In Love With Sensei ~ (KoroSensei X Reader)

-LEMON AND SMUT AS WELL AS FLUFF YOU'VE BEEN WARNED-

You look at KoroSensei as he's teaching class. He looks at you just as you did. You pretend you weren't looking at him, and he seems a little hurt, flinching visibly. Another student notices and tried to shoot him with the anti-him B-b's. He moves quickly and catches the B-b with chalk. He sends the student to the back of the room. You smirk and pay attention to KoroSensei again. He's writing on the board with the chalk, probably doodling as the class does their class work. You were finished, your pencil still in hand as you also loved to doodle when you were bored. You knew KoroSensei couldn't draw very well, but somehow he always loved to raw anyway. You were the opposite mostly, you were pretty good, and drew mostly what was on your mind. Usually this was KoroSensei. But today, you were feeling exceptionally moody~, and began to draw KoroSensei, eating IceCream. Every detail was thought out, and you were about to finish when the paper was suddenly snatched from your desk. You looked up to see KoroSensei staring intently down at you. You were a girl, which also meant that he was pretty attracted to you. He looked at the picture, and blushed, something about the picture was driving him crazy, you could tell. He blushed and looked at you with a slightly pink face.
"(Y/N)-chan, why am I licking the IceCream? I takes bites, you know that don't you?" He teases, wagging his finger at you. The class smirks and whisper to each other. You blush.
"Actually Sensei~, I just felt like drawing you licking something, you're cute when you stick your tongue out~." KoroSensei flinched and made his signature poker face, sweat dripped down his face. Wow, that was a strong reaction. This will be a fun year~.
