If you like what you see, please follow!

You and your girlfriend are out exploring an ancient temple when she finds what appears to be a mysterious container. You leave her alone with it for a few seconds, during which she opens it successfully, only to turn into a well-endowed sphinx. You go back to check on her, only to see your girlfriend, or at least what's left of her, in her new form.

"Uh... What has thumbs, big tits and can only speak in riddles?"
