He's wrecking so very badly, Send help

Donghyun was going about his day perfectly fine until he set his foot over the kitchen threshold, and the first trickle of a moan came in from the adjacent walls. He immediately recognized the very specific, very airy octave of your voice.

The panting, the gasps, the very scheduled short exhales that ran through the conduit of your throat. He tries to stare at the fish through the aquatic looking glass in peace, hoping to alleviate the sound of your moaning that continues to bleed from the insulation in the thin apartment walls.

He finds himself quite vexed which is incredibly rare for nonchalant, unbothered Donghyun. For the longest time he thought he was broken. Never being able to forge any special connection with anyone that didn't sport a fin or gills.

When he met you though…

“No-” Donghyun shakes his head, hoping the movement might wash away all the mental images threatening to implode his head in. The memory of your passionate, albeit short history as neighbourly fuckbuddies threatens to rear its ugly head… Donghyun tries to distract himself and these new and complicated feelings of jealousy (definitely jealousy) by focusing on the underwater scavengers swimming blissfully about their makeshift prison. Every time he tries, you moan a particularly loud ‘F-Fuck’, and now he's hard and damnit, he can't focus on the fish. Your moans ascend to a higher octave, an octave that gives him unfortunate flashbacks of the night he first met you.

Then, it had been him who drew those sounds from your throat.

Donghyun didn't always believe in fate but there was no other way to describe that evening. You would have both continued on as oblivious neighbours were it not for your roommate accidentally locking you out of your apartment for the 100th time. Donghyun reminisces on how he found you seated outside your door. A tipsy, blubbering mess.

Thinking that he wouldn't like to go to hell, Donghyun decided to pick you up from off the floor after inquiring whether you were comfortable with fish (he wouldn't like to invite any stranger into his apartment that was even a little bit hostile towards the fish) and thereafter, lumbered you over the threshold.

You had been mumbling about a variety of topics that Donghyun would kill to have you relay back to him right now, but one after the other, the topics dwindled into you enquiring about more alcohol. Claiming that you couldn't wait for your roommate on an empty stomach.

"Food," he had said in a deep and dreary monotonous voice, "If you're hungry, you should eat some food,"

"Food is boring," you whined.

"It really is," he found himself agreeing almost automatically.

"I have an even better idea," it was then, that you uncovered three bottles of soju from your purse with a conspiratorial drunken smirk on your face. The evening had inevitably ended with the both of you getting inebriated under the dim blue lights shining from his tank. And under those very same lights, while Donghyun droned on about the cardiovascular system of freshwater fish, your lips met his in a sloppy, unceremonious kiss.

He did not know this when you kissed him, but he would soon become obsessed with you. That could be the only thing he could describe this as.

"Ugh, how can you stand to listen to the sounds of our neighbors fucking," Donghyun is pulled from his reverie by Sungho who strolls into the kitchen. His roommate's messy head of hair is tipped back in distaste at the scandalous sounds emanating from the next door apartment.

"Neighbour." Donghyun says, "We only have one and she lives alone," Donghyun appears seemingly unperturbed by the sound of your moaning. If not for the subtle whitening of his knuckles against the tabletop upon which his fish tank sat, anyone could've sworn he didn't feel a thing.

"I don't even wanna know how you know that-" Sungho begins to rummage for his pots and pans, all while Donghyun drones on.

"I spoke to her. Once." Donghyun says "Only once. We had sex."

A clamouring of metallic utensils ring throughout the small apartment as Sungho whips his head around to stare at the monotonous boy with amazement.

"Is there anything you ever think of keeping to yourself?"

Donghyun ignores his statement, "But now she's doing that..." he says, in that same difficult-to-interpret, monotonous voice. Donghyun gestures to the blank wall that divided the apartments, "With whoever that is..." A tense silence prolongs before Donghyun; quite suddenly, stands up. "Should I go over there?"

Sungho's shakes his head as he says, "You should absolutely not go over there-"

"I think I should go over there," He's already backing out of his chair, bidding the fish goodbye.

"Donghyun, I will disown you as a member of this apartment if you go over there-"

"It'll be quick,"

"Donghyun."

