AUTHOR'S NOTE – Hello everybody! Another chapter for First Encounter here :D. Please if you're new to the story and made it this far, do hit that Favorite, Follow, Review button(s) to continually support this fanfiction. I'm liking it so far and with enough support I'm going to keep writing, maybe a series of encounters? Anyway have fun reading this, in which I don't own adventure time characters, plots or itself.

"Will you quit it? I'm just trying to feed you!" Marceline shouted from inside the cell. Finn resisted with all his might and shook his head at whatever was trying to be forced into his mouth. It reeked of decaying flesh, rotten meat that didn't smell like it was from an animal, and most of all old blood. Finn kept on squirming and resisting the spoon full of disgustingness, until a hand came over the top of his head. "Hold still!" Marceline shouted shoving the spoon in his mouth. Quickly, she put a hand over the hole in his neck and the other hand over his mouth so he couldn't spit out. The taste was awful, not cooked and nothing to make it better. Finn tried to spit it out but was blocked by a hand. So he held it in his mouth, letting his taste buds suffer under a bloody piece of rotten meat. "Swallow the damn food Finn." Marceline ordered. Finn glared at her and still held the food in his mouth, trying his best not to give into his own hunger. "I can hear that stomach roar from a mile away, swallow it." Marceline said. Finn closed his eyes and gave the thought of eating something so disgusting a chance to cure him of his hunger, and swallowed the meat.

It quivered down his throat, clashing onto the walls of his inner throat and down to his stomach, making his bones shiver and goosebumps form behind his neck. He shook off the feeling of eating it and Marceline smiled and let go of his neck and his mouth. "That's better, now we're going to finish the bowl." She stated. Finn sighed and watched her scoop another piece of the meat from the bowl. The spoon made its way to Finn's mouth and he opened, knowing that he couldn't fight to not eat the food. "There you go, is that so hard?" Marceline asked. Finn glared at her some more, moving her hand over to his neck hole so the food wouldn't fall out. He let the piece of meat fall down his throat and swallowed, letting the feeling of grossness pass over him. "W-why won't you l-let me go?" Finn asked managing to get the words out. Marceline scooped another piece of the meat and sighed, not getting the spoon to Finn's mouth. "It's complicated." Marceline explained. Finn frowned and saw the spoon on it's way. He opened his mouth and quickly ingested the piece of meat. "What do you m-mean it's complicated?" He asked. Marceline again let out a small sigh and took the spoon out of Finn's mouth, and kept her hand on his neck. "You wouldn't understand." Marceline replied. Finn blinked at the vampire and let out a small sure smile. "I would." Finn said through his shackles. She smiled back and removed her hand from his neck, backing up against the wall.

"You see, my father is the overlord of the Nightosphere. It's always been whatever he says goes. And years ago when I was turned into a vampire, I showed great potential for possessing his gift. But there was a problem. He believes that I will rebel against him and he forced me to prove my worth. So why not in the worst way possible destroy the very thing that will stop him from unleashing his army." Marceline explained.

Finn widened his eyes and looked to his shackles and started to pull on it as hard as he could. Within every desperation, he wanted to be free, but was stopped by a hand on his cheek. "Don't you see, this is why you're here. So you can be locked away. So my father doesn't eradicate me from existence. You're the very thing keeping me alive." Marceline further explained. Finn looked at her and shook his head. "Don't you see a fault? B-by killing me you saved yourself but potentially killed hundreds maybe thousands more." Finn fired back. Marceline glared at Finn and threw the bowl of meat down on the floor, creating a shatter through the cell. "You don't understand human! He'll kill me if I don't let you stay here!" Marceline shouted. Finn glared back and reached forward with the shackles. "You don't understand you vampire! He wanted me to kill you!" Finn shouted. "No he wanted me to kill you!" Marceline argued. The two stared at each other, breathing heavy and glares haunting the both of them. Without a sudden delay or thought, Marceline rushed forward, grabbing Finn by the throat. "You said that like if you care boy." Marceline stated with a smirk. Finn held his breath and leaned forward, glaring at the vampire. "And you care about him?" Finn asked through the hand clenched on his throat. The words rang through the vampire's head like a ringing bell and slowly her hand began to release from Finn's neck. "You don't know anything about me, nobody does." Marceline stated. Finn smirked and raised an eyebrow toward the vampire. "Marceline, from what you told me about your father, he's scum. You know he is but you want him to be around as that figure. So you cling to him and whatever he does, you do because you act as a follower." Finn explained. She stepped back from the shackled human and looked back toward the door, then back again toward Finn.

