How would you word a request then?
Good question.
First, I won't assume that every service I like is available, just depending on the price.
If she has a tip menu, I stick with that for a while. I consider it rude to introduce myself by asking for something completely off her tip menu, though I know one user who apparently has exactly that fetish: Scan the tip menu and then ask something clearly beyond it. Pity I never saw him actually tip for an action.
That's the second rule: Anything I ask should be reasonably related to the tip menu. If there is no nudity at all in the tip menu, I would not ask for a full strip dance.
Now let's assume I stayed in the room for a while and I tipped a few times, and my preferred actions are not too far from the actions she offers. There are several ways to convey my wish:
Most easy is If she likes to talk to me in PM and she asks me what I would like to see. I can tell her what I like. Then she can offer the action or not.
If she keeps the conversation in public, I can sill talk about my wish, for example: “I would love to see these straps fall down”.
Then she can ignore the wish or perform it or offer it for an amount of tokens.
Some models using a smart app will use an app command to add a new option, thus I'll see something like:
Tip for Tasks: april_pretty added special action
37 ➜ Drop one Strap
If she wants to raise the bar, she can add it to her fan club menu, thus I have to become fan before I can tip the action:
Fan Club Only: april_pretty added special action 🗝 23 ➜ Drop one Strap
In any case, I don't want to make her explicitly deny a wish in public. If we talk about her actions at all, we should talk about the actions she offers and her beautiful performance, not about her denying the wishes of visitors. I try to improve the mood in the channel, not damage it.
