Whipping up business: Emma Sayles has seen booking rise thanks to Fifty Shades of Grey

A friend of the Duchess of Cambridge who runs sex parties for the rich and ­famous says business is ­booming – thanks to Fifty Shades of Grey .

Emma Sayle’s members-only elite sex club Killing Kittens has seen ­bookings for its bondage-style ­parties sell out in the run-up to the kinky film’s release on Friday.

The 36-year-old told the Sunday People : “We almost doubled our turnover in October when we launched Torture Kittens (a bondage spin-off) and it’s all because of the Fifty Shades of Grey effect.

“An event in October almost sold out overnight and the girls-only book club events, in which we hold talks about how to be a dominatrix, got much busier.

“They’re similar to the regular parties but have that edge to them and all the rules are the same, with women as the main aggressor.”

Diplomat’s daughter Emma, who founded Killing Kittens in 2005, said: “It’s a safe ­environment to act out sexual fantasies you’ve always wanted to take part in.”

She said Fifty Shades – in which Dakota Johnson and Jamie Dornan play a student and domineering businessman having an erotic affair – had given women new confidence to explore their sexuality.

Emma explained: “If you’d told me ten years ago that I would be expanding to bondage-style parties, I would never have believed you.

“I’m finding that my regulars who’ve always attended the parties feel they aren’t getting enough, which is why I’ve introduced Torture Kittens.

“Girls who were sort of on the fence about wanting to explore are now taking the plunge and actually coming to the regular parties.

“It’s always bugged me that men can go out and do what they want but the minute a woman does it, she’s considered a slag.”

Emma – who met Duchess of Cambridge Kate on a charity rowing team she set up in 2006 – now has around 50,000 members, with up to 200 people ­attending a party.

Tickets cost around £120 for a couple or £50 for a single female.

Parties are normally held in stately homes and penthouses across the UK with regular events also in Manchester and London.

Female guests show up wearing smart cocktail dresses but as the evening goes on and the alcohol flows, they begin slipping away.

Emma is planning to launch in New York and has agreed to sell bondage-style sex toys and lingerie through the Ann Summers shop.

The first-time mum, who had son Rafferty in October, has just got engaged to Olympic hockey star James Tindall, 31.

He popped the question last Sunday while on a walk with Emma, their son and cocker spaniel Rex.

Emma said: “It was totally ­unexpected. We had spoken about it before but I never expected it. He took me to a park and said that he’d spoken to Rafferty and Rex and that he’d decided we needed to be a family.”

The couple now plan to tie the knot in October and Emma has already started planning the big day.

Emma’s time is now spent in meetings and organising events – with her baby son in tow.

She said: “Some girls grow up thinking of nothing but getting married and having babies.

“But I’ve always been focused on working and sport so it kind of crept up on me and Rafferty’s now come into this world I’ve created.

“One minute I’m ordering a box of condoms for a party, the next minute it is time for a feed or a nappy change.

"I’ve learned babies will sleep anywhere so within weeks of having him I’d hop on a train and have meetings near Waterloo station.”

But Emma, who has never taken part in the orgies herself, said she draws the line at dragging her son along to the parties.

She said: “I’ve been able to take a step back from attending the ­parties since having the baby.

“Thankfully I’ve got a good team who can do that for me and now my evenings are spent making sure I’m in bed by ten.”

She added with a laugh: “But I still get all the dirty details the ­following day.”
