As a Dominant Woman, with a Slave that is kept in Chastity 24/7, one has to be creative, to get Satisfaction when she has no Lover at the Moment. I solved the problem by buying a nice dildogag. It has 2 dildos, one big one on the outside for my pleasure and a smaller one inside for his. That way we both have fun, while he is still locked up in chastity.
