We first met Doctor Robyn in Chapter 16 of the Hanson House series. She also starred in her own sequel.
*****************************
"I don't know what to do Doctor," Ruth pouted. "Am I doing the right thing?"
Robyn responded with calm. The nature of her unorthodox therapy sometimes led to a patient having second thoughts.
"I'm still a married woman," Ruth went on. "Should I go on being... being a slut?"
"The world sees you as a respectable, married woman," said the Doctor quietly. "But your therapy has brought out your other side. That secret side. Are you ready to give up all these sexual adventures?"
"I know I can't," Ruth whined. "I need it... my new sex life has made me a new woman. But the guilt..."
"I told you from the start that sex with others is vital to your therapy," the Doctor explained. "And you're also doing a service for other patients."
"You mean Bella and Dan? But I don't want cause any problems in their marriage."
"Like you, they've realised that a loving partner might not satisfy all their needs," explained Robyn. "The difference is they perform their therapy as a couple."
Ruth's dreams and secret desires had centred on being forced and used. She almost shuddered at the wonderful memories of Dan and Bella. It should have been therapy but she'd felt exquisite pleasure from being Dan's first anal conquest -- and letting him have her arse in front of his wife had been delectably perverted.
"Your sexual needs are being met," continued the Doctor. "And you have the opportunity to do the same for others."
************************
Ruth knew that her new friend Deepana had benefitted from the good Doctor's deviant therapy. Surprised to so quickly have embrace lesbian sex play, Ruth had accepted Ruth's explanation that it was just another side of her submissive inner-self. Besides, she enjoyed the touch and feel of a woman more than she'd have thought possible. Deepana had been clumsy at first. Ruth had enjoyed every second nonetheless. She'd been thrilled to overcome another taboo. Ruth loved to lose herself in the joy of pleasuring both holes of her dark-skinned lover.
Now Deepana was almost shaking with nerves. Ruth had finally convinced her that there was nothing adulterous about helping a friend to pleasure her Master.
"Remember what you said. Its not cheating if you're just helping," Ruth reminded her. "Its just a blow job."
"I am keeping my clothes on the whole time," Deepana stated for the hundredth time.
Master Peter had taken some time to grasp the opportunity. He's come around to the idea of including another female after seeing the benefits of his friends using Ruth's slutty mouth. In return for that experience, had wanted so much to give him a special gift.
Inside his house, Ruth performed her familiar ritual -- disrobing easily and sinking to her knees before her gorgeous Master. This time there was extra rode at being watched by her fiend as she slipped the soft collar aorund her neck. Peter did not always make Ruth wear it but this was a special occasion. Deepana could not hide her shock at how easily the white woman exposed herself.
"You're not joining her?" Peter asked with a grin.
"I'm a married woman," replied Deepana shakily.
It was a strange answer since her friend also was married. Peter chose to focus on Ruth for the moment. He always was turned-on by Ruth's eagerness and her still sexy body. His signal was what she'd been waiting for. Practised fingers opened his jeans and extracted his hard cock -- a generous seven inches with the girth to match. Ruth herd the tiny gasp from Deepana and proudly wrapped her fingers around the Master's magnificent pole.
"I told you," said the white woman with a wicked grin.
Ruth caressed her Master's cock, proud to show it off to her dark-skinned lover. She knew it was the biggest penis that Deepana had ever seen. And it was her Master's weapon.
"Please, Master," she whined while gazing up at the wonderful younger man.
Peter gave another signal. He didn't want to wait, especially not that day. The dark-skinned woman was intriguing. It was fun to watch her reaction. But she was nothing compared to his sex slave -- the conservative, older woman who so much enjoyed giving her holes to him. Ruth slipped her mouth down his length. She was excited by Peter's moan of pleasure. It was more fun to display her cock-sucking talents to her friend.
"Oh my..." breathed Deepana as she watched her white lover manage the big shaft in her mouth.
She was astonished by the wanton display. Aroused by Ruth's eagerness. And entranced by the way Ruth's mouth stretched around that massive white cock. It made her nervous that Master Peter was looking at her while his cock was being sucked. He was turned-on by the chance to have two women. Deepana had promised herself that she'd do as little as possible. But she'd not counted on the temptation of the biggest, whitest cock of her life.
"She is a good little slut," Peter commented to Deepana.
"Yes... yes she is..."
Deepana did not know what else to say. She was a witness to adultery. But it was such a fine cock.
