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).
IV. The level 3 of sister Mary
Over the course of 9 days of being level 2 (or a total of 19 days), sister Mary manages to hit all criteria for level 3 and requests to be tested. However, to her disappointment, father John did not visit her until an hour after her request.
“Is everything ok, father John? It appears you are quite busy.”
“I had to finish another test just now. I am proud to say that our sisters are progressing so fast. Well, sister Mary, you requested to be tested for level three. You need to be able to insert in your ass the widest toy, the longest soft toy, and the longest hard toy we have provided. Furthermore, you have to show that you can insert the widest and longest toys for your pussy.”
Despite struggling with most of the toys, sister Mary shows off her skills with a smile. After she passes all the tests, father John exchanges her green ribbon with a blue one. Before he can say anything, sister Mary immediately claims her right to have sex with her beloved father John. Getting fucked harder than by any of the masters, she is rewarded with a massive load of cum that she eagerly swallows.
She is subsequently escorted one level higher, to her new chamber. Similar to last time, father John brings a blue box with five sets of toys.
Father John: “In order to reach level 4, you have to be able to insert larger toys in your ass and pussy. This first set contains four butt plugs. They all have a length of 17 cm (6.7 inch), but increasing diameters starting from 20 cm (7.9 inches) in one cm steps to 24 cm (9.4 inches), which is required to pass the test. The second set has six flexible butt plugs with a length starting from 23 cm (9.1 inches) to 35 cm (13.8 inch). The third set has five rigid dildos, one with a length from 21 cm (8.3 inches) to 25 cm (9.8 inches). The fourth set comprises dildos for your pussy. The smallest has a circumference of 21 cm (8.3 inches), the largest a circumference of 25 cm (9.8 inches). The last set has a single dildo for your pussy with a length of 24 cm (9.4 inches). You have to be able to fully insert all five toys for level 4.”
Father John: “As a level 3, masters can start fisting your pussy and you will wear a clitoral hood ring. Now, prepare yourself, this will sting a bit more than last time.”
She gets worried about the ring, but only really understands what he meant, when a needle approaches her crotch. Before she can form a sentence voicing her objection, she is screaming when the needle pierces through her flesh. Neither does she stop while the ring is inserted into her clit. Still in shock, she wants to crawl into a fetal position, but bravely stays seated on her bed, resorting to sniffling.
“Congratulations, sister Mary. You are officially a level three sister.”
She tries to muster a smile, but is still struggling with the pain radiating from her pussy. Father John starts probing her breasts.
“It seems your implants have healed well already. Let’s see how well they perform.”
He pulls out a gun shaped device and shows it to sister Mary.
“This is a heating device. It can generate a short burst of heat energy at a focal point a few centimeters in front of it. Let me show you.”
He abuts the device against her left tit and pulls the trigger. The gun beeps for a second and sister Mary is shocked to see that her breast is swelling.
“Your breast implants are mostly filled with liquid hydrocarbons, which have a low density. As a result, we will be able to increase the implant size without adding as much weight as a saline filling would. Furthermore, we have added small amounts of liquids with low boiling points such as dichloromethane. It stays a liquid at body temperature but becomes gaseous at slightly higher temperatures. A foaming agent in the implants allows for an even distribution of the gas. Each shot increases the volume of your implants by about 100cc.”
He proceeds to increase the size of her other tit.
“Any pain?”
Sister Mary is still in shock, trying to process what was done to her body. A bit frustrated, father John has to repeat his question, which finally catches her attention.
“I only feel a stretching sensation, father John.”
He proceeds to apply another shot into each of her breasts.
“It keeps stretching. Please, father John, I am scared.”
With the third shot, she starts to feel some heat in her breasts and with the fourth shot, she starts to whimper. Her tits are now hurting and she begs him for mercy. Disregarding her pleas, he applies a last fifth shot into each of her breasts.
“There is just enough boilable liquid for a fifth shot. The size of your tits has increased by about 500cc each. That means we are at 1500cc each.”
“It burns, master John... are they going to stay like this?”
He does not pay much attention to her worries and inspects her tits for size and possible damage. They work perfectly, just as planned.
As the heat starts to become more noticeable, she becomes increasingly anxious. Seeing her panic, he rolls his eyes and takes a glass of water from a table and slowly pours the water over her tits, which start to shrink again.
“The gas will turn back to a liquid once cooled, for example with some cold water. The mixture in your implants is pretty stable. So, we can do this as often as we like.”
Sister Mary, breathes heavily but manages to compose herself, with the uncomfortable breast expansion gone. Once she is calm, he explains more about her new life.
“As a level three, you will get a bigger bed, a bigger mirror and a carpet around your bed.”
Slowed down by her painful crotch, she walks over onto the soft carpet and looks at herself in the mirror, examining the new jewelry in her clit. Despite her soreness, she smiles at father John with pride, who looks at her with slight concern.
“Sister Mary, you have made a lot of progress in little time just now. Stretching your ass and pussy comes easy at the start, but will become more difficult. Be careful not to injure yourself from now on.”
As expected, she is enthralled about his worries, but he does not care enough to tell her that she makes him less money when she is injured. Keeping her in her naive belief, he only bids goodbye and leaves her in the room.
