[Draft] Maid Sibling (FemVali TG) (Patreon)

Grayfia held back a sigh as she watched party going on between the people inside, standing by the table. The party consisted of those mainly closer to Issei and his group, like Azazel and his young ward Vali. It was a small thing that her husband Sirzechs Lucifer, and Lord Gremory decided to do it for them.

A small smile formed on her face as she watched Issei dance with Rias. She could see the love between the two of them and was happy that they had managed to find the one they love. The other girls nearby were watching eagerly for their turn to dance with him. She was happy Rias got the first dance, more so because she was her favorite and the one she was closest to.

It was good for them to relax after all they had been through. It was almost frightening how much they had done in so little time. They had fought high-class angels, ultimate class beings, and gone on many dangerous adventures that they shouldn’t have. She worried what might happen to them next. They had come to close to death more then enough times, and she would be happy if they didn’t have to keep escaping it by the skin of their teeth.

She hoped that they wouldn’t have to keep going through trial such as these, or at least have some more time to relax. They were still young and should be allowed to enjoy their youth and relax. Not like when her and Sirzechs were young and they had to fight in the war.

At the very least she was happy that her son Milicas was able to relax and enjoy his childhood. She wasn’t sure if she would be able to handle it if her little boy had to grow up and face such hardship. Hopefully by the time that he gets older, the events of this time would be settled and he wouldn’t have to go through the same thing.

Grayfia picked a glass of water on the counter and quickly drank the contents. Her eyes quickly widened as her throat burned and the liquid settled in her stomach like an iron weight that had rested in her stomach. The glass slipped from her hand and clattered onto the floor. The last conscious thought that she had was that she had accidentally drunk alcohol and hope that she wouldn’t make a fool out of herself.

Unknown to many except those closest to her, the Strongest Queen had one weakness. She could not handle her booze. It had been something those closest to her had made sure to do their best, lest they wind up on the receiving end of what the drunken queen had in mind. She could’t even handle one full can of beer without getting drunk. A meer sip was the equivalent to her of a full can. It was why she maintained a strict behavior and watched herself at a party and made sure to avoid alcohol. It was also why Sirzechs and his peerage had done their best to be sure.

A deep haze came over her mind as if she had just been hit in the head by Sirzechs during one of their training sessions. The posture that she had mere moments ago was completely gone. A dopey smile formed on her face that would have thrown anyone off that had seen the expression on her face.

She stumbled as she looked around, everyone too focused on what they were doing to pay her any real mind. Sirzechs looked at Issei enviously as he danced with Rias, making a frown form. If he did anything to ruin the moment between the two of them then she would need to give him a punishment worse then any she had done before. The thought of her husband and love for sisters came rushing forth in her mind. Many times he had gone out of his way and made things embarrassing for her. There was still the whole security camera debacle that he had hid in her room back when she was younger.

She couldn’t understand his and the Leviathan’s action or why they acted like they did with their siblings. It couldn’t be that good could it? Perhaps she would be able to understand if she had a little sibling of her own! Her mouth dropped as a revelation came over her. She already had a little brother, but they weren’t close.at all close and he was nowhere near adorable as he used to be. Her ditzy mind tried to figure out what could make it so different.

It had to be a little sister was the key. It was the only thing that made sense to her. There was something about having a little mini-me on the female side. Still, it wasn't as if she could perform a test with a little sister. She never had one herself and there was no way that she way she was going to get her brother here and test it. Rias was a little sister figure, but she didn’t feel the way that her and her sister. It might be a biological thing. If that was the case then it would make sense.

Still there was a way to see if it was a biological sibling thing. It might be too late for her to have a sister naturally but that didn't mean that she could not make one. She just needed to fimd the right person, and that boy was the perfect subject to make it happen.

The drunken maid looked around the room, her mind wondering who would be the perfect person to use for it. Issei might like it just for the simple fact that he would be getting a set of boobs of his own, but with all eyes on him it would make it impossible. Her husband was an automatic no, just because she liked him but also to avoid weirdness that would happen if little Milicas was nearby and wonder where his daddy went. All of the other older guests were a hard no as well. They were all far to important and if something happened to them while they were here then it could be seen as an incident.

