As Jeff stood there conflicted about what to do next, his now grown up former little sister walked over to the refrigerator and took out a carton of milk. When she turned her back to him and poured herself a glass, Jeff couldn't help but stare at her long curvy legs and firm behind, both accentuated by the tight pair of blue jeans she now wore. As much as he hated to admit it, he was hopelessly turned on by her adult body.
She put away the milk carton and took a long sip of milk.
Milk...
Jeff smiled as an idea came to him. He knew just what he wanted to change her into, all thanks to the milk.
