I really love affectionate muscular, rough-loving futa's, and there has been a tonne of great mentions already. I don't particular care for or worry about the concept of dom/sub dynamics, beyond the actual acts themselves often associated with it, but I greatly enjoy a "dom" amazonian futa being affectionately rough, day long, with an incredibly eager "sub" of a woman. I don't know why physical acts like manhandling, groping, mating press, full nelson, prone bone, and chokeholds are so enticing in fantasy, but they definitely click with me.
I've grown to further like Arona and her content, especially when it's fleshed out with nice touches like her having a variety of pet/kink names when you approach her, but also calling you her "favourite sparring buddy" and that interesting dynamic where-in she respects you as a leader and warrior, but also absolutely adores you as a sub. Her basic scenes are perhaps a bit dry/short comparatively, but she is getting enough extra content and flavour where it's just fun to have her around.
I also like her insights on the world as a companion and her spark of cunning/wit. I like lore and world building, and I worry about missing out on it if I don't bring certain companions, so I like that she still is able to provide interesting facts and insight, and isn't relegated to her trope.
