Teacher!Dr Veritas Ratio x Student/Female!Reader(Honkai Star Rail)

Y/N's POV

" Fail!" He said as he slammed the paper down in front of me. " W-What? How?" I asked. " Tch. Like I should know. I may be smart but I'm not all-knowing." He said as he walked away. I looked at my test and saw the score. " How did I fail? I studied so hard." I asked myself. I've been a student in Dr.Ratio's class for about a year now and I believe I'm his worst student.....ever. No matter how hard I study I always fail. For this most recent test I studied for over 100 hours the entire week. I don't know what's wrong but my grade keeps slipping. My parents say that if they keep slipping they won't let me see my friends, have a social life, have my communicator, or go out until they improve.

If they see this test I'm done for. I knew I needed to get my grade up. Once class was finished and everyone left the room I went up to Dr.Ratio. " Um.....Dr.Ratio?" I asked. " Yes, what is it? I don't have time for idiots." He said. I felt a little hurt but shook it off. " I wanted to ask about my grade." I said. " Oh you mean the worst grade in the class? The grade that wanted to make me pull out my eyes at how bad it was? The abomination of my student failing to understand my perfect method of teaching? That grade?" He said. " Y-Yeah that one." I said. " What about it? Are you looking for a way to get rid of your stupidity?" He asked. 

" Um....yes. I was wondering if there was any way i could improve my grade." I said. He started laughing. " The only way to improve that pitiful grade is to improve that tiny brain of yours. Study, review notes, just get better. There is no extra credit in my class." He said. He turned his back to me. " P-Please. there must be something. I-I'll do anything." I said. " Anything you say?" He asked. " Anything." I said. " Well too bad." He said. I lower my head and began to walk out. 
" However...." He said. I turned back to him. He turned to me and leaned against his desk. " I'm willing to be persuaded into changing your grade." He said.

" You are?" I asked. He nodded. " I'm willing to raise your grade if you do something to me." He said. " What do you want me to do? I'll do anything." I said. He smirked a bit. " I'm willing to raise your grade if you are willing to cross the line with me." He said. " Cross the line? What do you mean?" I asked. " Something forbidden. Something that shouldn't be done between a teacher and his student." He said. " Something forbidden?" I asked. " Yes. I want you to give yourself to me tonight and let me have my way with you." He said, crossing his arms. My eyes widened.
" W-What?!" I asked. " You heard me. I want you to give yourself to me tonight and if you please me, I will raise your grade and make sure you have full marks in the class always." He said. 

" No. Absolutely not. I can't. I-I won't." I said. " Then I guess you want to be an idiotic failure for the rest of your life. letting down the people who care about you. Seeing your parents sadden with the burden of taking care of an idiot like yourself." He said. I didn't want to be seen as a failure but was this my only option? I thought about it for a few moments and realized I had no choice. " Alright. I'll do it." I said. " Splendid. Meet me tonight in my office." He said. 

Time Skip....

I lied to my parents and told them I was going to the library to study and to not wait up for me. That wouldn't make them worry. I made my way to Dr.Ratio's office. Once outside of it, I knocked on the door. " Come in." I heard him say from the other side. I took a breath before opening the door. I saw him sitting at the desk correcting some papers. " Ah, you're finally here." He got up and walked over to me. " Are you ready to give yourself to me?" He asked. I nodded. He smirked and grabbed my hand. He led me out of the office and to his room upstairs. he opened the door and led me inside. " I had to ask you to come to the office. If people saw you coming up here, they'd be suspicious." He said. 

He shut the door and locked it. " Now we can begin." He said. He walked over to the bed and sat down on it. " Strip." He said. I tense up but did so. I removed all of my clothes until I was naked in front of him. " Now kneel in front of me." He said. I go up to him and kneel in between his legs. He spreads his legs apart even more and pulled down his pants and boxers. " Now.....use that pretty little mouth of yours and suck." He said with a smirk as he leaned back on the bed. I leaned closer to his cock and started licking the tip. " I said suck, not lick." He said sternly. I quickly took his shaft into my mouth and started sucking on it. " That's it. Take it deeper." He said. I start deep throating it. 

