Poll: Reverse harem or orgy?

So I’m working on The Visitor Rises, the next story in Gina’s continuing polyamorous apprenticeship. It’s looking as if it’s going to be a bit shorter than the first two titles in the series, and it’s going to feature a birthday celebration.

Now, obviously, it’s going to include fun times with her dancer boys, Sam, Jim, and Matt. But what I need help deciding is whether to include Marie the Porn Star, turning it from a woman-and-her-three-men reverse harem to a two-women-three-men orgy. And if Marie gets to play along, should I allow her and Gina to have fun together, or should the only bisexuality be between the boys? (Say that three times fast!)
