Okay but imagine having to earn your orgasms by completing tasks your dom sets. And maybe at first they're pretty innocuous, ie drinking a set amount of water in a day, maybe finishing a book left half read for months on your coffee table. Slowly though, it builds into bigger tasks. Not wearing underwear while running errands, wearing an outfit you bought on impulse but found too revealing to confidently wear. And there's never any push from your dom to complete it quickly, after all it's your choice to not want to cum, isn't it? It doesn't stop there though, without realizing how far you've gotten, you end up going even further just to get one orgasm. You take a nude at work, maybe after that you buy a chastity device. Still within reasonable boundaries. Then things really start pushing those boundaries once you agree to give them the key to the chastity device as a task. Maybe at this point you had pushed off making a decision at first, until eventually the desperation to cum fuels you to just give in. Once the pleasure of that orgasm fades and you're locked back in your cage or belt you start to realize how far this has gotten. But that's still not the end. Now they are trying to mold you into their perfect sub. Maybe it's getting an IUD out to be bred, maybe it's downloading a dating app just to find a next to stranger's cock to suck. Any fight you have against the task is met with a shrug and them saying "if you never want to come again, that's fine by me". But they know eventually you'll break down and comply. Just to be unlocked and brought to orgasm. At this point you know that the next task will be an even bigger ask. Eventually you lose yourself in completing the tasks, and end up the perfect sex toy for your dom. Maybe then they'll give you easy tasks again once you're perfect to them. Or maybe they'll give you an impossible task so you never cum again.
