First Date Chapters 4-6
Nikki dropped down on the couch, gently caressing her tits with one hand. "So that's the magic formula. One of these long fingernails. I can unlock your cage, and slide it off. As your cock quickly swells, which I'm sure it will, I can take just one fingernail, and drag it over the top of your cock. When your cock jumps, and I'm sure it will, I'll be ready, and I'll jerk my hand out of the way. That wasn't the deal, remember?"

I'll use just the very tip of that one fingernail, and trace it all over your cock, as light as I can. Whenever your cock swings or jumps, I'll be out of the way. And once it relaxes again, my fingernail will be at the bottom of your cock, right at the base, and trace all ... the ... way ... up ... to ... the ... tip... nice and slow, and extremely lightly."
