Hi, everyone! This is a Marshall Lee/Fionna story.

Ever since I saw the episode "Bad Little Boy" I've been inspired to write this story.

Anyways, Enjoy!

It was a wonderful afternoon in the land of Aaa. The sun was shining bright and the birds were chirping sweet melodies. Yeah, it was a perfect day.

Until…

"AHHHHHHH! FIONNA, HELP!" Prince Gumball yelled in distress as he was being kidnapped, once again, by the Ice Queen.

"Ha ha ha ha ha ha ha. Scream all you want, my pretty prince. That tomboy won't save you now." Ice Queen cackled in victory as she carried him while flying through the sky.

"Who are you calling a tomboy, ya witch." Fionna called out as she ran after the Ice Queen with Cake trailing behind her. "Let Gumball go!"

"Make me!" The Ice Queen used her blizzard attack on Fionna.

Unfortunately for her, the blonde-haired girl dodged it, jumped in the air, and kicked her right in the belly. The kick was so hard and painful that it made her drop the candied prince.

"AHHHHHH, HEEELLLPPP!" Prince Gumball yelled as he was falling through the sky.

"I got cha, baby." Cake said, extending herself larger so he could land on her back.

The pink prince landed on the magical feline with a soft thud. He watched with awe as the blonde heroine fought off the evil ice witch.

"Get outta here, Ice Queen! We don't want your ugliness here!" Fionna said to a bruised-up ice witch.

The Ice Queen composed herself and glared at the blonde-haired tomboy. "Grrr, don't think that you won this fight, ya brat! Next time, I will be back and I will take Gumball and make him my king."

"Aw, stop talking all that nonsense and go suck an icicle." Fionna scoffed, waving her off like she was a nobody.

The Ice Queen let out a furious growl as she flew away in defeat back to her ice kingdom.

"Glob, I thought she never leave." Fionna turn around to see Cake carrying PG on her back. "Gumball, are you okay?" she asked with concern.

Prince Gumball dismounted off of the magical cat's back. "Yep, I'm okay. I just glad that you came in time to rescue me." He went over to Fionna and gave her a hug, which made her blush. "Thanks for saving me….again."

"Aw, it was nothing. Just doing my job." she said, returning the comforting hug.

They pull apart from the hug and gazed into each other's eyes.

"My my, Fionna. You look so beautiful in the sunset." Prince Gumball complimented sweetly.

"I…I do?" she questioned with her head cocked to the side.

"Of course, you're the most beautiful and wonderful person that I ever saw." he replied.

The blush returned on her cheeks. "Oh, Gumball. That is so corny. Are you saying that just to be nice to me?" Fionna asked.

"Oh heavens, no. I'm saying that because….I love you." the candied prince replied.

"W-W-Wait a minute. You…You love me like a guy friend or a girl friend?"

"Ha ha, a girlfriend, silly. I care about you, Fionna." He grasped her hand and kissed it. "And I wanna be with you."

Fionna's eyes welled up with tears, happy that the candied prince loved her as much as she secretly loved him.

"Oh, Gumball." She buried her head into his chest. "This is the raddest moment of my life. I love you too."

The human adventuress gazed up at him and they bought their lips together for a passionate kiss. The kiss got a little too intense when Fionna wrapped her arms around his neck and moaned into his mouth. A certain cat, who was watching, decided that it was time to break it up.

Cake cleared her throat. "Excuse me, lovebirds. But as much as I love a happy romantic ending, it's time for us to go. It's getting dark."

The couple looked at the sky and saw that it was nighttime.

"Oh, well. It's getting late. Time for me and Cake to go." Fionna said sadly.

"I know, Fi. But please, come to my castle tomorrow. I got a huge surprise for you." Prince Gumball said as he caressed her cheek.

"Okay, I will." she reluctantly left his embrace. "Bye, Gumball." she waved at him.

"Farewell, Fionna, my love." the pink prince waved back to her as he walked back to his candy kingdom.

Fionna and her best friend, Cake, walked back home to their treehouse. When they entered the house, the now 16 year-old teen plopped down on the couch with a big, Cheshire-cat grin on her face.

