Sydney gave a disparaging laugh as she looked me over, setting her hand weights onto the gym rack.  "I hope you don't think you can -really- out-grow me."

The armpits of my shirt grew snug on me as the denim of my jeans pulled taut across my legs, and mere seconds later I was a bulging, buoyant version of my old self. Not wanting to leave things half-finished I continued, arms and legs being forced apart before growing wider, then rounder, then being absorbed almost fully by my globular figure.

This first part concerns the first group.
