As she was leaving the store and getting into the taxi she got a warm feeling in her crotch area but she just brushed it aside. She had decided to go home and get ready there.
When she was there she got the same warm feeling as before only stronger and this time she didn't push it aside. Her mind started to get clouded with ideas of her having a furry body and a dog's tail.
She then realized that the warm feeling was her getting incredibly horny. So she decided to go fur all over her body with long and softer fur covering her pussy. She gave herselfd of ears and a tail and enlarged her breasts and ass and added three sets of two of smaller breasts down her tummy.
