It was largely clear to everyone at the Academy of Ooo & Aaa (pretty popular for being insanely and incredibly awesome, hence the name of the place) that there was a slightly pervy relationship going on with the junior Finn Mertens and the senior Marceline Abadeer (vampire, local punk rock heroine), but that was probably pretty normal, Finn had the dubious honor of having some of the most convoluted and extensively (and envied, in many quarters from both guys and ladies) romantic and sexual relationships around.
Confirmation, though, is always nice, and the academy body’s lust for gossip was satisfied when the Finnceline pairing (as the local newsblog, run by Lumpy Space Princess and Lady Rainicorn, called the potential romantic friendship with benefits of Finn and Marceline) was confirmed on the first day Finn went swimming after he and Marceline got serious.
The academy had a rather nice pool, a big scoop cut out of the ground and screened over with concrete before water had been poured in. It dipped and rose in unpredictable places, giving it plenty of depth for the high and low diving boards put everywhere. A small tide generator amused a few people who really liked that sort of thing, and near a portion of artificial sand at one corner of this huge pool had been Finn, a short and stocky boy of who-knew-how-old-he-was, famous for being one of the prettiest people on the whole campus. He’d been chatting amiably with his friends Marshall Lee and Bubba Gumball (themselves good friends and maybe lovers of Finn’s best friends Marceline and Bonnibel Bubblegum), when the hub-bub started.
In the end, it all came down to him taking his shirt off and exposing his plump body. That alone wouldn’t have been a big deal most of the time, and Finn had been only half-listening to the usual buzz of conversation and splashing going on around him, and stopped when he realized that all of it had, at least in the area immediately around him, stopped. It was like throwing a rock into a pond and seeing the ripples. His shirt had come off, and the people directly behind him had stopped talking. Others had noticed, and they also stopped to stare, and those people stopped, and so on until Finn was surrounded by a gaggle of curious onlookers.
He didn't really notice until he had wrapped his shirt up and thrown it onto a chair, and then saw Gumball looking at his back with a frankly astonished and smug look. "What?" Finn said.
Gumball glanced at Marshall, and said nothing. Marshall looked, and gaped. Both boys glanced at each other, looking awkward. Eventually, someone that Finn didn't know said, "Dude, did you get, like, sexed up by a mountain lion or what?"
"...Huh?" Finn said, blinking.
Someone snickered. "Dude, you got, like, molested," Marshall said, with his usual absence of tact, pointing at Finn's back. There were bruises everywhere, small and faint in the shape of a woman's hands - not like he'd been slapped, but gripped by someone who was extremely strong - and there were a lot more of them around his lower back, dipping under his waistline. There were even a few faint nail marks, or rather claw marks, and more astonishing were the bite marks all over his shoulders and neck, still a bit red and half-healed. They had been downright bloody not too long ago.
The laughing and bad jokes started, but not before Finn’s good buddy and teammate Stave Rogers came up to Finn, bobbing and nodding, and said, "Oh my gosh, Finn! What did Marceline do to you?"
"What are you talking about?"
Steve pointed incredulously at Finn’s back. "Seriously? Look, she's been totally eating you alive! You let her feed from you?"
Finn shrugged. "Sure, why not? She's my girlfriend." Technically, they'd been that for a short time, but it was still a fairly novel statement.
"She's a vampire."
"Yeah. I figured, she needs blood, so why not go with me?"
They stared at him. Gumball smirked. Another one of Finn’s teammates, a rich gearhead named Tony Stark, snickered. "I knew it,” Tony said. “Called it! Look at me, look at me here calling it; Marceline is a very... domineering woman. I hope someone picks up that phone!"
“Uh,” Finn said.
“BECAUSE I TOTALLY CALLED IT!” Tony said. He clapped, bowed out, and went to wherever it was he deemed it important for him to go.
"Well, sure," Finn said. "But I don't...oh."
Marshall laughed. "Marceline plays rough. Bet you bottom all the time."
“Yeah, I do, I like that- DANG IT!” Finn turned bright red, and he was soon surrounded by a lot of other guys, a few commiserating with him for having such a rough love life and it was cool of him to let his lady have what she wanted, most of them congratulating Finn for being such a badass and landing the ever-so-dangerous Marceline...and a few who taunted Finn for being a bottom boy.
