The thrill she gets from exposing herself is immense, she gets a charge like no other at having him watch her. So much so that she extends things, exposes herself more and more to him and revelling in the heady sensations and powerful orgasms she receives in doing so. Then comes the time to extend the game again, to put it into practice and to have him watch her close up. Once that is achieved then sex obviously follows, but on her terms and not his. She will tell how it will be and, that is exactly how it will be.
