Notes Of course the first thing I ever publish on this site is smut. This is my first time writing smut and I'll probably delete it later. See the end of the work for more notes Midoriya Izuku sits at his desk and wonders what he has done in his twenty-five years of life to deserve being put in this position: a new teacher with his student’s lips wrapped around his cock. It could be a reward for weekly volunteering in community service projects, or punishment for almost knocking someone off the subway platform last month – he’s not sure. Bakugou Katsuki has been kneeling underneath Izuku’s desk for the last few minutes, slowly dragging his mouth over Izuku’s length and driving the teacher crazy. Katsuki had cornered Izuku during lunch break, kissing him breathless in the empty classroom until they heard a teacher calling “Midoriya-sensei” down the hall. Panicking, Izuku quickly pushed Katsuki underneath the desk and hoped whoever was interrupting them would leave before class started so Katsuki could leave and come back in with the rest of the class. Unfortunately, they were not that lucky. After his students were seated, Izuku told them to break into groups and work on their upcoming projects for next week. With a nervous glance, he walked to his desk and sat down, giving Katsuki enough space to breathe but hopefully blocking him from anyone’s view. Minutes passed by slowly and Izuku had begun to let himself relax, thinking they would be okay until the end of class. A hand brushing his crotch and slowly bringing the zipper of his pants down made him reconsider that. Izuku let out a small squeak and snapped his head down, hissing, “Kacchan, what are you doing?!” A smirk spread across Katsuki’s face, red eyes lit with amusement, and Izuku knew he was done for. Now, Katsuki’s tongue rolls over the head of Izuku’s cock and lightly flicks at the slit. Izuku can hear how shallow his breath is becoming and tries to calm himself. He takes a steadying inhale only to gasp as Katsuki suddenly dives down to the base and Izuku feels the head of his cock hit the back of Katsuki’s throat. Realizing he was probably too loud, Izuku coughs and covers his face as a few students look over with concerned eyes. He lifts his lips into a wobbly smile and the students turn away. A humming chuckle vibrates around his length and Izuku clenches his fists so hard they turn white. He looks down at Katsuki in what is probably meant to be a glare, but he fears he looks like a disgruntled cat in heat. Katsuki’s choking laugh confirms his suspicions. Burning hands wrap around Izuku’s legs to pull him closer and Katsuki dives in until his nose is buried in the course hair of his crotch. Izuku bites his bottom lip to keep his moan from escaping and instinctively grabs onto Katsuki’s hair. He’s not sure if it’s to push him away or it’s just because he needs to hold on to something. Katsuki slowly pulls off and the cold air hitting Izuku’s now-wet cock makes him shiver. Looking up, Katsuki says in a rough voice, “Oi, sensei. Put your hands back on the desk. Don’t want the students to think you’re doing something weird with your hand down your pants, do you?” Izuku felt himself slowly die inside. He lifts his shaky hand from Katsuki’s head and grabs onto the desk, hard. Izuku raises his head and scans his students’ faces to see if anyone’s caught on. He feels Katsuki’s tongue slide around his cock, teasing the thick vein on its underside. A shudder wracks through him and his knees almost lift and hit Katsuki in the head. Izuku hears an annoyed growl before feeling a small nip to the head of his cock and a high-pitched whine almost rises from his throat. The intense pressure in the bottom of his stomach almost explodes until a cold bucket of water hits him in the form of another student, Todoroki Shouto. “Sensei, are you okay?” Izuku freezes and hastily schools his features to resemble someone who isn’t getting a blow job from a minor during school hours. Thankfully, Katsuki has paused his ministrations, but has apparently decided to leave Izuku’s dick sitting in his mouth. The wet heat distracts Izuku and makes him squirm in his seat, but a pleasant smile graces his face and he replies, “Of course, Todoroki-kun. Do you need help with something?” “Are you sure? Your face is red and you seem as if you’re in pain.” Shouto raises an eyebrow in concern, intently looking at Izuku for any sign of distress. “Just feeling under the weather. How can I help-“ Izuku’s voice breaks before he can finish his sentence, brain stuttering as Katsuki creates a tight suction around his length and swallows. He feels his eyes bug out of his head and knows he shocked the student in front of him. Shouto’s mouth falls open and he almost seems like he is preparing to catch Izuku if he falls forward. Izuku rushes to calm Shouto and get rid of him before things get any worse. He lightly kicks Katsuki under the desk, hoping he’ll take the hint to stop. All he receives is a swat to the inside of his thighs. “I’m fine, don’t worry Todoroki-kun. What did you need?” Shouto doesn’t say anything for a second and just stares at Izuku. He takes a quick glance around the classroom and his eyes rest on Katsuki’s desk. Izuku’s heart pounds in his chest, praying he hasn’t figured it out. Looking back at his teacher, Shouto simply says, “Never mind, I think I know now. Thank you, sensei,” and goes back to his desk. Izuku quietly swears to himself, stress building up as he worries that Shouto has caught on. However, he isn’t given the chance to think about it for too long as Katsuki’s hand dips into the front of his pants and massages his balls. The sudden rubbing causes him to swear under his breath for a whole different reason. Izuku rests his mouth in his hand, trying to keep any noises from bubbling out. Tremors of pleasure rock through his whole body as he feels fingernails against his perineum, lightly scratching back and forth. Izuku presses his hands so hard to his mouth he distantly wonders if he’s leaving marks there. Pleasure sweeps over Izuku and he feels his balls tightening, the intense build-up that Shouto’s interruption had shut down quickly filling him again. Tears gather at the corner of his eyes from trying to hold in his moans. He is confused by the strange taste of metal on his tongue until he realizes he has bitten his lip so hard the skin broke. Katsuki’s finger presses up, right into his prostate, as he deepthroats Izuku’s length and Izuku shatters above him. His body sags in his chair as his cum shoots into Katsuki’s mouth. Quiet sobs shudder through Izuku’s lips and he opens his eyes, unsure of when he even closed them. Keeping his hand over his face, Izuku looks up at his students and relaxes when he sees that no one is looking at him. He looks at Shouto a beat longer just in case, but relaxes when he can’t find anything to suggest his student knows what happened. Izuku looks down at Katsuki and sees him staring back, tongue sticking out to lick away the cum spilling out of his mouth. His normally red eyes are blown black, pupils dilated, and Izuku can see Katsuki’s cock straining in his own uniform. A glance at the clock informs Izuku that the class is about over, meaning they're close to the quick ten-minute break between periods. His foot lightly traced the outline of Katsuki’s bulge, eyebrow raised in question. Katsuki’s smirk was all he needed for an answer.
