And I Will Fuck You (Like Nothing Matters)

so it started when i saw a tiktok edit for mr lawrence and i was like oh he's kinda cute, thats nice and then i scrolled through the comments and one of them said "raw and the voice stays on" and at first i was like haha funni and then oh and then haven't stopped thinking about that since so i made my edits and now we're at this point. hooray!title is from the last dinner party's nothing matters.

so uhhh this is charleston (human!plankton) x reader. no beta! i wrote this while im medded up and half delusional with a 37.5°c fever, so yay!

contents: 18+, smut, age gap (reader is in their mid to late twenties), cheating, and inappropriate relationship between an employer and employee. angst if you squint. ⚠️minors dni

You don’t know how you ended up here – with your boss grinding his dick against your clothed heat and your combined, hushed moans filling your cramped studio apartment.

What started out as you simply offering a bottle of beer to Charleston after a particularly rough day had now led to this very predicament you two found yourself in – with you on top of your boss and your murphy bed quietly creaking against the wooden floor.

Sure he's not like, model handsome, but for some reason, you can never tear your eyes away from him when he doesn’t know you’re looking. He’s old enough to be your father too, but he's not, and you're way past the age of consent, so really, who's counting?

You always find yourself staring as he tinkered around his tools and gadgets, eyebrows furrowed in concentration as Karen provides calculations and adjustments while you man (read: keep a lookout) the always empty Sham Buckets. And that's when you're not serving as his on the ground minion.

He's handsome in a geeky way, though, like one of those 80s movie nerds that grew up, and combined with his determination and brains, it's only a matter of time before you realize how very much you're into that.

It felt wrong to have your boss - your older, married boss - letting you get off like this (or was it actually him getting off as you let him rut against you, naked, save for your underwear?). But it felt good. The added thrill of infidelity sends a shiver down your spine every time he mutters, "This is wrong," and "We shouldn't," against the valley of your breasts and his hands roam across your body.

But if you were being completely honest with yourself, you couldn't care less.

After all, it's not like he was married to a real person, right?

Sure, the Karen v.05 AI is progressing really quickly (you wanted to ask why he didn't just focus on AI and tech development, he would have made enough cash to buy the Trusty Slabs a hundred times over), and sure, she can come up with world domination plans A to Z in a nanosecond that you know will succeed, but there are things that even she can't do.

You doubt her alloy appendages would be warm and soft enough to coax out his breathy, whiny moans like this.

Any semblance of concern towards Karen fades as Charleston moves, one hand reaching down, and pushing your panties slightly to the side and starts to rub your clit with his thumb, the other palming one of your tits, alternating between brushing and rolling his fingers at your already stiff nipples and giving it a gentle squeeze.

You couldn't help letting out a moan, and what's worse than an evil genius is his ego. "You like that?" Charleston asks in a deep, smug voice, as if he hadn't been desperately whining just a few seconds ago. “You’re dripping,” He adds, middle finger pushing inside your sweet, wet cunt.

"More," You moan, pushing down and grinding on his finger, draping your arms over his shoulders for balance. Then, you start playing with the nape of his neck. An excuse for you to hold him as close as possible. "J-just the tip, you c-can put in just the tip. You don't even have to be naked,"

His eyes widen a bit, and you see him swallow a lump in his throat. You agreed to letting him keep most of his clothes on, only really removing his balaclava and his eye patch.

He mentioned it's something about not letting this go too far. Something about still keeping boundaries.

"I-insatiable, aren't we?" He croons, like he isn't two fingers and knuckle-deep inside of you; like he himself hasn't been leaking precum.

"I've wanted this for such a long time," you whisper, moving your lips closer to his ear before giving the earlobe a gentle, tugging bite; your fingers carding through his hair. "I've wanted you for such a long time, boss,"

He groans, whether out of guilt or pleasure, you don't know. You don't care to find out.

"I want you," You whisper again, running your hands from his still clothed chest down to where his pants have been unzipped.

You're sitting on him with your legs on his either side in a way that pressed your cunt directly against his shaft, making every purposeful thrust just fucking delicious. Your crotch is warm and slick, and your core is practically pulsing to have something inside it as once again, you ground your clit on his cock. "You know that, don't you?"

