This is my first time writing on fanfic

It was 11:00 at night and Levi was doing paperwork-because he couldn't get to sleep Levi decided to do some paperwork. Even though Levi felt tired he still carried on with the work. A lot of the people were asleep, he had a major struggle to get Hanji into bed-the new recruits having a pillow fight and Levi had to punish a few for being naughty, even Erwin went to bed early for no reason. Levi started another page-he continued with Eren's report for Sir Darius Zachery, after a couple of minutes Levi had finish Eren's report. Out of the blue Levi gave out a yawn and a long sigh. "Might as well", Levi said to himself, he put his arms on the table rest his head and fell asleep. "l-l-Levi… ha". "Your inside...is amazing". "I'm…c-cumming-. Levi woke up in a shock, why the fuck humiliates strongest still dreaming about sexual fantasies at his age-Levi looked at the time on the wall he could see in the moonlight, the clock said 12:36. Levi decided it would be best to get up and go to bed, Levi got up-light a candle and walk to his bedroom. As he arrived he noticed Eren had fell out of bed-Levi picked Eren up and placed him back in bed, Levi went to his chest of drawers and got a fresh pair of underwear out-he walked back to his side of the bed stripped his top half off. Then Levi removed his trousers and chucked them on top of his top, he was about to remove his underwear when he saw a small bulge. "God damnit", Levi muttered. He pulled down his boxers and sat down on the bed- he got some lube and he squirt it on his left hand. He leant over to smell Eren and that instance his length was rock hard-Levi rubbed his hands together and his right hand touched his aching cock. Levi pumped his length while his free hand went down to rub his balls, this felt awesome for Levi-amazing and sweet. Levi then slipped back into one of those odd fantasies-he thought of the brat sleeping next to him. "Ha…Eren that's…. amazing", Levi moaned, his moans filled the room. "Yes go Erin", Levi moaned louder. Levi's left hand travelled up his stomach towards his chest and twisted a nipple-Levi gave out a high pitch whine, then the hand went back down to his ass and popped two fingers into his hole. Levi moaned even louder as he pressed his fingers against his prostate, his right hand rubbed his length fast while his fingers pushed against his prostate. Levi was getting close-Levi gave a few more hard thrusts then he moaned really loud. "AHHHHHH….EREN", Levi screamed out Eren's name-Levi's seed shot out from the tip and landed on the bed and floor. Levi fell back onto the bed-trying to recover that intense orgasm-that was the most intense spasm Levi had ever had. Levi sighed and pumped the rest of his cum out of himself. "So you were thinking about me", Eren asked out of the blue, Levi went red in the face. "Y-you were listening", Levi stuttered. "Well yes cause your moans woke me up, can we go to sleep now", Eren asked. Levi replied-he cleaned the floor, cleaned his private area-put the fresh underwear on and climbed into bed. Levi blowed out the light and cuddled in with Eren.