Since it is already evening, she performs her physical training and afterwards tries all the new toys. However, she finds that she cannot progress any further yet. In the face of such defeat, she insists on sleeping with her widest butt plug. It keeps her awake a long time, but in the end her stubbornness prevails and she can fall asleep.
The next morning, sister Mary is a bit shaken when she recognizes the first master of her new day. But she quickly composes herself and greets him.
“Good morning, keeper of my tits, how may I serve you?”
“Aww, she remembers me, how sweet. And all it took was modifying and abusing your body. Let’s get started with your ass. Bring me the biggest toy you can fit in your ass.”
“I’m still struggling with the 22 cm toy, keeper of my tits.”
“I like struggling. Get to it.”
After a few tries, she manages to work the entire toy up her ass. Disregarding her achievements in stretching her ass, he orders her to stand up and turn around. He binds her arms behind her back and attaches her cuffs with a chain to her butt plug, forcing her to arch her back. Due to her posture, she needs a lot more time blowing her master until his cock is hard and dripping in her saliva.
He pulls out a rubber band and winds it around both her nipple piercings, tightly connecting both her nipples. He is pleased to hear her breathing getting heavier, indicating to him that they are already hurting. Just to be sure, he squeezes her nipples between his fingers causing her to scream out loud. Satisfied with his work, he sits on the bed.
“Put my cock between your tits and give me a nice no-hands tit fucking.”
She waddles with her arched back and stretched ass over and kneels down between his legs. After a lot of trying, she manages to get her tits around his cock. However, when she tries to move her tits, she notices that the chain between the cuffs and her butt plug does not allow her to move her upper body a lot. So, she has to resort to using her legs to move up and down.
After 5 minutes of squatting to please her master, she has to take a break and catch her breath.
“Just a moment, keeper of my tits, my legs are giving up.”
“Don’t worry, let me continue for you, my little slave.”
He firmly grabs her nipples and forcefully moves her tits up and down on his cock. Sister Mary weeps as she tries to move her tired legs in the rhythm that her master is pulling on her nipples. Once he is satisfied with the pace, he lets go. He has to torture her nipples a few more times, as she struggles to keep the pace. When he finally comes, she throats the entire cock to get some leverage other than her legs. She makes sure to swallow everything and can finally collapse onto the floor once her tits slide off his softening cock. She is breathing heavily, chest heaving, with her nipples still connected. Her master’s only physical activity was to come hard from her boob job.
“Good job. I don’t know about you, but I am spent. How about some reinforcements?”
He grabs a device with a microphone.
“Bring her in.”
Moments later, the door opens and a woman enters the room.
“Greetings master. I am at your service.”
He gestures to sister Mary, who is still lying face down on the floor, with her arms bound behind her back.
“Help her up and sit her on the bed.”
Sister Mary barely manages to get back up on her shaky legs and drops onto the bed, without any disregard for the toy stretching her ass to her limit. Sitting on the bed is still more comfortable than the hard floor.
“Thank you very much, sister...?”
“Sister Robbie.”
“Thank you, sister Robbie.”
She looks up and sees a tall beautiful woman smiling at her. Still exhausted from the exercise, it takes her a while to realize that the woman has a massive cock.
“Sister Robbie, ... you have a ... penis?”
Her master laughs, after having eagerly awaited her reaction.
“Haha, you seem surprised. This slave here is transsexual. Born a man, but made to a woman. This place really has everything now doesn't it! I love it. Well, go on, suck it!”
Sister Mary has to bend down far to grasp the head of her cock with her mouth. She manages to suck it into her throat while it is still soft. But once the shaft starts to swell, she can barely fit it into her mouth. After working for a few minutes, she stares at a glistening 30 cm (11.8 inch) cock. Almost as large as the one of her beloved father John. Sister Mary’s initial bewilderment gradually fades and turns into curiosity, then turns into desire. She wonders how much she can take. Her master makes himself comfortable on a chair and orders sister Robbie.
“Fuck her face.”
Without hesitation, sister Robbie takes sister Mary’s head and shoves her cock as deep as possible into her mouth. Sister Mary gets to breathe only sporadically while having her face raped. After a few minutes of violently stretching her throat, the master orders sister Robbie to come. She pulls out of sister Mary’s coughing throat and shoots massive ropes of cum into her mouth. She has to take a big gulp in order to swallow it in one go. Too bad, sister Mary was curious about getting fucked by that huge cock. Her chance seemed wasted on the blowjob.
Their master does not give them much time for a pause and orders sister Mary to lay on her back.
“Now, fuck her pussy.”
Sister Robbie seems not fazed by the order and proceeds to place her still hard cock against sister Mary’s slit. She still has the toy in her ass, leaving little room to fit the enormous cock in her pussy. Sister Robbie is pushing, but can’t get in. The large head rubbing against her clit is creating an anticipation that drives sister Mary wild. She wiggles her pelvis trying to get a better angle. When it finally pops inside, the cock can only slowly travel inside, barely scraping by the big toy in her ass. Sister Mary just stares with wide open eyes while processing her body being stretched so far. After sliding in about two thirds of its length, sister Robbie’s cock hits the cervix, causing sister Mary to utter a small whimper. Sister Robbie does not waste much time and starts thrusting.
