Summary:

Nanami Kento is a domineering, powerhouse attorney by day, and an obedient submissive by night. But what happens when his two world's collide when his domme joins his law firm?

Notes:

Shout out to my girl Quay for coming up with this idea on twitter lol

Work Text:

Anyone who has ever known Nanami Kento, would never describe him as a nice man. Granted, he was nice enough ; very polite, always professional and straight to the point. But he was not necessarily approachable or friendly. Very Type A personality. 

 

So needless to say his law firm had a huge turnover rate for legal secretaries because they couldn’t deal with him for more than a few months. 

 

————————-

 

“Another one?” Nanami says as he rolls his eyes. Disinterest etched in his frown lines as he flips through case files. 

 

“Yes, Kento, another one,” his colleague, Gojo says, “there is no doubt that you’re a brilliant litigator but we are up to our fucking eyeballs in work that a legal secretary should be doing. So be nice to this one please?”

 

Nanami rolls his eyes again. He could not understand why it was so hard for these airheads to follow simple instructions. He certainly knows how to-

 

“Fine, whatever. When does she start? Miss…?”

 

“Y/n,” Gojo responds, “and she starts today she’ll be in at 9.”

 

Nanami freezes. That name makes his heart beat out his chest and his hands tremble. Trying to keep his cool he suddenly is out of his chair and rounding his desk. 

 

“Uh I’m sorry did you say y/n? You have her resume?” He was panicking internally. No way it’s who he thinks it is. It couldn’t be. 

 

Gojo racks his brain, oblivious to Nanami’s wide eyes, “yeah check your email I forwarded it to you when I hired her a couple days ago.” With that he turns on his heels and leaves the office, saying something over his shoulder about lunch. Nanami wasn’t even listening. He immediately is in his email filtering by Gojo Satoru and there it is - subject line New Hire Legal Sec Resume and Credentials

 

When he opens it and sees your name sprawled across the top of the document he panics. This can’t be happening. See the problem is, Nanami already knows you. VERY well. He just saw you the night before. Except when he did he was handcuffed and gagged, being stepped on by you in black patent leather stilettos. The thought makes him shudder before he regains his composure. He checks the time to see if he can call to cancel you coming. 8:43am. Shit. 

 

As if summoned, there was a knock on the office door before swinging open. Nanami’s eyes blow wide as he sees Gojo stepping back through but behind him was you . You give him a polite smile, but he’s known you long enough to see the sadistic glint in your eye. You are dressed professionally which is a stark contrast to the black leather garter belt and pasties he is used to seeing you in. 

 

Nanami blacks out during the introductions a bit because all he can think about is every depraved, sick thing you have done to him in the past year. It was like a compilation of clips rolling through his mind. You’re a pro though; pretending this is your first time meeting, so enthusiastic to start working for such a successful lawyer, layering the charm on thick. He tunes back in when he sees Gojo trying and failing to flirt with you a bit. If only he knew

 

Thankfully Gojo gets pulled away for something urgent leaving you two alone in the office. Nanami was itching to rectify this because he could NOT have you here. There is absolutely no way he could have his domme as his secretary. No fucking way. 

 

You on the other hand found this coincidence fairly amusing. Standing up straight in your skirt suit and high heels, you clasp your hands together behind your back as you tilt your head at the trembling blond. “Don’t worry, Ken, we still have the NDA,” you slowly approach him and speak softly, “your dirty little secret is safe with me.” You smile even wider as he takes steps back every time you step forward. It’s not until he bumps into his chair before falling into it before he speaks. 

 

“What are you doing here? How did you even-“

 

You hold up a hand and on instinct he stops talking. “Relax, baby,” you coo at him, “we don’t really do a lot of pillow talking so it’s no surprise you didn’t know I was in law school. This job sort of just fell into my lap. It’s a pretty funny coincidence if you think about it…how weird is it going to be with you giving me orders, huh?” Nanami audibly gulps before slowly closing his eyes. You laugh at his discomfort. 

 

Nanami has a death grip on the arms of his chair as he works through his mini panic episode. This was not good as far as he’s concerned. He spends all day giving orders, commanding respect and having to be the one everyone always comes to for everything. That was him during the DAY. But at night, he was in need of some kind of relief. And once he stumbled upon your site as a domme looking for male subs, his life changed forever. He LOVED relinquishing all control over himself to someone else, and you gave him that. Even for a small bit of time. You were perfect. You seem sweet and delicate but you were truly a force to be reckoned with behind closed doors. You were vicious; domineering, nonjudgmental, and sexy as fuck. Good lord were you sexy, it was debilitating. 

