While we don't specifically say it, in my head these two gamers are step-siblings that have the hots for each other, but if they made it obvious their parents would never leave them together alone. They argue and bitch and pretend to fight until daddy is so fed up he's out the door, then they they're immediately stuck together like glue, fucking like rabbits until someone gets home and they have to scramble to get clothes on and act like they hate each other again.