As the toy slows down the movement inside the tightened pussy, she rolls sister Mary to the side and grabs her thighs as leverage. Sister Mary gets her pussy pounded with no mercy. But she does not mind. It feels amazing accommodating such a massive tool inside of her. Keep going, she can take it. Her body responds and she convulses under a massive orgasm. Sister Robbie is ordered to pull out and to serve her another load of cum. However, there is no rest in sight for her still.
“Remove the toy from her ass.”
Sister Robbie removes the chain from the toy, pulls out the plug, and shows it to the master, asking what to do with it.
“Shove it up your own ass.”
Without hesitation, she pushes the toy against her ass and buries the toy in her ass in one swoop while still standing. Sister Mary looks at astonishment at the ease in which the plug vanished in her ass. That is the first time that she notices that sister Robbie wears an orange ribbon around her neck. Maybe she is a higher level than herself. Maybe she...
“Now fist her ass.”
What? Sister Mary still has not fully registered the order when sister Robbie’s fingers are already pushing against her sphincter. In a matter of seconds, four fingers are inserted in her ass. However, when she approaches the knuckles, her ass resists further entry. Sister Robbie does not pause for long and gradually pushes with more force. They need several tries until the knuckles finally pass her sphincter. After all this pressure, the fist forcefully slips in and punches her in the gut. Sister Mary lets out a groan and wants to reach for the arm in her ass with her cuffed hands. But Sister Robbie would not budge.
“Don’t disappoint our master, sister Mary.”
She contemplates for a second and lets go of her arm, sobbing a defeated “ok”. The master laughs and instructs sister Mary to get on her knees bending forward. With her hands still bound behind her back, she has to bury her face in the bed, while getting viciously fisted for several minutes. Eventually, he allows her to stop, however, not to remove her fist.
With her colon burning form all the thrusting, she is then instructed to walk over to her master for a last tit fuck. Walking with a fist up her ass is not easy. She almost falls forwards but was pulled back by sister Robbie’s arm in her ass. The moment she squats in front of her master in order to put his dick between her tits, her legs already start hurting again.
Another pain she almost forgot was the pulling between her connected nipples. She would have been brave enough to not cry. However, when her master pulls out the heating device and proceeds to inflate her tits wrapped around his cock, she pleads for mercy.
The more her tits are expanding, the more her nipple rings are pulled apart. When the inflation is complete, her pleads have already turned to screams of pain. However, the master smiles and enjoys the show. After she has calmed down a little, he turns to sister Robbie and instructs her “Make her make me cum. Hehe”
After a few moments of thinking, she nods and repositions herself for better leverage so she can push. Sister Mary has not even registered the instruction yet and jumps when she feels sister Robbie push her hand up her ass. However, it dawns on her once Robbie starts to push rhythmically up and down. Initially, she can keep pace, but when her legs get weaker, she groans in frustration much to the joy of her master.
“What’s the matter? You have all the choices. You can decide whether you want your legs or your ass to hurt. And if your tits are hurting, it is up to you when you make me cum. I should rather feel sorry for sister Robbie who has to control you ... like a frustratingly unresponsive hand puppet. Now dance for me, little hand puppet.”
She tries her best to give him a good tit fuck, but after several minutes, her legs can barely move. After receiving stern looks by the master, sister Robbie changes strategy from thrusting her arm into sister Mary’s ass to lifting her by the ass. As a result, the titfuck resumes its pace, but under constant screams of pain from sister Mary. Unrelentingly, sister Mary slides her tits up and down his cock, either with pain in her legs or pain in her ass. Eventually, everything hurts. Her master enjoys the good work of sister Robbie and the screaming of sister Mary, which seems to do the trick and she finally gets to swallow his last load for the day. She slips her tits off his cock and her ass off sister Robbie’s hand.
The rubber band is cut off her nipples and she is left lying on the floor. Her moment of rest is cut short when the monitor reminds her to get ready for the next master. After a groan of frustration, she dutifully gets back up on her feet and prepares herself for her next master.
She gets through the day without too much trouble, but her ass stays sore until the evening. Nonetheless, that does not deter her from sleeping with her ass plugged.
From then on, masters occasionally made her have sex with trans women as well. After the oddness of the new experience fades, she enjoys it more and more, but still struggles sometimes with their capabilities. It turns out that they all have massive cocks that seem to generate huge amounts of cum with next to no down time. At one occasion she was gangbanged by six trans sisters and had to swallow 30 loads totaling to about half a liter (17 ounces) of cum. That day she skipped dinner.
Just as she had been told, her progress slowed down. After a week, her ass can take 21 cm (8.6 inches) in circumference and 25 cm (9.8 inches) in depth, whereas her pussy can take 22 cm (8.7 inches) in circumference and 23 cm (9.1) in depth.
However, on the next day she notices a different kind of progress during her training, when she sees that the pumps are filled with milk from her breasts. She announces it to the monitor in her room, not knowing if someone is even listening. To her surprise, 15 minutes later, even at such a late time, father John appears in her room with sister Lottie.
