The name is de Sade. Catherine de Sade. As in Marquis de Sade, the 19th century French revolutionary who advocated total sexual freedom, no matter how kinky it got. Catherine is definitely an advocate. One of her hobbies is going into peep-show booths and sucking off strangers through glory holes. And her definition of a recent five-way she had with four guys? "Eight or nine guys is a gang bang. Four is more like a nice get-together." We asked her if she has any other fetishes, and she answered, "Do you have a few hours?" We asked her about her sexual fantasies and she said, "Yes, and they usually involve multiple people. Lots of bondage and captivity situations, too." Get the picture? So what is Catherine doing on the 40Something.com site? "Something most women won't do," she said. Catherine is a fitness buff, and she works out every day. "I like to have a lot of high-energy sex, and to do that, I have to look right and be in good shape," she said.
