Your Step-Sister wants to apologise for trying to blackmail and trick you into being her ass slave with an offering of new headphones. You put them in and she begins playing relaxing music, you could really get used to this. Soon you can't help but do whatever she says, it worked! She finally found a way to get you under her spell. She begins teasing her ass in yoga pants then strips them off to reveal a thong. She quickly removes it and makes you kiss and lick her ass like a good slave. She stuffs the thong in your mouth and tells you that your job is to be her dirty panty washer. You do as you are told while you watch her spread her pink asshole in your face over and over making you even more weak. After some time and lot's of dirty panty sucking she leaves to get ready for her party. Before she heads out she reminds you of your role and that you better follow orders or else she'll use the toilet slave spell on you next. She'll be home later with a new dirty thong for you to suck clean.
