Title: The Green Monster

Summary: Oncie was able to have such a great rise and fall thanks to the Green Monster that lives inside him that no one else could see until the end…

Kyah! I too love Oncest now (like most people ha!). I know Dr. Seuss is probably rolling in his grave at the thought of the Once-ler becoming the sexual object of thousands of teenage girls… but they shouldn't have made him so darn cute! I think there needs to be a short film done about his travels with Melvin (like 15 to 30 minutes long). I would love to see him again in another film. :) I personally perfer him when he's innocent and more care-free, but I can't deny that he makes an ultra-sexy business man.

This is partially inspired by the video on youtube "Super Psycho Love Oncest" made by Professor Tophat. I love that video... its just so fitting. XD

Notes:
1. Oncie is the more innocent Once-ler who is seen in the film dressed in the gray vest and striped pants. When I'm talking about the one who wore that awesome green jacket, I will use the name Once-ler. I don't really like Greed-ler or any other names like that personally, but I can understand why people would use them to lessen confusion. Self-cest tends to complicate things. XDDD
2. There are no lemons for this chapter (a little bit of kissing though so that fans aren't too disappointed), but there will be in the next one. ;D I love the idea way too much to not include lemons.
3. Since I have been asked this in my other fics from other fandoms, please feel free to translate this fanfic into any language you please. I don't care just as long as you mention it is written by me. :) Spread Oncie-love all over the world bitches!
4. I plan for this fanfic to only be 8 chapters long. Sorry if you expected more!
5. This fanfic kind-of mixes stuff that happened in the movie, but doesn't follow it too accurately. Sorry if that ticks you off! I just thought that events would be slightly different with another Once-ler in there.

Chapter 1

The chopping of the truffula tree did not only trigger the arrival of the legendary, slightly annoying guardian of the forest, but also another creature. Oncie did not know the exact date when this being came to be, but it was obvious that this thing was different from anything he had ever encountered in his life.

It was a chilly night in the colorful forest. Oncie was preparing to go to bed after a late night of designing his new invention. He was not accustomed to being awake this long, but he thought that innovation and genius did not wait for the rising sun to dictate their pace and neither should he.

The young brunette had brushed his teeth until they were as white as paper, and the last thing needed to do when it came to his nightly routine was to change into his light blue pajamas with yellow bunnies printed all over. He quickly removed his gray vest and set it in the laundry basket to wash later. Oncie did the same for his shirt, but once the article was in the hamper he heard a loud wolf whistle in approval. The lone man turned around and saw nothing at the entrance of his bathroom. The up-incoming entrepreneur shrugged it off and suggested that a mix of his lethargy and his mind playing tricks on him was probably the reason for the noise rather than an actual entity. Oncie began whistling an old tune he used to hear on the radio as he dropped his pants. When the garment was dropped below his ankles, the lanky man felt a firm hand grab his exposed buttocks. He jumped and held his behind to defend it. The brunette turned around only to see air. Did he imagine the whole experience?

"Okay, I'm not staying up late ever again. This is messed up." He will never understand why people would want to stay up late if they hallucinated sounds and touches that were grounds for sexual harassment. Not wanting to prolong the odd sensations he was feeling, the young man swiftly in record speed put on his pajamas and walked into his bedroom.

He checked his blueprints for his invention one last time, swearing his saw something move in his peripheral vision but knew he was probably being delusional again. When he decided that it was getting too late and turned to get into his bed, he froze. There was someone sitting on his bed.

They were clad in a well-tailored, bright green, pinstripe jacket that had a length tailcoat. Normally such a garment would be too overpowering for the usual individual, but this man even while sitting looked incredibly tall in stature. Oncie did not know if it was the man's height in general or if it was the shiny top hat with the matching green, velvet bow that made the person appear tall, but they seemed at least two inches taller than he was. Underneath the signature coat was a simple button-down shirt with a large, black and green striped tie that matched the color scheme of the hat. The other male also had better fitting, dark slacks that hugged his developed thighs and went down to his ankles that revealed his expensive footwear. Shiny, patent leather boots that had a slight heel to them would probably make the stranger another inch taller than Oncie.

"I really enjoyed the show. Why did you stop so soon?" The being said, looking up at Oncie but he had his eyes hidden by large, flamboyant sunglasses.

