The good news? She's doing to unlock the cage and let you squirt on her stocking covered feet.
The bad news? You're going to lick up every single drop.*
* Why is that bad news? Because the fantasy of cleaning up your own cum is much different than the reality. The fantasy, before you cum, when you libido is high, sounds wonderful. But after, when you squirt, when your libido crashes? Well, that's when you do it because you were told to, not because you want to.
