Here is something that I've found on Deviantart by a talented 3D animated named AnAlternateUserName. He is mainly known for his GTS work but this time he did something a little different.
This animation technically is GTS as well but since we don't see her grow taller in this and it is body expansion I put it here as well. Check out his other GTS works and support his material (if you want).
