Breasts. Both personal preference and also just the fact that its something that marks her as more "gifted", more "womanly" and all that in addition to her being a fucking monster that can just destroy anything with the insides of her mouth and stomach, but also because of tying into breast envy, lactation, paizuri, and just breasts seeming more explicitly sexual than asses in general
Plus boobs have a specific purpose of feeding and it's easy to imagine having larger ones implies more milk storage/production by porn physiology
Imagine a pred gf teasing you with how many people she's gulped down and brutally digested just to get her titties and asscheeks to their current size...
