Nice workout clothes. I wonder what her first exercise will be? :-)
Independent of the story, her expression in this pic makes me think of a scenario where a thin weak nerd comes into a gym seeking to bulk up and become an "alpha" only to fail so miserably he gets fairly quickly turned into a girl as the hyper-masculine magic of the gym drains his manhood away. This is the facial expression just after being freshly transformed: pure bewilderment.
That randomness aside, this looks amazing! Lol
I like your faces more.
