It all started back when I joined band class and started playing Clarinet. I had quickly developed a fetish towards my Clarinet.
Well one day, I was practicing my Clarinet at home and started getting turned on by it. I had practiced my Clarinet for about 10 minutes and was already really horny. The more I practiced, the more I would pause to take a piece of clothing off. First it was my shirt, then my pants and soon I was just sitting in my underwear which had semen on it. I could tell that I was pretty hard.
I started to play my Clarinet some more and then took my underwear off. I was completely naked with my Clarinet. It felt a little weird to play my Clarinet naked, but I liked it. Soon I was unable to resist the urge and I started to slide my penis into my Clarinet's bell and moved it up and down a little bit. My Clarinet was so warm and wet inside. I took my penis back out a little bit and some of my semen was in my Clarinet. I then put my penis back in and started moving my Clarinet's bell up and down again. It was getting even wetter in there from my semen and even started making noise as I was getting faster and faster.
I couldn't help myself because it felt so good and then finally I started cumming really hard inside my Clarinet. I then got slower until I stopped and just had to sit there with my penis still in my Clarinet. When I took my penis out, cum started oozing out of my Clarinet. After that day, I would use my Clarinet as a sex toy after I would get done practising with it.
