Preparation

As the car passed by the familiar city buildings Ava came to a momentous decision. This meeting would obviously change everything for her future. For her compliance to Lorenzo's will. The start of a whole new life path, leading her towards becoming a true slave for her one chosen master, if she agreed to the conditions he gave her, of course.

Being honest with herself, this is what Ava believed she needed, in fact had to have. Something she considered her whole being passionately desired more than anything else she had ever wanted in her life. It was all about lifelong commitment and mental wellbeing, as well as all of the sexual pleasure and subtle pain that went with it.

She wondered if this was about demanding her be his slave, then asking her to marry him too? The idea filled her with exotic pleasure. As his future wife, she would do exactly what he wanted, his slave, with no questions asked. If he wanted to bend her will to his then so be it, or just bend her over a desk, flip up her skirt and take her, so much the better. Yes, she really did love Lorenzo.

The taxi ride was short, dropping her off at a new downtown city skyscraper, one she didn't recognise. It looked like the building had just been completed, ready for its first occupants. Yet another new downtown commercial office she guessed, all sweeping steel pillars and smoked glass.

The vast atrium, cloaked in white marble, had a slight chemical smell from the new carpets and dark-painted décor. There was no furniture as yet apart from a long black marble table, resting against a deep red wall at the back of the entrance. There, lying on top of it was an envelope with her name on it, in Lorenzo's writing.

She opened and unfolded the two-page letter, reading it carefully several times. It contained her instructions. She guessed this was why he wanted her there early, to take in what he wanted and to and understand what he expected of her from now on. Apart from what she had been instructed to do next there were lots more listed instructions that she was to learn, information she would need for her future life with Lorenzo. She was to take the lift, enter the office and stand and face the chair, then wait for him. She was also to keep her face downwards and not to look into his eyes at any point during the day, or she would be strictly punished.

She did what she had been told and took the far lift to the top floor of the building. Rapid and almost silent as it sped its way up to the thirtieth floor, Ava was nervous once again with the expectation of it all. As the lift doors opened, she saw a large glass double-panel door with long chrome handles in front of her. She pushed gently on one of the handles, expecting the door to be heavy, but it hinged open almost effortlessly.

Inside was a vast office with a soft and luxurious aqua-coloured carpet. Inside was the large black chair she had been told to stand by. Ava looked around. Apart from a large black chair, positioned in the middle of the room, the only other furniture was a small table and a tall freestanding mirror placed slightly off to one side.

Nervously she positioned herself in front of the chair and stood still, hands folded behind her back as instructed, waiting. Minutes passed as Ava stood there, fizzing with excitement, calves straining in the high heels.

Ten minutes later Lorenzo entered. He studiously ignored her, exactly as he had during her first full experience of BDSM with him. He stated at the outset that in control here. Pausing only to remove his jacket, slinging it casually over the back of the chair, he sat down directly in front of her, the big black leather armchair adjusting to his weight with ease. He studied her approvingly, looking her up and down, smiling at her compliant nakedness.

She looked well away from his critical gaze, moving her view of the world down, as he had instructed her. As her eyes lowered, she began to blush, not just from the lack of underwear but suddenly realising why he'd chosen the slinky orange velour skirt for her to wear to the meeting. In getting to the top floor the tactile material had stuck slightly to her skin with each long stride, riding higher up her thighs with each step. The tight hem was now way above her black stocking tops and Ava could sense that was exactly where he was looking, right now.

Without panties on Ava knew that everything she possessed as a woman was now lewdly and provocatively out on display for him. Her legs began to shake slightly as he stared at her fully exposed vagina. She could only guess what he was about to demand of her, or do to her, in the next few hours.

He got up from the chair, removing his tie and gold cufflinks slowly. He gazed back at her breasts, rising and falling rapidly, following the fast rhythm of her staccato breaths. Lorenzo took off his shirt and then his suit trousers, folding them neatly and placing them all on the table by the side of the chair. Ava realised the long mirror off to the side, just behind her was so he could see a 360 of her luscious body, without moving from the chair.

Naked now, apart from his striped boxers, he sat back down again casually. Lorenzo tilted the black chair forward slightly, positioning it to offer instant access to every intimate part of Ava's soft body, just an arm's length away from his comfortable seat. She was startled when he finally spoke.

"That's very good, Ava. You were on time and wore what I asked. That's a great start."

Taking advantage of her obedient immobility he leant forward slightly, running his open hand up her leg slowly, stopping at her stocking tops.

"Black hold-up stockings too, very classy. And that will certainly make things easier for me."

Ava opened her mouth in surprise as he continued, his hand slowly stroking her thigh, moving higher and higher towards her lips. She could feel she was starting to moisten up once more. She tensed her legs, drawing in a sharp breath as his hand glided over her skin, felt the goose bumps on the top of her thighs Ava had no idea what was to come, hoping it was going to be her eventually, but guessing that only when he truly wished it to happen.

