Natalie was up early, too excited to sleep. She spent time carefully showering, fixing her hair, and applying her makeup. She was standing, nude, in her cabin trying to decide what to wear, although she knew it wouldn't matter for long.

She finally chose her new white bikini. It was tiny, much more daring than anything she would have ever worn back home, and it set off her dark olive skin beautifully. Her breasts jutted out, completely filling the small triangles that served as the bra of the bikini. She noticed, with a slight blush, that her nipples were already hard and clearly visible as they threatened to poke holes in the material.

The bottom of the suit was disgracefully small and Natalie realized that she was going to have to do some serious bush trimming before she made her first appearance to the group. The back was just a thin strip of material that ran up the crack of her ass and concealed nothing except the puckered opening of her asshole. Tiny strings held everything together. As she studied herself in the mirror Natalie decided that she had achieved the effect she was looking for, sexy and hot, but slightly naive and virginal. Her outfit showed off her tight, firm body to the best possible advantage.

Natalie was fawned over at breakfast. The others waited on her, treating her like a queen. The young teacher enjoyed the attention and savored the slow build up of the sexual tension. By the time the dishes were cleared everyone was ready for the games to begin, especially Natalie, who was already trembling with a delicious mixture of fear, excitement, and anticipation.

Bill stood and moved out to the cockpit, a silent signal that he was ready to begin. The others filed out behind him, leaving Natalie alone in the salon. She knew that she would be summoned when they were ready for her.

The call came quickly. "Come here, Slut. Your day is about to begin," Bill barked.

Natalie moved on quivering legs up the companionway steps and stood in the center of the cockpit facing her Master, waiting for him to give the command that would start what would probably be the most exciting day of her young life. Her mind was in a turmoil as she fought for control. She was about to experience all the things she had fantasized about, yearned for, and even feared. She prayed that she would be up to the challenge.

Addressing the group, Bill spoke. "Natalie has told me that she wants to experience this day to the fullest. She has requested no safe word and has not set any limits. She is our least experienced member and is completely aware that the others can go places she can't yet travel. Even so, she has expressed a desire to extend herself to the breaking point. I have purposely avoided talking with any of you about this day because I wanted it to be spontaneous. Remember that we have the whole day. There is no need to rush things."

With that said Bill stood and stepped toward the young teacher. He saw a shiver run through her body and knew the rush that she was feeling as her day as a sex toy, slave, and victim was about to begin. He captured her wrists in padded leather cuffs and snapped them together behind her back. The D rings on the cuffs were fastened to a line running to a pulley on the boom. Bill took the slack out of the line and tightened it just enough to force Natalie to bend forward at the waist to relieve some of the pressure on her shoulders. Her ample tits hung down invitingly, practically unencumbered by the tiny swatches of material that served as a bra to her bikini.

Even that was more than Bill wanted, so he untied the string and allowed the bra to fall to the cockpit floor. Exposed to the gentle sea breeze, Natalie's nipples filled with blood and stiffened noticeably. Jimmy jerked on the strings at her hips allowing the bottom of the bikini to join its mate on the floor. Charles and Mike shackled her ankles to the sides of the cockpit, leaving her legs spread almost as wide as possible in an obscene pose. Natalie had never felt so open and exposed. She could feel the breeze wafting between her legs, gently stirring her long, dark pubic hair and rushing over the winking eye of her asshole. Her bent position had already caused her nipples to engorge with blood. Her spread position had put more pressure on her shoulders making her bend forward even more to get some relief. Now she felt her breasts harden as the blood pounded through them.

Natalie's vision was limited due to her position. She could not see anything that was going on behind her and very little at her sides. When she lifted her head to see what was happening in front of her the pressure on her shoulders increased so much that the pain soon forced her to lower her head. She did have a clear view of her tits hanging down and thought how inviting they looked. Since this was what occupied her entire field of vision, she focused on them, marveling at the throbbing nipples and feeling the subtle pounding of her heart as the blood coursed through the hardening mounds of female flesh. She knew that her precious tits would get a lot of abuse today and the thought excited her. They were extremely sensitive, especially once they had gotten hard like they were now.

