Im as kink friendly as it gets. But scat is off the menu, period.
There's plenty of stuff that I don't or won't participate in as a receiver, like sounding as an example, but it doesn't bother me at all to see. But if there's scat play going on, I'm out. Don't want to even see it, much less smell it or hear it.
My own kinks run towards bdsm. Predominantly dominance play, bondage, and pain. I'm dominant, and being tied up isn't interesting to me, but I enjoy pain for myself, though not all types in all situations.
My preference is for gentle domination rather than aggressive or demeaning, though I can do that. I just really enjoy the process of taking a partner deeper into the sensation of giving up control, sinking into the pleasure of pain. To me, the most fun way of getting there is slow, gradual, and in a way that's more a seduction into the darkness than a push. Even using floggers and whips, I like to build up, layer sensations and types of pain until the sub gets pulled under by their own mind rather than being overwhelmed from the outside.
If that's done while the sub is tied up, be it as simple as wrist cuffs, or as complex as a suspension, all the better. I like them knowing they could be free, if they asked for it, and getting right to the edge where they might safe word out, but don't want to because there's still more to experience.
But, when I'm in the mood to receive sensation, take pain, part of my enjoyment is in not needing the restraint. It's pushing myself to my own boundaries that does it for me. I want something I can grab to keep myself stable, but that I can't rely on keeping me upright. If I fall, I want to fall, not just hang there, if that makes sense.
I prefer to top women, but have topped men as well. It's less sexual with men, since I'm not attracted to them, but when the sub needs some degree of sexual activity, I can manage to do it. I can usually rely on the dominance play to give enough arousal to give them what they need, if they do need it to be sexual. A few times, back in my younger days when I was still active in the local scene, I needed a woman partner involved if a man wanted some kind of sexual interaction as part of the scene, and I definitely performed better with a woman involved.
To me, there wasn't much difference in my own enjoyment between topping a man my way, and topping a woman that preferred very hard methods, or wanted a fast ramp up in force. Sure, I didn't and don't enjoy men, and I do enjoy women, but my preference for my style of dominance and pain is more enjoyable than other ways of doing things. It's one of those "at least I'm playing at all" kind of things.
And I definitely enjoy pleasing someone that's a long term partner any way they need. But when you're playing with people at a party or small gathering, it isn't always going to be your actual partner, and it's still fun to play when single, so applying sometimes you work outside your preferences
Me and my wife play together, but we stay monogamous unless it's a very special occasion.
One part body language, one part voice control, and one part words
A lot of dominance is about how you approach a person, right? You tie them up, bend them over, whatever, but it's about establishing position. So when you can't touch or do that, you use your body. Get closer to them, inside their space. Loom over them, even if you happen to be shorter. By owning their space, you control their mind at least a little.
Then, you use your voice. Going deeper is helpful. A growled threat is often more effective than a slap, and it's almost always better than your normal voice. Volume matters, but not louder. You're in close already, so put some menace into your voice, lean in a little closer, and drop the volume. A little audible sneer may go well for a brat too.
When choosing words, I tend to like starting with questions, especially when someone is playing brat. You lure the brat out, ask them if they know what's going to happen if they don't obey. As soon as they start to answer, interrupt and tell them only to answer when told to. Ask again, let the brat start to surface and interrupt with a sharp sound, like slapping your own leg, or a table, then tell them you didn't say they could talk.
Some brats escalate, others are going to be shaken out of it since most brat play is about the acting out and eventual punishment. So, when you change the script, it flips a different switch in their head, it breaks out of the expected. When you do that, it doesn't matter if they escalate, because you double down on the quiet and forceful side or things. If it breaks them into being a good little girl the first few times, that's great too; nothing wrong with an easy move into their headspace.
You can, with a bit of luck and some practice, get some subs all the way into their subspace with no touches at all, if you keep ramping up the pressure by using your presence and voice.
It helps if you imagine them tied up or on their knees as well. Getting into the right metal space makes the performance easier because it stops being a performance, you become menacing and in control.
I can't promise it'll work, as obviously everyone is different, and your little brat may need a different scene. But it usually does work when doing something physical isn't possible.
