Fionna was sleeping when she heard a noise outside. She tried to wake Cake, but she wouldn't budge so Fionna went alone. She took her sword and went downstairs. "Hello...?" She called into the darkness, hoping nothing answers back. All of a sudden she heard a voice behind her.
"Hey there.."
She gasped and turned around, swinging her sword, blindly. "GET AWAY!"
"Woah, woah, woah. Watch where you swing that thing." The voice said.
Fionna gasped at the familiar sound.
She ran and turned on the lights revealing Marshall Lee. "You butt!" She said punching him.
"Ouch!" He rubbed the place she hit.
"Why are you here? And why did you purposely scare me?!" She asked, cheeks brightening.
He chuckled and said,"I came to take you out..."
"Huh?"
Before she could protest he grabbed her a d flew out of one of the nearby windows. He took her to his house in a huge cave. When he let her down she punched him again.
"Ow!"
"Why'd you take me here you freak?!" She shouted.
He looked down to the side with a frown.
She gasped and said,"oh glob! What's wrong?"
"It's just..." He sighed," it's my birthday and I have no one to celebrate it with so.."
She gasped and thought for a second then took his hand. He gasped and looked at her. She smiled and said,"I'll celebrate with you!"
He smiled back. "Thanks.."
She took him in and they danced while Marshall played his Bass. They ate pizza and watched heat signature. Before they knew it they were in bed, cuddling.
"Marshall?"
"Mm"
"I love you.."

"Marshall?"
All of a sudden he sat up and embraced her. "Marshall?! What the glob! You-"
"I love you too.." He said in whisper.
"Wha-what?"
He released his grip and looked her in the eyes. "I said I love you" he touched her cheek and kissed her lips. After making out for awhile, they stripped down.
"Is it okay?" He asked, looking in her eyes. She nodded and kissed him. They made love and fell asleep in each other arms.

The next day Fionna woke up in her bed, confused. "How did I get here? Was that all just a dream.."
"Hey gurl!" Cake called from down stairs. "You have a visiter."
"Okay" she said back before getting out of bed and changing her clothes. She went down the stairs saying,"who is it-" she stopped seeing Marshall.
"Good morning princess" he said and showed his tongue.
She blushed and said angry,"what are doing here?!"
He chuckled and said,"you forgot this." And tossed her something. she gasped and caught it. She looked what was in her hands, confused and gasped and turned around.
Cake came in and said,"hey guys who's hungry~?"
Fionna ran back up stairs and cake gasped. "Where are you going!? What did you say to her?!" She directed her second question to Marshall.
Marshall chuckled and said,"nothing...she probably forgot to put her underwear on."
Cake looked at him weird. "Whaaaaat?"
He chuckled. "Nothing. Nothing."
