The First Time My Piano Teacher Used Me

So I wanted to be a famous pianist for a long time. I've gone to different classes and at the age of 13 my mom got me individual lessons from a pianist who was famous in the area. The classes were great and I really learned a lot from him. Lets call him Pete. I was going to pete's classes for about two months (1x every week for 2 hrs). Pete always told me that there is more to become a pianist just playing good wouldn't work. He always sat besides me while playing and he sat really close. At that time I didn't get it but his hands were too close. Sometimes he would rest his hand on thigh. I never said anything because he was my teacher after all. On a few occasions his hand would slip down my thigh and even rest between my legs while I was playing. One day he told me that being close to the teacher is important to get better and of course I believed him. He then told me to sit on his lap while I play. I thought it was kinda weird but I did as I was told. I was wearing thin sports shorts that day because it was quite hot and summer. He was wearing some kind of thin black linen pants at that time. I sat on him while playing and I felt a bulge on my bum. I did that for about 5 minutes when he put his hands on my hips. He told me to keep playing and he would help me to "feel the music". So I turned the page over and continued. He then made me move back forth and in circles in the rythm of the song I was playing. His cock was rockhard and obviously pushing against my bum while he was doing that. He did that for a long time. Near the end with his hands on my hips he used both of his thumbs to kinda spread my bumcheeks apart. He then pushed me down and I could feel his long hard bulge between my cheeks. Pete then put both hands on the side of my bum pressing both cheeks around his bulge. He rubbed and rocked me back and forth some more and after some time he stopped and let out a long breather through his nose and let go. Pete then put both his hands on my thigh and he continued to teach me like that for the rest of the class. After some time I felt his bulge disappearing. I did not realize that Pete had used my bum to rub his dick and make himself shoot loads of cum inside his underpants. Pete made me feel the music for the next 5 weeks everytime during our private class. I can confidentely say now that he made himself cum each time. The following week I was in his class again. We were about 30 minutes in. Of course I sat on his lap and he was grinding my ass on his rock hard cock. After I finished the song he made me stop before continuing. He told me that he could inaugurate me into the secret of becoming a famous pianist. Of course I was eager to learn the secret. Pete told me that this is a secret nobody can know about and that I had to swear to never tell anybody. I answered that I was willing to do anything to achive my dream. I agreed to keep this our teacher student secret. Pete was saying that its important to become one with the teacher. I didn't understand and Pete told me that I was going to learn today. I was sitting on his lap the whole time and he told me to stand up and rest my arms on the top of the piano. He said that I should tell him if anything hurts and I noded. He told me to spread my legs apart a bit and to relax and be quiet. I did as I was told and I felt pete pulling down my soccerpants and undies. Shortly after that his tongue touched my anus. It felt funny but not bad. I told him that my bumhole was dirty he responded in saying that it was as clean as it could get. So I stood there for about 5 minutes. Pete spread my cheeks apart and was licking and tongueging my asshole. I got used to it and to be honest it felt quite good. He then told me to relax some more and he begun to shove his little finger slowly inside of me. He has licked his finger before so it didn't hurt but I felt some pressure. He left his finger inside of me for some time and with his other hand he reached forward. I did not realize it myself but my little hairless dick had gotten hard aswell. He put the tip of my dick between his index finger and thumb rubbing a bit forward and back again. It was the first time getting touched down there by someone else but it felt good. He told me that I was doing great and he could feel that I was the right student for the secret. I told him that it felt good and that I was happy. He then pulled his hand back away from my dick his finger slid out of me and in an instant his tongue was back on my anus. He licked me some more and after that he slowly put his middle finger inside of me. He went in slow and in little steps. It hurt a little bit but after he put the whole finger in the pain subsided after some time. He let it rest inside of me got up quickly and pulled his pants and undies down with the other hand. He sat back down and slowly fingerfucked my ass with his middle finger. It felt weird at first but after some time I got used to it. He did it some more and after that he slowly pulled his finger out of me. He reached back into his backpack and got some lube out. I didn't see it but I now know what it was. I assued he put some of it on his dick. He then stuck his finger inside of me again but now it felt really cold and watery. He spread it around inside of me pulled his finger out and put some more around my anus. Pete then told me to slowly lean back and sit down. I did as he told me and both of his hands spread my cheecks apart while slowely lowering me down onto him. He guided me and stopped when the tip of his dick hit my anus. He told me to relax and slowly sit down. I needed to push myself down a bit because the head of his dick was a bit wider as his middle finger. It hurt a bit until I had the whole head of his dick inside but I went slow and carefully. Pete told me that I was his best student and that I should slowly continue until sitting down completely. I tried my best and after some time eventually petes whole dick was inside of my ass. Luckily pete's dick was on the smaller side and so it only hurt for a short bit. So I was sitting on his lap again with his dick inside of me. His right hand wrapped itself around my still hard dick again. He told me that I was doing a great job and asked me if it felt good and without lying I agreed. He pulled his hand back grabbed my waist and made me bounce a bit up and down. He again asked me if it hurt as I told him that it felt okay. We then played different songs in this position for about 45 minutes. When his dick would get softer he would make me bounce on him a few times and he was rock hard again. Pete then pointed at the clock and said that we needed to wrap it up and that it was time for the finale. I stopped playing and he pulled my upper body back leaning against him. He then wrapped both arms around my stomach and told me to try to bounce up and down. After some instructions I got what he wanted from me and bounced on his cock while his arms were still wrapped around his stomach. I did that for a few minutes until he calmy told me to bounce more up and down. It didn't take long of my doing that until he pulled my firmly down breathing heavy. He let out a big long breather with a bit of moaning. I felt his dick inside of me lightly jumping and twitching before I felt hot spurts of cum filling my insides. Thinking back he had an enormous orgasm I think telling that he shot a good 6-10 spurts of hot goo inside of me is no exaggeration. "Don't move" he let out under his breath while his dick was shooting and pumping the last spurts of semen inside of me. He was breathing heavely for some time and after that he said that this was what he meant by becoming one with the teacher. I sat there with this hot almost burning goo inside of me. And he once again asked me if it had felt good or bad. I answered Pete that it felt good and that I liked it. We sat a few minutes like that until he went limp inside of me. Pete then asked me to slowely get up. I did as he told me and while doing that I felt a nearly endless stream of cum dirpping outside of me. And that was the first time my piano teacher used me or better said used my ass. I went to Pete's private class until the age of 16 so I have a lot more stories to tell. He shot a whole lot of cum inside of me over the years and he almost did it weekly. Pete made me shoot my first spurts of cum aswell some time later and there was a lot of oral sex aswell. Tell me if you would like to hear more.
