Jess, now wonderfully feminine looked over the box of vials. For a moment she couldn't decide, tapping a slender finger on her full lips. Then a label caught her attention. It was so odd, so different that she couldn't pass it up. She reached over and took out the vial marked 'Balloon'.
"What'd you pick?" Mary asked in a deep man's voice, leaning forward eagerly. Jess looked around and giggled, holding the vial close to her buxom chest.
"You'll see!" Jess giggled again and unstoppered the vial. With a last look at Mary, Jess drank the vial. Jess hiccuped loudly, covering her mouth with a delicate hand and blushing. "'scuse me!".
Jess looked down at her hand, at her fingertips. They looked different, brighter. The vial was working quickly. Her fingertips turned a rubbery peach. Jess touched her fingertips to her face and found them to be something like latex. She watched in amazement as the latex spread further down her hand and arm. She shivered as the latex overtook her body. Her delicate feminine body changed over to a smooth, shiny latex balloon. The latex finally moved up to her head, it felt like she was being pushed down into cool water. Soon, it was over, and Jess had full changed into a balloon girl. Her hair had even been changed to look like molded latex. She stood up but pushed off too hard, making her whole body rise a good foot in the air before she floated down again. She giggled and turned around, modeling for Mary. "Why'd'ya think?"
"Jess, you always were the airhead!" Mary said, and agreed he liked the choice. Now it was his turn to pick a vial.