Bill had already accomplished one of his goals. He had Natalie's mind focused on sex and her body. A slight burn in the muscles that ran the length of her thighs forced Natalie's attention away from her tits. She was proud of her legs and knew that they were one of her best features, always drawing admiring glances from men. She could tell that they were being shown off to their best advantage by this position. Spread wide apart as they were, the tendons that ran along the insides of her thighs stood out, as did the muscles in her calves and up the backs of her thighs.

This train of thought naturally led her to imagining what her ass must look like. It was the one feature of her body that had always been a point of concern with her. She felt it was too big and not firm enough, although since joining the club it had not worried her quite so much. All the guys seemed to like her ass, never failing to comment on how they loved watching it jiggle when they spanked her. It had not escaped her notice that someone always seemed to be patting or squeezing her ass during sex sessions with the group. She had almost overcome the negative feelings about her ass and had begun to think of it as one of her better features.

As with most people, playful sex spankings were what had first peaked her interest about this lifestyle. She found herself getting extremely turned on while being spanked and discovered that when she was both tied and spanked the sensation was almost overwhelming. Her efforts to explore these feelings in greater depth had been mostly unsuccessful until she found Connie and Bill and had joined the group. Although she was still relatively inexperienced, she had taken part enough to know that this was what she had been missing all her life.

Sex had been pleasant before but was certainly nothing that could have been described as earth-shattering. Now she found herself eagerly anticipating each gathering of the group. She fantasized for days before a meeting and relived each moment afterwards. She always reached orgasm during the sessions, usually several times, whereas before, during regular sex, she was frequently left frustrated, on the verge, but unable to go over the top. Natalie had alternately blamed her sex partners for their lack of expertise or herself for being unresponsive when this happened. Now she understood that fifteen minutes of breast and genital manipulation, sometimes with a little oral stimulation thrown in for good measure, was simply not enough foreplay to get her going. She loved the long, drawn out sessions, where her mind and her body became totally focused on sex. The pain and the bondage added a spice that intensified the episode and allowed her to immerse herself in the sensations her body was experiencing.

A persistent tickling sensation on her tits and the backs of her thighs forced Natalie out of her reverie. Her wandering mind now focused sharply on what was happening. She saw the long feathers attacking her hanging globes and identified the identical sensation behind her. Whoever was wielding these seemingly innocuous implements were driving her crazy! The feathers would lightly tap at her nipples, bringing them to full erection, then would move to the base and saw back and forth as if trying to lop them off. Occasionally they would leave her nipples to run rampant over the rest of her expanded and sensitive breasts. This left her panting and moaning, wishing for a stronger, more tactile sensation. After a few minutes of this tantalizing torture Natalie found herself ready to scream. She wanted someone to slap her tits, squeeze them, or whip them. She would gladly have begged someone to pinch her nipples hard and twist them cruelly. At this point she would have welcomed the punishing nipple clamps that hurt so badly at first but soon provided just the right amount of pain to send her soaring off into the subspace reserved for the truly submissive person.

The feathers evoked equally maddening responses behind her, perhaps even more so because of their proximity to her asshole and pussy. They seemed to work in unison, fluttering up the insides of her thighs, gently stroking her rapidly expanding and moistening pussy lips, curving around to caress the winking pucker of her asshole then gently cascading down the backs of her thighs to the sensitive area behind her knees. Natalie felt the muscles in her legs twitch in response to the gentle brushing of the feathers. She also felt the moisture well up in her pussy and knew that it would soon spill out and run down her thighs in thick, gooey rivulets. God! She was so turned on and the party had just barely begun!