 

You snap him out of his thoughts by sitting on the edge of his desk right in front of him in his chair. Suddenly planting your stiletto on the seat between his open legs, just close enough to his crotch to have his breathing erratic. “I told you to relax , Ken,” you say to him in that voice. “This can either be easy,” you slide your foot up a bit, the pointed toe of your shoe grazing the seam along the zipper of his suit pants, “or I can make it very, very hard.”

 

“Oh fuck,” Nanami groans as he watches your foot, “please…”

 

“Please what?” You say sweetly, “don’t forget yourself, even here.”

 

Nanami was not mentally prepared to fall into sub space during the work day. The familiar throbbing in his pants coupled with the perspiration gathering at his hairline was an indication that it was happening anyway. 

 

“Please…Mistress, I need a moment,” he was struggling to find words. His worlds were colliding way too fast for his liking, “why don’t you umm, go unpack your desk and I can give you your workload later? ….please?”

 

With a satisfied smile you slowly put your foot to the floor and gently caress his chin. Like butter he melts into your touch. “Always so polite. And to think, I was concerned when your partner said you would be difficult to work with,” you tighten your grip and force him to meet your gaze, “you’ll be a good boy for me, won’t you?”

 

“Yes Mistress,” Nanami answers quickly. For what it’s worth Nanami was a perfect submissive. Very communicative, respectful of his boundaries and yours. 

 

You hum with satisfaction as you release his face and stand, turning to leave. The second you step out of Nanami’s office he releases a shuddered breath he didn’t know he was holding in. This was going to be harder than he thought. 

 

————————-

 

Nanami was infamously known in the office for his temper. Over the last few weeks rumors and praise spread about how he has been so pleasant to work with since you joined the team. It didn’t go unnoticed how he seemed to regulate himself whenever you were in the room; even going as far as including ‘please’ and ‘thank you’ when addressing his coworkers. Additionally you quickly became an office favorite. Always extremely nice, willing to be of assistance and even making your voice heard without overstepping your position. Nanami’s conflicting feelings about you as his domme and his employee has him so stressed, that he hasn’t made any appointments with you since you started. You watch him day by day looking tense, as if he was constantly on edge. You’ve known him and this line of work long enough to know that whatever release he was giving himself was simply out of necessity and not letting himself truly indulge. So you figured you needed to fix it since the polite man won’t ask. 

 

“You haven’t come to see me in a while,” you say as you lean forward and brace your arms on your crossed legs, “why is that?”

 

You were currently sitting opposite Nanami on the leather sofas in his office, going over court documents for an upcoming case. It was about 10 pm, the rest of the office long gone including the janitorial staff - leaving you two completely alone. Perfect opportunity to address the elephant in the room. A sly smile crosses your face as you watch him nervously run his fingers through his unruly hair at your question. Taking in the rest of his appearance, you notice his tie is loose, sleeves rolled up and his suit jacket tossed haphazardly on his desk. 

 

“I figured it was for the best,” he responds with a bit of edge in his voice, “you know, conflict of interest. Plus I’ve been taking care of myself just fine” He lied. But he couldn’t very well explain it’s because watching you saunter around the office with that dominating presence and gorgeous ass in your skirts, was turning him on more than he could ever imagine. Seeing you smile that mischievous smile at the board members usually reserved for your good boys . Hearing the deafening clack of your heels down the hallway; the same heels you used to step on his cock many, many nights before. Watching you shake hands with clients with the same firm grip you used on his cock-

 

“You’re lying,” you say with a playful lilt to your voice as you study him. You uncross your legs and recross them in the opposite way, flashing your bare pussy in the process. Nanami’s quick gaze between your legs was fast but not quite fast enough. Making a show of roving your hands up your thighs, watching his eyes follow the movement, “Such a shame you stopped coming back, you really were my best boy.”

 

Nanami’s breath is stuttering as the rest of his composure begins to slip. “No panties?” You shrug before deciding to up the ante; you spread your legs and hike your skirt up a bit so he has a full view of your cunt. He watches intently as you drag two fingers along your slit, gathering the slick there. You suddenly stand and slowly walk around the table in between you two, to stand directly in front of Nanami’s open legs. He looks up at you and gulps loudly, nervously flexing his hands resting on his thighs, as you look down at him over your nose. You grip his chin and tilt his head upwards to look at you dead on, prying his mouth open. He doesn’t even break eye contact as you press down on his tongue with your slick-covered fingertips, making him whimper softly. With a knowing smile, you know you’ve got him.

 

“Down, boy,” you say in a low, sultry voice. Nanami slowly slides off of the leather couch and drops to his knees and crosses his wrists behind his back, with his chin still tilted upward to look at you. “See I knew you couldn’t resist, baby, I know what you need. Didn’t you miss mommy?”

You watch as Nanami’s eyes start to glaze and releases a deep sigh, “fuck yes, I missed mommy.”