He's not sure why he'd wanna torture himself, nor did he care to know. All Donghyun is concerned with is the sound of your pleasure being caused by someone else. Someone that isn't him. And so he thinks nothing of it as he drifts towards your door stationed right next to his and he knocks.

There is a bump of furniture and a swear until you're racking the door open, the very vision of pre-orgasm jitters. Donghyun observes you in this very familiar glow. Your eyes are wide and wayward. Your hands are fumbling with the belt of your robe and there's a slight tremor moving through your entire form. You may appear disheveled to any other passerby but to him, you were the very object of his desires.

When your eyes land on him, your shoulders deflate in an unimpressed stance. You are just in the middle of scolding him lightly as you say, “No, Donghyun, I don't wanna volunteer to clean the beach with yo-”

You're not able to finish your sentence because he's rushed towards you in an instant, capturing your lips against the soft plush pillows of his own, and your words die right then and there. He cradles your face with both hands and you yelp in shock as he nips at your bottom lip, all while pushing himself into your apartment.

“I didnt-” he whispers, unable to tear his lips fully away from yours, “I didn't come here for that-”

He mindlessly kicks off his shoes at the doorway which proves to be exceedingly difficult, given the fact that he's hellbent on keeping your lips attached.

“D-Donghyun-” you try to mumble but his lanky fingers curl into your cheeks, forcefully keeping you there. He kisses your roughly. So roughly it nearly knocks out every single sliver of sensibilities you had left. His tongue is long and eager as it drift over the outside of your lips and on the inside, seemingly wanting to eat you whole.

“Donghyun-”

“What-” he whines, stomping his socks-clad feet against the wooden floorboards. “Why are you ruining the moment?” He dips his head down to try and capture your lips once more, but now that you've escaped his forcefield, you've sobered up a bit.

“Why are you, in my apartment?!” It's the only thing you manage to say, with your hand pressed firmly against his sternum. You're both panting loudly. Both caught in a very dangerous state.

Donghyun swallows thickly.

For some reason, you drop your hand to grip your robe tighter, as if not trusting yourself to keep it on in his presence. It is a baby pink robe that Donghyun finds surprisingly erotic. With the scent of sex hanging in your living room, it was difficult not to find anything erotic. He sees you watching him with wide, baggy eyes. Those were erotic too.

“Donghyun.” You begin, with a voice lowered in warning. “Why are you here?”

He swallows once again before straightening his spine and running a hand through his mid length brown locks. He fights to regain some sense of control as he racks his brain for all every plausible excuse.

“So-” he clears his throat, “I'm a father of fish,”

“Famously,” you mock with the roll of the eye. He has to stop himself from kissing you again, choosing to lift his left hand to push down his right twisting in a fist at his side.

“And I’m thinking of adopting a few cichlids.”

“That doesn't explain why you kissed me?” Instead of answering your question, Donghyun ventures to stroll towards your couch as he says, “And the males, famously, cannot be put in the same tank as other aquatic fish. They're unnecessarily hostile and territorial,” he lowers himself fo your couch, “Kinda like you are right now,”

Before you shout at him, he continues

“And I was wondering if you have a spare fish tank around here by any chance.” he nods his head, throughly please with his awful lying skills, “Thats why I'm here.” Donghyun’s eyes are still coasting around your apartment, waiting to hear the voice of the male that was making you moan so loud just a second ago.

“You expect me to just have a fish tank?” You deadpan, “By chance?”

“I don't think my question was so difficult to understand.” Donghyun watches you with a cocky open mouth smirk as he pushes his back against your couch, “This conversation would've been wrapped up so easily if you just-”

“Well, thanks for the weird nature lecture,” you're charging towards him, robe billowing. He sits up, excited. “And the kiss-”

“We could do that again if you want-”

“But I have to study, Donghyun, and you're distracting me,”

You're latching onto his forearm, hellbent on pulling him off your couch but Donghyun digs his other hand into the seat, letting it act as an anchor, keeping him there.

It is then, that your hot pink vibrator rolls out from underneath a cushion and right against the side of his hand.

You stop your pulling.

He stops his mumbling protests.

You both stare down at your vibe sitting comfortably against his hand in the dip of the couch.

