My cock is locked in a tube that is lined with sharp, sheet-metal screwtips. When I get erect the tips dig into my skin which makes my cock begin to harden. The more I harden the deeper the tips dig into my cockflesh. The pain is excruciating and can bring me to my knees pitifully begging for release. Hope you enjoy my pain and shame. Please repost.
I willl post your nudes all over the internet
