[Fluff]

"Alice? Isn't it weird how Mom hasn't been by in a while?"

"Which one."

"The one that was Dad once."

"Even back then, the times he came by were far and few between. Whatever she's doing now must keep her even busier than then."

The idle chatter between two siblings filled the rich kids' house as they sat across from one another in their spacious living room. Ever since they had grown up to be clever young children, they were able to keep themselves occupied and out of trouble, to the point where their parents had given them a level of autonomy that was unexpected for kids their age. Especially since said parents were always so unfathomably busy.

The young boy, whose words were more cheery, was Albert Grimwald. A pink-haired youth whose kind heart was so unlike the rest of his family. But it was that very same heart that made them spoil him rotten. He got anything they asked for, and he returned their kind behaviour with even kinder smiles and actions, because that was what he thought was important for them.

His sister, whose expression was a lot sharper and her words a lot more distasteful regarding her family, was Alice Grimwald. If her brother had inherited all of her parents' best traits, she had inherited the worst ones. Which made her a dangerous individual, and let her pamper her brother with schemes that would keep him all to herself. Schemes that had failed several times over, but she had maintained her menacing reputation despite this.

"Yeah, but she should come by at least once. I miss her." Albert sighed as he kicked his legs back and forth. "What about Mom? Didn't Mom say the two split?" He asked, tilting his head a little.

"Knowing Mom, they didn't split. She just turned her eyes towards somebody else." Alice explained, grimacing a little. For all of her problems with Suzaku, she wasn't an immediate fan of her Mom's new husband. Even if he had tried to spoil them just like her Mom did. "Why do you want Mom to stop by, anyway? Don't you have exams to study for?"

"Because I miss herrrr!" Albert moaned as he flopped onto the bed and sighed as deeply as he could. "I just wanna see herrrr. She's always been so nice to us..."

"It's not like she's going to show up at our door when you want her to show up." Alice said as she idly turned her head towards the door, raising an eyebrow to make sure she didn't tempt fate. After a minute of staring, she turned back towards her brother. "Call her if you need to. I'm sure she'd pick up for her baby boy-"

Fate played exactly the kind of trick on her that she expected, as the door opened not many seconds after she had turned away. And standing there was a girl that looked almost identical to their Mom, though it wasn't hard to notice the subtle differences in their looks that made it clear she was a different girl altogether.

"Mom!" Albert, however, wasn't very clever. He was a very kind soul, but he wasn't a smart one. So he didn't notice that the girl standing there, with the short and stacked frame, wasn't his Mom as he dove towards her and hugged her as tight as he could.

Alice stared for a few seconds as her brother rubbed up against the mysterious near-doppelganger, her eyebrow twitching as her distaste for the girl rapidly grew. If there was one thing she hated, it was seeing her brother obsess over another girl. Even her Mom wasn't exempt from that hate, but since this girl wasn't her Mom... Her hate was all-too-justified.

The girl with the white hair and the white uniform looked down at the pink-haired boy, and she smiled as she slowly ran her hand through his bushy hair. "You really are as cute as Mama said." She whispered in a gentle tone. Even somebody like her couldn't help but find the boy utterly adorable and captivating. If he wasn't her Mom's son, maybe she would've had a bit of fun with him....

Both of the two siblings froze as they heard what the girl said. "Mama?" Albert asked, as he slowly pulled away from the girl. She knew about their Mom, but she called her Mama... Was she a siblings that he didn't know about? Did Mom get pregnant and didn't tell them? No, wait, she was a bit older than them, so... Did she just keep a secret?

Alice, meanwhile, felt her rage rapidly building. She had competition. Direct competition. And that meant that she had to do something about it, the floor cracking ever slightly as she got closer. "Mama, you say?" The venom was visibly dripping from her mouth. Her anger manifested itself, and if she didn't calm down, she would be having more than a heated moment.

"Mama, yes." The girl said, as she gently curtsied before the two siblings. "Gaia Grimwald is the one I call Mama. After she made sure that I wouldn't get in her way. I am Mikai Grimwald, her precious and adorable daughter." Her delivery was a little rigid, and it definitely seemed like she hadn't always been this way... But she did look the part of a daughter, perhaps too accurately.

It didn't take long for Alice to put two and two together. She had heard of the girl. A heroine that had been fighting back against willpower-empowered monsters. A heroine with about two brain cells and one of them always spent the day sleeping. A bright girl that would never let evil stand as long as she lived. And here she was. Reflecting one of the most despicable women in the world. And trying to act like she was one of her daughters. When the real daughter of Gaia was standing right in front of her.

Albert, on the other hand, just smiled as he took it at face value. "Oh, wow! Mom never told me I had a bigger sister! Alice, isn't she pretty?" He wasn't at all phased by this revelation. He even chose to ignore the foreboding words about what she had done to end up this way. He just thought that his new sister, Mikai, was really pretty and nice. Just like Mom!

