Going Down

Rachel held the medallion, wrapped in a piece of cloth in one hand and a Barbie doll dress in the other. She placed the dress on George's naked chest and ordered him to put it on.
He was about to protest when he felt the cold metal of the medallion on his skin and knew what was about to happen.
He felt the familiar tingle from his first change and could feel his body stretching and shifting to change shape. When that was done he felt his bonds loosen and thought maybe he'd have a chance to get out of here. When they were loose enough he struggled to get up only to have Rachel's massive hand clamp down on his chest, holding him down and the dress and medallion on top of him. At first her hand just barely covered his chest and didn't seem to heavy but as he shrank he felt it get bigger and heavier until it covered his whole body with room to spare.
With no choice left, he gave up and let the changes finish, he would have to find another chance to escape, hopefully he would get the chance.
After several minutes he felt the bed stop growing underneath him and Rachel released her grip on him. He sat up and surveyed his now impossibly huge surroundings.
The bed was like a football field to him, the floor was about a fifty foot drop, and standing above it all was a giant of a woman, hands on her hips, looking down with a triumphant look of glee on her face.
He stood up and tried to walk on the bed but just as he got his footing, Rachel slammed her fist onto the bed near him and he tumbled. This made her laugh even more and she told him to stay there, she had a surprise for him.
She returned moments later with a hand mirror, which she held in front of him.
Looking in the mirror he saw that he was now an identical copy of what Sarah had become, down to every detail. It was weird, but although he was much smaller, he also felt taller than he was. Although he was now approximately 11 inches tall, it was true that at normal proportions he was indeed taller, in fact at normal size, he and Sarah would be close to seven feet tall, Barbie's proportions were never made to scale. This was something that even if he knew, would bring him no comfort as Rachel scooped him up and brought him over to Sarah, who was now concious.
"George? Oh no, not you too!" she cried. He noticed her voice wasn't squeaky anymore then realized it still was, he was just small enough to not notice anymore and in fact his voice was now squeaky as well.
Their reunion was cut short when Rachel roughly pinned him to the wall with one hand and with her other tore several pieces of duct tape and stuch him to the wall with Sarah. When she was done she stood back to admire her handiwork then went over to the bed where picked up the dress and medallion and put them back in her purse.
As she left the room she turned to the new twins and said, "Don't get lonely girls, I'll be bringing you some friends real soon.
