‘Open House: The Great Sex Experiment’ bosses have "upped the ante" for its second season.
The saucy Channel 4 documentary series is getting another run and “will be far bolder” by exploring throuples and teasing an 18 people strong orgy.
A source told The Sun newspaper’s Bizarre TV column: “Bosses have really upped the ante this series. Viewers will definitely see the difference as the upcoming version will be far bolder and push the boundaries further. The sheer numbers involved in the orgy is likely to be a TV first.”
The show - which was made at a plush country home - will feature a load of “sexually liberated” singletons join in with already existing polyamorous relationships.
Casting is underway, with bosses at production company Firecracker looking for people to take part.
The application page reads: "Do you fancy taking part in 'Open House: The Great Sex Experiment'?
"Are you part of an adventurous couple who want to explore opening up? Or would you like to be one of the retreat's single residents?"
Producers are looking for people to join "in any potential future series".
The page continues: "In this bold concept, committed couples come to a luxury retreat to test whether opening up their relationships and having sex with other people will strengthen their bond... and the show's producers Firecracker Films are looking for participants to take part in any potential future series."
Announcing the second series last year, Channel 4 Commissioning Editor Tim Hancock said: “The popularity of Open House shines a light on just how many couples nowadays are considering alternative relationship models and I was proud of how the series showed both the joys and difficult challenges that opening up your relationship brings.
“We’ve been blown away by the number of couples who have applied to come to test out non-monogamy in series 2.”
