Aranea shows up randomly to help during a fight, ends up getting in Ignis' way. Ignis corners her and gives her a telling off... which turns her on.

Maybe she breaks this yelling off by guiding Ignis' hand into her panties? Either way, as soon as Ignis feels how incredibly wet she is, there's no way he can resist. All this time on the road with no outlet? He can't wait to slip into her.

I'd love Iggy to be in charge, and totally into getting messy. I bet he eats pussy like a champ. <3