As soon as Bill saw the first evidence of lubrication seep out of Natalie's swollen labia he nodded to the others to stop working her over with the feathers. It was time to move to the next level of stimulation. He knew that she was now acutely aware of all of her erogenous zones and that her nerve endings were primed and ready for stronger sensations. It was too early for her first orgasm so he knew they would have to handle the next step with care. He wanted to replace the gentle stimulation of the feathers with a light but perceptible layer of discomfort, nothing too painful, but enough to further heighten her awareness and help her begin her spiraling journey into submission and sexual abandonment.

He chose a very light multi-stranded whip for this purpose. The tails were about a half inch wide so that they wouldn't cut into the skin and were very thin. Even if wielded with a strong arm there would be little more than a stinging sensation and a slight reddening of the whipped area. Bill moved behind Natalie and let the tails of the whip rest on her back. Moving it slowly, he noticed her ass cheeks twitch when he ran the leather tips over the taut smoothness of her half moons. He began a slow circular motion which caused the leather fingers to brush against her skin raising goose-bumps as it traveled over her back to her ass and down her legs. Moving from one side to the other he was able to direct the gentle blows to the sides of her hanging tits and nipples. Natalie let out a surprised moan when Bill directed the whip into the hot vee of her crotch. She had never been whipped on her pussy and although this could hardly be classified as a whipping, it foretold of things to come. Her level of excitement was growing as was evidenced by the increased flow of thick lubrication running down her thighs.

Bill repeated the pattern five more times, gradually increasing the strength of the blows. By the final time, Natalie was being treated to yet another assault on her senses. She was not only feeling the leather thongs nip at her unprotected flesh but she could also hear the satisfying snap when leather made contact with moist, eager skin. By the time he finished, the young teacher was panting and moaning from excitement and was hovering just on the edge of an orgasm. She cried out in frustration when he quit, knowing that she would have to wait for the sweet release that she now so desperately craved. She was well on her way to finding that dark area of her mind that allowed her to lose all inhibitions and succumb to the carnal cravings of lust. The needs of her body were all that mattered and nothing was too outrageous or too depraved if it helped her reach her goal.

Natalie was so lost in the feelings of the moment that she was barely aware that she had been released and rebound in a different position. When her mind finally cleared she realized that she was now suspended from the boom by her outstretched arms. Her legs were still spread wide but had been attached to different points on the boat. Assessing her position, she could tell that she formed a human "X" and was, if anything, even more exposed and vulnerable than before. The pressure on her shoulders had been relaxed, and although she was supported only by the straps around her wrists, she was a little more comfortable than before.

Bill turned the whip over to Jimmy, much to Natalie's delight. She hoped that Jimmy, being so young, would not have the finesse of his father. She was hoping that he would be more aggressive and go too far in his eagerness. She had come down a little from her sexual high but was still in a state of extreme excitation. If Jimmy made just a small mistake she knew that she would crash over the edge, something that she fervently wanted to happen.

Jimmy, however, had learned his lessons well. He was experienced far beyond his years and had been practicing on Connie, Rosie, Kim, and Jean, four women who knew what they wanted and didn't hesitate to explain and teach the young Master-in-training. He stepped behind the stretched, suspended form of the young Spanish lady and delivered five quick slashes to her back, using the forehand, backhand technique. Natalie was unprepared for the assault and let several yelps escape as the sharp pain shook her bound body.

The stinging continued long after the teenager had stopped whipping her, leaving Natalie to twist and turn as much as her severely limited position would allow. As she writhed and undulated, trying to get control, she realized that, in just a few seconds, Jimmy had managed to bring her right back to the peak of desire that she reached earlier. Circling her, Jimmy repeated the whipping on her front side, carefully avoiding hitting her tits or pussy. By the time he finished, Natalie was screaming, surging against the ropes that held her so tightly. Her stomach, from beneath her breasts to the line of her pubic hair, was criss-crossed with faint red lines, as were her thighs, where Jimmy had aimed the last two blows.