Marceline lunged forward and unleashed a punch to the right cheek making Finn embrace in pain, tasting a bit of blood in his mouth and hearing it drip down to the side. Without warning, the door clasped open, revealing a dark silhouette in the doorway. "Ah Marcy, looks like your treating your pet very nicely." Hudson said striding in. Marceline sighed and watched her father step close to Finn, making him smirk. "Not so tough now are you Mr. Finn." Hudson stated. Finn glared at the vampire overlord and looked into his eyes. Nothing but a reflection of himself appeared in the pupils of the dark man. Hudson laughed and turned back toward Marceline. "You know what you must do, he's worthless now. Dispose of the boy." He ordered. Marceline raised her eyebrows and looked at Finn. He looked at her and shook his head quickly, she gulped and walked to her father. "Father no. We need him alive in the Nightosphere." Marceline argued. Hudson Abandeer turned around narrowing his eyes at his daughter and turned his expression grim. A hand came across her face, making her head hit the nearest wall with little to no force. "No back talk Marcy. He's not here as your living sex doll. Or your trophy. He's here because he's our capture. Now that I have what I need, we don't need him anymore." Hudson explained to his now downed daughter. He began to walk toward the doorway and he stopped, glancing back toward Marceline on the ground. "I thought you were strong enough not to share a bond with this weakling." He stated with a stride out the door.

The door slammed shut leaving only candle light in the cell, and the sound of walls bashing with fists as Marceline went from wall to wall screaming. She ran up to Finn, grabbed his throat, and raised her fist. "He's right, we don't need you!" She shouted. Yet her fist never touched Finn's face as he clenched his cheeks and squeezed his eyes tightly shut, only to feel the soft cold lips touch his cheeks. "But I never said I don't need you." Marceline said, setting off constant kisses to Finn's cheeks then up to his lips. Finn moved into the kisses and tried moving his hands in the shackles. She released and looked at the shackles and at Finn. "We need to get you out of here." Marceline stated. Finn nodded and watched as Marceline reached up and pulled the chains, straining only for a second or two, and broke the chains in two. Finn didn't expect his legs to be as weak they were and he began to fall, only to be caught by Marceline. "I got you." She said. She knelt down and broke the bottom chains on his feet and feeling of freedom slowly began to fill the hero's heart. But not to the rest of his body functions, as he tried to move but shocks of pain were sent through his entire body. "Stop, stop!" Finn shouted as Marceline set him gently down on the ground, up against the wall. "Shit dude we got to move, my dad will want to see you dead in here." Marceline explained. Finn looked at Marceline and put a hand over her cheek. "I won't make it like this, there's got to be something we can do." Finn replied.

Marceline looked all over Finn's body to see a slow decay of muscle in his legs and bruising all over his chest, arms and face. Finn blinked and could feel a black out emending to his body. He blinked as fast he could, trying to keep himself awake, and trying also not to think about how weak he was. Then slowly a different thought came over his head and it seemed to also hit Marceline too. She looked down at Finn as he took a big breath in and turned his neck to the side, looking at Marceline for assurance. "Do it." Finn commanded. Marceline took a breath in herself and slowly knelt down, digging ever so slightly her fangs into the human's skin.

At first, it was painful but as Marceline began to fully bite down, the pain grew to an extent and slowly turned not to pain and suffering, but adrenaline. Blood began to drain from Finn's neck and into Marceline's mouth making her purr with delight, also making Finn close his eyes and feel the drain. She released and watched as Finn held the bite mark, same as the night they first met, watching the transformation slowly take hold. The wound resurfaced, making veins slowly form and travel down all over Finn's neck, through his chest. He blinked and coughed turning his head to other side to only feel skin was forming on his other side. "Oh my glob, Finn, you don't have a hole in your neck anymore." Marceline stated as she felt the smooth skin on Finn's now formed neck. She grabbed onto Finn's cheeks and looked into his eyes. Blue began to battle over a crimson red tint and with one small blink, his eyes were beat crimson red.

Marceline stood up and watched the now vampire endured Finn stand up and pop his neck. He smirked at Marceline and she nodded her head. "Well you turn out to make a good vampi-." Marceline started but was interrupted by a mash of lips. Finn pulled her close and put his mouth all over Marceline's making her swing her arms around the back of his head and moan. He released her and smiled, with not an intent of murder but lust. "By the way, I loved your tongue." Finn said. Marceline blushed at the new Finn, slowly letting go of him. "Later?" Marceline asked. He only nodded at the vampire's remark and he went towards the door. "We're going to need weapons, got any ideas?" Finn asked. Marceline approached him and pondered a bit before remembering the demonic sword that Finn had. "I know where your Demonic Sword is at the least." Marceline replied. Finn nodded and slowly opened the cell door, gripping on Marceline's hand, letting her follow close behind him, and out the doorway.
