BOOM! BOOM! BOOM!

Multiple explosions erupted throughout the city as they were attacked by a hoard of monsters lead by the Monster Association’s Monster Princess Do-S. Thanks to her more human appearance she was able to blend with the humans before the attack. Though that is to say if one wasn’t looking at how she was dressed.

It wasn’t very wise of her to roam the streets wearing a revealing BDSM outfit made up of tight straps and held by metal rings that showed off her curves. It was lucky for her that most people were used to seeing people in weird costumes thanks to all of the heroes roaming around these days.

When the first wave of monsters came pouring in Do-S took charge, making sure that none would stand in her path. It was at this time that four foolish heroes were sent out to stop her.

Darkness Blade, Saturn Man, and Pandaman were more than easy to defeat. All it took was one single strike from her whip to turn the three of them into her obedient little love slaves.

“What have you done to them!?” Dynamite Man, the last of the four-heroes yelled at her. His terrified expression from seeing his allies turned into her slaves, turned her on.

“These three disgusting pigs are nothing more than my mindless slaves,” she said, whipping Pandaman in the back with her whip. The eyes just like the rest were hearts shaped.

“Anyone who gets hit by my whip is turned into my obedient little love slave. No matter how powerful that power is worthless before mine,” she said, slowly moving het hand across her breasts, which to Dynamite Man’s dismay actually turned him on a bit.

“Unfortunately for you someone with your looks isn’t even fit to touch my feet. Boy’s remove that horrible insect from my sight this instant!” she yelled, whipping them several more times before they charged straight at Dynamite Man.

However, before her love slaves could get close to Dynamite Man each was of them was subdued by the Blizzard Group! Just mire pesky heroes that dared to get in her way.

“How dare you interfere!” she yelled at them cracking her whip against the ground in frustration. “No matter, you will all turn out just like the rest!” Do-S tried hitting them all with her whip but was shocked when she saw it stop in midair.

“Who dares!?” Do-S yelled looking around. “How dare you get in my way!” she yelled at the unknown person that got in her way.”

“How dare you treat others in such a disgusting manner?” Fubuki asked with a cold expression across her face, as she floated down from above, landing right in front of Do-S.

“Well look what we have here, the loli’s big titted little sister,” Do-S said, looking directly at Fubuki’s tits, wondering just how big they really were.

“My eyes are up here,” Fubuki said coldly to her.

“Oh, I know that, but I doubt that such a big titted bimbo like yourself even has a brain,” she said mocking Fubuki in front of her subordinates. As the number 1 B ranked hero, she would not let this woman treat her as some common fool!

Before Fubuki could react Do-S was already swinging her whip right at her. In the last second, she was able to block it was her telekinesis, but it was clear to her now that she underestimated this thinly dressed monster.

“Come on where’s all that confidence you had a second ago!? Do-S yelled, whipping her whip faster and faster at Fubuki who was barely keeping up with her. If only she was as strong as her sister than she would have just ripped the whip out from this bitches’ hands, but with her level it was impossible.

“Oh, would you look at that, little miss bimbo is all alone now,” Do-S pointing behind Fubuki.

Turning around to see what she was talking about Fubuki was shocked to see that Dynamite Man and all of her subordinates’ eyes were shaped like hearts and each one of them had perverted expressions across their faces.

“How!?” Fubuki yelled at Do-S, confused to how this happened.

“This is why you’re such a bimbo!” Do-S said mocking her. “What did all of your brain cells end up going to your tits and ass? I was never attacking you to begin with! Every time you blocked my whip you accidently sent it right into the direction of one of your own subordinates.”

“Thanks to you each one of them became my love slaves. Now the big titted bimbo is all alone, but don’t worry, you’ll be just like them soon enough,” Do-S said, licking her lips from underneath her mask.

“Heart Hard Hit!” Do-S said cranking her whip sending multiple slashes towards Fubuki who was barely able to stop them all. She could feel herself getting more tired the longer that this battle stretched out. She needed to figure a way to stop this monster.

“This is no time for you to try and develop a brain bitch!” Do-S yelled mockingly at her. “Let’s make things a bit more fun. Oh boys, obey your mistress and hold down this fat cow for me!”

“What are you doing! Stop this!” Fubuki desperately tried to get her subordinates to go back to their senses, but it was no use. They were nothing more than mindless love slaves obeying their mistress’s command.

“Heart Hard Hit!” Do-S yelled once again, launching multiple slashes at Fubuki with one crack of her whip. Fubuki tried her best to block all of them like she had before, but since she was too busy trying to keep her subordinates away as well, Do-S’ whip managed to pierce though her telekinesis, hitting her right in the gut.

Fubuki almost dropped to her, knees, but managed to stay strong. Though this gave Do-S the chance to hit her multiple times in a row, effectively putting her under her control. Fubuki’s body felt limp to her, almost as if her entire body was asleep, but her mind was awake. She tried to move but it was no use.

