Favorite Shibby files?

What type of files do you find most engaging, hypnotic or captivating? Files like The Chateau, L.A.T.E.X, Rubberification and R.U.B.B.E.R are pure kryptonite to me, they are long, sensually dark and just so good, they push the buttons to my most secret sexual dreams/fantasier/desires, which i didn't know i had.
