Mouth to Mouth (Bubbline)

(art does not belong to me)

CONTENT WARNING: This fanfic includes smut.

Okay, I'll be honest; I have no idea what the hell the game they're playing is actually called, but it's the one where you try to transfer a piece of paper from your mouth to someone elses using only your lips. This is also my first time writing a Bubbline fanfic, so bear with me.

Bonnie and Marceline are having a sleepover at Bonnie's house. They come across a video of people playing mouth to mouth, a game where you try to transfer a piece of paper from someone else's mouth to your own with only your lips. The game peaks Bonnie's interest, so she asks Marceline to play.
The twist is that the winner gets to decide what the do for the rest of the night.