Seeing that Fubuki’s body was now under her control Do-S slowly made her way over to her, a sadistic smile spread across her face.

“Finally, your fat ass and tits are now under my control,” Do-S said, slowly stroking Fubuki’s breasts before grabbing her fat ass. “Oh, how I would love to have my way with you, but that will have to wait, you were only the appetizer, and I’m here for the main course.”

“…”

“Oh, that’s right you can’t even respond back to me anymore. Well since I know that bimbo brain of yours can’t figure this out without help, I guess I’ll just tell you,” Do-S said whispering in Fubuki’s ear, causing her to blush. No other woman besides her sister had ever gotten this close to her before, so didn’t know how to react.

“The reason I came to this city of all places was none other than that loli big sister of yours. As Japan’s number 2 hero she possess a threat to the Monster Association and I have been ordered to remove her from field of play.”

“Meeting you her younger sister mere minutes after our attack began was nothing more than a stroke of good fortune. Using her own sister’s screams to lure her out will be most assuming. I can’t wait to see her face when she sees your new bloody and beaten form.”

No! Fubuki wouldn’t allow this monster to use her to harm her sister! She had to break free! Using her willpower Fubuki broke free of Do-S’ mind control! She would stop Do-S and protect her sister!

“Hell Storm!” Fubuki attacked Do-S with all she had, smashing her into the ground! Do-S couldn’t fight back against Fubuki’s raw untamed power. She underestimated Fubuki thinking that she was nothing more than a dumb bimbo. But when it came to protecting her sister, she was unmatched.

“You did well,” Tatsumaki, said as she flew over to her sister. “I saw everything. Not only did you defeat this monster, but you freed everyone from her control.” Yes, this was what she always wanted, her sister to acknowledge her. Finally, her sister no longer saw her as a waste of space. “You’re such a good girl,” she said patting Fubuki’s head.

“You’re such a naughty girl,” Do-S said, grabbing Fubuki’s tits. “You just stood there and listened while I threatened to kill your own sister. My oh my what a naughty bitch you are.”

Fubuki just stood there, her eyes shaped like giant pink hearts. What had just happened was all in her mind. None of it was real. Someone as weak as her stood no chance against Do-S. All she was good for was becoming another one of Do’s love slaves.

Now all that was left was figuring a way out how to use this bimbo to lure the loli bitch out.

BOOM!!!

All of a sudden, another explosion erupted in the city, but this time it wasn’t caused by a monster, it was caused by Tatsumaki. Do-S immediately realized that she was no match for Tatsumaki and decided that it would be best for her to withdraw with what few trophies that she had gained so far.

BOOOM!!!

Another explosion caused by Tatsumaki erupted and just as Do-S was about to make her retreat, a monster under her command landed directly in front of her, almost crushing her.

“Princess pl…ease he…lp me, she’ com…ing” the monster reached out its hand towards Do-S, but before he could get closer, he was crushed under the weight of Tatsumaki’s telekinesis.its

“Another pest dealt with,” Tatsumaki said, as she flew down to the ground in front of Do-S who stood there shocked by her power.

“Fubuki what the hell are you doing here, go home,” Tatsumaki said, practically ignoring Do-S. “Fubuki answer me!” she yelled, getting mad that her sister didn’t give her an immediate answer.

“You! What did you do to my sister?” Tatsumaki asked, ignoring the fact that there were other heroes under Do-S’ control as well.

“I don’t know what you mean,” Do-S said slowly making her way back to Fubuki. “We were having a chat; a little girl talk if you would.”

“Don’t mess around your obviously a monster that has taken control my sister's mind,” Tatsumaki said in a menacing tone, which almost made Do-S pass out from fear.

“Well, if there is no use trying to trick you, then there is no need to wait for me to do this, Love slaves attack Tatsumaki!” Each one of Do-S’ love slaves charged at Tatsumaki, except for Fubuki who she gave the order to fall unconscious. While Tatsumaki had to immobilize the rest of the love slaves Do-S used this chance to flee with Fubuki, determining that she has a far greater use than just being a mere love slave.

When Do-S finally made it back to ten Monster Associations headquarters she made her way over to make her report.

“So, you mean to tell me that you failed to kill the number 2 hero Tatsumaki,” Orochi the Monster King said, in a disappointed tone.

“Please forgive me!” Do-S cried out, begging for forgiveness. “I determined that Tatsumaki was too powerful for me and made a strategic retreat.”

“What is stopping me from killing you here and now?” Orochi said, getting ready to get rid of Do-S.

“During the battle, I managed to enslave and capture Fubuki,” Do-S said pointing over to the unconscious Fubuki propped up against the door.

