You wake up, tied tightly down in your owner’s experimentation room. I tell you that I'm going to make a few alterations to your physique - whether you like it or not. I want to turn that ugly cock of yours into a gaping pussy. So I'm going to shove these enormous metal urethral sounds inside of it until that little hole of yours can't close anymore. It will take some intense training and modification, but soon, I'll even be able to fuck that little slit of yours with a dick! Goodbye dick, hello cock-pussy!