"Excuse me, since this is my home and all… who the hell are you and what the heck are you doing watching me change in the bathroom?" He shouted. It was an acceptable reaction. Oncie was supposedly the only human living in this forest, and even if he weren't, most people would respect one another enough to not barge into each other's homes and watch like a predator. The figure though smirked at Oncie's confusion and anger, and chuckled as he put away his large sunglasses.

"Oh Oncie, I would have thought the sleek, black hair and the killer body would have been obvious. I'm you, the Once-ler…" the other smiled more genuinely, but not enough to comfort the slightly smaller man. His piercing blue eyes were the same color as Oncie's, but they did not have the sparkle his had. There was no innocence, only perversion.

"What? You can't be- how is that- what?" The green-clad man chuckled and got up from the bed to kneel down beside the other.

"Do not try to over think this concept. I'm you, but different. I am here to help you become the great man you want to be. But I don't want you to think about that tonight. I just want to feel your skin." The creepy intruder purred and rubbed his finger against Oncie's exposed ankles. Oncie attempted to kick the man who could pass for his twin in the face, but was instead pushed to the floor.

"Ah, I see what I'm doing wrong. Little Oncie wants the Once-ler to be rough with him. Okay, I'll play along…" The entity smirked and leaned in to bite the other's collar bone, but was held back through what little strength Oncie could muster in his fatigued state.

"No! No! I don't want this! Leave me alone!" Oncie cried to the Once-ler. He closed his eyes so that he couldn't see the well-dressed man, and screamed as loudly as he could. The slightly shorter man thrashed under the intruder, not wanting to reserve any energy for anything but escaping the other's grasp. It seemed as though the other would win, but he heard a loud gasp come from the green-clad man. Suddenly he heard his bedroom door open and he no longer felt the weight of the man with the green jacket pinning him down anymore. Instead, he was greeted by the sight of a sleepy but concerned Lorax.

"Beanpole! What are you doing writhing on the floor like a lunatic this time of night?" The Lorax asked. Oncie sighed. He usually found the orange furball a nuisance, but today the guardian of the forest was his savior.

"There was a man dressed in a green jacket that attacked me! He looked just like me but wore a lot of green and glittery sunglasses. You didn't see him?"

"Naw, I opened the door and saw you screaming. I think you need some rest skinny." The small creature yawned and scratched his mustache. "Now go to sleep. It's way too early to be energetic. Even the birds aren't up at this time."

Oncie nodded. It must have been the full moon and the late night air that has been getting to him.

"Oh Oncie, I haven't left. He just can't see me." The intruder said sitting calmly in the spare chair next to the bed. The young man gasped and turned to the Lorax, but the forest critter only rubbed his eyes.

"What? You alright kid?"

"You can't- uh… you know what? Just go back to sleep Lorax. Sorry for waking you up buddy. Go on, the voice of the trees needs his rest too." The entrepreneur said to the forest guardian as calmly as possible. The Lorax nodded and said goodnight to his good friend (despite how much he denied this fact) and went back outside to sleep. Once the furry creature was away, Oncie turned to the intruder and stared down at him as best he could.

"Aw, you look like you don't want me here Oncie." The Once-ler said with sarcasm.

"Jeez, I wonder why I wouldn't want some guy that looks like an evil version of me trying to rape me." Oncie growled and balled both of his hands into fists.

"Oncie, you're being too mean to your house guest. You know your mother raised you differently. I think you need to be punished…" The intruder began to approach him but Oncie put his arms up and stopped him from coming closer than arms' length.

"No! Absolutely not! Look… I just want some sleep after working on my thneed. I really don't care what the heck happens in the morning but please! I need some sleep." The shorter said. He thought that perhaps with some sleep this delusion would end.

The Once-ler pondered the offer the more innocent one made.

"I guess I could molest you in the morning. You look so cute with your hair tussled about." The intruder said almost drooling with lust. Oncie groaned in disgust and shook his head. This imagination of his led him to creative and genius ideas, but they could also apparently manifest into devious perverts that could not keep their hands off him.

"Whatever man. I am going to sleep."

"Can I sleep with you? I promise I won't bite you… yet." The green-clad man chuckled.

The man in pajamas sighed and said "Whatever! Just don't… urgh okay, going to shut up and sleep now."

