HI! This is my first fan-fiction on here. So I watched the new Genderbender episode yesterday then Bad little boy after and it rekindled my love for this couple so i decided to write a fanfic about it. I hope you enjoy! :)

Disclaimer: I don't own adventure time or any of the characters

CHAPTER 1:

"OW! Fionna would you please stop tenderizing my cheek meat?" Marshall Lee asked the adventurer walking beside him as he rubbed his throbbing, slightly swollen cheek.

"You're cheek will continue to get tenderized as long as i'm still ticked off at you." Fionna said with slight anger in her tone, as she punched him in the face once more. Marshall Lee grunted as Her fist again collided with his cheek, twice as hard as the last ten times.

"Gah! Glob Fi, i've apologized numerous times how many more times must I apologize before you quit messing up the money maker?"

"As many times as needed until I've decide to forgive you." Fionna spat with her arms crossed over her chest. Marshall rolled his eyes and sighed.

"I'm sorry, for scaring you by pretending to be dying, I promise I won't do it again."

Fionna glanced at him. He was rubbing his cheek obnoxiously hard. So obnoxiously that she didn't even notice that his other hand was still discreetly keeping Gumball's cream puffs pressed against his chest. she quietly scoffed.

"Alright fine I forgive you. So wanna go on an adventure? I found a nice dark cave we can explore. No sunlight's getting in there whatsoever."

Marshall lee slowly shook his head. "Sorry not today Fi. I'm not really up to exploring, maybe next time."

Fionna frowned a slight hint of disappointment was visible as she shrugged. "Alright I'll walk with you to your home before Cake and I venture off to the cave, but next time you're comin' with me even if I have to drag you." she said pointing a finger at him. He let out a hoarse, nearly painful sounding laugh.

"Alright next time I promise." They walked in a comfortable silence the rest of the way to his house. When they reached his doorstep Marshall Lee turned to face Fionna, placed one hand on her shoulder and looked down at her; a hint of remorse shined in his eyes as he stared intently into hers.

"I truly am sorry for scaring you before Fionna. I never meant to hurt you."

Fionna looked back up at him then softly smiled. "I know you didn't Marsh." She slightly went up onto her tip-toes and planted a gentle kiss on his red, swollen cheek. "I'll see you later you bonehead." She said before turning around and heading onward to her next adventure.

Marshall stood there, a small smile on his own face as he watched her walked away; then a searing pain shot thru his chest. He quickly went inside his house and shut the door. The second his door closed he fell against the wall, his face twisted up in pain. He slid down until he was sitting on the ground. He pulled the cream puffs off his chest, revealing a bleeding wound; right where the wooden spear once was.
