Your gf becomes your keyholder - Chastity roleplay

Hey honey! Do you know what day it is? Of course you do... You've been counting them. It's been a week since I put your cock in a chastity cage, and today's the day I promised to unlock it. Except... I've changed my mind. You see, I've been enjoying this. I love how selfless you've been this past week, how focused you are on pleasing me. I want to keep that. So I've decided to keep that cock of yours locked up. Besides, you seem to enjoy being my little chastity slave... Doing whatever I demand of you, in the hope that I might feel generous enough to give back the key that's dangling between my perfect tits. I highly doubt that's ever going to happen, but if you're a good boy I might let you out of your cage occasionally. I'm not sure when yet, though. My toys and your tongue are more than enough to please me. So let's keep that cock of yours nicely caged. Being denied sex makes you a much better person, you know. And eh, about me being your girlfriend? Yeah, that's over. I'm your keyholder now.
