This is a fairly long fictional story separated into a first act (more focus on sex) and a second act (more focus on story). Only the first act can be properly read without reading the second act. In regards to theming, both acts of the story mainly describe the gradual and sexual escalation of clueless or naive women. It quickly becomes quite extreme, non-consensual, cruel, and tortuous. It is definitely not for the faint of heart (however, no cannibalism, scatology, or snuff).
X. The level 9 of sister Mary
Sister Mary continues to practice with larger toys and gradually gets used to getting impaled by the massive cock of the stallion. With time, she more and more enjoy getting being stuffed by her gigantic lover and eventually fucks her stallion even in the evening when no master is around. Her hard work pays off and after a total of 270 days, she meets the requirements for level 9. Her ass can take a circumference of 46 cm (18.1 inches) with a flexible depth of 90 cm (35.4 inches/2.9 feet) and a stiff depth of 47 cm (18.5 inches), where she can almost take her stallion balls deep. Her pussy now can take a circumference of 50 cm (19.7 inches) and a depth of 38 cm (15 inches).
After fucking her dearest father John, he expands her tits to 4000cc (expandable to 5000cc) and receives an emerald collar around her thin neck.
He leads her to her new luxurious chamber with its own inhouse stable accommodating her stallion. The chamber also has a fireplace, a chandelier, and a bubble bath. Furthermore, her pill dosage is increased and she can now request weekly either a trans sister or a sister. Sister Mary is overjoyed, but worried about negative aspects that may await her. However, father John puts her a bit at ease.
“Yes, it will become more difficult, but not by a lot. Restrictions regarding machines and horses will be lifted, but I think you can handle that. Train well, because at level 9, we will send you to other institutes as a temporary exchange sister. The demand for someone as young as you will be high. Don’t bring shame to our institute when you are gone.”
Her eyes grow big and she gets even more giddy than before.
“I always try to be a good girl for you, father John.”
He pats her head and turns around to leave.
“Father John, did I do it? Did I reach the highest level? Or is there a level 10?”
“Right ... yes, there is. But it is rare that someone manages to get that far ... In order to reach level 10, your ass has to take a circumference of 50 cm (19.7 inches) with a flexible depth of 100 cm (39.4 inches/3.3 feet) and a rigid depth of 50 cm (19.7 inches). Your pussy needs to take a circumference of 55 cm (21.7 inches) and a depth of 40 cm (15.7 inches).”
“... that is a lot, father John.”
“But I have faith in you, sister Mary.”
“Me too, and in the lord, father John.”
He needs to turn towards the door, so she can’t see him roll his eyes over her naivety and subsequently leaves her alone.
In the evening, she celebrates by taking her stallion in her ass balls-deep, feeding her foal and subsequently goes to bed, in order to rest for her first day as a level 9 sister.
The next morning, she receives a group of masters that have her ride their cocks while taking her stallion in the ass. However, she has progressed to the point where she struggles so little that she comes more often than her masters.
Once she is through with them all, they take her to the stable for the first time. She knew that her stallion spends the night there, but had no idea what other horses there were.
To her surprise, she finds that some of them are actually smaller. She is first introduced to a pony, with a 20 cm (7.9 inches) penis, which she can easily take in her pussy. She initially loves being able to fully take a horse in a hole other than her ass, and soon after climaxes from the new experience. However, she eventually is rather amused by the thrusts of the cute creature that are timid compared to her stallion. Nonetheless, its tiny efforts do not stay unrewarded when it becomes the first horse that sister Mary manages to deepthroat under cheers of the masters.
At the next box, she finds an equally cute animal in the form of a donkey, sporting a 30 cm (11.8 inches) cock. Still, sister Mary has no problems taking it in her pussy and even manages to deepthroat it, earning her more applause.
With another load in her stomach, she is brought to another box, which houses a horse with a 35 cm (13.8 inches). This one now manages to hit her cervix and not too gently either. But sister Mary is too excited to let that deny her another orgasm. Once she has calmed down, she gets on her knees and tries to get its cock in her mouth. Due to its tapered shape, she gets most of it in her throat, but struggles with the last 5 cm. Still trying to impress her audience, she keeps forcing it further down. However, even after the horse came down her throat a second time, she can’t get it all in. She would have continued trying, but the masters stopped her, to give the horse a rest and in order to bring her to the next box.
Herein lives a slightly larger horse, which does not look too different, but she is somewhat suspicious about the masters appearing more quiet than usual, when she approaches the new animal. Upon stroking the horse, she gasps with wide eyes watching a huge head emerging, followed by a thick shaft. At full size, its cock is only 30 cm (11.8 inches) long, but the circumference is approximately 40 cm (15.7 inches).
“Masters, will you look at the width of that thing! It has veins all over it as well!”
The masters are bawling and laughing, having hoped for such a reaction.
“Well honey, you showed us what you can do with your throat and ass, so we wanted to treat you to a nice cock for your pussy.”
Sister Mary smiles while still stroking the fat member.
“I want to say I love it, but I haven’t tried it yet. May I, master?”
“Go ahead, we insist!”
She crawls under the horse and guides the big cock head to her pussy. The horse plunges forward, trying to enter the little girl, but can’t get inside, causing her to get pushed forward a few steps. A bit embarrassed by her tumble, she tries again, however, angling her pelvis in a better way before touching the cock. After some pushing, the horse manages to drive half of his shaft into sister Mary, who she has to lean forward, in order to recover from the large and sudden insertion. She had bigger toys up her pussy, but never a cock of such a size and attached to an animal 10 times her weight and power.
