Tim stopped circling slut's suspended form when he noticed her hardened nipples. This slave was loving this, He thought encouragingly. He couldn't resist the urge to reach out with his thumb and forefinger and pinch her left nub, just slightly. Instantly she breathed in deeply, making Him smile confidently, knowing she was no amateur, so He pinched a little harder. His new slave threw her head back, writhing from the delicious pain. As a reward Tim copied this procedure on her other nipple. The heavy breathing doubled as she arched her back.
Spurred on, the black-leathered Dominant twisted both nipples as hard as he could. He was pleased when He heard slut's sharp yelps echo around the walls of the dungeon, but He knew she was loving this. Looking down, Tim could detect some glistening between her legs. He smiled wide. He indeed had purchased a diamond-in-the-rough.
