By overwhelming her with sex.

The rhythmic slapping of flesh against flesh filled the room. A male grunt signalled when one of the men was cumming, filling Callisto's woman's pussy, ass, or mouth with their semen. The constant cries of ecstasy told of the effect the merciless gangbang had on the blonde warrior. For while her mind was burning with rage, her body was burning with a sexual fire she could not fight against. The potion they had given her had indeed done exactly as told. Her pleasure senses were raised to be dozens of times higher than normal, everywhere they touched her became unimaginably pleasurable. Her breasts, nipples, clit and pussy had it worse, she had always been sensitive and receptive to a skilled lover, but now she moaned and wailed like a cheap whore as cock after cock was using her to their heart's content. The men laughed and jeered every time they **** her to cum. Bound by the iron restraints, she was unable to escape or deny them the use of her body, and the potion made sure that even the roughest or most inexperienced individual would be able to make her cum.

As was the norm for a while now, a cock was brutally fucking her mouth, forcing the gorgeous woman to suck the large member whether she wanted to or not. It slowed down just a bit and pulled back until just the tip was past her lips. Callisto braced herself for what was to come, and sure enough, a couple of seconds later, a large quantity of semen was shot into her mouth. Her cheeks bulged as her mouth rapidly filled with the man's spunk, the tablet he took ensuring he produced much, much more than what should be normal. With the only alternative being to drown and suffocate, Callisto did her best to swallow as much and as fast as she could. A normal man would have been done by now, but because of the **** they used, he was still going, shooting string after string into her mouth. When he was finally done and withdrew completely, Callisto began coughing violently so she could breathe again. Drops and small strings of white semen fell from her mouth, adding to the copious amounts that were already sticking to the side of her face. She was given a brief moment to catch her breath before her face was pushed back into position, and the next cock was **** through the ring gag holding her mouth open.

Another grunt and she felt her pussy fill up. The **** of the ejaculation shot the semen deep into her pussy, all the way into her unprotected womb. Much like with her mouth, the sheer volume of their orgasms **** their stuff to leak from around the cocks, dripping from her red and swollen pussy, onto the solid oaken table she was strapped against. Right at that moment, the piercings that went through her nipples and clit came to life. They went straight to the highest strength, and the powerful vibrations had her scream and wail in pleasure. The sensitivity of these parts was also raised to be far beyond normal levels, and the resulting pleasure **** itself into her body. Against her will or intent, her pussy began to convulse around the cock that was still emptying itself inside her, further milking him dry. She pulled against the unrelenting restraints, and after only a few seconds of unbearable pleasure, she exploded into orgasm herself.

More semen leaked from her pussy as the now satisfied man left her, the convulsions of her slit pushing out what was left behind inside of her. This time, they didn't even wait for her to catch her breath from her own orgasm, as the next person was already in position, and her still quivering cunt eagerly took his member. The sheer amount of times they had cum inside of her, and her own arousal guaranteed that she was well lubricated, and the fresh cock easily slid inside, until it was buried completely in her exposed pussy.

On and on this went. Man after man, hour after hour. She had no idea how long they had been doing this. Even her rage was slowly beginning to diminish as the sexual onslaught was beginning to take its toll on her. True to their word, the potion they had given her had kept her awake and energized, there was no escape from her predicament, and she was **** to experience it each and every time they took her. When she was given a brief moment of rest, she quickly took in what she could see of herself and the room, and it did not look good for her.

The room itself was filled with men, explaining how they had managed to keep the gangbang going for this long. And her once beautiful body was covered with dried-up semen. As far as she could see, there was not much of her flawless skin that was not covered in some way by their disgusting seed. It had been going for what felt like hours, and still, they showed no sign of wanting to stop. She truly began to fear for her sanity if this kept up.

She saw Alexios approach her, idle toying with the spherical crystal that controlled the magical piercings.

'You really are something special, you know that? Most women we did this on lost their minds long before now, but you seem to retain yourself. This is good, that means we can go even further. We have more toys for women like you, and my friends here don't look like they are finished using your body. But before we continue, I think you have earned a small reward for lasting this long. You look like a whore after a long day of hard work, so let's clean you up a bit so that you are all fresh and clean for when the next round begins.'

He turned to two random men who stood near the door and addressed them in a manner that left no room for objections.

'You two, go collect the two we captured some time ago, the ones from the east.'