“I have to say I wasn’t expecting you to be able to capture Tatsumaki’s younger sister so easily. As your reward, I will not only spare your life but allow you the privilege of raising her into a proper monster fit for my army.”

“Yes, Orochi-sama! I will do my very best to meet your expectations!” Do-S cried with joy.

“You’d better not fail me,” Orochi said as he dismissed her. “If you do, I am sure that you know what will happen?”

I promise that I will not fail. you Orochi-sama. The next time you see this big titted bimbo she’ll be a monster that is fit for your army. You won’t even recognize her as Fubuki once I’m done with her!”

Do-S happily made her way out of the throne room with Fubuki hung over her shoulders. When she finally made her way back to her room she collapsed from exhaustion. While Orochi-sama may have been her master and loved him more than anyone else in the world, she was still deathly terrified of him.

One failure was all it took to destroy the confidence that she had with him. If she hadn’t told him about Fubuki when she did, she would have died right there. She had to make sure that she turned Fubuki into the perfect monster, that would never disappoint Orochi-sama.

To train her to be the perfect monster she would have to make sure that she was in complete control. She had to make sure that there was no way for Fubuki to resist her.

Do-S looked down at Fubuki and sighed. Why would such a big titted bimbo like her try to hide those assists of her? Wait that was it, the perfect method of breaking her!

Do-S wasted no time after that tearing off her dress and underwear. Ugh beige, did this bitch really think she could lure a man in with beige underwear? Well, no matter since this would be the last time, she’d be wearing ugly clothes like this.

Do-S looked down at Fubuki’s massive naked tits and smacked them in frustration. What did she do to make them so big? Is she the reason why Tatsumaki has mosquito bit tits?

Do-S went into her dresser and brought out one of her spare outfits and wasted no time putting it on Fubuki. When she was done Fubuki was dressed like her from head to toe with the exception of her mask. Do-S didn’t want to miss the chance to see Fubuki’s horrified expressions as she was being trained.

There were also two non-visible traits that this spare outfit of hers had. For one once it was put in it could not be taken off by anyone besides Do-S herself. And two while stuck in this outfit Fubuki wouldn’t be able to use her telekinesis to escape. Such a pesky power had to be dealt with early on.

Now all that was left was to wake her up. Do-S pulled out a smelling salt and then snapped it open under Fubuki’s nose. Seconds later Fubuki sat straight up looking both confused and a bit wired.

“What’s going on? Where am I?” Fubuki asked herself not noticing that Do-S was standing to the right of her.

“Did the big titted bimbo have a good nap?” Do-S said, wasting no time to scare Fubuki.

“What the heck! It’s you! Why are you here!?” Fubuki yelled trying to use her powers against the monster woman but for some reason, they wouldn’t work.

“What’s going on? Why won’t they work?” she asked herself while still trying to use her powers but to no avail.

“I knew you were dumb, but I didn’t know you were this dumb,” Do-S said to Fubuki. While it was fun watching her freak out over the loss of her powers, what was about to happen next would be much more enjoyable. “Maybe the bimbo should look down first before asking any more questions,” Do-S said pointing down to Fubuki’s current attire with a sadistic grin across her face.

“What ar- Ekkkkkkkkk!!!” Upon seeing her currently, outfit was the exact same BDSM outfit that Do-S was wearing Fubuki screamed out in embarrassment. Her face turned flushed and all she could think about was what her sister and teammates would think about her if they saw her dressed like this.

“Is the little bimbo embarrassed?” Do-S said, lifting up Fubuki’s head by her chin to see her flushed and now crying face.

“Why are you doing this you bitch!?”  Fubuki yelled, slapping Do-S’ hand away with one hand while desperately trying to cover her breasts with the other. She’s never been this exposed in front of another person before. This was worse than the time that Tatsumaki show her classmates her bra back when she was in high school.

Smack!

Do-S slapped Fubuki in the face so hard that she crashed straight into the ground.

“You big titted bimbo bitch!” Do-S yelled at Fubuki as she pinned her head down to the ground with her heel. “It would seem that you have yet to understand your position here. Let me explain this in a manner that even a tits for brains bimbo like yourself can understand.”

“That sexy and revealing new outfit of yours is now your permanent outfit. Think of it as your new uniform courtesy of the Monster Association, which you have just been welcomed as our newest member.”

“Though that outfit of yours doesn’t just make you look like the slut you actually are deep down inside. This outfit is made of the same materials that you hero use on villains when you lock them up. This means if you haven’t realized it by now that you can no longer use that pesky telekinesis, you’re so proud of to try and escape.”

“Oh, and I wouldn’t bother trying to take it off. The outfit is coded to my DNA. Trying to take it off would be a fruitless effort,” she said anticipating Fubuki’s thoughts.

“Now that we have that all cleared up, let’s get down to business,” Do-S said taking her heel off of Fubuki and bending down towards her before grabbing her by her hair, making her eye level.

