He busied himself rummaging, as Rhonda sheepishly came out of the bathroom. "So.. um... can I leave now?" She made for the door.
Lou's arm snaked out and grabbed her slender arm, easily keeping a hold of her teenage frame. "Hmmm... maybe one or two more changes, huh? How about this?" He used his other hand to proffer a little sachet of powder with a label on it. "Maximaximus gluteus? What's that?"
Rhonda tried to pull away feebly. "C'mon, you said I could go!" she said, despite herself, sounding like a petulant teenager. Lou shook his head.
"C'mon, just a couple more things." Ignoring her pleas, he opened the sachet and chucked the contents in her face, letting go of her arm.
Rhonda coughed and spluttered as she felt a warmth rush through her nasal passages, down through her stomach and intestines and suddenly... "Owie!" she yelped, grabbing at her ass as it began to grow and grow, becoming enormous. It hadn't been small before, but now it was wildly disproportionate, looking like cartoon hips, something no one alive ever naturally had. It only finally stopped with her buttocks each bigger than one of her already sizeable breasts, hanging off tree trunk hips.
