Earn or regret cumplay.
 

Simple hopefully, you flip a coin

Heads = earn
Tails = regret

If earn you must complete a task BEFORE you may cum.
If regret you must complete a task AFTER you cum.

The person above leaves the before and after tasks for the next person.

So for whoever posts next,

EARN - you will have to edge 3 times a day for a week prior to your next cum.
REGRET - you will have to wear your cum on you for a minimum of 1hr after you've cum. (Preferably on face or in your underwear)
