Crossdressing Story From Boy to Girl35

I could just see my bra showing through the thin material and I hoped this would meet with mum’s approval and not look too sexy for a second adventure out into town. Wrong.
Mum saw me and thought it was really inappropriate for a GIRL of my age to be going out in such a provocative top. GIRL!. “But mum I’m not really a girl yet, but I have to look the part and I’m sure most other young girls of my age would wear something like this.
“That may be,” said mum, ”but you are not coming into town with your bra showing through in such a sexy way. I thought you wanted to avoid the attention of boys. Go upstairs and put on that full length slip I gave you to wear under your blouse and hide your bra.”
