NINE TO FIVE, FIVE TO NINE Yandere Married Boss x Office Siren Reader

AN: RAHHH. IT'S FINALLY HERE. This took me way longer then it should have but I'm really proud of it. I hope it lives up to the expectations of the 400ish people who liked the original post. This ones filled with shitty people all around.

Every quarter, your company’s HR department sends out an employee satisfaction survey, and every quarter when you reach the “What is your favorite part of working for our company?” question, your answer is the same.

You love the community. Your colleagues are respectful and hardworking; willing to go the extra mile to ensure deadlines are met. You feel as though your work contributes to something larger and that your efforts don’t go unnoticed by your employers. 

Very cute. Very professional. It would be the perfect answer if it wasn’t all bullshit. 

Your coworkers are fine, but not worth a twenty minute commute and shitty benefits. What actually keeps you slugging into work every morning is far less… admirable. It isn’t something you could write on a company survey without consequences, at least.

Your favorite part of your job is bouncing on your boss's cock.

Yes, you know, “shame on you” — but it’s not like you intended to be an office siren. When you applied for the job all you wanted was to make rent. This was your first “adult” job, so in adult fashion, you tried to keep things professional. 

Emphasis on tried.

It's just... how could you work to your fullest when you were spending all day fantasizing about those toned forearms pinning you down? How were you supposed to answer emails when you were busy wondering if he looked better in or out of his suit? Everyday he sat five feet away from you looking so pent-up and fuckable, could you really be blamed for getting distracted? The hit to your productivity was a detriment to the company. You were just being a responsible employee by fixing the issue.

Yes, he’s ten years your senior. Yes, there’s a blaring ethical issue with a boss fucking his secretary. But he’s a man of childrearing age and you’re a fertile young woman; it’s not your fault you have biological urges.

Besides, it’s not like he’s absolved from blame. You certainly don’t force him to lie down on the couch in his office and pull you onto his face. The desire for you to cum on his nose is entirely his own.

“Fuck, Y/N.” his groan vibrates up into your core, pulling the knot in your stomach tight. One rough hand lies at your waist, following your hips as they roll against his mouth. The other works at his perked up cock, lazily tugging up and down as he devours your cunt. “That’s it baby, ride my fuckin’ nose.”

He’s been at it for nearly half your lunch break now, lapping and sucking at your folds in lieu of his actual meal - not that you’re complaining. How could you, when his tongue is so adamant? It flicks through your folds greedily to earn more of your juice, savoring the salty-sweet taste he’s become so addicted to. Every slurp, lap and suck is catered specifically to your preferences.

You've done well with him. When you first took him under your wing he’d never even eaten pussy before, in fact, he’d only ever slept with two women. Not for lack of desire, he told you, he just never had the time or confidence to flirt in his twenties. Before he knew it, time got away from him and he was past the age where hookups are deemed socially acceptable. 

Your heart broke for him. A man as handsome as him shouldn't be having mediocre sex. So you, being the selfless woman you are, offered to help him make up for lost time. 

It only took one blowjob for him to overlook the ethics of the situation.

With a gentle hand, patience, and lots of encouragement, you’ve turned the businessman into a first rate manslut. He fucks and eats pussy like a veteran now and he’s always eager to get more practice, he drags you onto his face nearly every time he calls you into his office.

He’s come a long, long way, your little pet project.

Inadvertently, you thrust your hips forward, grinding your clit against the bridge of his nose. His tongue burrows itself into your hole, and that’s enough to send you over the edge. Your belly goes taut, your thighs clamp around his ears and you bite your lip to stifle your scream as the contractions roll through your body. Each one sets off fireworks. Fizzing and popping like sparklers in your tummy. Mind-numbing, toe-curling, perfection.

He’s an absolute mess when you climb off of his face. Completely blissed out, face dripping with juices and saliva, glistening in the light pouring through the window. The collar of his pristine white dress shirt is drenched and wrinkled, most likely ruined, but he doesn’t seem to care in the slightest. No, his hungry eyes haven't left that cute little mound between your legs.

