Walking down the hallway with his hands in his pockets, Denji walks into you, quietly laughing. The two of you have been extra flirty today. Even though you're at work, you're both in such a lighthearted mood you can't seem to help yourselves. Bumping into each other and giggling, poking and prodding when your backs are turned, and stealing glances until one of you blushes and looks away.

Everyone has either been groaning at your public displays of affection, or silently thinking to themselves how cute it is… but neither of you take notice of anyone or anything else around in the midst of your flirting.

Makima called you both to her office to place you on an assignment together, since you've been partners lately. Before walking into her office, you and Denji try to stifle your laughter and walk in as seriously as you can without cracking a smile.

But once you enter, however, you find that Makima isn't there. Maybe she stepped out? Maybe she hasn't gotten there yet and the two of you are early.

You walk over to Makima's desk and hop on top of it, sitting at the edge.

“Hey, you can't just sit on her desk, I don't think Makima would like that." Denji suddenly says a bit more seriously. Swinging your legs, you raise an eyebrow at him.

“Oh yeah? What are you gonna do about it then?" You smirk. A grin forms in the corner of Denji's mouth as he tries to sternly walk up to you, slamming his hands onto the desk on both sides of you. Grinning, he leans forward over you slightly, causing you to lean back a little.

“Well, I could just tell her when she gets in…” Denji smiles to himself and then chuckles under his breath when he gets an idea. “But if you can find a way to silence me, I guess I won't be able to tell her." Denji smiles coyly at you.

You feel your face blush when you realize what he's asking for. You and Denji have kissed a few times already, sure. But they were always quick ones since both of you always ended up being too bashful to really go in for a real kiss yet. That, and you've never really had enough privacy to really go at it.

Denji places his hand in the small of your back, eyes narrowing as his face suddenly becomes serious, looking down at your lips lustfully. You've never seen Denji look at you like this so closely before, and it made your heart race. Maybe it was the constant flirting today, or maybe it was seeing him in uniform that really did it for you, but you can't seem to control your urges today, either.

Denji gently pulls your body towards him, slowly leaning in towards you, waiting for you to close the very small gap that he's left between your panting lips. Instinctively running your fingers through his hair to grab his head, you pull yourself forward the rest of the way and kiss him deeply. Almost immediately do you feel Denji start breathing harder and more haphazardly, kissing you back deeper than he ever has. His kisses come quickly as if he can't get enough of them, grabbing your face now as well to be able to pull you even the tiniest bit closer to him.

You momentarily break, foreheads against each other's, panting. Your heart is still racing… you've been waiting for so long now to really kiss Denji like that. You've been fantasizing about a lot more than that, to be honest, but this kiss was an incredible start. It was much more passionate than you expected from him.

You look down and notice that subconsciously, you've wrapped your legs around Denji's waist as you remain seated on the desk. Following your gaze, Denji sees that you've wrapped yourself around him, and he presses himself against you. You feel his bulge, but your thoughts are quickly redirected to him now dragging his finger down your cheek… along your jaw to your chin, still panting closely against your lips.

“Do you wanna finish this back home?” Denji leans forward to whisper into your ear, his hot breath making you cringe with pleasure. His cheek rubs against yours like animals nuzzling each other.

“We can't just leave though…” you think out loud. "Makima hasn't seen us yet, but literally everyone else has. They'll tell her we just left-”

"I can't, I…" Denji starts squirming. “I need you. Right now." Denji whines through gritted teeth. He's been rubbing against you this whole time, growing harder and harder. “I have to do something about this." He grabs your hand and puts it over his crotch. It startles you for him to suddenly do that so forwardly, but you quickly understand why. He is as hard as a fucking rock. Your face reddens as you look back up at him, pulling your hand away.

“But Denji, we haven't… I mean, isn't this kind of fast?” You say that, even though it's not really how you feel. You were just thinking to yourself how you've been fantasizing about doing this exact kind of thing with Denji. Although, you did expect the setting to be a little different.

“You don't want to?" Denji asks somewhat surprised and disappointed, almost pouting at you. He lets up a little bit on grinding against you in response.

“No, I do, but…” you blush as you realize you've just admitted it out loud. At this point there's no reason to really be bashful anymore. "I just thought it would have happened a little differently than this. A little more… romantic I guess?”

Denji looks somewhat disappointed and admits that he had hoped for the same thing and apologizes.

"I kind of had something planned that was nicer than this, but…” he sighs. "It's kind of hard when we're never alone. At home you share a room with Power and Aki is always there. Otherwise we're always here. I just thought maybe since everyone's at work right now, nobody would be home.”

You lift Denji's face to kiss him and smile.

“I just can't say no to you, Denji." You chuckle. You were head over heels for him, so it's true that you didn't want to ever say no to him. You had no reason to say no to anything, especially since you really did want to go all the way with him.

You both start kissing heavily with Denji grinding against you again, until you hear footsteps and muffled voices slowly approaching the office.

With your legs still wrapped around him, Denji lifts you off the desk and carries you into the closet in Makima's office.

