Our Pink Slut Factory: The Last Sissy Heaven Soirée

Posted on 20/07/2026 by Mistress Sidonia

I attended Lady Sara Borgia’s last Sissy Heaven Soirée – and thought you’d like to hear exactly what we all got up to…

Our Pink Slut Factory: The Last Sissy Heaven Soirée
My first Sissy Heaven party was every bit as deliciously depraved as expected, inside what I named – The Pink Slut Factory. Hosted by Lady Sara Borgia along with myself and Mistress Inka, the event turned a room full of desperate little sluts inside out.

The theme was pink and slutty (with one classic maid and a cheerleader thrown in for good measure). The sissies arrived to full makeup, wigs, and big fake tits, all locked into chastity cages and sculpted into proper toys. Inspection came next, with punishments for any failings, followed by a sexy catwalk and photoshoot.

(And well we needed to do something will all those pics from the photoshoot. So I made my own Magazine: Sissy Gooner Weekly! See top of page)

Then the real debauchery began: sissy games that got them up close and very personal with each other. A filthy live sex show erupted — sloppy cock sucking, ball worship, and plenty of cum snowballing between the brainless bimbos.

There were plenty more sissies in attendance, but having your photo taken at the party and/or shared on-line is completely optional.

Lady Sara and Mistress Inka watched and laughed as they transformed those simpering ex-males into eager, hardworking cock-sucking sluts. No humiliation was too low. The pee flowed freely all day. Afterwards came dinner and drinks out, then a return to the chambers for more goddess worship, facesitting, and whatever else the Mistresses felt like doing with their broken little pets. It was an absolutely fabulous afternoon and evening — a true sissy slutty ball.

How AI Is Hijacking Female Sexuality & Agency

Posted on 16/07/2026 by Mistress Sidonia

Prompt: Listen, Mistress… tonight you’re going to crawl, call me ‘Daddy’ and thank me for the privilege, and smile while you do it.

How AI Is Hijacking Female Sexuality & Agency

As a sex worker and feminist I’ve always believed in women’s agency over their bodies and sexuality. Yet recently, Instagram (and it’s starting to pop up on the cesspit – X), has left me deeply unsettled. The platform is now flooded with short AI-generated clips (usually just 3–5 seconds long) featuring hyper-realistic “women” in pseudo-sexual, kink related or sexually suggestive acts. Many viewers don’t even realise these are fake. This trend isn’t just creepy – it’s strongly misogynistic and risks undoing decades of feminist progress.

The Rising Slop of AI-Generated Pseudo-Sexual Content
I’ve spent years trying to build a presence on Instagram, posting nothing explicit — no nudity, no adult content, each time my account was deleted. (I’ve finally managed to keep one open, but only by using a normal name and sticking to safe, domestic, white-background photos.) I get it — Instagram positions itself as a mainstream, family-friendly platform for creativity and connection. So why is my feed flooded with ‘clickbait’ AI-generated women simulating pseudo blowjobs and sex acts in every other post?

It feels like Instagram’s moderation has shifted to AI systems that are either overly aggressive toward real creators and oblivious toward synthetic content that evades the algorithms. This is a huge problem for sex workers. Platforms like Instagram and X (Twitter) are essential for building visibility and connecting with clients. When legitimate creators are suppressed while fake content thrives, it creates an uneven and exploitative environment.

AI “Women” from the Male Lens
Scrolling Instagram today, it’s overwhelming. Almost every other post shows AI-generated deep-fake women in disturbingly realistic clips: grinding/suggestive movements, simulating blowjobs or sex, public humiliation, implied watersports, upskirting or other demeaning and non-consensual acts — all careful just to ‘imply’ the action while fully dressed in street clothes to dodge the content filters.

As someone in the sex industry, I have zero issue with consensual adult acts – including BDSM, submission, humiliation, or rough play – when women choose them freely. The difference with AI content is stark: there is no woman. These images are created entirely through the male gaze, with no filter, no boundaries and no agency. Created for fast clicks. Men can make the AI ‘women’ do literally anything. This takes us backwards.

Eroding Women’s Control & Decades of Progress
In the 1950s–80s porn was often deeply misogynistic, crude and exploitative because it was made almost exclusively by and for men. When women entered the industry controlling their own content, we gained control. Performers could say “no” to certain acts, demand better conditions, and actively shape content that better reflected female desire and boundaries. With fairer recompense for our work came real economic power. The result was more balanced, positive, and authentic erotic imagery — even when it remained explicit or submissive. AI threatens to erase that progress. It hands total control back to the male lens, removing women’s voices entirely!

