Does a free session ever become invaled after time?

I would say yes as long as they use it within the year. But let them know it cant always be right when they call and they expect you too be free too see you at the drop of a hat. Also keep in contact with the provider don't wait 6 months are up to a year before you contact her or try to call her.

Tara, remember that promise you made to me last January 14th?

Yes I do my love? Do I need my spankings if I don't remember all of it?

Of course you do, but I promise to be gentle, mostly, and then will kiss the pain away.

It should only expire once she retires.

But hell, with all of the retiring and then UN-retiring around these parts...LOL
