Of course the primary purpose of the chastity device is to keep you from achieving orgasm. Stopping you from wasting time playing with yourself when you could be spending time worshiping Me.
However, that isn’t the only purpose of a chastity cage. It can be used for punishment as well.
There is something in the knowledge that the sexier a Woman dresses or acts, the more it tortures some little chastity bitch.
Knowing that every time She moves seductively, a twinge of pain courses through his body, originating at that locked away little dicklet.
Simply by being the beautiful Goddess that She is, She can torture and ruin him, until he is begging to do anything to please Her.
To add insult to injury, allowing him to only pleasure Her with his tongue makes the torture all the worse…