Nonetheless, she wants it all and gradually inserts more each time the horse plunges into her hungry pussy. Her moans are getting louder and louder, culminating in a big groan when the last inch is buried deep inside of her. The horse does not give her much time to rest and starts pumping in and out of his new fuck hole. Sister Mary closes her eyes and focuses in order to adjust to the large piece of meat driving in and out of her, which gradually allows her to enjoy this new experience.
Having a well-trained pussy that can accommodate such a wide cock arouses her on a lot and she can feel that the horse is enjoying her as well. The animal is pumping faster, enjoying the capable human pussy, but she wants more. Sister Mary starts to back into him, matching his movements in order to smack her ass against the base of the girthy member. Her enthusiasm fires him up, causing him to plunge more furiously into the girl. She wins the race to the climax when she moans loudly, barely being able to stand on her legs, while her body rewards her with waves of pleasure.
Not long after, she can feel him filling her up with his seed. However, neither of them stops fucking and the room is soon filled with more groaning and slapping noises, while he is pumping half his previous load out her ravaged pussy. Once they both come a second time, she finally pulls out and gets to rest for a few minutes on a chair, with a smile on her face and horse cum oozing out her pussy. After she cleans herself up, she is led to her last box.
When she looks inside, she gasps with wide eyes. It’s her stallion and some other animal ... what is it ... her sire! She immediately jumps into the box in order to greet her old mate. After she gets to cuddle with the wolf for a bit, she is asked to take them both at the same time. The task intimidates her at first, but her loins are aching for her mates already and she wants to reward her masters with a good show for all the fun she had.
Sister Mary starts by gently sucking them both to full length, but taking a bit more time with her sire, to savor the rare moment with her old lover. Then she lies the sire on his back, straddling the wolf his cock in her yearning pussy. Once her pussy lips close around the knot, she grabs the cock of her stallion behind her and slowly guides him to her ass.
With her sire stretching out her pussy, it is frustratingly difficult to push the stud into her behind. After many failed attempts to open her ass, her eyes widen when it finally pops inside. For a moment, it gets easier as the stud’s head passes her sire’s cock, but then the tapered horse cock begins to stretch her sphincter as the base approaches. Her breathing intensifies, and her holes struggle to accommodate two such huge objects. But her desire to fuck them both is larger than her discomfort and she keeps taking what they offer. She screams out in agony, but keeps urging the horse to push forward. The last few inches, her fire red sphincter feels like it has reached its limit, but she continues taking more by tightening the horse cock with her ass.
Once her stallion is almost at the hilt, she lets out a big groan with her eyes rolling to the back of her head. Her holes are bursting with cock and she can’t get enough of it.
That is, until the horse starts thrusting. With her pussy stretched so much, the tissue between her ass and slit has less wiggle room to accommodate to her ass being shoved around by the horse cock. Sister Mary promptly tries to hold onto the bar above her and places her feet firmly on the ground, but it takes her a few moments to angle her body properly between her anchor points and the member thrusting in her ass.
Once she is in a better position, her screams of pain slowly transition into groaning. The audience is holding its breath, watching her trying to cope with both her lovers. She tries to enjoy her holes being stuffed, but she also has to focus a lot on her position. From time to time, a powerful thrust throws her off and she has to quickly adjust herself in order to reduce lateral forces on her holes.
Slowly but surely, her body is settling in and starts to build towards a climax with every thrust in her ass. However, her aching body can’t take it any longer and she realizes she needs to come before it gives up. She hits her stallion on the side and screams at him to fuck her harder. When he speeds up, she uses her last bit of stamina to rock her ass back and forth, griding her pussy against the sire, while getting railed by the stud. Her breathing gets heavier and her head rolls back, while her legs are starting to tremble. When she can feel both cocks start pumping cum into her stretched holes, her body is pushed over the edge and erupts in a climax accompanied by loud moans from the exhausted girl.
After she has calmed down, she becomes much more aware of the discomfort of her stretched holes. However, when she wants to pull out the monstrous cocks, the masters stop her and insist that she sucks them all off, while continuing to get fucked by the sire and the stallion.
They allow her to keep out 2 inches of horse cock that she had already dragged out of her ass, so she can better focus on pleasing their dicks. Luckily it does not take her too long to get them all off, as the show they just witnessed had made them all rock hard. Once everyone is through, she gives an encore with one more orgasm and then stands up with a smile, pulling out the massive cocks, emptying her holes into a bucket, and swallowing her lover’s seeds.
From then on, sister Mary is brought to the stable more often, where she learns to handle the horse cocks better and better with time. However, she is also introduced to a horse with a 50 cm (19.7 inch) cock that she tries to take in her ass, but it is just too long. As that depth would be required to pass level 10, she keeps trying and even asks the masters to take her to the horse, but she seems to barely make progress. Similarly, when she tries to insert toys during her stretching routine, she seems to hit a barrier. Eventually she gains 1 more centimeter, but can’t get any further than 47 cm.
After three weeks of getting to know the horses in the stable, she is visited by father John, who announces to her that she will visit other institutes.
“We have now finished a plan for your three-week exchange program. You will fly with a private jet of one of the masters to Asia, where you stay for a week. Then, a second master will fly with you to India for a second week, and a third master will fly with you to Africa. Afterwards you come back here.”
“Asia, India, ... what are those, father John?
“They are other parts of the world. We have institutes with sisters and brothers there as well, but with level 9 and 10 sisters being rare, we have exchange programs so more masters can enjoy them. Therefore, you will fly there.”
“Father John, what do you mean by flying? How am I flying with a master?”
