As the night wore on, Sarah felt a pang of guilt for how much she had pushed her human pet that day. He had been through so much, and she knew it wasn't fair. But he was her pet now, and she had to train him properly.
Softening her heart slightly, she untied him from his restraints and let him collapse onto the cold floor. He looked up at her with exhausted, tear-filled eyes that made her chest ache.
"There, there," she cooed, running a gentle hand through his disheveled hair. "It's over for now."
With a deep breath, she reminded herself of her duty as a mistress. She couldn't let him off easy - not when he still had so much to learn.
