“I can’t believe I’m wearing this.”
“Your own idea backfired at you,” Jean snorted as Eren walked out of his room in a full sexy bunny costume. He didn’t even try to keep in his enjoyment and fell into a whole laughing fit while Eren tried to find a coat long enough so people wouldn’t think he was some type of hooker when they’d walk to the costume party.
Eren grumbled, “Since when are you even decent at Overwatch?” They had placed a bet, five games, the loser had to embarrass himself by wearing one of those slutty, pin up bunny costumes with huge ears to Hanji’s costume party on Friday. Meanwhile the other could just go as Batman.
“Since Armin taught me,” Jean said and Eren had to roll his eyes.
Armin, their mutual friend and the one who introduced them to Hanji, had been obviously flirting with Jean. And Jean cockily flirted back, but neither of them had the actual guts to make a move. “Just fucking date already.”
“Wha- me and Armin? You’re joking,” Jean feigned offense and Eren slapped him on his bicep.
“You better make a fucking move tonight or I’m telling.”
“So I take the attention away from your ass cheeks hanging out? Haha- Auw!”
Eren’s palm connected to the back of his roommate’s head as he glared at him. “Let’s just go and get this over with.”
At a quarter past eleven, they arrived at the party and Hanji eagerly opened the door to their apartment. Hanji was a chipper brunet, always acting like they were high on crack and tonight was no different.
“Welcome boys,” they slurred. The roommates already felt the vibrations of the music inside their chests and a wave of alcohol and weed hit them as Hanji leaned against the doorframe. “you’re smoking hot tonight.”
“Eren!” Armin wriggled his way through the dancing crowd, waving his hand enthusiastically, “Oh, and hi, Jean.” Of course, Armin would be dressed as Robin. As if they could be any more obvious.
Jean nodded and Eren waved back in response, shaking his head.
“Hanji, I think Levi needs your help.” Armin nudged their side with his elbow, “He’s about to make two girls cry.”
“Ugh, Leviiii.”
With that, Hanji disappeared back into the crowd and Armin showed them where they could hang their coats.
“Looks like Jean won, huh?” Armin said, trying to keep his snorts and giggles under control as Eren fumbled with the hem of his coat.
“‘S your fault. Look where your stupid crush got me.” Glaring, Eren finally got rid of the article of clothing after taking a long breath. No one would even bat an eye at him right now, he definitely wasn’t the only slutty something at this party. Fishnets also weren’t as comfortable as they looked and he was pretty sure half of the back of his costume had disappeared between his ass cheeks.
Armin chuckled, “Well, you look good. Maybe you’ll also... you know.”
“You can say “get laid” Ar,” Eren huffed, smirking when his best friend’s face got as red as a tomato. “What? You’re saying you’re not going on that horse cock tonight? Hahaha!”
“I swear to God, Eren,” Armin shushed him, “stop calling it a horse cock, I’m not a freak.”
Eren pressed his lips firmly together, trying to keep himself from bursting out laughing. “Right.” Armin wasn’t exactly the most vanilla person, he was in fact the reason why Eren had discovered some of his own kinks. Not together, no, no, they’d never. But Ar’s browsing history had revealed some of his own weird fetishes and that was how Eren actually found out there was this thing called ‘knotting’. Very sci-fi but hey, Armin couldn’t kinkshame him when he was into even weirder shit than he was.
All flustered, Armin dragged him through the dancing crowd till they found their usual group of friends. Mikasa was wearing a Marceline of Adventure Time costume while her girlfriend, Annie, a Princess Bubblegum one; not looking entirely happy about it. It was cute though, cuter than the Batman and Robin Jean and Armin were trying to pull off while still convincing everyone there was nothing going on between them. Did they really think they were all blind?
Mikasa nodded at where Jean and Armin stood and Eren turned his head to see Horseface filling up Ar’s cup. Idiots, he thought before Annie couldn’t suppress the urge to comment on his outfit any longer. “Isn’t it a little too early for Easter?”
