Well it's moot whether or not she'd be ok with it because nobody asked her before doing it. Either way, it is a betrayal. The real question is, will she be mad about it, and if she is, will she be able to forgive.
In that sense, Roxxy's route handles sharing better, she does it on her own terms, she sets clear rules and she needs to be present when it happens. There's no guilt there, nobody's going behind anyone else's back.
Again, being porn it's expected you'd get with more than just he one woman but, as much as I love Odette, she does go too far sometimes. Just my opinion.
