I am Finn The Human

Waking up, he groggily sat up rubbing his head and looked around to find himself in an unfamiliar place. The young man had blonde short hair and a handsome face with a lean physique.

"Finn! You're awake!! Thank goodness!!" A voice came turn to see yellowed talking humanoid bulldog.

"J-Jake?" Flashes of images appeared in his mind as fragmented memories resurface in his mind. These were memories of a man who had passed away and possessed the body of Finn "The Human" Mertens.

He feels baffled at the situation, then another memory unfolds and sees that before possessing Morty, he receives some cheat and power to help him in this new adventure.

"Yes, it's me! I was worried sick after you hit your head." Jake sighs in relief and quickly checks up on Finn.

"How long was I out?" Finn asked.

"A day or two. How are you feeling?" Jake asked.

"I'm fine now. Just need to rest a couple of minutes then I'm good to go. Though, I won't lie, I'm quite hungry." Finn said.

"Alright, I'll still need to call Doctor Princess and tell her you're awake. In the meantime, wait here and I'll bring some food." Jake said.

"No worries." Finn said as Jake left him alone in their room. The human boy laid back on his bed trying to organize his thoughts.

'Okay, so I'm now Finn from Adventure Time and from the looks of it this place is an alternative version of Ooo.'

One of the major things is that the Ice King is genderbend into the Ice Queen and many princesses are sexier than their canon counterpart.

'This is good, if I play my cards right then I'll be having my own Harem for women!'

The person who fused with Finn isn't a good person but isn't a bad either and he aims to indulge himself with the woman of Ooo even including Finn's mother Minerva if possible.

'Let's see, I have Cheat Ability from Essence of Archmage, Hentai Bastard and Mad Doctor.'

He received boon before arriving and acquired these abilities that gave him certain overpowered powers.

[ A/N: I won't put it here cause it's long as fuck. Just look it up in CYOA essences ]

Finn decided he would be better than the canon Finn and done what he should have done. He got into his feet and inspected his body. His age was around 12 years old yet was lean showing off his impressive muscles despite how the show depicts it.

Without his iconic hat, he has messy blonde hair and shockingly blue eyes. He had a physique similar to Killua from Hunter X Hunter. Finn pulled his shorts and saw a long and girthy penis easily eight inches flaccid and likely to reach twelve inches when erect. It is also strangely uncircumcised.

'It should take a bit before Jake arrives. Let me try experimenting using my ability.' Finn was easily able to understand the scope of his newfound abilities and used Mad doctor essence which basically gave him the ability to form any potion he likes and conjure the material needed for them.

He created potion template of characters that he like to have their power from [ Almighty ], [ Super Vegeta Template ], [ Super Goku Template ], [ Absolute Swordsmanship ], [ Absolute Martial arts ], [ Status System ], [ Quest System ],[ Beelzebuth, lord of Gluttony ], [ Shub-Niggurath, Lord of Harvest ], [ Gilgamesh ].

Finn now exudes a different kind of air as he became insanely powerful that there won't be anyone capable of stopping him.

"Nice, I can enjoy my adventure without worries. Status."

The status was simply for show and Finn was still going to hold back and enjoy the thrill but didn't want to lose against anyone.

"Now, I'll try making a weapon later." Finn was excited about what he needed to do from now on. He can easily travel to another dimension if he wanted but decided to explore the land of Ooo for the time being.

Finn used magic and created clothes that he was familiar with which consist of blue shirt, navy cargo shorts, white long sleeve and his hat. It felt familiar to him and decided to use it. Few minutes later, Jake came inside and brought his food.

"Here's your food, Finn." Jake handed the tray, it was a simple meal with eggs, sandwich, and juice.

"Thanks, Jake." Finn began to eat, enjoying his food.

"Alright, just eat up. I called Doctor Princess and she will be here in around five minutes from now." Jake said and Finn smirked when a panel screen appeared.

"Seriously, are you alright now, Finn?" Jake asked.

"Yeah, it's nothing I can't handle." Finn said immediately using his [ Almighty ] ability briefly gained multiple pupils, selecting a future to make Jake leave the tree house and have privacy with Doctor Princess.

At that moment, Jake received a call and quickly answered. He sounded worried then looked at Finn.

"Who is it?" Finn asked despite knowing who it was.

"It's Lady Rainicorn. I forgot we arranged a date today and I'm worried she'll get mad if I cancel it." Jake said.

"Then why don't you go? Like I said I'm alright now and Doctor Princess is coming over so I won't be alone. There's also BMO." Finn said.

"You sure? I think Lady Rainicorn would understand if I explained it." Jake suddenly jerks when Finn grabs him by the shoulder.

"Chill bro, nothing is serious and I'll call you if something happens. Just enjoy your time with Lady Rainicorn." Finn said and normally this won't work if logic was in play but his Hentai Bastard essence is working flawlessly in his favor.

"Alright, I'll go once Doctor Princess is here." Jake said.

"That's cool." Finn recalled she isn't even a real doctor yet still ballin' her way. Her name is simply Doctor.

"In the meantime, why don't we play some cards?" Jake suggested.

"Sure." Finn answered and the two played some simple game to pass the time until Doctor Princess Arrives.

It didn't take long for her to arrive and Finn saw a young woman who wore blue-tinted glasses, a red jeweled head chain, a pair of low-heeled brown shoes, and a doctor's coat with an orange, long-sleeved turtleneck dress underneath. She has greenish skin with a few freckles on her cheeks, and her brown hair is in pigtails. She has a small, pink Scientific Parasite in her left pocket. In honesty, she looks cute.

'Oh my, was he always this good looking?'

Doctor Princess felt her face heat up upon seeing Finn. He looked a lot more mature than the last time she saw him.

