Three women with male slaves

English is not my birth languages, so please excuse any grammatical errors.

Three women - each with a slave husband - meet at a cottage for a weekend of pampering and wellness.
The slaves serve the women no end with pedicure, massages, fetching all and nothing. The slaves serve the women sexually with a lot orally actions, while the slaves are locked in chastity tubes. It is all about the women's pleasure.
When the women decide to exchange slaves and also find a bamboo cane all thing spices up.

Extract:
The women had dropped their towel. Because of the heat it was good to lay naked in the shadow, and their bodies were exposed for massage.
In no time three women were lying and sighed of well being as the slaves began their massage task. The three women's bodies were soon glistened of massage oil as well trained hands kneaded their muscles. The three slaves became soon aroused by the sight of those well built women bodies which only became more and more inviting as their skin softened under the massage. The slaves' arousals were extending by the fact that any of them hadn't had a relief for 24 to 28 days. All three women thought it wasn't good to spoil a slave with too many orgasms. A slave had to earn a relief by deliver a perfect service, and when such weekend as this lay ahead the women wanted the slaves at highest motivation and it would mean no relief several weeks before.
With other words: the pressure in the chastity tubes were at the highest.
None of the women had problems with that. It only increased the fun in a femdom relationship. In the beginning the women could have taken pity of the slaves, but long ago they had crossed the line of worrying about a slave's need. What matters was a woman's needs and well-being.
Three kneeling slaves were in full concentration to give the perfect massage. They were in for a full body massage with special attention on the woman's buttocks, which was a special sensitive part.
Now and then a woman raised her head and sipped at her glass of champagne.
Surely it was a lazy afternoon. It exuded womanly well-being, satisfaction, enjoyment and when the women were satisfied a femdom life was in harmony and bliss.
Sandra rose. Like so often when she got a massage she became a little aroused. And when her luxurious body needed something, there wasn't long from thought to action.
"See you later." She wrapped a towel around her body as she talked to her two friends.
"Come boy." A short demand and she was on her way to new sexual delights followed by her obedient slave.
Shortly after also Diana took direction to her room for more private activities. Her slave husband followed her as a humble dog. He had important service to deliver.
Nicole was then alone at the terrace with her slave massaging her body.
"Well, it seems it’s time for some private fun. And don't worry; you will not be cheated for the goodies. Follow me, boy."
Soon there was absolutely quiet at the house. Not totally quiet. The carefully listener would from three rooms observe small moans and heavier breathing, and if someone had peeked through the keyholes, they would have seen a naked man kneeling in front of a bed and with his head buried between a woman's legs, who was lying on the bed..........
.................When the paper and pencils were divided, the three women sent each other smiling eyes before they put a number at the paper.
The slaves were on needles. Their destiny was in the hand of each woman and soon they would know it.
In turn each woman showed her score to the others. There came small gasps from the slaves as they caught glimpses of the numbers.
When all numbers had been shown the three women roared in laughter and the slaves sighed of relief. They had all scored a 5. No doubt that each woman last night had received an expert tongue service.
"I think we have succeeded with our motivation." Nicole laughed.
"Yeah, they must have been desperately to deliver." Sandra was one big smile.