Finn didn’t see what was wrong with that, or why they were making fun of him over it, and he interpreted it as them mocking Marceline in some reason. There wound up being trouble over a few broken bones, sixteen different bloody contusions, and at least one guy who somehow wound up getting mailed to the distant planet of Cybertron who immediately mailed him back, because in the words of the mighty Autobot named Hound, “We stopped letting idiots come here after we exiled Waspinator.”

Eventually, the rumors spread. Soon enough, they found Finn’s brother-by-deed Jake (who, being a mutant dog, wasn’t his blood brother, but they had gone through so much together that they honestly didn’t see the difference) and he was more than a little alarmed by this.
Granted, this came in the form of Finn’s last teammates, Bruce Banner (presently in his alter ego of the massive green-skinned Hulk) and the sizeshifting Cassie Lang, who bluntly asked him, “You know your little bro's being dominated hardcore by Marceline? She's been biting and clawing your bro up!"
“She likes the ‘om nom nom!” Cassie said, making biting gestures.
“…Don’t think that’s helping,” Hulk said, watching Jake fall flat on the floor and flop about gasping in total existential horror for a few minutes.
“And saying it like you did does?” She said skeptically.
“…I was channeling Joe Fixit for a second there, give me a break,” Hulk said, having the dignity to look embarrassed.
On the bright side, though, after Jake recovered from the knowledge that Finn had basically admitted that he was no longer a virgin (though, given what he and his many ladyfriends got up to, Jake had assumed that he hadn’t been for a while), he had made what he thought was the logical response and gone straight over to Finn and gave him a thumb's-up. "Dude," he said solemnly. "You are straight-up hardcore. Welcome to manhood, buddy! Marcie's gonna freak when everyone finds out!"
"Dude, everyone, like, always suspected," Loki said from atop Finn’s head, having transformed himself into the world’s dorkiest hat in a really dumb attempt to discredit Finn and refusing to get off. “But I never thought the rumors were true! They were so twisted, so sickeningly domineering, so… interestingly inventive in ways of violating the male body! I am honestly fascinated. What kind of lunatic would come up with those?!” They stared at him. “Besides me, obviously.”
“Uhh,” Finn started. “Um. Actually, Marceline started those rumors," Finn said honestly. “From experience, she didn’t make a lot of stuff up- oh dang it I SHOULD NOT HAVE SAID THAT LAST PART.”
“WHAT,” Jake said flatly.
After that, it was a short stop towards discussing it with the woman in charge of Finn, his caretaker (and, Jake was certain) the woman who had introduced him to life without virginity, Susan Strong, an absolutely gigantic woman whose sheer size difference had dissuaded Finn one little bit.
"Yo," Jake said with a great air of seriousness to Susan.
"Hi-yah," Susan said kindly, bending over to see Jake properly.
"Ya know that your boy-bro's been deflowered by Marceline?" Jake asked her. "She's a rough girl. He's got like bite marks and claws and stuff! And nasty stuff going on! Nasty! Nasty-nasty! Why am I repeating it like that? Dang it, Prismo, you’re a bad influence on me! …Prismo, if you’re listening, don’t take it serious, mang, that was just a joke!"
“Oh, I know,” Susan assured him.
“Say what?” Jake said.
Susan clapped her hands, her massive shoulders shrugging. “Marcie, she ask me first. She say, "I can has Finn please? I hug and eat and squeeze, but I no hurt him and keep him happy-safe forever.' So I say, 'okay', and is fine." She shrugged. “Is love. What the problem?”
"...Dude, Marceline cleared herself before she made herself a total dom all over your boy?"
"What 'dom'? Is it eatable?"
"Never mind, girl." Jake turned around and huffed.
Susan giggled, a frighteningly knowing giggle. “But dom is fun…”
He gasped and whirled on her. “YOU KNOW WHAT IT MEANS!”
She whistled innocently and wandered away. “Funny thing… I go bye-bye now!” She ran away, leaving Jake in a hissy-fit.

Not much later, probably due to Jake being incredibly bad with secrets, the rumors reached the sugary ears of Bonnibel Bubblegum, part-time mad scientist and full-time science hero, adorable slime girl who’d stabilized her body into a humanoid configuration, the sweet and much adored leader of the smart kids and labeled the Princess of the academy.