"She's certainly gorgeous." Alice said with the venom dripping through the cracks between her teeth, as she came to a standstill right behind her brother. "But why did Mom choose to send her, when she could've come all on her own? Why send a sibling without properly introducing us?"

Mikai smiled, as she carefully pushed her new brother out of her way. "Mama thought it would be best if we got acquainted without her being present. To let your reactions be as raw as possible."

Before Alice had the chance to reply, she suddenly found the older girl's arms pulling her close, pressing her up against her rather excessive bosom. Just how big were those breasts?! They were the size of basketballs.... no, they were bigger. And they were sucking her in too, trapping her in that awful chasm.

Albert watched with a stupefied expression on his face, but he didn't stop her. There was something... really cool, about the way that she managed to deal with Alice. Not even his girlfriends had a good way to stop her.

Alice was practically screaming with rage inside that breast valley, but it didn't get her anywhere. All that happened was her body struggling to get free. A painful and fruitless struggle, because her sister would not let her go anytime soon. Not as long as she kept being such a bratty little thing that hated her at first sight.

"Feisty. Mama warned me about your temper. How you had been so terrible with Mama's old wife." Mikai said, as she slowly moved her hands further down. Reaching down to grope away at her rear, to squeeze into those firm cheeks. Not nearly as firm nor as large as the older girl's, but comfortable and thick enough that it was hard to get her hands free after digging in.

"Is she going to be okay in there?" Albert asked, tilting his head a little. He was honestly worried, because there was a bunch of angry steam rising out between his new sister's breasts. And he knew that once Alice got heated, it would be very hard to stop her from breaking something. He managed to stop her from breaking at least a couple of bullies' backs when he was still having trouble in school, but those guys never bothered him again after what she had done. If anything, he was less worried for his old sister and more his new sister.

"If she's a good girl, she'll be fine. But if she's a bad girl, who always gives Mama trouble..." Mikai started talking, before pressing her breasts down on the pink-haired girl's head, the pressure causing the muffled and frustrated groans to increase in both tempo and frequency. "Then Mama gave me permission to discipline her. Make her realize how she can use her body in much better ways..."

Alice wanted to do nothing more than completely and utterly break the girl that had trapped her in this sweaty prison. She couldn't be her sister. She just couldn't. And yet, the way she firmly grasped and kept control over the situation was something she could've only learned from their Mom. She always did this when she got angry. Keeping her from exploding, only to defuse her with love. This just wasn't the same kind of love, this was the kind of love that was nothing more than twisted condescension.

And yet she couldn't do anything against it. The more she listened to the awful girl, the more her body heated up. She felt her natural strength and feisty nature being suppressed, especially as those foul hands dug into her body. How did she know her weak point? More than that, how did she know exactly how to stop her? It wasn't fair...

As Alice's body slowly stopped struggling, the bustier sister giggled. "It seems like Alice understands who's the eldest sister in this house." She said, pinching those cheeks a little more as she looked towards her brother. "Does she always do this, brother?"

"Kind of." Albert said, smiling softly as he noticed the steam dying down. Thank goodness, they weren't going to fight. "I can't do what you just did, but I usually make her calm down by making her a big meal! Then she's all blushy and squirmy when she eats!" He chimed, proud of the few skills that he did possess.

"Why don't you make us a nice big meal, then? I trust that you can cook for three? Mama did sing praises about your cooking." Mikai chimed, and her little brother quickly ran off to satisfy her request. He wanted to impress her, just like he wanted to impress his Mom!

As he departed for the kitchen, Mikai pulled her younger sister out of her bosom, cupping her chin with her hand as the blushing girl looked back up at her. "Dearest sister. Mama wouldn't want us to fight. And I don't want to see you fuming for long either. So I propose a deal."

"...I'm listening." The calm, yet still pouting Alice replied. She wasn't going to put up another fight, not after being trapped in between that sweaty set of mounds.

"Why don't we share our dear brother? You, I, keeping him company in bed and spoiling him rotten with our bodies. I'm sure he's more than capable, from what Mama told me about his hobbies. He might even put Papa to shame..." Mikai mused, a little bit of drool running down her chin...

"You'll find him more than capable. And if you pass out before he's done, I'll be keeping him." Alice replied, and her new older sister accepted those terms with a soft nod.

Alice grinned. Oh yes, things were going to turn around... And maybe she'd see that new sister of hers completely destroyed, after being outpaced by her brother. Then she could keep him all to herself, and she could get rid of this infuriating girl...

Little did she realize, Mikai would give both of her siblings a taste of the appetite that her Mama had given her, following her transformation into her daughter.
