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 tanned blonde heaved in a deep breath, her orange sports top stretching as her breasts and belly billowed out to beach ball proportions.  Another breath and her ass and limbs bulked up, their sudden width and conical shape forcing them out to the sides before a third breath simply pushed her body out in all directions, leaving her as a six-foot balloon with two domes on her front and the vaguest implication of human anatomy.

"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.

While Dani DeGrassi had her start in the family business, there was no denying that she went far beyond anyone's expectations. Scant years after graduating with two degrees, she was the owner of several businesses, one international, and involved in a variety of foundations dedicated to the arts and sciences. She had a singular presence which tended to leave a deep impression on everyone she met; most people described her as "unique." Others, with a better grasp of language, more correctly described her as "deeply eccentric."
