Clear Ball Crusher Vise

I need one of these!

What do you mean one finger isn't enough?

I did a tease and denial session the other night and after close to an hour of begging for release, I allowed my sub one drop of lube and one finger to work with. "What can I do with only one finger?!" he asked desolately. I just cackled and encouraged him to get creative. It'd only been four days since his last orgasm. Light weight! I didn't feel he deserved to cum again so soon.

My male friends say this was cruel, but hey, at least I allowed him to touch himself at all. See? I'm so nice!

What's the longest you've gone without cumming or forced someone to go without? Is there a universal average "unbearable" point?
