He yanked you away from the wall with a force that made you stagger, his fingers still wet with your juices, and without a word he dragged you around the corner, towards a half-open door that led to a dark storage room, crammed with boxes and abandoned equipment. It wasn't a safe place. It was a perfect place. Because if anyone had come in, they would have seen you. They would have heard you. And that possibility, that risk, was like gasoline on the fire already blazing between you two.
As soon as the door closed behind you, Katsuki pushed you against the concrete wall, his body pressed against yours, his hand back on your throat with a pressure that made your head spin. "Now shut up, sensei. And take everything I give you."
He didn't even give you time to respond.
With a sudden movement, he lifted the skirt of your dress up to your waist, ripping your panties off with a tearing sound. "You won't need them anymore," he muttered, throwing the torn lace to the floor. Then his fingers were on you again, plunging into your pussy with a force that made your back arch. "God, you're so fucking horny." He gasped, his fingers moving inside you in sharp thrusts, his thumb rubbing your clit in ever-faster circles.
You couldn't help but moan, your nails digging into his shoulders, your hips moving uncontrollably against his hand. "K-Katsuki…"
"Shut up." His voice was a precise command. "Or do you want that old man to hear what a slut you are who can't live without my cock inside you?"
The mere thought made you twitch around his two fingers, pleasure rising up your spine like a hot wave. "Please…"
"Please what?" His fingers stopped, leaving you trembling and desperate. "Tell me what you want, sensei, or would you rather I make you scream?"
You looked at him with shining eyes in the darkness, your lips swollen and wet with saliva. "I want your cock." You whispered, your voice breaking. "Now. Inside me. Before anyone finds us."
Katsuki didn't need any more words.
With a swift movement, he unzipped his pants, freeing his already hard, throbbing cock, the wet tip of precum glistening in the dim light. He wasted no time. There were no caresses, no preparations. Grabbing your hip with one hand, he lifted you almost off the ground, forcing you to wrap your legs around him, while he positioned his other hand against your entrance.
Then he penetrated you.
One thrust. Deep. Brutal.
You choked out a cry against his shoulder, your nails digging into his flesh through his shirt as Katsuki filled you up in one motion, his cock easing its way into you with an ease that made you blush. "You're such a whore." He growled, teeth clenched as he began to move, his hips crashing into yours with sharp thrusts, sending you slamming into the wall with each thrust.
There was no sweetness, no tenderness. There was only the sound of your wet pussy squirting against his body, the sound of your labored breathing, the moans that escaped you every time he hit that spot inside you that made you feel like hell. "Katsuki!!"
"SHHH!" His hand returned to your throat, squeezing just enough to knock the breath out of you, while his other hand cupped your breast, pinching one nipple through your dress with a harshness that made your back arch. "Don't make any noise, slut. I want to see if you can come with my hand on your mouth."
The thought made you clench around him, the walls of your pussy squeezing around his cock in a massage that made him moan. "Tsk, damn it," he cursed, picking up the pace, his thrusts becoming more and more violent, sweat breaking out on his forehead. "What a bitch you are, sensei. And I'm fucking crazy about you."
You couldn't deny it. Not when every thrust brought you closer to the edge, not when you felt his cock swell even more inside you, not when the pleasure burned through your veins like liquid fire. "I'm going to—!"
"Cum," he commanded, with a growl of pure passion. "Now. On my cock."
And you obeyed.
The orgasm overwhelmed you, your legs began to tremble, your nails tore at his skin, while your pussy tightened even more.
"Fuck…fuck…!" Katsuki dug his fingers into your hips, holding you still as he thrust into you one last time, you felt his cock throbbing, the heat of his cum filling you, marking you.
For a long moment, you stayed like that: him still inside you, both of you panting, your bodies drenched in sweat, your heart pounding. Katsuki pulled out slowly, leaving you empty and trembling, your thighs still shaking from the aftershocks of your orgasm.
"Fuck," he panted, running a hand through your sweaty hair: "I…I love you, sensei."
You couldn't respond. You were too busy trying to catch your breath, your body still shaking and your mind clouded by adrenaline. It was then that something came closer.
A step.
Close.
Too close.
Katsuki stiffened, his eyes widening in the darkness, as you hurriedly adjusted your skirt, your hands shaking as you tried to cover the wet spot between your thighs. There was no time to clean yourself. There was no time to do anything. The doorknob creaked.
"Shit!" Katsuki hissed, grabbing your wrist and dragging you toward the darkest corner of the closet, behind a pile of dusty boxes. It wasn't a hiding place, it was a trap! In that moment, with his cum dripping down your thighs and the taste of him on your tongue, you realized something.
You didn't care.
In fact, the thought that someone might find you, that someone might discover how much you were willing to humiliate yourself just to have his hands on you, made you tighten your thighs, desire pulsing between your legs again like a second orgasm.
The door opened.
A figure stood out in the opening, the hallway light casting a rectangle on the dusty floor. "Oh my God, sorry! I didn't know anyone was here!"
The voice was female. You recognized it immediately: it was Midnight.