"More," Peter ordered Ruth and helped with a gentle hand on the back of head.
Deepana saw how casual Ruth was with complying the commands of her Master. She herself had helped teach Ruth to obey and to pleasure her soft, brown-skinned body. And Deepana, of course, eagerly sucked her husband. But her white lover was especially eager to give adulterous oral service to this man. Deepana was beginning to understand the temptation to succumb to his quiet authority.
"That's it, slut," he was saying to Ruth. "Show your friend what you can do."
Having watched that fat meat strain Ruth's straining mouth, Deepana was agog as the other woman took her hand. Relinquishing her Master, Ruth slowly drew Deepana's small hand to that prodigious manhood. The dark-skinned woman had wanted to ignore her curiosity for a new cock. She'd insisted that she was only going to watch. But she could not make herself resist. And at the first touch she felt her fingers closing around the stranger's shaft. She gasped again, impressed by the heat and the hardness. The stranger was throbbing nicely.
"That feels so perfect," Peter breathed to the dark-skinned woman.
Deepana could not stop her hand instinctively working up and down his length. Peter could hardly believe his luck. It had been pure accident that he'd found himself in this new circle of deviant sex players. Group sex and gang-bangs had been an unexpected joy. As had the admiration of his new friends as they took the chance to use his new sex slave. It was his sexual dominance, though, that had been released. The opportunity to control and use a willing submissive. How much better it was to have his straining cock being worked on by two women.
"Very nice," he breathed to the sexy newcomer as her dark skin contrasted with the whiteness of his bulk.
"Its impressive," was all that Deepana could say.
She wanted to remain calm and dispassionate, reminding herself that this was a favour to her friend and, thus, not cheating on her husband. But she could not ignore the truth that she was handling a new cock. This was like cheating twice over -- a married woman stroking a cock that pleasured her adulterous friend. But the hard shaft felt amazing in her hand. It was alive with its throbbing and twitching. And she could hardly believe that Ruth's holes could accept something so big.
Peter watched with his own lust and rising excitement as Ruth moved behind the dark-skinned woman. He saw the flicker in Deepana's eyes as his slave began to unbutton her dress. Yet there was no protest -- the brown woman seemed to accept being exposed in front of a man who was not her husband.
Ruth had insisted that neither woman would don underwear. It proved a very good idea now that she released Deepana's bare breasts. The soft brown body provided a delicious contrast. The perky, sexy C-cups were smaller than Ruth's tits but irresistible all the same. Deepana was unable to protest as Peter began to fondle them.
"Very nice," he said softly.
"Thank you, Sir."
Deepana did not know why she said that. But his gentle touch was firing her desires.
"Told you," said Ruth to her Master.
She was proud to show off her lesbian lover, to share Deepana with Peter. Just as she'd been proud to be shared with his friends. With her own lust sky-high, she joined her Master in groping the increasingly aroused Deepana.
He had the sense to watch closely as Ruth groped the juicy brown boobs. Squeezing gently and hefting the soft, new flesh, he copied the way Ruth toyed with those dark chocolate nipples. There was no mistaking how much Deepana enjoyed having both pairs of hands on her married body -- the heaving of her chest and the quickening of her breathing betrayed her pleasure. Peter thought to himself that Ruth could not have brought a better friend as he enjoyed those perky, brown tits. Nor could he ignore that Deepana had increased the pace of her stroking on his cock.
The brown-skinned woman had been certain that she'd stick to her plan. But she forgot her pledge as Ruth removed her dress entirely. Deepana was nervous -- almost ashamed -- to be naked before a man who was not her husband. Of course, she wanted to make her friend happy. Not to mention Peter, obviously excited to ogle her soft, brown body. Two naked bitches were inspiring for him.
"You want to watch me fuck this bitch?" Peter was asking Deepana.
She marvelled at Peter's and calm, firm manner. Deepana saw now why Ruth found it so easy to submit to him. And she very much wanted to see Ruth succumb to some adulterous fucking. It was the real reason she was there.
"Oh, yes... yes, I do..." gasped Deepana.
"She will get on the bed now," he explained. "And you will prepare her cunt for me."
<><>Ruth moved easily into position, lying on her back and beckoning Deepana to lie between her legs. Her plan all along had been to give Master a lesbian show. She wanted Deepana to see her straining to take that massive cock in her tight, married cunt. But first Ruth needed some attention on her have cunt. She moved her shapely legs further apart.