"Aw, wuvles you too sweetie!" The Once-ler smiled and laid down next to his doppelganger. Oncie could hear the other removing his bright green gloves, sparkly sunglasses, hat, and the ornate, large coat, draping them over the chair.

"Urgh, you need a larger bed." Oncie rolled his eyes.

"Deal with it."

"Hm… so you're really serious about me not molesting you right now? I mean, I just have this strong urge to twist your nipples and-"

"Need sleep damn it! Just be quiet and no touching." Although he said that as intimidating as he could, the taller of the two could not help but giggle.

The next morning, Oncie woke up facing the wall of his simple cottage. It was unusual since he liked to sleep in the middle of his bed, but did not think anything of it and shifted closer to the middle. However, he could not move much further because there was another body right behind him. His eyes shot up and he turned to see the smirking face of the lecherous doppelganger from last night.

"Oh Oncie, are you flirting with me now? You're so cute, trying to be coy like that. You look like such a good boy but deep down you're naughty." The Once-ler grinned and snaked his right arm around the more innocent man. Oncie sighed. It appeared that his delusions were here to stay.

"Look, do you have to keep on touching me? Hey! I know what you're trying to do! No ass grabbing!" Oncie warned.

"You can't possibly expect me to hold that promise, do you? Your body is so delectable." The Once-ler gushed but kept his slim fingers higher up on the other's back as Oncie requested.

"Dude, you are the creepiest thing I have ever imagined in my life. First off, why do you want to have sex with a guy who looks like you? Second, why guys at all? And finally, why the hell are you bothering me of all people?" The doppelganger got up and put on his stylish coat and opera length gloves.

"You have to admit, we're just better looking than most people. Some might criticize that we're on the skinny side, but I like people a little leaner than some. Also, there just isn't anyone good enough to be with us except... well, you get my point. I want someone as close to me as possible, which is me or you Oncie. As for guys in general, I have a distaste for them actually. Most are stammering, idiotic baboons like your siblings. I only like you Oncie." He paused to put on his silk, top hat and glittery sunglasses. "You are the only one that is worthy of my time and you need my guidance."

"I don't need anything from you except to get out." Oncie said. He knew the other wouldn't leave so he just followed his routine. The shorter one rummaged through his dresser to get another set of clothes to wear while going in and out of the house. He sat at the foot of his bed and began to unbutton from the top when he felt two stronger, firmer hands brushing his own away.

"Listen man, I'm really not in the mood."

"I just want you to have your shirt properly buttoned Oncie. You're a special man and you deserve to be treated that way, despite your mother's protests." The Once-ler said as he swiftly undressed the other. He gently draped the white shirt over the other's shoulders, holding it at an angle so that Oncie could slip his thin limbs into the arm holes. Once that was accomplished and the collar stood in a way that pleased the green-clad intruder, he buttoned all of the buttons carefully in order to ensure there would be no wrinkles on the shirt. Oncie couldn't help but blush at the intimate action. Touching other people was not something he was used to due to his mother's favoritism of his older, burly brothers, and the lack of having any close friends except for Melvin the mule. It was nice that someone appeared to care for him, even though it was such a foreign concept to the brunette. Perhaps the visitor wouldn't be so bad to have around if he acted like this more often.

The pants and the rest of his clothing came off and on as easily as the shirt and soon Oncie was ready to start the day.

"I never understood why you wear such drab clothing. You need something flashy, something that conveys how important you are in five seconds." The usually perverted man sighed. He seemed to be almost sad to see the slightly shorter man dressed so casually.

"They're the only clothes I have. Aunt Grizelda made them for me out of Bret and Chet's old clothes." Still, the flashier of the two did not seem pleased.

"You know that you should get the best of everything, even clothes. You're so much better than everyone else." The other said and pulled Oncie into a tight embrace. The Once-ler brushed his fingers into the smaller one's thick, dark hair and breathed softly against his neck. It was odd. No one ever initiated a hug to him before. Oncie was always the one who hugged first.

"Um... thanks I guess."

"Now go to work. I know you can do it." Then with a tiny peck on the cheek, the other vanished into thin air.

"Huh, well at least it's nice to hear someone have confidence in me." Oncie smiled. For some reason, he felt more giddy after the hug and rushed outside with a chair, a spinning wheel, and the bag full of truffula tufts. He needed to spin the tufts into thread in order to make his fabulous invention.