“They have machines that can fly, they are called airplanes. Maybe you have seen objects in the sky that make long clouds? We auctioned off your flights among masters that have such airplanes. They will bring you there and in return get to do with you whatever they want during the flight.”
Sister Mary listens with wide opens eyes.
“These are machines that can fly? I can travel with such an airplane? That is incredible!”
Father John is slightly annoyed having to listen to her excited ramblings.
“Sure, but the main goal is to serve the masters in the other institutes. It will be the same schedule, so keep training and serving. Expectations are high and poor performance reflects badly on our institute.”
She composes herself promptly.
“Of course, father John. How should I conduct myself?”
“Don’t talk back, do as you are told, be humble, and don’t give up when it gets difficult.”
A quick nod shows him that she understands. Fearing that she will freeze up in fear at the other institutes, he rolls his eyes a bit and clarifies.
“But you can also enjoy yourself and give them an entertaining show.”
She smiles back at him, but stops when she notices his frustration with the excited girl.
“Tomorrow morning, your first master will pack you up and drive you to his airplane. Be safe.”
The next morning, she is sitting on her bed in anticipation, barely able to contain herself. When her first master comes in, she asks immediately.
“Welcome, master! Do you have a flying machine? Am I going with you?”
“Hahaha, yes, I do and you will fly with me. But first, I need to put you into my hand luggage.”
Managing sister Lottie rolls a trolly with a rack into the chamber, puts the rack on the ground and leaves again. The master takes two boards from the rack and attaches them around her breasts. The combined boards form two round holes in the middle, through which her tits extend. The holes are smaller than her breasts, which means the board is trapped between her body on the one side and her tits on the other side. Sister Mary then has to place the board horizontally on an elevated frame standing on the ground and then arch her legs back over her shoulders. As a result, she is performing a chest stand on top of the board, with her tits hanging out below the board. Bending her body would generally not be as difficult, but she still has her 90 cm (34.4 inches) but plug in her ass, which makes it difficult for her guts to accomodate.
Once the soles of her feet rest on the board, she puts her arms around her ankles and a lid is placed over her, confining her immovably inside. The only reason that she does not panic is that she is not trapped in darkness. The lid has an elongated hole, which keeps her face, ass, and pussy accessible from the outside.
Two men pick up her box, rotate her upside down, so her tits are at the top, and place her on the trolley, with which her master can comfortably pull her, by her tail plug, towards his limousine. Inside the car, the box is mounted at its side onto brackets attached to the roof of the car that hold the box at its center of gravity. As a result, the master can easily rotate the box around an axis parallel to sister Mary’s shoulders.
As soon as the limousine sets off, he gives her a first spin, causing the disoriented girl to scream as she rotates a few times.
“Let’s see with which side I will play with first.”
The box eventually stops with her tits pointing downwards and her mouth facing her master.
“It seems that lady luck says that you suck me off first. Come here.”
He operates a remote that causes a motor to drive the box towards him, until her mouth moves onto his cock. With her head locked in place, the girl can’t adjust her position and the master has to move the box into the right spot. She dutifully gobbles him up and massages his cock with his tongue. Despite her best efforts, her master eventually gets bored and rotates the box further until he reaches her pussy, which he can barely enter, with her body compressed inside the box and the plug in her ass taking up most of the remaining space in her guts. Ignoring her groaning, he just pushes hard enough until his cock is fully buried in her tight pussy.
After a while, he pulls out again and then rotates the box a bit more until her giant tits protruding out of the box are right in front of him. Despite her uncomfortable posture, she enjoys having him fondle her nipples, which eventually harden and extend from her giant spherical tits. She jumps in surprise when she feels a sharp pain in one of the nipples, but soon relaxes after the initial shock. Over the months at the institute, her nipples developed quite masochistic tendencies to the point that she loves having masters inflict pain on her nipples. Every needle poking through her flesh results in moaning emanating from of the box. While her master initially enjoys the slow torture, he has to speed up, as the aroused girl in the box starts to eject milk from her breasts.
Once every nipple is adorned with 10 needles, he attaches a ring between each tit and its needles and turns her around, so her tits are pointing downwards again. This allows him to attach a metal bucket to each ring, which starts collecting sister Mary’s milk. Her pussy doesn’t stay empty for long and he jams a huge 25 cm (9.8 inches) toy inside. It takes him quite a while until he manages to get it in. Once he manages to cram it inside, he switches it on and it starts to vibrate violently. However, this seems to do the trick, as he can soon after hear moaning from the box and more milk trickling into the buckets. He puts his cock into her mouth again and leans back.
“Get to sucking, my dear. This is a two hour drive. I’ll switch off the toy when we are there, but if you manage to fill the buckets, I’ll switch it off earlier, hehehe.”
It turns out he underestimated his slave, as 1.5 hours later, both buckets start to overflow. However, when he is about to switch it off, she says that she doesn’t mind and that she can handle the vibration. As a reward for her good behavior, he removes the lid once they are at the airplane, so she can unfold herself and stand up, allowing her to walk around the private jet that she was so curious about. However, she still has to wear the board around her tits and the buckets full of her milk dangling from the needles through her nipples. After strolling around the airplane twice, her nipples start to hurt and they board the plane, where her tits are finally released.
For the flight, her master has invited 20 friends who get to enjoy the eighteen-year-old for the entire flight. But it turns out that she enjoys them even more. After four hours, every man’s balls were drained, including the ones of the pilots and a friend’s dog who never got to fuck a human before. For her efforts, they offer her a 30-minute break to look out the windows and to visit the cockpit, which she promptly accepts. But after 15 minutes of satisfying her curiosity, she prefers to satisfy her bodily desires and resumes fucking the men.