"It's worth explaining why I put the 'no panties' rule on the note Ava. It's for one reason only. To provide me with easy, fast and unrestricted access to both of your beautiful orifices, your vagina and anus."

No longer covered by the short orange skirt, both delicious parts of her anatomy were now directly in his eye-line, from the front in his direct gaze and, reflected in the mirror, her soft rounded rear. Ava's breasts rose and fell, her breathing increasing in pace as he stared deep and hard over all of her, his deep concentrated gaze strolling casually up and down her long body.

Sensing a movement, she glanced down into his lap, his own dominant needs becoming visible, the hard swelling of his growing penis tented up his crisp white briefs. She looked up again quickly at him to see what he was thinking, forgetting, the clear instructions he'd insisted on as her master, never to look in his eyes directly, unless he told her to.

He saw her look at him and decided punishment would come later. He got out of the chair, moving over to the long vertical mirror, adjusting its angle slightly. His hard penis pointed accusingly at her, directly in line with her rapidly moistening vagina.

"Come over here, Ava. By the mirror, stand in front of me."

She walked over slowly, head down, buttocks and pubis on full display, facing him. The submissive demeanour she had chosen clearly gave itself away. Ava stared at the floor, her breathing becoming fast and ragged in expectation of what was to come. Her breasts swelled gently inside the tight black satin top, white pearl buttons looking like they were going to burst in places.

Ava stood there, stock-still, waiting, silent. He moved quickly and she winced as he neared her, but kept staring down at the floor, as instructed. She also knew to stay silent unless she was asked a direct question by Lorenzo, her master-to-be.

"That's what I like to see Ava, obedience. Very different to when we last met. I'm glad you have decided to change and have seen the error of your previous wilful ways."

Lorenzo turned again to see the reflection of Ava's beautiful bum in the long mirror, honed and toned to perfection. He pulled up the short skirt further at the back.

"Much better, Ava. The skirt's very slutty but that's much to my liking, I have to say."

In her deep cunt cleft, he began to see the signs of glistening moisture. A thin white line of light creamy juice began to descend one of Ava's taut, tanned thighs, the flow increasing steadily, second by second.

"Good to see that you're prepared and ready for me too, Ava. But I'd like to see you finger yourself for me first. Remember your instructions in my letter. You are not allowed to orgasm at any time until I specifically say you can. If you disobey me, you will be punished."

Her whole body shaking slightly, she was glad his first instruction as her master was easy. She glided her left hand down her skirt, lifting the hem up to reveal her soft tanned pubis. Inserting a manicured finger from her right hand delicately inside, Ava slowly stroked along the length of her pussy crease, giving herself an electric start each time she touched her swelling clit with her long fingernail.

Lorenzo watched her rub inside her inner lips, first pushing one and then, increasingly, two fingers inside herself, her body responding rapidly to her frantic ministrations. As she bent forward and played with herself, Lorenzo could see she was getting just a little too enthusiastic at this initial task her had given her.

"That's enough, Ava. I told you not to even think of coming without my permission. You should know you have disappointed me already."

Ava paused, shocked. She stood upright, hands held by her sides. What had she done to displease him? She had got so close to orgasm too, it was so frustrating.

Entranced, Lorenzo watched a long white strand of pussy-goo slowly drip from one of Ava's sticky fingers onto the soft carpet. He handed her a small towel.

"Clean yourself up, you disobedient slut."

He watched intently as she wiped over her fingers, passing the towel down briefly, padding the soft material at her lips to dry some of the juices between her legs.

"It's my turn now. Take off your top and skirt. Put them over there, on the table."

Still shaking from having almost reached orgasm, Ava pulled the top out from the tight skirt. Starting from the bottom she undid the pearl buttons on the black satin top, one by one. She could see tiny smears left on the back fabric from the remnants of the juices still on her fingers, as she freed each button. Reaching the remaining two buttons Lorenzo watched the fabric tighten perceptively, straining hard over her tight breasts.

"Undo the last two buttons slowly Ava, lentement."

Pausing, Ava wondered why he'd suddenly dropped into French Canadian, receiving a hard slap on her inner thigh for not moving fast enough. She gasped with the sudden sharp pain. It was her first slave punishment, and she wondered if there were more to come.

Gripping the upper of the two remaining buttons she popped it out of the hole. Her globular breasts were instantly freed, spilling over the top, the remaining button just holding. Her breasts sat, rocking forward gently atop a balcony of black satin.

Lorenzo leaned in, knowing what to do. He pulled hard at the satin top and the last button instantly gave way, her mouth wide in surprise, Ava glanced at him again as her globular breasts swung free, bobbing gently from side to side. Lorenzo smiled wickedly, grasping her nipples hard, twisting them, knowing she had looked at him once more. Ava yelped.

"Lovely. Now the skirt, Ava. Take it off. Do it quickly."

Shaking, her swollen nipples still smarting, Ava struggled with the zip on the tight skirt, but it was jammed up on the orange fabric. She tried jerking the zip up and down, but it wouldn't budge.