He takes her pumps, glances at them and hands it to sister Lottie who weighs the milk on a scale.
“About 150 grams, father John.”
He nods at her, whereupon she leaves the chamber with her equipment.
“Did you produce milk in the morning, sister Mary?”
“No, father John, only just now.”
“Good. Keep pumping in the future. Here is a set of larger pumps.”
He hands her two large devices that she inspects with a puzzled look.
“Father John, they have huge containers. Is this for my milk? How much milk are you expecting? What is going to happen?”
“We don’t know yet. These are one-liter containers for each of your tits, which should suffice for now. After each pumping session, you place the filled containers in this collection box, where someone will fetch it.”
While he leaves her chamber, she asks one more question.
“What should I do if I produce milk while being with a master?”
“That is up to the master to decide.”
And so they did. The next few days, many masters were interested in her breasts. They sucked on her tits, made her suck her own tits and tried milking them. Initially, she did not produce enough for more than two or three masters a day, but her milk production quickly intensified. After a week, she produces 1.5 L (50 ounces) a day and double the amount after two weeks.
In the morning, the first thing she does after getting up is pumping just to release some of the pressure build up overnight. However, since her nipples strongly react to arousal by ejecting milk, the masters demanded her breasts to be as full as possible. Therefore, she is not allowed to pump more than half a liter after waking up. As a result, her breasts are almost always full and aching to be drained. By the time she receives her first master of the day, her tits are already leaking and feeling so swollen that she begs everyone to milk her.
Not only is she looking for relief, but also for pleasure. Her nipples have gotten incredibly sensitive since she started to produce milk. On top of that she found herself to be constantly horny. With each passing day since her rite of passage, her arousal had been increasing. But the moment she started lactating, she has been experiencing an almost frustratingly high level of horniness, barely quenched by a climax. As a result, she comes several dozen times a day. Her sex drive is barely satisfied by the many hours of sex with the masters. Even when she is alone, she often ends up masturbating.
Due to her horniness, she pushes herself more and more when stretching. It is luck and not caution that she does not cause too much damage to herself. Apart from her own training, she gets stretched a lot with her masters. Some of them like to get drunk and now start inserting their beer cans (circumference of 21 cm or 8.2 inches) and later their beer bottles (circumference of 23 cm or 9.1 inches) into either of her holes. Furthermore, she gets fisted at least once per day by one of the trans sisters. However, she loves getting fucked by their huge dicks and pushes them to get as far as possible. Challenging them so much usually means she has to swallow many loads, or she rather gets to. With every load she is guzzling down, she loves it more. The masters test her by coming on her tits, in her pussy, in her ass. It does not matter; she scoops it up and downs it every time.
Her enthusiasm is tested soon by a group of masters. She is escorted to another chamber, where she is meeting sister Ember again. Just like sister Mary, she also already sports a blue ribbon and enhanced breasts. But they don’t seem to produce any milk, at least not yet? Is she surpassing sister Ember? She smiles at her and makes sure that her milk filled tits are swinging with each step. When sister Ember’s jaw drops, sister Mary skips and grins, radiating with pride.
“Dear lord, sister Mary, what happened to your breasts?”
“I’m lactating. They have already produced liters of milk. Here, look!”
Sister Mary gently strokes her nipple, until streams of milk are shooting through the air. She grabs her breast and guides the stream into sister Ember’s gasping mouth. She turns away fending off the unexpected liquid, but curiously tastes what got in her mouth.
“Heavens me, it tastes like milk, and so sweet. I did not know breasts can do that!”
“Do you think that yours can do that too?”
“I don’t know sister Mary. Heh ... I am not a cow, you know.”
Sister Mary moos, which causes them both to erupt in laughter.
When the door opens, they quickly compose themselves and sit upright. Six masters come into the room and sit down on respective arm chairs, followed by ten trans sisters that stand in a line awaiting orders. After the door closes, one of the men explains.
“Here they are, the two young girls. We have heard that you love getting ravaged by the cocks of these magnificent women. These fine gentlemen and I have decided to raise a small fortune to put you to the test. Which one of you can take more? We will see. Ladies?”
The ten sisters turn the masters in unison.
“Yes, master?”
“Ravage them”
Without hesitation, they go for the pair of girls and pull them onto the bed. Soon after, all of the holes are filled and fucked furiously. Despite their experience and training, they can’t take any of those massive dicks to the balls. Each thrust hits a barrier inside. But the girls don’t mind. The master was not lying: they both enjoy getting plowed so intensely. Their moaning and groaning is interrupted by cheers of the audience when sister Mary’s tits start spouting milk. Both sisters convulse into their first of many climaxes and keep begging for more. The trans sisters soon follow suit and fill their mouths with seemingly endless amounts of cum.
After half an hour, they get a short pause where they suck off all of the six masters, just to jump back onto the bed for more drilling. After an hour, they drain their masters again. By now they are too exhausted to go on top and ask to be fucked laying on the bed. After 1.5 hours, sister Mary’s tits were drained by all her arousal and stopped expressing milk. At the two-hour mark, they feel their holes hurting. After three hours they can’t tease out any more orgasm out of their young bodies. The masters talk with each other and finish their conversation by nodding. The old man stands up again.
