It was a bright morning, but the air in the Institute had that usual subtle tension that precedes a busy day. You had just finished a complex lesson on Quirk evolution and the most effective strategies to adopt in battle. Your mind was still pounding from the effort: a stubborn headache had been haunting you for days, and you had just swallowed a pill in a vain attempt to calm it.
In the teachers' lounge, the atmosphere was lighter. Midnight and Mt. Lady laughed heartily, exchanging sharp jokes under the amused gaze of the principal and the as-always-impassive gaze of Aizawa. You sank into a chair, the rustle of your jacket breaking the hum of the room for a moment. A deep breath, a moment of respite.
Your mind was racing that morning. Thoughts raced relentlessly, confused and noisy. You felt the need to talk to Katsuki again, to fully understand his true intentions. The last time you spoke, everything was suspended, like a sentence left unfinished.
So, during recess, you stopped him in the hallway. His gaze, as always, was impatient, ready to pounce. Without saying a word, you motioned for him to follow you. You led him to the terrace above the Institute, where the air was cooler and the noise of the distant classes seemed to fade into the wind.
"What do you have to tell me, sensei?" he asked, his gaze serious.
"What were you implying the last time you…?"
His eyes rested on your lips. "Exactly what I said."
"I mean…you'd be willing to…"
He nodded. "If you don't want an exclusive relationship…anything to have you near me."
You saw him clench his fists until they almost hurt, his knuckles whitening under the tension. You slowly approached, feeling your heartbeat accelerate as your eyes met. That spark of pride and anger still burned in his eyes, but you could see beyond it, glimpse the boy beneath the armor.
You gazed at him with that affection you couldn't show anyone else, a silent warmth that seemed to melt his stubborn armor for a moment. Katsuki initially looked back at you—just for a second. Then he snapped his eyes away, his cheeks slightly flushed.
"Tsk." He clicked his tongue, trying to hide his embarrassment. "When… when do we start?" he finally asked, his voice rough, seeking refuge in the first excuse that came to mind.
"Even tonight, if you're free. At my place. Are you up for it?" You brought a hand to his face.
He nodded and kissed your palm. "And who will be there?" He continued, visibly excited.
"I was thinking about asking Endeavour and Mt. Lady to start…"
"No," he replied categorically.
You looked at him, curious. "Why not?"
"I want that old bastard to be there."
You placed a hand on your hip. "He and…?"
"He and that bitch of Midnight sensei."
Your stomach tightened. Why those two? You wanted to say something, but the words died in your throat. You simply took a deep breath, trying to calm the knot in your chest. You had to grit your teeth and endure... you knew you'd already asked too much of Katsuki. You couldn't push yourself any further, not with him.
So, in the end, you decided to let him choose. It was the right thing to do, even though everything inside you was screaming otherwise.
"Okay, then, tonight at my house. At nine."
He approached you and grabbed your wrists. "Sure, but remember. You'll always be mine, and that's it."
***
That evening, your living room was bathed in a beautiful golden light from the scented candles. In the air, you could sense a sort of magnetic electricity, dense, charged with an expectation that seemed to vibrate between the beige walls, all accompanied by the sweet and enveloping scent of incense burning on the low table. You were sitting on the black leather couch, legs crossed, and your fingers were playing nervously with the hem of the too-big t-shirt you were wearing (Katsuki's, which hung on you like a second skin). The fabric barely touched the curve of your large, firm breasts, revealing the smooth skin of your thighs every time you moved. It felt like a silent invitation.
Katsuki stood beside you, his arms crossed over his broad chest, his muscles tense beneath the tight black T-shirt, which accentuated every curve of his body. He hadn't said anything yet, but his presence burned in the room, dominant, undeniable. You could feel the heat he radiated, that mix of strength, possession and nitroglycerin that made you tremble every time your eyes met. He didn't need to touch you to make you understand who was in charge. It was all there, in his red eyes, cold and burning at the same time, scrutinizing you as if he could read your every thought, your every intimate desire.
The doorbell rang, and the room filled with a sharp sound that startled you and made your heart skip a beat.
Katsuki didn't move. Not immediately. He remained still, his eyes following you everywhere, as if he wanted to make sure you didn't run away, that you didn't change your mind at the last moment. Then, slowly, he reached out and grabbed your chin as he always did, his fingers closing with just enough pressure to let you know it wasn't a request, but an order. "Are you ready to be my slave, my love?"
His voice was a whisper, a moan clogged your throat, and a shiver ran down your spine like a fiery caress. "Do whatever I order?" he continued.
You nodded, your breath catching in your throat. There were no words, there was no need to speak, really. Desire was consuming you, a fire blazing between your thighs, wet and insistent. You wanted this. You wanted them. You wanted to be used, shared, possessed until you couldn't remember your own name.
Katsuki smiled at you, his cruel grin making your stomach clench. "Good girl." Then he turned, his footsteps echoing down the hallway as he approached the door. You remained still where he'd left you, frozen in anticipation, your fingers gripping the sofa.
