The usual infrakinky m/f thing is that the guy is taller and stronger, and therefore the girl is that much more helpless. For some d/s couples where that’s true, it must work out nicely. He doesn’t need much effort to keep her in line.
I enjoy contrasts like this. She is so much more naked because he is clothed. The belt in his hand speaks of wonderful needs getting met for both of them.
