Married slut is fucking around with some guy who has a higher status than me in the group. We are both cool with each other and I have made some brief sexual advances with her in front of him and they were both cool with it. The only problem is that I worry she will just use me to make him jealous and therefore see me as an orbiter. Should I only flirt when I am with her alone? She probably sees me as an alternate at best, and a potential orbiter at worst, if I fuck things up. How should I go about this?
