WD Gaster x Scientist! Human! Reader

"Sans! Stop making your brother float!" You ordered as you reached out for Papyrus. Sans, being the little trouble maker he is, snickered before you held Papyrus. The monsters were free thanks to your invention. It could make a single human soul strong enough to break the power of the barrier and a monster army five times.

It was now being used to help children with weak souls and life threating health problems.

Asgore, Gaster, you little sister Chara, even the whole underground was proud of you. Papyrus snuggled into your arms as your lab coat barley touched the ground. Gaster was sitting on a pillar bottom as his pet Gaster Blaster hovered over the ground next to him.

Gaster couldn't help but watch you with a blush and admiration. Gaster never thought he'd lived to see the day his sons get to the surface, and yet, you gave him a wish he longed for to be complete. You placed Papyrus down before Sans and Papyrus started to play tag.

Gaster's skull creature zoomed after them before Gaster stood up and walked over to you. "(Y/n)," you turned to see Gaster blushing light blue, "I want to thank you." You smiled softly as you blushed light pink. "You don't have to keep thanking me. I did what I could."

Suddenly Gaster had his arms around your waist and your faces inches apart. "Not that. For being in my life." Your blush deepened before Gaster kissed you. Your eyes widened before you kissed back with your arms around his neck.

One of Gaster's hands went into your hair as you leaned onto your toes a bit. "Done already?" You and Gaster yelped to see Chara covering Papyrus's eyes while Asgore and Toriel snickered. "O..oh... hello guys..." You both greeted.
