“i hope this is gonna be worth it..” denki mutters under his breath as he adjusts his office to get ready for the interview he has in less than five minutes.
he really didn’t want for things to come to this- having to fire two PAs in the span of a year. he thinks it makes him look unprofessional and unreliable but he did it for a good reason. the women he hired were young, which in itself, nothing wrong with. but young women with a mindset of “i get to be around a hot hero all day” does eventually become a problem when he’s being flirted with on a daily basis rather than helped like he should.
he feels guilty about making the choice he did, but if wants his agency to stay running and not crash and burn, something’s got to give.
“chargebolt, your interview is here” one of his sidekicks pops their head in to tell him.
“send her in” denki says with his usual boyish smile while standing at the age of desk.
soon enough, you walk in, greeting him with a polite smile and small bow.
“hello chargebolt, my name is y/n. it’s nice to meet you” you greet him before he could even form a thought, hand extended for a handshake.
he buffers for a full second. cause god you were so gorgeous. wait wait remain professional denki! he takes your hand with a small laugh for a handshake and bows slightly in return.
“just call me denki, it’s nice to meet you too, y/n” he replies politely before you two let go from the handshake. “take a seat let’s go over your application.”
“you’re hired” denki speaks. the interview had been going well, so far already fifteen minutes deep into it and he’s definitely made his decision.
you’re a little shocked by how fast he decided that decision. no need to look over interview notes he didn’t take any or give you a call back. just immediate hire.
“oh, well thank you denki” you reply with a soft shocked giggle.
“does tomorrow at eight am work for you?” he asks politely.
“yes of course! i’ll be here then” you reply with a polite smile.
denki rises out of his seat and you do the same, the two of you exchanging another handshake. “welcome to the dream team y/n” he says with a smile.
you can’t help but playfully roll your eyes at his words. “i’ll see you tomorrow at 8” you say.
the next day comes faster than expected, but what’s also unexpected is how fast you’re able to pick up on the new job.
memorizing and organizing schedules for not just denki, but some of his closest sidekicks is something you managed to pick up on quite well. which, truth be told, denki is so grateful for because his last PAs barely knew organization skills for a schedule so he felt like having a stroke everytime he looked at the schedule.
“you’re an angel miss y/n” denki says gratefully as he looks over his own schedule on his ipad. “this is so well organized holy shi-“
“it’s my job, i don’t half ass it” you reply with a small smile at your desk, typing up some documents that were messily written for denki.
“yeah.. you really don’t” denki says, more to himself than anything as he continues to look.
“you’ve been working all morning, take a lunch break- better yet don’t even clock out for it just go get something to eat i know you’re hungry” denki says as he looks up from his ipad.
“you sure about me not clocking out?” you ask with an eyebrow raise.
“absolutely. if you can make a schedule this organized that even i can read it you deserve a paid lunch break.” he replies with an eager head nod. “actually better yet lemme pay for your food while you’re at it too cause you deserve it for this fire ass schedule” denki says, clearly really happy and pleased with your organization skills for something as simple as a schedule. what can ya say? he’s easy to please!
and how can you say no to that? sure you can pay for your own. independent woman with your own means, but hello if a man is gonna offer to pay for something it’s smart to not say no.
“i mean if you’re offering who am i to say no?” you reply with a small giggle before doing a quick stretch and standing from your desk.
the walk to the little cafe was nice, but you learned quickly just how much denki actually talks and doesn’t know how to shut the fuck up. not that it’s a bad thing! but lord have mercy does he have a big mouth on him.
the two of you are inside, seated at a booth with some food. you’re finally talking until denki interrupts you.
“i like your voice” he says casually with a boyish grin before eating a fry from his meal.
you give him a confused look, raising your eyebrow slightly. “thank you? i think?” you say. “i can’t tell if you’re trying to flirt or if you-“
“doesn’t matter, not like we’re at ‘work’ ya know?” he says rather straightforwardly trying to be smooth.
“we’re on the clock though.” you state as a matter of factly.