The pain had two conflicting effects. It had fanned the fires of her passion to a white-hot glow, but had been just severe enough to force a small part of brain to focus on the pain rather than the pleasure, leaving her short of her desired goal once again. What did not show was that Jimmy had successfully accomplished the mark of every Master. He had taken control of his subject. She was his now, just as she had been his father's before. Natalie no longer saw Jimmy as a teenage boy. He was her Master and she was willing to serve him in any way he chose.

Bill recognized her change of attitude. She had now accepted two of them as her Master and he wanted to push her further into the depths of submission by making her understand that it didn't matter who controlled her. All that was important was that she was a slave and her role was to serve and accept anything and anyone who stepped forward to take charge.

It was time to move to the next level and Bill had two objectives in mind. Natalie was the primary player and he wanted to drive her deep within herself, to help her reach the level of submission that he knew she craved. A secondary, but important, part of his long range plan was to train one of the women in the art of domination. It was the one element that was missing in their club. Michael filled the role as a submissive male but none of the women had stepped forward to play the part of a Dominatrix.

Bill knew who he wanted to fill the position. Jean had played the part with her husband but had eagerly accepted the subservient role when given the opportunity, so she was not being considered. Rosie, Connie, and Angela were not good candidates. Rosie was the only one of the three with any experience since she had trained Kim before finding Bill and allowing him to take over, but her heart was not in it, and she much preferred the submissive role. Tracy, not being a true member of the group, was not considered. Kim was the best choice.

He had seen it from the beginning. Kim was a Dom playing the role of a Sub because it pleased her to do so and it was her ticket into playing sex games with the adults. He had watched the way her eyes sparkled while she described her scene with Angela before they inducted the young blond into the group. She had clearly enjoyed being the Mistress. Perhaps she was one of the very few who could actually go both ways and enjoy either role to the fullest. Most, like Jean, much preferred one role or the other and only switched out of necessity.

Calling Kim over, Bill spoke with her in whispers. The excited bobbing of the girl's head showed her approval of what he was saying. Once he had given his instructions Bill sat down next to Rosie to watch the show. He spoke to his neighbor quietly, "Watch carefully. After this you may find that you and Kim will be having a much different relationship than before. Instead of mother and daughter it may well be Mistress and slave, with you on the receiving end. Do you think you could handle that?"

"If she is a true Mistress then I wouldn't have any choice, would I?" Rosie answered. "Train her well. I need what you give me and if you think she is capable, then by all means, go for it. I think it might be very exciting to live as a full time slave to my own daughter. I hope it doesn't mean that you are abandoning me. I don't think I could stand that."

"Oh no." Bill answered quickly. "The club will go on as before and I will still maintain control. If this works as I think it will, Kim will act as a sub to me just as before. The only difference is that I will have a Mistress at my side to take over when I choose and add some spice to the sessions. I think our ladies would appreciate the feminine touch occasionally."

"I agree," Rosie said. "There is something about being under the control of another woman that is very exciting. It makes you realize that you are totally submissive, not just playing the role to please a man. It's also more frightening. Women know all the special ways to hurt another woman and they are more ruthless than men. A man, even a good one, will always hold back. A real Sub not only needs the pain but also needs the satisfaction that she has taken everything her Master offers and is willing to do more. We can tell when you are holding back and that taints the illusion a bit. A woman, on the other hand, doesn't have that problem. She knows that her Sub can stand more." She paused and flashed a sly smile to let Bill know that she wasn't putting him down before adding, "And, she isn't bound by the laws of nature that say a man is supposed to protect a woman."

Bill nodded understandingly. The hardest job he faced as a Master was to find the line where sex ends and true torture begins. It was different for each of his women and he was constantly fearful that he would go too far with one of them, breaking the bond of trust and giving them an unpleasant experience. The fact that they so often wanted to play without safe words made his task, and his responsibility, that much more difficult. Rosie was gently chiding him about what he already knew. He often erred on the safe side. It was easy to find the limit where the pain replaced any feelings of pleasure. What was so difficult for him was to know how far into the dark side he should go and how long he should remain there. With Kim having been there many times, he was hoping that she would help fill this particular need for the others while allowing him to observe and learn.

