set a timer for your sub for 10 minutes. tell it it has until the timer goes off to make itself cum. if it doesn't cum in that time, it doesn't cum at all.
record the amount of time it takes to cum. set the next timer for that amount of time. see if it can beat its own record.
repeat. and repeat. and repeat. how fast and pathetic can it be? how much can you ruin it's stamina? can you get to the point where it cums within mere minutes of being touched? seconds?
once it's trained like this do away with the timer. start employing strict punishments for cumming too quickly/without permission. you've primed it to fail.
you're welcome.
