Those panties are probably naturally see-through but when wet, they are gloriously see-through shaping the vulva with wonderful precision, ( i think the official term is ' Camel toe ' but never having studied a camel's foot to any degree, i can't comment on the similarity! )

I'm also a heavy user of mustard but i've never bathed in it before.

Before i finish here, i'm still waiting patiently for exactly this kind of wet look setting , only with a full lacy slip rather than a chemise. I can't believe that i'm the only one with an appetite for this scenario. Annabelle always ignores my pleas so i'll try and appeal to John this time.
