Well, I wasn't saying for them to do anything for any of the guests other than dance, if they want to get a happy ending, they can buy their own slaves!
We have Peni who already volunteered to dance for us, I am sure Ann would be happy to, a number of the girls really get off on being seen, so are not likely to mind that much. And all of them have the exhibitionism stat, which can be trained up, which should be used to unlock such scenes, as well as the submission.
As for the narrative, they are going undercover, like
Maria, it's just a game, to help hide what they are really doing.