(It was also a commonly known fact that Marceline and Bubblegum had an on-again, off-again fling with each other for years; Finn knew about it, and supported it. It didn’t hurt that he himself was involved with Bubblegum at times, and she had been his first girlfriend.)
Bubblegum was one of Finn's best friends, and she was something of a mentor and idol to the younger and smaller boy; Bubblegum had therefore become more than a little protective of the younger boy (though not nearly as much as Marceline was; campus legend claimed that Marceline had literally eaten a bunch of mean girls who'd gotten their boyfriends to beat him up on the first day of school. She did, but she’d spit them out later without chewing them up or anything gross like that), and when she heard that Marceline had a domineering sex life with Finn with a possibility that his consent wasn’t an issue, her reaction was...mixed.
And by mixed, it is meant that she went right up to Marceline and cried, "YOU MOLESTED OUR FINN!?"
"Whoa, Peebles!" Marceline said, dragging her aside. "Chill out, what are you talking about?"
Bubblegum was huffing and growling inarticulately. "I have heard...such terrible things! Do you know what everyone is saying about what you do to Finn...behind...behind closed doors?" The look in her eyes suggested that she also wanted to add ‘before I could do it first!’.
"You mean that I make him take it up the-"
"MARCELINE!" Bubblegum said. “Missing the point here!”
"Chill out, I was joking. Mostly. Look, what are you on about?"
"I have heard rumors that you...beat Finn when he makes love to you! That you claw him up and bite him and do such cruel things. Marceline, he loves you! How could you?"
Marceline stared blankly. "...Okay, that actually sounds a little bit hot, but I so do not dominate him that way."
Bubblegum relaxed.
"I dominate him in total other ways," Marceline said, grinning fangily. "And he likes it. Finn is my bitch."
Bubblegum's jaw dropped. "You do what."
Marceline grinned and started counting off on her fingers. "Well, firstly, I like to suck his blood when we're in bed or having sex. Or watching TV. Or in bed and not having sex. Or when I'm just bored or want his attention. It was totally his idea, trust me on that! He really likes it when I bite him and drink." She raised her eyebrows suggestively. "Remember when you were all over me like that?"
Bubblegum blushed. "Oh, well, if it's consensual...I suppose I can't argue." She grabbed Marceline. “Also, I demand details! Tell me, I say! Or I will give you such a pinch! In the SOUL.”
Marceline grinned. "Also, I, uh, grab him really hard. 'Cause I'm strong and he's just a guy, he gets bruises. And he also gets bruises down there, if you know where I mean. I'm, like, really strong. I swear, Finn's the only guy I know who could take my lovin'." She paused and added, “Guess Hulk too, maybe, but he’s not my type.”
Bubblegum sputtered. "Oh my..."
Marceline sighed. "And then...after we're, like, done, and he's so exhausted he can barely keep his eyes open, he gives me a little kiss right on the cheek if he can reach me, 'cause I like being big then, and it's usually on the neck if he can't reach...right here!" She indicated a spot on the right side of her neck, her gray cheeks reddening. Her claws traced the spot softly, a small smile gracing her lips. "He lets me do...whatever I can think of. No matter how weird I get, he's all for it. He's so...accommodating, y'know?"
Bubblegum smiled, not sure where this was going. "Oh, yes. He's very sweet."
Marceline licked her lips unknowingly. "Oh, yeah. So sweet. Tastes so good. And he tastes even better when he's under me and wriggling and hugging me and kissing me right on the ear even when I'm biting into him and I swear I can taste his soul and it's so damn-" She stopped, suddenly blushing bright red.
"Please don't stop!" Bubblegum insisted. "I want to know more!"
Marceline gaped at her, and whispered something into her ear.
"...Really?!"
"Oh yeah."
"He...likes having tentacles inserting into his..."
"And his mouth, and everywhere." Marceline looked back and forth and whispered, "One time he let me get super-big and swallow him whole."
Bubblegum blinked. "...Oh?"
"He spent the night in my stomach. It felt so...nice."
“Ah, Bubblegum said, nodding understandingly.
