Max Mosley said he spoke German "because it suited his dominant role"
Four 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 - "D", "B", "A" and "C" - told the High Court that they had been enacting 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 Sunday newspaper for breach of privacy.
Witness D, a student in her 20s who cannot be identified for legal reasons, said the paper's account of what had happened on 28 March 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 28 March, 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 witness 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, witness D denied that she was "financially dependent" on Mr Mosley, who is president of the International Automobile Federation (FIA).
Witness B said that during the session she played a guard wearing a German Luftwaffe jacket, which she had previously bought at Camden Market in London to wear to a concert.
She had also worn a suspender belt, stockings and black patent leather high-heeled shoes.
Speaking in a German accent she said that "under no circumstances" would she have taken part in a Nazi-themed scenario.
She said: "I'm very upset and offended because it is an insult and offence if a newspaper equates German with being Nazi - my grandparents were not members of that party."
She said that Mr Mosley, whose real identity she did not know at the time, never suggested such a theme.
On Monday, the court heard an audio disc of a recording made by Mr Mosley of another orgy a few weeks before the one featured in the article.
Mr Mosley and a woman were heard shouting in German, giving orders and making threats. A woman's English voice was clearly heard begging: "But we are the Aryan race, blondes."
Cross-examined on Tuesday, witness B said that she did not "pick up" on witness A referring to "Aryan race blondes" during the earlier session, on 8 March.
'It is just fun'
Witness A told the court she had been involved in BDSM (bondage, discipline, dominance, submission and sadomasochism) 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 another woman, described as "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]".
Witness A described an earlier German prison scenario on 8 March as "hugely sexy and fun", and said she did not view it in any way as Nazi.
She denied she had told E that the 28 March 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."
Witness A said the German theme arose after they heard witness 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", witness A agreed, but laughed out loud when asked by David Sherborne, junior counsel for Mr Mosley: "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.
Witness C, wearing a black suit, also denied that the event on 28 March had been a "Nazi scenario" and said she would have found it "offensive" if anyone suggested it.
She said that the fact that Mr Mosley and witness B spoke German meant that "those of us who were submissive did not know what those who were dominant were going to do. This adds to the surprise factor and excitement".
She also denied that she was dependent financially on Mr Mosley.
She said: "I see lots of guys. I am dependent on the scene, but not on one particular person."
Earlier Mr Mosley said that at no time did he or witness A, who arranged "parties" like the one on 28 March, 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."
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 because he was acting out a Nazi scenario, 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.
The News of the World's editor, Colin Myler, told the court that based on the video and the conversations that the paper had had with E, he believed the story was one of "legitimate public interest".
He denied fabricating the Nazi aspect of the story.
