Vicki blinked the sweat out of her eyes and tried to gather her thoughts, which had been scattered to the four winds by the multiple orgasms she had been forced to endure. Not that she was complaining. She had never had such a night of ecstasy in her life. It was just that, given the choice, she would have liked to have had more recovery time between each of the climaxes that she had reached, the number of which she had lost track quite some time ago.

But she had had no choice. That was the point. She had surrendered her choices to the young woman she had met only hours previously, a mere slip of a girl who had turned out to be more confident and more controlling than Vicki could ever have imagined. With just the power of her voice, she had turned the older woman from an outgoing and self-confident divorcee looking for a one night stand with some young and naive stud, into her plaything, willing, even eager, to submit herself to the other’s whims and desires. There had been a promise of passion, both in the young woman's words and in her actions as she had first taken away Vicki's breath with her erotic touches, followed by her clothes as she had slowly stripped her, and finally her freedom as she had chained her to the bed. To all of this, Vicki had willingly submitted, intoxicated by the sensations she was experiencing.

Still, she was relieved when she felt the vibrator being eased out of her - it had done sterling work, but it was now starting to become a little uncomfortable. It also meant that she would be getting a break from the constant and seemingly relentless stimulation – or so she thought. She was shocked and rather alarmed when she soon felt the head of the device being pushed between her buttocks until it pressed against her sphincter.

She had never been penetrated by anything there - whenever the subject of anal sex had been raised by her creep of an ex-husband, she had always rejected the suggestion vehemently, making it abundantly clear that she found the whole idea dirty and disgusting. Now she was quickly finding out that it was also damned painful!

"Oh! Ah! Please, Mistress… Ow! It hurts!" Vicki screwed up her face as the silicone gel phallus was forced into her, stretching her tight anus painfully, then sliding up into her rectum until the whole vibrating length of it was inside her, making her feel uncomfortably stuffed.

The vibrations felt so strange, so alien, the same and yet so different from when they were in her vagina. She couldn't decide whether it was pleasant or not, it just seemed so weird. But then she found herself completely distracted from what was happening in her bottom by what was now happening in her pussy.

She felt Lucy's long, slender fingers slide into her, first just the index finger, but quickly joined by the middle and ring finger, all three wriggling around, sending the most wonderful sensations through her. She gasped and moaned as she felt the manicured nails scrape along the inside wall of her sex, causing her brief pain but stimulating the nerve endings so close to the skin to fire off their signals of pleasure directly into her brain. Immediately, she was in the grip of another mounting climax, and the chains holding her down rattled as her arms and legs spasmed convulsively. Only moments later, she screamed out as the orgasm swept through her, every muscle tensed, her back arched, head thrown back, hands grasping at thin air trying to cope with the rush of natural chemicals flooding her body. At last, she sunk back onto the bed, exhaustion replacing the exhilaration she had just experienced.

She opened her weary eyes to see that Lucy had raised the hand with which she had just brought Vicki to yet another noisy climax, and was gently but firmly pushing her wet fingers between the older woman's lips and into her mouth. Without a moment’s hesitation, Vicki sucked on the fingers hungrily, tasting her own juices for the first time since, as a pubescent teenager, she had experimented, in the way one might taste one's own blood when cut. Now, as a mature woman, she eagerly licked her cum from the palm of the hand before her, relishing the strong flavour and rich aroma of sex.

"Having fun, Victoria?" Lucy asked with a smile.

"Yes, Mistress," Vicki replied, returning the smile as she looked up at this amazing girl now sitting astride her prone body.

"Time for a little quid pro quo, I think." Lucy shuffled up the bed until her thighs were on either side of Vicki's head, her crotch directly above Vicki's face. Although she had never been involved with a woman before, Vicki knew what was now expected of her, and what would have seemed unthinkable a matter of hours before was now the least she could do in return for the delights she had experienced.