“Why are we hiding in here??“ you shout with a whispered voice. Denji tilts his head at you as if the answer should be obvious. He takes your hand and once again places it over his crotch, where you feel how incredibly hard he is. It's true, there's no way he would be able to face Makima with a freaking tent in his pants.

Makima enters her office with Aki, the two of them chatting quietly and sitting by her desk. You hear her say that she thought you would both be waiting for her, but maybe you didn't come yet.

You realize now that your hand is still on Denji's crotch and he's been rubbing up against it. You feel wetness start to pool between your legs at the prospect of hiding in a closet with an extremely horny and hard Denji.

While you try to peek out of the slots of the closet doors, Denji's body presses up against you from behind, grinding up against you. He kisses the nape of your neck, delicately nilbbling on it with his sharp teeth. You breathe in sharply and turn around to continue kissing him. At one point Denji breaks away to put a finger up to his mouth, indicating you both need to be quiet. You nod quickly, and get back to kissing him.

Both of your hands have been roaming around each other's bodies, feeling and grabbing at each other. Denji's hand found its way up your shirt, not surprisingly, and has been fondling your breast. You managed to unbutton his pants in the dark and have been stroking Denji's cock as he buried his face into your neck in an attempt to keep quiet. Honestly it all happened so quickly that you can barely recall who started what, but in the heat of the moment you lost yourself to your lust.

You knew you both should have stayed still in the closet, but you felt so intoxicated by the thrill of the situation. Denji starts impatiently thrusting in and out of your hand, turning you on and making him shake impatiently. The lack of air circulation makes you both start sweating and panting more. The feeling of Denji's (surprisingly soft) fingers caressing your breast, fingertips circling around your nipple, makes your head spin. Between that and feeling his cock throbbing in your hand was enough to make you want to have your way with Denji right then and there.

He must have felt the same way, because suddenly, you feel him whispering in your ear from behind.

“I can't take it anymore, I want to be inside you, please…” you feel Denji sighing with frustration on your neck, face down against your skin. Your heart skips a beat hearing him want the same thing as you, but reality begins to set in a little bit. You're still in Makima’s office, her and Aki just across the room. You have a feeling Makima could tell that you two were in there, but she didn't seem to acknowledge the closet or look that way yet. She could come in here at any moment, for any reason.

“Denji, we can't," you say with disappointment. You swallow hard, hearing yourself say something you don't really believe. “Makima could hear us, it's too risky."

You hear Denji quietly whimper into your neck, and you can feel his body trembling pressed up against yours from behind. He starts kissing your neck pleadingly, working his way up from the nape of your neck to your ear. He nuzzles it with his nose, panting desperately, swallowing hard. He licks the shell of your ear slowly, nibbling on it with his sharp teeth and whispering “please" over and over in an attempt to turn you on more and change your mind.

“Please, I'll do anything, I'll make it up to you. Next time I'll make it super romantic, I just…” Denji holds back a grunt to try and keep quiet. “I'm getting close. I don't wanna make a mess or Makima will know we were in here. Please let me cum inside you, I can't take it anymore." Denji whimpers again. "It's gonna happen soon, please, let me finish inside of you and I'll do whatever you want after this. Please…”

Denji has been helplessly thrusting in and out of your hand this whole time, knees buckling every now and then at the desperation of wanting to fuck you. Just hearing him beg you like this made you so wet that you could feel it seeping through your underwear… your clit swelling at the thought of finally having Denji inside of you.

As soon as you start undoing your pants, Denji showers your neck with kisses, licking and sucking at your exposed shoulder in appreciation. When your underwear falls to your ankles, you feel wetness being dragged down your thigh and leg with it. No sooner than when it hits the ground do you feel Denji lining up to enter you, his engorged head wading in your pool of wetness.

However, taking you by surprise, he pauses.

You feel Denji embrace you with both arms, pulling you into a hug from behind.

“I'll be careful, but tell me if it hurts." Denji whispers. If it hurts? ‘Why would it hurt?’ you think to yourself. Before you can finish your thought, you feel Denji's hand cover your mouth.

He slides into you, the length of him making you gasp. He must have known that would happen which is why he preemptively covered your mouth. Denji has to bury his face into your neck to muffle his “fuck". You feel him throbbing inside you, pressing against all your sensitive spots just right.

Denji slowly thrusts in and out of you. Slowly, because you're so incredibly wet that him moving in and out makes too much noise. But it's no use, he can't control himself any more and picks up the pace. You can't believe how big Denji is, his cock absolutely filling your insides and hitting further back than you imagined it would.

Through the slots of the closet door, you suddenly see more Public Safety hunters coming into Makima's office. You're somewhat relieved for the increase in noise because it's masking the squelching of Denji pumping in and out of you relentlessly. Your eyes keep rolling back cause Denji feels so fucking good, but you try your best to focus on what's going on outside. You can hear the other hunters asking where you and Denji are, and Makima say she's been waiting for the two of you.

You are again distracted when you feel your wetness dripping down your thighs.