“I-”

“Studying, huh?” the smugness in his voice is borderline sadistic. Now it's your turn to scan your brain for every possible way you could detangle yourself from this web of embarrassment. “I like this kinda studying-”

“Donghyun-”

“Leehan-”

“Whatever.” You sigh wistfully, “Just, get out, please.”

“So you don't want my help then?” The question rocks you to your core, a core which you unfortunately realise is still soaked and begging for release. You were just on the precipice of diving headfirst into your orgasm when the knock on the door came and you were overflowing with anxiety. Honestly, being bombarded with a kiss from the weird guy next door shouldn't have been as pleasant as it had been, but your needs evidently took priority of your senses.

“H-Help?” Your voice is barely above a whisper, “How?”

“Lemme show you,” he whispers with all the allure of a Disney prince, and the sensuality of a crimson ribbon. He wraps his hand around your forearm; twirling you quite ceremoniously into his lap.

“You must be so needy right now,” He whispers into your ear while he moves at snails pace, to lower your back against the couch, “I promise to be so good. Better than last time-”

“We were drunk,” you say, utterly captivated by Donghyun now peppering kisses along your legs. He makes his slow descent down the hill of your thighs, while everything in him craves to just attach his lips to your clit until you're riding his face dismally.

Donghyun groans then into the open air. “Fuck, I wanna eat you out,” he admits gravely. He lifts his eyes, hoping to relay to you just how badly he wanted this.

“We were drunk then, so let me do a better job now, ‘kay?” Donghyun rubs dizzying circles against your stomach, still very much covered by your robe.

“O-Okay-” You whisper your consent and it completely throws him over the edge. You yelp when Donghyun grabs ahold of your calves, almost immediately fighting your leg over his shoulder as if your weight was nonexistent.

“Don't blame me if I like… cum in my pants or something, alright?” He says, lowering his face to your exposed as he spready your legs wider.

“P-Please just eat me out, Donghyun,” you were asking him to as if you needed him. That thought solidified itself in his stomach and wrenches your panties to the side, immediately attacking your pussy with his puffy lips.

“F-FUCK, LEEHAN- NOT SO FAST-” Your hands fly to his locks. Your mouth hangs open and you watch in disbelief as he hums against your vagina.

“You called me Leehan-”

“You're- so-” A gasp steals itself from your throat as Donghyun sticks his tongue out to lick a thick strip up the length of your pussy, “s-trange.” you say, unable to chase his lips with your hips.

"You're so hot- fuck,” Donghyun immediately shifts onto the floor so he’s kneeling before you. Your cunt weeps for him and he gladly obliges.

“What a leaky little girl,” he whispers, instantly feeling your hips stutter upwards, “You like that? You like it when I call you my leaky fucking girl-”

You're moaning again, and Donghyun can't help but smirk.

“Y-You're such a pretty little slut, you know that?” Donghyun Isn't sure where that came from, but he's rutting into the couch now, at the same pace you're fucking his face and he knows he needs to say it.

“Oh my fucking God- Donghyun!” You're utterly amazed. Amazed because you didn't remember your last time with Donghyun being so visceral. You nearly see stars when he wiggles his tongue against your entrance, begging for entry.

“F-Fuck my face, baby,”

“D-D-” His name is lost in your mouth and you're lost at the sight of him kneeling for you, fucking helplessly against the couch as he kisses your cunt oh so sloppily. You slip into your orgasm with a shallow gasp and Donghyun's eyes flutter closed, smooching your pussy in pure fucking bliss. He's mumbling incoherently info your cunt, telling her soft nothings until his own hips stutter-

“G-God your pussy is so precious,” he whispers, “So fucking precious-”

You're breathing heavily, but Donghyun decides he's not done as he rises from between your legs. Through your half-lidded gaze, you can spy the wet spot against his sweatpants, and yet he still seems driven by lust. That was one thing you did remember from your last encounter. Once you had Leehan revved up, it was nearly impossible to turn him off.

“I wanna fuck you,” he says monotonously while already pulling at the drawstring of his sweatpants, “I wanna fucking merge into you, L-Like a fucking anglerfish-” he lowers himself on top of you, “D'you know that once the males find a suitable female they merge into-”

“Give me five seconds.” You beg, still in the process of catching your breath, "Or fifteen,"
