Even from a stupid porn scenario, it only makes sense that Irys is the one that breaks Bae in every hole with her enormous futa cock until Bae's ability to speak, see, breathe, or even think is completely shattered. From all of their interactions, it's clear as day that Irys is the dominant of the two.