Just as he was about to spin, he heard a loud voice call out "Beanpole!"

"Oh, hello Lorax. Sorry about last night man, I didn't mean to wake you up." He blushed. The forest guardian shook his head and said that the human sounded like he was in grave danger and that chances like that shouldn't be taken.

"Well, thanks again. So, no hard feelings right?" Oncie asked, making sure the creature wasn't too mad at him.

"Yeah, I'm not mad about last night. I'm still a little pissed about the tree. They feel pain too you know." As usual, the Lorax was going to rant at him again about the importance of not harming the trees. Oncie knew that it was not nice to do so without the consent of the animals, but he did not think that he would get lectured every day for it. So as he half-listened to the orange furball, he spun the tufts into workable thread that he could use to make his thneed. It was after three hours did the inventor finish processing the tufts, but was poked in the head by the annoying Lorax.

"Hey, what was that for?"

"You dozed off. You didn't listen to what I said. I'm warning you beanpole. You will face the consequences if you can't cooperate with the forest's terms." The furry creature leered.

"Alright buddy, you've been saying that for a while now. I think I'm going to go knit inside." Oncie said. As he closed the door though, he realized the Lorax snuck quickly into his house.

"How did you-"

"Remember, you will suffer the consequences!"

"Yes, yes, I understood." Oncie sighed. Could he have a day with no disturbances?

"Could you open the door?"

"Sure Lorax," and swung it open with easy. Once he was sure the orange ball of fluffy was out of the door, he slammed it shut.

"Quite an annoying little guy, the mustache is." It was the Once-ler.

"Oh, you're back again." The naive one wasn't too disappointed this time. The darker and more twisted of the two was really an okay guy when he wasn't molesting him. His reaction to the doppelganger made the green-clad man frown. Was he expected to say more?

"It sounds like you don't miss me enough. I think I need to change that." After that, he swiftly pounced Oncie and held both of his arms above his head. The Once-ler sat firmly on Oncie's crotch in order to ensure that the other could not get away from his grasp. Oncie thrashed as he did last night, but it was no use. He was no match for the slightly more muscular version of himself.

"I'm going to do something that none of those indigenous critters can do for you." And swiftly the larger clone brought his lips against the Oncie's. The smaller man froze as soon as he felt the Once-ler's slick tongue. The flexible muscle thrust between his lips and danced around his own tongue. He groaned in disgust and tried to kick the well-dressed man off of him, but it did nothing. Oncie knew this next tactic would hurt, but it was the only option he could think of. The man below curled his head back slightly and then slammed it into the Once-ler's head above him. This made the Once-ler hiss and created an opening for Oncie to escape. He stretched for his beloved guitar, but he was tackled again before he could get on the offensive.

"This time bitch, don't pull any funny shit or else you'll suffer some ACTUAL consequences. And please, make your mommy proud and move your tongue a little Oncie when I kiss you." The man growled, still angry about getting injured by the other brunette. Abruptly, he jerked Oncie closer by pulling on his vest and locked their lips together again. The aristocratic man's tongue brushed against Oncie's, sending a jolt of electricity down both of their spines. Why did this suddenly feel so good?

The casually dressed man snaked his arms around the other's neck, trying to get even closer. The greedy, sexual deviant wanted more than just steamy kisses and as their lips continued to get even more aggressive, the Once-ler unbuttoned Oncie's shirt all the way down. The man beneath him hissed slightly at being exposed to air, but then a pair of warm hands covered with green, leather gloves ran themselves up and down the naked flesh. The Once-ler though still wasn't satisfied with this and pulled his mouth away from the other man's and nipped on the underside of Oncie's chin. Soon Oncie's neck and collar bone was littered with bright red, almost bruising hickeys, but at that moment he didn't care. All he cared about was the green-clad man's warm mouth trailing down his body and watching him finally reach for the left nipple. He could see the Once-ler playfully swirling the flesh against his tongue, making his body contort in pleasure. Soon the perverted version of himself got bored and switched to the other bud. Oncie even loved the scraping of the Once-ler's teeth against the sensitive flesh, groaning incoherently in response.