“Bend over the desk.” he growls, leaving a smack on your ass as you pull yourself up, and despite the sting you can’t help but smile at his confidence. He’s a far cry from the man he was before you got your hands on him.

You decide to reward him with a little show; swaying your hips teasingly as your stilettos click across the floor, obediently laying yourself over the smooth mahogany, keeping a light arch in your back so he has a nice view of your ass. 

You smile coyly at his reddened face, “You coming, Boss?”

His adam's apple bobs and he makes his way over, eyes dark and dilated, cock leaking beads he positions himself between your legs.

“We only have fifteen minutes before my lunch ends,” you purr, “You think that’s enough time to make us both cum?”

"That’s more than enough~" he growls, grabbing a handful of your hair and yanking back so he can purr in your ear, "Do you want my cock in this tight little cunt, Y/N? Do you want me to fill you up?"

You frantically nod, accentuating the act with an exaggerated whimper and needy roll of your hips.

"Beg for it then." he hisses.

If you were in a sadistic mood you might test how long you could make him hold out, but you feel like indulging him today, so you look back at him all teary and doe-eyed. "Please, please, please, Sir. I need your thick cock in my tight little cunt! I can't - Ah! - I can't take it anymore!"

A loud groan tumbles past his lips as he lines himself up, tracing the fat head up and down your slit,  “Slutty thing. That’s alright baby, I’ll give you what you—”

The clink of something falling off his desk interrupts the thought. The object in question rolls a few feet across the wood floor before wobbling in circles and finally lying flat.

His wedding band glitters innocently in the afternoon sun, silently mocking its owner and his mistress.

Ah, the elephant in the room.

Yes, you know he’s married. If the ring wasn’t enough of a tell, the picture of the two of them on his desk is. He's about a decade younger in it, grinning wide as she presses a kiss to his cheek. They took it in France during their honeymoon, he told you. 

You’ve never met his wife, but you can tell from the picture that she’s the quintessential college sweetheart. The type of girl who’s never drank, smoked or had a cavity. The kind of girl you propose too at the park and settle down with in a white picket fence suburban neighborhood. The kind of girl who says “Not tonight, honey.” when you ask to have sex at the end of a stressful day.

In layman's terms, she's boring.

And clearly, she isn’t taking care of him correctly. He was so obviously pent up when you started flirting with him, just a glimpse of your cleavage was all it took to get him rock hard.

Of course it’s morally reprehensible, but you could argue that making him work his dull 9-5 everyday for nothing in return is wrong too. Somebody had to help the guy out. If she wasn’t going to do her job then you’d have to do it for her.

The guilt nearly killed him at first. The day after the first blowjob he dragged you into his office and furiously—or maybe desperately—started pacing up and down the room. Giving you the “We can’t do this. For Christ’s sake Y/N, I’m married.” speech, whether he was lecturing you or himself, you aren’t entirely sure.

Still, you listened patiently as he rambled, and eventually you decided it was best to back off. It was a disappointment for sure but you'd get over it. You were too hot to be meddling in people's marriages anyway. 

At least directly meddling.

You didn’t make any more blatant advances, but you did start wearing dresses and skirts that fell a tad too short to be considered work appropriate. The necklines of your tops started plunging too, showing off as much cleavage as you could without HR getting up your ass. And you suddenly became very clumsy. “Accidentally” dropping things whenever he was around, or leaning over his desk just enough to give him a nice look down your shirt. 

Not even a week later he pulled you into his office, all but begging on his knees for you to fuck him. That was your green card. You aren’t to blame if he’s the one who instigated. So you rode him like a mechanical bull, chest filled with pride as you looked at that stupid picture of him and his wife.

You always get what you want in the end.

Dispite your victory however, his wife remains a thorn in your side. Your boss has gone completely soft staring at that dumb ring, thinking of his dumb wife who probably couldn’t suck a dick to save her life. No wonder he’s cheating, the bitch pisses you off and you’ve never even met her.

