Just my constructive feedback/opinions. I was hoping there was going to be a bit more depth to this story, more kinky play, as the beginning had promise. The premise of an all-or-nothing chastity was interesting to me, but I found the idea of your story to be more torture for torture sake; and describing the modes/functions of the device itself. I would have liked to read about what the characters got out of their perspective dominance/submission as the female lead doesn't seem to 'get off' other than controlling her husband. Likewise I didn't get any sense of desperation for the husband to please his mistress/wife. Again, I thought this story has potential but would like to get into the psychological aspects of their relationship and how she gets her carnal desires fulfilled.
Cheers,
