also you should give the girls a domination phase when you submit to them
having each with their own desires they could each have their own reactions to a submition over loss
i love the primal girl so ill use the weaken prey idea here but when you submit instead of weakened prey maybe she walks over you and sits down then starts to wildly lick your neck as she takes her prize that gave up
she slowly builds up untill she pulls away and you see her in her primal form your prey to her and now shes gonna use you the way she wants to
if you submit to her she would give you so many debuffs and buffs it would be like incys confused you could even give him a limp and stagger to show she fucked him hard both mentally and body wise [failing to remember how to spell something is nice it makes you adapt :) ]
