Thank you for choosing to read my trash! Please review at the end to give me pointers and motivation. Trust me, it helps a lot. If you're reading my other adventure time story, hang tight. Chapter three should be up in a few days! Whoop, whoop!

So, in the fic, Marceline doesn't really have to worry about breathing. Because she a immortal being, basically. Plus, if you get bit by a vampire, you won't be turned unless the vampire intentionally wanted to turn you into a vampire. But that's just my theory, dudes. Please enjoy!

DISCLAIMER: I don't own shiz.

P.S. May be self-harm triggering.

It had been eight hours since they had fallen into this pit that caved into itself, only allowing a small space for the vampire and the human. It had been okay so far. Knowing quite well the Jake was getting help and they would just sit tight until then. However, it was taking a lot longer then expected. Finn began to feeling a little restless, like a animal locked in a cage. Marceline had been helpful, entertaining him with stories and songs. But, that was before they realized the bigger issue. Although, there were ways for air to seep through the rocks, the oxygen wasn't coming in fast enough. This made breathing in not as satisfying as usual. The intakes of air seemed to strangle the boy's lungs.

"It'll be alright, Finn. Just try to get some rest."

Marceline had already forbade him from speaking a single word, so Finn just nodded in agreement. He tried to not think about the thin air, but whenever he didn't pay attention to his breathing he would begin a coughing fit. Ending those fits usually took half an hour, leaving his chest aching. Right now, he was resting his head on a rock, trying not to doze off. His body was completely exhausted, but he knew that if he fell asleep he may end up never waking up. This terrified him more than anything.

"Marceline?" Finn rasped out.

The vampire glares at him. "What the heck, Finn! I told you not to talk!" She yelled.

"Sorry..." The human whispered. A moment passed when Marceline finally sighed.

"What is it?"

Finn breath hitched, making Marceline think he was going to start coughing again.

"Do…do you think we're goners? I mean…it's been awhile. And I don't know how long-"

Marceline held her hand up in a gesture for him to stop.

"We'll be ok. I'm sure Jakes got it covered. Now if you'd just be quiet and save your breath we would-"

The vampire was interrupted with a loud growl. It took a moment for her to realize it came from her own stomach. All went silent as they made eye contact. Finn gave a worried look.

"I d-don't think there's…a-anything red in m-my backpack." Finn whispered nervously.

Marceline chuckled. "Don't worry, you weenie! Jake's gonna get us out WAY before I start going bonkers."

She turned to look at the boy, crouching with his legs to his chest. He nods in reluctant agreement knowing that if he spoke anymore, there would either be another coughing session or the vampire would yell at him. Finn still was very doubtful for the well-being of his friend. She seemed to be very insincere about what she had said and it wasn't settling the boy's nerves to the least.

"How about I sing something?" She asked, suddenly. Finn nods as a reply.

"I heard on a vinyl years ago. I haven't heard this one in awhile, but because of certain…events…I was reminded of how much I loved this song." Marceline said excitedly. "It goes something like this…"

Somebody get me a hammer

Wanna break all the clocks and the mirrors

And go back to a time that was different

A time when I

Didn't feel like there was something missing

Now my body and mind are so distant

Don't know how to escape from this prison

How can I

Free my mind?

Cause I can't breathe

I can't breathe

I can't breathe

I can't breathe

I can't breathe

How can I live in the moment

When my thoughts never feel like my own and

Don't know how to admit that I'm broken

How can I

Be alright?

Cause I can't breathe

I can't breathe

I can't breathe

I can't breathe

"That was nice." Finn whispers.

Almost an hour goes by and neither one has spoken. Finn had dozed off, against all his struggling he had lost the fight. Only half conscious of everything that was going on. There had been no sign of their rescue, and this had made Marceline fall silent and sullen. She tried distracting herself from the growing hunger she felt by listening intently to the rasp breathing of the human boy. She noticed that his air intake seemed to grow heavier once the boy and fallen into his restless sleep. However, this just made more problems, because his resting body sucked in the oxygen greedily, and much too fast. Marceline began to wonder how long Finn would had left before his lack of air started to really affect him. She thought it wouldn't be too long before then. The vampires head seemed to grow heavy as she sat there, contemplating. The hunger she felt was becoming much harder to ignore. Her keen senses came alive and her nose had already hounded out it's target. The fresh blood that was hers for the taking, not three feet away. She fought with her instincts for as long as she could, but it was beginning to be too much for her. After about half an hour of paying attention to only the breathing of the hero and the smell of his delicious blood, a change happened in Finn intake. In fact, he stopped taking in air completely. This jerked Marceline out of her daze, as she kicked Finn as hard as she could. The boy arched his back in response, taking in a sharp breath of air. He was only able to get half a breath before he began hacking violently. Marceline took action and grabbed Finn around the chest, pulling him into her lap. Tightening her grip around his chest caused him to take even breaths. But the hero appeared to be in a panicked state, not fully aware of the situation.