He responds with another breathless moan. His hands flying down your hips, griping it tightly, fingers digging in to hold you still. "You don't know what you're asking for, (Y/N)," He warns, voice dark and gritty.

It's supposed to be threatening, but all it does is make your pussy throb.

"Don't I?" You counter, ever the obstinate minion.

Charleston gives you a second-long glare before grabbing your chin and pulling your face to his, thin lips locking onto yours in a warm, wet kiss.

While you appreciate the enthusiasm, he's obviously out of practice, with the way his lips are moving without rhythm against yours, but you were kind enough to guide him through the process.

It takes you half a minute after he pulls away to realize he's repositioned the two of you, with you laying on your back, your panties already dangling down on one ankle, and him, still clothed with just his pants unzipped but equally as flushed and hair disheveled, hovering over you.

He fully frees himself from his boxers, running the tip through the warm wetness of your folds. It’s been a while since he’d been with someone else - couple of hookups during college, and only having been with K - her (it doesn't feel right even thinking about her name at the moment) ever since, and he belatedly realizes that he's missed this feeling.

And you are such a pretty young thing too, aren't you? Smart and sardonic but always so, so loyal to him, despite the tiny little mishaps in his plans. You were always there, ready with the getaway car.

And wasn't it you prepositioned him first?

He'd be damned if he doesn't savor it. Doesn't savor you.

Your eyes nearly roll back into your head as he slowly eases the tip in. He's doing this on purpose, you note, as he's being unnecessarily patient as he watches your eyes flutter close and your chest heave as you sucked in breaths.

“P-please,” You whine, eager for friction against your clit to satiate your lust.

You watched his brows knit together as Charleston starts with shallow thrusts. He was about half way in when he feels you clenching down impossibly tightly.

"Damn," He muses. "This tight and wet for me already?"

"S-shut up and start m-moving," You answer back, although it did not come out the way you intended as it escaped your lips as a desperate whine.

He glares at you again, but he doesn't mean it. Not really. You're so, so warm and tight around him that it's taking all of his self control not to finish right away. You meet his eyes and hold his gaze, biting your swolen, lower lip as you tried to silence a moan as he pushes deeper inside you. The sight of it, of you is just...

Something inside of him snapped, like a switch that he knew could never be turned off now that it's been flipped.

Before you could mouth off, and knowing he can't hold on much longer either, he picks up the pace, angling his cock perfectly that he was hitting your clit with every thrust, and you could swear you were seeing stars.

But that's not enough for him, not just yet. Not until you're completely undone under him.

Charleston moves to lean closer, latching his mouth around your nipple, flicking with his tongue and taking the hardened bud between his teeth, tugging slightly. You bring up one hand to your mouth and bite down on your knuckle to stop yourself from getting noise complaints.

He lets out a slow laugh at the sight of you trying to muffle the sounds that try to escape your throat. "No, (Y/N), not like that," He says as he pulls your hand away. "Like this," He adds, capturing your lips and swallowing down your moans. You notice that he's copying the way you kissed him earlier.

"I'm close," He mutters against your lips as he breaks the kiss off. "I'm so close, (Y/N),"

"M-me too... I'm - so close, Charleston, p-please," you moan as quietly as you can, and the desperation on your face (as well as his) is enough to make him snap his hips harder, chasing both your peaks, your eyes screwing shut at the sudden intensity and your mouth falling open as you feel yourself cum on his cock, screaming in a silent orgasm as he groans against your neck. You feel him shoot ropes of cum inside you, filling you up.

Just how long has this man been backed up? Didn't he do freaky sex stuff with his robot wife?

He stayed inside you for a couple of minutes as we went soft. Your apartment quiet, save for your combined heavy breathing.

But the weight of the guilt starts to come creeping back. You avoided looking at him, despite his cum still inside you. Looking at your him post-coitus would feel a little too intimate, because you know he's married. Because you know he loves her, despite... whatever just happened.

The atmosphere shifts.

He pulls out, but neither of you speak, though you both know what’s lingering heavily in the air. You tell yourself that all you care about is getting what you wanted, about getting off and fucking him, and you got it, didn't you?