"For god's sake, Ava, can't you do one simple thing that I ask of you?"

She flinched as he moved forward, grabbing the skirt at the waistline, ripping it off her body forcefully. Shredded from top to bottom, the wrecked garment fell at Ava's feet. Apart from her high heels and stockings, she was now completely naked.

"That's much better. Now come here, back to the chair."

Lorenzo settled himself into the comfortable seat as Ava walked back in front of him once more. A clear instruction in the letter she'd read on the ground floor was that now, whenever she was naked in his presence, she should adopt a power stance. Ava remembered the diagram in the note, shuffling her feet apart, long legs spread wide. Her thighs straining, her vagina was spread wide for him. Inches away, her lips open, Ava's clitoris began to peek out through her neat fleshy folds.

"Come even closer, Ava. Stand by me here, next to the chair."

As she moved forward, he seized both of her hands quickly, whipping her around roughly in her high heels, all in one swift motion.

She gasped and tipped sideways, overbalancing, falling backwards into his chest. He put his hand underneath her quickly, grabbing a soft naked breast, using the mammary to lever her back upright. She tottered as he held her there, still gripping her globe painfully in one hand, two fingers on either side of a hardening nipple. He suddenly released her. Her calves and thighs strained to balance herself in the six-inch heels. She saw deep red lines from his nails across the delicate flesh of her left breast.

Grasping her hard by muscled bum cheek, Lorenzo pulled Ava closer into him. She squeaked. Bending her at the waist, he pulled her into his lap, pressing her pussy down over his briefs, where his penis was beginning to harden again.

He reached into a small cabinet by the side of the chair, taking out two black cuffs with robust D-rings. There was an interesting assortment of other items in there too, but he had yet to decide if he would use them on her. Maybe later, after lunch.

Lorenzo pulled her hands behind her back then buckled the padded cuffs tightly around her wrists, connecting them together with a steel clip. He pulled her further over his lap. As she moved forward, he was pleased to see a dark imprint of her wet cunt lips on the front of his white briefs, like a damp sideways kiss.

He smiled. So, the slave had inadvertently marked her master, had she? She would pay for that. He was picturing the future marking session, Ava bound tightly over a sturdy table, ready to have his initials tattooed into her delicate soft flesh near her vulva.

He pulled her further forward over his lap, her head resting low on the soft carpet.

"Bend your legs up at the knees, Ava."

She almost fell forward but he held her steady, her feet near his face as he attached black leather gaiter cuffs with similar D-rings around each ankle.

"Now get up, Ava."

She struggled to her feet, her hands behind her back making both movement and balance very difficult. As she rose unsteadily, obscured from her view by his seat he brought out a black rod from behind the chair. It was a long-leg spreader bar.

As Ava stood up, he leaned forward in the seat, putting the rod on the floor and clipping one of the D-rings on her ankle strap to the end of the rod. He made her shuffle her feet sideways until the ring on the opposite end was in line with the D-ring on the other ankle. He leant forward and clipped the second D-ring to the spreader bar.

He got up out of the chair, pulling her shoulders forward, walking behind her. Her legs were spread wide by the four-foot-long bar, reducing her waist height by three inches. He'd worked it out, basic triangulation maths invented by the Greeks. Six-inch heels minus three inches in height meant she was exactly the right height for him to penetrate her pussy with ease.

Ava's eyes looked quizzical, spotting he took something small out of the cabinet. He held it out for her to see. Ava's eyes went wide. It was a steel rubber-tipped clamp. He grasped her left breast, fixing the tiny teeth over her nipple. As the pincer bit into her delicate flesh, Ava cried out in intense pain. Lorenzo used the distraction of this initial agony to attach the second clamp to her right breast.

Reaching back into the small cabinet of sexual delights he pulled out two objects, short thin chains with a lead ball at the end of each. Using the small clip rings, he attached a chain and ball to each clamp that was jerking up and down on Ava's heaving breasts as she fought to keep control of the pain searing through her nipples.

Ava stood there, shoulders shaking, the clamps and weights dangling obscenely from her tender breasts. Lorenzo added a small chain, clipping it between her nipples so it hung in a catenary. He experimented a little, flexing his fingertips along the chain, watching Ava's expressions and grimaces as he applied more pressure, as the clamps bit harder into her tender breasts.

Lorenzo turned her around, suddenly slapping her buttocks hard with the flat of his hand. Ava screamed.

"Remember I said that disobeying my instructions would result in punishment, Ava? So far, you've looked directly at me twice and I've heard four sounds from you. All these transgressions will result in a suitable punishment."

About to blurt out that the only sounds from her were responses to his smacks, Ava stopped herself, biting her tongue. She stayed silent. She glared to one side, remembering not to look at him. Pain seared across her buttocks, but the desire not to be punished again quickly overriding her anger.