“…You’re not freaked out by that?”
“Bah, I got him into letting girls do that to him!”
“…Hah!” Marceline said. “I knew it!” She raised an eyebrow. "You de-virginated him in stomach mode?" Bubblegum smirked. "Well, 'leastways I can say that I deflowered him for reals."
“Actually, no, that was Susan.”
“Dang it.”
Bubblegum asked, “About these… physical things. Did you...did he ask first?"
Marceline looked embarrassed. "Actually, I kinda had him against the wall and I was kissing him and I...uh, may have initiated things without asking first."
“Ah, been there, done that?” Bubblegum smirked at Marceline. “As you well know, I’m not good at taking no for an answer.”
Marceline smiled nervously. “Yeah. I know.”

At some point, it became clear that someone had overheard Bubblegum and Marceline's girl talk, and certain things became clear.
Soon, just about everyone knew that Finn and Marceline were having sex, and that Finn was most definitely dominated by Marceline in every way, shape and form. (The fact that it was consensual was largely overlooked, as were the snarky comments that this was pretty much inevitable with Finn; even if he was in a relationship with himself he’d still be dominated, the joke ran. More logical thinkers gave themselves a headache trying to figure out that one.)
They knew that Marceline fed on him on a regular basis, and many believed that it was involuntary on Finn's part; many envisioned him crying and begging the love of his life not to hurt him anymore even as she cut off his cries by burying her teeth into the meat of his shoulder and drinking deep. And they didn't know, but they believed that Marceline was, in their words, raping Finn. Sadly, many of the female students who were in a position to chastise Marceline approved of her supposed actions as revenge for the female gender, in some spirit of misandrist cruelty. (Marceline made a point of not talking to those girls much afterwards.) Others were more noble and intended to make Marceline pay for hurting Finn, no doubt due to their own crushes on him and swelled with vengeful thoughts over the fact that she'd molested Finn. Another one of Finn’s closest friends, a fire elemental named Sigyn (nicknamed Flame Princess due to her close association with Bubblegum and thus importance), tried to convince them otherwise, but not having much success, sneakily arranged things so that they were corrected.
By Sigyn’s manipulations, one of the girls saw Marceline and Finn on a date, snuggling on a bench; Finn had been cuddled right into her lap, his chubby body wedged into her larger breasts while he kissed the base of her neck, and she'd giggled and growled such happy feminine growls, hugging him like she was terrified he would fall away and never again come into her grasp. The girl, who was named Jane Foster, had immediately gone home to write a steamy fluff Finnceline fanfic, and reported what she had seen to the 'Finn Protection Coalition', as they called themselves. After much observation, they unhappily came to the conclusion that Finn and Marceline were very much in love, and absolutely not at all in an abusive relationship. (Though it was pretty clear that Finn was the submissive one, and Marceline the dominant one. Some of the girls thought it was kind of hot.)
The rumor got a little nicer after that. Marceline was a little disappointed; it had helped ward off guys hitting on her and she liked excuses to get into fights with people by turning them down as obnoxiously as possible; the guys now had gotten terrified at the thought of a girl who violently ravaged her boyfriend. Now, though, assuming that Finn had been exaggerating, they were trying to hit on her with the assumption that she liked one-night-stands with guys she didn’t even know. Sore over this, Marceline brought this up later on to Finn, Jake, Bubblegum, Lady Rainicorn (an exchange student who was Jake's girlfriend and Bubblegum's good friend, though she was a little too girly for Marceline's favor) and Sigyn during their annual movie night, after the movie but before everyone was about to go to bed. (In the case of the couples, with each other. And not in a sexual way, for the most part.)
Namely, she had said, "Guys, got a problem. Guys are hitting on me again, and thinking they can score me, and I'm tired of beating the crap out of them when they won't take a no. Ideas?"
"Um...perhaps you could make people believe that I am also your partner?" Bubblegum said shyly. "If they think that you're in a threesome, they might get reluctant to be involved."
They stared at her. Finn got a little nosebleed at the thought of having both Marceline and Bubblegum commit sexual acts upon him and each other at the same time. (Again.) "Good idea," Marceline said, looking a little dizzy at the thought. Bubblegum giggled. "But not quite good enough. They might think that I'm promiscuous, and that'll just make things worse."