"Just breathe." She whispered over and over into his ear.

This soothed the boy and his hyperventilating with down, replaced with odd sounding breaths with an occasional hiccup.

Marceline didn't move from from her place even as the breathing softened. She was now very much aware of how close she was to Finn tender neck. It hadn't helped that the teen had let his head fall limply to the side in complete exhaustion, making it look like he was practically begging her to sink her fangs into his flawless skin. She could see the red hot blood pounding in his veins as she slowly slipped off his hat. Long, blonde hair draped over his shoulders, which was quickly tossed to the side so the vampire could see her target once again. She then began to pull the shirt down the humans broad shoulders, but when it didn't go far enough to stay there, she began to rip it off. Now she could clearly see the nape and notch of Finn's neck. The sight aroused her instincts, and she licked the hero's shoulder, up to the beginning of his jawline. Finn groaned in irritation, annoyed by the fact he that was exhausted and someone was waking him up. He began to move, but that someone had a death grip on his abdomen. A hand began to trace his chin, as a familiar voice whispers seductively into his ear.

"Shh, everything's alright, Finn. I'm just gonna take a little bite." Finn shivered in fear and anticipation.

He knew it was Marceline, he knew she was hungry for blood, and he knew there was no way out of this. She was already too far gone and there was nothing that would stop her from getting her fill of his blood. He whimpered as the vampire began to lick around his neck again.

"M-Marceline?" He stuttered out.

The vampire trailed her tongue behind his ear.

"Yessss,Ffffinn?" She asked.

Finn held back a moan as she whispered. "Just don't kill me…okay?"

Marceline began to hover over Finn's skin with the tips of her fangs slightly touching him.

"I wouldn't dream of hurting you, Finn. And I'm sorry I have to do thisss."

She stopped moving as she found the perfect sweet spot to take her first bite.

"I'll only take a little bit, alright?" Finn nodded ever so softly, closing his eyes tight.

Instantly, Finn could feel the two sharp fangs sink into his tender spot on his neck like two tiny swords. His first response before he even felt the pain was to scream. However, while one of the vampires hands were occupied with keeping the teens body in place, the other had suddenly grabbed onto the boy's jaw. Her hand was completely covering his mouth, making it difficult for the boy to keep his breathing steady.

However, breathing wasn't Finn's first priority at the moment. As soon as the pain from getting his blood sucked right out of his body kicked in, he began to sink into it. The pain intoxicating his entire being.

And what confused Finn the most was that he was loving it.

He craved the sensation of feeling nothing but the pain Marceline was performing. His whole body went numb as he focused on that one thing. All his worries of getting out of that hell of a pit simply vanished from his mind.

The throbbing perception was his center, there was nothing else he felt. He shivered in anticipation, his eyes rolled to the back of his and moaned.

He began to feel lightheaded as he became partially aware of how much blood he must have been losing. But the sensation of pain was much more attractive to him than the thought of unconsciousness. The thought caused him to lean into the source of the pain, wanting more.

Instead of taking his approval, Marceline pulled out of the boy's neck. She had had enough to regain her control, and was now looking at the appalled boy in front her. His hair laid in every awkward direction, as sweat dripped from it. He was barely taking any air in as he breathed heavily. He looked dead tired but his dilated eyes glazed over with excitement.

"W-why'd you stop?" He rasped out, barely audible.

Marceline began to lift the boy off of her lap.

"Oh F-Finn…" tears began to weld up in her eyes as see stared at the hysterical eyes of the human teen. He looked like a complete wreck.

Every part of his body started to shake, as Marceline realized that he was going into shock. The vampire began to panic. She pulled the boy into a sitting position and rubbed circles on his back. This only seemed to erratic his breathing even more. Finn groaned in exasperation from being moved off the comforting, but soon began to appreciate it. For the moving of his body woke the sensitive nerves up in his body, cause an aching sensation to once again distract him from the fact that he couldn't get enough oxygen.

"oh Glob, Finn, I'm so sorry." Marceline fails to hold back a sob.

"I p-promised-and I couldn't…control myself!"