"Yes, Mistress," she murmured as Lucy lowered herself. Vicki went about the task of pleasuring her Mistress with eagerness and enthusiasm, driven not by a sense of obligation but by a desire to help this amazing girl reach some of the heights to which she herself had been taken.

Although performing cunnilingus was an entirely new experience for her, Vicki knew what she would enjoy herself, and sought to provide that to Lucy. So she delved deep with her tongue, stretching and twisting to reach the incredibly sensitive area inside, upon which Lucy had played so skilfully with her fingers inside Vicki. She licked and slurped at the juices which began to run freely, drinking them down greedily as Lucy became more and more animated above her, grinding her hips against the willing mouth below, crying out as she felt her clitoris sucked and teased mercilessly, delightfully…

Vicki couldn't see what was going on above her and, with Lucy's thighs clamped tight over her ears, could only hear muffled noises, but she knew that what she was doing was having the desired effect. Determinedly, she maintained her work rate even as the muscles at the base of her tongue began to ache from the effort. Her goal was to bring her Mistress to orgasm, to give her the best climax possible, and no minor discomfort was going to get in her way. A stray thought passed through her mind, questioning the surprising haste with which she had begun thinking of the other woman as her Mistress, but she firmly ignored it and pressed on.

She soon received her reward. Lucy rode her with increasing abandon, pushing her crotch into the face below her whilst pinching her own nipples and fingering her anus to maximise her stimulation. It wasn't long before she came, loudly crying out in pleasure, before slumping onto the bed beside her bound lover.

"Mmmm, you're very good at that, Victoria!" Lucy sighed contentedly, stroking the soft body beside her.

"Thank you, Mistress," Vicki purred, feeling proud that she had been able to provide satisfaction, "would you like me to do it again?"

"That's a very tempting offer," Lucy smiled, turning herself around and engaging Vicki in a long and languid kiss which suited the delightfully relaxed ennui which had settled on both of them.

"But I have a better idea," she went on. "There’s someone I want you to meet."

Vicki looked up in confusion, not understanding the remark, and watched as Lucy got off the mattress and went to the end of the bed, where she pulled away the black material which had intrigued Vicki when she had first entered the bedroom. To her amazement, she saw that underneath it was a steel cage and, inside the cage, a naked woman!

Utterly astonished now, she watched Lucy unlock the cage and the naked woman crawl out. She was taller than Mistress, with a much curvier body - larger breasts and wide hips - with long, straight, auburn hair tumbling down her back. As she approached the bed, Vicki saw that she was wearing leather cuffs and collar similar to those she herself wore. She looked slightly older than Lucy, though still in her twenties, and Vicki couldn't help thinking that she was like a younger version of herself.

"Anna, this is Victoria," Lucy said as the two women stood beside the bed, "Victoria, this is Anna, my slave." The woman smiled warmly at Vicki, who was struggling with the concept of being formally introduced to someone whilst chained spreadeagled and naked on a bed. She realised that the woman had been crouched in the cage the entire time that she and Lucy had been in the bedroom, so she must have heard everything that had happened. Somehow, that stuck in Vicki's mind as crushingly embarrassing.

"Anna," Lucy went on, "Victoria was kind enough to provide your Mistress with some intense pleasure."

"So I heard, Mistress," she replied with a smile.

"Don't get cheeky, slave," Lucy chided with mock seriousness, "in return, I want you to give Victoria an amazing orgasm - even more amazing than those she’s already had tonight."

"Yes, Mistress," Anna replied quietly, smiling conspiratorially at her new companion as she climbed onto the bed.

"And Victoria," Lucy said, "I want you to practice controlling your orgasm. You will not cum without my permission. Understand?"

"Y-yes, Mistress," Vicki responded nervously - she had never tried to stop herself cumming before, and had no idea how she should go about doing it. But she had been given a command by her Mistress, and she wanted above all else to be obedient. She felt a moment's surprise at that realisation, but it was instantly forgotten when she felt Anna’s tongue touch her moist flesh.

