When it comes to sex it is usually over when the man cums. I think to be a better lover to your wife or significant other you remove your orgasmic pleasure from your sexual play.
For me the chastity cage is an added security that I will not be overcome with my desire. Knowing that there is no chance of having a orgasm allows me to focus more on her pleasure.
I love when my wife gets in that playful mood. She will lock me up on a Friday morning. I may stay locked up until maybe Sunday afternoon or whenever she feels like it.
What she gets from me when I am caged are foot rubs, massages, pedicure, toes painted, I shave her legs with other parts that need it, and of course as many orgasms as she wants. She also has the peace of mind knowing that she doesn't have to focus or worry about pleasuring me. She is free to make it all about her.
What do I get? Well, I am jealous that she gets to have a orgasm, I am envious of that post orgasmic glow she gets after cuming hard, and Constantly seeing the key to my cage around her neck is humbling. To be honest I can't seem to get enough, because there is something about pleasuring her repeatedly while being denied that rattle's my caged lust and I love ever second of it.
