Work Text:
Katsuki almost never texts you, preferring just to call and get to the point, but if he does something is very very wrong. So when you received a message in the middle of the day with his location and a message that read “Come here now,” panic flooded your veins. But wait, you recognize that part of the map. The map marker rested squarely on top of his agency. You left your office in a hurry, still dressed in the skirt and button up shirt that was your workday attire and made your way across town as fast as you could. When you pushed open the doors to the reception area of his agency it’s obvious there’s a problem. The receptionist won’t even make eye contact with you when she speaks. “He’s in his office.”
You scurry down the hall and don’t even bother knocking. He summoned you here after all. He was sitting at his desk straight backed, with that permanent scowl plastered on his face. “Took you long enough.”
Unbothered by the typical gruffness you stood in front of his desk, though an undercurrent of anxiety swept through you. “What’s wrong?”
He pushed back from the desk and one thing was very obvious. He was hard, almost certainly uncomfortably so, judging from the look on his face. “I need help. No matter what I do this will not go away.”
You wanted to laugh but knew the second he even thought you were laughing at him he’d explode, maybe literally. “And you’ve tried to just… you know.” You move your hand in the universal sign for jerking off. A smirk was threatening to tug at the corner of your mouth.
He stares daggers at you. “Three times.” At that, any semblance of humor in the situation died away.
You bit your lip in thought. “Get hit by a quirk?”
He stared. “What the hell do you think, woman?”
“Do you know anything about it? Did the villain tell the police anything? Maybe it’s like you have to fuck your one true love or whatever?” He could see the wheels turning in your head and knew that if you didn’t stop now, you’d just keep talking.
“Are you going to keep babbling or are you going to shut the fuck up and help me?”
You sashay around the desk, dropping to your knees in front of him. “What do I get in return?” Your fingers tug the material down slowly as his hips lift off the chair.
“The best cock you’ve ever had, that’s what.”
His arrogance would be his downfall, you decided. You took his length in your hand and barely flicked your tongue against the head. You looked up as innocently as you could manage.
A growl rumbled through him as he threaded his hand through your hair. “If you're here to help then do it right.”
You pulled back completely, resting your hands on his thighs, face schooled into a careful neutral expression. “You're the one who demanded that I come here. Who are you to tell me I’m doing it wrong?”
Katsuki yanked you off the floor and shoved you onto the desk. He flipped your skirt up and ripped the crotch of your panties open. He held two fingers up to your mouth and shoved them in when you gasped. “Suck.” You did as he asked, too shocked by the sudden change in position to disobey, even swirling your tongue around the pads of his fingers. “Was that so fucking hard?” His fingers circled your entrance, pleased to find that you were practically dripping already. “Such a slut for me, aren't you princess?” You nodded hastily, trying to reach forward to press your lips to his. “I want to hear you say it. What are you?”
A shaky moan escaped you as he brought his fingers to you clit. “I'm your slut, Katsuki.”
He circled around the nub and held his cock in the other hand. “What do you want?” You knew he always got off on holding out on you and it seemed, horny quirk or not, that it was still the case.
You head dropped to his chest and your hands wrapped around his biceps. “Fuck me.” Another lurid mean left your lips as his fingers danced through your folds. “I want you.”
He sheathed himself it one thrust, watching your eyes flutter shut. It was his favorite part, watching you fall apart because of him. His hands grabbed your ass to pull you closer to the edge of the desk, while his hips pounded you at a brutal pace.
Katsuki’s hand slipped between your bodies and you felt release coming quickly. A needy whine spilled out. “Kat-” He hushed you with a kiss, nothing more than teeth and tongue.
“I know princess. Let go.” Your eyes closed and hands squeezed his arms
He was right there at the edge with you and as soon as he felt your core clench around him, the pro hero growled and pulled your body almost impossibly closer, riding out his release. He opened his eyes first and pulled out slowly, mercifully softening.
Your fingers come up to trace the lines of his jaw. “Better now?”
His vermilion eyes fluttered open as his forehead came to rest against yours. “Yeah.” He slanted his lips against yours in a rare moment of tenderness before pulling away completely to fix his hero costume.
He handed you a box of tissues to clean yourself up with. “We need a non-emergency message system. I thought you were dying when I got your text. Maybe use an emoji or something next time.”
“Over my dead body.”
“You got hit by a quirk, doesn’t that mean you should get to take the rest of the day off?” A sly smile graced your lips as you righted your own clothes.
He scoffed. “Hell no, what kind of agency do you think I run?”