Holding back an exasperated sigh, you give his tie a gentle tug. You soften your face as he turns back, gently--teasingly tracing your thumb along his jawline, stopping at his chin to gently tilt it up. And though he obeys the silent command, the shame swimming in his eyes makes your smile waver.

It irks you, for some reason, how upset he is by this. Maybe that’s selfish. Maybe you should have more sympathy, but you can’t push past the desire to keep him for yourself. You may have won, but did you really if his heart is still hers? 

That’s something to address another time. Getting him hard again takes precedence right now, you’re not going to let that bitch get between you and his dick.

You pull yourself off of his desk, grabbing his hand gently. He follows you to the couch—far more hesitantly then you’d like—but he doesn’t complain when you lie him down and climb on top. He never complains when you climb on top. You leave a sweet kiss between his eyebrows and the cute, attention-starved thing burns bright red. Adorable.

“You’re alright.” You caress his stubbled cheek, slowly coaxing him with honey-sweet kisses, like a siren luring a sailor to his doom. “It’s not your fault you have urges, remember? You’re a grown man, it’s not healthy for you to be so pent-up.” 

His throat clicks with a heavy swallow when your hand moves down, gently wrapping around his soft penis, stroking it lightly, teasingly, all while flashing your big, lust-blown eyes and quivering lip. The rod in your hand fills out shamelessly, and like a bad habit, his eyes flick back down to your pretty cunt. You can tell he’s itching to touch, his morality holding on by a thread, but he’ll always fold to you in the end. You, and your torturous little pocket of bliss.

“That’s it baby.” you purr, picking up his trembling hand and placing it over your clit, “Little circles, just like I taught you.” As soon as his hand starts moving he’s putty in your hands again; any remaining penitence completely snuffed out. He’s hypnotized. Pussy-whipped. Rubbing your little pearl with rough pads, working it like a joystick and groaning licentiously as you trace the head of his cock up and down your folds. You line yourself up, leaning forward so you’re hovering just a few centimeters away from his face, close enough to feel his hot breath on your lips.

“We both know she can’t give you what you need. But I can. I’ll make you feel so good~” you purr, letting one hand find it's way up his shirt to trace over his trembling torso. Little bumps erupt all over his skin when the tip of his cock catches in your little divot. You can't help your lips from curling up.

You lower yourself so your hole swallows just the tip, and his breath hitches beneath you. You clench in response, just a little squeeze to remind him who makes him feel good, who his cock really belongs too, and if the bubbling moan that passes his lips is anything to go by, he got the memo.

You ghost your lips over his neck, nibbling lightly at his sensitive pulse point, teasingly tracing a little heart over his pecs, “Just relax and let me take care of you, okay?” 

He all but whimpers as you drop yourself down, white-knuckling the sofa, so overwhelmed you swear his eyes start tearing, and when you finally reach the base he groans like he’s seen heaven. You don’t think about his wife, or his ring, or morality while you bounce on his cock. Not a flicker of guilt passes through your mind when he bucks and fills you with his cum. Why should it? Your job is to ensure your boss's needs are met while he's in the office, and you’re doing just that. His life after five pm is none of your concern, really.

—

About two months later you find an unassuming sticky note on your desk, scrawled over in his chicken-scratch handwriting.

Come to my office at 5, we need to talk.

It strikes you as odd. Normally he’d just come talk to you about any arrangements, lay a gentle hand on your shoulder and bend down to whisper something filthy in your ear, but your boss is nowhere in sight. Not on the office floor checking up on his employees, not in the break room making idle chatter while he refills his coffee, your boss stays holed up in his office all day, and when you walk in to give him his schedule for the upcoming week he only grunts in acknowledgement, never looking up from his computer.

Something is clearly wrong. Normally, he can’t keep his hands off of you—you never leave his office without a slap on the ass and a promise to make you regret wearing whatever curve hugging skirt you put on that day—but he seems to want nothing to do with you, or rather, he seems to be avoiding the fact that he does. The blatant disregard pisses you off, frankly. You put effort into your makeup today.