Right now, though, all you want for him is to leave, and treat you like he's always did tomorrow when you show up for work.

So you didn't stop yourself from speaking first, breaking the already tense silence between the two of you. Your throat scratchy and voice slightly hoarse as you pointed out where the bathroom is, adding that there's a clean towel he can use. You even told him he can borrow one of your bigger pajamas to wear as he heads out, since the one he has on is obviously soiled. You tell him he can leave it here too, and you'll throw it in your washing machine and return it back to him in a few days.

Charleston gives you an odd look, and opens his mouth as if he's gonna say something, but thought better of it. He nods wordlessly and walks to your bathroom, closing the door.

You feel yourself about to drift off.

You'll let the guilt gnaw and fester inside you later. Hell, maybe you'll hit the town and hangout with Jimbob and Rick and Andie or any of your other friends later. Or maybe you'll stay in and order takeouts as you cry all night.

Right now, though -

Right now, all you wanted was a nap.

So you yell out that he can just lock the door on his way out as you shifted and moved around in your bed and throw your blanket above your head.

You'll clean up and change your sheets later.

Your SpongeBob yandere headacanons has inspired into getting more yandere stuff and saw some ppl posting their headcanon so I wanted to post mine that are abt plankton

•I see plankton as kind of an manipulative yandere, he treats his darling like how he treats the secret formula in a way where he just constantly thinks about them, sometimes they just ignore what anyone is saying to him just to think about how he’ll win his darling’s heart with some kind of ridiculous

•And the darling would be kind of aware of this since plankton doesn’t exactly hide it.. uncomfortably aware of it

•plankton indulges in a whole lot of stalking, he mainly stalks them from the restraunt’s massive telescope or some kind of weird robot that has a camera in it, he just has the weirdest ways to make sure he can pay attention to his darling

•I think the darling probably has a lot of friends and plankton would be super jealous easily considering his hate for other people (or other fishes I guess?) and would constantly complain about them either to himself or to Karen, he usually complains about one of their friends not actually being good enough for their darling and how they don’t rlly need them all that much

•It’s kind of gone to a point where the darling hides in the krusty krab a lot since the krusty crew usually protects them especially SpongeBob and Mr krabs, which plankton isn’t exactly pleased about and sees it as krabs trying to steal their love from them considering him and krab’s history together

•I definitely don’t think squidward rlly cares all that much unlike with SpongeBob and krabs who go out of there way to make sure the reader is safe from plankton

•But still he’s very hard to escape from, He always finds a way to see you, and it’s very hard to know if he’s watching you or not, he could be in a cookie or in a Krabby patty or a bug on your shoulder who knows if he wanted to he could make a weird disguise or robot to keep tabs on you and there’s a chance you wouldn’t even know it’s there

•he also does indulge in kidnapping the reader as well, either from their home or from the krusty krab, you could be just casually be eating a krabby patty or sitting at home doing work and then out of nowhere you’re suddenly being kidnapped by a tiny green mad organism and sometimes his computer wife if she feels like actually helping

•he’s definitely a tad delusional honestly, he cannot grasp the idea of his darling not actually liking him or trying to avoid or just generally not fitting his ideal version of them in his head, And just blamed his darling not being around him on Mr krabs or any of the reader’s friends

•I definitely think in instances where plankton’s schemes work in his favor like in the SpongeBob square movie where he does genuinely take over the world he constantly keeps you by his side while being mind controlled by the hats, in-fact you we’re probably the first to be mind controlled, because you can’t exactly say no to his love when you’re being mind controlled

•he also constantly tries to impress his darling a lot mainly by flaunting his plans or showing himself off when he’s doing one of his schemes, tho telling the reader his plans usually doesn’t work out for him very well since the reader ends up telling Mr krabs ahead of time what plankton is planning today

I’m sorry if not a lot of these make a whole lot of sense I get nervous about writing sometimes and I’m mainly trying to improve a lot since English is not my first language, and also sorry for having a word choice like plankton 😭 I just really like the idea of him being a yandere considering his personality

YES! Yandere Plankton finally exists! It is a glorious day, and I thank you!
