Oh No! It's Time!

she then starts to feel her head pounding as she feels the transformation kicking in

I'm... Ch-Ch-Changing... It's... H-H-Hap-p-p-pening!

Her body grows bigger and muscular, her wings grow bigger and longer, her teeth grows sharp, her claws come out of her hands as her hands grow out of her gloves tearing them apart, her uniform becomes too tight as it starts to rip and tear apart off of her completely, her feet grows out of her shoes, her hair growing longer and thicker, her body feeling savage and feral

NOOO! she then changes into a savage feral angry Werebat ** HHHHRRRRRRRRRRGGGHHHH!!!

As the transformation is complete, she now stands completely big and muscular. Now a fully Werebat. Her wings bigger and larger now, her uniform torn to shreds

Me feel stronger... Me feel powerful... Me Feel Savage!

she turns towards you

You love what you see? she says in a feral savage sexy voice