 

“Well don’t worry, I'm gonna take good care of you okay? Remember your safe word, sweet boy,” you warn as you reach down and grab the end of his loosened tie, pulling the fabric and adjusting the knot until it resembles a leash. You begin walking backwards, taking Nanami with you as he falls to his hands and knees, crawling after you. Shamelessly panting as he crawls all the way to his desk as you plop down in his chair. You guide him to sit up on his knees with his back to the large floor to ceiling windows behind the desk. The position of the chair in front of him gives you a good view of the bustling nightlife and bright traffic lights through the glass. Nanami’s office was only on the sixth floor, so if someone down below looked up, they would see the both of you.

 

Nanami did not seem to care as he patiently sits with his wrists crossed behind his back like before, waiting for instruction. You scoot to the edge of the chair, spreading your legs wide and planting one heel against the glass window right by Nanami’s head, and the other resting on his thigh. With the makeshift leash still in hand, you yank his face close to your waiting pussy. The heat and sweet aroma radiating from your core was making his mouth water in anticipation, but he knew better than to dive right in.

 

“Well what are you waiting for, Kento?” You were taunting him. Relishing in his obedience.

 

He licks his lips as he breaks his gaze on your cunt to meet your eyes once more, “for permission, Mistress. Can I please eat your pussy, mommy? I want to make you feel good.”

 

You hum as you address him condescendingly, “naughty boy wants to eat my pussy in front of all those people down there, huh? So greedy. Say it.” With a tilt of your head you yank on the tie awaiting his response. Nanami groans as the shame goes straight to his throbbing cock, his pupils blown wide.

 

“I want to eat your pussy, Mistress, in front of all of those people….because I’m greedy,” he sobs softly. Growing impatient, he leans forward and gently kisses your knees and licks along the skin of your thighs. Your foot at his thigh shifts to his crotch and you put pressure on the balls of your feet, slightly crushing his erection. The strangled moan Nanami lets out is pathetic as he starts thrusting his hips to rub against your foot. He drags his panting mouth up under your skirt to lick along your folds. You toss your head back against the chair as Nanami eats you with a renewed enthusiasm. Slurping loudly on your clit as he teases your entrance with the tip of his tongue. He groans in pleasure as he swallows your essence, letting it coat his cupid’s bow and chin.

 

Your leg braced against the window begins to tremble as each pass of Nanami’s mouth shoots pleasure through all of your limbs. You tense as you pull him closer by the neck, grinding your cunt against his face. With your free hand you start unbuttoning your blouse; with some work you were able to work it off of your shoulders, allowing you to unhook your bra. The lacy garment soon joins your blouse on the floor, leaving you in your bunched up skirt.

“Oh fuck, Kento, I’m gonna cum,” you breathe out as you pinch your nipple for added stimulation, “permission to touch me…make me cum.” The way you managed to sound commanding even when you are reduced to moans, could have Nanami cumming from dry humping your heel. He uncrosses his wrists and grabs you by your thighs pulling your dripping pussy against his face. You begin to pull the tie/leash around his neck, tightening the hold as you teeter on the edge. All of a sudden you are cumming, violently shaking as you pull the leash tight, making Nanami light headed as he tongue-fucks you through your spasms. As you start to come down, he is still desperately slobbering on your pussy, moaning in satisfaction as he gets lost in you.

 

It was too much. You slide your foot at his crotch up to his chest to push him back against the window. “Eager, eager boy,” you say in a low voice, “have you no shame? Reduced to humping my foot and begging to eat my pussy. You wanna fuck me, baby?”

 

Painfully hard in his slacks, Nanami blinks at you and licks along his chin before responding, “I just want to please you, Mistress. Just tell me what to do and I’ll do it; I’ll be whatever you tell me to be. Please.” With your foot still pinning him to the glass, he begins stroking himself over his pants, whining desperately. You consider him for a beat before pulling your foot back and crossing your legs.

 

“Anything huh,” you reach forward and give him a patronizing pat on the cheek, “then you are a fuck toy. You will take pleasure however I decide you deserve it. Clear?”

 

Nanami nods quickly, “yes, please Mistress, use me however you like.”

 

Leaning back in the chair, you eye him up and down, “strip. Then turn around, hands on the glass.”

 

With no hesitation, Nanami quickly frees himself of his clothes and faces the glass, looking at the patrons walking below and the blinding lights of the zooming traffic. He was full frontal, throbbing cock dangling in the window. The embarrassment he felt was fueling his desires like no other. Suddenly you stand and move directly behind him. You look around his arm to see what he can see through the window as you reach around to wrap your warm hand around his cock. He hisses at the contact before letting out a garbled moan when you reach your other hand between his legs from behind to palm his balls. Simultaneously you twist your wrist to stroke his cock while you massage his balls that are drawn so tight, it hurts.