"I can't believe it, Cake. PG said that he loved me! Not as a guy friend, but a girlfriend." Fionna exclaimed with excitement.

"Yeah, I know, girl. I was there watching the whole thing. It's no doubt that Gumball loves ya, Fi." the cat stated, also plopping down on the couch.

"Yep, and I can't wait for tomorrow. I wonder what PG has to give me?" she asked herself out loud.

"Maybe he might give you some roses or a box of chocolates, or maybe something cliché like that." Cake simply answered.

"You know, you may be right, Cake. But I'll just find out tomorrow because right now, I'm totes tired." Fionna yawned while stretching her arms.

"*yawns* Me too, suga. It's time for bed." the magical feline stretched herself up the ladder to her small, purple cat bed that was about two feet away from Fionna's bed. "Ya coming to bed?"

"Nah, not right now. I'll be in there shortly." the blonde-haired girl stated.

"Okay, Fi." was all the magical cat managed to yawn out before she went to sleep.

While her best friend/sister was off to dreamland, Fionna got off the couch and decided to prepare herself for bed. She put on her pink bed shirt and shorts, took off her bunny hat, and began brushing her long, Rapunzel-like hair. As she was brushing her blonde hair, she heard a knock on her window.

"Huh? I wonder who that could be out late at night?" Fionna questioned curiously as she placed her brush on the table and went to the window.

When the adventuress went towards the glass windows, she was shock to see who it was.

"Marshall Lee! What the stuff are you doing here?" she asked, unhooking the latches so she could let the vampire in.

He floated in and landed on his feet. "Sup, Fionna. Dang, girl, you look different without your hat on. Kinda like a hairy monster or something."

"You didn't answer my question. What are you doing here?" she asked again with a frustrated sigh.

"Oh, nothing. I just came here to mess with you and Cake. By the way, where is that little, scaredy cat?" he asked while searching the room.

"She's sleeping." Fionna simply replied. "So please don't bother her. We just had a rough, busy day dealing with the 'Ice Queen kidnapping PG' situation again, so we really need to get some shut-eye."

"Wow, it sounds like you had a sucky day. I don't even know what's worse? Kicking the Ice Queen's butt or saving that wussy Bubba." Marshall Lee said with a smug laugh.

"Shut up, Marshall! Don't talk about Prince Gumball like that!" she snapped in anger.

"Oooo, I'm sooo sorry. I've shoulda never said that." he said sarcastically, which made Fionna even madder.

"Why do you have to be a flippin' jerk all the freaking time?"

"'Cause it's just the way I am, sweetheart." Marshall answered in his deep sexy tone that made her blush and her anger suddenly disappear from her tone.

"Well, still…." The blonde-haired girl twiddled her fingers and hid her blush from the handsome vampire. "….you don't have to talk about PG like that."

"Why can't I. It's not like you and him are a thing, right?" he unknowing said, which made her blush increased ten-fold.

"Oh….my….Glob. I was right. You two are an item. I cannot believe this. Someone please pinch me because this must be a dream." the Vampire King teased in an amusing tone.

"Ha ha, very funny." Fionna said sarcastically while rolling her eyes at him. "But anyway, I gotta go to bed, so you should be on your way."

"Alright, alright, Fi." I can see where I'm not wanted." He flew to the opening of the window. "But before I go…" Marshall quickly swooped down and slowly licked Fionna's bare neck.

"Eeewwww, gross! Marshall Lee! What the heck, man!" the heroine groaned in disgust as she tries to hit the vampire, but misses terribly.

Marshall Lee just let out a deep laugh before he left to fly back to his underground cave.

"Grrr, darn him. He's so immature." Fionna rubbed the spot on her neck where he licked her and she unsuspecting shudder in pure…excitement? Pleasure?!

"Ugh, heck no! what am I thinking? I have feelings for Gumball, not Marshall." Fionna scowled herself. "But still, it did felt good when he….GAAAHHHH! I really need to get some sleep 'cause I'm clearly not thinking straight."

The blonde-haired adventuress closed the window, climbed up the ladder, and got in her bed, where she slept peacefully.

So, what do you all think!