“I know I just said this, but I will say it again so that it can sink into that bimbo brain of yours. As of this right now you are both the newest as well lowest member of the Monster Association. Let me be the first to welcome you and congratulate you from your career change from Hero to Monster!” Do-S said, laughing in her face.

“No, I refuse!” Fubuki yelled back at Do-S causing her to throw Fubuki to the ground. “I’ll never be a Monster! I’m a Hero!” Fubuki was not going to fall into despair just because she was kidnaped and dressed in such a vulgar manner. She would fight back because she knew that her sister would eventually come for her.

“You annoying little bitch!” Do-S yelled at heard. “Are you trying to blow my eardrum out?”

“The Hero Association won’t rest until they find me! You know exactly who my sister is, and you have already run away from her once. Isn’t that why I’m here, because you fucked up and needed a shield to escape?”

“I have to say that I like you better when you were nothing more than one of my love slaves,” she said pulling out her whip. “You didn’t talk and just stood there like a good bimbo. It’s unfortunate for you that I require something much more than a love slave.”

“I’ll never obey you!” Fubuki yelled, rising to her feet in defiance. Even with her powers sealed, she was the number 1 B-rank hero. She would never lose to the slut before her in a fair fight.

“Aww that’s actually cute despite how much of a slut you look like right now,” Do-S said, cracking her whip on the ground.

“Look who’s talking bitch!” Fubuki yelled at her. “I bet without that whip of yours I would beat your hands down in a one-on-one!”

“OMG! This bitch can’t get any dumber can she!?” Do-S started to laugh at Fubuki. For someone that was supposed to be the number 1 B-ranked hero, this bitch knew nothing about a monster’s physical abilities. Even for someone like her, her strength was equivalent to a semi-truck.

“Fine you asked for it,” Do-S said, throwing her whip down to the ground. “If you someone how to manage to win I’ll let you go. But if I win… well it’s already a given what will happen to you after this so have fun with this one last sliver of hope.”

“You underestimate me,” Fubuki said preparing to fight.

“No, you overestimate yourself and underestimate me!” Do-S said getting behind Fubuki before she could even react! Then without warning, she dragged the struggling Fubuki to her bed and put her over her knee.

“What are you doing!?” Fubuki yelled in protest, but it was no use. “This was supposed to be a fair fight! Let me go!” Fubuki tried to worm her way out of Do-S’ grip, but to only her surprise Do-S was far stronger than she realized.

“Face it tit’s for brains, you lost,” Do-S said to her. “We just had what you would call a fair fight, now get ready, because mommy needs to vent a bit, thanks to a certain big titted bitch today been nothing but one big ordeal.”

“What are you-”

SLAP! SLAP! SLAP! SLAP!

Do-S began to spank Fubuki over and over again. Which each hit Fubuki’s ass became redder and redder, and this continue for a total of fifteen minutes!

At first, Fubuki was defiant against her, demanding to be let go. By the time she was halfway through Fubuki began to scream in pain for Do-S to stop. For the final five minutes, Fubuki was a sobbing mess.

“Please stop! I’m sorry! I’m sorry! I’m a big titty bimbo! Please just stop.” Only after a mere fifteen minutes had passed and Fubuki was already to submit to Do-S. However, this was the first step.

Fubuki was only begging her forgiveness at this moment. If Do-S gave her a few minutes to recover that defiant attitude of hers would return.

“Sorry, but there is still so much more that I have planned for you,” Do-S said to her in a sadistic tone. “Why should we stop the fun when we’ve only just begun. Now be a good bitch and tie yourself up in that,” Do-S said pointing to BDSM cuffs and shackles on the other side of the room.”

“No… I won’t do it,” Fubuki said, her disobedient nature returning just a mere few seconds after Do-S stopped spanking her. It would seem that she would have to spend some extra time breaking this one.

SNAP!

Do-S snapped her fingers together and Fubuki’s eyes turned into hearts and seconds later she willfully walked over to the BDSM restraints, locking both her ankles and then wrists up. Do-S then walked over to her and tied her up a bit more to make sure that she wouldn’t be able to move.

SNAP!

Do-S snapped her fingers once more and Fubuki regained her senses and was shocked by what she had just done.

“You bitch! What did you do to me!?” Fubuki yelled trying to break free of the restraints that she put herself in.

“You really don’t learn,” Do-S said, bringing out her crop whip. She always made sure to save this for special occasions and what time was better than right now to do so. “Every time you speak it’s almost as if you’re giving me another reason to justify calling you a bimbo.

“Let me go!” Fubuki yelled full of defiance. This was why Do-Ss knew that she was going too easy on her.”

SMACK! SMACK! SMACK!

Do-S wasted no time whipping Fubuki on her ass. Fubuki would learn who was in charge here even in Do-S had to beat it in her.