Lorenzo put one hand under her bum and the other on the handy tit-leash, pulling her and making her move across the carpeted floor, her hips swaying from side to side as she tried to move with the long spreader bar.

Oblivious to her fury, Lorenzo pulled her forward, keeping a close eye on the chain and steel-jawed clips to make sure they stayed in place. Even though the nipple clamps were really hurting, Ava was getting really turned on now. All of this pain and punishment was making her so frustrated, and yet it was also giving her subconscious the dominance it craved too.

After making her walk a few yards, to get her used to the bar, he brought her back, sitting down in the chair a dozen feet away. He then motioned for her to come over to him. Ava shuffled forward awkwardly and slightly fearfully. It was incredibly difficult not to overbalance in her six-inch heels, the long wooden black spreader bar tightly strapped to her ankles, forcing her high-heeled feet wide apart. Shackled behind her, she realised how important her hands were for balance too and at how much risk she was at from toppling sideways.

With her feet hobbled she had no choice but to carefully waddle back to him, as quickly as she could. With every step the lead balls attached to her nipples swung sideways, the pain in her nipples stinging like wasps. As she got close, he reached out, pulling her in close to his chair by the chain dangling between her breasts.

He positioned her directly in front of him. She watched, expectant, as he released his heavy penis from his briefs. It sprang to attention, but he further hardened himself up, pumping his purple shaft with a few swift strokes.

"Now Ava, I'm sure you understand I am not going to waste my time with you as my slave if you are not of the right calibre. I think therefore we need to inspect you properly. Now."

She was shocked at his tone, and its submissive implications.

With one hand still stroking his cock, he thrust his other forward to tease her ripe labia lips apart with the round tip of his forefinger. It was of little surprise when he removed it to see the effect the recent bondage attachments and devices had induced. His finger was wet, sticky and slick, covered in her creamy cunt juices.

"Remember Ava, whatever I do to you, you cannot come without my permission."

He teased her inner labia mercilessly, slipping both his ring finger and forefinger deep inside her, simultaneously rubbing the head of her clitoris gently with the tip of his thumb. This was what she had craved. Ava began to seep hot sticky fluid around his fingers. Lorenzo saw a dribble of liquid slip down her thigh, emerging from between her soft lips.

As he pushed two long fingers more fully into the depths of her warm cunt, he watched her knees flexing ever so slightly. She gasped at this deeper intrusion, at being penetrated so brusquely. Withdrawing the two fingers, he looked up to see her expression, but Ava's eyes were now firmly closed, partly so not to risk staring back at him, but also savouring the moment, clearly close to orgasm.

Deciding she needed to understand obedience that bit more, he smacked the palm of his hand up into her cunt lips. Ava shrieked. Feeling a little guilty, he reached behind her, releasing both of the wrist clips binding her hands behind her so she was able to rub her swiftly reddening labia lips. She stared submissively at the floor as he spoke, her hands by her sides.

"Now Ava, pay attention. Your training as my slave will begin. Remember you are to do what pleases me sexually. This may, in turn, satisfy your own needs but, as your master, that is not really my concern. You are here to do exactly as I tell you. And I mean exactly."

Ava moaned quietly at his strict tone of voice. She hated the fact that this was so often what her subconscious craved, even when she was alone at home. Lorenzo controlling her sexually, dominating her completely. Telling her what to do and how to do it, all in intimate detail.

"I'm sorry Ava, but there's no resting. I have a lot planned for you this afternoon. But what we're going to do now is something we've not tried before. Turn round and sit in this black chair. Sit with your legs spread and open yourself up, while I prepare something really special for you."

Ava complied, being careful not to overbalance as she hobbled in her heels, the long spreader bar tethering her ankles tightly. She turned and sat down quickly, the warm leather and her hot juices rapidly making the seat slick and slippery. She spread her knees wide, using her slim fingers to pull aside her delicate inner labia, spreading her wet vagina wide open, for him to view.

He watched her, enraptured. Then he wheeled the tall mirror over, positioning it so she could see herself, see her soft pink insides and the light, white layer of creamy juice she was exuding so much of, in expectation of sexual activity to come.

He turned his back to her, making sure she couldn't see what he was doing. From the cabinet he took out a long stainless steel device. He lubricated it with a water-based cream, hiding the cold shining metal object from Ava's view until the very last minute.

He had also decided to put on a blue surgeon's mask for added effect. He walked backwards, then turned round quickly, facing Ava, seeing her with her legs spread far apart, her pussy wide open and fully exposed.

She gasped when she saw his mask and what was in his hand, its obvious purpose dawning on her. Her hands began to shake violently. It was the one thing most women had experienced, and yet very often hated. It was a medical speculum, designed for a doctor to undertake an intimate gynaecological examination.

He leant over her, squeezing her shaven pussy pouch, then making her pull her own inner labia even further apart. He took care to push in the large speculum between Ava's labia lips very gently. Despite its size, the device initially met with almost no resistance, slipping inside her sopping vagina.