Real-World Harms
Many of these clips depict scenarios that would be illegal or platform-banned if real: non-consensual acts, public BDSM, or scenarios involving what appear to be ‘very young’ looking women. Yet they slip through because they’re synthetic and cleverly disguised. Worse, these clips often link to scam sites promising “real” interactions. Click through and you’re unlikely to reach an actual woman – or even a real person! Another concern is whether these AI faces and bodies are created from stolen images of ‘actual’ women. While I don’t have definitive proof, the realism suggests massive datasets scraped from the internet, I’m sure without consent. That raises serious ethical and legal questions about digital likeness rights and exploitation. Would you like your ‘image’ used to perform acts that are demeaning or illegal?

AI Is Just a Tool – But Tools Have Consequences
AI itself isn’t evil. Like any powerful technology, it brings both incredible positives and serious risks. In creative fields, medicine and education it can do wonders. In sexual content, however, it currently amplifies the worst impulses: removing consent, agency, and accountability. We need better platform responsibility. Instagram must improve detection of AI-generated sexual content, especially when it mimics non-consensual, misogynist or underage-adjacent scenarios. Creators deserve clearer rules, and users need transparency about synthetic media.

Exploitation 2.0

This trend gives me grave concerns for BDSM clip stores and fan sites like OnlyFans. It’s not just that we risk losing our customer base to cheaper, endlessly customisable AI alternatives. As women, we could end up losing all our agency, dignity and control – reduced to competing against perfect, compliant digital fantasies that never say no, never negotiate boundaries and never demand respect or payment.

The feminist and women’s movements fought hard for decades so that women could reclaim control over our sexuality and how we’re portrayed. AI-generated “women” who exist only to fulfil male fantasies – without limits, refusal, or humanity – threaten to roll back those gains. Sex workers, women and male allies alike must unite and push back. Demand that AI-generated content be clearly identified as such – or, where appropriate, limited to real people who retain full control over how their image and likeness are used. Demand better moderation. Support ethical content creation. And stay vigilant about how technology shapes – and distorts our bodies and our sexual culture.

For full transparency: I created the header image for this article myself, and I wrote every word (though I did run it through a spell-checker and grammar tool). This is really me — Mistress Sidonia. I write 99% of the articles on this blog personally. I’m a real woman, a real world dominatrix and these are my genuine thoughts and experiences.

Who Was the World’s First Dominatrix? Pt2

Who Was the World’s First Dominatrix? Pt2
Read Pt1 here

Theresa Berkley –The First Lady Of ProDomination

The most famous of these female flagellants (and one of the earliest, she pre-dates the Victorian period) was Theresa Berkley, born circa 1750. She ran a high-class flagellation brothel, the ‘White House’ at 28 Charlotte Street (now Hallam Street) Marylebone, London from around 1787 until 1836. She was described as an expert with all implements of torture and her talents became highly sought after by the aristocracy of the day.

All the following quotes are further extracts from the ‘Flagellation’ entry in Ashbee’s Index of Forbidden Books, which I think place Miss Berkley as most certainly, the First Lady of professional domination.

“Her instruments of torture were more numerous than those of any other governess. Her supply of birch was extensive, and kept in water, so that it was always green and pliant: she had shafts with a dozen whip thongs on each of them; a dozen different sizes of cat-o’-nine-tails, some with needle points worked into them; various kinds of thin bending canes; leather straps like coach traces; battledoors, made of thick sole-leather, with inch nails run through to docket, and currycomb tough hides rendered callous by many years flagellation. Holly brushes, furze brushes; a prickly evergreen, called butcher’s bush; and during the summer, a glass and China vases, filled with a constant supply of green nettles, with which she often restored the dead to life.”

“Thus, at her shop, whoever went with plenty of money, could be birched, whipped, fustigated, scourged, needle-pricked, half-hung, holly-brushed, furze-brushed, butcher-brushed, stinging-nettled, curry-combed, phlebotomized, and tortured till he had a belly full.”

“Mrs Berkley has also in her second floor, a hook and pulley attached to the ceiling, by which she could draw a man up by his hands. This operation is also represented in her memoirs.”

Possibly one of the first photos of a ‘dominatrix’ circa 1920-30 of Nativia Richard possibly taken by Studio Biederer/ Ostra in Paris. We have no images of Theresa Berkley.

The Berkley Horse

In 1828 she began using a custom-built flagellation frame which she referred to as a ‘chevalet’ although it subsequently became known as The Berkley Horse.

