The cage is not only keeping you from cumming. It is teaching your body where that energy is allowed to go. Every time you get hard against the bars and nothing happens, the urge does not disappear. It moves. You take it to the gym and you lift until your arms shake. I want that frustration turned into weight on the bar, into another set you would have skipped before. Your mind gets quieter when your cock is useless and your muscles are not. That is the modification. Locked, hungry, and stronger because I decided the energy had somewhere else to go.