He watched her expression as he turned the small screw, to widen the tool out. Normally a doctor would enlarge it out just sufficiently to see a woman's cervix, or to take a smear. But this was a much larger version than doctors had in their examination rooms, opening up far wider in four directions rather than two. It was designed for delicate vaginal surgery, but usually only after the female patient had been fully anaesthetised.

There was no such luxury for Ava, as Lorenzo began turning the screw slowly, opening out the medical speculum to its maximum width, almost twenty centimetres in circumference. Ava whimpered, her eyes wide, face pink, as her vagina was stretched open further and further, wide open to his gaze.

Lorenzo peered down the barrel of the steel speculum, inserting a long finger, making her jump in shock as he stroked the delicate walls of her vagina that were now so accessible. He examined her urethra too, inserting a slim black plastic rod carefully, right in through the small, tight entrance. She gasped, suddenly feeling the need to pee. He removed it slowly and then with another thinner rod, he probed her cervix. Ava jumped in shock. Ava was acutely embarrassed at the unexpected medical examination.

Lorenzo leaned back, seemingly satisfied.

"Now I've seen exactly what you're made of, so to speak, Ava. It looks like you have everything that I need as a future slave."

He wound the screw thread back down on the speculum. It made a sucking sound as he quickly withdrew it, putting the sopping device back on the table. It was time to play with her just a little more.

He returned to the cabinet, returning with what looked like a suction cup with a rubber tube and bulb attached. How many other sexual torture devices did he have at his disposal, Ava wondered?

Leaning forward, he placed the three-inch diameter rubber ring with its clear plastic device directly over her outer labia. It had a long tube with a rubber bulb and a small air non-return valve at the top.

Using her own lubrication to ensure a good seal, he began to pump the red rubber ball. Ava immediately sensed a strong pressure building all around her groin, as Lorenzo began to create a vacuum around her labia lips and inside her vagina.

Unable to look at Lorenzo she couldn't help but stare at herself in the long mirror, watching her inner lips being forced wide open and upwards, as the reduced air pressure in the dome began to gently pull her soft insides out of her body. Ava stared, transfixed and not a little worried. Would it turn her inside out?

She felt the intense pressure all around her vulva, her labia pulled by the unseen force up into the clear dome. Unlike the speculum, it was a highly strange but actually not unpleasurable sensation. The feeling of your outer labia lips being sucked apart, tight against the sides of the dome, was strange but erotic too. Ava felt it very odd that all her sexual parts were now out on display to her as well as Lorenzo, perhaps more so than when he had been staring down the steel speculum tube.

Watching her expression, he handed the bulb over to Ava.

"It's your turn now. Show me. Keep on pumping until you feel you can't take it anymore. Just keep going steadily. Take breaks when you need to."

Rather than watch exactly how Lorenzo had been using the strange device, Ava had been watching her labia unfold, fascinated. Now she fumbled with the red bulb, unsure how hard to press it each time. She gave it a few quick pumps, entranced by the sense of control it gave her over her own body. As she gently pumped up her pussy in front of him, she saw him pull down his white briefs and began to stroke himself once more. She watched his penis as she pumped. Her watching him, watching her. She was astounded at how amazingly sexy the feeling of the pumping felt, her whole pubic area engorged with blood as the vacuum pulled her lips wide open, sucking up her inner labia, all pink and incredibly puffy.

Lorenzo watched, entranced. After five minutes Ava's entire pussy had been sucked up almost two inches into the domed device. It looked like an obscene mould filled with deep, dark, pink sex blancmange. He could see Ava had reached her limits, the look of enjoyment on her face beginning to turn to one of concern. He put a hand over her wrist.

"That's enough, Ava. Now, gently release the metal screw on the air pressure bulb. Just turn it anticlockwise slowly. Let me watch as you do it."

Ava did as she was bid, startled at how, when the pressure was released, her shaven pussy seemed to stay up in its domed shape. But she was even more astounded at the sensations she felt all over her groin as the pressure was released. Everything felt hot, sensitive, aroused.

Lorenzo released his cock and bent forward, marvelling at the sight. He'd not used this pussy pump before, only seen it used on videos. Ava's whole pussy area was like a large sexy pink computer mouse, her clitoris the mouse wheel, her upper labia the side controls where you pressed to go forward and back. He decided that was exactly how he was going to handle the sight spread out before him.

The second she saw Lorenzo's hand descend over her pussy, Ava started to ooze. As he touched and prodded the sensitive flesh, she felt herself beginning to come to orgasm. But she held it back, fearful of what Lorenzo had instructed her. He squeezed her obscenely engorged and fleshy inner labia, sending waves of pleasure flashing through her lower body.

"Touch yourself, Ava. Feel what it's like, with your pussy pumped up."

Ava tentatively reached forward, avoiding her swollen half-inch clitoris, lightly touching her engorged labia lips. It was a very strange feeling. The vacuum had pulled so much blood into them and they were so tight, yet slightly rubbery to the touch. She put her palm over herself, barely covering her raised mound. The sensitivity she now had there, in her hand, was a revelation.

