So it has definitely been a while for me. I can't please everyone but I hope I please a lot of you anyway.

Fionna never had good luck with men. She used to have a one-sided crush on Prince Gumball that lasted for years even though he had politely rejected her several times. Then she sabotaged her relationship with Flame Prince by pitting him against Ice Queen when neither of the involved parties had actually done anything.

So she could not mess up her friendship with Marshall Lee.

Never.

Ever.

They had to stay bros. Nothing romantic could ever happen.

Consequently, Fionna freaked out a little when Marshall suggested they just watch a movie at his place instead of going on an adventure. 'To take a break from the routine', he had said. He was always flirting with her but being in his home with him…alone…at night? That didn't sound like a good idea.

Of course she couldn't reject him. Why would she? They were just friends and she was Fionna, the brave adventuress. This was just another adventure…right?

After pacing around the tree house and concluding that there was nothing to worry about since neither one of them had feelings for each other, Fionna made her way to Marshall's cave as the sun was setting. She reached his home as a few stars began to appear in the sky.

Fionna knocked on the door half-heartedly before opening it. She only knocked out of courtesy. No normal individual would dare enter the Vampire King's lair but she thought of him as a close friend so he's lucky she knocked at all.

Marshall was standing in his kitchen, cooking something on the stove.

"Yo." He didn't even glance up as he greeted her. He knew her smell well and had been taking it in for a few minutes now.

Fionna waved as carefree as she could manage as she closed the front door.

"You're cooking? Weren't we just going to have popcorn or something?" Fionna raised her eyebrows at Marshall as she set her book bag down by the door. She made her way over to the kitchen to see what exactly it was he was cooking. Marshall glanced up for a split second to see Fionna's hair flow behind her as she entered the kitchen and leaned over his shoulder.

"Popcorn isn't red." Marshall threw some more red pepper into the chili he was stirring.

"You can eat stuff that isn't red." Fionna dipped her finger into the chili and licked it clean.

"Yeah, but it does nothing for me. This is something we can both enjoy." Marshall turned off the stove and spun around to grab Fionna by the small of her back. Pulling her into his chest he smirked. "How does it taste bunny?"

Fionna's face turned bright red. "Knock it off Marshall!" She pushed the vampire off her and stomped her way over to the bookcase of DVDs. "Which one of these do you want to watch?" Fionna attempted to calm herself by redirecting the conversation.

Marshall smirked at the flustered blonde. "It doesn't matter. Pick whatever." Fionna picked a random movie and put it in as Marshall brought the chili over. He handed a bowl to Fionna as she re-situated herself on the couch.

"Thanks."

"Yup." Marshall floated above the couch as the movie began. "By the way bunny, where's your hat?" Marshall floated closer and blew in the blonde's ear. Fionna yelped covered her ear with her hand.

"Don't call me that!" She scooted to the end of the couch and curled into a ball as she ate her chili. "I just didn't feel like wearing it today, alright?"

Marshall floated down so that he was actually sitting on the couch with her. That mischievous smirk that was now seemingly permanent to Fionna was directed towards her once again. "That's good. I like it better this way." The vampire reached over and let the long, blond strands of hair fall through his fingers. Marshall just stayed that way until Fionna smacked his hand away.

"HAHA Marshall. No need to make fun of me. Let's just watch the movie." She stuck her tongue out at him. The vampire chuckled before relenting and turning his attention to the T.V.

Fionna was sucked into the movie but Marshall just inched his way closer and closer as the movie reached the ending. By the time it was over, Fionna was practically in Marshall's lap. The blonde didn't realize it until the credits started rolling. Immediately, she panicked and attempted to get up. The vampire just tightened the grip he had on her and nuzzled his face into her neck.

"Marshall! What are you doing!? Let me go man!" Fionna struggled in his grip. Her heart was racing and she didn't like this. What was he doing? They're bros. Bros don't do this! Bros don't make their bros' heart race!

"Come on Fi. Just let me enjoy this for a second." Marshall's voice sounded raspy as he glided his fangs over her neck. Fionna's cheeks flushed red. She was so flustered and embarrassed she didn't know what to do. Sure she was strong but not strong enough to fight off a vampire. The blonde let out a breathy moan when she felt said vampire lick her neck.

Marshall paused out of shock. He looked up at Fionna's face to see it turn even more red, something he didn't know was possible at this point. He wondered what it tasted like.

Fionna took the opportunity to jump out of Marshall's grip and glared at him. "What the glob Marshall!? Could you not tease me for one freaking second!?" Marshall shrugged, the smirk still on his face. Frustrated, Fionna began punching him. "Can't we just play games without you making moves!? Can't we just have fun?"

Marshall held his arms up to shield himself from the punches. Hissing, he tackled the blonde and began tickling her. "I was having fun Fionna. You weren't?" Fionna couldn't answer between her gasps of air as she laughed. Her punches began to falter as she attempted to tickle him in retaliation. The tickle fight progressed into a wrestling match with Fionna straddling the vampire king on his back. She twisted his arm back, making him hiss in pain.

"I'm having fun now but I'm a little disappointed. Is that it Marshall? I thought you were strong! Hahaha." Fionna laughed triumphantly but was interrupted as the vampire disappeared and reappeared behind her, holding both of her arms with one hand at her back.

"I never meant to disappoint. How about a few video games so things are a little more fair….for you I mean." Marshall chuckled as he ghosted his lips over neck. Fionna had frozen up so Marshall continued towards her shoulder, slowly pushing her shirt down with his fangs.

"Okay, okay! Video games it is!" Fionna finally spoke up, frantic to escape the situation. Marshall laughed and let go. Fionna breathed a sigh of relief and stared at the vampire.

"Alright then. You pick. Don't need you moping around as a sore loser before we've even started." Marshall smiled and floated back to the couch. Fionna growled at him before making her way to the bookshelf again. "Oooh. Feisty. Do it again." Marshall laughed. Even though he couldn't see her face, he could see her neck turning red.

Angrily, Fionna picked a game and started up the console. "Let's go. I'll beat you fair and square." She stuck her tongue out at the vampire.

Marshall took the other controller and floated closer to the T.V. "Sure bunny. Whatever helps you sleep at night."

Not too great I know but I am a little rusty. I'm working with the little bit of personality that was shown in the gender bent episodes of Adventure Time but this chapter got a little more serious than I intended. No worries, this will be good! I swear! Stick with me people! Review please! :D
