Keiko, Chiharu's mother, bursts into the room, her breasts bounding wildly after their crushing collision with the door. She's winded from her long battle with the door which now lays crumpled and defeated on it's hinges. After catching her breath, she smiles over at Chiharu, "I just wanted to see how you were..." she trailed off, her eyes tracing the significantly enhanced contour of Chiharu's figure. Her mouth opened and closed for a moment, and Chiharu stood there, trying to turn away from her mother's incredulous look, but there was no angle she could stand without showing off one of her impressive new figures. If she turned her back, her noticeably swollen butt was showcased, and if she turned sideways it showed off EVERYTHING. After a few moments of struggling to hide behind herself, she pulled a sheet off her bed and wrapped it around herself.
"Mom...You're staring..."
"Huh? Oh! Honey, you've grown! A lot! I'm impressed, how'd you do it?"
Chiharu struggled to wrap the sheet more completely around herself, but it was difficult to make it cover both her swollen breasts and thighs. "U-uh, I don't know how, I had these tasty pork dumplings from Densuke at the club house, then came home. I started to get bigger before I even got in the house, but I think it's stopped now..." she said, lifting her breasts and squeezing them tightly to her chest. However, they were so huge that she can't reach around them to hold them well, and too soft for her to be able to really tell if they'd stopped growing...
"Yeah, they've stopped. I think... What am I going to wear with breasts like these? How will I even get around! I can hardly stand up! What will I tell Densuke?! Everyone else?" Chiharu collapsed in a sobbing heap, her breasts bulging out on the floor in front of her. The sheet was straining to cover her, stretched out like this.
Without a moment's hesitation her mother was kneeling beside her, stroking her back and bulging breasts soothingly. "Oh, Chiharu, it'll be alright, it's alright..." She whispered into Chiharu's ear, over and over, until she calmed down a few minutes later. Chiharu looked up at her with huge puppy dog eyes, striking Keiko's heartstrings. She helped her up, her breasts following her body slowly. They were gigantic, bigger than any breasts she'd seen anywhere, even bigger than her mothers. They reached down past her slim waist and rested softly on her swollen hips, firm enough that they still met in the middle when she stood up. Even standing still, her breasts shook and wobbled slightly under the sheet. Keiko was mesmerized by them again, and Chiharu had to snap her out of it again.
"Wha- Oh, right. I can help you. I'm sure I can find you something to wear. But I don't even know why you'd want to wear anything with boobs like that. Now Densuke will be all over you..."
The glint in her mother's eyes made Chiharu eager to change the subject. "Heh, let's find me those clothes. Let me guess, it's going to be a swimsuit, isn't it?"
"Yep! But, even to get that much, you're going to have to find out what made you so big!"
Chiharu sighed. It was just like her mom to only help when it would keep her the biggest. "Alright mom, but you're going to have to give me something to wear before I go anywhere."
"Fine, fine, alright." After about an hour of rummaging in Keiko's closet, they finally found a bikini that fit.
"Why would you have a bikini made this big?!?"
"Well, I'm hoping that I'll be able to fit into it once we find out how you got bigger."

Finally, they decide to get to the investigation. Where will they start?
#1 - The Eken Clubhouse: Since Chiharu only started growing much faster after she'd visited the clubhouse, that might be a good place to start.
#2 - Somewhere Else: There are all kinds of schemers around that could be responsible (Kirika, Kyoko, or Yuriko to name a few possible suspects), and there's all sorts of other places Keiko might think to look!