“You're so wet," Denji whispers through gritted teeth, trying so, so hard to keep quiet. “You feel so fucking good. Am I hurting you? Is it too deep…” Denji's voice trails off as he pulls out of you, slowly pushing just the head of his cock in and out of your entrance teasingly. "You like that…" Denji purrs while licking your ear. You feel like a faucet with how much wetness is just pouring out of you at this point. You can practically feel your creaminess has gotten on Denji's lower abs, nearly stringing every time he pulls away.

Denji must be getting close because you can feel how engorged he's become inside of you, his head practically getting stuck halfway each time he pulls out. His grip on your body has gotten tighter, and you can feel his hands shaking in desperation. He's trying so hard to just finish while fighting the urge to make it last longer.

“Getting… close…” he almost chokes on his words. He pulls your body tight against his chest, pumping in and out of you even faster now to put himself over the edge.

"Ahh~” Denji accidentally lets a slight moan out. Nobody seems to have heard, but you immediately see Makima's eyes dart to look directly at the closet as she sits at her desk. Unmoving, unchanged, she looks back to the group as they all try to surmise where you two could have possibly gone.

“Cum- cumming…” Denji manages to say between pants, “I'm cumming…” he whispers so quietly into your ear that you barely hear it.

Makima suddenly stands up and says the two of you must have gone home, and dismisses the Public Safety hunters. They all start walking to leave Makima's office, all passing right in front of the closet door.

Denji nearly slams his hand over your mouth again, and his own with his other hand, as he starts shooting inside of you. You can feel it spurting out of him as he twitches with each spurt. It feels so hot inside you, and so deep. Denji's body nearly convulses as he finishes inside of you, letting out a heavy breath through his nose with each pump, each twitch of his body.

Your heart is beating so loud that you can't help but feel like Makima can somehow hear it. That she's known about you and Denji being there the whole time.

Finally Denji takes a long, deep breath out, signaling the end of his (surprisingly long) orgasm.

Right away, Denji pulls you into a hug from behind and starts kissing your neck slowly and passionately. His hot breath on your ear makes you pulsate and clench inside, in turn making him throb against your insides. After pulling out slowly and carefully to make sure nothing spills out, Denji leans down to help pull your underwear and pants back up.

Makima tells Aki he should leave as well and see if we've gone back home. Makima walks him to the door, the both of them passing in front of the closet on their way. Makima then thinks to herself out loud that maybe you two have gotten distracted somewhere in the building and announces that she'll be going to look for you. You can't tell if she's actually saying this to someone outside the door that you can't see, or if she's saying it for you.

Either way, Makima does eventually leave as well.

Office now empty, you and Denji burst out of the closet, nearly tripping over each other. You realize how hot it was in the closet because the office is so much colder in comparison. Denji's face is beet red and glistening from sweat, and you imagine that yours must be as well.

Trying to quickly fix up your uniforms and straighten yourselves out, you and Denji try to leave the office when Makima pivots and appears in the doorway.

“Oh, it's you two. I almost sent out a search party for you. Do you care to explain?"

You suddenly feel Denji's cum trickling down inside of you, and in response you clench to keep it from coming out.

“We were late, so…” Denji's eyes dart around the room as he tries to come up with an excuse. “So we ran here! That's why we're so sweaty. Yeah, we ran. Sorry ‘bout being late miss Makima.”

“Well, you're here now. Come to my desk and I'll fill you in on your assignment.” Makima motions for you two to follow her back to her desk. Standing there while she explains her assignment for you, all you can focus on is keeping Denji's cum inside of you. You can already feel that your underwear and pants are soaked through from being so wet… as long as you didn't take long strides or sit down, nobody would be able to see it. But if all of Denji's cum came out as well… it might eventually show through somewhere.

After about ten minutes of standing and listening, Makima dismisses you both. You head to one of the cars to drive you and Denji to your destination, and when you get inside and shut the doors, you both sigh heavy and loud with relief.

“I'm gonna be honest, I have no idea what Makima asked us to do," Denji laughs, leaning back in the passenger seat with his hands behind his head. He glances over at you suggestively. “All I could think about is how my cum is still inside you." He smirks devilishly, eyes darkening with mischievous lust.

“How about we drive somewhere secluded and have a car quickie? That cum inside you would be great lube…” Denji laughs, somewhat jokingly but with an air of seriousness to it.

Your cheeks turn bright red as you look back at him and playfully smack his shoulder.

“But you…” you hesitate, becoming shy for some reason even though you and Denji basically fucked in a room full of people. "You said the next time will be romantic…”

Denji's face turns red as he also becomes shy for some reason. Without looking at you, he reaches over and takes your hand, his fingers lacing with yours.

“Yeah,” Denji smiles and chuckles. "It will be, I promise.”

"Why are you laughing?” You turn to Denji to see him holding tissues out to you. You take the tissues and try to discreetly clean yourself up so that people outside don't notice. When you're done, Denji puts his arm around your shoulder, dragging his finger along your cheek. You see his sharp teeth showing through his devious grin.

“Because I promise next time you'll cum with me.”