The door opened.
Toshinori and Midnight entered like a gust of warm summer wind, bringing with them a palpable air of tension mixed with lust, almost dangerous. Toshinori as usual, tall and sculpted, his blond hair tousled as if he'd just finished fucking someone against a wall, his jeans unzipped, revealing the line of his black boxers. Midnight, on the other hand, was wrapped in a blood-red silk dress that clung perfectly to every curve of her body, her lips painted the same shade, her blue eyes shining with mischief. Both were smiling, as if they already knew exactly what was going to happen that evening.
"Good evening, little flowers!" Midnight exclaimed, throwing herself at you. You returned the hug, smiling.
"Good evening to you…" you replied, in a polite tone. Katsuki approached the two of you, straightening his back.
"Uh, who do we have here? What a handsome hunk!" Midnight exclaimed, running a hand between Katsuki's legs.
At that moment, your heart stopped. Why were you feeling that way? Why were Midnight's hands on Katsuki's cock… bothering you so much?
You looked up at him. He'd already been staring at you for a while.
"You seem…impatient," Midnight said again, her voice a velvety whisper that seemed to envelop the room. Her eyes slid over you, assessing you, and you felt your face heat up. You already knew what they were seeing: a surrendered girl, ready to be taken, used, shared between them. Would that really have pleased you?
Katsuki pushed the sensei's hand away; she was becoming too intrusive. "There's no need to wait," he said, moving closer to you.
Your nipples instantly hardened as you saw him take a step toward you. Your pussy was throbbing, already nice and wet and open. Before you could take another breath, Katsuki was on top of you. With one hand, he grabbed your hair, pulling it back forcefully, forcing you to arch your back, exposing your throat. With his other hand, he ripped off your shirt in one violent motion, the buttons flying off as the fabric tore. You moaned, a guttural, desperate sound, as your lips parted in a gasp.
"I'll fuck you first." He growled, and you felt the couch buckle under his weight as he knelt between your legs. His fingers slid between your wet thighs, roughly ripping off your panties as well.
The cool air caressed your pussy, and you bit your lip to keep from screaming when you felt his fingers sink inside you, two, then three, then four, stretching you mercilessly.
"Holy shit, look how wet you are... look!" he murmured, satisfied. "You like it, huh? The idea of being used by us, huh?"
You nodded, about to say something, but your words got stuck in your throat, your body trembling as he penetrated you with his fingers.
Midnight and Toshinori were sitting on the couch, close together. They were both enjoying the show, masturbating each other. Toshinori had done nothing but stare at you since he'd walked in.
Then, without warning, Katsuki pulled out, leaving you empty, trembling, needy.
"Beg," Katsuki commanded, and you did so without hesitation.
"Please," you panted, "I need you. Inside me."
He didn't keep you waiting. He unzipped his pants with a brusque movement, his cock springing out, thick and hard, the tip already slick. You stared at him, mesmerized, your mouth opening in a moan as he grabbed your hips and pulled you toward him, sliding you to the edge of the couch.
"Bakugo, boy, you sure do have a way with women," Midnight announced, her voice sultry. She stood up, approached the two of you, and knelt down, right in front of his cock. You stared at her, incredulous, even slightly jealous. Then you looked at him.
Katsuki didn't let her suck it, he penetrated you in one violent thrust, filling you completely, drawing a cry that tore from your throat.
"Fuck!" he screamed, his fingers digging into your flesh as he began to move, his hips slamming against yours with a force that made you die inside. "God, you're so tight!"
Midnight was on top of Toshinori's cock, watching you two come. She licked her lips as Toshinori sucked her nipples.
In that moment, you realized that watching Toshinori fuck Midnight didn't bother you. In fact, quite the opposite... you liked it. But it would bother you if she touched or fucked Katsuki's cock. (This wasn't the time to think about those things.)
You could only moan as your body arched against his, your nails scraping his back, and he fucked you with deep, hard thrusts. Your pussy clenched around his eager cock, desperate to hold him, to make him cum, to be filled with his hot cum.
"More…" You moaned, your words coming out in hiccups. "Harder…my love…"
Katsuki stopped and looked into your eyes, surprised by that "my love" spoken so softly. As the two of you stood still, losing yourself in each other's eyes, Midnight began to moan, a sensual moan. "What happened? Come on, keep going!"
Katsuki smiled, then turned his head away. He grabbed your wrists with one hand while with the other he twisted one of your nipples, pinching it until tears came to your eyes. "You're my slut." He growled, increasing the pace of his thrusts, his hips pounding against yours with brutal force. The couch was creaking beneath you, your bodies pounding together in a wild rhythm as yours and Midnight's moans mingled, growing louder and louder, more desperate.
You were starting to feel the orgasm building inside you when Katsuki suddenly slowed, smiling.
"Absolutely not," he ordered, as he grabbed your throat and squeezed, just enough to cut off your breathing, to make black spots appear before your eyes. "Not yet. Not without my permission."