The man above the up-incoming entrepreneur pulled away and leaned up again. Oncie thought that he wanted another kiss but instead the other nibbled on his right ear before he spoke.

"Hm... I think I've had enough fun. Bye, bye Oncie!" He vanished again, this time though he left Oncie with a stiff erection.

"Urgh, that guy is such a jerk!" He growled. The hardened member felt uncomfortable under his skinny pants, but he did not want to risk masturbating in the daytime when the animals could barge in.

"I guess I'll go work on the thneed then." The brunette sighed. His doe wide eyes looked down at the tent in his pants and groaned. Why did that doppelganger have to be so persistent?

"I might as well get into more comfortable clothes then."

The hours of knitting and being in the house in his comfortable pajamas helped cool Oncie down.

"Yes, now that's a thneed. There's nothing unmanly about knitting. No sir!"Oncie said before scrathing his neck. His skin was patchy feeling from all the hickeys the Once-ler gave him.

"God, how am I going to explain all these to the animals? Maybe I'll make up some accident or a large monster that almost killed me. The accident is probably more believable since I'm sure the Lorax knows probably every animal that lives in this forest."

The innocent Oncie did not want to think of those things and thought it was best to go to sleep before the evil clone's return. He easily reached a peaceful slumber, completely unaware that the sneaky doppelganger was watching him from outside.

"Such a cutie... but his mouth tastes so sickeningly sweet like maple syrup and marshmallows." Before he could discuss more about the angelic Oncie, he heard the forest animals scurrying to the cottage. He could hear the brown, furry bar-ba-loots rushing into the house under the instructions of the grumpy expressioned Lorax. While he never understood the orange fluff's need to protect the colorful plants, but tonight the Lorax's tactics were certainly interesting.

The heftiest and strongest creatures in stature were trying to transport the bed outside of the humble home, but the doorway was too narrow. The Lorax shook his head in disapproval, but all the creatures did not respond to any of the Lorax's words. It was a bizarre event unfolding before the impish doppelganger, but he did nothing to stop it. The bumping and shuffling amused the devilish Once-ler, for it made him think about the sounds he expected to make next time with the pure and sinless Oncie.

He could hear the sweet, young man quietly snoring away, completely oblivious to the actions of the animals and his ghoulish invader. It was hard to believe that the chaste and lovely version of himself was already in his twenties. His doll-like eyes and unblemished skin (well, it was untouched before he got to it) made him appear as if he were still in high school. Yet all these childish features on the lofty, fine man made him quite striking to look at. While many people if they were to be able to see Once-ler and Oncie, would think they looked exactly the same, the more depraved one could easily point out the one key difference in them: the eyes.

"Let's try through the window." The Lorax said the the forest critters. They nodded, allegedly not exhausted at all at the task of carrying the bed and it's occupant again. The Once-ler got closer, knowing the cuddly beasts could not see or hear him. He was curious as to why they would want Oncie and his bed out of the house. Surely if they wanted to occupy the house, they did not have to evict the lanky, ebony haired man.

They were able to get the bed outside through the manner of the bending the tent and distorting its windows to accommodate its size. When the bed was fully outside, the bushy degenerates followed the Lorax down the hill and gently placed the bed into the water. The mattress was buoyant enough to float but the Once-ler still worried about the ignorant man on top of it. He raced down beside the river, yelling for the artful, sleeping man to wake up from dormancy. The fashionable man heard the other mumble something about calling him a pervert, but was cast down to see that Oncie still had not awoken. He could hear the Lorax worrying about the stupid animal that was floating with his possession and he wanted to strangle the life out of that miserable, grumpy, orange cretin. Did the mustached baffoon wish to drown the good man?

The creatures tried as best as they could to rescue the young bar-ba-loot, but the tiny animal appeared to be quite stupid and did not want to cooperate.

"And this is why I never liked nature; animals are so freaking stupid." Once-ler griped. He called out for his counterpart again, but Oncie shifted in his sleep which caused the course of the bed to alter onto a more dangerous path. The Once-ler was here earlier while he left Oncie to spin thread outside,

"Oh good god, Oncie wake up! Wake up now!" The evil complement cried. The bed flipped over due to the current becoming more ferocious, and it triggered the young brunette to wake up.

"Ah! What's happening? Where am I? I- oh my god." He said after realizing that his bed was flowing down raging rapids.

