Yes the first 3 things you mentioned were real but nothing else.
Now even when Becca and Megan started it was out of an artificial situation. What I mean is that none of the planned evenings are real, the Twins dancing in the afternoon, Kami and Kristy stroking each other on the couch day after day, Jess's exercising naked.
Feelings are real, the male/female fucks have been real but what happened with Rus, Jes and Irma was light years from reality. Belle got genuinely excited but at home I don't think she quite dances like that naked in front of friends.
