Little Sarah put her hand on the rock and said "Mommy, I wish you were a little girl, too, but even little than me!"
Little Sarah's mother suddenly felt herself shoot down in size. She could feel her breasts receding from inside her bra, and her panties and pantyhose drop to the floor.
She looked up at Sarah with dismay and was about to make another wish, when Little Sarah grabbed the rock away from her and put it up where Little Mommy couldn't reach.
"And now," said Little Sarah, tapping Little Mommy on the shoulder, "TAG! You're it!"
And Little Sarah ran away.
