I've experienced a variation of this in private play some years ago. We played a game where while securely restrained I was ordered not to cum for 10 minutes and then subjected to intense stimulation with fur, fingers and a Hitachi magic wand. Failure resulted in being force fed the cum, caned on my inner thighs and then left for an hour in sensory deprivation. At the end to the hour the process was repeated. Play continued until I was completely spent and thus able to successfully endure the 10 minutes without climaxing.

Fond memories but I absolutely hated it while it was happening.....definitely involved elements of CNC.

She called the game "If at first you don't succeed....."