She noticed in the corner out of sight from most was Vali Lucifer, looking bored. He was off to the side drinking from a glass. He looked bored as if he would rather be anywhere else than here.

The drunken silver-haired woman stared at the silver-haired young man as if she was trying to find the meaning of life as she studied him intently. In her head, she was already going over the math inside. He had silver hair just like her’s, though his was shorter and more spikey. He was a boy, but that wasn’t an issue. That was something that she could easily rectify herself. Their faces were different, but it could easily be altered to make it more like hers.

She brought her hand up and slammed it down onto her fist as a grin formed. Vali was the perfect boy to get a little sibling set up. He already looked like he could be a younger sibling for her with the hair. It wouldn’t take too much else. Just alter the face, give him a curvy woman’s body and then bam they looked like they could be siblings.

The first thing she had to do was get the two of them alone. She couldn’t afford to have any pesky troublemakers interfere with her work, especially if it reached a critical point. Then they might throw a fit, reverse her attempts, and then she would be back at square one.

The maid kept her eyes on the young man waiting for him to do something. It would look strange if she pulled him off to the side and tried to talk to him. They didn’t have any personal connection like with Issei. The only thing she could do was wait for the young to move. It could take all night, but she would get him to see why all craze for the little sibling. Though she had her doubt that it would take to long with his type. Battle maniacs like him couldn’t stay in one places long enough, especially places like this.

Grayfia frowned as time passed. It was annoying that she had to wait for this scamp to do something. A small squeal left her mouth as she saw him place his drink down and leave the room. This was the chance that she had waited for. She stepped forward, her steps far heaving than they normally would have been if she wasn’t as drunk as she was.

Despite her intoxicated mind, her senses were just as sharp as they had always been. There wasn’t anyone nearby and with the party, all the focus would be there. A sudden pulse of magic wouldn’t get attention.

She followed after him, looking at the crowd to make sure that no one could see her. The last thing she needed was to deal with some pesky people who stumbled on something they shouldn’t. It wouldn’t be a problem, but it would just an annoyance that they needed to deal with. When she made it to the door, she looked to make sure no one had noticed her. Grayfia let out a small titter as she moved, proud that her steal skills were

Of course, the real reason was that everyone was already focused on someone else. They would have clearly noticed her if they weren’t so focused on Issei. The young was currently being pulled in all directions by his various love interests, who all vied for the next dance. Giving reasons why they should as they pulled on various parts of his body.

She wondered where he was going. She doubted the young man was stupid enough to try and do something when there were so many powerful people in here. Actually, on second thought, he just might do something if it meant a good fight. He entered one of the rooms and she poked her head through the door to see what he was doing. The young man let out a tired sigh as he leaned against one of the walls.

Grayfia smiled and giggled. This was the perfect place to begin making her new little sister. The woman waited patiently like a cat waiting for a mouse to come out of a hole in the wall. Best to let him get settled and relaced first before she did what she had to do. That way he’ll fall a little easier when she does what she needed to do. With all the control that her drunken could muster she called upon all of the self-control and professionalism that she could and stepped into the room.

Vali turned and saw the older maid standing there. The young man opened his mouth to say something but the look in her eyes and devious happy smile made him freeze. He had never thought he would see it on the woman’s face with her reputation.

“What do you want?” Vali asked.

The last thing he needed was for something to happen and suffer some sort of punishment with Azazel.

The woman stood there and didn’t say anything. He stood there waiting for her to do something, anything, but she stood there, like a tree swaying. The White Dragon Emperor wondered what was going on with her.

“Didn’t you hear me? Is there something you want?” Vali said, annoyed. He had wanted some space away from everyone at the party so he could relax. He wasn’t meant for these events where people were meant to talk and all. He would rather be training or fighting someone strong. The only reason he had come was that Azazel had pretty much dragged him here.

Vali opened his mouth to speak, but before he could do anything she held him down and started to use her magic on him.

“Ehh!” the man cried and tried to shove her off of him, but she straddled his waist and made it much more awkward.

A sloppy smile formed on her face that further unnerved the young man. She raised one of her hands and a magical circle formed that made the man young man’s eyes widen. The White Dragon Emperor moved to summon Divine Dividing, but before he could bring it out, he gasped as it suddenly felt like it had a block. The strength that he had in his body left him and his limbs suddenly felt heavy.

