She slid the bar down. She wasn't sure exactly how young she wanted her skin to be, so settled on 9. But this wasn't what she intended as all, as she began to shrink again, and her breasts as well!
Her legs became coltish and slender, her hips narrowed, and her body hair simply vanished as she regressed back into late childhood. Her hair lightened in color, and her breasts shrank, but they didn't vanish, leaving her a girl of 9 with a B-cup, which looked quite huge on her. Her breasts didn't droop or sag at all, and they barely jiggled, so young and tight was her skin.
She was also even smaller, having lost a good 7" of height. The towel was huge, and seemed more like a blanket!
She giggled again. This was fun! She knew she looked ridiculous, and she felt top heavy. She really should change back to normal, since her mother would be home soon...but she had a better idea.
