Lesson 17: Vice
In this method a fairly large vice is place around he testicles. It is important that a large vice is used or else the testicle will slip away even if they are tied down with a rubber band. The vice is tightened slowly until he cannot take it anymore. As long as you do not tighten the vice well past the point he cannot take it anymore this method as no risk to it. This is a perfectly safe and fun method. The only problem is that large vices are expensive.
