I need to get back to the party

Karen is a great lay but only one of what you hope will be many. After what she said, you totally own her. You don't want to be exclusive. You're only 18 with lots of partying left including tonight you hope. You tell her that you have to go back to the party to pick up your friends. You are taking her back to the party as she has to pick up Amber's car. Do you give her a ride back or take her somewhere else?
