Challenge Coin Tasks
Challenge Coin Tasks are the things you have to do to fulfill your obligation to the cadet who gave you the Coin. Mine was to ask each cadet in my graduating class if I could suck their dick and swallow their load while I jacked off and blew my load.
When I go to the cadet showers every morning, I look for guy's who haven't taken care of their morning wood and are walking around with raging boners. Then I fall to my knees in front of their hard-on -- they usually say "go for it!" - I do and complete one of my Challenge Coin Tasks!
