Story Scribbles

These are a couple of rough ideas I've had for stories recently. Leave a comment to tell me which one would make the best story. 
 
Amy's Balloon Journey
 
8 year old Amy had had enough of being stuck on the ground like a stone. She wanted to be just like her toy balloon, floating, practically weightless in the sky. And she was going to do just that. She held onto her balloon tightly, took a deep breath, and her torso swelled, just like a balloon. She expanded until she was a perfect sphere. And she then slowly rose up off the ground, weightless like her balloon, and into the sky. 
 
What a Peach! 
 
"I have something to show you, Mario" said Peach seductively. Mario just stood there, bewildered. Peach had something for him? Slowly, the princess inhaled a deep breath and placed her gloved hands underneath her breast. Mario then had to pinch himself as he saw that the princess' chest was actually starting to grow. Peach held her breath, and her breasts grew bigger and rounder and bulkier.