“Thank you, ladies, you can rest for now.”
Sister Ember and sister Mary are lying on the bed, out of breath and covered with sweat. They can’t rest too long, as they are told to put butt plugs into their asses. They only have a circumference of 20 cm (7.9 inch), but also a length of 20 cm. When they try to insert the toys, they notice that their guts struggle to accommodate both, the toys and their cum filled stomachs. It takes them so long to insert them into their sore asses that the master continues the event without further waiting.
“How many loads did they swallow?”
One of the trans sisters steps forward.
“I counted 41 loads for the blond one and 43 for the brunette.”
She looks at the other trans sisters that nod in agreement.
“Make it even then.”
Two women walk over to sister Mary and make her swallow two more loads, while she is trying to get the toy in. Their stomachs already felt so full, but with the huge toy inside, they start to feel nauseous. None of them had ever swallowed this much in a single day. But as with any good dish, too much can make you sick.
“Send the men in!”
The door opens and ten huge men walk in. Sister Mary and sister Ember slowly sit up and gaze at the giants walking in. It does not take them long to see that they are hung as well.
“I take it that you have not seen the men of the institute. Level 3 sisters don’t have to have sex with them yet. They might get hurt. However, I did not summon them to fuck you. They just need to provide more cum to swallow.”
Two masters place a bucket between the girls and place a box with weights on the bed.
“Contestants!”
Sister Ember and sister Mary are looking cluelessly into the room, then point at each other.
“Yes, you, start sucking off these cocks and swallow their loads.”
Then, he turns to the men.
“Every time, a contestant has swallowed your load, you take weights from the box and attach one to each of her nipples. This should motivate them to hurry sucking you off. The weights are 50 grams (1.8 ounces) each. So, if a slave swallows, for example, 10 more loads now, each nipple will have a weight of half a kilo (1.1 pounds).”
He turns to the two girls.
“Contestants, this game is easy. You keep sucking and swallowing until one of you pukes into the bucket placed between you. We will need it later, so don’t miss it.”
He smiles with a wink at the two girls, who are looking around in panic trying to understand what is going on.
“The game begins...now!”
The first two men are stepping forward and the girls quickly hurry onto their knees sucking on the new cocks. Their heads bobble frantically trying to make them cum. Soon, their rapid stroking rewards them with their first huge load of jizz, as well as a weight on each of their nipples. They try to ignore the inevitable growing pain in their breasts and focus on finishing off the next man. At first, sister Mary is in the lead, until sister Ember catches up by choking herself on her dicks. They try their best to outdo each other until they both manage to jam the heads of the cocks into their throats with teary eyes.
When they reach 10 loads, the many weights are exchanged for a single 500-gram weight on each nipple. They can’t ignore the pain anymore, but they won’t give up.
After 20 loads, they noticeably slow down. Each time they gulp down another mouth full, they have to take a breather for a few seconds. But eventually one of them reaches for the next cock, forcing the other one to continue as well.
After 30 loads, their exhausted breathing is constantly interrupted by groans of agony. Each one has a bulging stomach expanded by a sea of sperm. They can barely move their upper body, as moving the weights shots jolts of pain through their breasts.
After a short estimation, the master congratulates them on already ingesting more than 1.5 liters (0.4 gallons) of cum. They have no idea what that means. To them, it only amounts to misery.
After the 40th load, a single 2 kilo (4.4 pounds) weight is attached to each one of their nipples. Their pleading and wailing for mercy is only met with laughter and ridicule. While they had hurried initially and tried to jerk off every man as fast as possible, the girls now kneeled there, moving as little as possible. The men do show some mercy and jerk themselves off into their mouths. The shallow breathing of the two sisters is often interrupted by coughing and belching. They can feel a buildup of saliva in their mouth. Their bodies gradually ready themselves to eject.
After load 42, sister Mary has a hick-up, which causes the weights to painfully jump. She tries to alleviate that by bending forward, but unintentionally compresses her stomach. She is holding her hand in front of her mouth. Oh no, what did she do? Is that it? She is heaving, she can feel it, there it comes.
She holds onto the bucket and hurls many streams of white vomit under a loud growling of the audience. After her stomach finally emptied itself, she collapses to the ground with the weights on her tits hitting the floor.
Sister Ember’s relief about her victory is short lived, when the stench of vomit hits her nose. Moments later, she also fills the bucket and collapses next to sister Mary.
The masters remove the weights and let them rest for a short while, while the men fetch more tools. With burning noses and throats, the girls sit on the bed, finally able to catch their breath. After a while, the speaker of the masters addresses them again.
“Blondie!”
Sister Mary looks up, knowing that she is in trouble now. The master holds a large funnel in his hand.
“It appears that you did not appreciate the gift we have provided to you. Therefore, we will put it back into you, but this time into your other end. Remove the toy in your ass.”
No, they can’t mean that can they? While everyone stares at her with a grin, she slowly removes the toy from her ass.
