That morning, the students in 1-A, including your Katsuki, left for a twinning trip to another school. The U.A. hallway, which usually buzzed with voices, shouts, laughter, and quick footsteps, was unusually quiet that day. You stroked your belly; it was almost impossible to hide now, and every day you reminded yourself of how real it all was: your life, your choice. Him. Katsuki.
By now, everyone knew about your health condition and your relationship with him. The principal had accepted it willingly and allowed you to work anyway, especially while sitting, without straining. (News, as we know, always travels fast.)
You'd just entered the teachers' lounge when the girls you knew (Midnight and Mt. Lady) greeted you warmly with a hug and several kisses on the cheek, including a few caresses on your growing belly. Toshinori was sitting off to the side, his head resting on his hands as he read newspaper articles discussing who was the next strongest hero after him. As soon as he saw you, he smiled and winked. Your stomach tightened when you realized he was wearing that tight shirt you loved so much, the one that showed off his sculpted muscles and muscular neck. For a moment, you remembered when he used to fuck you a while ago, pounding you hard from behind until you screamed with pleasure.
After a few laughs and a few too many jokes, you turned back, determined for the first time to explore the institute's library. You descended a series of stairs until you reached the ground floor. That day, an incredible silence reigned. You took a deep breath, thinking you could finally relax a little.
You entered, and for a moment, your breath caught. Before you lay a sea of towering bookshelves, seemingly touching the ceiling. The ancient wooden floor creaked under your footsteps, while the air smelled of paper and dust. Along the walls, large oak tables stood next to bookcases, ready to welcome those seeking a place to study or lose themselves among the older tomes.
After a long look at the various books and files in the room, you chose one and sat down, moving your chair to the table directly in front of you. You'd just tidied up a pile of files when you heard determined footsteps approaching. A cheerful, youthful, and energetic voice broke the silence:
"Good morning! Oh...I didn't mean to disturb you. I thought there was no one here!"
You turned, surprised by his energetic and cheerful tone. Before you was a tall, blond-haired boy with a bright gaze, smiling sweetly. He wore his hero's uniform with a casual air, his hands tucked into his pockets, and his posture was so open it almost disarmed.
"Good morning," you replied, giving a polite smile. "No problem. I'm just finishing up some work."
"Oh, so you're the new teacher! Shimura, right? I'm Mirio Togata, nice to meet you. I've been told you teach strategy and tactics, right? Congratulations on your courage...it's not an easy subject, even for us veterans."
He laughed heartily, that hearty laugh that seemed to fill the entire room.
"Nice to meet you, Mirio. Yes, I started a few months ago now. I didn't think anyone would remember my name so quickly, though."
"How could I forget?" he replied, his tone slightly ironic but kind. "Everyone's talking about the new teacher who even managed to keep Bakugo in line. She must have some special powers."
You burst out laughing, surprised. "Oh, I just talk a lot and shout a little. It's a secret technique."
"It definitely works," he replied, tilting his head slightly. His gaze, however, remained fixed on your face longer than necessary. It wasn't intrusive, but direct...as if he were trying to decipher something he didn't yet understand.
You felt yourself blushing, and to cover your embarrassment, you returned to your files. "Are you always this… sociable with new teachers?"
"Only with the ones who seem interesting," he replied with an innocent smile. Then he added, more softly, "And you are quite the same."
You didn't immediately find an answer. You simply lowered your gaze and thought that perhaps there was something about him that was disconcerting you, probably a sincerity without malice... you thought.
"Well, thank you, Mirio-san."
He nodded, and silence returned for a moment. Then he walked away, leaning against a shelf across the room, his arms folded over his broad chest, muscles tense beneath his hero's uniform, the fabric so tight it revealed every vein beneath his skin. His eyes were intent on searching for something among those piles of books and essays on Quirks, but when you looked up at him again, his blue eyes were fixed on you, with an intensity that made your skin crawl. A sweet smile curved his lips.
Unconsciously, you bit your lower lip, trying to focus on the open book in front of you, but the letters seemed to dance across the page. Where's Katsuki? you wondered for what felt like the hundredth time. Your partner, the one you'd only recently begun sharing an apartment with, was gone. And now you were alone, in the library. With him.
Mirio had just chosen a book to read when he quickly pushed himself off the shelf and began to approach, slowly. You remained seated, legs crossed, your tight skirt rising just above the knee, revealing a hint of soft, rounded thigh.
"Anyway...there aren't many teachers who work late here. It's not safe, you know? I mean...with a big belly..." His voice was low, with that slight northern accent. He stopped a meter away from you, close enough for you to smell his sweet shampoo.
You looked up, feigning indifference. "Don't worry, Mirio. And besides, who would bother me in here?"
He smiled with that sweet look, which lit up his face. "Oh, I don't know. Maybe someone who can't resist the temptation… to grab you and do something to you while your partner's away."
The way he said that word made you jump. "Are you…are you trying to scare me, Togata-san?" you asked, closing the book with a snap. Your fingers trembled slightly.
He shook his head, his gaze hardening slightly. "Oh, no! I'm just saying…" He leaned in, bringing his face close to yours, so close that you could see his short, golden lashes in his irises. "If I wanted to hurt you, I would have already done it."
You moved away from his face slightly; he was too close. You swallowed, feeling your heartbeat pounding in your ears. "And instead… what do you want, then?"
He straightened his back, raising his arms in surrender. "Nothing, nothing, don't worry." He laughed. "I didn't mean to…sorry, sensei."