"Stand up and come over here, in front of my chair."

She rose with difficulty, leaning forward slowly. She moved unsteadily towards his chair, legs wobbly and feeling nervous, looking down at his waiting hand as he gazed at her. He studied her reactions as he massaged Ava's aching labia lips delicately, sending her into new realms of sensation and delight.

But it was when he started to ping her bulging sensitive clit with his fingernail, then massage the marble sized bud with his fingertip that she almost leapt off the floor. Lorenzo sensed that she was very close to orgasm now, so he leant over to disconnect both the ankle clips from the long spreader bar.

"Time for a more personal examination. How many fingers do you think I should use, and how far should I insert them inside you?"

Ava stood, stunned and shaken at words he'd just uttered. She had never imagined things could move on so fast. After what she'd just gone through in the last half hour, she realised she was getting sore inside. She felt like she'd been with a sex doctor, mortified by Lorenzo's clinical invasion of her most intimate area, with the speculum and pussy pump. Yet thrilled and excited to. Now he wanted to examine her by hand.

She paused. She wanted all this yet knew she would be unprepared for the potential pain of some of his masterful wishes. She stood there for over a minute in front of him, thinking hard. This was also the first time he had permitted her to speak in front of him.

"You may say something, Ava. How many fingers and how far should I insert them?"

After what she'd just gone through, she realised she was pretty sore inside. She felt like she'd been at the doctors, mortified and yet thrilled by Lorenzo's clinical invasion of her most intimate area, with the speculum and then the pussy pump.

Now a hand examination. She guessed he really wanted to fist her. She had seen it online, eyes wide as she struggled to imagine what it must feel like. But it seemed to be enjoyed by both partners in equal measure. Ava knew what he would want her to accept, steeling herself for strange pleasure but potential pain too.

"Master, please insert four of your fingers inside me".

He looked into nervous green eyes, slightly surprised by her rapid reply.

"Are you sure, Ava? That's something I've never done before."

She nodded quickly, preparing herself for what was to happen.

"Ok, but how far should I push my fingers into your vagina? Up to my second finger joint, or further in? Just bear in mind you know how long my fingers are".

"Please insert four of your fingers all of the way into me."

She paused, the pictures and video she'd seen and the videos too. Waiting to see if she could really say the words out loud. She gulped, then spoke in a whisper.

"You may fist me too if you wish. Master."

He looked at her intently, Judging her seriousness and commitment.

"Are you really sure about this, Ava? It may hurt you a lot at first?"

"Yes, master. Your whole hand, all of the way in. Please do it. Fist me."

He nodded then paused to pour a little lube over his hand from a small bottle. He formed his right hand in a peaked shape, palm upwards with his thumb tucked in, watching to make sure she was still OK with what he was about to do. He slowly inserted all of his long fingers into her domed and swollen vagina.

With her already advanced state of arousal, the first two inches slid in easily, making a gentle squelching sound as his hand moved around inside her. He rotated his hand until he had just the tips of four fingers right inside her. He saw her biting her lip, then he then felt her cunt tighten around his fingers like a vice, in panic at what was about to happen. He needed to reassure her about what was about to happen.

"Ava, just relax. This will stretch your vagina, but it won't damage you. You're far more flexible than you think. It may hurt a bit at first, but I'll go slowly. Now, are you sure this is what you want?"

Ava stared straight ahead over his head. Her voice an almost inaudible whisper.

"Yes. My master".

He smiled, twisting his hand gently, watching her reaction closely as he carefully pushed his hand further in. He knew the hard bit would be getting his knuckles past her vaginal opening and that, this first time it would not be a familiar or easy sensation to bear. His hand wasn't small, but the pussy pumping made his task easier, her labia already spread wide apart. He leaned around her, palming her right buttock for support, rotating his fingers steadily, pushing gently further into her vagina.

"That's really good Ava. You're nearly there. Just another half an inch to go."

He knew it was more than that but wanted to make her comfortable with this radical new sensation. He watched her face tense in deep concentration as he pushed. Her face was a mixture of pain and expectation. Time for the last phase. He leant forward and suddenly bit her left breast. Ava cried out but, momentarily distracted, her body responded with a rapidly hardening nipple and a fresh gush of juice into her inner sanctum. Moving steadily, he used the extra lubrication he felt to ease his fingers in, sliding deep into her for this last stage. His hand was now right inside her, up to the knuckles at the junction of his palm.

Ava grimaced in pain, but her expression rapidly turned to surprise as his thumb, until now tucked into the palm, raised up into her wet gap. He pushed upwards, forcing her widely split labia further apart with his thick thumb, resting its tip delicately against her clitoris. He began rubbing her inflated clit, simultaneously massaging her soft, wet, sticky vaginal walls gently and slowly with his fingers, being careful not to cause her swollen mound any more discomfort.

