Context: you had one of those student on teacher crushes on Aizawa because how could you not, but you didn't know he knew.
You were sitting in Aizawa's class, your last period of the day. Every time he walked by you, he would lightly graze your shoulder with only the tips of his fingers. Right before the bell rang, you heard your name from Aizawa "Mx. (Reader)," he spoke up, "Please stay after class."
Of course, being the dirty minded little brat you are, your mind immediately started to wander into the "he wants to fuck me-" category. Not that you're wrong, but still.
After everyone else left, Aizawa locked the door, sealing the two of you in. Which obviously made you scream mentally.
After he locked the door, he turned to see your adorable little blushy face. He chuckled walking over to you. You were still sitting down, so he towered above you. When you looked away, he grabbed your chin, turning your head back to face him. He lifted your head so you didn't have a choice but to look up, directly into his eyes.
He smirked at how red your face was, his hand slowly traveling down to wrap around your throat. He chuckled as your breath caught in your throat, making your face even redder.
"You think I haven't noticed how you act up around me? You're such a fucking brat. I can feel your heart racing, baby.. and knowing it's all for me, makes me want to break you so bad that the only word left you can remember is my name."
Aizawa used his free hand to slip under your skirt and gently caress your thigh with the tips of his fingers, like he had been doing to your shoulder all class.
Encouraged by your soft whimpers, he gradually traveled lower, eventually crawling under the desk. He ran his tongue along your inner thigh, loving the noises you were making because of him alone.
He kept teasing you for a few minutes, until you were begging him to just eat you out already. He chuckled before gently blowing gently on your sensitive entrance, to tease you a bit further. He leaned forward and slowly circled your clit with the tip of his tongue, holding you down by your hips so you couldn't do anything but take it.
He kept up the teasing, until you both heard the door unlock. He hummed before wrapping his lips around your clit and gently sucking, to see how well you could handle yourself while talking to somebody.
Present Mic walked into the room, scanning it with his eyes before he finally landed on you. He walked up to you and asked if you'd seen Aizawa anywhere, and you shook your head, just trying to keep your cool.
You had a full conversation with Present Mic while Aizawa was going wild on you right below. After Present Mic bid you farewell and told you to tell him if you see Aizawa, he left the room and closed the door behind him.
After Present Mic left and closed the door, you grabbed Aizawa by the wrists and lifted him up, pinning his wrists to the table. You lifted the both of you up onto the desk, straddling his waist and teasingly grinding against his erection through his pants.
Aizawa groaned at the teasing, his hips jerking upwards. "I want you.." he uttered under his breath, looking up at you with pleading eyes. But you weren't gonna let him have it that easily after all the teasing.
You kept his arms above his head with one hand, grabbing his face with the other so he couldn't look away from you. You smirked down at him, slowly speeding up your pace a bit, making him groan again. "Beg for it." You whispered, making chills run down Aizawa's spine.
He didn't want to beg, he was usually the dominant one in relationships like this, but he couldn't help but feel compelled to. So despite his initial hesitation, he softly pleaded with you to fuck him. "P-please.. I need you, I need you so bad. I want to feel the tightness and warmth of you around me.. please.."
With a pleased smirk, you tugged his belt off, then his pants down. You gave him a few gentle strokes, before lining his throbbing member up with your dripping entrance.
As you slowly lowered yourself onto him, the both of you let out low moans, Aizawa's hips bucking up into you. It was almost pitiful how desperately he wanted and needed you.
His low groans turned into high pitched whines and whimpers as you started riding him, his hips jerking upwards occasionally.
"I'm so close, please don't stop.." he managed to whimper out, which made you chuckle and speed up your pace a bit.
Aizawa's back arched as he came undone, spilling his thick semen into your waiting womb. You gasped as you felt the warm liquid pooling inside you, collapsing onto Aizawa after he was finished.
He was breathing heavily, his eyes closed as he gently stroked your hair, a soft, warm smile forming on his face as the two of you basked in the passionate afterglow.