“The narrow end of this funnel goes into your ass, which allows us to empty the bucket into you. Then, we plug your ass, until you sucked everyone in this room off. And only then you may relieve yourself in the toilet. Do you understand?”
Sister Mary can’t believe what she is hearing. In shock she looks at the bucket filled with cum they had thrown up.
“But, but master, sister Ember also vomited into the bucket. This is not fair.”
The master is a bit shocked by the objection, but then confers with the others. After some nodding, the murmur stops and he turns to sister Ember.
“Brown-haired slave, that is true, you did throw it all up as well.”
“But master, sister Mary vomited first!”
He nods and waves her off.
“You did better than her, I agree, but not by a lot. Therefore, you will be punished as well, but not as severely. However, you will help reduce the punishment of the blond slave, as well. After all, your vomit goes into her ass as well. That much stomach acid can damage her unless we clean it later.”
“We can wash her out with some urine. But you will gather it for her, with your ass. First, we funnel the bucket into the blonde one and then funnel our piss into you. And before she sucks us off, you ride us.”
A cheer goes through the room, while sister Ember gives sister Mary an evil stare. How dare she get her into this mess? But sister Mary doesn’t even dare meet her gaze.
Sister Mary is made to stand on her head with two men holding her by each leg. The funnel is inserted into her ass and the contents of the bucket are slowly poured inside. The cold liquid enters her and slowly travels through her guts. The long funnel creates a strong pressure, causing the vomit to travel relentlessly into her. When the first parts of her intestines are fully stretched, she starts to panic. But her flailing is easily suppressed by the men holding her. When the bucket is empty, they close her ass with a wide plug and shove her into leather pants that make it impossible for the plug to be pushed out.
When she is let down to kneel, all the contents in her bowels are shifting around inside of her. It feels like she is about to burst. After a few seconds, she holds her stomach. Pain is emanating from inside. What is happening?
“Master, what is this? It burns, my insides burn. They are on fire!”
Again, her agony is met with laughter.
“That is your stomach acid my dear. It is attacking your intestines, especially any bruised or scratched spots. Did you do anything to your ass before? Hahaha”
She slowly realizes their plan. She had been fucked ferociously in all of her holes, especially her ass. Every sore spot is now burning. She grunts, holds her stomach, and kneels down in pain. Her body wants to eject her bowls and pushes, but the pants firmly keep the plug in her ass. There is no way out. She has to play their game. She needs to suck them off.
She shuffles towards the next trans sister and sucks on her cock. This time, she has no weights that prevent her from moving, but she would rather have those than the fire inside her ass.
In the meantime, sister Ember is already lying on her stomach, with the funnel in her ass. People stand around her pissing into the funnel, filling her up gradually.
Sister Mary just downed her first load and approaches the next trans sister. However, the master steps in her way and stops her.
“Not yet. Don’t you remember? Everyone gets to fuck the brunette one first and then you suck them off.”
“But master, no one is fucking her right now.”
“You have to wait until we are done gathering piss for you. How ungrateful are you?”
“I ... am so sorry, master. I ... I was too stupid to realize, master.”
She steps back and lowers her head. Once he turns back to sister Ember, she resumes fidgeting around trying to deal with her pain. After what seems forever, sister Ember is filled up and plugged up, bursting with piss in her guts. They pull her up from the floor and guide her to the bed, where the first trans sister is already waiting. Sister Ember mounts her huge cock and rides her to the best of her abilities. After a short while, she is allowed to stop and lets the next one lie on the bed. In the meantime, sister Mary gets to work the cock that just exited sister Ember's pussy, whereupon she is soon rewarded with her next load of cum.
The girls work in tandem, for a while, but after 9 loads, sister Mary is falling behind. Her stomach is cramping after throwing up and now having to endure even more cum, while the burning in her ass keeps getting worse.
By the time sister Ember is done with everyone in the room, sister Mary is still struggling to jerk off her 18th cock. Struggling with her piss filled ass, sister Ember scolds her for slowing down.
“Come on sister Mary, stop wasting everyone's time.”
“I... uuuuuugh ... I ... uuuuuuugh..."
Sister Ember rolls her eyes and walks up to the man that is next in line and starts jerking him for her. When he comes, sister Mary is shortly pulled out of her fetal position to catch everything with her mouth. They continue finishing off every cock of the brothers and trans sisters. But then sister Ember turns to the last six people who didn’t come yet: the masters.
She is holding her buttplug. Her insides don’t burn, but her sphincter is giving in. Unlike sister Mary, she did not get leather pants that hold the plug in, so she can get fucked in the pussy, but she can’t hold it much longer. Jerking off each of the masters would take too long. She will need a plan; she will need to gamble.
“Master, may I make a suggestion?”
The main master raises his eyebrows in interest.
“It seems that sister Mary is hopelessly incapable, master.”
“Indeed, quite the disappointment.”
“But she has yet to receive your cum, master. But she can do that with her ass as well, once she has voided her bowels.”
The master smirks.
“That is a good point, slave. But will that not be painful for her? It must be agonizing, don’t you think?”
“Master, she has to earn it either way, be it through effort or sacrifice. Please, master, help her.”