He continued for several minutes. Ava began to whimper slightly, fidgeting on the balls of her feet, to escape from the strong sensations driven by the thrusting motion of his hand and the rubbing of his thumb. His motion made her hips move back and forth as she fought to keep a rapidly nearing orgasm under control.

"Ava, you will remain silent. I also don't need to remind you that you are not to cum without my permission, is that clear?"

Ava nodded meekly. She closed her mouth quickly, firmly, her breathing deepening further into long gushy and deeper breaths.

He massaged her clitoris for another minute, making it hard as a marble, then slowly pulled out his hand. There was a loud slurping sound from Ava's cunt as he slid his hand out, dripping copious vaginal juices. Ava looked embarrassed, happy and elated, all at once. It had felt amazing but really tight and not just a little intimidating, her whole body pivoting over his hand, impaled inside her. He smiled at her again.

"Time for us to go the whole way now Ava. It's a variation of fisting. I have something a little different in mind for you now."

She looked concerned as he turned her round, making her bend forward slightly. She stood like that for almost a minute as he poured more lube all over his right hand. Putting his left arm around her waist to hold her steady, swiftly he formed his fingers back together in a peak and slid the digits of his right hand back into the wet musky dampness between her legs, bending his fingers upwards and moving his hand up and away from him to massage the ridged G-spot at the front wall of her vagina. Steadily he pushed all the fingers of his hand hard up into her virgin arse, using her own fluids to lubricate his way.

As her body rocked back and forth over his hand, he crooked his thumb, pressing it between her plump arse cheeks, finding her anal rosebud within a moment. Ava gave a small squeak of surprise. As he massaged her vagina steadily in a curving motion, his fingers buried deep inside her, he began to press his thumb into her backside. She was tight, but he pushed until his thumb steadily up into her back passage until the joint was past her gripping sphincter muscle and deep inside her anal orifice.

"Ava, I call this the sex glove. I now have all of you, literally, in my hand."

His hands between her legs, he was penetrating her now from both sides, front and back. Lorenzo could feel Ava's fresh juices running down his right wrists in dribbles, where he was thrusting hard up against her extended labia, Ava thrashing her vagina over his extended fingers, rocking her arse over his penetrating thumb.

As he massaged his thumb inside her, slowly and provocatively, Ava's face deepened a broad shade of pink. Her breathing rapidly became more ragged, and she began to pant in time with his finger and thumb thrusts, his hand deep inside her. He knew all he needed to do was provide a little more stimulus and she would be begging for permission to cum, but he wanted her kept on the boil.

He slid his slippery fingers from her pussy, watching the drips of sex juice drip onto the floor as he still held her, impaled on his thumb. He removed his thumb quickly, spinning her round. She almost overbalanced, her mind adrift in the pleasure and pain of it all. He held up his fingers, saw her watching the strings of sticky juice forming like a creamy spider's web between his fingers as he spread them apart. He looked at her then put his hand back into a peak in front of her crimson lips.

"This is what you've created for me, Ava. Suck off all of your juices from my hand. Do it thoroughly".

The words were a shock to her. Even more so when, without waiting for a reply, he slid his four fingers insistently into her pretty mouth. She gagged slightly as he pushed his hand in. But her look told him that her need for arousal through sexual obedience as his submissive sex slave was overriding her conscious disgust at what he was making her do. She attended to the task admirably as he wiggled his fingers.

For Lorenzo, watching Ava's full red lips slide around his fingers, tasting herself on them, feeling her tongue caress them, was an intensely erotic moment. This was something he had dreamed of and longed for, ever since that very first day he had met Ava in the lecture theatre.

He massaged her labia gently with his left hand, watching her expression as she licked his other hand clean, knowing that there would be more excitement with Ava to come.

Far greater challenges lay ahead for Ava with him, her chosen sex master. He had spent the previous evening installing and getting acquainted with a brand new mobile phone app, one which he was going to delight in demonstrating to Ava over the next hour.

Ava was now thoroughly ready for her biggest sexual test of the day. From the cabinet beside his chair, he pulled out the harness he had made especially for her in Italy, based on all her external and intimate internal vital statistics he had studied and memorised.

Ava remembered the first time he had asked to measure her, inserting a number of menacing looking dildos deep into her until she could handle no more of their wide girth, and until they touched her cervix. It had been at the start of their second year at college and she had felt like a patient at the doctors that day. She had watched him write down the numbers in neat handwriting in a small black notebook, her name in block capitals at the head of the page.

He had written L 8.5" (22cm) and G 6.5" (16.5cm). She thought about this and was fascinated to think that she was designed internally to take a broad, fat cock over eight inches long. Much bigger than she thought she could cope with, and way bigger than most of the sexual partners she had experienced had possessed.

Today was to be the first day Ava would experience the 'tempter' as he called it. The custom-made device had a tight Italian leather belt from which hung thin leather straps, attached to two soft black rubber dildos, one considerably larger than the other. The slim waist belt included a snug lock at the front to which the straps fitted tightly, and which could only be opened with the single small key Lorenzo had threaded onto the slim gold chain around his neck.

