Kenma looks at you with that look, the kind of look that no one would be able to mistake as anything other than flirting. Looking up at you with half lidded eyes, slightly biting his lip while tracing the indent of his desk.
You'd be lying if you said that look wasn't tempting. God knows how badly you want to ruin this boy, destroy his confident and flirty demeanor and make him cry. You don't even know where he got it from, he usually keeps to himself. You wonder if he learned it from somewhere or if he just recently showed his true colors.

It gets hard to hold back when Kenma purposely tries to get detention.
He flings a pen at the back of your head and smiles.
"Kozume." You cross your arms. "What's your problem?"
He shrugs. "Sorry sir."
You sigh and brush it off, turning back around to erase the board. He flings two more pens at you.
"See me after class." You say sternly, picking the pens up and placing them at his desk. "I don't think you want to know what'll happen if you keep this up." You lower your voice so only Kenma can hear.
He holds back a moan and rubs his thighs together, staring at you with clear and undeniable lust but you manage to ignore it.
Kenma waits at his desk until the last student leaves and immediately goes up to yours.
"I'm considering transferring you out of my class."
Kenma's eyes widen. "No- why?!"
"You know why, Kozume. I don't think you're learning properly in my class either, you don't pay attention."
"I'll be good sir, please! I'll stop I promise." He frowns. "I'll be a good boy for you.."
You sigh heavily, trying to ignore how attractive that sounds. "I don't know. I really don't think you should be in my class anymore."
"Are you worried you're going to make a move on me?" He looks at you shyly. "I'll let you do whatever you want to me, so don't worry.."
"I have every right to call your parents and arrange a meeting with the principal, I am not going to do anything with you."
Kenma climbs onto your lap and wraps his arms around your neck, his lips dangerously close to your ear. "Don't you want to have your way with me, sir?" He grinds down onto your crotch.
Your breathing becomes ragged as he speeds up and whispers more dirty things into your ear. "I know you've fantasized about it, I know you wanna be inside me."
You grab his hips. "Fine. You win." You pull his cardigan over his head and rip his collared shirt open, buttons flying everywhere.
Kenma gasps and quickly unbuckles his belt, you help him tug his pants and underwear off. His wet cunt dampens your pants.
He unbuckles your belt next with much more vigor, messily unzipping your fly and pulling your pants down. He basically drools at the sight of your hard length in your boxers.
Kenma tugs it off and moans. Your hands find their place on his hips and lift him up, slowly pushing your tip inside him before slamming him down.
Kenma covers his mouth in shock, almost having an orgasm.
"Start moving."
Kenma barely processes what you said, completely consumed by euphoria.
You slap him. "I said start moving, bitch."
He whimpers and starts riding you, gripping your shoulders for balance. You stick your fingers into his mouth and he gladly sucks on them.
"Say thank you."
"Thank you sh- sir~"
"For what?"
"Fo- for fuh- fuckinggh~ me~"
"I'm not fucking you, baby."
"Hhng~ thank yo- you for let uh~ letting me fuc- fuck myself on- on your c- thi- thick cock~"
"That's right, making a mess of yourself on my cock and only caring about your pleasure."
Kenma notices your unamused expression and stops.
You pull your fingers out of his mouth and slap him, the wetness making it hurt more. "I didn't say stop."
Kenma goes back to bouncing, on the verge of tears. "Sorry- 'M sorry~!"
"You're such an ugly crier, makes me want to hurt you more." You slap him again.
"Ah-" Kenma squeaks. "Hu- hurts~"
"Not what you expected, slut?" You pick him up and lay him down on the desk, finally showing him how it feels to be fucked. "And what do you say now?"
"Th~ thank you~ fo- for fucking me~ sir~!" He sobs happily.
You spit on his chest, slapping it and making him mewl. "Such a loud little bitch, want your other teachers to see you whoring yourself out for me?"
Kenma tries to cover his mouth but you hold his hands apart.
"St- stop~! Ple- please!" He sobs loudly, unable to hold back his moans. He doesn't want you to stop but he can't get caught.
"How will your parents react? Finding out you seduced your teacher instead of focusing on your studies."
"Sir- sir~!"
"What'll they think when you end up pregnant too?"