When they land in Asia, she is put back into her box and driven to the institute, where she is greeted by father Tian, who leads her to her chamber. It has luxurious furniture, with wooden frame ornamentations, exotic plants, and walls decorated by fans and ancient paintings. Sister Mary is mesmerized by the beauty of a culture that is so foreign to her.
“Sister Mary, your seven days with us are already completely booked out. We have the same schedule that you are used to. You will receive your first master tomorrow at 9 o’clock. As an arriving exchange sister, you have the right to request sex with the father of the institute. Do you wish to claim your right?”
“Yes, father Tian, yes, yes, yes!”
Just like father John, father Tian is a tall muscular man, with a giant cock that sister Mary eagerly sucks into her throat. She takes him into every hole and comes many times over. Once she has swallowed his fourth load, the session is over.
While she is still stretching out on her bed after a great fuck, he gets up and opens a second door in her chamber, whereupon her foal is trotting inside. Surprised by the little guest, she quickly gets up and hugs her little baby, which starts sucking on her tits.
“You can finish feeding the foal in this room, but in the future, please do it in the stable outside.”
“Stable? Father Tian, did my stallion come, too?”
“No, only the foal, because it is imprinted on you. But don’t worry, we have horses here as well. Have a good night.”
The next morning, she is greeting six masters at once, of which only one spoke English. Luckily, she soon finds out that translation is not required as long as she eagerly pleases any cock that she touches. After swallowing all their loads and letting them fist her holes for a bit, she is let outside to find a huge horse, just like her stallion at home. Without much hesitation, she strokes and licks his cock until it grows to a 45 cm (17.7 inches), which she pops in her ass.
Moments later, the crowd is cheering at the tiny girl getting ravaged by the massive member. The masters take turns prodding her stomach, feeling the horse penis bulging out the front of the girl’s stomach.
Enjoying all the fascination of the masters, she tries to put on a show and whistles for the foal, which walks over to her mother, unconcerned about the ass-destruction happening on the other side, and starts drinking. The audience gasps loudly and is taken in by the spectacle. Once they see her orgasm, they start jumping around and applaud the little girl. After draining the stallions’ balls twice with her ass, she pulls him out and gathers her guts contents in a bucket to be downed in one go.
For the next two days she barely had sex with a human, as every master wants to see the 18-year-old girl get fucked by horses. In her own institute, fucking her stud was one of many various activities. As a result, her stallion only came so many times that he was out of cum at the end of the day. However, during her stay in the Asian institute, her well trained holes proved troublesome for her, as exclusively fucking a horse drained him so quickly that she was not able to wring another load out of him by lunch time. Therefore, they brought in a fresh horse in the afternoon, which was a lot for sister Mary to swallow. In the last hour, she is close to vomiting it all out, but keeps fighting through to the end, due to her promise to not disappoint father John.
Her tenaciousness pays off, as on the last five days, enough masters had seen the show and now wanted to fuck the girl that had entertained them so much. In those days she also got to meet sisters and brothers of the Asian institute. Sister Mary was enthralled by their immaculate porcelain like skin and thick and glossy black hair. While most brothers are as muscular as the ones at home, a few of them have more graceful and delicate bodies, a variety that she enjoyed to the fullest.
However, under the skin, everyone is just the same, with massive cocks, huge loads, big tits, and infinite horniness. Sister Mary indulges in endless orgies with countless orgasms and bountiful people to please. One thing that she enjoyed the most in the Asian institute are the enthusiastic crowds that appreciate and reward her efforts with applause and marveling gasps.
But time flies when having fun and when the week is over, she is put into a new box to be shipped to her next flight. This time, her legs are locked behind her head and a box encases her torso, wherein her tits are again extending out through openings in front of the box. However, the box only reaches up to her neck and down to her waste, keeping her head and her pelvis exposed.
This time, her master does not torture her tits, but her ass, by forcefully inserting her tail plug. With her body folded onto itself, her intestines are pushed together and routed differently. As a result, the toy keeps hitting her inner walls, when her master tries to insert it in her ass. The box does not allow her to move her pelvis, so all she can do is change her guts by breathing and by screaming if the toy hurts her insides.
After 20 minutes of trial and error, the toy is finally fully inserted. Sister Mary breathes a sigh of relief, but groans in pain, when the master forcefully pulls it out again. An hour later, her intestines have properly aligned so that the insertion can be done relatively painlessly, at which point the master stops having fun.
Next, he attaches a strap to a ring on the backside of the box located behind her ass and adjusts its length so that a hook at its end barely reaches her pussy. Afterwards, two further straps are attached to her nipple piercings, with their length adjusted such that they also barely reach her slit. With his preparations finished, he inserts a conically shaped dildo into her compressed pussy, which inadvertently gets pushed out due to its shape. Using his knee, he keeps forcing the dildo inside until he can manage to attach the three straps to its side. Once the straps are connected to the dildo, he keeps tightening them, which increases the pull on her nipples and the toy.
Sister Mary tries to be silent, but can’t suppress her groans of agony, when the pain in her nipples becomes too much to bear. Now that he reached the desired tension on her tits, the master looks into the eyes of his slave and watches her facial expression change, as he slowly removes his knee from the toy.
With the support of the knee gone, her pussy involuntarily starts pushing the toy out, increasing the pull on her tits. Sister Mary’s groans become louder trying to deal with the pain in her nipples. Her own pussy is betraying her by pushing out the toy and therefore torturing her tits. However, the toy is too deep inside of her to be fully pushed out, lodged in place by the straps to her breasts and the backside of the box.
