Married couple Ashley and Tanya are seasoned swingers, but there's one boundary the Leeds couple have never previously crossed - trying to seduce and have sex with other people on their own without the other one present. After nearly walking out of last night's social, Jamie and Sharmayne still aren't sure how far they can go, so non-monogamy coach Effy orchestrates a sexy pool party to help them loosen up. After a cocktail date with resident couple Jen and Marc, they're forced to make the ultimate decision.
