If you can comprehend the appeal of sizefaggotry, then you just gotta understand it's not about the brap itself, but part of the power imbalance appeal. She can so easily and utterly overpower you, completely overwhelm every sense of yours with just a brap, practically an autonomous, mindless function of the body. Just an absentminded, tiny thing that she does when she thinks nobody is looking, yet she totally dominates you with it.
Similar appeal to unaware stuff. You are so beneath the giantess that she doesn't even notice you, and every step of hers is a dangerous threat. Like her mere presence is a dominating thing.
