When a submissive sees the raw animal desire being focused from her dominant and he consensually marks her as "his".
Her stomach will feel butterflies, her body should go warm, there should be a tingle from that special place up the spine to the base of the head that gives her a braingasm.
Then she will become engorged and wet and then the dominant will mark her again ... and again ... and again.
Until she breaks, because she will.
There is nothing sexier then watching the female warrior in the woman throw down her sword and say fuck this I can't win.
To see the glass girl inside quiver saying no daddy/master, please no more ....
Little girl/my love ... I am going to mark your soul as mine and that means burning every wall in you down again and again and again.
