Fionna laid in bed.

Her morning consisted of convincing Cake to go without her to Prince Gumball's party. Cake was adament about her getting her "buns" out there, but Fionna had to stay firm. She needing to be alone to think. Cake decided to go to the party by herself, Fionna knew she was crushing on Lord Monochromicorn.

The events of last night still circled Fionna's mind. She found herself still laying in bed, with her hand between her legs. She experimented with sliding a finger inside herself. It felt strange, but good, to have something there.

Since Cake was gone and BMO was at the party, she was all alone. She moaned, picturing Marshall pumping his slender fingers into her. She was so lost in her pleasure that she didn't see Marshall materialize next to her bed.

He smiled at her, while there was definitely lust in his heart, there was something else for the blonde girl in bunny ears, too. He wasn't sure what yet. He hovered over her as her blue eyes opened in shock.

"Marshall!" She moved to remove her hand from her panties, but Marshall stopped her.

"Fionna, don't stop. Unless you want me to help." He grinned wickedly as he slid her panties down revealing her sweet, moist pussy to him. "Spread your legs", he whispered, as he positioned his head between her thighs,"relax". Marshall's tongue was quite skilled, being demon-like he did things to Fionna that she never thought was possible. He licked from her clit to her entrance, teasing her by going in a bit. Fionna rocked her hips, pushing herself onto his tongue. Suddenly, Marshall was nose deep in her sweet pussy. He wiggled his tongue, teasing every inch of her slick insides. Her orgasim came fast, and she cried out as Marshall's mouth was filled with her juices. He licked her clean as Fionna saw stars.

"So good". Marshall said as he licked up the rest of her fluids.

Fionna's heart was pounding, but her body was so relaxed. She down at Marshall with sleepy eyes. His soft raven hair glistened with sweat, and smiled dangerously still positioned between her legs. She blushed, trying to close her legs but kept them open with his pale hands. She turned her head, her face reddening more. She couldn't believe this was happening. Just last week there was nothing more than the constant teasing. But now it felt as though a fog had entered her head, and it prevented her from thinking with her brain, only her heart and loins.

Marshall couldn't believe that the blonde girl of his dreams lay before him so vulnerable. He could still taste her sweetness on his lips. The blush on her pale cheeks was adorable, and he floated up over her, taking her cheek and gently nudging it toward him. His eyes met her shy blue eyes, and she quickly tried to turn her head again. "You're so beautiful". He whispered, while running his thumb over her lips.

Fionna gazed out the window. It was getting dark out, the sun was just fading out. She knew that Cake and BMO would likely return soon. But her heart had became heavy. She looked at Marshall, her eyes sad. Her lips began to quiver. "What are we, Marshall?"

Marshall smiled, while running his hands down her chest. "We're good friends."

Fionna felt her heart drop to the floor. It was like her body had turned to ice, and tears she could not contain began to assualt her cheeks. She lay before Marshall, the one who claimed her innocence, completely naked and vulnerable. "Get out, Marshall."

Marshall's eyes widened, and he dropped to his feet. He walked reached out for her, but Fionna slapped away his hand. "Wait, Fionna, what's wrong?"

Fionna lept from the bed, grabbing a sheet to somewhat cover herself. "Glob, Marshall! How could you play me like this!?" She cried.

Marshall reached out for her, trying to envelope the girl in an embrace, but she tried to shrug him off. "Fionna." He murmured, trying to hold her, but she over powered him. She began to run, and then tripped over the sheet she used to shield herself. She fell, her head connecting with a dresser. Marshall, stunned, rushed to her, picking her off the ground. A trickle of blood ran down her forehead. The girl appeared to be dazed. "Fionna!" He cried.

Fionna and Marshall were so absorbed in Fionna's injury that they didn't see Cake and BMO enter the room, nor did they hear her calls. Cake stood there, her hair raised, fangs showing.

"How dare you, Marshall." She spat. "Get away from Fi! Why in glob is she bleeding?"

Marshall looked from Fionna to a enraged Cake, to a shocked BMO. His dream had turned into a nightmare. He stood up, offering his hands in the air as a sign of peace. But Cake lunged at him, throwing him against the wall. Anger filled his veins like blood, and he felt himself turning into his demon form. Cake stretched her arms out to pummel him against the wall once more. He contemplated tossing the little kitty like a rag doll across the room, but the look in his beautiful Fionna's wide eyes made him pause. "You have no idea who you're messing with, kitten." Was all he said as he vanished into the night.
