It was Grace’s first day with her new guardian and he’d already decided that he’d be fucking her ass for three hours each day instead of using his treadmill. He said that he could really feel it working his core and that he was sure they were both burning a lot of calories. She whimpered and moaned the entire time his cock was up her ass, every time, but managed to agree with him, like a good little slut. She was glad that she’d be getting so much attention and was sure it would help her become a better slut, while also helping to keep her guardian, who she was only allowed to call sir or master, healthy. It was a win-win situation for everyone.