The two left with a short nod, and Alexios walked to the small cart that held all of his potion ingredients and began to mix a new bowl of something. meanwhile, the many men in the room had moved to stand against the walls, to leave as much room around the bound warrior as possible. When he was done, he approached Callisto with a new potion and ordered one of the men to hold her head still. Not wanting to find out what the effect would be this time, and feeling already sick from the very large amount of semen she was **** to swallow, Callisto began to struggle as much as her very limited movement allowed. But it was pointless in the end. She could not break free, and the grip on her head ensured that every last drop of the surprisingly sweet liquid was poured into her mouth. Both men stepped away, and Alexios carefully observed Callisto's heaving body.

'This new potion will work wonderfully with what we have already given you. Its first effect will greatly enhance the **** of your orgasm. You already cum fast, now we made sure you also cum hard. And the more you cum, the stronger your next one will be. Each new orgasm will be stronger than the previous until the sheer **** of pleasure will destroy what resistance you have left. The second and final effect will not trigger until a certain condition is met. That condition is that the **** of your orgasm would shatter your mind. We don't want a brain-dead bimbo, we want aware of your new role as our fuck toy. So when your mind is about to be destroyed by the **** of the orgasm, the second effect will prevent it. It will stop you from cumming, until you have recovered enough that you can endure the release.'

He said nothing more, but the look of fear and hatred in the blonde woman's eyes told him everything he needed to know. Just then, the door opened, and the two men returned. Each was holding a finely crafted chain leash that, in turn, was attached to two slim silver collars each worn by a woman. Two completely identical women.

They were, to put it simply, exquisitely beautiful. They looked to be quite young, perhaps even just barely into adulthood, but they were already some of the most beautiful women Callisto had ever seen. They were dressed in what could only be identified as a mockery of the clothes worn by dancers from eastern countries. But where the original was designed to entice and stimulate the senses, teasing the watcher with what was hidden beneath the silken cloth, these were the same only at first glance. The already erotic design was further altered to expose even more flesh. And while the cloth of their outfit was clearly of the highest quality, it was also so thin that it partially revealed what was supposed to be hidden, ruining part of the teasing effect of the original design.

What it did reveal though, were the bodies of two extremely beautiful women. They had almond skin devoid of any blemish, that shimmered lightly from whatever oils they had applied, giving them an exotic look so uncommon in Greece. Long legs that told of hours of practising the sensual arts of their dance. Limber arms that ended in slender hands, each trained to entice the watcher with each touch or caress. Their torso's trained to perfection through long days of physical exercise. The iridescent fabric of their clothes shimmered in the light, subtly, or not so subtly at times, hinting at the swell of their breasts. Said breasts stood firm and full atop their chests, drawing attention from anyone nearby as they slowly rose and fell with each measured breath they took. Two dark nipples faintly poked at the fabric of their top, showing their own arousal to any who saw. The sheer fabric around their hips barely covered what it was supposed to, and in the right light, one could see the minuscule string they wore to cover their most private parts. A slender neck called out enticingly to kiss or caress. Their faces were nothing short of perfect. Delicate cheekbones usually associated with aristocracy told of their noble heritage. Thin lips, coloured in deep red and pressed into a sensual smile. A small nose guided the eyes of onlookers into the women's own, where they would be captured by two orbs of deep dark brown. Long and silky tresses of midnight black hair fell to their waists, and the only thing differing the two sisters, and twin sisters they were, was the way they wore it. One had it in an elegant braid that swayed ever so slightly as she moved her head, while the other wore it loose in long flowing curls.

They were, in short, perfect examples of feminine beauty, and Callisto was not ashamed to admit that she felt slightly jealous of their looks. Jealous, but also hungry for a desire that was starting to grow within her that she had not had for another woman in a long while. It appeared that the chain leashes held by the two men were mostly symbolic of their station among these slavers, for their hands and feet remained unbound, and they showed no sign of wanting to escape. Nor did they look like they were here against their wishes.

'These fine sisters were once famous dancers among the courts of the east. Their presence was requested by many and nobles flocked from far and wide to watch one of their marvellous performances. They were so famous in fact, that one of the richer lords of Athens bartered for a night of entertainment. No doubt he paid their father an outrageous sum to have their journey arranged. If only the one he tasked to make it happen wasn't part of our group. It was little trouble to find out in which inn they slept at what time, and a quick sleeping potion for them and their guards ensured they are now ours. They resisted, of course, they all do at first. But despite how erotic and sensual their shows are, they had no experience when it came to the art of the flesh. They broke so fast, it was almost too easy. But now they are true mistresses of the erotic dance, the implied sensuality backed by experience. In fact, a demonstration is in order. The men deserve some entertainment, and you have earned a small reward for holding out until now.'

Alexios approached the sisters and whispered something in their ears. The two shared a look and had a silent conversation that only twins can have before they walked to the middle of the room, conveniently, right in front of Callisto. One of the men behind her reached beneath the table, and after a metallic click, the whole surface tilted slightly forward, giving her a better view of the space in front of her.

