Four brothers and sisters invited each other to commit incest

Charly and Mickey were holding the game console and wouldn't let Billy or Joshua play for even a second. To settle the score, the group of step-siblings make a deal and whoever gets the highest score in the game gets the console for the rest of the day. After Billy and Joshua win a landslide, they get the bright idea to bet on a bargain – If Charley and Mickey let them have sex, they could have the console for a whole month.
