"Hmm, that's okay." Frisk smiled and leaned into Sans' touches. One would think a bony hand would be uncomfortable to feel against the skin, but Frisk had never considered such a thing. As far as she was concerned, being in Sans' lap was just as comfortable as being in Toriel's. His hands were soft and gentle. Though she did have to keep herself from imagining those same hands sending waves of bones and Gaster Blaster blasts through her body. 

Of course, she didn't have to imagine it when it was already burned into her memory. Frisk tensed at that, but quickly relaxed when Sans spoke next. 

It was a joke she had heard before, but she still cracked the biggest smile. Her laugh was tired and soft, yet it was still genuine and happy. As it died down, she nuzzled her head against Sans' chest and laughed again at his next joke. 

She laughed at every joke and pun, no matter how terrible. Sometimes it wasn't the words he said, but how it was said. Sometimes it was simply because it was Sans saying it. A different person could have said the same thing in the same way, and she still wouldn't have found it very funny. Sans just had something about him that spoke to her heart and soul.

Eventually, her chuckles softened and began to fade. Her eyelids grew heavy, and soon she was asleep against Sans. It wasn't a very deep sleep, so the skeleton's next words easily seeped into her mind. Upon hearing them, she cuddled closer to him.

She was going to protect him, too. And Papyrus. And everyone else. If Chara returned, Frisk was going to fight tooth and nail to save her family and this timeline. She'd do it for everyone, but especially Sans.
