Koulla Kakoulli (Greek: Κούλα Κακουλλή; September 1961 – 2 or 3 August 2018) was a British musician, professional dominatrix, and competitive bodybuilder. Born in Forest Hill, London, and later based in Brighton, she worked under the scene name Mistress Dometria and ran the Brighton Dungeon, a dedicated BDSM venue. Her life braided rock-scene family ties, late-life physique competition, motherhood, and pro-domme craft until her death at fifty-six.
Music and Family
As a musician she sang and played keyboards and guitar. She backed The Only Ones and fronted her own band Lonesome No More. Her sister Zena Kakoulli married Peter Perrett and managed both bands; her brother Harri Kakoulli later played bass for Squeeze. That network placed her inside British alternative music circles long before dungeon ownership defined her public image.
Bodybuilding and Dominatrix Work
In the gym she competed in the IBFA Ms. Universe Over 50 division—fourth in 2017, third in 2018—bringing a visibly powerful physique to the same years she was known as Mistress Dometria. The Brighton Dungeon was her professional base as a dominatrix. Filmmaker Stephanie De Palma made the feature-length documentary The Boss Lady about her work, giving screen time to a working English pro-domme and venue owner rather than only fantasy stereotypes.
Personal Life and Death
In private life she was a mother of five with four grandchildren. At the time of her death she was mourning the father of three of her children. She was found dead in the Brighton Dungeon on 3 August 2018. Toxicology found traces of multiple drugs; the inquest returned an open verdict. The coroner offered a rare personal eulogy from the bench: of many people met, Koulla was “one of the most amazing,” living as she chose, “extraordinarily well organised,” with a huge number of people who loved her.
For British BDSM history she stands as a multi-hyphenate: session dominant, dungeon proprietor, documentary subject, musician with punk-adjacent pedigree, and late-blooming bodybuilding competitor—proof that a pro-domme career can sit inside a full, complicated life rather than erase it.
