Transactionalism in my D/s world

In my flavour of D/s (which really is who/what I am, not some kind of role or play I put on for an hour), I intrinsically prefer what I am hereby naming transactionalism. I'm aware this word already has its definition in philosophy but I don't really want to study philosophy to see if my definition agrees with what they have stipulated.

So what do I mean by transactionalism here? Imagine a situation where Sub, for example, expresses her wish to cuddle despite me being busy (as I often am). Then I don't want to just say yes because she wants it and I'd of course also enjoy it. I want her to have to do something to please me. Something to show me that she is willing to walk the extra mile for me. So my intrinsic response to her request, almost at a reflex level would be: Yes, but only if you are a good girl and put on your catsuit. Now of course it doesn't always have to be a catsuit, but something else that we both know that I will enjoy a lot.

Another example situation could be: Sub wants me to accompany her to some place/event, like shopping or a meeting with friends or whatever. To clarify the situation let's assume it's some kind of event that I probably wouldn't have chosen to go to myself. Let's say a Museum that's not not within my area of interest. Then I don't want to say "yes" just because I love her, or because I want to be there for her. I want to do it because she does something for me. So my response could be Yes, but only if you're a good girl and wear a properly laced corset under your sufficiently short dress with pantyhose underneath. It could of course also be something else, like Yes, but only if you are a good girl and wear a remote controlled vibrating toy in your pussy or Yes, but only if you earn it by giving me a blowjob before and afterwards (or in a break during the event, or whatever).

And one can of course play with the above: Whatever sub has to do in order to get her wish fulfilled can of course depend on how much an ask it is. In the end, I would say I can be convinced to do virtually anything, if only whatever the "bribe" she will do in return is high enough. Does that make me less dominant or less in control? I don't think so. It's still my decision to determine the task ("price"), and I can of course still say no.

After some time, it is fair to assume that for repeating, regular, common things, standard payment terms are established either explicitly or implicitly. For example, taking the above example (Sub wants me to cuddle while I'm busy with something else): She would know that I'd ask her to wear a catsuit and put that on even before asking to cuddle. That's basically then more or less the same as if we had established a formal rule (rules are common in D/s, after all). She could then dress accordingly, come to me, do a little show off her body/outfit and basically seduce me to cuddle. And if she wants to be super sure I'll go along no matter how important I think my current task is, she might add something else, like platform heels, a corset, a ball gag or whatever she knows will certainly push my buttons.

I really do love that kind of transactional dynamics. And I do like to use this mechanism to get her to do (or wear, endure) more and more of what I want. So absolute pricing is potentially going to increase over time, but at the same time, ideally, she should be more used to the things I ask of her, so the amount of discomfort/effort/difficulty should be getting lower.

All of I also the above doesn't mean I don't like her. I just want to see that she will go the extra mile to please me. Also, it offers her as a submissive a chance to get virtually anything she wants - just as long as it is important enough for her to pay the price.

In my experience it is very important what Sub feels when confronted with this. Does she like the challenge of the things I ask her to do? Does she love the feeling of giving me what I need? Does it make her happy to know that she is fulfilling my deepest desires? Does she enjoy being a good girl, no matter how I may define that? Is she proud of being able to do what I ask of her? Then this kind of dynamic can work well. But if she only looks at it as a chore, and it's just painful / annoying without some level of satisfaction, gratification, arousal or other form of enjoyment, then it's likely not going to work out.