Finn blinks a few times, attempting to focus his eyes on the vampire. However, he felt so lightheaded and extremely exhausted suddenly. All his adrenaline he had worked up had left him. Now he sat there, his head barely able to stay up, his breathing so tight he didn't even feel like he was taking in air anymore. He wanted to speak, to tell Marceline that it was alright. But whenever he opened his mouth to talk he would only end open gasping dramatically, his aching lungs sucking in hungrily. And this only made the vampire queen feel worse. Finn finally decided that the best thing to do at that moment was to sleep, because he was freaking worn out. The human no longer feared the thought of never waking up again, because he would be just as happy if he slept till he died, his exhaustion was just too much. He began to focus on the soreness in his chest, enjoying the pain he felt. His body slid off the edge of the rock, now lying down more than sitting. Marceline noticed this and shot up to adjust him in a less awkward position. Yet, she hesitated before touching the boy. Visions of seeing a bloody corpse in place of Finn's sleeping body flashed through her mind. She quickly retracted her extended hand and floated back slowly. She stared at the sleeping boy for a long while, her eyes bloodshot. Everything continued as it had before the vampire had went crazy, except for now Marceline noticed Finn breathing was more labored, if that could even be possible. Marceline felt a sense of panic to get the teen out of this suffocating hole. She began faze through the rocks around them, as she had tried earlier. But, same as before, Marceline couldn't figure out which way was up or down. "This pit is much deeper than I would have guessed." She thought to herself nervously. She continued her search hopelessly. She knew that it was a waste of time to faze around in the rubble, trying to find the exit yet not straying too far from the hole. The reason she continued her fruitless efforts was in no way clarified. All she wanted was to put distance between herself and the boy. She needed to clear her mind from the whole situation. But questions just continued to race in her brain.

"How could I have done that? Why didn't I have more control? How am I gonna get Finn out of this mess?!" Marceline screamed in frustration.

No matter how hard she tried to have faith that Jake would get help, ten hours was long enough for her to realize that there was no time left. Finn was on the verge of dying! And it was all her fault. She thought about how many ways she could have prevented herself from hurting Finn.

"And now I just left him there in that hell pit, because I couldn't face him!?" Marceline thoughts filled with self-hate as she fazed back into their hot, musty hole.

When she entered in, tears falling down her cheeks, she was met a terrifying scene. Instead of the tragic, yet peaceful site of the boy sleeping. She was met with Finn sitting straight up, his eyes wide with horror. His mouth was opened and gasps were coming out, occasionally gurgling as if he was drowning. His body shook tremendously with tremors. Marceline stayed where was, completely in post trauma. Instead of seeing a boy in desperate need of air, she say and blood sucked corpse, shaking wildly on the floor and making animalistic noises.

"No! I didn't mean t-STAY AWAY FROM ME!" She screamed out, fazing once again through the rocks. She was too horrified to notice the loud drilling sound that seemed to be coming closer.

Finn woke up with a start, not knowing exactly why until his natural reaction began to reach out for air. However, there was none. Finn gasped in response. "There's-There's no air left!" He thought frantically. "Ohmyglobohmyglob!" He felt as though he was drowning. It reminded him of his ancient fear of the ocean, and for a moment, the fear came back. His arms ripped through the void, as if trying to grab a hold of the oxygen his burning lungs desperately wanted. Everything felt nauseatingly close. The rocks all around began to slowly sink in, towards the hyperventilating teen. Finn imagined water crashing through stones and absorbing him. His head felt so light that he began to believe he was actually floating in water. Black spot blocked his vision, but suddenly he could see Marceline standing in the ocean, staring at him with an eerie look of contempt. Finn wanted so badly to call out to her, to beg her to save him from the terrible water abyss.

"I don't wanna die!" He thought hysterically. "Marceline help!"

But Marceline didn't look at finn with a sense of urgency to help him, it was more of a urgency to leave. Her face showed nothing but disgust, and it devastated the dying human boy. Hot tears began to run down his face. The crying caused mucus to fill in his throat, causing him to gurgle and actually begin to drown. He had no energy to move. His chest hurt so bad it was all he let his mind think about. He forgot about the fact that he was suffocating, the fact that Marceline had abandoned him, and the fact that he was literally dying. All he knew was pain, because pain was the only certainty in his life. If he cut himself, there was pain. If he got beat up by a dragon, pain was there. If he slipped and fell on the bathtub, pain got to him first.

