Chapter 1

Finn sat on Marceline's couch, his expression showing much discomfort. He punched the cushion a few times, then realizing that the seat wouldn't become any softer, he pouted and crossed his arms over his chest.

"Chill out, Finn." The Vampire Queen insisted.

"Honestly, Marcy, this couch is horrible. I'd rather sit on needles."

"I could make that happen for ya." She twisted her lips into a sinister smile, and then began to chuckle.

Finn pulled his bottom lip in with his teeth and stared at the floor. "This sucks," he muttered.

Marceline rolled her eyes and went to join him on the couch, but instead of sitting on it, she hovered just a few inches above the cushion. She floated there for a moment, yawned, and went to retrieve her axe-bass from where it was sitting in the corner of the room. She occupied her spot again and began to pluck the bass with fluid, bony fingers.

Finn looked at her as she played, his eyes growing wider when the realization struck him. He thought she looked…beautiful.

He shook his head as if to banish the thought from his mind. She's my best friend. This is too weird. Still, as he gazed at her, the uncontrollable feeling of warmth and butterflies emerged inside him. He had never felt this way about anyone before, let alone his vampire friend.

"M-Marceline?" The human stuttered.

"What's up, Finn?" she asked, not bothering to stop playing her bass.

"Do you, you know, like anybody? Like-like, I mean."

Marceline's fingers froze suddenly and the room grew silent. She sat in deep thought for a moment, then met Finn's gaze. "I don't know. Why do you ask?"

"I-I was just wondering. You never really mention that kind of stuff, so I wanted to ask." Finn's cheeks grew pink.

Marceline raised an eyebrow. "Okay then," she said. She noticed that her friend was still blushing and snickered. Then she leaned in and pressed her lips to his cheek. The pinkness in his cheeks grew to a bright red, which made Marceline laugh even harder.

Out of nowhere her laughter faded and was replaced with a serious expression.

"You okay?" Finn asked.

"Yeah. It's just, when you mentioned the whole relationship thing it reminded me of something my dad said a few days ago."

"Oh? What did he say?" Curiosity danced across every word.

Marceline pursed her lips and locked her gaze on Finn's. "Well, you know how I'm the queen and all?" Without giving Finn the chance to answer, she continued, "Well my dad is all concerned about me ruling the Nightosphere and junk. He said that since I'm a thousand years old, it's time for me to grow up and take responsibility. It's inevitable. So I need a king, and I'm not allowed to kill this one," she scoffed.

Finn sat there, unblinking, his eyes fixed on the wall straight ahead. He tapped his fingers nervously on the cushion.

"So…yeah." Marceline broke the silence.

Finn remained in his lifeless trance.

"Hey, earth to Finn!"

"What? Oh. Sorry, Marceline. I'm just in shock."

She sighed and floated down to take a seat next to her friend. "It's not like I'll find a king, anyway. There's no one who likes me, at least not like that."

Finn drew in his breath as he noticed Marceline's eyes fill with tears. He suddenly felt helpless and full of remorse. It was on rare occasion that she ever cried, so seeing her do so took him aback.

"Don't worry, Marcy," Finn began. We'll find you a boyfriend. There are plenty of people who love you. I promise."

Chapter 2

Marceline sat on the couch, her arms wrapped around her legs as her chin rested on her knees. Tears streamed down her pale cheeks. She would sniffle now and again and occasionally brush the tears off of her face with the back of her hand. Finn sat on the other end of the couch,, sadness plastered all over his face.

He sighed deeply and slid closer to her. Please don't kill me, he thought. Carefully, Finn wrapped his arms around Marceline's body and pulled her closer to him. To his amazement, she didn't pull away or make a fuss like he expected. She snuggled herself into his body, her hands tightly gripping his t-shirt.

"I-I love you, Marceline. It's going to be okay," he whispered as he ran his fingers through her raven black hair. Finn's heartbeat increased as soon as he realized what he had just said. He loved her? His breathing became shallow and the room began to grow hotter. Beads of sweat formed on the boy's forehead.

"I love you too, Finn." She said it with no hesitation.

A slight smile spread across his lips as he heard the vampire say those words. Without being able to control himself, he pulled her even closer to him. He pursed his lips as the overwhelming urge to kiss her came over him. Should I?

Before he could take another breath, Marceline's lips were crushed against his. His eyes were wide with surprise for a few seconds, then they slowly closed as he began to kiss her back. She wrapped her arms around his neck, and he soon mimicked her actions by wrapping his arms around her waist.

Finn lost all sense of consciousness, his mind drowned in a deep sea of excitement and happiness. He opened his mouth and molded his lips around hers. Marceline pulled away suddenly.

"I'm sorry," Finn said. "Did I do something wrong?"

"No. I just don't know if we should kiss like that. I kind of have sharp fangs and all. The last thing I want is to accidentally turn you into a vampire because I kissed you too hard."

Finn gave her a half-smile and pressed his forehead against hers. "You're not going to do that. We'll be careful; don't worry about it." He brushed her cheek gently with his hand. "Just kiss me," he breathed.

She leaned in slowly, and soon their lips were playing across each other's again. Marceline climbed on top of him, pressing her body hard against his, kissing him passionately. After a few minutes they stopped and stared at each other, breathing hard, their bodies entangled.

Marceline slid off of him and cupped her hands over her face. "This is wrong," she began. "You're too young for a relationship. Besides, I'm no good for you, Finn. I'm no good for anyone. All I'll do is hurt you."

"You're amazing, Marcy. We have so much in common. You always find a way to make me laugh. You're pretty and sweet and just…awesome. Tell me how any of that is wrong." Finn wrapped his arm around her shoulders.