Once he makes sure that sister Mary’s pussy is inflicting enough pain on her nipples, he presses a button and the toy starts to vibrate.
Her groaning and sobbing are promptly silenced by his cock in her mouth. In the next hour, she manages to drain his balls two times. But much to the surprise of her master, she still managed to come about five times herself. As reward, he lets her decide, whether the toy should keep vibrating for the rest of the ride. To his disappointment, she asks him to keep it switched on.
On the flight, he has to admit defeat again, when sister Mary again manages to please everyone on board before they eventually land in India.
Father Kama welcomes her and shows her to her new chamber, which is decorated with marble walls, beautiful carpets, intricate gold ornamentations and cushioned furniture. The pillows feel so comfortable to hold onto while father Kama plows her in the new bed.
Like in the previous institute, she spent the first two days mostly getting fucked my monstrous horse cocks, filling her to the brim with cum. But afterwards, she gets to fuck a lot of the masters.
She was pleasantly surprised by how friendly many of the masters here are, how many stories she got to hear and how much she connected with them on an emotional level. Getting brutally fucked by a man after befriending him, added a naughtiness that she enjoyed a lot. It also seemed to her that she experienced sexual domination a different spectrum. One moment, she is requested to dominate a man or breastfeed him in a motherly manner and an hour later she gets destroyed by an avalanche of huge cocks. Oh, she had so much fun!
But alas, the week is over and she is put in the next box for her third flight. The box has a long narrow portion that houses her legs with leather straps that hold her legs in a split position. The narrow portion is connected to a flat portion that houses her upper body, with her tits extending out the front and her head poking out at the top.
To each of her nipples is attached a bucket with a hole in the bottom that is connected to a tube. The first tube leads to her pussy and the other tube is inserted into her ass, wherein both tubes are attached to tight rubber pants around her crotch.
Once the car sets off, her master reveals a big jar of cum above her and opens a valve causing the liquid to slowly drip into the buckets.
“These are 10 Liters (2.6 gallons) of horse cum that will drop into the buckets at a rate of a bit over 8 ml per second. That means that in 20 minutes, the jar will be empty. Do you feel the weight on your nipples? Not easy, right? But the buckets are not filling up yet. It will keep draining into your ass and pussy, which can help accommodate some of it. But once they can’t take any more, the draining stops and it accumulates in the buckets. Let’s see how well trained the holes of a level 9 slave are.”
The buckets and the tubes alone have a lot of weight that her nipples have to support, but the pouring cum makes it noticeably more difficult. Sister Mary can already feel the cold liquid reaching her crotch. The cum now accumulates in the tubes, adding gradually even more strain on her tits. However, a feeling of pressure on her crotch is still more distracting from the pain in her nipples. A hydrostatic pressure keeps building up until cum starts gushing into her holes. She immediately feels relieve, as the weight on her tits decreasing. As much as she tries, she can’t actively pull the liquid inside, so she just relaxes her body and hopes that her pussy and ass can take in as much as possible.
After 10 minutes of feeling her insides ballooning up, she can sense that her holes will soon not be able to take in more of the heavy liquid. At around 14 minutes, the cum level is rising in the tubes, as nothing is getting into her ass and pussy anymore. She can feel huge pressure inside her body, but can’t let any of the liquid out due to the tight rubber pants. The pressure keeps building up, but what concerns her even more is that the buckets now fill up, pulling down more and more on her tits.
At the 20-minute mark, the jar of cum is empty and about 3 liters of its content has made it into the buckets, causing sister Mary to groan in pain.
“That is quite impressive I must say. I expected it to spill over. I don’t know if your tits can take this for another hour. Let me give you a little bit of help.”
He pulls out two straws and places them into each one of the buckets.
“There is still some space in you, right?”
Without any hesitation, sister Mary quickly takes the straws in her mouth and starts sucking up as much as she can. She slows down after the first liter and needs to take a break after the second liter, but after 15 minutes of slurping, heaving, and belching, the master can hear air sucked through the straws. Sister Mary lets the straws drop from her mouth and throws her head back in exhaustion. The master is stunned.
“You actually did it? I did not expect that. I’m honestly impressed. You know what? Since you managed to get all the cum inside of you, I think I can let you out of the box for the rest of the ride.”
He turns two valves at her rubber pants, closing the opening to the tubes, allowing him to remove the tubes, with her wearing only the closed off rubber pants. Then, he opens the box and lets her come out. Her stomach is bloated like a balloon bulging to all sides.
“That is almost 10 liters of cum inside of you.”
“Can I lay down, master?”
“Let’s add one more load, and you are free to rest.”
She catches her breath and blows him until she can add another load to her collection, whereupon she can finally lay down and falls asleep.
When she is woken up at the airplane, she is allowed to hurry to the bathroom, where she voids liters of liquid from her body. Afterwards, she is even allowed to clean herself in the warm shower of the private jet. Once she steps out, she is already yearning for more cocks, which her master’s friends happily provide.
In Africa, she is fucked by Father Samedi in her new chamber with beautiful curtains, plants, and furniture having the rarest wood grains. While choking on father Samedi’s big cock she looks at the marvelous fur decorating the floor and wonders what animals they are from.
As usual, sister Mary is almost exclusively fucked by horses in the first two days. One horse has a slightly larger cock with a length of 47 cm (18.5 inches). The two extra centimeters cause her a lot of agony, which she manages to hide for most of the time. She ignores the large bulge below her ribs and keeps smashing her ass into the horse. She even manages to get herself off and gives the same show that she did in the other two institutes, yielding the same applause.
