‘We get lots of newbies, and I think what's exciting for them is that there are so many possibilities here,' he says. ‘People who come here definitely seem to have a great sense of humour, and they're engaging and great characters.'
It's dark and inviting, and smells faintly of popcorn, a trick the club has implemented to conceal the natural smell of sex that'll soon fill the air.
As we descend the stairs, I spot a large bed with a TV above it, set to porn, and a large vibrator, free for all to use. An hour later I saw a woman give her partner a blowjob as she enjoyed the vibrator herself, so it definitely gets used.
‘The dungeon affords lots of excitement,' Master Boudoir explains, including a padded wall, a St. Sometimes, couples will say to me ‘Master Boudoir we've seen you do your thing, would you mind showing us your techniques'.
‘I've got my bag of tricks and I'm constantly adding to my implements, and it's always to increase the woman's pleasure. Each woman has different triggers and yearnings, so I'm very careful about asking what she'd like and I check whether she's OK at each point.'
Master Boudoir is teaching me and Cassandra how to spank a blonde lady who is restrained on a bench, while she gives her partner a blowjob.
Meanwhile in the two prison cells, one of which has a sex swing, two couples are having sex as the whole room watches
Feeling somewhat awkward and out of place, I promptly apologise when I spank her, to which I'm met with kind laughter by both the woman and her partner.
I sit down and take in the view: there are several couples having sex in front of me, while to my left there's a woman orgasming as her lover plays with her
It's all very voyueristic, and I can sense which couples have been here before. It's not a naked fest though – most of the crowd have their underwear on, while others are fully dressed still.
I leave Cassandra and the Master to do their thing, and venture outside to the smoking area, where I chat to a few of the guests.
It's a mixed bag, but it's a much younger crowd than I'd anticipated and most of them are fairly attractive.
Especially this one gentleman from Scotland, who has come along with his female friend – I catch both of them in a swingers situation later that evening.
Another couple tell me they came along the night before, and found a lady to play with. She had come on her own, and apparently she also ‘came three times'.
Overall, the crowd is friendly – the seedy element that I'd expected isn't present – but that's not to say there's not a lot of kinky sex, most of which takes place on the top floor.
Yes, there's definite f**king, but no one is in a rush, they're taking their time and they're enjoying having an audience.
I'm surprised by how quiet the room is; the music is playing in the background and women are moaning softly, but no one is screaming load enough for the neighbours to complain.
Whether this is the official way of doing things, I couldn't tell you, but I had three men extend their hand to me that evening as a gesture that I was welcome to join him and his partner.
