Two women who took part in a sadomasochistic session with motorsport boss Max Mosley have denied there was any Nazi-themed role-play.
Instead, the witnesses - called "D" and "A" - told the High Court that what had happened had been a "prison fantasy".
Mr Mosley is taking legal action against the News of the World which alleged he had engaged in a "sick Nazi orgy with five hookers".
He is suing the newspaper for defamation and invasion of privacy.
'Offensive' description
Woman D, a dark-haired student in her 20s who cannot be identified, said the paper's account of what had happened on March 28 in a Chelsea basement flat was "absurd".
She told the court: "I am particularly appalled at the accusations that our scenarios had any Nazi connotation or overtones. No Nazi images, uniforms or material were used."
She also found "offensive" the description of her and the other women involved as "hookers and prostitutes".
On March 28, she said, she felt she was "amongst friends, doing something I enjoy and all those involved enjoy".
She added: "I would rather be doing CP (corporal punishment) a long way over going to the dentist."
She said she had known Mr Mosley for about 18 months, having met him at a party arranged by Woman A. She was introduced to him as "Mike".
"Since that first experience with the claimant I have seen him a number of times and we have forged a friendship," she said.
Cross-examined by Mr Mosley's barrister, Woman D denied that she was "financially dependent" on Mr Mosley, who is president of the International Automobile Federation (FIA).
'It is just fun'
Woman A, a well-dressed blonde, told the court she had been involved in BDSM (bondage, discipline, dominance and submission) all her adult life.
She said: "When I am being dealt with, just as when I deal with others, there is no maliciousness or anger involved - it is just fun, exciting, an endorphin rush."
Referring to Woman E, who talked to the News of the World and filmed the events with a hidden camera, she said she "was one of my closest friends before she betrayed me so horribly by going to the newspaper about Mike (Mr Mosley)".
Woman A described an earlier German prison scenario on March 8 as "hugely sexy and fun", and said she did not view it in any way as Nazi.
'Strong Nazi theme'
She denied she had told Woman E that the March 28 session, for which the five women were paid ?2,500 by Mr Mosley, would have a "very strong Nazi theme", or that "Mike" ordered one.
"I would not contemplate putting on such scenes which I would find distasteful and I would expect most people to be disgusted at the suggestion of a Nazi theme and respond similarly."
Woman A said the German theme arose after they heard Woman B speaking to Mr Mosley in German at a party at the beginning of the year.
"We said 'that's really sexy and horny and wouldn't it be great if we did a scenario like that', and then it went from there."
Shown a black and white striped top and trousers, and asked if this was the uniform she had purchased for the "prisoners", Woman A laughed out loud and said: "Is this the one? I'm not going to try it on."
She denied that the costumes - hired from a joke shop - had been intended to replicate concentration camp uniforms, as the newspaper suggested.
'Abhorrent'
Earlier Mr Mosley said that at no time did he or Woman A, who arranged "parties" like the one on March 28, ever use the word Nazi in their discussions.
He said that a Nazi theme would have been "abhorrent" to him.
Mr Mosley also denied the convict uniforms worn during the session had a Nazi theme.
He said: "Had I wanted a Nazi scene, I would have said I wanted one and A would have got some of the inexpensive Nazi stuff from the joke shop that provides uniforms and would not have gone to Marks and Spencer and got quite expensive jackets."
Mr Mosley told Mark Warby QC, for the News of the World, that the head-lice checking and shaving involved in the scenario was "the kind of thing these people do all the time".
He said: "I had never had lice-checking before but went with the flow. I didn't find it particularly erotic."
'Harsh-sounding'
Mr Mosley, the 68-year-old son of the 1930s Fascist leader Sir Oswald Mosley, agreed that he had spoken in German during the session.
But he said this was not for any war-related reasons, but because it was a language that suited his dominant role.
He said: "German also somehow sounds appropriate for a bossy, dominant character. It is a harsh-sounding - rather than a romantic - language."
Mr Mosley says that his life was devastated by the News of the World story and is asking for an unprecedented award of punitive exemplary damages.
News Group Newspapers, which published the News of the World, is contesting the action, arguing that publication was justified in the public interest.
