David invited Detective Maddox to make herself comfortable on a beautifully upholstered sofa. "What would you like to drink, Sue?" he asked.
"I'd love a gin & tonic!" she replied, smiling up at him.
He fixed her drink and joined her on the sofa, smiling at her as he handed over the glass. Flicking a switch on a panel set into the arm of the seat, another section of bookcase slid silently to one side, revealing a state of the art video entertainment suite. He pushed another button and the screen sprang to life, revealing a perfect shot of Kristy, bound and forced to cum over and over again. Her hair was now limp and damp and a sheen of sweat covered her body. David could feel his cock stir in response to the sight and from the way that Sue was shifting in her seat beside him, he was sure that she felt the same way.
"Well Sue, your quick thinking has delivered quite a gift to me!" he advised her. "I've had my eye on this one for quite some time and was wondering how I was going to gain access to her. You have saved me a lot of time and trouble!"
"Not at all Mast-David" Sue replied, then smiled wryly. "I'm still getting used to the fact that I'm not your slave any more!"
"Understandable, Sue," David replied. "After all, you were with me for 2 years, were you not?"
"Yes, and may I say that once you finished training me, I loved every minute of it! But I'm honoured that you feel I am suitable Mistress material." Sue replied.
"Well, as you have demonstrated tonight, you have what it takes." David explained. "I still require you to treat me with respect, but it shall be the respect of equals from now on."
They were distracted from their conversation by the muffled cries issuing from the screen as Kristy once again succumbed to an intense orgasm. The image on the screen was so clear that both Master and Mistress could see the tracks of the tears running down her face. It was obvious that pleasure was now turning to pain as her over-sensitised body was subjected to unrelenting stimulation. Looking at each other, it was obvious that they were equally turned on by the view the screen was offering. David flicked yet another switch and the screen showed Kristy's body start to relax as the unremitting stimulation ended.
"Let her have a break for a moment or two," he said to Sue. "I wish this evening to be prolonged and that will not happen if she continues like this. Let us savour our drinks for a while, before continuing with the evening's entertainment. One of the most important things for any master or mistress to learn is to gauge their slave's level of endurance. We need to be able to take them to their utmost limits without doing permanent damage," he explained.
As they both sipped their drinks, he continued to go into further detail as to the skills required to become a true Master or Mistress, and the level of responsibility required. Sue nodded, attentively listening to everything he was telling her. After about half an hour David glanced at the screen. Satisfied with what he saw, he once more flicked the switch that remotely controlled the vibrators attached to Kristy's body and was rewarded as she immediately tensed and a muffled groan forced its way past the gag. They could both see her desperately trying to twist her body away from the unwanted stimulation, but to no avail. The sight of her struggle once more had an effect on David and he turned towards Sue, the question in his eyes answered immediately as she stood and started to remove her clothes. As her breasts sprang free from the confinement of her bra, David could see by the hardness of her nipples that she was as turned on as he was by the plight of the woman held captive in the other room.
Her eyes never once leaving his, Sue removed her panties and moved to stand before him, offering herself for his inspection. He was pleased to note that despite making the move from slave to mistress, she was still keeping herself completely bare. He gently stroked his fingers against her vulva, feeling how hot and wet she already was. Sue moaned and pushed her pussy against his fingers, silently inviting him to explore further. David obliged and reached up with his other hand to pinch and tease her right nipple and was rewarded with Sue's gasp of pleasure.
On the screen, Kristy was rapidly being forced to yet another climax. Gently David turned Sue around, whilst keeping his fingers at work deep within her, allowing her to witness with him the image of Kristy's face contorting as she was sent over the edge. David could feel Sue shiver in reaction.
Sue looked over her shoulder at her former master. She knew what he liked best and also knew how frustrated he would feel until the new slave was ready for him. Over the years, David had schooled her in many ways and trained her to do many things, and she had learned to love offering him what he most desired. She sank down to her knees in front of him.
"David, I know that your new slave is unsuitable for your needs at the moment." she said. "I would be honoured if you would fuck my ass in her place."
David looked at her consideringly, aware that her offer was not completely altruistic as he knew she enjoyed the experience as much as he did. Nevertheless, he was touched that she should still use such submissive language despite her elevated status. However, the sight of Kristy bound and with all power taken away from her, forced to submit control of her body to mindless devices and the will of her new master was making him ache, his cock hard and pulsing.
