Small note: I don't know much about the Fionna and Cake series, but I have watched some of it. It's mostly genderbend stuff, right? Like...Marcaline being Marsh Lee. But I did see the entire Adventure time series like...3-4 times.

Ever since Cake had you, things were a bit more complicated. Fionna couldn't always go out with Cake to defeat some enemy that's messing around. And she didn't want to risk bringing you with and you get hurt. But today....there weren't any creatures, so they were able to chill at home.

Fionna was asleep in her room, Cake was here in the living room with you in her lap

Cake: Okay Baby, Tonight, we practice that stretch!

She stretches her arm all the way to the kitchen, grabbing a bottle and putting it on the coffee table, a small distance away from the couch

Cake: Now just reach it from here.

She out her arm around your waist and held on tight do you don't get up. Might as well see if you can stretch like she did