The two slowly began to move to music only they could hear. Their bodies swayed from side to side as their arms and legs gracefully moved in patterns that invoked love and sensuality. As they moved and danced through the centre of the room, their motions became fiercer, no longer hinting at a gentle love, but going more towards passionate lovemaking. During their dance, the sisters had ever so slightly begun to mirror their movements, creating a synergy of sisterly love, and erotic passion. Their breasts swayed gently with each sudden movement, drawing eyes to the glistening fabric that barely covered their firm mounds.

Callisto was mesmerized by the display before her. She had seen plenty of dances before, but nothing like this. The way their bodies moved and swayed to some unheard music stirred something inside of her. Something fiery, and an ember of the same passion the sisters expressed through their dance began to smoulder between her legs. Bound as she was, she was in no position to do anything, nothing but watch as the two identical women once again increased the fervour of their performance.

Their arms moved in fierce patterns, mimicking raw sexual lust. they had gradually begun to move closer to each other, and their hands only barely refrained from touching the other's body. Yet the way they moved left no room for doubt, this was no longer a dance to entice but was slowly changing into a display of sexuality. The effect their movements had on the room was painfully clear, many of the men's members had become painfully hard during the sister's display, and a few were openly masturbating to relieve some tension.

Again the twins changed their dance. Stepping closer as their bodies twisted and turned their arms and legs weaving around each other in complex patterns that visualised unrestrained sex. With a final step, their bodies finally touched, their nipples, stiff from their erotic endeavour, brushed against each other, and the dancing sisters let out a soft, yet lustful moan. Their hands no longer pretended to imitate, instead, they freely moved all across the other's body. In perfect unison, they moved their heads towards each other, and after sharing a blazing look of barely contained desire, pressed their lips against each other.

Callisto watched with clear amazement, her dangerous predicament completely forgotten. All she could focus on was the carnal display of forbidden lust between the identical sisters. Their moans and wails filled the room as their hands continued to move across the other's body, hitting sweet spots that further raised their feverish lovemaking. Calisto herself was not unaffected by the display, for she clearly felt the heat burning within her. The dance had awoken her desires and she subconsciously moved her hand so she could tend to her needs like the men around her. However, the rattle of iron reminded her that she was still bound to the table, so she could do nothing to sate the fire between her legs. This was turning out to be a new torment all of its own. The sudden hum of the piercings instantly drew her attention away from the kissing sisters, and before she could stop it, a moan of pleasure escaped her gagged mouth. Her nipples and clit were on fire as the potion's effect had raised their sensitivity to absurd heights. As excited as she was, it took no time at all before she felt the familiar pressure of an orgasm begin to build inside of her. She gyrated her hips against the empty air, making the restraints clank and rattle. Higher and higher the pressure rose until it became unbearable. There was a brief moment where it threatened to overwhelm her before it exploded with a **** she had never before experienced. She shook and trembled as euphoria flooded her senses, drowning her in an orgasm high like nothing before it. As sudden as it started, the vibrations stopped, and she was left to simmer in the afterglow of a very strong orgasm. But after a short moment, her eyes once more found themself entranced by the twins before her, still locked in a passionate kiss, their hands still freely playing with each other.

The dance had long since stopped, but that did not mean that the show was over. After a while, one of the girls moved her hands down along her sister's back. Down all the way, until she reached the other's firm round ass, which she quickly took in a hold. She began to skillfully squeeze her sister's ass, making the soft flesh bulge between her delicate fingers. After a brief moment, said sister could no longer hold back, and she broke the passionate kiss as a lustful moan escaped her lips. The knowing smirk sported by the other twin made it clear this was intentional and with an impressive display of skill and arm strength, she turned her sister around, pulling them against each other until her breasts pressed firmly against the other's back. Not stopping for a moment, she continued to let her hands move all across her twin's body, while her mouth was placing soft kisses on her neck, and occasionally playfully biting her sensitive earlobe.