He slipped the belt around the soft skin of her slim waist, just above her hips and below the waistline of her skirt, held up high. The lock clicked shut, leaving little room for the belt to move. He lifted the strap holding the two heavy dildos, pushing his index finger back briefly inside her hot vagina, scooping out some of her copious juices. He lubricated the smaller five inch dildo with her nectar, pushing it gently but firmly past her tight and still sexually virgin anal ring.

Ava had persistently refused Lorenzo any anal sex, so he had to twist in the dildo slightly as he carefully positioned it up into her bum. Ava's face registered the pain of being entered like this, with the dildo being far larger than his recently extricated fingers. As he struggled, for the third time today her face, upper body and breasts flushed deep red as her internal muscles resisted penetration by the chunky, ribbed and veined black rubber object.

After a minute or so of effort, Ava began to relax, and Lorenzo managed to slip the last two inches of the dildo inside, her sphincter muscle suddenly sucking in the rubber device, closing tightly around its slim neck. The wide oval base of the silicone cock now nestled snugly between her rounded buttocks, the strap holding it wedged between her tight butt cheeks.

Ava desperately stifled crying out at the discomfort and indignation at the huge anal intrusion. Before she could make a sound, Lorenzo pulled the strap up smartly between her open legs. She cried aloud as, grabbing her hips to steady himself and without a pause, he plunged the much larger eight-inch long flexible dildo straight up between her waiting, sopping pussy lips.

Ava began to squeal in panic and fright, as the considerable girth and length of the thick-veined monster cock filled her vagina. Given how lubricated she was, within a few moments the cock, with its wide two-inch diameter flange, was sucked in and buried completely within her dripping pussy.

"Is this the biggest thing you've ever had inside you, Ava? You may speak."

Ava groaned again, feeling fully stuffed, her pussy and anus violated by the thick silicone cocks penetrating her. As she shifted her body slightly, she could feel each weighty cock competing for space inside her.

"Yes, master. But please, I really don't think I can handle both of them inside me! They're much too big!"

They were so large the two dildos were almost touching each other through her thin vaginal and anal wall, creating wild thrilling sensations she'd never remotely experienced before.

"Why do you think I put the speculum inside you Ava? And used the pump? It's to start to give your vagina the increased flexibility I need. Your anus is another matter, however. I can see we're going to have to work on that over the next few weeks."

With the obscene cocks now buried firmly inside, moving around in her inner depths as she squirmed and moved her hips, Ava felt herself approaching orgasm. She began to beg.

"Oh, please master, may I cum? Please Lorenzo, please?"

He frowned. She'd used his name again, against the rules he'd given her. But if she was wanting to cum already, he realised the rest of the day held a lot of promise.

"No, slave. I've only just inserted them inside you, and you need to learn to tolerate them. Be quiet and let me finish my work with you. You are my slave so always remember that you call me master, not Lorenzo."

"Yes, master," Ava stuttered, almost breathless with the strong, sensations of what was going on, deep inside her.

Lorenzo latched the strap into the small brass key lock, adjusting the thin leather so it fitted snugly, forcing the thick dual dildos to stay buried deep within her.

"You will keep this on, Ava, and this device will stay here as long as I wish."

He admired the device's snugness, guessing it would be almost invisible, even under even the relatively sheer summer dress he'd selected for her to wear out.

He reached down, studying the silky dampness between her legs. He closed the second lock on the front of the waist belt with a loud and satisfying snap, the device now fixed in place at the front near her tiny belly button.

Ava was fully penetrated by the locked belt, unable to remove the dildos or the harness even if she wanted to. Her day of slave training and submission could now begin in earnest. It was time to take Ava into the big wide outdoors, to see how she dealt with being a slave out in public.

"Ava, it's time to get dressed. In the next room you'll find the outfit I want you to wear today, laid out. Remember that whenever you are outside with me, from now on, no bra or panties are allowed at any time."

Ava gulped, desperately trying to overcome the near orgasm now engulfing her.

"I'm going to take you out to lunch now and then, this evening, you will entertain me before dinner, as sex slaves are supposed to do. As always, you will remember to call me 'master' at all times, and you are only ever to cum with my permission. You may speak to indicate you understand what has been said."

"Yes, master. I promise to behave. I will call you master and be your sex slave today. I will only orgasm with your express permission."

"That's good Ava. I remind you of this because, wearing this particular device, there may be occasions during the day you may want to or subconsciously feel the need to orgasm. You must not do that, unless I specifically permit you to. If you fail to comply with my will, as your master, you will quickly understand there are consequences."

"Yes, master," Ava said meekly, desperately trying to control the tremor in her voice.

There was so much to consider in what he'd just said. Ava gulped.

"Excellent. Then let's go out and enjoy this lovely afternoon sunshine!"