Without a word he placed a hand between Sue's shoulders and pushed her gently forward until she was on hands and knees before him, her ass presented temptingly. He released his robe and let it slip from his shoulders. He moved his fingers across her vulva and then slipped them deep with her pussy, coating them with her juices, before withdrawing them and lubricating her asshole. Placing his cock at her entrance, he entered her with one firm thrust, rewarded by her gasp in reaction. As she felt him enter her, Sue pushed backwards, wanting his entire length inside her. David's fingers moved back to her pussy and with one hand on her hips, the other stimulating her clit and pussy, he started to thrust rhythmically inside her. Driven wild by the combination of his fingers and the rhythm of his cock inside, Sue could feel herself rise towards orgasm. David, playing her like a virtuoso, took his time, varying the rhythm, at times almost withdrawing completely before thrusting in again hard, timing everything perfectly. The sound of Kristy's torment provided a perfect compliment as together they rose towards orgasm. Finally, as he judged Sue was at the peak, his fingers firmly pinched her clit between them as with one final thrust he spilled his seed within her. Sue cried out as her body shuddered in the throes of a powerful climax, and wondered if her life as a Mistress could possibly reward her with orgasms as powerful as those she had experienced as this man's slave.
Slowly David withdrew. Sue remained where she was for the moment, too spent to move. She heard him draw on his robe and walk across the room, before the clink of glasses told her he was pouring them another drink. By the time he came back to the sofa, she had recovered her composure and accepting her drink from him, settled down at his feet to watch the continuing action on the screen. Finally David judged that his new slave had reached the limits of her endurance and turned the vibrators off. Drawing Sue to her feet, he assisted her back into her clothes.
"I think that our new slave has had enough for this evening," he said. "Get her off the table and remove the gag and vibrators, but leave the butt plug inside her. Oh and inflate it to its fullest extent. I intend to use her ass before this weekend is over and I do not want to have to exert myself. Then take her to the cell, remove her blindfold and lock her in for the night."
"I'll do that," Sue assured him and moved into the room where Kristy was bound.
David watched on the screen as Kristy's head turned blindly toward the sounds of Sue's footsteps. Without a word, Sue undid the harness holding the vibrators in place and removed them from her body. Tears of relief flowed from under the blindfold. Sue couldn't resist gently stroking her fingers over Kristy's clit and was rewarded with an anguished moan, muffled by the gag. Kristy's body was slick with sweat, making it easy for Sue to undo and slide the straps off her body. They had been so tightly fastened that Kristy was covered in red marks where the straps had dug in. Finally Sue moved to Kristy's head and undid the strap over her neck before lifting her head and undoing the ball gag, having to physically open her mouth to remove the ball.
"Thank you Master!" Kristy murmured weakly.
Sue nodded to herself. The first step had been taken, even if Kristy didn't realise it. She had thanked her master without having been reminded to do so!
"Good effort, slave, but your master is not here. However, you are being released at his command and I shall pass your thanks on to him! You may address me as Mistress S" she told the subdued woman lying before her. "Now on your feet!" she commanded.
Kristy tried to obey but was so weakened by her ordeal and disoriented by the blindfold that she still wore, that she fell to her knees on the floor.
"Very well, slave, as you can't even obey a simple command, you will crawl to your room!" Sue's voice cracked out.
"But I can't see where I'm going!" Kristy cried.
"That is easily corrected!" Sue's voice purred silkily in her ear.
Kristy jumped as she felt something wide being placed around her throat. With a click behind her, she realised that she had been collared! Another click and she suddenly felt herself being tugged forward. Tears of humiliation flowed down her cheeks as she was led like a dog towards an unknown destination.
It felt like an eternity as she was forced to crawl on hands and knees behind the woman she knew as Detective Maddox but was coming to realise must now address as Mistress. Finally she heard the sound of a door opening. She felt herself being pushed inside and stayed where she was, unsure of what was to happen next. She heard noise that she could not decipher and tried to turn around, only to be brought up short as her neck was yanked backwards. It seemed she had been tethered in place. Then she felt wide bands of leather being wrapped around her wrists, followed by a pair of clicks as they locked into place. She then felt two more bands of leather being wrapped around her ankles and also locked into place. Then she screamed as she felt the butt plug, which had not been withdrawn at the same time as the vibrators, inflate once, twice, then a third time, stretching her unmercifully.