“i meannn i am your boss too but im just choosing to ignore that right now” denki replies with a shrug, not in a rude way at all, quite the opposite, almost like he’s teasing and making a little joke out of it.
you blink at him before sighing to yourself, choosing to not entertain this anymore. “okay whatever, anyways-“ you say as you continue back to what you were saying.
over the next few days, you settle into a rhythm that even the agency admires.
and denki? oh. he learns very quickly the things you won’t tolerate. late or missed meetings, sloppy paperwork, also excuses disguised as jokes. and to his very own surprise, he finds himself adjusting.
he starts showing up on time, doubling checking the very neatly made schedule that you made and he literally praised you endlessly for, he even starts asking questions instead of brushing things off automatically like he usually does. 
it should be a good thing. in fact it is a good thing.
so why do you feel like he’s watching you more than he used to?
let’s be real- you’re not really insane for thinking he is. denki is a lot of things but unfortunately for him subtle is NOT one of them.
lingering eye contact and looks, you can always feel his eyes on you before you look over. he always listens to you when you speak, always. and he’s grown a means of also remembering things about you too. which is why only a week into work, you now have your favorite drink on your desk waiting for you every morning.
it’s late in the agency, the humid air outside clashing with the chilly air inside causing condensation on the windows and the outside city to look a blur.
despite you being here for only little over a week, you’ve made it a habit of leaving at when you’re supposed to. but today a lot of paper work came through from dynamight’s agency while denki was on patrol so you’re trying to play catch up on it for him.
denki eventually walks through the office doors, surprised to see you still there. he had just got done with patrol for the night and was about to grab his laptop to do said paperwork at home.
“what’re you doing here so late? you should’ve went home-“ he glances at the clock on the wall “-almost two hours ago, y/n” he says rather softly and confused.
you glance up at him from your seat “oh just helping you out on your paperwork is all” you say casually before redirecting your eyes back to the computer and continuing to type.
denki studies you for a moment longer before replying. the curve of your jaw, the way your hair falls, your concentration look as you type, and god those plush lips he wish he could-
“you always like this?” he asks before he could trail off any longer, walking until he was at the edge of your desk.
“like what?” you reply, not even looking up from the screen.
“this..” he gestures vaguely with his hand “put together”
you pause your typing before looking up at the boy, your hands moving from the keyboard to rest in your lap as you look up at him.
“lemme ask you something” you speak
“yes ma’am” denki replies almost immediately it’s comical
you shake your head at that with a small fond smile. “you always like this?” you ask him
now it’s his turn to be confused, he tilts his head like a confused puppy “…like what?” he asks
“observant.” you speak before suddenly standing from your chair. “or better yet” you continue as you walk until your just a few feet in front of him, considering he’s hovering over your desk “you act like your subtle when you’re not”
denki stills at that for a moment, almost like the words actually landed and caught him this time.
he scratches the back of his neck, almost sheepishly “am i that obvious?” he asks, a little quieter now.
you tilt your head at him slightly, crossing your arms while studying him for a second longer than necessary.
“you’ve been staring at me all week, denki” you say. there’s no accusation in your tone. if anything it’s really observational and bordering factual.
denki’s lips opens like he’s about to deny it, avoiding your gaze, before he closes that motor mouth of his just as fast.
“..yeah” he replies just as softly as before.
his honesty sits heavier in the room than anything else he could’ve said in there in the last week and a half of you being there.
your eyes narrow just a fraction, not in suspicion but rather in thought as denki brings his gaze back to yours.
“and you don’t think that’s a problem?” you ask
he lets out a quiet breath, almost like a sigh as his gaze looks up at the ceiling before it drops back to you again “i think..” he starts, trailing off slightly before trying again with a sigh. “i tried to make it one. y’know.. keep it professional. not be weird about it or anything but, you make that kinda hard” he admits
you don’t react to his words right away, instead, you take a small step closer to him. just close enough to close the gap between you two.
“denki” you say a bit quieter now “do you even realize what you’re saying right now?”
he blinks at you, caught somewhere between confused and focused “yeah?”
you hold his gaze like you have been, steady. “i’m older than you.”
it’s not like it’s a warning, more or less like a fact. “i’m your employee. and you’re my boss.”
silence hangs for just a few seconds before you break it again “and yet, you’re the one looking at me like you’re waiting for permission”
something in denki’s expression shifts at that, like the realization hit him all at once. not embarrassment, not hesitation. instead something warmer, heavier.
