There is an untold truth about swimming pools, especially ones frequented by curious children. Untold, because of the image the truth elicits regarding bodily fluids and the water that you are swimming in. Also untold because of the awkward nature of the subject - masturbation. After saving their money for a year, slaves aaron and maryanne had installed their lovely swimming pool. Soon after, they themselves learned this untold truth as they soon learned the process of avoiding looking at exactly what it was that their son and daughter did (individually, not together!) when they jumped into the crystal clear water, and then swam directly over to one of the two water-jets at the end of the pool.
But, on this occasion, all eyes were on the twins as they both rather awkwardly held their position in front of the fast-flowing water, keeping the pressure right where it felt best, whilst their parents and Master and Mistress watched on from the steps of the pool. Before starting Master had given his youngest slave a lecturer on the dangers of blasting her privates with jets of water, however once he was satisfied that she understood, he told both of the twins that the last one to orgasm would receive a reward. Skinny dipping in the pool wasn't entirely new to the teens. They had occasionally played truth or dare with their friends when their parents weren't home leading to some naked pool time, but the fact that they had both learned to masturbate using the water-jets was not something they ever expected to admit to someone, nor to demonstrate the activity in front of their parents.
Glancing to her side, sandy saw her brother enjoying the flow of the water. As she found herself feeling rather awkward instead of sexy, she began considering the idea of faking an orgasm just to beat her brother. Before that idea could chrysalis, both Master and Mistress glided through the water and took up positions behind the twins, moving their hands over their young bodies under the water. The slaves enjoyed the new sensations of having someone touching them as they did something that had til then always been private. When Mistress' fingers played with the flow against slave sandy's clit, she found herself rolling her hip under the water to try to better the sensation it was causing her body. When Master pressed his fingers under slave steven's balls, the teen found himself pressing back against his Master's body as the sensation both stimulated his perineum and tightened the skin on his cock, making the blast of water better pleasure him.
Seeing sandy's body tense just a matter of feet from him made steven excited, knowing she was having yet another orgasm in his presence, but also wondering what his reward was going to be. Trembling in the water sandy let out a long moan, then tried to move herself away from the stream of water that was pounding her clit, only to find Mistress' body pressing her back up against the jet. The teen brother watched on, wondering if Mistress was punishing his sister for not begging permission to have her orgasm.
"Count, slave. Count to ten." Mistress said in sandy's ear over the noise of her moans and the water.
All sandy could muster was a guttural whimper as the orgasm from the pressure on her clit continued.
"Count!"
"One, two, three - please i - i " she managed between splutters, her hands writhing on the side of the pool.
"Slower."
After crying out again she restarted. "One... two..."
"Mm," Mistress pondered, interrupting her. "How about, in French."
The slave girl lowered her head in frustration as her pussy became more and more sensitive as her orgasm was now reaching over one minute in duration.
"Un, deux, quat - oh fuck! - trois, quatre, cinq..." sandy struggled through her French, never having imagined such a need for the language of love.
Smiling over her shoulder, Mistress reached between sandy's legs and used her fingers to better expose the girl's clitoris to the insistent flood of water.
"Sex sept huit neuf dix!" sandy hurriedly finished, and was relieved when Mistress pulled her away from the water-jet and into her arms, clinging to her tight as she tried to regain her breath. As she held the girl, she kissed her on the mouth, calling her a good little slave.
Master's hand had found its way around slave steven's cock during sandy's French lesson, but now he simply used the teen's cock to guide him to the steps.
Still holding the boy's cock with one hand, Master pulled slave aaron's face to his, and kissed his lips passionately. Master whispered, "you should be proud." Then turning to sandy, he added, "I have a task for you, slave girl. I've allowed your father's cock to be out of its cage for far too long now. I want you to take your father and put his cage back on. Take some ice and a towel like I showed you before. If needed, I'm sure slave aaron can give you some pointers. First however, you are to take him in the shower. Make sure he is nice and clean. Do you understand, slave?"
Realizing the importance of having her Master trust her to perform such a task, sandy nodded her head.
"Do you have any questions, slave?"
For a moment sandy thought about the experience of taking the cage off, and putting it back on. Getting the first ring over her father's balls had seemed the hardest part. "What if i can't get the first ring on, Master," she asked.
"Try a little more ice, slave. I have faith in you. Go now."
Sitting on the step, slave maryanne watched her daughter as she boldly followed Master's lead and grabbed her father playfully by his rather shrunken wet cock and lead him out of the pool and into the house, walking gingerly once through the glass doors so as to not slip on the tiles inside. A small knot formed in her stomach as she wondered whether Master was going to hand her husband's chastity key duties from herself to her daughter.
As the more adult adults exchanged a few glances and passing comments about the warm water and hardened nipples, slave steven waited awkwardly with his cock still in Master's hand, wondering what his reward was going to be.
