The girl you're holding hostage, is very bored and stressed after being left chained up in your caravan for weeks. She starts to masturbate multiple times a day just for something to do eventually struggling to slip her shorts off so she can play easier. She always makes sure she's finished and dressed before you come to check on her. What she doesn't know is you've got cameras in the room and you're watching her the whole time. Now you know what a trashy slut she really is you're even more glad she's yours to use.