Almost immediately, she felt herself losing all control over her body. She looked down to see the auburn haired slave between her thighs, her head bobbing as she expertly teased Vicki with the lightest of touches, a kiss here, a lick there, a stroke of her long fingers, a nuzzle of her cute nose. Vicki groaned and panted under the virtuoso performance of the art of arousal, feeling like she was hovering somewhere above the bed, constantly aroused but nowhere near climax. It was a form of torture, but one she would never wish to stop…

As she felt herself slowly rising to yet another climax, she looked around for Lucy, thinking of needing to ask her permission in the near future, but she was rather shocked when she saw her. Lucy was standing by the chest of drawers from which she had brought the various toys which she had used on Vicki, and she was attaching some kind of harness around her hips and thighs, a web of leather straps, the purpose of which Vicki didn't immediately understand. Not, that is, until Lucy turned to face her and she saw the huge black phallus standing out from her crotch. It was the first time she had seen a strap-on dildo, and she found the sight intimidating, almost frightening.

She watched with trepidation as her Mistress walked towards her and then clambered onto the bed, kneeling behind Anna, who still had her head down between Vicki's thighs, and her rear end up in the air. Lucy positioned herself behind her slave and then spat on her hand, using it to lubricate the end of the dildo.

"This is my rather more pleasant version of the Human Centipede," she said, looking at Vicki, "and we're going to play a little game. We're all going to cum, but in the correct order. I will cum first, then Victoria, and I'm afraid you cum last, Anna. Understand?"

"Yes, Mistress," they both replied, Anna’s voice rather muffled.

"Then let us begin," Lucy concluded. At the same moment, she thrust the black monster deep into Anna’s pussy, pushing her whole body forward and forcing her face into Vicki's luxuriant pubic topiary.

Vicki found herself mesmerised by the sight in front of her. Lucy was gripping Anna’s hips tightly as she thrust rhythmically into her, grunting slightly with each deep penetration. In pose and actions, she looked just like a man taking a woman doggie style, but her slender form, her bouncing breasts, and the way that she bit on her full red bottom lip subverted that image into something altogether different and, to Vicki’s mind, altogether more beautiful.

Each thrust by her Mistress also intensified the effect that Anna was having on her, driving her tongue deeper, making each action deliver much higher impact on Vicki's hypersensitive body. The rhythm, transmitted from Lucy to Vicki through the body connecting them, also began to have its effect. It almost felt to Vicki as though she was being fucked at long distance by her Mistress, and her arousal became even greater.

Suddenly Vicki realised she had to get a grip of herself, otherwise she was going to cum before she was allowed, and that would never do. Unsure of what she could do to delay her climax, she tried distracting herself, thinking of the mundanities of work, the joy of playing with a litter of puppies, and taking part in a cookery competition – anything but sex. Unfortunately, her daydream about work ended with her spread out across the desk, being taken by two of her colleagues at once in a fantasy scenario she had never had before. The puppies pulled her to the ground and, having ripped her panties off, were merrily licking at her defenceless pussy. Even the televised cookery contest degenerated into a bizarre scene where the other contestants were sucking melted chocolate from her naked body - The Great British Lick-off.

Trying a different technique, she dug her fingernails into the palms of her hands, distracting herself with pain. This seemed to have some effect, but she could still feel the excitement building within her, and she couldn't cause herself enough pain to stop it.

In desperation, she tried meditation, finding a calm spot within her which was not impacted by the fireworks going off in her groin, and focusing on it, letting the feelings of impending orgasm go ignored. It seemed to have some success, but she knew it couldn't last long.

Finally, all she could do was stare at Lucy, willing her to cum to her rescue, as it were. Luckily, it seemed that she was close. Her face and chest were shining with sweat, her head thrown back as she pummelled Anna even harder, and she was becoming ever louder in her grunts, cries and, eventually, shouts of excitement.

