I wanted to share something a partner of mine came up with that allowed for a very easy introduction to chastity play. It's a kink of mine that she hasn't explored yet but is finding to be a lot of fun and quite hot. We are also both poly which can make chastity play a bit more complex. We are also both switches that lean towards the bottom side of things. What she came up with was simply asking me to notify her when there was a status change in me being locked or not. I also agree to what we called "slut rules" in that I would only orgasm with other people and that I wouldn't get myself off. Online with other people didn't count either. That's basically it. After a week of this we both found that we were thinking of each other quite often and that by freely volunteering to put this device on for her repeatedly it was showing her what I wanted and offering my cock and orgasms as a gift to her. We sort of stumbled into a submission that was freely offered and graciously accepted.
