My experience has been f-2-f (thanks for the term J's blu) with some long distance. I find that I love orgasm control but I don't understand why anyone would go beyond 2 days.
Personally I think it is irresponsible of the Dom/me to ask for that. I want my sub/slave to be happy to be mine, not to wonder what the hell can be gained by this.

The worst experience I have had in the life did not come from subjecting her to too much pain but from having her blindfolded and cuffed into an uncomfortable position. I kept driving her further and further into sub space with many types of pleasure/pain exploits and she began to beg for release. I love to hear my sub/slave beg and so I told her no and continued, her pleading became intense and I just kept on. When she came she was crying because she couldn't hold on anymor.

I felt like shit that I who was supposed to be in control forced her to break my rule of no climax without permission. She spent 20 minutes sobbing about how she failed me. I tried over the next few days to make her understand that it was I that failed her.

Doms need to push limits but we also need to know when the limit is about to be broken and trust lost to some degree.

Just my thoughts