"Hello Finn, I'm glad you're awake. How are you feeling?" She asked, walking over.

"A lot better now that you're here." Finn subtly flirted with her that went unnoticed by Jake but Doctor Princess' heart skipped a bit.

'Did he just flirt with me? No, I'm probably just overthinking this.' Doctor Princess used her stethoscope to check on Finn.

"Well, I better get going. Just call me if you need me." Jake said.

"Don't worry, I'll take care of Finn." Doctor Princess said and Jake nodded.

"Okay, I'm trusting you doc." He reluctantly left Finn with Doctor princess. She felt her mind going numb when looking and touching Finn.

"Can you remove the shirt for me?" She asked.

"Ah, sure."

She was stunned upon seeing Finn shirtless showing off his shredded body. Doctor Princess felt her loin started to grow wet as she began to touch his body.

"Y-You seem a lot healthier than I expected. Tell me do you feel any pain somewhere?" Doctor Princess' breathing was growing sharp as she was under Finn's pheromones.

"Well…" Finn acted like he was reluctant but he was simply wanted to play with her.

"Don't worry, whatever it is, I'll try my best to help." Doctor Princess said unaware what's to happen.

"Are you sure?" He asked.

"I am. Just trust me." She said and Finn nodded as he removed his shorts that caused her to gasp.

'W-What! Is that Finn's penis!?' Doctor Princess swallowed her saliva as she was mesmerized by the veiny cock in front of her.

"Then can you suck my dick?" Finn bluntly asked and this caught her off guard.

"W-What? Finn, don't joke around." Doctor Princess said trying to keep herself composed but can't take her eyes off of his dick.

"Didn't you say you'll help me? It's been like this since I woke up and it started to hurt." Obviously that's a lie and simply guilt trip her. Doctor princess contemplated if he should do what she asked.

"Uhmm…okay. I did say I'll help you the best I can." Doctor Princess, her curiosity and professionalism warring with the sudden and intense arousal coursing through her, knelt down before Finn.

She tentatively reached out, her soft, green fingers brushing against the velvety skin of his impressive shaft. Finn groaned as he felt the warmth of her breath against his sensitive organ, watching her intently as she studied it with wide, doe-like eyes.

'This musk is making me lose my mind but I want to taste his cock so bad' She thought as she began to stroke it gently, her touch both inexperienced and incredibly arousing.

The room filled with the faint sound of her saliva mixing with the smack of her hand moving rhythmically up and down his length.

With a deep breath, she leaned closer, her tongue darting out to taste the salty precum beading at the tip. The sensation sent shivers down his spine, and he knew he had to have more.

He urged her on, his hips moving slightly to encourage her, as she took him into her mouth, her plush lips stretching around his girth.

She tried valiantly to take him deep, her eyes watering with the effort, but she couldn't help the moan that escaped her as she felt him fill her mouth completely.

The smell of his arousal mingled with the faint sweetness of the potion he had made earlier, driving her wild with desire.

Finn's eyes rolled back in pleasure as she bobbed her head, her throat muscles contracting around him, the wetness of her mouth creating an exquisite friction. He was in heaven, and he hadn't even begun to explore the full extent of his new life in this sexed-up version of Ooo.

Finn's moans grew louder and more needy as Doctor Princess continued her enthusiastic ministrations, his hips bucking slightly with each bob of her head.

"Oh, yes, Doc, that's the spot," he murmured, his hands tangling in her hair to gently guide her. He watched her eyes water around his cock, her cheeks hollowing as she took him deeper, and he couldn't help but feel a twinge of pride at his newfound power over her.

"You're doing so good," he praised, his voice thick with lust.

"Your mouth is so warm, so wet...it's perfect." Each word was a caress, a whispered promise of more pleasure to come. Her eyes looked up at him, filled with a mix of shock, embarrassment, and a fiery passion that only grew brighter as she took him even deeper. Her tongue swirled around the head of his cock, teasing the slit, and he felt his orgasm building like a storm.

"Swallow it all," he instructed, his voice a low growl.

"Every drop." And with that, he released himself into her mouth, the hot spurts of his seed hitting the back of her throat, making her gag slightly. But she took it all, her eyes never leaving his, and he knew in that moment that she was his. He had claimed her, and she had accepted it willingly, if not entirely consciously.

His grip tightened in her hair as he emptied himself into her, the intensity of the experience making his head spin. As he came down from his high, he petted her cheek, a smug smile playing on his lips.

"Good girl," he said, his voice still husky with desire.

Doctor Princess's eyes widened as she swallowed the last of his cum, the potent taste lingering on her tongue. She felt a strange warmth spreading through her body, and she knew it was the aphrodisiac effect from his semen.

Her cheeks flushed a deeper green, and her breaths grew ragged as she felt her own desire spiral out of control. She looked up at him with a mix of confusion and arousal, not quite understanding what was happening to her, but unable to resist the urges coursing through her veins. Finn took advantage of her vulnerable state and whispered,

"Do you want to try tier 15?" His voice was like a siren's call, beckoning her to give in to her desires. Without a moment's hesitation, she nodded, the word

"Yes" escaping her lips in a breathy moan. Finn's grin grew even more predatory as he watched her stand up, her legs wobbly from the intense need coursing through her body.

She began to undress, her hands trembling as she removed her doctor's coat and dress, revealing her lacy lingerie. Her breasts were a perfect handful, her nipples erect and begging for attention.

Her hips swayed as she stepped out of her underwear, her bare skin glistening with the sheen of sweat. He took in the sight of her, feeling his cock stir to life once more at the sight of her bare pussy, already slick with her arousal.

"Good," he growled, his eyes never leaving hers.

"Now, let's see if you can handle the real deal."
