Teachers Pet (Eren x Levi Yaoi)

I had finished up some extra work as the period ended everyone was exiting to next period, I handed in my work walking towards the exit as I heard "where do you think your going Eren?" I heard him say from behind me "I'm going to next period Sir." I said, he grabbed me by the waist turning me to face him, I looked deep into his eyes, I was surely confused as to why This was happening, I heard him whisper into my ear "Eren..your not done yet..unless you want that A you will have to do as I say" he says picking me up sitting me down on his desk, I felt his hands move to my chest, shit. "Sir! This isn't allowed!" I yelled as I felt my cheeks turn red, he kissed me anyways not caring, his lips were soft yet rough filled with lust, I softly moaned as he started to unbutton my white dress shirt and messing with my hair, I wanted to push back but I couldn't, his kiss just..made me freeze as I felt him go down to my member, trying to unbuckle my belt "Sir..why?" I asked softly "because Eren..You want that A don't you?" He asked "yes Sir.." I responded "then you have to work for it.." He smirked as I felt pleasure over my body until I heard a knock on the door "It's principle Erwin, Levi I need to speak with you..Now.." Oh god...