The other sister made no attempt to move away from her twin's touch. Instead, she was resting her head against her sister's shoulder, eyes closed as hands freely touched her in all of her sensitive places. In the light of the room, Callisto could clearly see the nipples on her breasts standing out so firm and erect, the thin gossamer fabric doing nothing to hide them from view. Undeterred, the young woman's hands finally settled on her sister's breasts, and with obvious skill began to fondle the soft yet firm mounds. They squeezed and massaged the flesh, pinched and tweaked the sensitive nipples, and all this time, the other woman let out soft moans of pleasure that frequently stirred the fire between Callisto's legs. After several minutes of this, one hand ever so slowly started to move down, across the belly, until it had reached its intended destination, the throbbing and so far neglected clit. A single masterful brush against the erect nub had her howling in pleasure as her entire body arched, pressing her hips out to better allow access to her sister's skilful fingers. A mix of softly spoken foreign encouragement and wanton moans and pants filled the room as the twins continued their unholy lovemaking. But the end result was never in doubt, as the cries of pleasure rose higher and higher, and one sister began to gyrate her body more frantically against the other's hands, it was evident to everyone in the room what was going to happen. There was a loud cry of pure unrestrained lust as the twin that was being pleasured began to shake violently. The flimsy material of her thong took on a darker hue, and a trickle of clear liquid seeped through it, flowing down her thighs. No longer having the strength to hold herself up, she sank to the ground, lovingly guided by her sister to make sure she would not hurt herself.

For a while, the two young women sat in the middle of the room, one's back against the other's chest, breathing heavily as she slowly recovered from what was clearly an intense orgasm. Their hands had once more begun to touch each other, and they turned their bodies in such a way that there was nothing hindering them from engaging in another blisteringly passionate kissing session. This time, it was the other sister who took the initiative, pushing her sibling down until she was laying on her back. The top sister broke the kiss, but never really left gently moved down, pressing kisses along her sister's neck, collarbone, between her breasts, until she veered off, and started to use her tongue to flick the erect nipple that capped the soft breast. This time, it was the other sister that mewled in pleasure, as her sensitive breasts and nipples were masterfully licked, sucked or even gently bitten. She alternated between the left and right breast, never truly establishing a pattern. This went on for a long time, lavishing her sister's breasts and nipples with attention, until she suddenly decided she had enough, and moved further down. She traced her tongue across the toned stomach, causing the other twin to shiver pleasurably, before her mouth stopped between her legs, right above her pussy.

Still using just her mouth, the young dancer pushed aside the thin fabric that fell over the hips, before doing the same with the flimsy material of the barely-there thong. She exposed a perfectly bald pussy, glistening with desire. She lowered her head and began to lick the sides of her sister's slit. Said sister took her twin's head by the hair, and gently held her in place, preventing her from pulling away, not that the other girl showed any sign of wanting to do so. In fact, Callisto saw her tongue twirling around the throbbing clit, and the animalistic moan that erupted from the other woman had her own pussy twitched in wanton desire as fresh waves of need radiated out from her groin. Continuing her loving ministrations of her sister's clit, she finally began to use her hand. She reached for the quivering opening beneath her mouth and pushed in two fingers. A contend sigh could be heard from the other woman, and it quickly turned into a soft moan as the fingers began to retreat. As they did, Callisto saw that it was holding something, the base of what appeared to be a smoothly polished wooden dildo. The object was pushed completely into the girl's pussy, and held in place by the thong. But now that her sister had a grip on the sex toy, she began to thrust the wooden object back and forth, all while never ceasing her skilful attack on her twin's clit.

The other twin let out a loud wail of renewed pleasure, and she wrapped her legs around her sister's head, firmly pushing her against her gushing slit. More minutes went by, as the pace of the toy fucking her slowly increased, while the **** of the mouth on her clit intensified. A piercing cry signalled the inevitable conclusion of their lovemaking, and as the smooth dildo trusted back and forth, the twin whose head was locked between the other's legs bit down on the sensitive clit. The young dancer arched her entire body off the ground, pushing her breasts and hips up, and further against her sister's mouth. She became rigid for a moment, her body locked in that enticing position before a guttural grunt signalled her release. Her hips started to shake uncontrollably, and droplets of clear liquid could be seen flying around as the **** of her orgasm had her squirt into her sister's face.

The other woman never stopped her lovemaking to her sister, gently altering her actions to guide her through her orgasm. It wasn't until the shaking stopped, that she released the clit from her mouth. In a quick motion of practised ease, the dildo was pushed back into the other woman's pussy, eliciting a soft moan of satisfaction, before the thong and covering fabric was put back in place. She crawled back so she lay partially on top of her sister, and for a long time, the only sound in the room where the sweet words whispered to each other in a foreign language few people present could understand.

Alexios approached a silent Callisto, amusement clear on his face. He signalled the man behind her, and with a sudden swing of the table, she was pushed back into a horizontal position.

'Quite a show, isn't it? They will command quite a hefty price from whoever wishes to arrange their services. But I'm sure many an underground brothel and even some of the more savoury nobles will pay happily for a show like this. I wonder what their father would think should he ever find out what has become of his beloved daughters. But this was not the only reason they are here. As you have seen, they are quite skilled at delivering pleasure. And they take great joy in playing with another female. Let's give them some time to recover from their show before we include them in your training.
