Dom Rider
Rider's smirk grew broad as she heard the girl's pained yelp, followed by the reply, which was still defiant despite the obvious pain the captive girl was in.
This is going to be fun, she thought, her arousal growing as she pondered how to punish the girl's disobedience.
"I see...", Rider said, sadistically. "Very well, then."
With that, she pushed her hand towards the girl's mouth, rubbing her damp fingers against her lips, before running the hand down the girl's face and chest, leaving a small trail of her own juices on the girl's face and neck. Then, releasing the girl's now-sore nipple, she grabbed hold of the dress with both hands and pulled down as hard as she could, tearing the fabric connecting the main part of the dress to the strap. Then, she pulled her arms apart, tearing the dress down the front, before letting go and allowing the now-useless garment to fall to the floor, leaving Emily now entirely naked before her.
Rider moved away from the girl and walked around to her front, standing back slightly and taking a few moments to admire the view, licking her lips at the sight of her highly-attractive slave's nude body. Her arousal began to increase even further as she looked over the bound and naked girl, knowing that the red-head was now at her mercy.
After a few moments of drinking in the sight of the girl's naked body, Rider moved in towards her once more. One hand moved up towards the girl's now-bared breasts, beginning to grope one and then the other, far rougher than before. The other hand, meanwhile, moved down to her damp folds. She began to rub the girl's folds gently before, suddenly, she thrust several fingers abruptly into the captive. Then, she reached up with her thumb and began to vigorously rub the girl's hardening nub.
She continued to pleasure the captive until she felt the girl's nipples fully harden. Then, after giving one of her nipples a quick tweak to test their sensitivity, enjoying the sound the girl made, she removed the hand from the captive's ample mounds and reached into her pocket. Then, she pulled out a set of nasty-looking toothed nipple clamps, designed to painfully crush and almost pierce the sensitive flesh, which she had picked up from the wall earlier, all the while continuing to pleasure the captive.
"Let's see how you like this", she said as she brought the hand containing the chain-linked clamps to the girl's breasts, a sadistic grin on her face.
With that, she took a clamp in one hand, opening it up and placing it over one of the girl's nipples. Then, she released her grip, allowing the device to clamp painfully onto the hard nub. Running her hand down the chain, tugging slightly as she did, she reached the other clamp, taking that into her hand and bringing it up to the girl's other nipple, then repeating the process.
