kime blaster01 :dom, is just seeing what is comfortably accepted. Why would you not keep pushing, so long as the sub keeps making it clear it is ok. Thing is, subs like her, tend to implode into whatever and then define that as what they are obligated to accept in their own minds.
Yeah, this is far more about the sub's nature than the dom's. The dom may be taking pleasure in pushing the sub, but the sub, well, she seems to just collapse into every new pressure. She does not ask, let alone demand respect. There is a long series of these videos, where I get the sense that the dom, just keeps getting more comfortable, and the sub, just keeps emotionally collapsing further into her subservience. Don't think the dom is particularly nasty, just the sub has gone a long ways in terms of erasing any resistance in herself.
