A month long book that has daily instructions from a dominatrix to a lowly chastity boy. Being your own key holder, you are led in daily exercises on what to do and how to do it. No peeking to the next day until it cums!
A self-control challenge with daily instructions/challenges. I didn't make it my first try I only made it to day 10, so I haven't read all the days. I'll be trying again some month, maybe next Loctober.
