Wonderful progress and fabulous pics! Seems your wife is beginning to enjoy this sexy fun game. Thanks for sharing your fun in this thread.
That white top is so sexy - maybe encourage her to wear just tops like that around your place now [not layered under multiple other tops] and as the weather gets warmer to continue to wear just tops like that when outside your home, and then shopping, going out for casual dinner, etc. That might be a way to let others to enjoy the view and to expand your fun beyond sharing just with your friend. Of course, continue taking pics of her.

Do you take pics of her around your place at other times, like when she is in the bath / shower, drying off, getting dressed, etc? That might be a way to expand the situations where your wife is letting more being seen...