The size mismatch went unnoticed until father Samedi notices her lying in the fetal position in her bed by the end of the second day. After inquiring about her wellbeing, he apologizes for the mishap and has her checked by a doctor, who concludes that she is bruised, but suggests resting for a day. But the girl declines.
“Thanks doctor, but I can’t do that. Father Samedi, there are masters that want to see me tomorrow, right?”
“There are, sister Mary ... ”
“I won’t disappoint them then. I can serve them tomorrow. But, doctor, can you give me something against the pain? Ugh, that was a large horse cock. Dear me, I wonder if a level 10 sisters can take even a 50 cm (19.7 inch) cock in her ass. I wouldn’t know how. But my inability is not the fault of the masters, so let’s give them a show, hehe.”
Father Samedi smiles and instructs the doctor to do as she said.
The pain medicine works great as she is in perfect shape the next day to fuck all the masters with enthusiasm and pleasure.
However, in the afternoon, she is again led to the stable, where the last two days the stallion had hurt her so much. She follows along calmly, but is nervous inside. Just because the medicine took the pain, does not mean she has healed. Would the horse damage her this time? Should she try it anyway? She must, for father John. She promised.
Once inside, she is surprised to see father Samedi who asks the master and sister Mary to sit down.
“Sister Mary was supposed to get fucked by the horse for you, mister. But I made a mistake, which damaged her insides. I apologize for my error and hope that I can make it up to you by offering you our level 10 sister as a substitute, obviously free of charge.”
“Ah man, that sucks. I wanted to see the young girl get fucked. But a level 10? Free of charge? I think I can forgive you old man, hehe.”
Father Samedi claps his hands and a woman enters the stable walking slowly with the elegance of a panther. Sister Mary notices a sparkling diamond collar around her neck and a 1 meter (39.4 inches) tail dragging along the floor. However, the first thing that caught her eye were her gigantic 5000cc tits, forming two majestic spheres swinging with every step. Her smooth black skin creates a mesmerizing contrast of light and shadows, further accentuating her perfect body. Oh wow, look at her huge butt, it’s muscular, yet soft. The skin is firm, but ripples with every step. Sister Mary feels the urge to bite it, but quickly dismisses the silly thought. The woman stops in front of the master and kneels down.
“Greetings master, I wish to serve you.”
Before the master can say anything, father Samedi addresses her.
“Sister Anaisa, please take your stallion in the ass.”
“You know I love that, father Samedi.”
Father Samedi then turns to the young girl sitting next to him.
“Sister Mary, you have performed dutifully, despite my error. Yesterday you were wondering whether a sister can even take 50 cm (19.7 inches) horse cock in her ass. Allow me to make it up to you by giving you the opportunity to observe our level 10 sister Anaisa.”
Sister Mary watches carefully as sister Anaisa approaches a monster of a horse that sports a throbbing 50 cm (19.7 inches) member. She puts the head in her ass and steps a bit forward, allowing the stallion to only thrust into her about half of the shaft. She closes her eyes and gradually shifts her body by arching her back and pulling up the left side of her upper body. After a few small steps backwards, almost all of the horse’s cock disappears in her ass. Then she takes a few breaths, adjusts her body a bit more and resorts to small breaths with short intervals in order to keep her diagram at an elevated position. Now she takes one more step backwards and everyone in the room can hear the horse smacking against the big ass of sister Anaisa.
Sister Mary is cheering and walks up to her to get a better view, shaking her head in disbelief. After watching her get fucked for a while, sister Mary gets closer and starts caressing and sucking on the tits of the ass-fucked girl. After a while, her eyes roll up and she comes with the entire horse cock buried in her guts. Sister Mary is awestruck and excited.
“That was amazing! What a brilliant technique! I can’t do what you just did ... but, maybe I can try the horse from yesterday. If I apply your technique ... it should be possible. Father Samedi, may I ask that yesterday’s horse fucks my ass?”
“It’s what your master had originally requested anyway. I’ll allow it.”
Under the guidance of sister Anaisa, she learns to adjust her body positioning and breathing while carefully backing into the horse fucking her ass. As the cock goes deeper, she can feel her body resisting further insertion, but he is not fully inside of her yet. Sister Anaisa is caressing her, trying to calm down the girl that is trying to suppress her groaning in order to not lower her diaphragm.
“Don’t push yourself too hard. If the horse hurts you again, you may be out of order for the next days ... or worse.”
“I know, sister Anaisa... but I’m so close! I can do it!”
“Are you sure?”
“... no, but I won’t stop trying.”
A small smile appears on sister Anaisa’s worried face and she kisses the sweaty forehead of the brave little girl. Then, she calms down the horse a bit, which slows down his thrusting until he eventually stays still. The girls give each other a nod, and sister Mary pushes backwards with clenched teeth. After pushing for a few seconds, she needs to catch her breath, while she shakes her head over her lack of success. Without daring to look back to check, how much distance she is still missing, she resumes backing into the horse. After each failed attempt, her resolve and confidence wanes.
Suddenly, she gasps when she can feel the stallion’s groin against her ass. For a moment, she manages to smile at sister Anaisa, but the happy moment is promptly interrupted when the horse resumes thrusting into the 18-year-old’s ass. After feeling his entire shaft buried inside of her, he no longer wants to stay still and decides the fuck the tight hole.
Sister Anaisa checks on her and upon seeing her determined face decides to return the favor and stimulates her nipples until sister Mary succumbs to her victorious orgasm.
