After Jess had swallowed the last of vial, she looked at Mary. "So, what do I get to be?" She felt a little nervous. This was, after all, magic and something she hadn't believed in for most of her life.
"I gave you the beauty of the female body." Mary said. Jess frowned, did Mary's voice sound off? Deeper maybe? Her thoughts were scattered as she felt a tingling all over her body.
"Quick, quick, take off your shirt!" Mary said, her voice noticeably different, but Jess wasn't paying much mind. Her attention was on her own body, the magic of the vials was apparently working, if it wasn't just some buzz. Jess took her shirt off and looked at her mildly skinny torso.
The tingling intensified, and Jess watched in fascination as her body began to noticeably change. First her skin softened to such a point that it became silky smooth. Then all her freckles faded and her pigmentation became an even light cream color. Jess gasped as she felt and watched her breasts swell in size and pertness and strained inside her bra. She quickly reached around and unhooked it. With a sigh of relief Jess's breasts perked up with out a constraint. Jess's changes were over soon. She had become a more idealized and beautiful version of herself.
She looked over at Mary, who had been momentarily forgotten, and received a shock. A very manly man sat where Mary had before. Rugged good looks and muscles had come from Mary's own epitomized femininity.
"Well," Mary said, in a deep gravely voice, "what do you think?"
Jess quivered for a moment, sat back and put a hand to her forehead. Things were getting very odd now. She did like her changes, but she wasn't sure about Mary's. Things were happening a little too quickly.
"Give yourself a chance to get accustomed to this. You'll be fine. Trust me" Mary said with a handsome grin.