Now all the masters are grinning and nodding at the speaker of the masters.
“It seems you convinced us to help her then. Men, carry her to the bathroom.”
Sister Mary is dragged by her arms to the bathroom. A few seconds later, everyone can hear loud splashing of water followed by flushing. She is dragged back into the room and placed face down on the floor. After the funnel is placed inside sister Mary’s asshole, sister Ember is finally able to remove the plug from her ass and releases liters of piss into the funnel. Her moaning of relief is soon drowned out by the groaning of sister Mary, whose guts are not prepared to accommodate the new liquid. Once she is full, sister Ember inserts her plug into sister Mary’s ass and finally gets to sit down and rest.
But it is not over for sister Mary. The burning sensation has subsided a bit, but has not gone away either. They make her jump and run around, to make sure that piss washes away any remaining acid in her ass. After she finally is allowed to relieve herself in the toilet, she is told that she still has to get fucked in the ass by each master. She tries to plead and bargain, but no one shows her any mercy. When she finally lies on the bed and the first master is about to insert his cock in her aching and sore ass, he tells her that it was sister Embers’s idea. She gives her an evil eye, but sister Ember just smiles and shrugs. Before sister Mary can voice her fury, a painful dick in her ass causes her to cry out in pain.
Six agonizing butt fucks later, the masters leave and their army of slaves leave sister Ember’s chamber. Sister Mary had passed out from the pain and was carried back to her room, where she wakes up alone an hour later. After dinner, she skips stretching her ass, but still manages to sleep plugged. The next day, she does not have to do any anal sex in order to allow her intestines to heal a bit. Her grace period does not last long, as a day later, everything is allowed again. But it takes two more days for the pain to go away.
However, all the pain and suffering are just a short-lived damper for her insatiable lust. She met two of the five masters that destroyed her ass just a few days later and she could not wait to fuck and please them.
But her resentment towards sister Ember stuck with her. She thought she had an ally, a friend. But it seems, sister Ember was right all along and every sister in here is competition. Sister Mary has to keep training, keep getting better and push herself. She stretches as much as she can and tries to make every man cum as often as possible. She needs to be able to swallow anything if she wants to succeed.
After three weeks of lactating (day 47 at the institute), her milk production has reached 5 L (170 ounces) per day. She sits on her bed, waiting for her next master, trying to appear patient, not showing how she struggles with her tits filled as if they are about to burst. When the door opens, she gladly shouts
“Good morning, keeper of my tits!”
“Wow, look at you. I haven’t seen you for a few weeks and your tits are massive!”
She holds them up to him.
“They are all yours, keeper of my tits.”
He gently brushes her leaking nipples and a few seconds later, milk is shooting in arches across the room with a shiver of excitement causing sister Mary’s body to shake. She stands up to him, hoping he would touch her more, but he guides her back to the bed. He lifts her breasts a little, trying to assess their weight.
“They are so full, my little slave.”
“Please, milk me, keeper of my tits.”
He puts her right nipple in his mouth and starts sucking. She immediately melts away in pleasure when her arousal is answered with stimulation and in relief when her tits are being drained. However, her enjoyment is short-lived as he stops soon after.
“Impressive, they are bursting with milk. You have my permission to drain them, but only without touching them. Here is a small metal bucket. Your task is to fill it with your milk. That should be about 300 ml (10 ounces).”
She tries to catch a few of the streams coming out of her nipples, but the flow trickles off, since her master stopped touching her. She looks a bit puzzled at the master, who just smirks at her. After a short pause, she smirks back at him, falls on her knees and sucks him hard. Once he is stiff enough, she jumps on him and passionately rides his cock and soon after, milk starts pouring again into the bucket.
Her master enjoys her initiative when she pulls out his cock and inserts it into her ass. After a while she jumps down and starts choking herself with his dick in her throat. No matter what she does, her tits keep ejecting milk. His pleasure is her pleasure and she keeps enjoying herself.
She is riding him again, when she notices that her bucket has already filled and shows him the bucket, without slowing down her movements.
“Good girl. Now, drink it!”
She smiles, shrugs and downs the entire bucket.
“Keeper of my tits, let’s fill another one, please.”
Her master is stunned by her enthusiasm, but nods, leans back, and enjoys the show. Happy about the approval, she speeds up her movement and soon after comes hard. However, she does not give herself too much time to relax and jumps off him in order to open the drawer.
“I can’t touch my tits, but can you, keeper of my tits? Please?
She hands him a box of needles, sits next to him and presents her tits to him. Her master raises his eyebrows at her, gives it a quick thought and opens the box.
“Well, I only have myself to blame if you find a loophole. Come here sugartits.”
He inserts two needles into each nipple, causing her to moan every time. It takes him some time, as he has to wait for the milk to stop streaming out of her nipples.
“Keeper of my tits, may I attach the bucket to the needles? Then I don’t have to hold it anymore. Maybe you even have a second bucket for me?”
