Inside Kate Middleton’s pal’s £15 MILLION sex parties… with mid-dinner romps & strangers ‘going at it within 5 minutes’

, Emma said the idea came to her as she was aware women were being "s**t shamed for even snogging a stranger".

She explained that "if you're not heterosexuals and having sex in the missionary position, then you're somehow weird".

A statement on the Killing Kittens website reads: “Our party rules and community values have been about increasing equity, allowing women to step out of restrictive gender roles and embrace their sexual empowerment, whether that is exploring their desires, taking control in sexual situations or feeling confident to ask for what they really want in the bedroom.”

Adult Playground

In the past, Emma has described her events as "a house party where the wheels come off."

Only women can make the first move once inside, as men take a back seat.

Emma often visits her own events to ensure members are having a good time and states each party is different - with some taking their time to explore, while others have their kits off as soon as they enter.

She said: "Some of them are slow burners, but at some, people are going at it within five minutes."

At cabaret nights, she said people often move away from the stage to romp as soon as the show is over, even if people are still eating dinner.

"Sometimes, you'll be eating dinner and look round and see a leg appear through the curtain!" she revealed.

The company hosts around three parties a month and have even made it global heading to Sydney, Berlin, Venice and New York.

The masked black-tie bash is for members only, making it tricky to know exactly what goes on behind closed doors.

But Lucy Roeber, editor of Erotic Review, recently went to her first orgy at the age of 48 and described what it was like.

She wrote in : “Arriving upstairs, I saw a couple deep in conversation on a red two-person sofa in the hallway. It was only as I got closer that I saw his hand moving under her dress.”

Inside some of the rooms were large double beds with up to ten naked people getting down and dirty while there was also a dominatrix room and a separate dungeon.

Safest she's ever felt in a London nightclub.

Describing the orgies, Lucy, who did not take part, added: “It seemed that once on the bed, you could turn to one side and join in, with the other people’s verbal or non-verbal consent.

“As the night progressed, the beds became so crowded with flesh you could no longer see the red sheets, just body parts moving, heaving pumping; punctuated by the sound of female whimpering and wailing. The sound made me think of the cultural impact porn has had on our sex lives.”

After Work

Emma, who has three children with her husband, former GB hockey player James Tindall, now lives in a quiet village in Surrey – and she certainly raised a few eyebrows on the school run.

Emma says her idea to create a sex club for women was born out of fury and isn't at all surprised by the success.

"The success hasn't surprised me at all. Half the world's population is female," she explained.

"I was so angry when I started it in my mid-twenties. I just wanted to p*** so many people off.' 

A school mum friend, newly single in her forties, joined Emma at an 800-person London event and claimed it was the "safest she's ever felt in a London nightclub".

"My children go to a little village primary school and I think that bomb [about her line of work] was dropped even before I joined. They love a gossip."

But the entrepreneur revealed she has won over the parents at the school gates now.
