Author Note: ((LEMON/SMUT IS IN THIS CHAPTER)) Sorry to those who may get offended, I did warn you. Sorry if It sucks, just in case anyone thinks that XD.

I have no idea why, but I was having such a bad amount of writers block and boredom, I believe it was caused by the cold I had, but I'm not entirely sure to be honest. Anyway I hope you all enjoy this chapter, So many things are happening, also I am gonna write the first chapter for another Adventure Time fan fic, which will release with this update, depending on you lovely reader's opinions of the new fanfic I will either keep it going or delete it. Anyway you're all not here for that *Laughs to myself* let's get down to business. You're all lovely readers!

Also I saw the most recent episodes of Adventure Time, Pre Boot and Re Boot, not gonna spoil anything, but this is where "Finn's Soul" Will definitely be an AU since the events in the episodes easily destroy my plans for the fanfic.

One more thing, if anyone has any fan art or anything they want to share then feel free to message me about it, I may start a forum soon as well for all you lovely readers, but I'm going to start making commissions to my good buddy on deviant that made the concept for the Soul Sword since I love the art and I suck at art myself haha. It might take a bit though since I am a poor little bastard Haha. Enjoy the story! *Waves goodbye before typing on a computer.*


Marceline was slashing undead in seconds as she pounced like a wild animal at each group with her ax base. Nearby explosions of fire were going off in the center of a massive horde of corpses as Phoebe burnt her enemies to ash, trying to break through the horde only for more corpses to rise up.

Phoebe growled in anger as her rage boiled, her physical body an uncontrollable mass of flames, mirroring her emotions. "These fucking undead are blocking me from helping Finn, how many people did the Lich kill over its existence to have an army of this size?" Phoebe's thoughts flew through her head rapidly as she continued fighting.

Marceline on the other hand was easily dealing with the returning undead. She was just about to finish off a skeletal giant until every single undead halted and began to turn to ash as the magic bounding them faded out of existence. Marceline just stood there mouth agape before she began to rush towards the Lich's lair. "Flame head hurry up! Something is up, I want to make sure Finn is alright!" Marceline then began to float, moving quicker through the air as she approached the collapsed lair calling out to Finn, she reached the hole, looking down into the hole in the earth to spot Finn looking up towards her and the sky. A smile crossing his face when he saw her.

Several hours had passed since then, Finn had taken the Lich's crown to the Candy Kingdom and was praised for finally bringing the Lich's terror to an end. Finn didn't seem to make it as big of a deal as it was to others, deep down he kept hearing the Lich's words repeating in his mind. "The Forsaken One… I've heard that tittle a lot." Finn thought to himself as he departed from the Candy Kingdom, his lover close behind him as Phoebe left to return to her kingdom for the day. Finn continued to walk until he felt a soft pain on his neck. "Vampire bite!" Marceline yelled as she pinched Finn's neck. "Now you must be forced to eat baby goblins forever!" Marceline spoke in a mischievous tone as she flew in front of Finn in a sitting position. "Oh really? Then I can fly and tickle you!" Finn jumped doing a flip through the air before landing flat on his stomach, causing Marceline to burst into laughter as she teased Finn. "Wow your still such a dork!" Finn only joined in with her laughing before getting up and walking again, the treehouse came into view after a few minutes, Finn was glad because storm clouds were forming overhead as thunder echoed loudly. Finn unlocked the door, letting Marceline fly inside as the door opened, he entered after she did and he closed the door behind them, taking off his pack and sword, placing near the door. Finn took a moment to look at the new form of Soul Sword, the red bolted metal plates on the blade having a shine to them as light from the room hit the metal, reminding Finn of the power of the weapon at its full potential. Finn literally disintegrated the Lich and erased him from the universe, permanently ending his life forever. He closed his eyes as lightning struck somewhere out in the grasslands, causing a loud crackling sound to explode through the air. Finn then opened his eyes as he heard the fast drops of rains. "At least it isn't a knife storm, I really am not in the mood for collecting a bunch of daggers in around the house today." Finn said in a joking manner as he followed Marceline upstairs, ignoring the pile of letters by the door, knowing very well what their contents were.

Finn was greeted by a smiling Marceline when he entered the living room. "Hey Finny." She said seductively. "Hey Marcy." Finn returned in a flirting manner as he wrapped his muscular arms around Marceline's waist and held her close to him as she wrapped her soft pale arms around the human's neck. Shortly after gazing into each other's eyes the two began to kiss, a hot passion burning as time seemed to slow around them. Before Finn knew it he was pushed onto the purple chair, Marceline mounting herself on top of Finn's lap as she pressed herself against him well giggling seductively. "M-Marcy are you teasing me again?" Finn stuttered as he frantically tried to assess the situation he was in. Sadly the only reply Finn got was Marceline's soft lips pressing against his, causing his mind to slowly go numb as he got sucked back into the passion.