" Good girl." He said. I swirled my tongue around his shaft and began bobbing my head. " Just like that~" He said. He gripped my hair tighter and started moving my head on his shaft. I started gagging on his cock. " That's it. Take my cock." He said. It was hitting the back of my throat. I moaned a bit causing vibrations to be sent through his cock. " Shit." He said. He gripped my hair tightly and pushed my mouth onto his cock so that there were no gaps. He then let out a small grunt and came. I pulled away and wanted to spit it out but he covered my mouth. " You better not waste a single drop." He said. I then swallowed it. It tasted very bitter.

" Good girl." He said. He the pulled me up and tossed me onto the bed. He then took off his remaining clothes and climbed over me. " Spread your legs. I'm going to taste you now." He said. I then spread my legs a bit. He trails one of his hands down my stomach and in between my legs. He then starts to rub my folds. " Nngh~" I moan. " You like that, don't you? You like when i touch you here." He said in a raspy voice. " Nngh....Ratio~" I moaned. He roughly thrusted his fingers inside of me. " I never aid you could moan my name." He said as he thrusted his fingers deeply into me. " Aahn...nngh....s-sorry ah~" I moaned as I gripped the sheets. He curled his fingers inside of me, hitting my g-spot. " Aahn~" I moaned. " Oh, so that's your sweet spot." He said. He aimed each thrust at that spot. 

My head was spinning. I was experiencing so much pleasure that I started seeing stars. I felt my walls contracting around his finger. " I-I'm going to cum." I said. " Good. Cum for me Y/N." He whispered into my ear. That sent me over the edge. I let out a loud moan and came around his fingers. He pulled his fingers out of me and licked them clean. " You taste so good." He said. he then licked up my juices using his tongue His tongue felt so good on my folds. He pushed me closer to his face and kept licking. His tongue darted in and out of my wet folds. " Nngh....aahn~" I moaned. I could feel another orgasm coming just as quickly as the last one. 

He licked faster, sending waves of pleasure through my body. He moaned against my skin, sending vibrations as well. "Nngh....I'm gonna cum again." I said. I let out another moan and came again. My juices splattered onto his face. He wiped his face and licked it all up. "Hmm... If I were a food critic, I'd say this was a passing meal." He said. I blushed. he chuckled and lined himself up with me. " I'd ask if you are ready, but I expect you to be prepared for anything." He said. he then inserted his entire length into me. I let out a loud moan and wrapped myself around him. He wasted no time and started moving.

" Aahn...nngh....haaa~" I moaned. " That's it. Keep moaning for me." He said. He went deeper and deeper with each thrust. " Sensei....Ratio~" I moaned. He smirked when I called him that. 
My back arched because of the pleasure I was feeling. My head was in such a daze. He was making me feel so good. " You're clenching around me perfectly. Nngh...I can't get enough of you." He said. " Aaahn....haaa~" I moan louder. I had a feeling that some people definitely heard us. After a few more minutes I could feel his cock twitching. " I-I'm going to cum." He said.
" P-Pull out then." I said. 

" Hmm....I don't think I will." He said. " W-What?!" I said. " Just because you're an idiot doesn't mean I don't want to pull out. If you want to redeem yourself and not be a failure then you have to be challenged. And I think that giving you a baby will be the best challenge." He said. He then gripped my hands tightly and let out a low groan. I felt his seed filling up my womb. This pushed me over the edge too and I came. He then pulled out of me and looked over my body.
 " Absolutely perfect." He said. I then passed out and fell into a pleasure induced sleep. 

Time Skip....

" A perfect score again. Well done Y/N." Dr.Ratio said as he handed back my test. It was a low 70% at best but because of our arrangement, he gave me 100%. It has been a couple of weeks since I had slept with Dr.Ratio and i have gone back to him a few more times. He's also been helping me study so I'm not really getting a free pass and will earn a perfect score one day. 
" Oh Y/N, stay after class for a bit. There's something I need to talk to you about." He said. " Sure Sensei." I said. Once the bell rang and everyone else left, I was alone with him. " Come here." He said as he sat in his chair behind the desk. I get up and walk over to him.

He lifted my shirt up a bit. " You thought you could hide it, didn't you?" he said as he rubbed my stomach. " I just found out this morning." I said. " Likely story." He said. He leaned closer to me. " You know I have to punish you for keeping this little secret." He said. I blushed. " Don't worry. I'll still give you the most pleasurable sex every tonight but I promise not to harm the baby." He said.
