"So you can inflate?" she asked me.
I nodded. "Absolutely."
"Okay, but... how does it work?"
"I just breathe in." I demonstrated, the air swirling and filling me. My gut surged out, my backside and chest following immediately after. 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.
