Gaster One Shots 3

Fell x Asgore lil sis! Reader

When monsters were sent to the undergrounds and Toriel left Asgore, you were there to comfort your older brother. You were a very caring monster, but with a very dark side. You were a Dreemer after all, don't you think it would be natural to have a powerful dark side?

Anyway, you were walking around the castle when you saw Fell, or Gaster, and your brother, Asgore, training. You smiled and walked in. You've known Gaster since you were a kid since he defended you against some human children. You eyes followed each attack before the two stopped training.

"That was awesome." Fell and Asgore looked over as you smiled. "Oh. Hello (y/n)." Asgore greeted as Fell blushed lightly. "Hey Asgore. Anyway, I was about to say that we need some things at the market!" You informed. Asgore turned to Fell as Fell looked at Asgore.

"Do you mind taking (y/n) to the Snowdin market?" Asgore asked. Fell shook his head before walking past you. "Come on princess." You followed quickly as Fell picked up his bag and threw it over his shoulder. "Do you wanna walk or take a river boat?" Fell asked. "Whatever works for you." You replied.

"We're walking." You snickered and let out a small giggle before Fell glanced at you with a small smile.

Fell watched as you paid for some cheese and bread. Fell then noticed some monsters eyeing you before he glared towards them. You walked over to Fell as you placed the food into your bag.

"Listen, let's hurry up and get you back." Fell whispered as you both walked. "Why?" You whispered back. "It's not safe around here." Fell whispered quickly as he glanced behind him. You nodded before going to buy some (fav/food).

Fell was spacing out a little before he heard you say "Back off sicko!" Fell rushed over as your eyes shined red at a cat monster. "I suggest you listen..." Fell growled. "Oh yeah? Why should I listen to a bag of bones like you?" The cat monster replied.

Fell wrapped an arm around you and brought you close. "Because she's mine." Fell growled as you blushed. "Now, beat it." Fell growled. The cat monster left before you and Fell started back towards the capital. Fell saw you were silent before he took in a breath.

Fell quickly kissed your cheek as you perked. "I love ya. There, I said it." Fell muttered loud enough for you to hear. You took this in for a minute before you smiled and walked closer to Fell. "I love you too." You said before Fell smiled.

...

You do know that there are cameras, right?

And that Asgore has access to them?

...

Welp. Good luck Fell.
