M4F Whats the most painful task you've ever given a sub? And why not take it a step further

Hello calling all sadists here, I'm sure you've often been asked when first messaging a sub, "what's the most painful task you've ever given a sub?" Well next time it's asked I want you to think about the task you give me today, think about what the most painful task you've ever given a sub and take it a step it up, will send proof of course!
