As Sally approaches, Matt quickly runs around the side of the house, out of her view and calls for the wand to return to him. He wishes for the powers of the wand whether or not he has it in his possession. Then he wishes for the wand to go back to his father's room.
Rounding the corner, Sally is almost upon him, and ready to pick him up. Quickly he thinks, 'I wish she were 1 foot tall'. Immediately Sally dwindles. Her pants fall to the ground and her shirt looks 5 sizes too big. It slips off one shoulder and she struggles to hold it up with one hand. Her bra shows on her exposed side, and it does not even make contact with the side of her body anymore. Finally the weight of her clothing becomes too great, and she is left naked in a pile of shirt, bra, shorts, and underwear.
Matt quickly shrinks himself down to her size and steps over to her. "You see what's happening!", he says. We're all shrinking out here. Brett walks over to meet them, standing at 6" tall and half their size to confirm the statement. Sally, in a state of shock, screams at the sight of Brett. "Oh my god!!!", "Brett, you were shunk too, AHHHHHHHHHHH!!!" Matt considers this as good a time as any to shrink them all down to 6" tall, and Sally recovers her senses in the meantime.
"My god", she says, "I'm naked!". Her small breasts and skinny body were obvious to the world. Originally she was 5'3" and 94lbs, but the height differential was at least taken care of. She lifted some of her shirt fabric to cover herself from the two boys.
"I think we have bigger things to worry about Sal" Brett said, gesturing towards the towaring world around them. "Besides, we're all naked." Brett said with a blush. Both he and Matt had obvious erections.
