Erika feels a itchy tugging comming from her panties. Not thinking too much about it, she reaches back to scratch at it. But what she felt was a knob petruding from her tail bone!
Running to the mirror, Erika flips up her skirt to find a small red tail sticking out above her panties. She could only watch in awe as it grew larger and more full. Squeezing and petting it, it started twitch. With a final tug, it finally stopped growing.
Erika can only look at herself, a young cute girl with a fox tail sticking out from under her skirt. Moving the tail back and forth she finally got used to moving it. "Well" She says to herself "It is cute."