And somehow knowing that it was the only thing that wouldn't, or even couldn't abandon him, just made him crave it deeply. As he laid on the cold hard rocks, there's was no one else. At his last attempt to breath, there was the pain. As he lost consciousness, pain was the last thing he felt. And he loved it.

"Hurry, PB! I can smell them, I can smell them!" Jake shouted.

He smiled excitedly. His buddy was still was still alive down there. His sense of smell reached the uncanny scent of the teenage boy. He could smell his sweat and his hot blood. A happy sign that his heart was still ticking. As Bonnibel dug deeper with her super drill the dog shouted with joy

"oh boy, I can hear him!" His ears taking in the comforting sound of the rapid, yet soft heartbeat. Jake just assumed the boy was a bit farther away, that's why the beat was so quiet. "

Do you hear Marceline?" Bonnie asked in concern. "I don't think so!" Jake responded. "Maybe they got separated or something." PB sighed nervously. "Maybe." The dog turned to face the pit again and continued listening to the heartbeat of his little brother. A few minutes of listening intently went by when something changed in the pulse. It began to grow abnormally fast. "Princess! Somethings wrong with Finn!" Jake shouted urgently.

"What?! What's wrong with him?" PB asked sharply

"He heartbeat is CRAZY fast all of a sudden! I think he might b-" The canine stopped short, his ears going up and his eyes filled with horror. "What's happened,Jake." Bubblegum asked, almost screaming. Jake stared at the princess in desperation. "The heartbeat! I-it just stopped! Id can't hear it anymore! WE GOTTA HURRY!"

PB quickly changed gears on the drill and sped up. Her thoughts went wild. She wasn't gonna let Finn die in a filthy pit.

There was a sudden jolt from the drill as it hit an empty space. The rocks around all fell down from the trauma. Luckily, none falling on the body that lay on the dirty floor.

Jake stretched to the boy, turning him around so he could see the face. It was Finn. But it was almost unrecognizable. Besides the fact that the teen was now caked in dirt, cold sweat, and blood. His face was far too pale. His eyes half opened and almost falling to the back of his head. Jake grew a couple feet and took the into his arms. Finn's neck leaned off the dogs arm, his mouth opening from gravity's force. Revealing obvious teeth marks on the human's neck. Jake tried to hold back his anger at seeing this for he had quickly realized the boy wasn't breathing. "H-hey bud, it's time to wake up!" Jake said, shaking him soundly. When he got no response, the dog began to shake the body intensely. "Wake up, dammit!" He screamed, tears falling onto the dead body. Bonnie quickly snatched the boy away from Jake. "Stop it!" She yelled, gently setting the boy down. "There still may be some time!" She began to push on the boy's chest, harder and harder each time. Counting a certain amount, and then putting her lips to his mouth and blowing in. She continued doing it periodically, getting more frantic each time. Soon she yelled in painful frustration. "ITS NOT WORKING!" She screamed. But suddenly her eyes shot up in realization. She quickly ran to the machine grabbed a bunch of loose wire and clipped them. She ran back to Finn's body, pulling the wires along side her. "I'm sorry for this, Finn." She said sorrowfully. Then almost instantly, pulled the raw end of wire straight into Finn's chest. Developing a electric current that coursed through his body. The was suddenly the sound of something greedily taking in air, and then a bloodcurdling scream. His back arched as his body still reacted to the excruciating pain of the shock. He tried to breathe in some more air, but his lungs refused to take it in.

PB and Jake both sighed in relief at seeing their friend still alive. However, they soon realize something was terribly wrong when Finn began to gasp and gape like a fish out of water. "He can't breathe!" Bubblegum yelled. "Give me the knock mask, Jake!" The dog quickly handed the princess something and she raced to put it over Finn mouth. The boy, barely aware, began a panicked fight with the mask. However, Jake wrapped his arms around the boy, ending his measly attempts. It took a moment for the anesthesia to take effect, since the boy was taking very small breaths. But soon, he was out cold, breathing raggedly yet much better than before.

"He must be in so much pain." Princess Bubblegum says sadly.

"Yeah, especially since there's…oh I don't know-LUMPY BITE MARKS ON HIS NECK!" Jake yells, completely furious. "Where is that dumb-dumb vampire anyways?" He asks. PB shakes her head. "I don't know." She wants to stay and look for Marceline but she knows that there's someone who needs her more, at the moment. "But, we need to get Finn to the kingdom hospital, stat."

When Finn finally wakes up a few days later, he is overwhelmingly greeted by his most closest friend. Pain.