Under applause, the girl pulls out the gigantic horse member and is led back to her chamber, where the doctor confirms that the stallion did no significant damage.
The final days in the African institute were filled with gangbangs and lavish orgies with her rarely ever fucking only one person. She loves submitting her master’s demands and enjoys how they go wild, tossing her around drilling her senseless. However, many orgies eventually end in laughter and cheers when they realize that the little eighteen-year-old girl can go longer than all those men with drained balls lying exhausted on the floor.
Nonetheless, the week eventually ends and she has to say goodbye to the masters of Africa. When she arrives back home, father John welcomes her and commends her about the praise he had received from the three institutes, especially from Africa where she bravely endured the large horse. Her heart jumps with excitement hearing that she has done well for her beloved father John and cries tears of joy when she gets to fuck him upon arrival.
In the next week, she settles back in the routine of her home institute. Having missed her dear stud, many masters allow her to fuck the stallion, which she can now easily take in her ass even with a stuffed pussy.
One morning, she is led outside the stable where she sees three masters with outdoor clothing and guns holstered behind their back. Without much explanation, she is instructed to attach leather straps to her arms, legs and torse, which are tied together until she is frog tied with her bent legs spread apart and her arms behind her back. In this position she is laid face down on a bench, allowing her stallion to penetrate her ass. Once his cock is fully inserted to the hilt, sister Mary is attached by the leather straps to a saddle on top of the stallion. As a result, she finds herself belly riding as an undercarriage under the belly of the horse with its cock fully buried in her ass.
One of the men jumps up on the saddle and instructs the stallion to walk forward. After a while, they switch to trotting and sister Mary can feel the cock in her ass swaying from side to side. Next, the horse is cantering and she can feel the stallion digging around in her guts. She can handle it, but is dreading what she knows to come next. The man squeezes his legs and the stallion starts galloping. The hind legs of the horse are now moving in parallel, which causes the cock in her ass to quickly thrust in and out. At the same time, the disoriented girl can only see ground passing by below her, not knowing where the horse in her ass is going. Unconcerned with her screaming, the master rides a few rounds until he goes back to the other men.
“What do you think gentlemen? It seems the horse can move fine, right?”
“Yeah, and the girl is screaming, so she is still alive, haha. We can set off soon then.”
“Masters, what do you mean? Where are you going? Are you taking me with you like that?”
“Yeah, we are taking you with us to a hunt.”
“What are you hunting, master?”
“You will see when we get there. Where is the wolf?”
A few seconds later, sister Mary can see her sire brought to them. When she calls for him, he comes over, recognizes his bitch, and licks her smiling face.
The foal had been watching from the side and uses the opportunity of her hanging tits to come over and start drinking, whereupon the men decide to bring the foal with them as well. In order to ensure good milk production, they insert a large vibrator in her pussy and switch it on. Two more horses are brought for the other men and the gang heads out.
At first, sister Mary is screaming, scared to fall off the horse, worried about rocks in their path almost hitting her, or the cock in her ass splitting her in two. But after some time, her worries turn out to be unfounded and she gradually gets to relax, enjoy the outside, enjoy the cock in her guts, the wind on her face, the dildo in her pussy, and the ride with her dear stallion, sire, and foal.
After a few minutes she comes her first time, which continues into more and more climaxes. At some point, the masters let the foal drink so as to not waste the milk that the horny mother is spilling on the ground. A bit later, the wolf seems to pick up a scent and the men follow after in full gallop.
After some time, they reach a dense forest, where the sire eventually loses the scent. The men continue until they reach a grassy clearing and set up a camp. Sister Mary gets a bucket to deal with all the cum her stallion had pumped into her during the ride and then proceeds to fuck her masters until they drop exhausted into their camping chairs. While they rest, she is to satisfy the remaining two horses and the sire. Sister Mary feels a sense of pride when she realizes that her stallion, who she can already handle so well, has the largest cock of the three horses. But she keeps the thought to herself and dutifully tends to the animals.
Once she is done, they instruct her about the hunt.
“We asked the institute to release five wolves into this private land to hunt. We have tracked them down to this forest, but now we have to lure them out with some bait.”
“What is the bait, master?”
“You are, sweety. You will go out with that foal of yours and look for them. And once you find one or it finds you, hehe, you hold it in place and send the foal back to us.”
“... but, how can I hold it, master?”
“They are wolves from the institute, so you just gotta keep ‘em busy. I’m sure all of them have fucked you already at some time in the past. While you distract the wolf, we can shoot it.”
“Oh no, you are going to kill them, master?”
“Nah, we use tranquilizer guns. Killing them would be too expensive. Alright, but now get going looking for them.”
“How can I find them, master?”
“Make them find you, didn’t the entire squad here give you a lot to drink?”
Sister Mary slowly understands, nods, and sets off into the forest with her foal at the side. After marking her territory, she keeps walking around, trying to get attention. Suddenly, she hears some rustling and turns around to see one of the wolves approaching her, sniffing the air. Sister Mary sends the foal away and gets on all fours, trying to lure the animal closer. The wolf seems uncomfortable and gnarls at the intruder. It takes her a few attempts until she can finally pet him, slowly earning his trust. Eventually, she gets lower, manages to lure his cock out and starts blowing him, which finally calms him down. Once he is ready, she guides him behind her and he mounts the inviting bitch. After taking him in her pussy for some time, she pulls him out and puts him in her ass, all the way until even the knot is inside of her.
