Dominatrix Lady Lucine Diaz, Zurich: BDSM, Power, and the Psychological Thrill

Dominatrix Lady Lucine Diaz can bring her slaves to their knees with her presence alone. She is young, strikingly attractive, and knows exactly what she wants. The experienced and versatile Mistress from Zurich gives us an insight into her world — a conversation about the appeal of BDSM, power, and the psychological thrill.

This interview is part of a series of interviews with dominatrixes from around the world. New to Femdom? Our Femdom Guide provides a clear and consensual introduction to female dominance.

Lady Sas: Dear Lucine, please tell us how you found your way into the BDSM world.

Lady Lucine Diaz: SM and the fantasies associated with it have been part of my life for as long as I can remember, even before I knew what any of it actually was. As I got older, I became increasingly interested in it and began exploring and experimenting with different things.

However, my inclinations and ideas could never really be combined or fulfilled in my private life over the long term. That gave me the idea of finding another way to live them out — and ultimately combining work with pleasure.

Lady Sas: Have you ever explored the submissive side yourself?

Lady Lucine Diaz: Yes! It was a long time ago, but when I first came into contact with SM, I naturally experimented a little with both sides. From the beginning, though, I preferred being dominant.

Lady Sas: What is it about BDSM that appeals to you?

Lady Lucine Diaz: It is a game between power and powerlessness, between letting go and being caught. To a certain extent, you also get to know yourself better through it.

I find the sheer range of human erotic imagination fascinating. It never gets boring. I am dominant and have a healthy sadistic streak, so it is even better when that complements the person opposite me and we can enrich each other’s experience.

It gives me a huge thrill when I know that a slave will do everything I demand of him. I also enjoy taking things out on a slave sometimes when I feel like it or when something has annoyed me during the day. Without that kind of outlet, something would be missing from my everyday life. Other people deal with stress through sports; BDSM is my choice. [laughs]

Lady Lucine Diaz on Her Life as a Dominatrix

Lady Sas: Why did you choose the name “Lucine Diaz”? Is there a philosophy or story behind it?

Lady Lucine Diaz: I searched for a long time. One thing was certain: I wanted both a first and a last name. I noticed that quite a few Dominatrices had very similar names, or even exactly the same ones, and I definitely wanted to avoid that. I also did not want a name that was impossible to pronounce.

I went through names of deities from Greek mythology, Celtic mythology, the Aztecs, Egyptians, and so on, but nothing really appealed to me.

Then I came across “Lucine,” which means “moon.” I liked the name immediately. It sounded elegant and simple, yet sophisticated. I also felt that its meaning suited me. The moon is surrounded by myths, it is worthy of worship, it rules the tides — and even the sleepwalking of some people — and it shines in the darkness, which in a way is also associated with SM.

“Diaz” completed the name. To me, it has something elevated and noble about it. People often mistakenly assume that I have Spanish roots anyway, especially in summer when my skin is darker, so the name seemed fitting.

Lady Sas: Did you have a Plan B in case being a Dominatrix did not work out?

Lady Lucine Diaz: I never thought, “I am going to become a Dominatrix now.” It developed more or less alongside everything else, so in that sense, failure was never really possible.

I knew that I wanted to express this part of my personality in some form. After trying and exhausting other possibilities, I eventually decided to explore it professionally. And successfully — I am very happy about that.

What Is Looning, the Balloon Fetish?

Lady Sas: You also offer looning, the balloon fetish. What exactly does that involve?

Lady Lucine Diaz: This fetish involves inflating balloons, sometimes until they burst, and playing with them in different ways. For example, scratching them with fingernails, squeezing or poking them until they pop, or sitting on inflated balloons placed on the slave’s body.

That can hurt quite a bit when a balloon suddenly bursts. A major part of the fetish is the tension. You never know exactly when the balloon is going to pop. It gets bigger and bigger, and eventually there is that sudden bang.

There are also special balloons in all kinds of shapes, sizes, and colors, including balloons with holes in the middle. Often there is also a fascination with rubber itself, which is why the fetish combines well with latex outfits.

Lady Sas: Waterboarding is another practice you mention. How do you make sure nothing goes wrong?

Lady Lucine Diaz: This kind of play requires trust. Practices like these can also leave psychological marks if they are not handled responsibly.

If someone is restrained, gagged, or otherwise unable to communicate verbally, I give him an alarm button or an object to hold that he can drop as an alternative to a safeword.

Lady Sas: What is appealing about prostate massage from the Mistress’s perspective and from the submissive’s perspective?

Lady Lucine Diaz: First of all, it is an expression of trust when a “virgin” slave allows me access to that part of his body. I like that.