You smiled back, trying to compose yourself. After all, he was a good guy, there was no reason to think otherwise. Okay, I want to trust him, you told yourself. You sat back down, and Mirio moved toward you with easy confidence, dragging a chair before sitting across from you, as if you'd known each other forever.
"Is it okay if I sit here and read? I promise I won't bother you."
You raised an arm, shaking your head. "Of course. Don't worry."
He sat down across from you, still looking at you. "No one told me the new teacher was so beautiful…and sexy. If I'd known before, I definitely would have gotten in touch."
You glanced at him sideways, barely holding back a smile. His gaze was intense but not invasive, a blend of confidence and genuine curiosity. He wasn't trying to impress, he was having fun, and the best part was that you were too.
"But what do you think you're going to achieve, Mr. Togata, with this tried-and-true technique?" You smiled faintly.
"A conversation that doesn't want to end too soon," he replied, tilting his head slightly, his eyes fixed on yours.
"Yes, but you know that I…" You stood up and showed him your belly.
"Yes, yes, I know everything. I even know who the father is. I'm not trying to take anything away from you. Just to remind you that someone out there finds you fascinating. That's all."
You were silent for a moment. "You're dangerous, Mirio-san."
***
You'd just come back from the library, and you had an incredible headache. Pregnancy nausea had started to kick in again, and you just wanted to go home and lie down for a bit, perhaps after a nice hot bath. But you felt your skin tingling, a restlessness you couldn't explain. You stopped in front of the empty staff room door, your fingers grazing the handle without actually closing it behind you. Your breathing was slightly accelerated, your body tense as a violin string. What's happening to me? you asked yourself, biting your lower lip. You'd gone there to prepare for the next day's class, to escape the chaos of your personal life and to relax your mind, and instead you found yourself hearing every little noise like an amplified echo.
Then you felt it.
A breath that wasn't yours, behind your ear. You turned around, eyes wide, frightened, your heart pounding.
Mirio was right behind you. He hadn't left.
Standing less than a meter away from you, his eyes fixed on you with an indescribable hunger. But there was something in that smile, a hint of mischief, that made your stomach clench. "I'm just admiring the view," he said, touching your hair.
It was just the two of you, in the entire institute.
You felt your body react against your will. Then you quickly recovered. "No, stop… stop…" Your nipples hardened under your tight dress, the skin heated where your gaze lingered. Come on, I can't do this. I can't. It's wrong!
The strongest man in the school was there, right in front of you. The kind of man who turned everyone's heads, including the teachers, with his sculpted physique and that smile that lit up everything he saw. You remembered when Midnight told you about him one night, and she was deeply in love with him. That afternoon, however, with the sunset light painting his fiery features, he seemed almost… irresistible.
"You're beautiful, sensei. I have a weakness for… pregnant women." He leaned even closer, wrapping his strong arms around your growing belly, embracing you from behind. "I want to be… your lover."
His words hit you like a punch in the gut. What? Your brain screamed indignation, rejection, but your body… God, your traitorous body was already arching toward him, your breathing becoming shallow, your legs trembling slightly.
"Are you crazy, or what?" Your voice came out weaker than you intended, a whisper instead of a rebuke. He smiled, a mischievous smile. "Maybe. But not as crazy as you are, if you think about it." His fingers moved, brushing your arm, sending shivers down your spine. "I know you've been thinking about it since back in the library. I know you want it."
"I don't know what you're talking about." You lied. You both knew you were lying. You knew it from the way your pulse quickened under his touch, from the way his gaze kept falling to your lips, as if they were already waiting for a kiss.
"Really?" His hand slid further down your hip, until it rested on the tight skirt that hugged your thighs. You felt his fingers twitch slightly, as if he were fighting not to rip your clothes off, right there in the hallway.
You were already wet. Your panties stuck to your pussy, unbearable. "I know your body wants me." He caressed your beautiful ass over your clothes. "It's a shame Bakugo took you first...if only I'd known..."
He moved on to caressing your belly, with Katsuki's baby inside, alive. "You would have been mine, sensei. My own little doll. To be fucked hard every day, until I emptied myself inside you over and over again."
The images those words evoked made you blush violently. Heat rose from your cheeks to your ears. And he continued: "Maybe… I would have gotten you pregnant…"
You imagined it. Mirio on top of you, taking you gently, digging his fingers into your hips as he filled you with his cum, again and again, until you forgot the name of any other man. "You'd like that, huh sensei?"
He lifted your skirt slightly, caressing your legs over your light-colored pantyhose. The walls of your pussy tightened, your body responding with a burning desire.
"Mirio, please stop…"
"Do you want me to fuck you here? Now? While Bakugo is somewhere else thinking you're his?"
A moan escaped your lips as his hand slid into your soaked panties. "Mirio, no, that's enough…"
"Come on, sensei, just a little…look how wet you are."
"Stop it, Mirio, no!" you exclaimed, pulling away from him. He smiled, licking his fingers, full of your juices, and shook his head. His smile grew wider, more predatory. He brought his fingers to your lips, forcing you to lick your juices off his index finger. "Taste how wet you are for me," he commanded. "Taste how much you want me."
"Mirio, stop,"
"Do it, sensei. Do it and I'll stop, I promise."
You obeyed, your tongue wrapping around his finger, savoring the salty, sweet flavor of your desire, your cheeks burning with humiliation and arousal. Mirio moaned, a low, guttural sound, before grabbing your chin and forcing you to look at him. "Sensei, I won't stop here. Just know that."
Then he turned and headed toward the flight of stairs leading outside. You were incredulous, clapping a hand over your mouth, and looking around for a bathroom: you had to throw up.