Katsuki didn't move. He didn't speak. He remained still, his body tense like a spring, while you felt his heart pounding in your temples. Then, slowly, the figure retreated, the door closed with a click.
Silence.
For a long moment, neither of you spoke. Katsuki then exhaled, a humorless laugh escaping his lips. "Holy shit." He ran a hand over his face. "We almost got caught."
You looked at him, your eyes still wide with excitement, your lips swollen. "It didn't happen, though. That just makes it…better."
Katsuki stared at you. Then, a small smile curved his lips. "You're sick, sensei," he said, his voice low. "You know that, right?"
You smiled, your fingers trailing down his chest, feeling his still-rapid heartbeat. "And you love me for that, right?" you replied before pulling him towards you for another kiss, slow, deep, vowing to yourself that this wouldn't be the last time.
Not that night.
Never.
***
You were at home that evening. You'd just finished showering and tidying up the house when you got hungry and started preparing something. Steam rose from the pot on the stove, the tomato sauce inside was bubbling, and it all enveloped the kitchen in a warm fog that mingled with the smell of the sauce. Your fingers gripped the wooden spoon with excessive force, as if that gesture could crush the tension that was clenching your stomach.
You were home alone. Katsuki was at U.A. practice and would be heading back to his place around 10. Suddenly, however, your phone rang. The loud ringtone of your new phone made you jump. You immediately wondered who it could be. Maybe Katsuki finished early, you thought. But the name you saw on the screen made your eyes burn: it was Toshinori.
You took a deep breath, your chest rising and falling beneath your tight shirt, still damp with sweat from the shower. You didn't feel like answering at all. Not right now. Not after what had happened with Katsuki a few hours earlier, at the institute.
But the phone kept ringing, insistently.
With a brusque gesture, you grabbed the device and pressed the green button. "Hello?" Your voice came out hoarse, choked by something that wasn't just embarrassment, but you couldn't quite define what else it could be.
"Hello." Toshinori's voice was warm, enveloping, and confident, as always. But there was something different that evening, perhaps a new concern that wasn't his, but yours.
"Sorry to bother you at this hour… are you busy?"
You looked back at the pot, where the pasta was starting to stick. "Yes. But nothing major." You bit your lip, hating yourself for not hanging up already. You weren't a little girl anymore. You were a woman, damn it. A woman who had just had one of the most intense orgasms of her life, her thighs still aching from the way Katsuki had forced you open, to take every inch of his cock as if it were the last time.
"Are you okay?" he asked, and you pictured his face, with that tight smile, the one that crinkled his eyes when he was genuinely worried.
"Of course." You replied, but you sensed that wasn't quite the case. "Why wouldn't be?"
There was a silence. Then. "I'd like to see you."
The spoon slipped from your hand, falling into the sink with a metallic clang. "W-what?"
"I need to talk to you. It's important." His voice was firm, but not too authoritative. It wasn't like Katsuki's, who always ordered you to kneel in a tone that brooked no argument. No, Toshinori demanded. And that, somehow, scared you even more.
"Tomorrow evening," he continued, as if sensing your hesitation. "I'll pick you up at eight. Is that okay?"
Your fingers were shaking. "I don't know if…"
"Please." A pause. "That's no small request. I know you have your own life, but… I need to see you. Really."
Your heart pounded against your ribs. God, why now? "Okay," you whispered, before he could stop you. "Eight o'clock."
"Thank you." The relief in his voice was tangible. "See you tomorrow, then."
You hung up. You remained there in the kitchen, phone still in your hands, breathing shallowly. What am I doing? Katsuki had just told you he loved you. That he wanted something serious. And what had you done? You had said yes to Toshinori. The past had come knocking on your door again just when everything was about to crumble, or solidify... you didn't even know.
With a simple gesture, you turned off the heat under the pot. Dinner was ruined. You weren't hungry anymore.
At 10 o'clock sharp, right after practice, like clockwork, Katsuki called you. "Yes?"
"Hey..." he said, his voice tense. "What are you doing?"
You closed your eyes. "Nothing special. But I need to talk to you."
There was silence. Then, a low growl. "About what?"
It didn't sound like a question, but an order. Just tell me what the fuck you want.
"Tosh… I mean, All Might, he called me." The words came out unfiltered. "He wants to see me tomorrow, I said yes."
The silence that followed was so thick, for a moment you thought the call had ended.
"WHAAAT?"
His voice was thunder. You recoiled, as if you could dodge his wrath through the screen. "Katsuki, please, listen…"
"So it's true." His laugh was bitter, cutting. "You're already tired of me, huh? You're going back to your old shit…"
"NO!" you cried, tears stinging your eyes. "That's not true! I haven't done anything with him lately… It's been a long time since…"
"Not YET!" His voice was icy. "But you will, right? That's why when I told you I loved you, you didn't answer. So you could run away with him without guilt."
"Katsuki, please, it's not…"
"Fuck you."
The call ended.
You stood there, the phone shaking in your hand, the black screen reflecting your shocked face… God, God, no!