“maybe i am” he admits, just as quiet.
you sit with his response for a just a beat before uncrossing your arms and shaking your head slightly “you don’t strike me as the type that waits”
denki gives a subtle shrug his eyes locked onto yours now “not usually.” he admits “but you’re not usual”
his words hang in the air, heavier than they should be while neither of you move. your gaze flicks down from his eyes to his lips just for a second before returning to his eyes. subtle, but not enough.
“you’re still at work” you remind him quietly.
he acknowledges what you said, but that doesn’t make him back off. “yeah” his eyes fixated on your lips for a moment “i know”
“then act like it, hero. keep some distance” you say “or is that too hard for you too?” you say, almost challengingly.
denki exhales softly, but he doesn’t move, no. not even an inch away from you.
your eyes flick back up to his, something unreadable passing through your expression for just a second.
both of you are quiet now probably the quietest you’ve ever heard denki. the air between you two becomes thicker with what’s still unsaid, almost like one wrong move and it’ll snap completely. you can feel the warmth coming off from him from how close the two of you are standing. a faint smell of sweat from his patrol mixing with his good cologne starts to fill your senses and where did he get his cologne cause hello perfume don’t last that long?!
denki raises his hand slightly, almost hesitantly, like he’s giving you one last chance to stop him. but instead, you don’t.
his fingers brush against your wrist first, light, barely there. almost like he’s testing something. and instead of pulling away, your hand shift, making the touch more intentional.
his gaze drops again, this time slower. more deliberate. “still want me to keep my distance?” he asks quietly.
“oh whatever” you say as you roll your eyes, grab his jaw and pull him as your lips meet his, harder than expected, controlled but anything but gentle.
denki immediately melts into the kiss with a groan, allowing you to take full control over it as his hands find purchase at your waist, pulling you impossibly closer.
your lips are so much softer than he could’ve imagined, warm, and slightly wet from the gloss or balm you used.
your tongue invades his mouth as your hand move from his jaw to his throat- choking him ever so lightly that denki genuinely moans. he moans at the feeling of your hand around his throat. he’s nothing less than putty in your hands at this point.
eventually, the two of you break away, a little reluctantly on denki’s part as he slightly chases your lips once you two part.
his eyes are hazy, half lidded, as he pants slightly while looking into yours- his hands still on your waist.
“cmere” you say as you motion for him to move towards you as you prop yourself up on your desk. your feet dangling as you look up at him.
and of course denki listens, murmuring a soft “yes ma’am” before he’s standing directly in front of you.
“touch me and i’ll let you have a treat” you say, head slightly tilted with a little hint of a challenge in your voice.
denki hesitates for a moment before replying “..touch you how?”
you scoff and roll your eyes, grabbing his wrists and moving his hands until his palms are resting over your clothed boobs.
“touch me. please me. you wanna be able to taste me yeah?” you ask him with a look of curiosity but mostly one that says you’re more than sure of what he wants.
and lord and behold, denki whines at your words. god, something he’s wanted since he met you. to taste your sweet essence from your pussy. yeah, it’s a little shameful to admit considering how low long he’s been having thoughts about you, but he doesn’t even worry about that. not when he’s this close to getting what he wants and probably more.
he nods urgently at your words, his hands moving to unbutton your dress shirt just enough to expose your bra before his hands slip under your straps to pull your cups down. exposing your boobs to his full display.
his hands immediately get to work, his fingers flicking and pulling at your nipples, causing soft moans and whines to escape your mouth as your head falls back.
and god the sight before him.. his hero suit pants feel so goddamn uncomfortable right now. his erection hard and tight against the constraints of his pants. he wants to be touched so bad but his main concern right now is you.
feeling a little braver, his head dips down, kissing along your neck as he moves lower until one of your nipples are in his mouth and his hand moves to roll your other nipple between his fingers.
he sucks and licks against the bud, letting his teeth graze against it juuuust right to cause pleasure rather than pain. and it must be working considering the sweet delicate moans falling from your lips.
one of your hands find purchase in his hair, tugging at the roots slightly causing denki to whine in response. his dick is throbbing at the tugs on his scalp.
“such a good boy, you like when i pull on your hair, hm?” you ask him as your other hand joins his scalp to give a sharp tug.
your nipple leaves his mouth as his head falls back with a loud whine at that. “yes ma’am, i do i do” he replies urgently, his dark needy gaze meeting yours.
you can’t help but grin at how responsive his. how good he is.
