Frisk and Lancer loved pranks, though they were never as good as they thought they would. They were always something small, like hiding other people's things or messing up someone's color coded closet by moving one red shirt into the blue section (which the person considered awful even though others didn't see the problem).

They had to stop their prank for a little while when Lancer went on vacation with his dad and bonus dad for a few weeks over the summer, but when he got back, they were determined to make the ultimate prank, their best one yet.

That morning, Toriel was in the kitchen making coffee when Frisk walked downstairs. She smiled at them and patted their head when they walked over to her.

"Good morning, Frisk," she said.

"Morning, Mom! I had a question," they started, "could I go hang out with Lancer today?" They were very eager to hang out with their boyfriend today, especially for the plans they had.

Toriel nodded, "of course! Just make sure you're home before seven. You and Kris are going to Asgore's for a few days, and he wants to take you both swimming tomorrow." Frisk nodded and immediately went to go upstairs, but Toriel stopped them. "Hold on a second. You aren't going anywhere without breakfast first. Could you go wake up Kris for me so they can come eat too?"

Frisk nodded. They forgot that Kris wanted to wake up early today. They were going to spend the day with Ralsei, Susie, and Noelle. Frisk wasn't sure what they had planned, but they didn't really care. It's Kris's life, who were they to snoop in it? 

They walked upstairs and opened their bedroom door, seeing Kris still fast asleep. Their leg was hanging off of the bed while the other one was under the blanket. One of their arms was underneath their pillow, supporting their head, and the other was hanging over their stomach. It looked pretty uncomfortable to Frisk, but Kris always slept like that, so at least they were comfortable.  

Frisk walked over to them and poked their face. "Kris, wake up." Kris groaned and rolled over, so they were facing away from Frisk, and pulled the blanket over them and over their head. Frisk sighed and tugged at the blanket in an attempt to get it off of Kris, but they had an iron grip on it. Yeah, that wasn't going to work. Instead, Frisk just started to rapidly shake them. "C'mon, Kris! Mom wants you up! She made chocolate chip pancakes!" 

This got Kris's attention, seeing as they slowly pulled the blanket away from their face. They held up their hands to sign to Frisk, "are they done?"

Frisk nodded, "they will be in about a minute. But that's enough time to get down there and get some juice before Mom lets you get some. Besides, she won't let you touch them if she thinks they're too hot." Kris sighed and sat up, rubbing their eyes and stretching a bit before pushing the blanket off of them and walking out the door. Victory! Frisk thought before they followed their sibling. 

The small family sat together at the table, just talking about plans for the day as well as Toriel gripping at Kris for not having a decent sleeping schedule.
