Sometimes I think about my niece when I m*********. Shes 12 but is developing very fast and shes always been a pretty girl but now shes growing into my sister-in-law’s body. I catch myself looking at her all the time especially when we all go to the family beach house. When shes not in her swimsuit, shes wearing super short shorts or yoga pants and I learned yesterday that she wears thongs now because when she bent over to tie her shoe, her shirt came up in the back and her thong popped out of her shorts like a damn whack-a-mole.
