Natalie J Robb found her raunchy 'Emmerdale' sex scenes "brilliant".
The actress - who plays Moira Barton in the ITV1 soap - saw her alter-ego cheat on husband John (James Thornton) by sleeping with arch-enemy Cain Dingle (Jeff Hordley) during a moment of madness, and admitted taking part in the saucy storyline was "easy".
One of the sound guys was really embarrassed because he was right next to us while I was snogging Jeff.
She told BANG Showbiz: "It was brilliant doing the sex scenes. Jeff was really good to work with, he made it easy. The director choreographed it all. It was quite racy! Luckily, it was a double episode so they were able to go a bit further than usual.
"One of the sound guys was really embarrassed because he was right next to us while I was snogging Jeff."
Natalie's co-star James - whose alter-ego John has shunned his wife from the family following her betrayal - explained sex scenes are often more embarrassing for the crew than the actors involved.
He said: "Sometimes it's more embarrassing for the crew because they don't want to get caught clocking anything.
"I've done scenes before where I've been stark b*****k naked and had to walk across a room in front of an entire crew, who are hiding behind their hands. The last thing you want is to look up and see the sound guy staring right down there."
Natalie and James will star in Emmerdale's Judgement Day storyline - airing on ITV1 at 7pm and 8pm on December 8 - which will see six characters accused of attempting to murder Cain.