He already shot two loads into her when his keen ears hear the men approaching. Sister Mary notices that he pauses and quickly guesses that the wolf is growing suspicious. Before he can run away, she quickly clenches her ass as tight as possible, trapping the animals like a Venus fly trap. He can almost pull out before she manages to grab his hind legs, pulling him deep into her ass. With every passing second, the lust in the beast transitions to aggression and he starts growling at the temptress. Sister Mary now has to fight an animal larger than her and avoid its attempts at biting her while she is holding onto it with her hands and ass. He wants to go right for her leg, when a shot gets fired and after a faint howl, it collapses to the ground. Sister Mary lets go of its legs and lies next to him, catching her breath, still with his cock in her ass.
The men hogtie the wolf, put it on their horse, and return to their camp after instructing sister Mary to get the next one. Her legs are still trembling as she stands there with the foal next to her, watching them leave.
She keeps looking and eventually finds two more wolves to seduce and fuck until her masters can shoot them down. Only two more to go.
However, her heart skips a beat when she sees one of her grown cubs slowly approaching her. In the last few weeks, they had grown apart a bit, but the wolf is longing for familiarity after being alone in the forest. He joyfully trots to his mother and licks her face. Sister Mary indulges for a while in the happiness that they feel for each other, postponing as long as possible her eventual betrayal against her little baby.
Unlike with the other wolves, she takes her time, caressing his fur, holding him close, and gently sucking his cock. Only after she swallows his first load does she send her foal to the men. After 15 minutes of enjoying some intimate time with her cub, she can feel that he is startled by approaching footsteps and starts holding him down. This time, the wolf does not growl or snap at her, but just howls, giving his mother confused looks when she stops him from getting away. Eventually she turns her face away until a shot echoes through the forest, silencing the animal.
“What the fuck is wrong with this crybaby? He didn’t have any fight in him. How disappointing!”
“Master, this is ... this is one of my cubs. I nursed him when he was a baby. That is why he trusted me.”
“And you betrayed him! That’s hilarious, what a terrible mother! Now get your son’s dick out of your ass, so we can tie him up, it’s getting late.”
The men are still laughing and imitating her cub’s howling while she watches them ride away. Sister Mary consoles herself by feeding her foal for a bit, but her tits are eventually drained. Her milk production requires her to eat a lot and she hasn’t eaten in a while. It is indeed getting late.
Eventually, she finds the last wolf, but he acts differently. Instead of standing at a distance in mistrust, he approaches her confidently. Does he know her? He is none of her kids. Wait, he is not going for her ... he is going for the foal? Oh no, he wants to kill the foal!
She pushes the foal away, screaming for it to run and sprints towards the attacker. When they collide, she is pushed to the ground by the heavier enemy, but she manages to hold onto the wolf’s collar. While he drags her along the ground, she keeps screaming at the foal to run, which is sprinting away in full gallop. Once the wolf realizes that it got away, he turns towards the mother instead. He quickly spins around a few times, rotating her wrist until she has to let go of the collar. The beast is angry and growls at the little girl.
Thank god, the foal managed to escape, but while she does not regret saving the foal, she has no plan on how to survive this fight either.
Maybe she should get some weapon? Is there anything on the ground? A stick, grab it, but don’t lose eye contact. Got it, what now? What is he going to do? Where did all these wolves bite her during sex? The neck! Get the stick in between your neck and him, hold it with two hands, maybe you can divert his bite. But he threw me to the ground so easily. I need to stand more firmly. Walk to the tree, get it behind your back, but don’t look away. What’s the plan?
Too late.
The wolf jumps at her and through sheer luck, she succeeds in catching his bite with the stick. She manages to hold him off with the tree on her back, but he starts clawing at her with his paws. However, sister Mary has legs as well and she manages to kick the wolf between his legs onto his massive balls. With a loud howl, he lets off her and lays down for a moment. In this short opening, sister Mary pushes her stick through his collar, hoping to get a better grip. However, the wolf starts snapping after her, causing her to lose hold of it. The collar now has the stick instead.
Having just disarmed herself, she panics and runs away. However, her large tits don’t allow her to run for long so instead she tries to hide between two rocks, where she finds herself in a dead-end. When the wolf runs around the corner, she braces herself to fight to the death with her bare hands. He jumps and she can only look away with raised arms.
However, the wolf howls and is stopped in his tracks. The stick is still threaded through his collar and has miraculously wedged itself between the two rocks. He is stuck! Quick, trap the stick somehow. Sister Mary picks up heavy rocks behind her and places them on the stick, burying both ends below them.
When the men find her, they see an exhausted girl with bleeding bite and scratch marks sitting next to her prey. The masters are perplexed.
“What the hell happened?”
“The wolf tried to kill my foal, but I stopped it, so he attacked me, master.”
The men carefully approach the wolf’s body and shoot it when they realize that he is still alive. The foal walks past them and licks the wounds of her mother, while the men look at the little girl in disbelief.
“Wait, you fought the wolf and won? Without guns? How is that possible?”
“I did not plan to defeat the wolf ... I only thought about saving him ... look, master, the foal is alive ... you see? I’m a good mother ...”
The three men are speechless and drop their guns in order to help the sniveling girl up. Afterwards, they put her on their horse and bring her back to the camp, where they clean her wounds and give her their food.
“Listen, kid, can we keep that incident with the wolf between us?”
Sister Mary pauses for a second, but gives them a nod.
“Thanks, you are a real trouper... but the thing is, if we don’t ride back with the horse cock in your ass, it may raise suspicions ... soooo, is it ok if we hang you under the horse again? We will go slow this time, I promise.”
She pauses for slightly longer, but nods again with a small smile.
On the ride back, her body aches, but surrounded by her many family members, her soul enjoys a fleeting moment of peace.
