A Channel 4 series paid adult content creators to romp with contestants - but hid their backgrounds from viewers.
The Mail Online reports that producers for Open House recruited single women and couples with a background in making pornographic content to have sex with couples who were interested in expanding the boundaries of their relationships.
The pretence of Open House: The Great Sex Experiment is "committed couples come to a luxury retreat to explore whether having open relationships and sex with other people can strengthen their bond".