"Why don't ya tell 'em something that'll freak 'em out?" Jake said. "Tell 'em something true that you and Finn...y'know, do? Something that'll make the guys want to get the hell away from you, Marcie!"
Finn grinned deviously and leaned over. "Marcie, I got an idea." He whispered into her ear.
Her eyes went wide, and she grinned fiendishly. "Oh hell yeah."
"Well, have you decided?" Lady Rainicorn asked.
Marceline told them a large detail about Finn and her sex life. "So I'll tell them that and they'll freak out."
"OH GLOB I DIDN'T NEED TO KNOW THAT," Jake said, foaming at the mouth and falling over.
“Ah, Bubblegum said. “Called it again!” She turned to Sigyn. “Pay up, my lovely understudy!” Sigyn fumed, handing over some credits. (Thankfully made of a material she couldn’t burn with her elemental body.)
Rainicorn gasped. "Oh my," She said faintly. "I thought it would be something small, like you have Finn pleasure you orally when you get emotional or bored or whenever he says a certain letter on the wrong day of the month!"
"Oh yeah, she gets me to do that too," Finn agreed. "We can tell them that too?"
"Sounds fun," Marceline said.
"...If I didn't know that this was totally consensual and likely initiated on Finn's part," Bubblegum finally said. "I would tell Susan at once so that she could pummel you in righteous retribution!"
"Oh, she knows," Finn said dismissively. "Marcie makes me, like...really loud, and Susan came to see what the noise was. She thought it was cute, and we had to stop her from taking pictures."
"...Ah," Bubblegum said, looking like she thought that was quite a nice idea and she should have thought of it first.
And so, upon the next day, it came to pass that Marceline, Finn, Jake, Bubblegum and Rainicorn staged a most epic rock concert to attract the attention of their misinformed or malicious peers, and once it was over, there came a mighty cry from the audience.
For, it was plain to see, their peers wished to know the truth of the situation. Others still wished to bed one of the two lovers, or else believed them vastly incompatible and detested one for 'stealing' the other.
Finn had held his hand up high for silence, and gradually did the assembled multitudes cease their frightful clamor, and Marceline and Finn did indeed look at each other, and Finn grasped Marceline's hand tightly, their fingers intertwining and squeezing. Marceline's hair moved of its own accord and wrapped securely around Finn, and her powers of flight enabled her to lift the two of them from the ground and gently come to a stop before the crowd, and Marceline did ask of the multitudes what they wished to know.
And the multitudes did ask, whether the rumors of Marceline's frightfully aggressive dalliances with Finn were true or not, and so Marceline, extending a massive tentacle from her back to wrap around Finn six-fold times, did indeed say, "Yo, I ravage Finn hard and he likes it!"
"Totes," Finn agreed, putting an arm around Marceline's waist and kissing her hand. She did roll her eyes and grinned.
And indeed, there were many gasps of shock. Some cheered. Others fainted. Many stared in shock. Some of the men (and women) glared at the two lovers, others hoping that this made Marceline permissive.
Finn raised a hand. "And there's something else that I'd like all you guys who hit on Marceline to know something she really likes doing to me, and I want you to think about that happening to you." He waited for his due silence, took a gentle hold of the tentacle wrapped around his body, kissed the wriggling and wet mouth at its tip and proudly said, "Marceline grows tentacles like that and I take them up the butt and I LIKE IT! Whoot!"
And lo, there were many gasps of shock. All the men who had previously propositioned Marceline clutched their backsides in terror and fled at once. Many others fainted.
Marceline tugged Finn up and kissed him on the lips, wet and warm and clinging so tightly to him that her body may well have absorbed him to keep him even closer and sheltered forever. She sprouted more tentacles and wrapped them around Finn, bringing him ever closer to her, and the two of them did make out in public. Right in front of all the mistaken hopefuls.
"As you can see," Bubblegum said pleasantly. "My friends Marceline and Finn are both quite, as you might say, 'kinky'."
With that line, from the ever-so demure and sweet and proper Bonnibel Bubblegum, many rightfully declared it a most rocking concert. And quite a few men with tentacle monster girlfriends cheered, feeling vindicated. Yo.