Marceline placed her hands on Finn's shoulders grinding her butt against Finn's manhood as she slithered her tongue into Finn's mouth without resistance, letting her know he was fully absorbed into the passion. She could feel her body heating up. "I can't hold back anymore, I can't let all this stress get too us, Finn I love you and only you." She said this in her head as she gazed down at her man and floated off of him and pulling him by his arm up to the bedroom, leaving Finn with a numb feeling of passion as he followed her, his deepest instincts rising to the surface. "Marcy are you sure about this? I mean I have never done this before and I don't want to rush you or-" Finn was cut off by Marceline kissing him passionately again, his eyes closed as he lost the last shred of will power he had left to resist. "It will be alright Finn, I noticed how stressed you have been lately and I don't want it to affect you badly. I'm doing this for more than that though. I love you Finn and I want you and only you and I don't want to lose you… So will you reassure me and be my personal hero for the night?" She said the last sentence in a seductive manner which caused Finn's entire face to go red as thoughts flew through his mind. Ultimately Finn shook his head and cleared the thoughts away as he focused only on one thing, his lover.

Finn crawled on top of Marceline as she laid down on her back on his bed. He slowly caressed her body with his hands, bringing his hands around her bust as his heart rate increased. He then took his hands away as Marceline watched him pull his shirt off over his head, exposing his muscular body. She bit her lip as she stroked her fingertips down Finn's chest and abs. "Mmm… What a strapping man." She spoke seductively as she felt excitement fill her when Finn continued by removing the rest of his clothing. His excitement was obvious when Marceline saw his hard manhood, she could only guess it was seven and a half or eight inches long as she gazed at with lust in her eyes. "Wow Finn, you really packing huh?" Finn could only reply to Marceline by helping her remove her clothes, tossing them to the side of the room and leaving Marceline on the bed in the red laced underwear she had bought at the Candy Kingdom.

Finn leaned down and licked up the side of her neck, teasing her bite marks by nibbling on them, causing Marceline to shiver in pleasure as she stroked Finn's length. Finn then slid his hands down Marceline's figure, unhooking her bra and letting it fall of the bed as he went down on her and began to suck on her right breast well kneading her left breast with his hand, letting his right hand go down and rub her slit through the lace. Marceline let out a pleasured moan as she felt herself become wet, she was surprised by how skilled Finn was even though he was a virgin. Finn didn't give Marceline a break, he began to twirl his moist tongue around her nipple well he pulled Marceline's panties down and began to run his index and middle finger up and down her wet slit before he teased her clit. This action caused Marceline to let her whole voice out in pleasure as she felt her body shiver growing sensitive as her mind grew numb for any feeling besides pleasure and lust. Finn let a smirk cross his face as he lifted his head up from his lover's breasts well sliding his fingers into her, moving his fingers back and forth as his lover wrapped her fingers around his manhood and began to run her hand up and down its length with more force, causing Finn to let out a moan of his own.

Finn could feel his mind going blank as he felt Marceline stroke his manhood, he decided to step it up a notch. He slid his fingers slowly out of his lover before he went down between her legs, at first Marceline raised an eyebrow, but soon arched her back in pleasure as Finn began to slide his tongue against her slit before he slid his tongue around her clit, causing Finn's tongue to be covered in his lover's juices as her body twitched and let her climax with a loud moan.

Finn licked his lips as he grinded his manhood against Marceline's slit, causing her to bite her lip as she panted from pleasure. "Put it inside me Finn." Marceline commanded lustfully as Finn complied. He slide his member into her wet tight walls as he let out a joyed moan of pleasure, feeling pure bliss by being connected with the woman he loves for his first time. Finn didn't wait a moment though as he slammed his member all the way inside causing her moans to fill the room, Finn gripped his lover's hips with his pale hands as he let out a moan of his own as both their faces had a dark red blush.

Marceline felt as if a shock of electricity was going into her body as Finn's manhood spread her tight walls to fit. She couldn't resist climaxing on her own after only several minutes, covering Finn's member with her juices as she crossed her legs around Finn's hips to pull him deeper and keep him inside her as he began to pant heavily. She took enjoyment at looking at his face, his expression changing as he tried his best to pleasure Marceline without giving in. "You already made me climax plenty of times, so it's time we both have an orgasm together my hero." Marceline thought in pure affection and lust as she quickly caught Finn off guard and swapped positions with herself mounted on top of Finn, rocking her hips causing Finn to arch his back at the same time Marceline did causing them to both let out moans, not caring who could hear them. She began to bounce on Finn's length her legs shaking from the pleasure of climaxing over and over, their body liquids covering each other, filling the room even more with the scent of their act.

Marceline raised herself to the point the head of Finn's member was the only part inside her before she let herself go and slide down effortlessly as his length hit the deepest parts, causing her to climax hard well tightening her walls around his length. "Oh Glob! This feels too good Marcy pull out before I cum!" Finn yelled out in-between moans as his member twitched wildly against Marceline's walls. Marceline only giggled as she floated up slowly then slamming herself down causing both of them to scream in pleasure as they orgasmed at the same time, her body being filled with the heat of Finn's human seed.

