First Date Chapters 1-3
"Let's talk about your chastity belt a little more" Nikki whispered in your ear. Maybe it was the words, maybe it was her breath in your ear, maybe it was her fingernail that refused to stop on your torso, but your cock was suddenly straining madly against the constraints of your boxers, and you were dying to talk about whatever Nikki wanted to talk about.
"If I'm the only one that can unlock you, that means that I get to decide how long you're in it. Right?" You nodded. Yes, that sounded good, please touch my cock! "But I wouldn't want to be mean, or do anything you don't want, so we need to talk about how long I'm allowed to keep you in there. I mean, could I keep you locked for a whole week?" Yes! You nodded in confirmation, as Nikki smiled beside your face.
"I thought so. What about for two weeks?" Yes! She grinned even bigger. "I'm really glad to hear you say that. You know, while we're talking about this, I want you to do me a favor. I want you to think about my panties."
