Brooke's Shower Accident 4

Both sisters decided to get up around 7 the next morning. They knew what was ahead of them for the day and knew they would need at least a few hours to recover from it. Brooke had agreed to fill her belly once more, only this time would be with Allie doing the same with her.

Brooke woke to the sound of her alarm clock and got out of bed. After undressing, she quickly put on a pair of black spandex shorts and a matching sports bra. "I don't want to stretch out another one of my shirts again..." she thought to herself while looking in a mirror before heading to the living room.
Allie was already awake and dressed in similar spandex shorts to her sister along with a light blue t-shirt and her hair tied up in a ponytail. She sat on the sofa with her one hand holding up her shirt a little and the other feeling her once again flat stomach with a worried look on her face.
Brooke walked up behind her and put a hand on her shoulder. "Morning sis!" She said with a slight smile. "You're up early."
With a scowl, Allie responded "Well yeah... I woke up at six this morning was in the bathroom for nearly 50 minutes!"
"Well, you should have thought of that before. I had to do the same thing twice already. And we both are gonna be doing it again tonight." Brooke retorted back with a chuckle.
Allie sighed and stood up. "So... How are we going to do this? We only have the one shower hose."
"You're right... I didn't really think of that..." Brook said, slightly confused before suddenly getting an idea. "Actually... We DO have two hoses."
Allie raised an eyebrow as she waited for her sister's answer.
"Two... garden hoses... In the back yard..." Brooke finally answered.
The younger sister sighed again and made her way to the back door and opened it. "At least we will still have privacy in the back yard."
"True. Let's go ahead and get started then." Brook said as she followed her sister outside to the back yard.
The two of them each grabbed one of the two hoses that were conveniently set up next to each other.
Brooke looked at her sister next to her, who was looking at the hose and down at her midsection again. "Are you ready?" She asked her.
Allie nodded and put the hose in her mouth with her hand on the faucet as her older sister did the same. Both of them spun the faucets, turning both hoses on full blast right from the start, causing the water to begin flowing through the hoses.
The two sisters looked at each other and then down at themselves to see their once flat bellies start to push out a little. Allie already felt really full while Brooke was only at the beginning stages of her fullness as she had gotten more used to being filled up.
It wasn't long before Allie's shirt began to roll up her expanding middle and bunch up beneath her breasts. She looked over at Brooke, who seemed to make the smarter decision of only wearing a sports bra. Even with the hose in her mouth, Brooke still managed to point at her sister's shirt and make a subtle grin to poke a little fun at her.
Neither one of them had planned on how far they were going to go. But both of them knew that they had to go farther than either had gone before since it was their last day with the house to themselves before their parents returned back home.
Allie was starting to get worried. She had no idea how much her sister was going to take in, but at the same time didn't want to be bested by her. She saw Brooke peer over to her and Allie tried her best to fake a grin in hopes to fool her that she wasn't worried.
Brooke looked away from her sister and back down at herself. "Allie doesn't seem worried at all. She actually seems quite confident..." She thought. "I can't let her beat me! I'm the older sister here!"

At that point, the two of them had taken in enough water so their bellies now started to hang down in front of them. The weight of all the water was starting to be a little much as the two of them hadn't gotten chairs. Allie had to resort to using both of her hands to holding up her belly while Brooke didn't quite need to yet.
Allie felt odd, holding her expanding stomach in her hands. Brooke had to help carry it the night before when she went to bed, but this was different. Water was still flowing into her and getting heavier by the second. She winced slightly and saw that her sister now had to start doing the same.
Brooke grasped her belly from beneath to apply leverage. She too felt awkward and a little queasy from within but she continued on.

Eventually, they reached the point beyond any amount either of them had taken in before. They both had to let go of their bellies as they could now barely touch the grass under them. Their skin started to turn a pinkish color. Brooke looked over at her little sister to see her wincing, clearly in some pain, and motioned a pointing gesture at the faucets, trying to ask if she should stop the water. Allie, with a defeated look, nodded in agreement.
The both of them tried to move to the faucets but realized the weight of their bellies was too much for them to move. Brooke looked at Allie with fear in her eyes and Allie returned the gaze. They pulled and tugged as much as they could before the constant pulling on their heavily expanded tummies became too uncomfortable.
Allie gave up and just closed her eyes with her head down. Brooke gave it one last pull before going too far and falling forward. She landed on her own belly, sending a surge of water through her, nearly making her puke if only the force of the hose wasn't so much.
Brooke's hands and feet could almost no longer touch the grass and tears began to roll down Allie's face and drop down onto the growing glob of flesh that was her own tummy before she too fell forward onto it, not at all able to reach the grass.

Just as they thought they would be stuck there until their bellies gave out, they heard a voice. A voice only familiar to Brooke though... "Hey! What are you doing Brooke? What's with the balloons?"
