That's an awesomely sexy picture, you can see her jeans have definitely been filled with something, the trunk area is full and it's working its way down her upper legs, but whatever it is hasn't yet soaked through the denim. I would have guessed custard but I think she's played in that before? M'lady loves treacle and syrup for clothes filling, not as cold as custard and feels silky as it flows inside her swimsuits, hence guessing molasses, which I gather is like a runnier version of treacle.
Well, mystery no more... this clip drops at midnight, so I figure you all should get a sneak peak for participating! Here's a link to the trailer, plus some pics:
