This is surprisingly common among D-types, and actually mostly takes a little practice to find your entry into it.
First of all: What you say matters much less than how you say it. I have been spouting nonsense, trivia, lecturing popscience with great effect.
How you say it will have to be tailored to you. Use mannerisms, modes and phrases as you please, it is partly conveying your dominance that you choose (power of agency), and also the simplest way to keep communicating clearly.
Also, you'll want to find how the words complement your actions. I'm thinking that you're used to using words in tandem with your other implements, and just need to broaden your repertoire. Start easy: use one thing less, introduce one new thing, or do it with grabbing/slapping/spanking interweaved between your comfortable combos.
For me, dominance is about keeping the initiative, supporting submissive behaviors, and rewarding good behaviour. One favorite game is thus to create a setting where it's easy for my sub to service, like with some posture training, certain rope play, showing off, etc. I then make sure to keep them off balance enough that I still get to call the shots. "Arms higher, eyes down, chest out and breathe deeply for me, let me see that body move, dance, for me. What a lovely little body, and capable of so much pleasure as well. Arms higher! Don't make me correct you again, it will be far less pleasant...", and of course when they behave they get "good pet", strokes and orgasms as appropriate.
As they surrender/space, they won't be paying much attention to the actual words, and I can modulate my voice to say almost anything, and then just change it when I want them to pay attention.
This is loads of fun with brats, they often come up with rebellious ideas, and when talking like it's easy to have them lose track, and eventually agree to the opposite of their point, or for even more fun, to agree that I pervert it into something they didn't actually want. "Oh you want to escape from the ropes now? wWell, you should really have said so earlier, so that I could plan a proper rope session safe enough for you to struggle in, now I have to do all this extra work to make sure nothing risks slipping in a dangerous way, taking me out of my flow, and also not giving me a proper chance to RACK the session. I think the only way we're going to have this work is if I get to watch very closely, so that I can interrupt if something dangerous happens. Now, how would we go about making sure you notice me while you're struggling? I'm thinking we're gonna need something that makes a noise, and physical sensation enough for you to notice, don't you agree? Good thing I have this cane handy here, I'll also need to make sure nothing is too tight or has restricted blood flow, so I'll also be poking you with the cane from time to time to make sure. And as I'm going through all this trouble for you, you'll have to do something for me as well, that's only fair no? How about you show me some appreciation for all this extra work, how about you continuously praise me for being such a generous, caring and nice dom? At least until you've broken free."
In that barrage of semiplausible phrases, you can easily substitute any activity (maybe you get to spit in their mouth to gauge if they're still OK? Or get to tickle them? Or use a rolled up newspaper? Or have appreciation breaks with praise and/or oral pleasure?)
There are countless ways to communicate, so what works for you may differ, and that is as should be.
Erotic fantasy is what it is, we get ideas that evolve and become intense sources of pleasure. Some fantasies are inherently hotter in theory, some are unfeasible/impractical to realise, and some could be fun to try in a safe and consensual setting. Some you'll want to keep, some let go of, and most you'll continously re-evaluate as you and the ideas continue evolving.
(The Erotic Mind by Jack Morin is a fantastic read on the topic)
Having fantasies is entirely normal, including of "extreme" situations, it is part of how we deal with stuff and how we explore what brings us pleasure and release. They're typically not problematic until they keep you from living your best life (like if they get intrusive or compulsory), or if they cause you harm to think about or realise.
Besides, there are many things to find hot in such a scenario: being the vessel for someone's pleasure, releasing your self image, relinquishing/surrendering control, breaking taboo/norms that keep you from pleasure, feeling vulnerable, feelling prized/conquered, as well as simply the prolonged agony in teetering between ecstasy and pain before exploding in intense pleasure.
I find many of those hot with the right partner, and in my experience variations of these aren't at all uncommon.
There is however one thing to keep on watch for, self harm through risky behaviour. Good kinky fun is great and healthy, as long as you go into it with consent (including a way to revoke it at any time), some idea of boundaries/limits and a respectful discussion with your potential partners to make sure you all understand, trust and can manage unexpected situations together.
This is mostly only necessary for realising the fantasy though, in your mind's theatre you can go as wild as you please. Regardless, I wish you many orgasms and more pleasure!
