My sweet sissy girl is growing up! And today is a very special day: it’s the day you’ll be graduating from diapers into big girl panties. So exciting!

I know the transition out of diapers is a little bit scary, but don’t worry, I’ll show you just how to enjoy all the new feminine treats that await. A cute training bra, pretty panties, a nice pink dress, and a diary to write about all your boy crushes in. We’re going to have so much fun together! Who could be better than your big step-sister to initiate you into the big girl club?