“That pink really evens out your bitterness, Annie.”
“Oeh-oh! What a burn.”
“Okay, easy you two,” Mikasa interrupted them for the millionth time. “Eren, go socialize with my cousin, he also lost a bet.”
Eren followed her stare and his eyes landed on a shirtless raven, angrily sipping on his cup. “Don’t mind if I do.” Did he seriously say that out loud?
“Gross,” Annie scrunched up her nose and Mikasa shook her head.
“Please don’t get it on with my cousin, Eren.”
“Why? Is he gay?” Eren looked at her expectantly with a wicked grin. Not caring to wait for her answer, he straightened his back and made sure to sway his hips a little as he strolled towards the shirtless man. Luckily his heels weren’t too high or he would’ve probably made a fool out of himself already. Please be gay, please be gay, please be gay.
“Oh, yes, he’s definitely not straight,” he mumbled to himself as he saw the raven’s eyes raking over his body while smirking with a raised brow. This meant he could go for his usual strategy; teasing, teasing and some more teasing.
Instead of walking straight at him, he went for a detour and grabbed himself some punch, making sure to stick out his butt as he filled his red cup with the green, witchy liquid. He looked over his shoulder, sending the raven a flirty grin before he turned on his heels and leaned against the nearest wall. He took small gulps of his drink, which actually wasn’t bad at all, kudos to Hanji taking extra bartending classes.
The raven still hadn’t moved from his spot, so Eren went to phase two. He side-eyed Mikasa’s cousin and while their eyes locked he seductively bit his lip as he ran a hand through his chocolate brown locks. Fucking finally. The raven walked towards him and while Eren was surprised by his short stature, he sure didn’t mind the perfect set of abs and scowl on his face. Emotional unavailability, count him in.
“So, what are you supposed to be?” Eren said while lowering his cup, not hiding the fact that he was eyeing him up and down like a piece of meat.
Rolling his eyes, the raven pointed at Hanji who was currently doing the limbo. “A werewolf, Hanji’s fault.”
“Where are your tail and ears then…?”
“Levi,” and he shook his head, “I left them at home. Plus, I’m supposed to be Jacob from that Twilight bullshit.”
“Ah, quality literature,” Eren nodded, chuckling under his breath before he took another sip of his drink. “All he did was walk around shirtless anyway and you’re certainly pulling it off.”
Levi scoffed and raised one of his brows, “I would almost think you’re hitting on me…?”
“Eren,” he smiled, “and so what if I am?”
“I’m not complaining,” Levi said and he took the brunet’s drink out of his hand, the brief skin to skin contact making the tips of Eren’s ears burn, and downed it in one go. “So, Eren.”
Clearing his throat, Eren tried to keep his composure as Levi sent him a toothy grin, he was gonna eat him alive wasn’t he? “Hmm?”
“I happen to like bunnies, so how about we go to my place?” The raven said and stretched an arm to touch Eren’s waist, gently digging his fingers into the soft skin. “Only to see my tail and ears of course.”
Gulping, Eren’s mouth went dry and he enthusiastically nodded his head as he felt the heat spread through his body and straight to his crotch. Embarrassing.
Within a matter of minutes, he found himself in the passenger seat of Levi’s car and the raven fastened his seat belt for him, whispering in his ear to behave if he wanted him to be nice. In all honesty, the thought of Levi fucking him roughly stirred him up more, making his cock strain against the confinements of his costume.
“Now be a good little bunny and sit still,” Levi smirked as he hovered over him before dipping down and hungrily clashing their lips together. Pants and moans spilled from the boy’s lips and he rutted his hips against Levi’s hand palming his cock. Eren whined in protest when the raven quickly pulled away before he slid in the driver’s seat. “Better not distract me while driving if you want to come tonight.”
