(This is virtually all a true story and I tried to write it as 3 different first person narratives but didn't like how difficult it was to keep track. Some of it is from the two subs that was given to me as lost letters. I've kept the changing fonts as a way to maintain at least part of that)
It was his slave's idea for them to get another slave together. Numerous threesomes had given her a taste of the excitement of Dominance and she was curious to explore it further. But it was more than that. In a few months she was returning to her home in South America for a few months and she wanted a girl to take her place at his feet.
Their relationship was not monogamous, just discreet. It was assumed that while she was away he would indulge his sexual needs as he might. She never asked about it just as he never inquired as to her outside explorations.
Their Master/slave bond was much stronger than any a casual fuck they might enjoy while apart.
As a symbol and reminder of her role she wore a chain around her slender waist that fits snugly enough to make its presence always known. It has no clasp and no lock. The end links had been fused closed so that only by cutting could it be removed. To an outsider it looks to be just a curious bit of jewelry but to them it was so much more. He also wore a bit of the same chain as a bracelet, it too fused about his wrist.
Their Dominant/submissive relationship was more than roleplay, it was who they were. And yet they were able maintain a general equality in the non-sexual parts of it.
He didn't realize at the time that she had an ulterior motive in her suggestion, one that made sense when he thought about it. She felt much more comfortable knowing who he was fucking and Dominating then imagining some unknown beauty.
And having a say in who that would be was another factor to put her at ease and give her a feeling of confidence.
Lu and Stan made no secret of their Master/slave relationship. Even besides the chain she frequently wore locked around her throat it was their interaction in private and in public that made it clear to even the most casual onlooker that she had surrendered herself to him.
They were discreet about it to varying degrees among their friends and acquaintances. Some, mostly the women, were curious about its inner workings. The fact that they were equals in their day to day relationship and yet property and owner in their sexual one was intriguing to them. Enough so that frequently it ended with them joining in a tryst. Depending on their penchant and often long hidden fantasies, they would join them as a Domme over Lu or, far more often, as her sex slave sister.
The men were far more pragmatic. Interested in the limitations of his Dominance. Was she whipped? (Yes, quite often.) Was her slavery exhibited? (Again yes, also quite often.) Could she refuse his orders or requests? (Sure, but since accepting his collar, she had never done so.) Like the women, they longed to join us. But they were even more shy about broaching the subject. He left the decision up to Lu. If she found the idea of inviting either sex appealing she'd let him know and let him guide the scene.
Drugs were very much a part of their activities, both social and sexual and were frequently included in the latter.
With most of their friends around getting high they went in the bathroom so they could start fucking just as the rush hit. With others, however, that they were interested in playing with, it was quite a different story.
When they set their eyes on a target they didn't stand a chance. The Master was quite good at spotting curious submissives and if she saw a guy or girl she wanted to submit to, he was always in favor of it.
They had discussed their friend Tim before but no opportunities had yet presented themselves. Until that night. They were pretty sure he was interested but he was too good a friend to say, "Stan, I'd like to fuck Lu."
Using the excuse that he had a fresh delivery of Peruvian product he wanted them to try, he came over. And though no mention of it had been made directly, there was a distinct sexual tension in the air.
They shared their taste for stimulant drugs and after doing a line of his exceptionally pure cocaine Stan sat back and ordered Lu, "Take your clothes off and come here and suck my cock."
Without a moment's hesitation she was naked on her knees before him fishing his cock out of his jeans. She adored my penis. She drew pictures of it and wrote poems about it. Being given permission to pleasure it was always a special treat. When she was in the mood for it she would negotiate an exchange, purchasing his blow-job with her pain.
Tim was startled but intrigued and clearly turned on. Lu was proud of her obedience and never hesitated to show it off.
After a moment, he pushed her back on her heels and said, "How rude of me. I was so horny I completely forgot our guest.
"Tim, would you mind letting Lu suck your cock?"
She and her Master exchanged smiles.
"She's already told me she'd like to."
In a flash she was between his knees opening the front of his jeans.
"One sec..., " he told her.
Stan picked up the polished stone they'd been snorting off of and still held a sizable mound of white powder and handed it to him.
"Do a line just as she starts."
With her Master to practice on Lu had perfected the drug rush blowjob. She took just the head of his uncircumcised cock in her mouth, teasing it gently with her talented tongue.
"Just rest the stone on her head, " he instructed.
This was something that they had discovered accidentally out of necessity one of the first times they'd done it and that she later revealed excited her very much. It was in part being objectified like a piece of furniture but also, she said, not being able to see his face made her focus all of her attentions on the cock in her mouth.
As soon as she heard Tim start to inhale she sucked as hard as she could on his shaft and as he continued she steadily took more and more of it into her. Until, by the time he finished, the tip was buried deep in her throat.
His was about the same length as her Master's but had a more circular cross-section. He was able to fill her throat with it. Stan's is wider horizontally than it is vertically and he can't get his past the cartilage at its entrance without it hurting but it does more effectively block her breathing.
She soon had Tim shuddering with arousal and Stan quickly removed the polished agate and its pile of cocaine.
