Becoming Maria's Personal Duct Tape Slave

In this video inspired by old Insex videos, sisters Katherine and Maria Martinez play a game where the loser faces consequences and becomes the winner's personal bondage play-pet. Maria becomes the Master of her step-sister Katherine, who is turned into a duct-taped slave girl. Maria whips Katherine's ass and makes her crawl around on the floor. She parks Katherine on a bench, puts a cup of water on her back, and reads quietly.
