extended wear electronic stimulation and locking unit for chastity

Has anyone found experience with or come across a long-term wearable chastity device that integrates locking and ESTIM? I’ve seen the Zeus, but it seems more suited for short-term play.

I dream of a secure chastity unit designed for extended wear that combines electronic stimulation technology to deliver both pain and pleasure (with pain inevitably becoming dominant).

On a related note, I’m also drawn to forced repeated orgasm torture. To me, mixing sensation with denial alongside forced multiple orgasms creates the most delightfully masochistic experience. However, this would likely need to be handled by a machine, as MrHappy tends to lose interest after a few rounds and won’t remain hard.