“Stop! Let me go!” Fubuki yelled in protest, and every time she did she Do-S whipped her harder. There was no longer a reason to go easy on her. Fubuki’s will had to be broken.

Unlike the spanking which only lasted for an hour, Fubuki’s whipping lasted more than an hour. However unlike with the spanking this time she decided to stay strong. The how time she held back her screams of pain and just launched insult after insult at Do-S who was happy to see her defiance. The stronger-willed ones were always more fun to break.

“I think we can stop here,” Do-S said as she heard a knock on her door. When she opened the door what she ordered for Fubuki while she was “training” her finally arrived.

“Oh my, I am sure that my little bimbo is going to love this,” Do-S said to herself. She couldn’t wait to see Fubuki’s face when she showed her what she ordered for her.

“What’s going on?” Fubuki asked, trying to figure out what Do-S had planned, but if she wasn’t the impatient bimbo that she was she would know that she should just wait for her new mistress to present it to her.

“No more training for today,” Do-S said, taking off Fubuki’s restraints and then dragging Fubuki’s weakened self over to the side of her bed where a chain and collar with the letter m on it were attached. Do-S wasted no time placing the collar around Fubuki’s neck and then making her sit down on her fat ass.

“What’s this for?” Fubuki asked, tugging at the chain to see how strong it was. All at the same time, Do-S opened up the package bringing out what looked like a doggie bed.

“Lookie here my little bimbo!” Do-S said as she spun around to show the doggie bed to Fubuki. “Can you guess what this is?”

“It’s a dog bed,” Fubuki said to her confused. “Do you have a dog or something?”

“Matter a fact I do!” Do-S said to her with a sadistic smile across her face. In fact, I just got her today and I’, looking right at her. While she may be a pretty thing on the outside I’m afraid that she lacks on brain cells, but smart dogs are overrated, wouldn’t you agree?”

“Are you calling me a dog!” Fubuki yelled back at her in anger. “I am Japan’s number 1 B-rank hero! I-”

“And I don’t care,” Fubuki said, tossing the doggie bed down right next to Fubuki. “From now on that fancy title means nothing to me or you. Right now you are nothing more than a disobedient dog that needs to be trained. That is also why I order this as well, she said pulling out a giant dog bowl with Fubuki’s name written on it.

Do-S placed the bowl on the ground in front of Do-S before turning around to get one more thing out of the box. When she turned around she was holding what looked like a can of food. Unbeknownst to her, the food inside that can could be classified as anything but normal. The food that was inside it was the Monster Associations' new monster transforming food.

The Monster Associations' original monster transforming food was too unpredictable and there wasn’t that high of a success rate. Luckily for her Do-S was able to request the newer version to be used and tested on Fubuki. In addition to that, she made sure that it was laced with additional ingredients that would make Fubuki’s transformation from a top hero to the lowest monster girl.

Do-S opened the can and took a whiff of it before dumping it out in Fubuki’s bowl. “Here you go my annoying little bimbo and eat up so you can become a monster just like me!” Do-S said to her.

“What are you talking about?” Fubuki said pushing the dog bowl away from her. “I’m not eating this and you can’t make me!”

“Ever the defiant bimbo you are,” Do-S said to her in a kind tone. “You know I admire your defiance I really do, but sometimes it’s best for a dog to do what their master tells them to do!” Do-S yelled at her changing her tone, as she shoved Fubuki’s head face-first into the bowl!

“Eat it you dumb bitch!” Do-S sadistically yelled at her, making sure that her face stayed firmly planted inside the bowl. “If you don’t eat you’ll suffocate soon. I’m certain that you’re not dumb enough to want to die now are you?”

Fubuki tried to struggle to get free but it was no use Do-S was just too strong for her. She was right. If Fubuki wanted to live she had to eat this disgusting food no matter what it was or what it would do to her. She just needed to be patient and wait for her sister to come to rescue her.

Fubuki began to chow down on the food, despite it being less than edible. She had to force herself back from puking since she knew that Do-S would try to make her eat it as well.

The more that she ate the warmer her body became. Bit by bit her tuts, ass, thighs, and hips started to grow. It was just by bit for now. But Do-S noticed this and was pleased. The more that Fubuki ate this mixture of the monster transformation food and the bimbo body drug that she had spiked in it, the faster that Fubuki would become the bimbo that she truly was.

When she was done eating all of her measurements had gone up by 1-3cm. It wasn’t that big of a change, but it would be worth it in the end. Do-S then yanked Fubuki’s head up to make sure that she had eaten everything.

“I’m impressed,” Do-S said patting her head. “You ate everything and even licked up the sides. That's a good girl. We’ll make an obedient bimbo out of you just yet. That being said it’s time for bed. I’ve been up all day and I need some sleep. You go to sleep as well.”

