WATCH THE BIZARRE MOMENTS UNFOLD: Bride and Prejudice's Nathan exposes Codie Lea's X-rated trick
The Gold Coast couple revealed some of their saucy bedroom secrets during a dinner party with other co-stars.
Earlier in the episode, Codie admitted she's always got sex on the brain.
"All day in my head it's been 'sex, sex, sex' and we get to dinner and it's 'wine, sex, wine, sex'," she confessed.
And at the dinner table, details of their sexploits just kept on coming as Nathan, 25, declared to the group: "Codie 'grapefruited' me."
"So Codie comes to me one day and says, 'I've got a cool trick', and I said, 'OK', and she's like, 'I need to turn the lights off and you can't look'," he continued.
"I ran into the kitchen, I grabbed the biggest grapefruit I could find, I've cut both ends off, I put like a hole in it," Codie Lea, 21, interrupted.
The table was noticeably dumbfounded, except for Jess, 38, who exclaimed: "Oh my God!"
Codie Lea and Nathan then suggested the other couples should at home to try it out.
"Don't knock it 'til you try it," said Codie in a piece to camera.
Nathan added: "I don't know what else can top it."
Bride and Prejudice continues on Channel 7 tonight at 7.30pm.
