Exactly she tries to arch her back sometimes as a natural istinct to escape the pain. When when she stop forcing the belt and she relax down crying and surrendering, thats when the real submission and lesson begins!! There is a deep mind work and conjunction that comes out of it. Isn't that sweet as well?!
First of i have to see she looks beautiful and feminine. She probably has been flirting around and that's why she gets punished. .! Even if she didn't she probably will. Some hard whipping makes her for sure a sweeter wife and will her being a more obedient insiside and outside the bedroom!! So there is always a good reason to whip your woman. I would let her suck after!