I like the sensation, the tightness, and the reactions I can produce in my slave through the massage. In a way, I literally have him “in my hands” and can “wrap him around my finger.”

From the slave’s perspective, prostate massage can of course be incredibly stimulating, although another person may experience it as humiliating.

Milking a slave through prostate massage can also simply be a practical way of making him release without orgasm, for example during prolonged chastity.

Lady Sas: Do you have any advice for women who are new to prostate massage?

Lady Lucine Diaz: The most important thing is a slave who is able to relax and who trusts his Mistress. The second most important thing is patience and plenty of lubricant. [smiles]

The rest is largely a matter of feel. In some men, the prostate is already quite prominent when they are not aroused; in others, it becomes more noticeable only shortly before or during climax. It differs from person to person.

Milking without orgasm does not work with every slave either.

Lady Sas: What makes being trained by two Mistresses particularly appealing to a slave?

Lady Lucine Diaz: Two Mistresses initially promise twice the fun, twice the action, but also twice the thrill. Being able to withstand two Mistresses is probably an intense fantasy for many slaves.

There is often even more uncertainty, especially if the slave does not know either Mistress yet: “What are they going to do to me?” “How hard will they be on me?” “Will I be able to endure everything?”

A session with two Mistresses does not necessarily have to be harder, but it certainly can be.

Of course, the two Mistresses need to get along. Not every Mistress works well with every other Mistress. Good teamwork is essential.

With a duo, an entirely different dynamic becomes possible. You can play off each other, develop completely different ideas together during the session, and create interesting role-play scenarios.

Someone who is aroused by verbal dominance or humiliation can also get much more out of it because instead of a monologue from one Dominatrix, there can be a dialogue between two Mistresses.

Lady Sas: You also practice chastity. What is the longest you have ever kept a slave chaste?

Lady Lucine Diaz: The longest was about three months.

Watersports: An Invigorating Sense of Power

Lady Sas: Describe what you feel when a slave receives your urine.

Lady Lucine Diaz: It gives me an invigorating sense of power when a slave is lying beneath me with his mouth open, perhaps restrained so that he is helpless and cannot move away, while he drinks my urine.

Sometimes I can see the fear in his eyes — whether he will choke, whether he will be able to drink everything, and whether he will manage not to waste a single drop, knowing that otherwise punishment may follow.

It is something intimate and special, and depending on how it is done, the humiliation of the slave can make it enjoyable as well.

I like the idea that the slave will do anything for his Mistress, gratefully accepting and worshipping even this part of her. And depending on how urgently I needed to go, it can of course also be incredibly relieving. [laughs]

Lady Sas: How do you come up with ideas for a session? What inspires you?

Lady Lucine Diaz: The preliminary conversation gives me the basic framework: the slave’s preferences, limits, and previous experience, particularly if I do not know him yet.

During that conversation, the first ideas often begin to form, and then I develop them further in my mind. Usually, I start mentally preparing for the slave several days before the session, unless it is a spontaneous appointment.

Because of my experience, I naturally have a certain repertoire of ideas that I have either already tried or still want to explore.

During the session, I always leave some room for spontaneity because I want to remain flexible depending on my slave’s reactions.

New ideas can also emerge during the conversation afterward or when I read a session report, including ways to improve or vary certain elements. That exchange can be extremely valuable.

Some slaves write an entire “script.” I am happy to play through something like that, although I always reserve the right to add some of my own ideas.

Stories and video clips can also be very inspiring.

Lady Sas: Are there things about your work that annoy you?

Lady Lucine Diaz: Yes. For example, when slaves waste my time through unreliability or unnecessary questions.

I designed my website to be clear and, in my opinion, interesting to read. I expect a slave to think about his own wishes and ideas beforehand and to inform himself about both the Mistress and what she offers.

I am happy to answer genuine questions, but sometimes it is obvious that someone has not read a single line of information that is already available. That is frustrating.

It also bothers me when slaves fail to signal that something is wrong, that a boundary is being crossed, or that there is another problem, despite my instructions to communicate these things — and then complain afterward.

It matters a great deal to me that both of us enjoy the experience. I find it disappointing when a session leaves both people with an uncomfortable feeling simply because someone stayed silent at the wrong moment.

A session can energize me and make my entire day better, but it can also bring me down.

Lady Sas: What are your plans for the future?

Lady Lucine Diaz: I am very curious about medical play, and I may pursue further training in that specialized field.

Over the next few years, I would also like to travel around a little, work as a guest Dominatrix in different studios, and perhaps meet other Mistresses so that I can expand my experience.

Lady Sas: Thank you for your time, Lucine.