“Sleep? Where the hell are you telling me to sleep, the floor?” Fubuki asked for some reason not as mad at her anymore. Fubuki didn’t realize it because the drugs and the first step of her “training” was already taking effect. Do-S wasn’t known as the Monster Princess for nothing. There was no creature alive that wouldn’t eventually bend to her will.

“I may be a monster but I’m not cruel, your bed is over there,” she said pointing to the doggie bed right next to Fubuki.

“I’m not a dog! I refuse to sleep on that!” Fubuki yelled.

“It’s either that or the floor,” Do-S said to her. “That chain is stronger than any amount of force that you can muster. So it’s no use trying to escape.”

“What about the toilet!?” Fubuki asked as she started to feel, the urge to go.

“Oh my, that’s my bad,” Do-S said, making her way back to the package and pulling out a doggie potty mat. She then laid it down right next to Fubuki’s new bed before walking back to her own.

“There you go sweety,” Do-S said to her in a sadistic tone. “Now make sure to be a good girl and do your business there from now on.”

“You can’t expect me to use that like some common mutt!” Fubuki yelled at her but still couldn’t find the strength to stand up. “I won’t do it! I refuse.

“Well if the bimbo wants to wet herself like a baby then be my guest. That chain is only 6 feet long. Just long enough for you to sleep in your bed and use your potty, nothing else. Oh, and if you think about doing your business in my bed I won’t be as nice as I have been thus far.”

“You call this nice?” Fubuki mumbled under her breath.

“What was that?”

“Nothing,” Fubuki said reluctantly making her way over to the pads. She knew that she was giving Do-S there was no other choice.

As Fubuki got into position her heart started to beat faster not because she was scared, but because she felt excited!

Thump! Thump! Thump!

Fubuki could practically hear her heartthrob in excitement as she let it go. Why was she having these sorts of feelings? What was happening to her?

“That’s a very good girl,” Do-S said, watching Fubuki cry as she was forced to relieve herself on the doggie potty mat.

Do-S went to sleep that night happy with the progress that she made with her new pet. Fubuki on the other hand cried herself to sleep as a mix of emotions ran wild inside of her mind.

For the next serval days, the same process would be repeated over and over again, instilling into her mind that Do-S was above her and that Orochi-sama was her lord and master, her king.

Fubuki did the best she could to fight her, but as the days when by her breasts, ass, thighs, and hips continued to grow larger and her body began to grow more sensitive as well. She was now aware of what the food Do-S was feeding her, was doing to her and her body. Though just like the dumb bimbo she was she never even considered that it was affecting her mentality as well.

Fubuki no longer fought back while eating the food and started eating it of her own free will. She shoved her face into the dog bowl that Do-S gave her and ate it all with her mouth every time.

As for her “training” Fubuki’s protests soon turned into screams and then into lustful moans. With each hit, she received from Do-S’ whip a wave of pleasure spread across her body causing her to let out another lustful moan. Each moan was music to Do-S’ ears.

As for using the bathroom, Fubuki started to feel more and more excited as Do-S watched her. She could now only go if someone was watching her do it, or it wouldn’t be the same for her.

After a week of the same “training” Fubuki’s body was finally trained enough and had become sensitive enough for Do-S to enter the next stage of Fubuki’s transformation.

While it had already been a week Fubuki’s mind while now disorganized was still strong. She would need to thoroughly destroy her mind before she was ready for Orochi-sama.

While Do-S thought about what to do next. Fubuki was left alone to look at herself in the mirror that Do-S provided for her. She was disgusted by her new form. Her bust size went from being an F-cup all the way to  J-cup breasts.

Her ass was now a huge bubble butt that ate her thong! Her hips and thighs even her out and gave her a curvier hourglass figure, but it was still hard for her to look at. She looked like a slut! Most people wouldn’t even believe that she was the number 1 B-ranked hero if they saw her like this.

Her skin had started to turn pale and her right had already been turned into the same dark monster eyes that Do-S had. She could feel her teeth start to become sharper and for some reason, her mouth felt strange. It was almost as if it was too small

“That’s it! I can’t take it anymore!” Fubuki yelled in rage as she charged Do-S she was now close enough for her to attack. Though unfortunately for her Do-S saw this coming and knocked her down to the ground.

“Tsk, tsk, it would seem that the bimbo still has a bit of fight left in her. Let’s fix that shall we,” Do-S said, turning around and being down so that her ass was now inches away from Fubuki’s face. “Apologize.”

“What?” Fubuki asked confused by what Do-S was doing.

“Kiss my fat ass to apologize to me,” Do-S said to her. “Or would you rather I spank you until I say you’re forgiven.

“I want the spankings,” Fubuki said without hesitation. Spanking felt good to her more than anything right now. She would rather do that than kiss this bitches ass.

