His words made both of the women laying over the desk shiver. But they did not try to rise.

He stepped over and took the Hitachi Wand from his sister, turned and handed the device, its head glistening with his sister’s juices, to his slave.

He pointed to Beth and instructed her, “I’m going to discipline this one while you use that on her cunt.

I will only stop when I’m satisfied that she has learned not to abuse other people’s property.”

His words were intended more for the two women than Sherie and they knew it. Both were more naturally Dominant than submissive but still the thought of it made them wet.

Sherie crossed over and knelt between the two. Smiling up at her Master she turned the Wand on and its hum loudly filled the otherwise silent room. She put it up near the glistening folds of her tormenter’s vulva, and at a nod from Derek, pressed it into them.

At that very moment the first of the riding crop’s blows landed, causing a squeal from its target, she pressed it into her, just above her clit. Watching as he raised the crop again she withdrew it slightly and as it descended, pressed it back in.

“I don’t hear any counting, ” he said, “I guess I’ll have to start over.”

The grunting apology from the woman was music to Sherie’s ears, “sorry, Sir...”

Sherie was enjoying this sudden change of power and was in no hurry to make the woman cum. She avoided contact with Beth’s clit almost entirely but kept the powerful vibrator in close contact with the lower part of the woman’s vulva, only touching that swollen knob for a moment as the crop made contact. She was in no hurry to make the woman’s punishment end and found the newfound power exhilarating. Beth’s counting and breath became increasingly ragged as the crop landed again and again, leaving her shapely bottom criss-crossed with red lines. But she took it like a trouper and never lost count.

At eleven the Dominant nodded at his kneeling slave and she understood that it was time to let the woman cum. She pressed the bulbous head of the Wand against the swollen and over-sensitized clitoris as her Master struck four more times with only a few moments between them.

Beth grunted out, “twelve... thirteen... fourteen... fif—... ahhh!” before her ability to speak was usurped by the powerful orgasm that shook her body from her toes to the crown of her head. Sherie moved the vibrator in and out against the nub, making her cum again and again until, at a nod from her Master, she stopped and switched it off.

She looked up at her Master and could see that he was very proud of her. He smiled with that twinkle in his eyes that had made her want to open her body to him on their first date, and her heart to him on their second. And in time, surrender her body and freedom to him willingly.

The sweat-coated woman let out a long sigh and whispered, “Thank you, Sir. I think I needed that reminder. And I promise I will never abuse your property without your permission.”

“Well, sis, I guess it’s your turn.

“It’s been a long time since I’ve had you like this but I still have fond memories.”

Joanna looked over her shoulder at her handsome brother and whispered, “Me too.”

“I’m going to give you the same number as I gave her. But, if you don’t cum before I reach fifteen, I’m going to double it and if you don’t cum before that I’m going to add another fifteen.”

He knew that his perpetually aroused sister would definitely cum well before he added the extras but

knew the power of the threat would add to her excitement.

He winked at Sherie as she turned the vibrator back on and she pressed the round head of it into Joanna’s already soaked vulva just as the crop laid a vivid red stripe across her ass.

Her reaction was bestial, a grunted, groaning sound like that of a feral beast.

After a moment she gasped, “one...”

The next two came in rapid succession, catching her off guard and forcing a little squeal before she added, “two... three...”

Sherie look up at his face for some sign but only saw a wide grin as he sadistically struck his sister’s beautiful fair skin again.

She had heard about their teen-aged games but had not even tried to imagine her boss submitting like this to anyone, even her Master. But it was thrilling in a way that was new to her.

After the eighth lash, he looked at his slave and nodded, silently telling her it was time to make his victim cum.

She pressed the throbbing machine directly against the hood of Joanna’s clit and rubbed it up and down to push that covering aside and make direct contact with that super sensitized bud.

