I'm Mistress Valkress (some know me as Mistress Gemma) and I'm a TS Pro-Domme living near Sheffield (United Kingdom).  I have over 20 years real life scene experience in the BDSM scene so you would be hard pushed to find safer hands to be in than mine! I studied BDSM at an academic level for 2 1/2 years before becoming a Pro-Domme and I have degrees in Human Psychology & Human Biology, so I really can 'get inside your head space' to give you the experience of a lifetime! 

"I guess some of my clients see me to be more of a councillor to them rather than a nasty dominatrix!"

I have also been House Domme at a London based nightclub although I no longer do this by my own choice.

"The club's just not the same since you left Mistress Valkress. Love, Roberta"

I also promote Human Pony Play in the UK as well as campaigning for better disability awareness in the UK scene!

"Disability Awareness extends to ALL walks of life... Not just the Vanilla!"

I both practice and promote S.S.C & R.A.C.K.

I share Chambers with my partner (Mistress Giovana) in our luxurious and very discrete private premises about 10 mins from the M1/JCN 31.  We have off-street screened parking for clients and our playroom is en suite so you can shower and freshen up after your session.

After so long in the scene I am proficient in the majority of scenarios:

  • Anal / Strap-on Play
  • Body Worship
  • Bondage
  • Boot, Shoe and Foot Worship
  • Chastity Control
  • Cock and Ball Torture (CBT)
  • Corporal Punishment (Heavy)
  • Corporal Punishment (Mild)
  • Corsets and Lingerie
  • Double Domme
  • Electrics
  • Face Slapping
  • Feminisation/Force Fem
  • Forced Bi
  • Gags & Hoods
  • Humiliation
  • Interrogations
  • Latex, Rubber and PVC
  • Maid / Sissy Training
  • Mummification
  • Nipple Tease
  • Puppy / Pony Training
  • Roleplay Fantasies
  • Sensory Deprivation
  • Sensual Tie and Tease
  • Slave Training
  • Trampling
  • Wax Play
  • Whipping / Flogging

I am particularly experienced in the following skills:

Shibari (rope bondage), Electro-stim, Violet Wand, Adult school boy/girl, CP, CBT/VT, Human Pony/Pet Play, Device Bondage and I love using Sensory Deprivation.  I also adore having my ass, legs and feet worshipped especially when I'm wearing one of my many, many pairs of high heel shoes & boots!

Human Baby Play, Watersports or Scat, Breath Play, Needle Play or any Blood Sports.

I had the pleasure of serving Mistress Valkress when she was the House Mistress at Candygirls Club in Sunbury on Thames. I had travelled down from Glasgow specifically to attend the club and to meet Mistress with whom I had already been chatting with on a TG chat site. I stood before Mistress and presented her with the gift of a Tawse which I had brought with me, well I am a Scot so what else would you expect, before kneeling before her with head bowed and hands behind my back. I was instructed to stand and Mistress started off with a light session on the, appropriate for me, St Andrews Cross, before ordering me to prostrate myself over a spanking horse after which she proceeded to use a variety of floggers, tawses, canes, crops and electrics on my bare flesh resulting in such amazing sensations that I was just lost in my own space and so have no idea how long the play session lasted. For a variety of reasons, Mistress and I lost touch but now that we are back in touch, I look forward to the opportunity to serve Mistress Valkress once again. Peace, luv n lipgloss Heather xxx

I would like to call this woman "Goddess" but she forbids me to even though she is worthy of the title many times over! Truly incredible is all I can say! Seeing is believing!
