Interesting. I see what you're saying and I agree.
If a slave endures pain for her Master it is a type of devotion to him. As long as it's SSC, I can see how this could be very erotic for the right two people.
For me, it probably wouldn't work. I don't believe I'd want to endure pain for my Master's pleasure. I'd rather try to find some other way to give him pleasure. I like some kinds of pain, but I think there would have to be a mututal agreement in place for this to work. Dependent upon the bond between a Master and slave this arrangement is entirely possible. I think for me it would be a limit though, but one I would allow to be pushed gradually.
