Strip Rock-Paper-Scissors with Mariah and Liliana
Blonde Liliana and tan-lined Mariah play a really simple, really quick game of Rock-Paper-Scissors. Straightforward and uncomplicated.
They keep playing when naked, and when a naked girl loses again, she gets paddled.
Personally, I like tan lines. They emphasize the fact that you're seeing something the girl normally keeps covered, even at the beach.
