I was 10 when, out of overwhelming curiosity, I came home after school on the one day a week the house was empty, found my sister's dance bag and changed into my sister's dance leotards and tights after first putting on a pair of her silky panties. I had about an hour or two that one day a week to mince about the house and admire my girlified image in every mirror and enjoy the feel of the panties and the leotards on me. Been hooked on them ever since.