But more than that, his sudden indifference is unsettling. You can’t put your finger on why; he’s never given you reason to believe that he’s resentful, and despite his dour, professional persona he’s about as intimidating as a newborn kitten. Still, the tension in his office is thick. Thicker than you realize. When you step out you're surprised to find your lungs are aching from holding the breath you walked in with.

You spend the better part of your day trying to convince yourself that you’re just feeling ill. You aren’t nervous. There’s no reason to be. The gut feeling telling you to walk out at five today is just the byproduct of spoiled eggs at breakfast. You’re in control. You always are.

Still, when five o’clock comes your heart is pounding. Alarm bells clang in your head, screaming that something bad is going to happen if you walk through that door. Briefly, an interview from a true crime documentary you once watched plays through your head—the victim was lamenting how she regretted not listening to that “gut feeling” before she got kidnapped—but that’s ridiculous. You know your boss and you’re certain he’s not a kidnapper. The notion itself is ridiculous. You’ll be fine. You’ve been fucking him for three months, him acting weird doesn’t mean today will be any different.

After a few deep breaths you open the door and as promised, he's waiting for you, but not how you expected him to be. Normally, he’d be rolling his hips into his fist by now, impatiently demanding you get on your knees in front of him, but today he’s fully clothed, penis nowhere in sight. Instead, his hands cup a white mug of steaming liquid—an identical one that you presume to be yours sits on the opposite side of his desk—and he seems… tired. Pale and weighted; certainly not aroused in any way.

“You can sit, you know. I’m not angry at you.” he calls vacantly from across the room, not looking up from his cup.

Heat rushes to your cheeks, realizing you’ve been staring. With a thick swallow, you make your way over to him, mustering up as pleasant a smile as you can. When you finally sit and get a good look at him, however, the grin drops. 

He looks… awful. Weary and bleak, with red, puffy circles around his eyes like he’s recently been crying, his hair is mussed and a five o’clock shadow is growing on his chin. It’s jarring, to say the least. He’s normally so put together, you can’t remember if you've ever seen him disheveled. He’s a hard man to shake typically, his job demands it, but he looks utterly distraught. For a brief moment, you feel kind of bad.

Gross.

A halfhearted chuckle leaves his mouth, “I’m sorry. I must look pretty pathetic, huh?” 

Immediately you straighten, rectifying your smile. You can’t show cracks. There are no cracks, “Not at all Sir. What can I help you with?” 

A meaty hand waves you off. “Don’t bother with professionalism, Y/N. We both know we aren’t here to talk about work.” he runs a hand through his already mussed up hair and shuts his eyes. He pauses a moment, taking a long breath, thinking deeply or maybe steeling himself, before slowly exhaling, pushing the second mug towards you “Here, take a drink. This might be a lot.”

“Oh no, I’m not thirsty–”

“Drink.” he interrupts, and you’re startled by how sharp the command is. It’s far cry from the playful orders you’re used to receiving when he growls at you to get on your knees or bend over his desk. Instinctively, you find yourself rushing to obey.

When you bring the mug to your lips, his face relaxes. The alarm balls start jingling in the back of your head again.

“I’m going to be blunt about this,” he sighs, pinching the bridge of his nose, “My wife found out about the affair and she wants a divorce.”

Oh. That is a lot.

It takes you a few seconds to process what he’s saying, a few more for it to sink in, but when you’ve finally got a stable grasp on the information, the faucet of emotion is turned on. It doesn’t twist off until your body is on the verge of overflowing.

But not for the right reasons.

Your heart should be sinking, guilt twisting in your gut like a knife. You should be on your knees, groveling in shame; apologizing with your whole chest for ruining this poor man's marriage—but you aren’t. Not a flicker of remorse fills your body.

You feel positively giddy.

