Agree with your assessment dukefan but unless its very good acting the blonde in white doesn't want to have her pussy displayed to the crowd when she is sitting on the chair and pushes his hands away. She was happy to give blowjobs earlier but also pushed the guys hands away when they tried to finger her. So the fact she's convinced to eventually bend over and take it from behind could means she's not necessarily a plant. But countering that she has the ribbon bow tatts on her calves and other tatts on her neck so maybe she is.
