It is no secret that Shego absolutely adores Tara with every fiber of her being. That being said, being the ultrasexual and mischievous woman that she is, Shego likes to have fun with Tara.
Case in point; Shego pulling down the top of Tara's pink dress to exposes her glorious breasts. Can't you just imagine Ron almost getting a nosebleed from such a scene? 😆