Finn could only pant and stare up lovely at Marceline as his mind raced. "I-I…. just knocked you up. I couldn't resist I'm sorry Marcy." Finn stuttered as he spoke with a dejected look on his face. Marceline only giggled teasingly causing Finn to raise an eyebrow. "I'm not going to get preggers ya flipin cutie. I got a pill from Bubblegum when we went to turn in that crown to the Candy Kingdom. That brain lord sure can make some wicked creations, she said it prevented impregnation by one-hundred-percent for an entire week. She said she predicted something like this and would want us to prepare properly." Marceline blushed at the thought of raising a family with Finn. Finn then smiled and pulled Marceline into his chest, which caused them both to laugh and smile as they held each other close and slowly passed out naked on the bed of dirty furs.

A pair of red eyes was glaring at the tree fort from afar, red streams of electricity crackling in his white mohawk hair. "You fucking disgusting mortal. You will pay for defiling my Mar-Mar!" He screamed out in malice for no one to hear or even care about. He then let out a growl as he placed his head on his hands. "Yes I know I can't attack until tomorrow, I won't be able to destroy that fucking mortal and his existence without the cursed relics, my potions…. Yes, yes I was getting to that…. And your grand artifact." The pale humanoid that had stalked the couple before spoke in a crazed yet jealous tone, his appearance was different besides both his eyes being red and having the ominous lightning bolt symbol in both pupils his hair also stood up as if conductors for the electricity that spread through it. He couldn't resist laughing like a lunatic as he held up a blood red spear the weapons length being seven feet long from the bladed head to the end of the shaft. The shaft of the weapon was a rune covered spiral of a mysterious red metal. The tip of the weapon curved out two sharp horns at the base of the blade as the main point continued to twelve inches in length in the shape of a sharp spade. The middle section of the blade was the same red metal as the shaft of the spear. Yet the horns of the blade were covered in copper plating. The weapon was struck with a tremendous bolt of blinding white lightning that soon darkened into a red shade and seemed to be absorbed into the weapon, its runes glowing as the electricity coursed around the metallic spear, the humanoid appearing unharmed as a wide grin spread across his face. "Soon, you will never forget the name 'Ash' as I send you to the afterlife…Finn the Human!" Ash screamed out toward the tree fort as lightning thundered around the grasslands, muffling his voice easily with the roar of nature.

Across Ooo a tired princess was banging her head on her desk as she looked at her stack of paper work. Her bubblegum hair messy from days of lab work. "This sucks." Bubblegum stated blandly with a sigh. She spun around on the lab chair trying to collect her thoughts on recent events, as she zoned out she bumped into a large metalic object, causing her to scream out profane words in another language as it hummed to life with an energetic buzz. As she caught her breath and sighed she tore the tarp off the weapon she was creating, it was a large rifle, much too big for her to carry on her own, its framing was made of the same enhanced steel as the barrel, and it had many lights and electronics across the sides of the weapon. The weapon's was shaped like a highly advanced rifle with an oval shape and arch that served as the rail for a highly powered scope. The stock of the weapon seemed to form into a cylinder before becoming a flat oval at the end. The trigger was even larger than Bubblegum's entire hand, the Barrel of the weapon was shaped like a hexagon and had small vents across it to help cool it after firing. Yet the parts the made her impressed with herself was a glowing set of many small metallic rotors spinning rapidly around a small blue ball radiating energy. This piece was separated by glass made out of enhanced diamond that took Bubblegum an entire year to make. Yet the thing that she stared at with wonder was the blue energy. "I can't believe I actually finished the energy acceleration core. Now my rifle's energy projectiles will be beyond the power of the weaponry that my Gumball Guardians have. Human's really were a terrifying force. Sadly their scientists couldn't finish the entire blueprints since they didn't have the resources… or the time during that horrible war." Bubblegum shook her head as she let out a sigh. "Alright enough rambling, I need to get back to work before Peppermint scolds me for not doing my job as Ruler of the Candy Kingdom again." She rolled over to her desk, letting her gaze escape from her weapon of mass destruction as it powered off, growing cold and silent. "I hope Marceline actually used that pill I gave her, last thing I want is for a war to come around and have their children involved... Plus im not ready to be a godmother yet." Bubblegum stated to herself, not afraid to vocalize her thoughts in her own laboratory.

Several hours in the middle of the night Peppermint Butler came into the lab with a knock noticing the Princess passed out at her desk with all of her paperwork completed. She was clutching tightly onto a picture of her, Marceline, a younger Finn and Jake all together smiling like a family. It was what she considered the closest thing to a family besides her brother Neddy. Peppermint only smiled as he placed a blanket over his ruler and creator. "Sweet dreams Milady, I hope that we can all survive the coming storm…" He whispered plainly before he left the room.
