Housemate Harry Amelia of the UK Big Brother show has done porn in the past. As it turns out this outspoken, often confrontational member of the show was on a porn site called Lady Voyeur in which she watched a man masturbate in front of her while she gave him "something to look at" and then berated him on the job he was doing.
Lady Voyeurs is a CFNM (Clothed Female Naked Male) porn site where the fully clothed (though sometimes scantily) women watch nude men jerk themselves off for the ladies enjoyment. It harkens back to the days when you might have been caught masturbating by a sister, or a friend, who then wanted to see you do it all the way to orgasm.
Asked about her forays into the porn business her housemates were mostly okay with the idea. Only a few of the women gave the typical answer they most likely thought their parents would want to hear, while some of the others were looking up the site trying to find her while being interviewed. No doubt the men retreated to private areas of the house to masturbate to their new found porn friend.
