Boys tend to think that they can use their dicks to penetrate everything, but actually I prefer to penetrate them. They have so many holes that need to be filled and when I have a specimen strapped down I love to fuck their little urethras with my metal sounds. They need to be fastened, then I inject some lube into their peehole. Next i take my first sound and slide it in.
