David turned to Stephanie. "For the remainder of this evening you are to obey each Master and Mistress completely and without reservation," he told her. "I expect you to do everything that is demanded of you to your fullest ability. Only by doing so will you stand a chance of passing this test! Do you understand?)"
Stephanie nodded, maintaining her eyes dutifully lowered.
Now David turned and addressed Master G.
"Would you like to start off Stephanie's testing this evening?" he asked.
"It would be my pleasure!" Master G replied.
He moved to the chest of drawers and removed a number of items, which he placed in his pockets before returning to stand on the dais.
"Position 2" he commanded and Stephanie dutifully sank to her knees, keeping her hands behind her head as she did so.
Master G looked down sternly at her. "You will demonstrate your oral abilities, sub. Begin!" he commanded, as he parted his robe.
Stephanie breathed a sigh of relief. At least the test was starting with something that she was confident that she excelled at. With determination she leant towards Master G, gently taking his flaccid cock in her hands. Slowly, with the lightness of a feather, she traced a line from the base of his balls up to the tip of his staff and back down again. Over and over she repeated her actions, maintaining that feather light touch and was rewarded as Master G's cock first stirred and then gradually swelled.
Master G took a deep breath and firmly set his mind to resist her ministrations. David was right, this girl was exceptional when it came to oral!
On the next pass, Stephanie's hands slipped lower and delicately cupped his balls. She used a nail and dragged it lightly across the surface of each before locating the vein that ran between them and tracing that too with her nail.
Above her, Master G had to suppress a quiver of desire that threatened to betray to the sub how successfully her technique was working. It would not do to let her become complacent at this early stage of the proceedings!
She ran her nail lightly over the length of his shaft, up and down, returning to caress his balls before once again repeating her actions.
Master G lifted his eyes to David's and they shared an intense look that Stephanie missed, so intent was she on her task. In it they conveyed their agreement that this young woman was indeed something special and with the right guidance would reach the stars.
Master G was brought back to his immediate situation as Stephanie now replaced her finger nail with her tongue, tracing a delicate track up and down his shaft, circling his balls before once again repeating her actions. Again and again her tongue laved his shaft and balls, varying in its pressure, sometimes light as a feather, sometimes strong and demanding.
Master G could feel a faint tremor start in his thighs and groin and knew he was going to have to do something soon or the test would be over far too quickly. Just as those thoughts ran through his mind, he felt Stephanie's tongue swirl around his glans, licking, flicking, teasing before dipping into its centre where pre-cum was already starting to glisten.
"Cease!" he commanded and Stephanie dutifully but somewhat reluctantly obeyed. She had been so intent on what she was doing that the rest of the room had faded out of existence. Her pussy was hot, wet and throbbing.
Master G beckoned to David and when he ascended the dais murmured something in his ear. David nodded his agreement and moved to where the drawers stood. He removed several items and a leather strap before returning to hand them over to Master G. Stephanie remained in Position 2, eyes dutifully downcast and therefore unable to see that while David had been at the drawers, Master G had withdrawn a cock ring and settled it deeply at the base of his now fully erect staff.
"Position 3!" he barked and Stephanie swiftly complied, placing her head on the floor whilst her hands reached behind her and spread her ass cheeks wide. Over the past several days she had been drilled unmercifully in each of the positions until they were now second nature and she no longer even thought about them, it was just instinct.
Master G reached between her legs, pleased to find her pussy dripping wet. He took the large vibrator that David had given him and slowly, carefully eased it into her passage. Stephanie had to suppress a moan as she felt herself being filled to capacity. Next Master G took a bottle of lubricant and started to liberally work it around and into the sub's anal passage. When he was sure that she was well lubricated he took a butt plug and slowly eased it into her. (David had briefed him fully on her former inhibitions regarding anal penetration and was determined not to set back her training by carelessness).
Finally he commanded Stephanie to assume Position 1. She rose gracefully to her feet, hands behind her head. Master G took the leather strap and attached it to a concealed hook at the front of Stephanie's corset, letting it drop down to hang in front of her legs. He then moved behind her and drew the strap between her legs before securing it to another concealed hook at the back of her corset. The result was that the vibrator and butt plug were pushed even further into place and the concealed clitoral vibrator was held right up against Stephanie's clit.
