Clamps. You all have them, useful for all kinds of projects. This project will take more than mere time. I will instruct you on how to use this clamp initially as a sharp and efficient cock cage. After that a sexy little tease from me, this should make your cock twinge with excitement. That is what I am counting on. Because when you get hard your member will be pushing against a circle of small plastic edges all around the base of your cock. Don't you dare take it off until-or-if I say. Understand.
