Chapter 9

"Sensei what was in that vile you gave me?" I wanted to feel more of him, I wanted all of him. He slid another tentacle around my arms and another around my legs separating them. I moaned at his touch before he kissed me roughly, he then whispered to me, " In that vile was a bunch of chemicals that made up a sort of potion. I had Okuda make it for me as one of her assessments, it includes all of the chemicals that can change a person's hormonal state," I was a little freaked out that my hormones were being tampered with but at this moment, the need was taking over. I cried out, "Koro-Sensei! Please, I need you to take me," He laughed and told me to hold still, suddenly, it felt like he was straddling me and i could feel nothing but skin on skin, which meant he was completely naked right now, god i wish i wasn't blindfolded. I then felt something at my entrance but it wasn't a tentacle. Suddenly, without warning, it slammed into me before letting me adjust to the sheer size of it. That's when I realised that it must be Koro-sensei's member. The mental image and intense pleasure made me shudder; this was what I was waiting for, what I was yearning for what seemed like forever. I moaned loudly as Koro-sensei started moving, he too was breathing heavily, his member was incredibly deep inside me and he then hit that spot again. I groaned at the pleasure and I heard him laugh again. I was near an orgasm and I could feel he was too. Suddenly, I felt the handcuffs being released and I was flipped over so I was on my hands and knees. Oh god this was too much for me to bear. We finally both came but Koro-sensei obviously wasn't finished just yet. He laughed as we both panted and said, " y/n? Can I do something else to you?" I nodded and became curious, this damn blindfold! He laughed again and said, "Ok, open your mouth wide," now I knew exactly what was coming, I obeyed him and I felt his member on my lips. I decided to surprise him so straight away I deep throated him, he groaned at the pleasure and wrapped his tentacles around my arms; I too moaned and brought in a little tongue action earning another moan from him. He started throat fucking me, I tried not to gag, I could tell he was about to cum when i felt is member twitch and his thrusts become sloppy, "y-y-y/n, I-I-I'm about to..." He came in my mouth and I swallowed every last drop. It tasted a mix of sweet and salty, interesting. Before I knew it, the blindfold was no longer on and both he and I were clothed. His face was bright pink which made me chuckle, "Koro-sensei thanks for such a good lesson, you really are an amazing teacher," He smirked at my comment, "No, I think it is you that I should be thanking, you are an extraordinary student," I pulled him into a hug and kisses him softly before pulling away, "No worries sensei, now I really must go, my mum will be wondering where I am. I can't remember if I told her about our 'extra lessons'," he nodded and waved at me as I exited the PE shed. What a lesson. If only it wasn't for the blindfold. I walked home smiling like an idiot and didn't stop smiling until I got in the house.
I walked in to see mum in the living room watching an American TV show called Ink Master, something about tattooing. I sat next to her and watched the rest of the episode with her before turning to her and saying, "Sorry I'm so late home, I can't remember if I told you that I was having extra lessons with my teacher and we got stuck on a maths problem, something about linear sequences inside of quadratic sequences," she looked at me and laughed, "You know y/n, today has been a really strange day. First of all I dream that I have a large yellow octopus next to me in the bedroom and when I went to check everything for my policeman cosplay I'm doing this year, my handcuffs were gone! Now you come home late and tell me that you are actually getting your grades up, wow!" I blushed at the middle part of what she said, damn you Koro-sensei, you took the handcuffs from my mother's draws! I laughed and said, "I'm sorry about the handcuffs, I-uhh, I moved them, I needed to-uhh borrow them for a school project, yeah..." I was hoping that she was too tired to notice the nervousness in my voice and thankfully, she went along with the lie, "Oh don't worry about it darling, could you just put them back once you've finished with them?" I nodded and went upstairs, when I opened my bag, sure enough, there were the handcuffs. Oh Koro-sensei... I went and put them back in my mum's cosplay wardrobe before going back into my room and started doing the homework that Karasuma and Bitch-Sensei gave us. All the while dreaming of Koro-sensei...
