An Undertale story that came to me. Undertale belongs to Toby Fox. I only own Kelly.

Chapter 5: No Regrets (P x OC; S, W.D., F.)

Kelly gazed out the window as she watched Frisk and Sans playing outside in the snow. A couple years ago, she would have laughed if someone told her that her niece would save a race of kind monsters and she'd end up falling for one of them.

Now, it seemed a bit like a dream, but she smiled all the same. When Frisk had come home and introduced her to Sans and Papyrus, Kelly had been a bit stunned, especially when Frisk told her about Sans being her dad.

It had taken a bit, but after a day around the skeleton brothers, Kelly had warmed up to them, groaning good-naturedly and laughing at some of Sans' jokes and puns, especially when Papyrus groaned too.

She then chuckled as she remembered one of those times.

Flashback…

Kelly was getting breakfast going when Sans walked in with Frisk on his shoulders. "Something smells 'bone'-fide," said Sans.

"It's my aunt's eggsellent cooking," said Frisk, with a giggle.

Kelly laughed. "I can always count on you two for early-morning puns," she said.

"Just don't work your fingers 'to the bone'," Sans said, grinning.

"SHE'S WORKING HER FINGERS TO THE BONE!?" Papyrus cried out as he came out of his room. "HOLD ON, KELLY! THE GREAT PAPYRUS WILL RESCUE YOU!"

Papyrus came running into the kitchen. "Papyrus, wait! I just…," Kelly started to say, but it was too late. Papyrus slipped on the slick kitchen floor that Kelly had finished mopping a few minutes before, and went sliding across the floor towards Kelly, who quickly planted her bare feet on the wet floor and felt Papyrus crash into her a moment later. Thankfully, due to her holding onto the counter when he crashed into her, she wasn't hurt and she didn't fall over. Papyrus was a bit tangled and she leaned down to help him up, but slipped and fell on top of him. When she lifted her head, she was face to face with Papyrus with barely an inch between them. "Oh, um," Kelly stammered, her face turning red.

"Getting a little 'tangled up in love'?" Sans asked.

"Daddy! You ruined the moment!" Frisk protested.

"Nah, I think I rather 'saved it'," he said.

"SANS! You're not helping," Papyrus said.

"Actually, he did," Kelly said, glad that Sans' puns had snapped her out of her stupor. She stood up and helped the taller skeleton up. "Careful. The floor's still a bit slick."

"Slick enough for a 'slip and slide'," said Sans as he set Frisk down and gave her a gentle push. The floor was still slick and Frisk, who was barefoot, began sliding and giggling, pretending she was an ice skater. Kelly chuckled and shook her head.

"What am I going to do with you all?" She asked.

"Nothing, since you've fallen 'head over heels' for Pap," said Sans, grinned hugely now.

"SANS! NO!" Papyrus groaned out, his face turning bright orange.

Kelly's face turned red too. "You've 'cut it close' to the truth," she said, making Sans and Frisk laugh and Papyrus groan again.

Kelly now sighed as she glanced down at the ring on her left hand. Papyrus had proposed to her a few months ago, after she had helped them regain their brother, Gaster.

Frisk had told her aunt about seeing Gaster, but not totally understanding what he was doing there. Kelly had managed to dig a bit more into the history of the Underground and found just a tiny bit of information on Gaster, but it was enough to get her to search his old lab and discovered where he was exactly.

It had then taken just a bit of thinking on Kelly's part and remembering a scientist who was working on teleportation to get her plan in action.

She remembered an explosion and feeling herself falling to the floor, but something caught her and lifted her up before it became very quiet and she was soon laying on a soft surface.

" "

Hearing that strange language, she opened her eyes and saw a skeletal face that reminded her so much of Sans and Papyrus. He looked at her with concern and placed a hand on the left side of her face and she took his hand, noticing how his hands had holes in his palms. She looked up at him.

" ," he said to her.

Kelly gave him a curious look. "You speak in Wingdings?" she asked.

He looked at her in shock and she smiled. "Well, when you write books on the side, you learn all the different fonts," she said. "Who are you?"

" ," he said.

"Gaster?" Kelly asked and then smiled.

When Gaster learned Kelly knew his younger brothers, he asked her to take him to them.

She didn't think she'd seen two happier people than Sans and Papyrus when she came in with their brother behind her. Sans hugged her, thanking her and Papyrus lifted her up in his arms, kissed her soundly and asked her to marry him.

Gaster and Sans were a bit shocked at that, but Frisk ran over to her aunt, begging her to say 'yes'. Kelly chuckled, but then kissed Papyrus, agreeing to marry him.

She now felt someone behind her and saw it was Gaster, who smiled and pulled her into a hug. "Only about a month now, hmm?" He asked, referring to the wedding date she and Papyrus had set.

"Yes," she said.

Papyrus came in, looking lovingly at Kelly. "Kelly, may I ask you something, dear?" He asked.

"Of course, honeybones," she said with a smile.

Papyrus blushed at that. Kelly had taken to calling him that and it made her smile to see him blush. "Well, I, the Great Papyrus, was wondering," he said. "Do you regret anything?"

Kelly's smile faded as she realized what he was getting at and then she straightened up. "No," she said firmly. "I don't regret anything." She then paused. "Except, maybe one very small, little thing."

"What?" Papyrus asked worriedly.

Kelly smiled. "Not kissing you sooner," she said with a smile as she kissed Papyrus full on the mouth, not caring who was watching.

Gaster just chuckled a bit, but smiled too, especially when Kelly dragged them both outside and started a snowball fight that soon escalated to a chase with the three brothers chasing after the two girls, all of them laughing.

Yes, I know, probably not my best story, but still, be nice in the reviews please.

Also, Gaster's translations are as follows:

1. "Are you alright?"

2. "Easy, I'm not going to hurt you."

3. "I am Gaster."

Please leave a review, but no flames!