The woman being cropped erupted in a powerful orgasm as her brother added three more in quick succession. She tried to keep up with the count, but could barely get the whole words out : “fi... si... sev...n”

By the time she gathered herself together, her brother and his slave had long gone. Beth lay next to her, her eyes glassy in her endorphin filled haze.

With his finger through the D-ring at the front of her collar, Derek dragged the naked slave out of the office, into the elevator, and down to the parking garage, never saying a word. Sherie was of course, terrified. His silence was worse than if he had yelled ate her or punished her but she knew better than to say anything,

The elevator reached its terminus and she was led out toward his car, one of only two left in that garage, the other being his sister’s.

Reaching it he pushed her to the ground where she immediately took up the presentation pose. Only the sound of his zipper made her look up just in time to see his rampant manhood be pulled from his jeans. Without being told, she opened her mouth and stuck out her tongue.

She was not surprised that punishing the other two women had had this effect on him. She’d often and proudly worn stripes that he had administered just because he found it arousing. He made no secret of the fact that as well as being a Dominant, he was also a Sadist. Sherie had more than once wondered to herself if that made her a masochist but in the long run decided that she really wasn’t. She didn’t “like” pain. If she stubbed her toe it hurt but did nothing to arouse her.

But if it was pain being inflicted by her Master because it excited him... that, she adored. Every stroke of his cane, every lash of his whip or cat o’nine tails, every clothespin and clamp, every zap from his TENS unit, every needle pushed through her nipples, every thing his dark and twisted imagination could come up with to inflict pain, that, she adored. That, she lived for. She decided that though she wasn’t really a masochist, she was definitely a painslut.

He shoved into her open mouth and forced his erection deep into her throat. She had worked hard to learn this skill, to take him all the way without gagging. She had learned to take short breaths between his thrusts so that he could just facefuck her until he was satisfied.

His fingers entwined in her thick hair and pulled it, controlling her even more. Using it to hole her in position as he took her throat in nice long, even strokes.

As she often did, she drifted into her subspace. That cocoon of her enslavement that let her escape from all of her thoughts, all of her fears. She was nothing more than a receptacle for his lust and within that she found bliss. Of all the women he could have chosen for his wife and, more importantly, his slave, he had chosen her.

She could feel the muscles in his shaft pulse against her tongue and felt him slowly but steadily increase his pace. She used the tip of her tongue to tickle the underside of his cock’s head and sucked hard on every out stroke. While she wanted it to last forever, she also longed for the taste of his delicious semen. He had used it to train her, withholding it when he wanted to punish her, and letting her drink it when she was to be rewarded.

This was neither, so he might withdraw as he came and spray it across her face. Not quite as enjoyable since it meant she had to lick it off of her fingers but she was still very excited.

She felt his fingers tighten in her hair as he rammed into her faster and faster until she could only relax and keep her tongue out of the way as he throat-fucked her.

And finally, she felt the muscles in it contract followed by his hot seed hitting the back of her throat. She sucked hard as he withdrew just enough to fill her mouth with the thick fluid. He paused there, giving her time to suck every drop from his shaft before withdrawing.

Using the ring on her collar he lifted her to her feet and turned her towards the roof beam about 2 meters away, pointed at the small black lens and said, “Wipe the cum off your lips and wave ‘Hi!’ to your fans in security.”

The girl blushed, not with embarrassment, she was long past that, but with pride. She used her finger to wipe the few drops that had escaped her mouth, smiled at the camera, and licked the finger clean in as lascivious a way as she could. She waved, and mouthed, “hope you like that” at the camera.

Derek used his key fob to open the trunk and with his fingers, turned her and directed her to climb in. She was slightly disappointed but realized that her sweat-coated skin and leaking pussy juices would not have been kind to the car’s soft leather seats. She climbed in, lay down with her back to him, and offered her wrists up to be cuffed.

Only the lid closing and plunging her into darkness told her that he was not going to cuff her this time. It was as high a compliment as she might have wished for and she smiled to herself and whispered, “Thank you, Master.”