Eren was almost certain he heard Levi purr when he wrung his hands together to keep them occupied and a shot of arousal slid up his spine. He really was gonna have him for dinner and nothing excited the brunet more.
With his legs wrapped around Levi’s waist, Eren didn’t pay any attention to where he actually was when he was slammed against the nearest wall. Levi’s tongue swiped roughly over Eren’s bottom lip and the raven ravished his mouth as he clawed at his clothes.
A surprised gasp spilled past the boy’s lips when Levi ripped his clothes with his nails and left a trail of shreds behind them as he was being carried down the hall to what he presumed was Levi’s bedroom. He was thrown on the bed and within seconds Levi hovered over him and pinned his hands above his head. “Little rabbit fell into my trap.”
Eren never thought he’d be into dirty talk, let alone roleplay, but with the pure animalistic lust Levi was treating him, he couldn’t help but get even more turned on. “Aren’t you going to be nice to me?” Eren bit his lip and Levi’s eyes went from soft grey to vibrant silver at his words.
“Not in the slightest,” Levi sent Eren another toothy grin and a wave of arousal coursed through Eren’s body at the sight. “You have a thing for my teeth?”
Pressing his lips firmly together and keeping himself from making embarrassing noises as he saw Levi swiping his tongue over the sharp edge of his canine, Eren nodded his head and shuddered under his hold.
“You won’t be able to keep quiet once I start having my fun with you, little rabbit,” Levi purred in his ear, rutting his hips so the fabric of his jeans slid roughly over Eren’s pink cock. Leaning down, he bit and sucked on one of Eren’s pierced nipples, rolling the bud between his teeth until the brunet was gasping and thrusting his hips up. “Sensitive? How cute.”
With every action and word Levi gave him, Eren felt his mouth go dryer and dryer and his cock grow impossibly harder. Pearly fluid leaked freely on his stomach, leaving a slick mess all over his chest as Levi hooked his hands under the back of Eren’s knees and pushed forward.
High pitched whimpers and moans spilled past Eren’s lips every time Levi darted out his tongue to lap over his sensitive hole. “L-Levi…” His voice came out shaking and broken as the raven wriggled his tongue past the tight ring of muscle and started thrusting it ever so slowly. Eren wasn’t going to last long.
As Levi bit into the round globe of Eren’s ass, the boy yelped and quickly succumbed under his touch as Levi slid one finger in slowly. He hummed at the tight heat with a smirk before planting another bitemark on the tanned skin. He added his tongue to the mess, alternating between pushing it deep into his ass as he hooked two fingers to spread his hole, and biting down onto his cheeks, close to breaking the skin.
With an angled thrust of Levi’s fingers, Eren tensed and cried out as thick ropes of come streaked over his red collarbones. His chest heaved, cock twitching as Levi milked his prostate dry and kept going until it left the boy completely shaking and blabbering, “L-Levi, I- I already came.”
“I know,” Levi said flatly, lapping over his hole again and angling his fingers, abusing the sensitive bundle of nerves inside Eren’s body until he started begging for him to stop. “Stop? I’m not even nearly done with you.”
Eren’s eyes blew wide at the words, cock growing hard again under the rough treatment of Levi’s tongue swiping over the seam of his balls and dipping into the slit. “I… can’t.”
“You’re a brave little human, you can take it,” Levi smirked as he shoved his nose into the neatly trimmed hairs at the base of Eren’s dick, taking in a deep breath. The action left Eren lost for words as the raven continued and unbuttoned his jeans to let his cock spring free.
It was nothing like Eren had ever seen in real life; Levi’s cock was slightly ribbed, thicker at the base and his cockhead had a pinkishly red sheen to it, just like the dildos he had seen on pornhub and both excitement and fear took over his body. He swallowed thickly, not knowing exactly what to say or do as the raven crawled closer and leaned down to leave a sloppy kiss just below his ear, “Never seen a real werewolf? Adorable.”