“i think you’ve earned your reward” you say as your hands move from his hair to caress his cheeks with your thumbs. “cmon, help me outta these” you say as your hands move to your slack covered thighs and give them a light pat.
denki nods, his hands moving urgently to help you out of your slacks. unbuttoning them as you raise your hips to let him take them off leaving you in your panties.
he stares for a moment- you’re wearing white cotton panties- nothing special. but, he can see just how aroused you are considering the obvious wet spot that’s in them.
but he doesn’t get caught up in staring for too long before he’s hooking his fingers at the waistband of your panties and pulling them off of you too. he crouches down in front of you once they’re off, the panties still in his hands.
he looks up at you for a moment, before down at the cotton material in his hands, before he can overthink anything any longer, he brings it to his nose and takes a deep inhale, whining and palming himself slightly as he does. and lord it’s a hot scene to witness.
“naughty boy, who knew you were into such things” you say, your hand moving to rake through his blonde hair.
he pulls the cotton down from his nose, looking up at you finally “i’m into a lot of things” he replies with a boyish grin.
he drops the cotton material to the floor before his hands and arms lock around your thighs to drag you closer to the edge of the desk. your glistening pussy right infront of his face where he’s knelt on the floor.
“may i?” he asks as he looks up at you, his thumbs rubbing your thighs.
you smile slightly at him as you give the blonde a nod “go ahead, put that motor mouth to use other than talking”
and as soon as those words leave your lips, denki’s mouth is latched to your dripping pussy. his tongue gives a few languid long licks before he dives right into for the main event- your clit.
once his lips wrap around your clit he’s eating like a man starved. suckling your clit into your mouth while using the tip of his tongue to lick at it, before he detaches from your clit to lick and taste you fully.
he’s whining, fingers digging into your thighs as his hips are grinding into nothing except air. your taste is addicting- and he’s sooo greedy while he’s eating because he doesn’t know where to go, should he torment your clit? lick your slit as a whole? tongue fuck your hole? he’s so overwhelmed and drunk off your taste that he doesn’t know so he’s messily eating at this point but it’s bringing enough pleasure to you that you’re whining and moaning so he’s doing it right.
your hands find purchase back into his hair, tugging slightly which again causes him to whine “fuuuck denki, s’good” you mewl.
he glances up at you through his lashes, his tongue and lips deciding to find their home on tormenting your clit for now while one of his hands move from your thigh to tease your entrance with his fingers.
your hips are grinding against his face at this point. moans leaving your lips freely as his lips and tongue assault your clit with pleasure.
a gasp leaves your lips when he slides two fingers deep inside of you while curling them. his large fingers reaching deep to rub that spongy spot inside of you that has you seeing stars.
your moans only grow louder, your pulling on denki’s hair growing sharper which in return makes him moan. “mmph!” he moans muffled from being buried between your thighs. his fingers start to move rhythmically and curled, determined to bring you more pleasure.
sticky sounds from denki’s licking and him fingering you fill the air along with your moans and whines. you glance down at denki, breath shaky as you feel that familiar coil in your tummy building tighter and faster than expected.
“m gonna mmph! cum” you announce as your hips continue to grind against his face, chasing your high.
determined to make you finish, denki’s pace of his fingers and tongue pick up, his curled fingers practically assaulting that spongy spot inside of you, causing your thighs to shake.
with a final thrust of his curled fingers and a final suck and lick, you cum, hard.
and denki continues lick at you, rocking his fingers in you to ride out your high before he pulls them out and cleans up all of what you have to offer after cumming before sucking his fingers clean like the greedy boy he is.
he stands up on his feet again, his hands braced on your thighs, just for him to be pulled down into a heated kiss by you. you can taste yourself on his lips.
the two of you pull away from the kiss. denki is panting, still trying to properly catch his breath after drowning himself in the taste of you so selfishly from being so addicted.
“chair” you speak, as you point to your desk chair. “and take your pants off”
he listens, of course. moving to the chair, right before he sits down he unbuckles his pants and lets them pool to his ankles and steps out of them. his hard on is soooo much more prominent now with the front stained from precum. his hands move to the waistband of his boxers, and he looks to you for the green light to take them off, when you nod, he strips of them too.
and god, he’s big. probably about seven and a half inches long- if not longer and at least two inches wide, all with the prettiest pink tip you’ve ever seen and veins that run along the shaft.
you move from off the desk to denki, straddling him. your thighs on either side of his as you can feel his heavy erection against your ass. his hands immediately find purchase on your hips as he looks at you with needy eyes.