“A notorious machine was invented for Mrs Berkley to flog gentlemen upon, in the spring of 1828. It is capable of being opened to a considerable extent, so as to bring the body to any angle that might be desirable. There is a print in Mrs Berkley’s memoirs, representing a man upon it quite naked. A woman is sitting in a chair exactly under it, with her bosom, belly, and bush exposed, she is manualizing his embolon, [wanking his hard cock] whilst Mrs Berkley is birching his posteriors.”

“A woman is sitting in a chair exactly under it, with her bosom, belly, and bush exposed, she is manualizing his embolon,”

In one surviving letter, a customer hearing about the Berkley Horse proffered Theresa Berkley this pricing for her services, “a pound sterling for the first blood drawn, two pounds sterling if the blood runs down to my heels, three pounds sterling if my heels are bathed in blood, four pounds sterling if the blood reaches the floor, and five pounds sterling if you succeed in making me lose consciousness.”

Suppressed Memoirs & A Renounced Fortune

After her death in 1836, her memoirs, which had long been announced for publication, were held back by the executor of her will, Dr. Vance. And, sadly like so much erotica and sexual material from the period was destroyed. It was rumoured to contain compromising letters from certain members of the establishment, “from the highest aristocracy, both male and female, in the land.” Their contents were so outrageous that it was claimed they could have “threatened the very fabric of society.”

(left: Illustration by Aubrey Beardsley, circa 1890, the great Art Nouveau artist whose work embodied Decadence & Desire, and Victorian Morality Mocking, who sadly died at age 25.)

The Society of Arts at the Adelphi (now the Royal Society of Arts) took possession of the Horse in 1837, with a public exhibition promoted by radical publisher George Cannon. An illustration of the apparatus is reproduced in the original 1880s edition of Index of Forbidden Books, however, it is unclear what happened to the device.

She left her considerable estate to her brother who had been a missionary in Australia for over 30 years. When he learned the source from which the money had been derived, however, he renounced all claim and eventually the whole estate, valued at £100,000 (about 11 million pounds in today’s money) was handed over to the crown.

Who Was the World’s First Dominatrix? Pt1

Posted on 01/07/2026 by Mistress Sidonia

Who Was the World’s First Dominatrix? Pt1

So who was the world’s first Prodom – Professional Dominatrix? Let’s define that here as a woman who had perfected her art, had her own chamber with specialist equipment and a generous clientele. Well the word ‘dominatrix’ was not used in its modern sense until the 1960s, where it was 1st coined in erotic pulp fiction and B-movies which brought about its more mainstream use. However, if we put that aside the first documented, established domme, then called a ‘female flagellant’ was the infamous Theresa Berkley… but before we meet her, let’s first set the scene for how the role of today’s dominatrix came into being.

The Flagellation Brothels of Victorian London

The Victorian era (1830 – 1901) was one of strict and rigid morals, refined sensibilities and repressed sexuality. It was also a period obsessed with erotic corporal punishment evident from the flagellant pornography, erotic literature and documented accounts from the period. So it’s no surprise that a flourishing network of prostitutes offering flagellation to their clients existed, (prostitution was, interestingly, legal). According to Prof. Van Yelyr in The Whip & The Rod (1941), it seems that female flagellants “supported 20 splendid establishments’ in London and was known as ‘the English vice’ ”.

The English Vice – The ‘English’ Mansion
The ‘English’ in The English Mansion, the name of this website, is actually a wordplay on this notorious expression and not, in fact, declaring that all our dommes are English, we welcome and showcase dominatrices from all round the world 🙂

Le Vice Anglais

Having surveyed the number of whipping whorehouses in London, the Berlin psychiatrist Iwan Bloch (under the pseudonym Dr. Eugen Dühren) in 1909 concluded that, “England today is the classic land of sexual flagellation”. (His studies on sexuality went on to influence Sigmund Freud.)

The Making of Victorian Flagellants

This interest in algolagnia (deriving sexual pleasure and stimulation from physical pain) appears to be the result, in part at least, of experiences of flogging at public school. Ronald Pearsall in Night’s Black Angels – The Forms and Faces of Victorian Cruelty (1975) writes,

“The outcome of the public school predilection for flogging, was that in later life … there were considerable numbers of young men anxious and often desperate to recapture the lost sensations, and for them the flagellation brothels thrived.”

The Swishing Poet: Swinburne

The highly respected 19th century British poet Algernon Charles Swinburne (1837 -1909) was well-known to be totally obsessed by corporal punishment. This was a result of his experience at Eton College, a public school (public schools were actually independent private institutions) and a number of his poems make reference to flagellation including this verse,
