#i'm... tempted

Neither of them are opposed to the idea (they are not jealous by nature) but its one thing to like the idea in theory and another in practice. Aredhel can be… hard to win over. She is fiercely protective of Julian, and as much as she wants him to get rawed from behind while she gets to watch him fall apart from the front she recognizes that he has some kinks, and those specific kinks in the past (in my head canon) frequently put him in situations where people took advantage of him, and were neither kind nor considerate of his needs. 

So any potential three-way situation would have to begin with her getting a good hard read on whoever their possible third is to make sure they aren’t going to pull anything, and also sizing them up to make sure she can basically kick their ass if things get out of hand.
