Jerking it for my ass is one thing. Cumming for my ass is another. And jerking and cumming until I tell you to stop is the ultimate challenge. Goddess Sydney wants to play a game with you. Don't worry, this will be fun for both of you! She knows how obsessed you are with her ass and how much you love jerking off to it, but really how much do you think you can jerk for it. Most ass slaves say they will jerk but they eventually tire themselves out. But that's going to be the challenge today, she wants you to jerk throughout the entire video, non stop! She doesn't care if you get tired or your arm starts hurting, you're going to start jerking as soon as you see her glorious butt and you're not going to stop, so make sure to pace yourself. That's good, keep stroking. Look at that amazing ass, don't you feel lucky for the privilege to get to jerk for it? Some men are locked up by her right now and can't even have that! So keep jerking, keep edging and stroking and don't stop no matter what. Even if you accidentally cum in the middle of the video, you have to keep jerking! This is a good practice for you and will teach your body some important motor skills. Besides, there's no other ass you want to jerk to more, is there?
