You and your roommate are so competitive and love to play games with each other, so today she propositions you with some rock paper scissors. You suggest upping the stakes and make it strip rock paper scissors, she's nervous but accepts! Lucky for you you're on fire, winning each round as she takes off all her clothes until she's butt naked... all except for her buttplug that she was wearing that day. You didn't realise your shy housemate was into that stuff! The loser of the final round has to do anything the winner asks of them, you get lucky one more time and get to play with your roommate until she cums.
