What happens when Winter and Lauren go to a private party hoping to find GS in Chapter 15?

Winter goes with Lauren and a caravan of sixty other girls to GS's mansion for a private party. Winter is "selected" by the bodyguards through a ridiculous competition to be GS's girl for the night. She enters his dark bedroom, makes love to him, but wakes up alone. She discovers the house is a rental for a music video and is sent away by the director.