Elated. Euphoric. You are on cloud fucking nine. Months, you’ve been waiting for this day; when you could finally take your medal and put it around your neck. It’s not really a matter of him being yours, moreso confirming that you’re hot enough to break up marriages. Fuck the morality of it all. You did it. She’s gone. You won. 

You aren’t tactless enough to start jumping for joy, however. You do your best to put on a genuine-seeming soberness and reply, “I’m very sorry to hear that.”

He shakes his head, eyes down-turned, “I’m equally if not more to blame. What’s done is done.” 

He stands then, aimlessly walking to the window. It’s all rather dramatic, you feel, but you're not the one who’s marriage just got destroyed. Quietly he looks across the skyline, face clouding with regret as he speaks, “You should have seen her, Y/N.” You wish you had, “I-I could see her heart breaking in her chest when I admitted to it.”

Oh, the delight that runs through you when you hear that crack in his voice—it makes you dizzy.

“I managed to find an apartment somehow between then and now. I’m in the process of moving in. I thought it was only right to give her space. God, the poor girl…” His cheeks are wet when he turns back to you and another jolt of glee zips through your body. But this one is stronger than the first one. It makes you wobble a little in your chair; you have to clutch the armrests to keep yourself upright.

The bells have started clanging again—painfully loud—and your heart beats in time with each stroke.

“Seven years. We’d been together seven years.” he laments, walking back to you and placing a gentle hand on your shoulder. Despite the touch's innocence it’s searing hot, burning into your skin like an iron, only serving to make the bells louder. You try to jerk away but your body goes slack and when you try to pick yourself back up again, you can’t; no matter how hard you strain and lift, your muscles won’t move.

Your heart is pounding in your head now. His large hands hook under your armpits, hoisting your limp body back up onto the chair like a ragdoll. 

A sick, crawling feeling of dread fills your chest, like when you get to the very top of a rollercoaster. It creeps up your spine and wraps around your chest, squeezing the air out of your lungs. His face… he looks like a madman. Pale and wild; eyes manic and pupils dilated. He swallows heavily, breath shallow and frenzied as he desperately rasps, “I don’t think I could live without a wife again.”

The bells are deafening now and any ounce of joy you might have felt earlier has been drained to oblivion. You aren’t fine anymore. You need to run. You need to scream. Anything.

But you made the realization all too late. Your vision is going spotty and he’s already hoisted you up in his arms. Despite every muscle in your body fighting with all its might, you can’t make yourself move.

For the first time in your life, you’re completely powerless. 

The last thing you remember before being swallowed by the dark is his hot breath puffing against your ear:

“You promised you’d take care of me, didn’t you?” 

—

You wake up to the feeling of something warm and wet on your clit.

In your groggy, half-conscious state you don’t have the capacity or desire to figure out what it is, all that matters is that it feels good. It flicks lazy little shapes over the twitching bud, enveloping it and your folds in a warm, welcoming heat, and for a moment, you think you could die happy just like this. Your hips instinctively buck up towards the source and a low, wonton moan passes your lips. 

“Mmm, thats it darling. Good girl~”

Your eyes fly open.

Every ounce of blood drains from your face when you see his head bowed between your legs, cheeks messy and shiny with your slick, hips rutting needily against the mattress. Your kidnapper.

Your first instinct is to fight, but your limbs still won’t obey you—even if they would, a shift of weight reveals that your hands are bound tightly to the headboard of the bed.

The bed. There’s no bed in his office. Where the hell are you?

It’s all you can do to let out a low, displeased whine. Weakly shimmying your hips away from him only to have them immediately yanked back. He peaks up from your legs, “Shh honey, calm down.” he purrs, not breaking eye contact as he gives your clit a sweet peck, “Just relax and let your husband make you feel good.”

Husband.

Husband.

Your heart picks up in your chest, galloping like a racehorse as you try to process his words. “W-what?” you choke, even drugged your voice is sharp with terror.