"I'm just no good. You could find someone so much better. What about Bonnibel? I know you have a thing for her."

Finn shrugged his shoulders. "I did, until I realized that you're the one I love more. Yo, you're like, my best friend. We're already so tight as it is. And we seem to have the same feelings for each other. Honestly, I don't see anything wrong. I think that this is great."

Marceline gave him a smile and kissed his forehead. "Yeah, I guess it is."

They sat in silence for a moment. She leaned closer to Finn and tilted her head to put her mouth inches from his neck, then paused. The bittersweet scent of human blood filled her nostrils and caused the vampire's bloodlust to flare up. She filled her lungs with a deep breath of air, then shut her eyes tightly in concentration. Her lips parted slightly, and Marceline closed them gently on his neck, held them there for a few seconds, and then kissed his neck again, this time in a different spot.

Goosebumps lined Finn's arms, partly because the feeling of the girl he loved kissing his neck was so incredible, and party because of the nervousness that aroused in him as he felt her cold fangs touch his skin.

"I just wanted to see if I could do it without killing you," she said as she pulled away. "But now that I know I can…" And she pressed her lips to his neck once again, but this time she held nothing back. Finn sighed blissfully and grasped Marceline's hand as he felt her tongue brush his skin, her cool lips dancing across every inch of his neck.

When she finally stopped she gave a small giggle and rested her head on his shoulder. She yawned and whispered, "I really do like you, Finn-a lot."

"I really do like you too, Marceline—a lot."

Chapter 3

Finn's eyes grew wide as he poked his head up through the hole in the floor, his hands gripping the ladder tightly. Marceline stripped her shirt off and slid her jeans down to her ankles, then kicked them into the corner of her room. This is so pervy, he thought. Though his conscience told him to do otherwise, he couldn't look away.

"Don't think I don't know that you're watching me, Finn," Marceline snickered. Finn blushed and climbed back down the ladder. He sat on the couch, embarrassed, and crossed his hands over his lap.

Marcy floated down to the living room. She had changed into her pajamas, which consisted of a tank top and a pair of sweatpants. "Did you like what you saw, lover boy?"

"I-I, well…"

"Ha! Don't worry about it. You're a teenage boy. I expect nothing less." She gave him a peck on the cheek. "So what do you want to do?"

"I don't know. I know that I have to get home soon before Jake flips."

"Yeah, you've got a point. Hmm…well you can stay for another hour or so," she insisted. "We'll watch TV."

"Sure," he said. Finn reached over to hold her hand. Marceline flipped on the television using the remote, but didn't pay any attention to the screen. Instead, she tilted her head back and fixed her eyes on the ceiling, her mind wondering.

"You okay?" he asked.

"Yeah, I was just thinking about how badly I want you to kiss me."

Finn smiled and tucked a few strands of hair behind her ear, then began to kiss her. It started slow, then became more passionate, and before he knew what was going on Marceline was straddling him. He slid his hands underneath her shirt and pressed down on her bare back, bringing her body closer to his. Finn's face was surrounded in a curtain of black hair as the vampire kissed him.

Still on top of him, Marceline pulled away to press her forehead against his. "We'd better calm down before we get too carried away," she sighed. "I'm wearing sweat pants, so I can feel a lot more than when I'm wearing jeans."

Finn blushed when he realized what she was talking about. "Sorry…"

She laughed and pressed herself hard against him. Finn sighed and she laughed again. "Yeah, that's why."

She floated up into the air and sat down on the edge of the couch. Finn sat up, and she slid closer to him. Marceline relaxed herself against the boy's body and he wrapped his arms tenderly around her, then leaned in to peck the area of her neck where she had been bitten.

"We'll be able to lose control with each other someday, but not yet," she said.

"Good. I don't think I'm ready yet," Finn admitted.

Marcy smiled and peeled the hat off Finn's head in order to play with his crazy blonde hair.

Chapter 4

Finn glanced at the clock. "Oh my Glob! I've got to head home." They had been watching TV for an hour and a half, their minds lost in the contents of the show.

"Alright," Marceline said.

He slid off the rock she called a couch and grabbed his pack from where it sat on the floor. As Finn opened the door to leave, Marceline called after him.

"What's up?" he asked.

"There's something I should probably tell you."

"Oh…kay," he responded, nervousness protruding in his voice.

"Well, the whole thing I told you about what my dad said about the fact that I need a king…yeah, that was kind of a lie."

"What?" Finn's heart sank, and his cheeks grew flushed with anger.

"Yeah…I guess I never should have pranked you so perfectly…again."

"M-Marceline! Why did you…gah! You lied about such a serious thing!"

Her devilish smile sank into a frown when she noticed how angry he was. "I know. I just wanted to see if you liked me, but I know you do now. And you know I like you now. So, what's the harm that came from it?"

Finn crossed his arms over his chest and released a long breath of air. "You still shouldn't have lied. How can I trust you with anything?"

Marceline hovered over and hung her arm over Finn's shoulder. "It was a lie told for a good purpose. You think we would have gotten together as boyfriend and girlfriend if I hadn't pulled that prank? You can trust me because you love me, and because I never lied to hurt you. We're together now. You should thank me."

"I guess," Finn muttered, his disappointed expression unchanged. "Am I really your boyfriend?"

"Duh," she said, a smile spreading across her face.

Finn gave her a half-smile and kissed her cheek. "Alright, no harm, no foul."

"So we're good?"

"Yeah, we're good." He brushed his lips against hers and headed out the door.

"I'll see you tomorrow, Finn," Marceline said with a wink.

"I'll be over first thing in the morning." And with that, Finn left the cave and made his way back to the tree fort, his eyes gazing up at the stars the entire way home.