Grayfia giggled and clapped her hands, the spell already performing everything that it needed to do. Not many knew but she had such control over her power that she could alter her age on a whim if she chose. Changing someone else was well within her power, but something she would do in her normal state of mind unless it was a punishment. Like if her husband wasn’t doing his work or if they were in the bedroom.

“Get off!” Vali screamed and pushed her off.

The drunken Strongest Queen stumbled back and fell onto her butt. She blinked and looked around, almost as if she was a cat watching a laser pointer.

“Who are you!” Vali demanded glaring at the drunken woman. “What did you do to the real Grayfia?”

“No, I'm Grayfia,” the woman said petulantly, which made Vali immediately come to the conclusion that she wasn’t who she said she was. There was no way that this was the Ultimate Queen. Her personality was completely different. This was the power that the real Grayfia had. It wasn’t something that a person could fake so easily. His jaw felt like he had been socked in the face by Issei or Azazel during one of their training sessions.

“Just what happened to you?” Vali said as his head ached as if a headband had been wrapped around his head. The shape of his skull altered and started to look more feminine as his face rounded. As his cheeks rose, his face softened. It lost the hardness that had been on it before. His nose got a little smaller and became a sharp grecian nose and his lips grew a little larger.

Any small scar or imperfection that he might have had gone. When his face finished changing it looked similar to Grayfia’s, but was younger. He was just as beautiful as any of the girls in the main hall where the party is going on.

“Oh!” She cried happily and clapped her hands.

Vali looked down at the older woman as if she had just told him that she wanted to give him a personal lap dance. Whenever he heard of the Strongest Queen he had been told how stern and serious she was. Not even her own husband, the strongest Satan could stand against her and hit him without fear. It was almost as if she was somehow else entirely.

Even if she wasn't fully here, he doubted that the spell wasn’t a fizzle. Someone on her level of power would be able to maintain their concentration no matter how addled their mind might be. Anything less just wouldn’t be right for someone on her level.

“What did you do?” Vali demanded.

“I used a spell,” Grayfia said, almost happily.

The young man ran a hand down his face and then scratched at his clothes, wondering what poison could cause this. This was going to be more annoying than he thought it would be.

His frame got a little smaller as he changed. Underneath his attire, the body hair that he had on his body vanished as the hair he had gone back into his body. His body slimmed down as if he was losing muscle and fat, his clothes hanging slightly off his frame, but he never noticed. The way the woman was acting like a ditzy drunk had take

The young man sighed as he pulled the woman to her feet. The last thing he needed to be suspected of was being the cause for why she was acting the way she was. The woman took his hand without issue and let herself be pulled up. The woman zoomed up and crashed into Vali making him stumble back. He blushed at feeling her massive bust collide with his chest and blushed. The silver-haired young man moved to push her away, but just like before

Vali quickly grabbed the young women before she could fall back and let out a sigh. He wasn’t using even a fraction of his full strength and yet she was acting like she was. Whatever was affecting her like this really did a number.

He didn’t notice from the way that his hands were against her clothing, but they started to get smaller. His uneven nails started to clean up. They grew longer and refined into even cleanliness. The changes spread to the rest of his fingers which started to get smaller and look more fitting for his refined nails. They quickly became small slim digits perfect for a woman to have. The calluses on his hands from years of training got smaller as if he had been using the finest lotion he could. The rest of his hands changed as well, his slimmer arms became even thinner, as the muscle refined.

His feet started to get even smaller and lose the masculinity that it had. Just like his hands, his toes refined and the rest of his feet followed, leaving with small dainty womanly feet that now didn’t properly fit his shoes.

The new thick thighs rubbed against his shaft and he could feel the erection that he had farm and grow in strength. It only made the heat between his legs even worse then it already was. It continued to build and there was no way that he could think to alleviate it.

The young man blinked at the sudden heat between his legs and looked down wondering what was causing it. His eyes widened at the sight of thick sexy thighs. The silver-haired boy stared. He couldn’t possibly have thighs like this. He had to be seeing things wrong, like a trick in his vision that made them look bigger. He slowly moved his legs and flinched at the soft sensual skin that he felt rub against his wood.