Kim surveyed her charge and trembled as the feeling of power surged through her. She was being given a chance to prove herself worthy of Bill's faith and trust. This was not a complete surprise to the young girl. They had talked about this before and Kim had let him know that it was something she wanted to try. Her experience with Angela in the gym had given her a taste of the other side and she had wanted to investigate it farther.

Natalie's face registered her disappointment. She had been looking forward to her day of submission and sex with her Master. She had never played sex games with another woman and didn't find the idea very appealing. She did realize, however, that she was the slave and had no control over the events of the day, so she voiced no disapproval, choosing, instead, to play her role to the best of her ability. She was Bill's toy, and if this was what he wanted, then she would try her best to please him.

Kim went to work immediately. She selected a red, rubber ball gag and a leather blindfold, Forcing Natalie's jaws wide apart, she strapped the gag into place. Natalie was already beginning to drool down the corners of her mouth by the time her vision had been taken away by the blindfold.

Icy shivers shot through her body when Kim said, "You made a mistake by choosing to not have a safe word. I'm going to hurt you badly and I'm not going to stop until he makes me quit. Later, I may take the gag off so that I can hear you scream and beg. Before we are done, you will be offering to do anything, with anyone, to make the pain go away."

Although she was very afraid, Natalie could not dismiss the feeling of extreme arousal that coursed through her body. This was exactly what she was looking for and had been hoping that Bill would provide. Unable to see or speak, Natalie knew there was no way out and no turning back.

Kim wanted to exert her authority and take control of the situation quickly but, at the same time, she knew she had to be careful to not push Natalie too far or too fast. With this in mind she selected a thin, whippy cane for her first round with the young teacher.

Natalie's nostrils flared when she felt the cool, smooth surface of the rod as Kim rubbed it slowly over her body. She identified it immediately and visions of previous sessions swirled through her head. She had witnessed all of the others having encounters with the cane and the images remained imprinted in her brain. She could still hear the moaning and crying as the vicious instrument sliced into white, smooth skin, leaving angry, red welts that soon turned purple with yellowish outlines.

As the cane caressed her breasts, gently hefting each one, sawing back and forth across her nipples, stroking softly from her collar bone to her areolae, she remembered one particularly licentious evening when Rosie took a severe caning of her tits. She had asked for it and her wish had been granted. At one point she had even been suspended by her ankles so that the soft, undersides of her huge globes was exposed and beaten. Natalie had witnessed Rosie cumming at least 10 times from just the beating and remembered yearning for the same treatment. Now that it was about to happen she was flooded with conflicting emotions. The excitement made her breasts hard and her nipples stand out, quivering and ready, but the fear was almost overpowering. She knew that she was about to be hurt more than ever before and she desperately hoped that she would be strong enough to take it. More importantly, she prayed that the result would make it worthwhile.

The blindfold and gag heightened her other senses. She heard the swish of the cane cutting through the air long before she felt the impact as it sliced into the meaty portion of her breasts above her areolae. Time seemed to stop while she waited for the pain to register. When it finally burrowed into the deep recesses of her mind she felt an agony that far surpassed any she had suffered before. The ball gag kept her from screaming out loud but her thrashing and moaning were clear indications of her torment. Kim delivered five hard cuts in rapid succession, the last one landing squarely across Natalie's nipples, driving them deeply into the surrounding breast flesh.

The first four blows convinced Natalie that she had been delivered to the nether region of Hell and into the arms of the Devil himself. She had never experienced such pain and was very nearly driven insane by its intensity. The last blow froze her. Everything seemed to move in slow motion. She clearly heard the whoosh of the cane and felt the contact of the smooth wood against her nipples. In her mind's eye she saw her nipples disappear into her breast flesh as the cane continued on, burying itself deep in her tortured tits, leaving each tit with its own deep cleavage as it, too, was engulfed by the soft tissue of her ample bosom.

