No access at all!!
Chastity and diapers, best thing for a slave.
The most effective way to stop chronic masturbation is to lock his tiny dick in a chastity cage.
We were on a break from our chastity game until my wife found a femdom chastity caption on her laptop yesterday that must have downloaded when I was browsing porn recently. She is very angry with me and told me I need to be locked up again as a punishment. Back in the cage!
Locked up best thing for you.
