Summary: Your usual daily workout gets interrupted by your elusive Sensei
A/N: This is my first attempt at writing for jujutsu kaisen so please be kind and expect a smutty second chapter to this soon!
"Why do you always work out after class, you're already top of our year." Yuji asked as he walked alongside you, arm loosely hung around your shoulder.
You shrugged lightly, gripping your gym bag in your hand, "I'm not like you guys, I have no special powers. I can see curses but aside from that, I'm normal. I need to keep sharp to stay alive, you know that." It was true. Nothing about you set you apart from the average pedestrian. You'd been thrown into this life after a grade three curse had attacked at a school football game. It'd done minor damage and a certain boy with spikey black hair and demon dogs had shown up to deal with it. The only thing that made you different was that you could see the slug-like creature crawling up and down the field looking for someone to latch onto.
After that, you saw curses everywhere you went. Crawling up buildings, attached to people, it'd turned your life upsidedown. Eventually, you'd sought out Megumi, looking for answers and help. Now you were climbing up the ranks quickly based on quick thinking and strategy. It'd caught the eyes of many of your superiors as well as Yuji, your newly proclaimed best friend.
"That's not true" He groaned, stopping you in front of your destination, "You're so much more than all of us, everyone sees it. You're probably the strongest one here, you just don't know it yet, (y/n)."
A blush dusted your cheeks "Thanks Itadori, but not all of us can punch holes through walls like you." He smiled lightly at you, reaching down to ruffle your hair with a grin. "I'll see you later, kid." He grinned before turning to walk away down the hallway and towards his dorm.
"I'm older than you!" You yelled towards his retreating figure, you watched as he turned, walking backward "Yet you still love me."
Finally, you turned towards the gym door, opening it to begin your daily workout. Almost every day the gym was empty, free for you to do whatever you wished. Lately, you'd been working on kickboxing and defensive maneuvers. You had to stay sharp, one slip up could cost you your life at the hands of a nasty curse. The thought only made your resolve stronger as you entered the room. Although you suddenly found yourself distracted at the sight of your Sensei.
Shirtless.
To be honest, you'd spent little time outside of class together, Gojo got along well with his other students but seemingly avoided you. He often didn't take you out for missions like he did Yuji or Megumi and didn't greet you in the hallways in passing. Yet you couldn't help but let your eyes linger on his body as he kicked and hit the punching bag.
His white hair swayed with every movement, his back turned to you, muscles tensing with every throw. You felt almost entranced as you watched his shoulder blades move and listened to the small grunts leave his mouth as he slowly exhausted himself.
All the times you'd seen Gojo 'fight' he was using his powers. Always so teasing and calm even in the face of special grade curses. But what you were witnessing was so different. Gojo seemed frustrated as he threw punch after punch, sweat beginning to drip off his hair in little droplets. God knows how long he'd been in here.
For a moment Gojo stilled, wiping his face with his hands as he straightened out his back. "Enjoying the show?"
You looked down at the floor in shame, bending down to remove your shoes to step on the mats, hiding your red cheeks from your superior. "I'm sorry Sensei, I've just never seen you in here before."
You could hear him scoff from the other side of the room. By the time you'd unlaced your shoes and looked up again he was facing you. His blindfold was off and you felt your breath catch your throat, his piercing blue eyes looking at you in amusement. "I know you come here a lot, I can leave if you'd like the space to yourself."
You stood up, bowing slightly toward him as you stepped onto the mat. "That's not necessary sensei."
Gojo let out a chuckle, turning back to the punching bag and letting his knuckles brush across the red canvas material. "We're not in class right now, no need to be so formal (y/n). Call me Gojo."
You hesitated for a moment. Something about calling your teacher by his name felt off but regardless you let it roll off your tongue. "Okay...Gojo."
With that a comfortable silence blanketed you two, both individually continuing your workouts. The only sounds leaving Gojo's lips as his hits continued to echo against the punching bag. His presence was a calming one and you found it increasingly harder to not turn to look at him. But you had a task at hand, you needed to stay on top, and with that, you entered the basic fighting stance and started swinging at your own punching bag.
Thirty minutes had gone by and you could feel your sensei's eyes on you, Gojo's eyes. You tried to pay it no mind until he walked up behind you, "You're doing it wrong."
You stilled for a minute before going to turn, "What-" He cut you off by putting his hands on your hips. He bit his lip as he looked down, his brows furrowing in concentration.
"If you stand like this." He paused, adjusting your feet with his own, "You'll be able to pull your arm back without leaving the rest of your body so exposed as well as getting a stronger punch."
You could feel his breath on your neck as he moved you, and the warmth of his hands on your hips was dizzying. You longed to feel more of it. Your cheeks heating up at the obscene idea growing in your head.
What if that warmth was all over your body.
You were snapped out of your thoughts when he removed his hands, stepping back with a small smile. "Try hitting it now."
With a nod you stepped forward, twisting your body and extending your arm, letting out a grunt similar to Gojo's before as your fist made contact with its target. The punching bag moved slightly, more so than before. A smile erupting on your face as you turned towards him. "Thank you Sensei-" You stuttered momentarily at the look on his face, "Gojo. Thank you Gojo."
He smiled at you before reaching into his grey sweatpants for his blindfold and wrapping it back around his face. You almost felt like some of the light had left the room as he covered his eyes. "We should do this again sometime." Gojo said as he reached down to grab his own gym bag, "Maybe next time you can practice on me." He grinned.
You lowered your head again, your smile getting bigger as your blush spread. Nodding shyly at the ground you heard him walk out the door. Hopefully, you'd get a chance to take him up on that offer.