"Hey! We've got some trouble kid, but don't worry kid! We'll get you." The Lorax said, not sounding reassuring at all.

"Christ I'm in a river, help me!" Oncie bawled. The mattress bobbed frequently, slamming against jagged rocks and flowing even faster than before. The freezing, white waters of the rapids drenched the powerless young man, making his shiver with both fear and cold. Oncie clung tightly onto his bed, desperately trying to make sure he didn't jerk around too harshly in fear of injury or worse.

"I need help!" Oncie screeched. He felt a warm body press against his cold back.

"Don't worry, I'm here." The Once-ler whispered. Oncie blushed, remembering the events from before. While his skin felt icy to the core, the core of his body was boiling like magma.

"They can't see me, I promise. Just try to stay calm."

"Uh, kind of can't dude." Oncie moaned.

"Why?"

"Uh... well, oh dear... look what's in front of us." It was the mouth of a large waterfall waiting to toss both Once-ler, Oncie, and the tiny bar-ba-loot to their deaths.

"Oh my, well, I suggest you start paddling as fast as you can with that pillow of yours." The green-clad businessman encouraged.

"Gyah! Help us!" Oncie pitched to the Lorax as he attempted to paddle for his life.

"Just a minute!" the furry ball cried and flung a giant boulder to them. The massive rock crashed onto the bed and catapulted all three of them onto nearby land. The young bar-ba-loot brushed off some of the water droplets and strolled calmly over to his friends, but Oncie was not breathing. The Once-ler scowled and screamed at the Lorax (even though the forest guardian could not possibly hear him) "You fucking shaggy piece of shit! If Oncie dies I will wring your fat neck!"

As if the orange guardian did hear him, Lorax immediately initiated CPR onto the unconscious human. When that procedure did not work, the Lorax in a flash grabbed two of the smallest fluffy creatures and rubbed them together to create static electricity. When the two bar-ba-loots came into contact with Oncie's soaked skin, it jolted Oncie upright and he was fully awake and breathing properly again.

"Ah! Hahaha, oh god... I was about to go toward the light, but you pulled me right back and here I am! You saved me! Thank you, thank you, thank you!" Oncie cheered and pulled the forest protector into a crushing hug.

"Oh yeah, heh... it was no big deal."

"It is a big deal! I almost went over that waterfall. Wait... how did my bed get into the water?" The brunette turned quickly to his devilish, and really angry version of himself.

"It was that stupid Lorax that almost got us all killed." Once-ler growled, clutching his wet, tailored jacket. It would take forever for it to dry without shrinking.

"Lorax, how did my bed end up in the water?" Oncie asked.

"About that beanpole... I kind of put your bed in the water. But I didn't mean any harm." The usually happy brunette immediately let go of the orange hairball and glared.

"I'm sorry! I did not want to hurt you. I just wanted you to go away. Everyone here needs the trees and I can't have you chopping them down. So... we kind of have a big problem." The Lorax said honestly. While Oncie was still upset at the creature, he was not going to follow the advice of the Once-ler and "squish that mustached freak until all the blood and guts squirt out."

"Okay, how about this? I hereby swear that I will never chop down another tree. I promise." The nicer of the two said, kneeling down so that he was eye level with all of the forest animals.

"Thank you. But we'll all be keeping an eye on you."

"Great, well I'm going to sleep... right after I find my bed." Oncie sighed. Once the drenched young man knew the indigenous life was no longer looking, he walked up to the still angry doppelganger.

"Look, I know you're upset with the little guy-"

"Upset? He tried to kill you! If he is the actual guardian of the forest, why doesn't he just plant another freaking tree into the ground? Huh?" The Once-ler snarled.

"Hey, come on... please don't be angry at them. I... I'll let you hold me while we sleep tonight if you help me find my bed." The green-clad man raised his eyebrows in curiousity.

"You promise?"

"Yes, I promise- whoa!" Oncie gasped before he was dragged into an intense kiss. It ended as quickly as it started before the Once-ler made him sit down on the ground and told him that he would fetch the bed before midnight.

End of Chapter 1

Gyah! I want to write more! But I think that would make the chapter too long and I think this is a nice break. :) Please read and review! This is my first Oncest story and would really like to know what you think. I'm going to work on chapter 2 right as soon as I post this story!