You gasped, your body unable to stay still as you held back your orgasm, the walls of your pussy clenching around him, desperate. Then, suddenly, Katsuki withdrew, leaving you empty inside, trembling. You moaned in frustration, your pussy throbbing, aching.
"All Might!" Katsuki exclaimed. A hint of sadness crossed his face. "Now it's your turn."
He didn't need to be asked again. Midnight moved off him. He stood, imposing, and approached you, his blue eyes shining with lust as he looked at you, stretched out on the couch, legs spread, your pussy glistening in his eyes. "Jesus…you're a vision," he murmured, his fingers penetrating your wet pussy, first one, then two, preparing you.
Out of the corner of your eye, you noticed Katsuki standing next to you. He was masturbating, his hand touching your breasts. "See that…" You didn't have time to finish your sentence and point to Midnight before he interrupted you. "No. That one sucks. And besides, you have to do what I say, so I'm staying here."
You moaned, arching against Toshinori's hand, desperate to be filled again. "Please," you begged, closing your eyes as you felt the tip of his cock press against you.
Toshinori didn't keep you waiting any longer. He entered you from behind in one powerful thrust. His hands gripped your hips with incredible force. You cried out, your body arching backward as he began to move. His thrusts were deep and steady, each thrust making you slide forward on the couch, forcing you to grip the cushions to keep from falling.
"You're… so beautiful, damn it. I miss you…" Toshinori panted, while Katsuki looked at you, aroused.
You couldn't respond for the second time. Toshinori was fucking you from behind, his balls pounding into you every time he slammed into you. But you felt a hand grab your hair, pulling it back forcefully, forcing you to arch your back and offer your breasts to Katsuki, who was quickly touching himself.
"Midnight-sensei," Katsuki thundered. "Come here. Show us what you can do with that mouth."
She didn't hesitate. She knelt before him, her red lips opening over his cock…
"Not to me, sensei! To her…I want you to lick her nipples."
Midnight looked up at him. "Why, don't you want me to suck you too?"
"No. I already have someone to suck my cock. I don't need you."
She nodded and stood up, moving closer to you. Her tongue wrapped around your nipple, she kissed it, she sucked it. You moaned at the sight of his mouth against you, as Toshinori continued to pound you from behind, his thrusts getting harder and deeper.
"Yes, like that..." Katsuki panted, after he'd reached up to caress your hair. "That's right, you're my slut, mine alone."
You could only stare, mesmerized, at Katsuki's beautiful, young face, which craved you more than anything. Your eyes were shining as Toshinori grabbed you by the hips and fucked you relentlessly.
"Can I…can I cum?" you asked him, your voice broken, desperate.
"No," Katsuki thundered, his eyes burning. "Wait. You'll have to cum on my cock."
You nodded, tears streaming from your eyes as you tried to hold back your second orgasm, your body shaking with the effort. Then, you felt Katsuki's fingers slide down your back, caressing you.
"Now, Midnight-sensei. Do you want her pussy? If so, come here."
She quickly rose from the couch and moved behind you, her hands grasping your butt, spreading them, while her warm, wet tongue slid along your slit, from pussy to asshole, licking, sucking, preparing you.
"Oh, my God…" you moaned. You were just moments away from orgasm when Katsuki ordered you both to step aside, as it was his turn again. Toshinori moved from behind you and went behind Midnight, continuing to fuck her violently.
Katsuki returned to your pussy, and you could feel him rock hard inside you.
"Ready to be filled, sensei?" Katsuki asked, and you nodded, desperate, as you felt his cock stir. After a couple of thrusts, he grabbed you by the hair, his body beginning to shake violently. He began to move faster and faster, with very deep thrusts, all while Midnight continued to lick your asshole and take Toshinori's cock from behind.
It had become too much. Too intense to bear. Pleasure suddenly overwhelmed you, you felt Katsuki's cock filling your pussy with cum, the sound of Toshinori pounding Midnight mercilessly, her tongue in your ass, and you were there, between them.
Toshinori came after you in Midnight's pussy, his thrusts becoming erratic as he emptied himself inside her. Then it was Midnight's turn, pulling away from your ass only to crawl in front of you, her fingers cupping your breasts as she cried out in pleasure.
When you all finally collapsed, you were breathless, sweating, your body covered in bite marks, scratches, and bruises, the irrefutable proof of what had happened. Katsuki stayed inside you a little longer, his face on yours, his breath in your nostrils. He was stroking your hair, while he looked into your eyes with an intensity you'd never seen before, almost tender.
"Do you…do you want to be my girlfriend, Tara?" he whispered in your ear.
You widened your eyes, too tired to speak, too overwhelmed by emotion to do anything but surrender to that truth. He loved you, unconditionally. In that silence, between you and him, you understood something: Toshinori was no longer the man you thought he was, and after that day, you had confirmation of it.
You also understood something else: that everything that had happened wasn't just about domination, sex, possession. It was something bigger, more dangerous.
Perhaps it was love. Or something very, very similar.
