David/Torgal (pregame, probably?), the D/s they enjoy in private, and how that's kept separate from their public roles -- I could see this being really interesting with either of them topping, so please do it whichever way appeals to you (or explore the dynamics they'd have switching, yum). I have a super weakness for David picking up sovani ferocity/mores from Torgal's influence, so if that appeals at all I'd love to see that explored, whether that means demonstrations of self-control or animal dominance displays or any other manifestation that works for you.