He noses gently over your inner thigh, carefully pressing a chaste kiss to the soft plush before addressing you, “Your husband, dear. And you’re my wife~” he hums pleasantly, licking a long lazy stripe up your slit with the flat of his tongue, “I’m sure you can feel the ring, right?”

Your heart drops as you wiggle your fingers. On your left hand, a cold band of metal topped with some kind of stone wraps around your ring finger. A bout of vertigo flashes through your body. He must notice the horror on your face because he chuckles.

“It was kind of short notice so I had to use hers, but I’ll buy you a new one if you want…” he trails absentmindedly, too focused on laving at your cunt to give the thought his full attention. 

He’s doing it just like you taught him too. The irony could make you cry.

A knot the size of the watermelon grows in your stomach. Whether it’s from the panic or your equally distressing impending orgasm you’re not sure. Regardless, it’s there, and your head is spinning, and he’s starting to climb on top of you and take off his—oh god.

You cry and struggle as much as your leaden body will allow but he easily counters it all with one steady hand on your belly, the thumb of which he moves down to nurse your spit-soaked clit with easy circles. “I know it’s sudden,” he coos, paying no mind to your cries and pleas for mercy as he pulls out his rock hard cock, “But you wanted this, didn’t you? You’re the one who chased after me so desperately after all. I know you were just jealous of her.” 

Loud, wet sobs curl up your throat as he rubs his cock up and down your dripping folds, hypnotized by the lewd, clicking sound your juices make. “P-please.” you beg, trying your best to buck him off of you, “M’ sorry! I-I didn’t mean to—Please let me go.” 

A displeased hum then, “It’s too late for that, honey, but you don’t have to worry. I’ll take good care of you.” his frown flips to a soft smile. “You’ll take good care of me too, won't you? just like you promised.”

You feel like you might faint. The blunt head is pushing against your entrance now, threatening to sink into your heat, and though you’ve taken his cock hundreds of times, you’d rather stick your hand into an open flame then take it again. “P-please.” you blubber, “I’ll do anything, just please—Ah! S-stop!”

He doesn’t acknowledge you, only continues his rambling. “You’ll take good care of our children too, I'm sure.” those deranged, lovesick eyes bore into your skull, “Oh, baby. You’re going to look so beautiful when you’re pregnant, I can already tell. So, so pretty, all swollen and glowing~” he groans.

Your eyes blow wide and you start screaming. Half of it is incoherent, but what else are you supposed to do when you can’t fight? You nearly choke on your own sob as he leans over your body, starting to push in with a low, heady groan. “You can’t!” you cry, near hysterics, “Please, you can’t! I’m sorry! I’ll do anything! I’ll-”

“Shhhh,” he cuts you off, clamping a rough hand over your mouth, then bottoms out inside of you with one languid push. You feel like you’re on fire, like a million ants are crawling up your skin and down your throat.

Beads of cold sweat trickle down your back as he rocks into you. Behind his mitt you plead for him to let you go, but he doesn’t notice, or more likely, he doesn’t care. “I think I want three." he muses, "Two girls and a boy. But we can have more if you’d like. What do you think, darling?”

He removes his hand then, you greedily suck in air. It proves to be a difficult task, however, with his dick poking it all back out again with each snap of his hips. Finally, you collect yourself enough to make one final attempt. You stare up into his eyes, hoping to somehow access whatever humanity might remain there. “Please. I don’t want kids. I want to go home.”

He pauses, ceases his thrusting, and stares back down at you. For just a moment, your chest swells with hope.

But then he laughs. A sick, evil chuckle that rings through your bones, punctures your lungs and splits your heart straight down the middle.

“Oh honey, you are home.” he croons, a snap of his hips punctuates the sentence. “And of course you want kids. All husbands and wives who love each other very much become Mommies and Daddies. Besides—”

His hips start driving into you with a brutal sort of ferocity, and he grins so wickedly you swear you can see the devil in his eyes.

“--Won’t it be cute to tell them how Daddy and Mommy fell in love at work?”
