David appeared at the entrance to the library and caught the attention of Mac and Master G, who rose and walked over to him.
"How is Stephanie?" Mac asked. He was worried that he might have pushed her too far.
David looked at him for a time, his face betraying no expression, keeping his friend in suspense. Finally he took pity and smiled.
"She will be fine once she's had time to relax and recover," he said.
Mac breathed a sigh of relief.
"Are you two ready for the final test? David asked.
"Oh yes!" they replied fervently.
The events of the evening had left them both highly aroused and this final test was at last going to give them the release they needed.
"Remember," David cautioned them, "we are going to have to maintain ourselves under strict control. This is not something that Stephanie has undergone and we have to make sure we do not give in to our desires. This evening is ultimately for her benefit, encouraging her growth, refining and enhancing her body's natural instincts, helping her reach her full potential. All of that could be at risk if we are not extremely careful!"
The two Masters nodded earnestly. All week David had been explaining how special this particular sub was and how high he had set his sights for her. They were very well aware of what was riding on this last test.
"Very well," David said.
Stepping further into the room, he addressed Sue and Mistress C.
"Ladies, please excuse us while we prepare for the final test," he said. "I would be obliged if you would see that Master G's sub is kept company until his return."
The two ladies nodded their acquiescence and the three men left the library to return to the display room.
Once there they removed the trolley from the dais, putting it back in its place. Next David pressed a button and a track whirred to life. Out of the shadows came a metallic chinking and slowly the source of that sound came into view. Suspended from a substantial hook in the track system was a horizontal, hollow square, metal frame. Thick chains hung down from each corner. Suspended between these chains was a thick, webbed, black leather sling. There was an assortment of attachments dotted around the outside of the sling. There was a further chain hanging down in the centre of the frame, slightly shorter in length than the others.
Once the apparatus was in position above the centre of the dais, David lowered it to the floor. Mac, in the meantime, had made his way to the drawers and was selecting a number of items, which he laid out on a small trolley. He wheeled this back to the stage and Master G helped him lift it into place.
David went to the back of the room and exited through the door that Kristy and Bobby had used earlier. It led to a room that was used specifically to clean and sterilize equipment. He opened a cupboard door and brought out a metal bowl, placing it in the sink. He took a liquid cleanser and poured a liberal amount into the bottom of the bowl. The cleanser was a combination of an astringent, antiseptic, and liquid soap. Next he ran water until it reached the temperature he wanted and then filled the bowl. He removed a matching lid from the cupboard and fitted it over the top of the bowl. The lid would keep the water at the desired temperature until needed. He carried the bowl over to a trolley and then opened another cupboard and removed a pair of dark red, fluffy hand towels. He placed them beside the bowl and then wheeled the trolley out to the dais. This time it was Mac who assisted in lifting it into place.
With the equipment ready, the men each withdrew a cock ring from their robe pocket and secured it around the base of their shaft. They had no intention of cumming too soon! They rearranged their robes and returned to the library.
"Kristy, bring the sub to the display room," David commanded.
Kristy rose and gracefully left the room in compliance.
David gestured towards the door.
"Shall we?" he asked his guests.
They were more than happy to oblige and made their way back to their seats in the display room. This time they were seated before Stephanie made her entrance, eyes dutifully lowered as befit a good sub. She was therefore unaware of what was waiting for her on the dais until the last minute.
"Position 1!" David commanded and Stephanie swiftly stood with her feet widely spaced, her hands behind her head.
"Mistress S, may I have the use of your sub?" he asked Sue formally.
"Of course, Master D," she replied with equal formality.
David beckoned for Kristy to step onto the stage then turned and addressed the guests.
"For this last task the sub must be carefully prepared" he said. I have asked Mistress S if her sub will do this for us and she has agreed.
He quietly explained what he wanted to Kristy. She was slightly shocked at first but knew better than to show any sign in front of others. She therefore walked over to Stephanie and stood behind her.
"Brace yourself," she muttered to the girl, her lips hardly moving. "Remember your training!"
Stephanie didn't have much time to wonder about the meaning of the words as she felt Kristy's hands unlacing her corset. She suddenly realised what her friend had meant. She was to be undressed in front of everyone. She trembled slightly. While she had become used to being naked in front of her Master, she was not sure how she felt about being so in front of several people. Nevertheless, she was determined not to disappoint her Master. She took a deep breath and steeled herself for what was to come.
By now Kristy had loosened the corset and released the stockings from the suspenders at the back. She now moved to the front and released the suspenders there, giving Stephanie a glance of sympathy as she did so. She wasn't sure if the girl noticed as she had a look in her eyes that showed her focus was directed inward.
Slowly, making it as much of an art as possible, she rolled the stockings down to the tops of Stephanie's boots, which she unlaced and removed.
David walked forward and unlocked the cuffs circling her wrists and ankles, removing them and placing them on one of the trolleys.
Now Stephanie was standing at the front of the dais, her naked body bathed in the circle of bright light. Part of her, the 'old' Stephanie, longed to cover herself up. The 'new"'Stephanie, however, was proud of who she had become and secure in her Master's faith in her. She therefore kept her eyes down but stood tall, elbows pulled back so that her breasts were thrust out in front of her, pelvis tilted and legs spread wide.
She couldn't see how proud David was of her but everyone else could.
Next, Kristy removed the lid from the bowl and soaked the first hand towel in the hot water. She proceeded to thoroughly wash the perspiration from Stephanie's body, making sure to clean thoroughly between her legs. She rinsed the towel before dipping it inside the young woman's pussy making sure it too was cleansed. Finally she once again rinsed the towel before moving behind Stephanie and thoroughly cleaning around and inside her back passage.
By this time Stephanie had almost forgotten that she was naked in front of several people. Despite the intensive nature of the evening, or perhaps even because of it, Kristy's touch was once again stirring her body's natural instincts. What she didn't realise was that David had been carefully training her body and mind to be ultra-responsive to the slightest, intimate touch.
Kristy switched the wet towel for the dry one and proceeded to give Stephanie a vigorous rub down, which left her skin pink and glowing. David nodded his approval and helped her remove the trolley from the dais. Kristy swiftly wheeled the trolley back into the annex before returning to kneel at her Mistress' side.
Now it was David's turn to move to the edge of the room and open a special cupboard. He withdrew several items from inside then returned to the stage.
"Mistress S and Mistress C, may I have the use of your subs?" he requested.
"Certainly," they replied, gesturing to both their subs that they should move onto the stage.