Natalie had time to scream to herself, "No! Not there. It'll kill me!" before the pain hit. She felt it first in the pit of her stomach. It felt as if she had been punched hard, her breath driven from her lungs by a powerful blow. It spread like molten lava, consuming everything in its path. Her entire body was on fire. Every nerve ending sent out shock waves, warning of anguish beyond belief. Her nipples turned white-hot and throbbed so furiously she thought they would explode like Fourth of July firecrackers. Her toes curled tightly, tensing every muscle in her legs. She felt her fingernails drawing blood in the palms of her hands.

She screamed. The sound echoed through her head with a decibel level equal to the incredible pain in her tits. She kept screaming, increasing her cries of agony and utter despair as the pain kept spiraling upward, finally engulfing her entire body. Of course, the ball gag reduced her maniacal wailing to mere squeaks and sobs, barely audible over the gentle sea breeze.

While all of this took several minutes in her distorted sense of time, in reality it happened in a fraction of a second. By the time the cane had rebounded off of her bruised and tortured flesh the worst was over. She hung limply in her bonds as her muscles gradually relaxed, and she began to notice an entirely different feeling creeping through her, displacing the powerful sensations of pain and torment with equally strong feelings of urgency and arousal.

Her buttock and stomach muscles would not relax. They remained clenched, giving her that "washboard" effect so prized by body builders. Her pussy seemed to have taken on a life of its own. Natalie felt the rippling of her muscles way up inside her. She suddenly realized that she could not remember the pain. All that occupied her mind were unimaginably intense feelings of pleasure, desire and need. She had been driven to a level of excitement that far exceeded anything she had ever experienced.

At last it was clear to her. It was what the others had found but had been unable to convey to her in a way that she could understand. It was what kept them coming back for more abuse and begging for even harsher treatment. She was in the throes of a full blown orgasm that wouldn't quit and wouldn't peak! She kept cumming and cumming, existing in a state of indescribable ecstasy that seemed to know no limits but held the promise of even greater pleasure if one were willing to suffer what it took to get there. The last thing she remembered was thinking that she had to feel like this again. No amount of pain, no act of degradation or humiliation was too much to pay for another chance to reach this level of sheer erotic bliss. If there had been fear and doubt before, all questions had been answered and uncertainties dispelled. There was absolutely no question in her mind that she would dedicate the rest of her life to the pursuance of the state of being that she had just experienced.

Since time and awareness had stopped for her, Natalie was surprised when she finally came around and discovered that she had been released and was laid out on one of the cockpit seats. Later, she found out that she had orgasmed for more than five minutes, finally passing out from sensory overload. More than ten minutes had passed since she had been taken down. A quick check confirmed that she had been thoroughly chastised. Her tits showed dark bruises with tiny patches of broken skin. Gently touching her nipples, Natalie grimaced as fresh pain shot through her body. She would be sore for several days, but it was not something that bothered her. In fact, she wished she could do it all over again!

As soon as Kim noticed that Natalie was conscious again, she moved to continue her session with her. The young girl knew that her subject would not be able to take more breast abuse, but she still had several other avenues open to her. Natalie had never had her pussy or asshole whipped and that was exactly what Kim had in mind, but first it was time to get some of the others involved. Everyone else had been watching Natalie and Kim and were ready for some action themselves. The neophyte mistress knew that being a spectator for a while would excite Natalie and get her ready for her next ordeal.

As the sun rose the following day the vacation cruise of the Neighborhood Sex and Torture Club came to a close. The members all agreed that it had been one of the best times of their lives and that it must be repeated on an annual basis. Their new friends, Tracy and Mike, agreed and offered their boat, free of charge, for future bondage cruises. They also promised to visit the mainland every couple of months to participate in some "warm-up" orgies just to keep up with the rest of the group. Kim was now a confirmed Mistress and would take her place at Bill's side on those occasions that he wanted some help or to add some variety to their parties. Natalie was "broken" to the lifestyle and soon began rivaling Connie and Rosie in her quest for harsher treatment.

The End
