Sans POV:

"R,really?" I asked. She nodded while blushing. My smile grew wider and wider. I hugged her tightly and she giggled. "So... what does that make us now..?" I asked. "Well... Sans the skeleton. Will you... go out with me?" I smiled widely. "I'd love to." We both giggled again.

1 week later...

Frisk POV:

"Bye Sans! Bye Papyrus!" I called as I left the house with Toriel and Asgore. "I hear someone is going out with a certain pun making skeleton?" Toriel asked and I blushed. "I'll take that as a yes." She giggled and I laughed slightly as well. "I have told the skeletons that you might have to stay with them again next month because we've got another... boring... trip..." She grumbled. I laughed. "That's alright!" I smiled making Asgore laugh and ruffle my hair. It's growing quickly. When I first arrived it was at my shoulders but now it's coming up to my elbows.

1 month later... (I know there are a lot of time skips but bare with.)

Third Person POV:

Frisk sat in the lounge when Toriel and Asgore walked in. "Lemme guess." She said while staying upside down. "Another trip?" They both sheepishly nodded. "Well stay safe on it." "We should be telling you that." Toriel laughed. "The skelebros do know that I'm coming over today, right?" They looked at each other. "They know..." Toriel began. "It's this month." Asgore finished. "Perfect." She smirked. The two goats stared at her. "That means I can prank them!" "By doing what?" Toriel asked her. She then explained it to them.
Frisk POV:

This is gonna be fun. I quickly got the costume and everything I needed before walking to the skelebros house. As I did I was practising my voice, trying to make sure that they wouldn't recognise it. Once I arrived I hid behind a bush and got the costume on. This is gonna be so much fun. He he he.

Third Person POV:

"Hey Sans!" She called while she changed my voice so he didn't recognise it. "Yeah?" He asked, from the other side of the door. "I've got a joke for you!" "Fire away." "Why did the chicken cross the road?" "Why?" "To get to the skeletons house." He laughed slightly. "Knock knock." He raised an eyebrow as he heard a knock at the front door. He walked over. "Who's there?" He asked. "The chicken!" Sans opened the door to find Frisk dressed as a chicken. He blinked before he burst out laughing. (shout out to xSkyrimgirlx for telling me the joke! Please check out her stories they are amazing!) "Is this the day you're living with us then?" She smiled and nodded. "Alright." He laughed. "Get that chicken suit off though. Or you'll really ruffle my feathers." She laughed as she walked into the bathroom. A few minutes later she walked back out in her normal clothes. Sans grabbed her wrist and spun her round and she laughed. He pressed his teeth to her cheek which they both blushed at. He pulled away. "Can't wait to tell Paps." He said while winking which made her laugh. "Actually...."

With Papyrus...

"The chicken!" Frisk yelled while jumping through the door as the chicken. Papyrus wasn't amused. "Is she not tickling your funny bone?" Sans asked. Papyrus looked at him. "Aw come on. Is she ruffling your feathers?" With that Papyrus rage quit and walked into his room leaving the couple to laugh and laugh. "It's good to have you back kiddo." He said. "It's great to be back." She smiled. They went, hand in hand, to the kitchen.