“Alright you asked for it,” Do-S said as she walked over behind Fubuki who already had her ass in the air, getting ready for her reward, wait no punishment.

Swat. Swat. Swat.

Do-S slowly and lightly started to slap Fubuki’s ass. While didn’t hurt Fubuki was getting frustrated, She want Do-S to hit her as hard as possible. There was no point in getting a spanking if it was just going to be like this!

“No, no, no!” Fubuki screamed in frustration! “Hit me harder!”

“I gave you a choice and you choose this,” Do-S said mocking her. “You choose this. Though if you would start kissing my ass as I told you to do before perhaps I could spank you harder.”

“Really!?” Fubuki said back excitedly, not realizing that her from a week ago would have been repulsed by her current actions. “I’ll do it so please hit me harder! I need it!”

“Oh my, what a little M you’re turning into,” Do-S said happy with Fubuki’s progress. “Here you go, kiss it really well,” she said shoving her fat ass right in front of Fubuki’s face.

“I’m sorry, I’m sorry,” Fubuki said with each kiss. Over and over she began to apologize, begging for forgiveness. He had to be out of her mind to even think about attacking her mistress, wait mistress? Yes, this lady gave her what she need she was Fubuki’s mistress.

Fubuki was slowly starting to lose her mind. How long she would be able to hold onto her old personality was no longer up to her. It was now entirely up to Do-S and she had one final thing planned for Fubuki before erasing her old personality completely. Though for now, it was time to give Fubuki her reward for being such a good bimbo slave. For the rest of the day, the sounds of lustful moans could be heard from Do-S’ room.

Another week had passed and Fubuki was now completely a monster just like Do-S. Her skin was completely pale just like Do-S’. Both of her eyes had become dark monster eyes as well. Her teeth became as sharp as Do-S and her mouth had widened and cracks started growing on the side of her cheeks. Finally, her tongue was as long and flexible as Do-S’ who made sure in this past week that she was properly trained in using it.

“Congratulations Fubuki,” Do-S said happily, reading the lab results in her hands. “As of today, your body is no one hundred that of a monster! Hurray! And thanks to the fact that I gave them my DNA to put into your monster transforming food, we’re now basically sisters! What do you have to say about that Fubuki, my dearest big titted bimbo?”

“….”

“Oh that’s right you can’t talk like that now can you?” Do-S said, standing up to reveal that she was using Fubuki’s face as a chair.

“I’m sorry mistress, I didn’t hear that,” Fubuki said, licking her lips. While at first she hated getting sat on, she eventually started to feel pleasure from it.

Over the course of this week, Fubuki stopped resisting Do-S. the more that she did the further that she would lose herself in the process. Though after what she felt by being sat on could say that she had officially awoken the M inside of her.

“I said that we are basically sisters now,” Do-S said to her submissive slave. I will have to think of a new name for you later, but for now, it is now time to introduce you to your new master Orochi-sama.”

‘Orochi-sama!” Fubuki screamed in joy. For these past two weeks, Do-S had trained Fubuki to love Orochi as much as she did if not more. “I really get to meet Orochi-sama today?”

“That’s right, now let’s get going,” Do-S said unhooking the chain from her bed and leading Fubuki out of her room.

As they walked toward Orochi’s throne room many of the male and female monsters couldn’t take their eyes off of Fubuki. To see a monster girl that looked almost like Do-S, was even more stacked than she was, and had a submissive attitude made them want to grab her and do all sorts of unspeakable acts towards her. Though for now, they knew that it was best for them to stay away. She belonged to Orochi-sama and they would have to be foolish to anger him.

“Orochi-sama I have arrived,” Do-S said, forcing Fubuki to bow with her as they entered the room.

“I can see that,” Orochi said as if he wasn’t interested, but the truth was he was. Seeing this woman who was staked in all the right places turned him on almost instantly. It wasn’t that Orochi didn’t like girls, it’s just that there weren’t too many of them that fit his tastes.

Do-S was one of those girls that just had everything he hated, even though she was fully devoted to him. Her sadistic personality and the fact that she was just too forceful turned him off.

As for the new and improved Fubuki, she was right in all the right places. Her breasts and ass were big enough so that he didn’t have to worry about his massive hands covering her entire body. Then there was that submissive attitude that she was emitting from the way she acted right now. He could tell that she would do anything that he asked without question and that made him hard.

Finally it was that shy but seductive look that she was giving him that really set the deal for him. He know that she would never be forceful with him, but would always be willing for more. He needed to have a closer look at the newest monster in his army to make sure that she met every qualification that he hoped she had.

“Bring her here,” he said without revealing his inner thoughts.

“Yes Orochi-sama,” Do-S said leading Fubuki over to Orochi before laying her chain to the collar on the ground before backing away.

“I have a question for you,” Orochi said to Fubuki who was now shaking in excitement after meeting the king that she has been told non-stop about during her “training”. “What do you like more, being a hero or being a monster?”