Sure enough, he pulls out a second bucket and they attach handles of each bucket onto her tits. She gleefully shakes her tits with the dangling containers, but has to stop herself, when she buckles under the pain of the weight. Once she has composed herself, she walks around and gathers the largest toys she can handle and puts them next to him on the bed. Then, she walks up to his side and carefully puts herself over her master's knees so that her legs are dangling off to one side and her head and her massive udders off the other side.
“Please, keeper of my tits. Can you make me cum or hurt me... or both? I’m sure we can fill the buckets.”
He runs his hands up her legs and probes her soaking wet pussy, followed by her puckered asshole. After a few seconds he can already hear milk flowing into both buckets. Next, he takes her dildo and ruffly jams it into her pussy. Despite being lubed up so much by her own juices, it takes him a bit of time to fully get it in. Sister Mary groans in pain, but the trickling milk tells him otherwise.
Once her pussy is full, he proceeds to push the plug into her ass. However, once it is about half way in, it jams more and more against the dildo in her pussy. She does not stop him, but her legs are rising in order to deal with the thin wall between her ass and pussy being painfully squeezed so tightly. Seeing how bravely she keeps fighting he does not stop and keeps pressing through her screams until the plug is forced into her ass. Her screaming subsides and after some heavy breathing, her master can hear a bit more milk pouring into the buckets. However, after some time it stops again. When nothing more happens, sister Mary starts to sob a bit.
“What is the matter, honey?”
“I can’t get out anymore. I’m trying, but the milk is not coming anymore, keeper of my tits.”
“Does the weight of the buckets hurt?”
“Yes, it does, keeper of my tits. But I don’t know how to get more milk out of them.”
“I guess we completely drain them, my slave.”
Sister Mary is silent for a moment, but comes up with a suggestion.
“Wait, keeper of my tits, you can inflate my tits. That might push out some more.”
He helps her get up on her feet. Her nipples are hurting a lot, but she does not care. She wants to see if she can achieve his task. The master comes back with the gun but also brings her the vibrating toy.
“I like your resolve, honey. Here, use this while I expand your tits. Maybe it helps.”
She sits on the bed, grinding the toy against her crotch while her master is heating up her breasts with the gun. When the implants expand, they push from the inside and more milk is suddenly squeezed out her nipples. Her master keeps expanding, maintaining the flow of milk. The weight on her nipples, the pressure inside her tits, the toy against her groin, it is too much for her. Sister Mary experiences one more massive climax, which is still dying down when her breasts are fully expanded. She tries not to spill too much out of the buckets, but they both know that they succeeded.
He takes off both buckets and hands her one of them.
“Cheers, slave!”
“Cheers, keeper of my tits!”
She downs the bucket of milk and smiles at her master, with blood running down her tits and her holes painfully stretched. She catches her breath and suddenly jumps up.
“Keeper of my tits. I am so sorry; I have failed to make you cum yet.”
She drops on her knees, trying to suck his cock, but he pushes her away.
“You know what, slave? I think you have done enough for me today.”
Confused about his words, she pauses, looking at him in shock and panic.
“Don’t worry, I mean it. I had a lot of fun today ... But I think we may part ways here.”
“I don’t understand, keeper of my tits.”
“Ah, that is ok. That is not the first time for me. It is fun to break a new girl. To inflict pain, to torture the spirit. But you have evolved too much already. I’ll have to find a new girl to torment.”
“I am so sorry, keeper of my tits.”
“Don’t worry, you can call me, eh ... master, I guess. I’ll go and check if there is a new girl to jizz into. Any tips for dealing with her? What scared you the most?
Sister Mary pauses to think for a second.
“I am the most terrified when you say nothing. I felt scared for my life.”
“I like to hear that, slave. Who knows, maybe you will hear the new girl scream later today.”
“I sometimes do hear that, ... master.”
After an awkward pause he gets up.
“Goodbye, slave. I might check in again from time to time, I don’t know yet. But I definitely will pay them to pump your tits up as much as possible, don’t worry.
“Master, why do you do this to me? What is the purpose of making me carry around these large breasts for the rest of my life?”
His smile turns into a stern look.
“I had this done to so many girls that I don’t even remember. What did they look like? What did they say to me? What efforts did they make to please me? I have already forgotten it all. To me, my orders are nothing but a fleeting thought that entertained me for a moment. You are asking me for the purpose of the struggles I cause you? You search in vain.”
She does not know what to say, and can only stand there as awkward as the toys in her holes allow it. The sound of another drop of blood falling from her nipples to the floor echoes through the room.
“Hehe, thanks, slave. You were able to please me one more time with your moment of bleakness and misery. I wonder if I’ll be this lucky with the next girl.”
After the door closes, she sobs and slowly walks to her bed. Before she can sit down and gather her thoughts, the monitor beeps and announces her next master in 5 minutes. Like on autopilot, she pulls out all the needles, disinfects her nipples, and removes the toys out of her ass and pussy. She hurries to her bed, sits down, and tries to gather her thoughts. What did the master say again? He loves torturing her tits. Her nipples are sore. She touches them and it hurts, but in a good way. She continues to pinch them and rolls them between her fingers. It feels good. Her pussy starts to tingle. It’s so empty. She would like another cock. Her horniness returns again. She can’t wait for the next master. The door opens.
