I feel that this trope has rapey energy. the Omega sometimes fights and the Alpha just about force themselves onto them. Or if not that, the omega is "weak" with her lust to be penetrated. It's very animalistic. Very dog behavior. Wolf. They can smell the scents of the other a mile away. Keen hearing. Have possessive instinct. Will fight other alphas to the death if there is competition. Force themselves onto the omega they desire. And finally biting them to mark them as property, that no one else can touch.
It's an acquired dynamic. But some would agree that it makes for very hot story telling.
