"Hey babe theres something I'd like to try. This is a chastity cage. Have you seen one before? Ohh nice. So its a bit of a fantasy of mine to be locked by you so that I'd have to earn my release? Would you like to try?"

"Lol no it won't hurt. I've tried it before solo but I just get horny and open it hehe. Let's do something. If it hurts I'll tell you and we stop it, right?" (You can also use a safeword if you have done it before)

Then use it for one session. Have regular sex with lots of foreplay. Oral is a must. Make her feel how excited you are. Do lots of sexy begging "oh pleeeeaseeeee Im so hornyy". Then if everything goes right ask her how she felt and go from there.

Honestly this works for pretty much every single kink.