“please” he speaks. “please i wanna be inside of you so bad” he practically pleads shamelessly.
you caress his jaw ever so gently, knowing you can’t say to such a cute plea like that.
“well of course, pretty boy” you speak as you align yourself with his cock before sinking down onto him.
the sound denki lets out is something you could only dream of a man making. years of experience yeah, but never have you ever had a man literally choke on air and shamelessly moan when all he’s doing is entering you.
once your flush against him, you waste no time in building a rhythm with your hips, first grinding against him to let him stretch you out before you go to bouncing on his cock.
denki’s head falls back against the chair as he whines and moans shamelessly. his hands that were once purchased on your hips now on your exposed boobs that are bouncing right in his face
“f-fuuuuck oh my mmph! god- you’re so tight-“ he moans. “bounce on my cock, use me, i don’t care just d-dont stop”
and you don’t, your moans mixing with his as you continue bouncing, his fingers roll your nipples as he tries to not become so pussy drunk.
but after a moment, he becomes insatiable for more, needing more, wanting to prove himself to you.
“c-can i fuck you- oh my god please?” he asks you through bleary eyes.
you nod as your bouncing slows to a grind and denki wastes absolutely no time in lifting you off until you’re standing, he turns you around and pushes you down onto the desk and wastes no time in pushing himself back into your warm sticky walls.
the position change with pleasure is so dizzying. the desk pushes against your tummy naturally so when denki bottoms out you can realllly feel him deep inside of you.
you can’t help the loud cry that escapes you at that feeling. and before you can comprehend anything, denki is moving- and his trusts are unforgiving.
he sets a heavy pace- his trusts not exactly fast but he’s definitely hitting hard. and he’s in a trance at how your ass recoils against him with every thrust. he can’t help but smack it.
you yelp at the sudden feel and clench- hard, causing him to chuckle with a grin. “ya like that, pretty girl?” he asks tauntingly.
okay was this or was this not just the same man who was looking at you like a puppy and sniffing your goddamn underwear?! why is he-
“cmon, don’t be shy now, answer me” he says with a fake pout in his voice.
you’re pulled out of your trance as he smacks your ass again, causing you to jolt slightly and moan. you nod your head in return before mewling a “yeah” that was meant to come out normally.
yeah. he was the same man who was just looking at you like a puppy and sniffing your underwear but right now you really don’t give a fuck about how you just handed him the power accidentally when his dick feels too good.
“f-faster denki” you cry out
denki picks up his pace at your request, his pace slowly climbing until it’s practically brutal and the only thing that fills the room is the plap! plap! plap! of skin to skin, his pants and moans, and your cries.
it’s erotic as hell, having sex in a hero agency- his hero agency. but neither of you are thinking of that right now. you’re only concern right now is the coil that’s causing your tummy to burn and how you’re genuinely getting dicked down probably the best you ever have.
“fuck you look so good like this princess” denki pants out. “should take a picture and make it my wallpaper or somethin’.”
one of his hands move from your hips down to in between your legs, easily finding your clit as he gives firm tight circles to it, causing you to bury your head in your arm and cry out as your legs start to shake.
denki chuckles at that reaction, his pace unfaltering “you’re taking my cock so well, you gonna cum princess?” denki asks with a grin plastered across his face.
you don’t even get to yes or no- your body decided his words were the green light to let go as you cry out his name rather loudly and your legs shake.
the way you squeeze denki so tightly pushes him to the edge too, with a loud whine yes whine he leans over your back and cums deep inside of you, his cock twitching inside of you.
the two of you stay like that for a moment, him laying over your back as you two pant and try to recover from the intensity of your highs.
“you okay?” he asks softly, moving hair from your face so he can see you.
you give a weak nod “mhm” you hum.
“good good” he says as he moves from leaning over, he pulls out and watches his seed fall from your ruined pussy to the floor. he plops into your chair and pulls you down with him to sit with him, his arms wrapped around you.
comfortable silence falls, the two of you still coming back to reality after the intensity you just shared- all before you break it.
“so that paperwork i was working on-“