“What?” Vali said with a pale face. “What is happening to me?”

“Oh your becoming my sister!” Grayfia said happily.

“Sister?” The half-devil said.

“Yuppers!” The Strongest Queen declared happily, even clapping her hands together.

Vali shuddered as hair grew longer, tickling his face, and neck as it did. The messiness of it cleaned up as if someone had taken a comb ran water through it and started to clean it. Locks of hair grew out and moved as if someone was holding it and moved to form two small braids.

“You have to change me back before whatever is happening finishes!” Vali demanded, glaring at the woman.

“How?” Grayfia said.

“What do you mean how? You’re the one who cast the spell!” Vali exclaimed. He tried to keep the disappointment and anger from getting the better of him, but it was proving to be an uphill battle. Especially with what was happening to the rest of his body. “Is this only going to affect my body, or will it also affect my mind?”

“I think both,” Grayfia said slowly, as if she wasn’t sure herself.

Vali wanted to slam his head against the wall. How could his sister be this forgetful with her own powers and how they worked. The thought made his eyes widened and he shook his head. No that wasn’t correct. He never had any connection with her before this and reminded himself that it was the work of the magic.

The young man hissed at a pull between his legs. He looked down and noticed his aroused hill was getting smaller, despite how pleased he was. The young man quickly realized what was happening to him.

“No!” Vali cried. He tried to call upon his own magic or his Sacred Gear again to fight the power that was affecting his body.

The hill that respensted his masculinity continued to get smaller and he wasn’t sure what to do. He spasmed as his already sensitive manhood continued to rub against his lovely thighs. He bit his lips as his dick got smaller. The changing young man spasmed as his privates went into his body and a new pair of moist lips took their place.

Her thighs quivered and she gulped as she tried to steady herself, but it was impossible with how much her mind was addled and the growing heat. An erogenous moan left her mouth that would have made men cream their pants and wish they were the one to cause it.

The new young maid clenched her butt cheeks together as they started to grow out. Her behind swelled as if the rubbing was a trigger and the longer she did it. The more it would grow. Despite the change in size it hadn’t lost any of the muscle that had been developed in there. In fact, it only served to make the growth of her rear more pronounced. She mewled as her underwear dug in between her cheeks and rode her rear. The strain on her pants started to settle as the growth of her hindquarters slowed. After a few seconds that seemed like hours, her behind had become a huge round bum that strained the back of her pants, making up for the lack of height.

“Oh you like that butt don’t you?” Grayfia giggled naughtily as she started to spank it.

“Si-Sister!” Vali exclaimed as embarrassment went through her. “Ahh!”

More heat went through her body that only increased the pleasure she felt and centered on her chest. It built up and she looked down the front of her shirt and reeled at the sight of two large erect nipples that tented the front of her shirt. An embarrassed blush went through her as she tried to think of the best way to counter the magic.

Vali moaned again as if someone had started to rub her chest and play with her nipples. Two small lumps formed together and started to grow, pushing her nipples further out. She wondered how her shrt hadn’t been cut from how hard her body was. She shivered and wasn’t sure what to do. Her first instinct was to tear her shirt in half so it wouldn’t bother her anymore, but that would mean showing them off to her sibling.

“Don’t smack yourself,” Grayfia chided with a stern face that was befitting the older woman’s known reputation. “You are better than that, and could make your face bruise.”

“That is preferable!” Vali growled as she rubbed her thighs together.

Vali watched in an aroused haze as her chest ballooned. The more her breasts grew, the more the front of her jacket was pushed out as the roundness of her breasts became more visible. It would have been a sight that Issei, Azazel and many other perverts would kill to see. She panted with aroused glee. Pale cleavage started to peak through her top making her whimper as they continued to grow seemingly without abandon. Her erect nipples rubbed and scratched harder against her shirt.

“Oh you’re getting so big!” Grayfia said as she drunkenly grabbed the enlarging mounds on her sister’s chest and squeezed.

Vali’s mind clouded further as the heat altered more of her mind. Her past was changing, the earliest parts were the same with her grandfather killing her parents and running away, but what came after was different. She had always been a part of the Gremory household ever since she had been found by Grayfia. Grayfia had taken her on as her younger sibling. She had been taught how to use her powers and was raised along side Rias.

