I thought we could all post various chastity games here. They could be real ones you use all the time or just fantasies. My hope is that this becomes a very long post as everyone adds there ideas and becomes a very interesting read.
So to start:
a dice game variation. KH rolls a die (or dice how many is your choice) I'll use one standard die as an example. KH rounds the number to the nearest even number, so 2, 4, or 6. the belted one doesn't know the number but knows the rules. on each even day of lockup the belted one ins unlocked and teased mercilessly for a predetermined amount of time (I use 10 minutes) then the KH tells him if this is his day or not. so he has to endure the teasing without knowing if he gets to cum or not.
Variations: on day 6 (if it goes that long) KH flips a coin to see if he comes that day. Heads yes, Tails no. that way the belted guy never knows for sure what day it will be.
I did this once and the effect was quite powerful.