 

“Filthy boy, you’re gonna cum for all of those people,” you rasp against the nape of his neck, “they’re all gonna see that pitiful face you make when you cum.” You stroke him faster and faster as Nanami cries in pure bliss. His legs begin to shake as you drag the pads of your fingers on his balls, back to his ass hole. Without pressing in, you gently tease the tight button of his ass as you stroke his cockhead.

 

“Holy fuck, I need to cum,” Nanami whimpers out quickly, “Please oh fuck let me cum.”

“Please what, baby?” You tease, unfazed by his anxious need to get permission to cum. If he does it without your say so then you get to punish him.

 

Please, Mistress ,” Nanami sobs out unabashedly, “feels so good, please let me cum. Can’t hold back.”

 

Satisfied with his begging you hum in approval, “go ahead and cum for me then, sweet boy.” Just as you gave the command, you push in the finger massaging his hole just to your first knuckle as you stroke him base to tip. The throaty moan he lets out is accompanied by trembling legs and thick spurts of white cum, splattering against the window. Nanami lets out labored breaths as his vision refocuses. He  swore he saw someone walking down below stop and look up…

 

“Dirty boy, you made a mess,” you grab his shoulder and push him down to his knees and grab him by the hair at the back of his head, “clean it up.” Like a depraved whore, Nanami leans forward and drags his tongue through his release, effectively gathering every drop as you watch. The tight grasp you have on his hair limited his movements but he was basking in the tiny bit of pain. This degrading act has his cock twitching back to life, wanting nothing more than to be used by you some more.

 

Once he finishes you praise him for a job well done. Watching the way Nanami just obeys you regardless of the instruction was the best thing about fucking him. After you prompt him to sit in his office chair, you dig into one of his desk drawers and pull out one of his spare ties. One by one you tie his arms to the arms of the chair, testing them to make sure they were snug. Satisfied, you climb into his lap to straddle him, gripping the back of the chair for stability. 

 

You ghost your lips over Nanami’s as you speak, “do you think you deserve to fuck me, Kento?” Nanami balls his fists, pulling against his restraints as he begs you once again, “oh please, Mistress, I’ve been a good boy. Please fuck me. Please . I miss your pussy so much.” You crack a smile as you grab his cock and line him up with your dripping hole.

 

“Don’t cum until I do,” you warn him as you slowly begin to lower yourself onto him. The thickness of his cock creates the most delicious stretch as you rock back and forth, impaling yourself. Nanami’s eyes flutter as the velvety warmth of your cunt envelopes him in a death grip. Once he nestled all the way to the base, you use your thighs to rise up to his tip before slamming back down. Bouncing fervently in his lap has a string of curses and moans falling from both of your lips. Anyone walking on the ground below would have a perfect view of your ass flashing in the window. The thought excites you, giving you the energy to ride faster. You move your hands from the back of the chair to wrap around Nanami’s neck, squeezing lightly as you roll your hips to grind your clit against his pelvis.

 

“Oh fuck, Ken you’re so big,” you moan loudly as sweat rolls in beads down your face, “you fill me up so good.”

 

Nanami’s eyes roll to the back of his head as he grips hard on the arms of the chair, doing everything in his power not to fuck up into you. As you release his throat, you rise up and Nanami slides right out of you and you turn around in his lap. You line Nanami back up and slide back down with ease and immediately resume bouncing on his pulsing cock. Your second orgasm was building in your gut fast so without stopping, you untie Nanami’s arms and lean back against his chest.

 

“Touch me, Ken, make me cum again,” you twist your face to lick along his cheek. Nanami plants his feet on the floor as he reaches around to rest an arm on your waist and the other down below to tease at your clit. He buries his face in your neck and groans in response to your weak cry as he rubs tight circles on your bud. His constant whimpering in your ear has your climax right on the horizon.

“Cumming, Ken,” you mewl softly, “as soon as I cum you can cum.”

You bounce harder and faster as Nanami’s fingers match your speed. With a broken cry you convulse in his lap, clenching hard on his cock. The sudden vise grip sends him over the edge for the second time of the night as well.

 

“Oh, shit, thank you mistress for giving me your pussy,” Nanami rasps as he fucks his seed deep inside your walls. Once he stills, he leans his forehead on your spine and takes a few deep breaths. You stand up and wince at the sudden emptiness as his cock slips out and falls against his thigh, soaking wet. You turn around to face him and brace your weight on the arms of his chair caging him in.

 

“Don’t worry about paying for this session, by the way. This was as much my pleasure as it was yours.” You wink at him as you go to gather your clothes leaving him in a sweaty, sated mess.