“A monster!” Fubuki said without hesitation. “As long as I can receive Orochi-sama ‘s love I do not need to be a hero! I love you Orochi-sama!”

Do-S was shocked by Fubuki’s comment. She knew that she trained Fubuki to love Orochi-sama above all else, but she didn’t think that she would say it! This fucking bimbo just cost them both of their lives.

“You love me?” Orochi said, as his face started to blush a bit, but no one could tell because of his dark skin tone.

“Yes I love Orochi-sama very much,” Fubuki said again without even thinking about the consequences of doing so.

“I see,” Orochi said with a smile on his face, but no one could tell because his face always looked very stiff. “Do-S you have done very well with this one. You are forgiven for your previous failure. Finishing preparing this one and make sure that she is ready for her first assignment. I would like to see her once it is complete.”

“As you wish Orochi-sama,” Do-S said before grabbing the chain to Fubuki’s collar and then dragging her back to her room.

“You bitch! How dare you!” Do-S yelled at Fubuki as she strapped her down to a chair facing the bedroom mirror. While she was happy to have survived she was displeased and broken-hearted that Orochi favored Fubuki over her.

“I’m sorry! What did I do wrong?” Fubuki asked, not understanding what she did. She did exactly what she was trained to do. Where did she go wrong?

“If Orochi-sama likes you so much then I’ll just make sure that he is reminded of me whenever he sees you,” she said Injecting Fubuki with a syringe and within seconds her hair grew all the way down to her ass, and then she watched in horror as her black hair turned into the same blonde that Do-S was.

“Don’t worry I won’t take away Orochi-sama's interest in you,” Do-S said to her as she started to braid Fubuki’s hair and then ended it by putting a black flower in her hair. “I’m just going to show him that if he can like one of us he can like both of us. We are sisters after all.”

“Sister?” Fubuki said repeating it back to her.

“Yes, it’s just like I explained before,” Do-S said bringing out a tattoo needle, before placing it onto Fubuki’s forehead. She then slowly began to tattoo a giant red heart on Fubuki’s forehead.

“Please stop! I don’t want this! Stop!”

Fubuki who had just realized what Do-S was doing grasped onto the last bit of her old self and screamed for her to stop. As her tears rolled down her face she realized that she was never the big shot hero she thought she was. She was just a dumb bimbo that loved to be punished. And what was the greatest punishment of all than being turned into a lustful masochist bimbo slut against your will?

Once Do-S was done with the tattoo she released Fubuki from the chair and pulled out another outfit that was similar to the one that she had made Fubuki wear during her training. Though what made it unique to Fubuki were the M’s that were on the equipment where the S’s on Do-S’ was. Fubuki changed into her new set of clothes without question. Once she did Do-S had two last gifts for her.

“From now on your name will be forever known as Do-M my new younger sister! And to cement this you shall wear this,” she said handing Do-M a mask similar to her own but with an M on it where the S should be.”

Do-M put on the mask given to her by her big sister, throwing away her past shelf. From this day forth the number 1 B-ranked hero was no more and the low-rank masochistic monster girl Do-M was born.

“Okay so let’s get started on your first assignment.”

-1 Week Later-

“Okay Do-M, we are finally back where this all began,” Do-S side to her bimbo sister. “Now I want you to find the hero Tatsumaki and defeat her. Do you understand?”

“Will this make Orochi-sama proud of me?” Do-M asked wanting nothing more than to be a help to her master.

“Of course, it will now go run along with a find he,” Do-s said shooing her along.

It didn’t take Do-M to find where Tatsumaki was. Even though she could no longer recognize that Tatsumaki was her older sister, she knew almost as if by instinct where she would be.

Tatsumaki was eating a parfait sundae at her favorite café when a monster girl that was similar to the one that kidnapped her sister came charging at her. For the past three weeks, these impostures wouldn’t leave her alone making it increasingly harder to find her sister.

“Tatsumaki I am here to defeat you in the name of Orochi-sama!” Do-M yelled at her as she got closer to Tatsumaki. “Prepare to diieee~!”

Tatsumaki who was in no mode to deal with this imposter used her telekinesis to launch her away and luckily for Do-M landed her right in front of Do-s. Do-S then took the unconscious Do-M back to the Monster Association headquarters.

“I can’t believe that you’re so weak!” Do-s said belittling Do-M who actually had the same level of strength that Do-s had. “Your too weak to keep as a combatant. From now on your number one duty outside of appeasing Orochi-sama will be to collect more slaves.”

“There are many good candidates pout there that will make fine monsters. Though now that we got that settled it’s time for your punishment,” she said cracking her whip.

“Aaah!” Do-M couldn’t help but more in pleasure at the thought of what punishment her sadistic sister had planned for her. Tonight would defiantly be a good night.