Eren’s world flipped upside down as he was pushed down onto his stomach, ass sticking up in the air. He immediately moaned at being so deliciously manhandled, previous worries left forgotten as Levi spread his cheeks and poured a decent amount of lube onto the crevice of his ass. He didn’t care at this point, he wanted to get fucked by Levi and his werewolf dick. Would he also have a knot?
With a slap on his ass, Eren yelped and looked back over his shoulder, blush turning crimson as Levi spanked him again. He was really hitting all of his kinks tonight and he didn’t even realize it.
“Stop thinking, brat,” Levi said as his palm connected to Eren’s ass cheek again, leaving a stinging burn in its wake before he slid three lubed up fingers inside the brunet. “I can smell you’re distracted, come back to me. All of you.”
Eren moaned loudly into the pillow as Levi grabbed his hips and buried his entire length inside of him in one smooth motion. The brunet felt every ridge and bump stroking across his walls with bruising force, clamping down on the thick cock. He got a well deserved minute to get used to his length and girth before the werewolf increased his pace slowly.
He felt everything, the claws digging into his hips, Levi’s cock moving in and out of his willing hole, his hot breath against his spine and his own cock roughly rubbing over the covers. Everything was too much and yet he wanted, craved more of Levi. An insatiable hunger he had never experienced before overrode all logical thought and he rocked his hips backward against Levi’s.
The sound of skin slapping on skin filled the room as Levi started moving with bruising force, letting the animal inside of him take over as the little human beneath him moved and moaned so willingly. “Uncover your mouth, let me hear your pretty noises, my brave rabbit.”
Eren titled his head slightly to the side, letting the werewolf’s ears pick up on the soft pants and moans he made as he buried himself deep inside his ass.
“Prepare yourself, boy.” Levi snarled, angling his hips to slam precisely against his prostate, turning Eren into a drooling, blabbering mess as the werewolf fucked him roughly.
Eren whined in overstimulation as his prostate was abused to the point his entire body trembled and tears rolled down his cheeks, feeling too good for words. He gasped at the sensation of Levi’s cock growing bigger, stretching his hole wider with each thrust.
With a deep rumble inside his chest, Levi launched forward and bit down on Eren’s nape, drawing blood, as he slammed his cock deep inside Eren. Knot growing to its full size, stretching the human impossibly wide, he came in the boy’s ass, painting his insides with thick ropes of his come.
He felt beyond full, cum and knot filling him up to the brim and when Levi’s teeth sank into his flesh, his second release crashed over him. He came untouched, cock twitching and spurting his come on his stomach and the covers. A sleepy smile spread across his face when Levi held his hips up as his body lost its final strength.
Completely satisfied, Levi planted a kiss on the back of Eren’s neck, whispering sweet praises in his ear as sleep washed over the little human. “My sweet Eren.”
It was dawn when Eren awoke, the sun peeking through the curtains. He was tucked in bed, clean, and with a pair of pajama pants on. The smell of tea and something sweet filling up his nostrils.
It took him a moment to recollect his thoughts, the vivid images of last night flashing before his eyes. As he stood, the heavy pain in his hips along with the purple bruises and red marks all over his body served as another reminder that all of it had been indeed, very real.
With a droopy grin, he got up from the bed and shuffled towards the source of the sweet, hearty smell, finding Levi sitting on one of the chairs in nothing but sweatpants and two sets of pancakes in front of him. Had he cooked breakfast?
Levi’s eyes shot up once Eren peaked his head past the doorframe and he instantly jumped up and wrapped his arms around the brunet’s waist. He held him gently, a purr rumbling in his chest as he nuzzled his nose in his human’s neck. “Morning.”
Overwhelmed by the sudden affection, Eren stammered, “Morning.” Levi was so gentle with him, a complete 180 compared to last night, but it honestly felt right? As if their bodies remembered each other from before and were finally reunited. Eren laughed under his breath, how silly of him.
