't you share?!"
"Hmmm nah!"
He was begging for some pocky that I bought a few days ago.
"Why?" He asked.
"Because you forgot about my fear." I answered.
"What?? I thought you forgave me!"
"I did, but you needed to be punished."
"UUUGH!"