It was a race not to reach the end, and one that Vicki felt she mustn't lose. She didn't know what Mistress would do to punish her if she failed, but that wasn't the point at this stage - she just didn't want to disappoint the young woman who had so quickly taken such an important role in her life. What had started out as just a rather bizarre one night stand had, for Vicki, become something much more important. She had discovered her submissive side, and had found that making love with another woman seemed so much more exciting than with a man. She wanted to explore these new facets of herself in more detail and, in order to do that, she needed Lucy to want her as her slave.

At last, Lucy screamed out in orgasm. Almost immediately, Vicki felt her own orgasm sweep through her, and she thrashed about on the bed, releasing the tension which had built up in her body. As the moment passed and, still gasping for breath, she looked down to see that Mistress was still fucking Anna hard, driving her to the final moment of release.

"Please… Mistress… May I… Cum?!" Anna gasped.

"Yes, slave, you may!" Lucy replied through gritted teeth, delivering the last few strokes which pushed Anna over the edge. She barely seemed able to cope with the sensations coursing through her body, looking to Vicki as if she had been electrocuted, every muscle tensed, her mouth wide but emitting no cry, just panting for breath, hardly able to suck in enough oxygen. Eventually her body relaxed and she collapsed onto the bed, her only movement that of her chest rising and falling.

"Just so that you are aware, Victoria," Lucy said, looking down at the prone body of her slave, "that was Anna’s first climax for over a month."

"Oh my God!" Vicki exclaimed, looking down at the other woman with renewed sympathy.

"Yes," Lucy continued, "and many nights during that time, she has been on the verge of orgasm. That is the level of self-control that a slave needs to attain. It's certainly a challenge…"

"Yes, Mistress," Vicki responded forlornly, sure that she could never perform that well.

"Now," Lucy said, getting off the bed and starting to unstrap the dildo, "time for sleep for all of us, I think. Victoria, you will sleep with Anna. In the morning, Anna, I want you to clean and present Victoria appropriately for me.  Now, off to bed with you both, and don't wake me up in the morning!"

"Goodnight, and thank you for an incredible, wonderful night, Mistress," Vicki said with a shy smile on her face.

"Goodnight, Mistress," Anna said quietly, taking Vicki's hand and leading her towards the cage at the end of the bed. She signalled for her to crawl into the cage and, feeling that the situation had become even more surreal, Vicki did so.

The floor of the cage was covered by a futon-style mattress, which was quite firm, but not much more so than other beds she had slept on. There were no bedclothes though - no sheets, no duvet, no blankets - and she wondered how she would cope. The room was warm enough to not need the coverings, but she was so used to the close embrace that she wondered if she would be able to sleep without them.

She heard a noise behind her, and turned to see that Anna had crawled in as well, and was now pulling the cage door closed. The lock engaged with a loud click, and Vicki realised that they were now trapped, imprisoned until Mistress decided they should be released. It was another new and curious feeling in a night strewn with them.

Anna lay down on the mattress and waved to Vicki to join her. Hesitantly, Vicki laid down, facing away from Anna. She felt the younger woman move her body up against her back, and then her arm came around her, lying across her belly, pulling her in close - they were spooning!

"Goodnight, Victoria," Anna whispered, her warm breath tickling Vicki's ear.

Vicki lay awake, listening to the other’s breathing become slow and regular, indicating that she had fallen asleep. But there was no way that Vicki could sleep, her mind was far too active. There were so many new things she had experienced in the last few hours, events and feelings which needed to be processed, questioned, assimilated. Her heart was still racing, excited at just the memory of what had happened.

She would have had to pinch herself to check that all this was real, except that she had the warm body pressed against hers and the arm draped around her to convince her that she wasn't dreaming. Yet it had all happened so fast that she was struggling to understand - was she really a lesbian? Was she really this submissive? Did she really want to be someone's slave?

In the end, she decided to just stop worrying about it. What she knew for sure was that she had enjoyed herself more that night than she could possibly have imagined. And, as she lay in the dark, being cuddled by the naked woman in the cage with her, her thoughts turned to what would happen in the morning. She decided that she really had no idea, but she was incredibly excited to find out. And, with that thought, she drifted off to sleep...