The growth of the new girl’s bust slowed as the haze in her mind grew. She could vaguely recall her original past, as if it was a dream that she had just woken up from her. Her breasts finished growing when they became an immense F-cup that rivaled the Gremory heiress’s own bustline. She could feel every ripple of her tit-flesh as it touched her sibling’s own. It was as if someone was playing and teasing every little part of her tits.

Grayfia squealed gleefully at the sight of her new transformed sibling. She pulled the younger woman into a bone crushing hug that made her squeal, their immense busts getting squished together and forming a sight that many men would have killed to see.

They were not done yet, not until they fixed her sisters clothes. Using more of her magical power she began the process of changing her now ill-fitting clothes into something more suitable for a younger sibling of hers.

Her drooping pants legs moves closer together until her thighs touched each other. The moment they touched, her pants legs merged together and started to form the bottom of a short dark blue skirt. Her jacket turned white and and zipped around the front of her body. The zipper and pockets merged into the coat as if they were being sewed shut, and left no trace. Once all the pockets and features of the jacket were gone it shrunk around his waist and became a white apron. When the clothes finished changing the former descendent of Lucifer now stood in a maid uniform, similar to Grayfia’s owThe drunken strongest queen leaned back and looked over her new sibling, a squeal escaping her as she cuddled her again with greater adoration. Now that she had a cute little sister of her own she could certainly see the appeal. It was almost like having a mini-me, especially with the similar color and outfit.

“Oh Valiere you look so perfect,” Grayfia said as she rubbed her face.

The young girl blinked. Sensations went through her body that aroused her as new thoughts filled her with embarrassment. Her breasts, especially her nipples rubbed against her own. The same thing was happening to her ass. The frustration and embarrassment within her swelled and she looked around to make sure that no one was seeing this. It was a little difficult considering how distracting her sister was, but to her relief there was no one else in the room.

“Sister enough!” She cried.

The young woman blinked at how far she had went. She hadn't used that much strength to do so. Now that the sudden panic from how odd her sister was acting was gone she could fully take in the situation. She stepped closer and no

ticed the vapid look in her eyes. The new maid looked her over and sniffed her breath. The moment she did, she recoiled at the faint smell of alcohol that hit her nose.

“Did you have alcohol again?” the younger maid sighed.

A slight hiccup left Grayfia’s mouth and she frowned. The young woman raised her hand and the older woman’s eyes followed it sloppily. She leaned forward and could smell the faint smell of alcohol on her breath. If there was any doubt in her mind that she was drunk they had shattered into glass shards.

“How did you get drunk you're usually so good at this?” Valerie said, wondering how or who could have done this.

“I just grabbed a glass and chugged it down, it was the strangest thing it was water Im sure,” Grayfia slurred.

The younger woman sighed and ran her hand down her face. She quickly looked around, making sure there was no one around. It was possible that it was an accident, especially with how much food and drink were here.

“Let’s get you some water and some food in you. Maybe some coffee to,” Valiere said as she took her hand and dragged her out of the room. Her mind scrambled to think of everything that she could to get her sibling sober quick.

The strongest queen sloppily followed after her new younger sibling, preening over how she looked. The younger maid flushed as she did, mentaally recounting how far the kitchen was and how long it would take to get there. She couldn’t let anyone know what had happened to her.

The last thing she needed was for her husband, or the Leviathan to see her like this. The moment they did they would all team up and the world didn’t need those three sis-cons getting together again. She shivered as nightmares of the three of them forcing them to wear outfits they had chosen for them.

Her sister might be sorry about the whole thing and apologize to her profusely afterward, but it didn’t make up for all that she had suffered during it. Besides the other two would still have evidence of what the three of them had done. At least until Grayfi sobered up and she would get rid of the stuff. At the very least her sister made sure to destroy any embarrassing stuff at her behest.

And while she was, try to find a bra for her chest. She didn’t know how, but apparently she had lost her’s somehow and she was sure that Grayfia was the cause. She just hoped her sister, whatever she did with it, didn’t leave it out for someone to find.