Kenma's eyes widen. "Please no! I'm beh- begging you~!"
"But you came to me, acting like a slut, saying you'd let me do whatever I wanted but now you're upset? Now you don't want it?"
"In- in my mou- mouth ple- please~!"
You roll your eyes and pull out. "Get on your knees, right now."
Kenma scrambles to get on the ground, head fuzzy and body weak. He kneels in front of you and opens his mouth, hoping you'll just shove it in his mouth or jerk yourself off.
You grab the back of his hair and force his mouth to swallow your cock, tugging him back and forth as you reach your completion.
He looks up at you with tears in his eyes. You can't tell if he's enjoying himself or if he absolutely hates it.
You shrug off the thought and release into his throat, he quickly swallows it. And again, you can't tell if it's because he wants to swallow it or because he thinks he'll get punished for not doing it.
"And what do you say?"
"Thank you for coming inside my mouth, sir." He looks up at you sweetly.
You pick him up by his hair and drag him to the open window, slamming his bare body against the cold glass.
Kenma looks down in horror, anyone could see him right now. That is if they had a camera that could zoom very well, since it's the third floor, which hopefully is unlikely.
"I'm not done here so you better shut the fuck up and take it like a good little whore."
Kenma moans. "Yes, sir."
You scoff, of course he's enjoying this. "Fucking slut." You enter him again, slower than before.
He giggles. "I'm such a fucking slut, sir~"
"You were pretending earlier, weren't you?"
He smirks. "Sort of. It turns you on though, right?"
Your hand creeps up onto his throat and grips it lightly. "If we're going to play that kind of game, just know that I won't stop until I'm satisfied. Even when you're crying and genuinely begging for me to stop, I won't."
Kenma moans and shivers. "Yes sir~"
"And don't worry, I won't come inside." You lie.
Kenma sighs in relief. "Thank you sir.."
Without warning, you tighten your grip on his neck and start thrusting. Kenma quickly turns into a moaning mess.
"Oh god~! So- ugh~ good~!" He rolls his eyes back.
"Can I tell you something, Kozume?" Your breath is cool against his ear.
"Yesh~"
"I love fucking 3rd years, you all are so fucking tight and inexperienced. So fucking easy to ruin before they can even graduate and meet a nice guy." You groan in his ear. "On the cusp of adulthood but still retaining their innocence, so easy to mold."
Kenma whines, hating that he's not the first student you've had sex with.
"So submissive and easy to manipulate too, I could ask you to drop out and marry me and you would, wouldn't you?"
Kenma nods the best he can with your hand wrapped around his throat. "Wan- wanna be your wif- wife~"
"Aw, you wanna be my wife?" You say mockingly. "Y'know, it might actually suit you better since you're such a fucking cock slut."
"Ph- please~ sir~"
"Whore."
Kenma mewls in surprise at the chilling tone in your voice. His back arches against your chest as he comes.
"Look at yourself, you're having an orgasm because I called you a whore! And you think you should be my wife." You laugh.
Kenma sobs. "I'm sor- sorry-"
You pull out and turn him around before resuming your rhythm. "You're only good for being a living sex toy, don't get ahead of yourself."
"'M sorry sir~" He almost chokes on his tears. "'M just a se- sex toy~"
"That's right, just a stupid doll." You speed up your thrusts. "And this stupid doll is gonna let me come inside it, right?"
Kenma shakes his head rapidly. "No! No! Please! You pr- promised!"
You ignore his desperate begging and keep fucking him, adjusting his position so that you reach him deeper.
"Sto- stop! Pl- pleas-" His eyes widen when he feels your cum enter him. "No- I-"
"Say thank you."
Kenma shakes his head. "Please pull out!"
"Say it, bitch." You slap him.
"Than- thank you! For co- comin- coming insi- inside me sir!" He says in between sniffles and sobs.
"Good boy." You pull out of him and let him drop to the floor. You watch as he weakly tumbles to your desk to get tissues.
"Don't want this anymore?" You ask.
"Want it...I want it.." Kenma sniffles as he tries to clean out the cum. "But I can't- I don't want to be pregnant-"
"You're so cute, you're making me want to come inside you even more."
Kenma looks up at you in fear. "Please...please don't!"
