Hanabi leaned back against the bath's wall with a happy sigh. Her plan had worked! Her wonderful, not to mention absolutely delicious, big sister was now curled up nice and tightly within her stomach. Her big sister whom she had looked up to for so long could do nothing but lay in wait for the digestion that would soon follow. Hanabi smiled to herself as she let her hands pat and rub her sated belly, the bulge of which took up nearly her entire lap. Licking her lips, Hanabi leaned back and relaxed further as her hands continued to kneed and rub her sister-filled stomach.
The full feeling Hinata left her, along with the heat from her hot bath water was, however, making her drowsy. Feeling that simply closing her eyes for a few minutes couldn't hurt, Hanabi allowed herself a few moments to enjoy the feeling before unintentionally dozing off completely.
-Timeskip-
Hanabi awoke some time later; roused by an unusual aching sensation within her stomach. Hissing as the dull pain started to fully register with her sleep-clouded mind, she drew a heavy, uneasy breath, blinked open her bleary eyes, and turned her attention to her midsection.
To her mild surprise, her stomach was still just as bloated as when she had first eaten Hinata. Hanabi figured she hadn't been sleeping for long if the weight of her meal hadn't diminished in the slightest. Looking at her hands, however, made her think otherwise as they seemed to be quite pruny. Placing one hand on her stomach, Hanabi was just about to stand and exit the bath before her belly rumbled beneath her soothing fingers like an underground tremor, more felt than heard. Giving a gasp, Hanabi clutched her stomach and curled around it with a pained groan as the ache flared into full-on pain. Hanabi couldn't quite believe it, but her sister, her sweet and delicious sister, was causing her indigestion. If that wasn't enough, as the pain tapered off for the moment Hanabi felt the telltale signs of movement inside of her belly. Seemed Hinata hadn't given into her stomach yet and was stubbornly moving around as much as she could to further upset her belly.
Deciding she'd deal with her sister's insistent squirming later, Hanabi took this chance to slowly exit the bath, clutching her aching belly the whole time with one hand. Despite the extra weight and change in her center of gravity from Hinata digesting inside of her, Hanabi still managed to exit the bath and make it halfway to the doors before collapsing. It wasn't a lack of strength that caused the young Hyuga to falter though. No, the fault lay with her stomach which had chosen that moment to let loose an agitated groan as pain shot through the digestive organ once more. Thankfully for Hanabi, who was currently curled up around her stomach and whimpering pitifully, a voice rang out from the other side of the door.
"Hanabi-sama, is everything alright?"
Hanabi had never felt so thankful to hear her maid and caretaker's voice. Hanabi opened her mouth to answer and complain about her tummy troubles, only for a loud belch to escape her instead. Thankfully, Natsu seemed to understand well enough that Hanabi needed her.
"Hanabi-sama, I'm coming in." With those words mind, the door separating the bathing area from the changing room slid open revealing Natsu, who was clad in nothing but a towel. Stepping inside the bathing area mind, the green-haired maid and caretaker of Hanabi was greeted by the sight of her young charge laying nakedly on the ground and clutching a massive and greatly distorted belly as whatever rested within the dome of flesh squirmed frantically. Despite the highly unusual situation, Natsu seemed to only be momentarily surprised before she pushed it aside.
"Oh Hanabi-sama," she began with a tired sigh. "I did try to warn you that your belly wasn't yet ready to handle Hinata-sama, didn't I? Suffering a bad tummy ache seems only fair for not listening."
Despite the light scolding mind, Natsu calmly helped her charge to her feet and carefully walked her back into the changing room where she quickly set Hanabi down and striped off her own towel so as to dry off the overstuffed girl.
Feeling her stomach ache settle for the moment, Hanabi used this chance to sneak a look at her caretaker. Even after knowing the older girl for her whole life mind, Hanabi had never once seen Natsu out of her kimono and apron uniform. The dark green-haired young woman was tall as ever, her white Byakugan eyes were as soft and kind as they always were, though Hanabi could tell that Natsu was quite exasperated at the situation she had gotten herself into. None of that mattered to her right now as she ran her eyes over her guardian's naked form.
The maid was as slender as the younger girl imagined, but not in such a way that she was devoid of curves. Her stomach bent inwards in a way that emphasized her cute belly button, her hips rounded outwards to form a shapely hourglass figure, and from the glimpse that she caught of it, her rear end was round and almost bubble-like as it jiggled slightly with her movements. Like all Hyuga women, Natsu's skin was fair and devoid of blemishes and hair, even in the spot between her legs, but even so, her slit was so small, it was almost invisible, which forced the younger girl to concentrate in order to pick up on her poofy lower lips.
Trailing her eyes upward, Hanabi froze her gaze when she caught sight of her caretaker's breasts. They were small, especially in comparison to Hinata's, but still very perky. And like Hinata's had previously been, Natsu's pink nipples were hard and erect, even though the air around them was as warm and humid as it always was. And just like with Hinata, Hanabi simply reached out and grabbed her caretaker's breasts. She couldn't help but wonder if their size would change how they felt and so she gave them an experimental squeeze.
Natsu gave a small jump when she felt a pair of hands suddenly cup and squeeze her breasts. The surprise quickly wore off however, though she made no move to stop her curious charge as she eagerly fondled and groped her bosom. Instead, Natsu focused on more important things, like drying off the youngest and possibly soon-to-be only heiress of the Hyuga clan. The heightening arousal certainly made her job far harder than needed, even more so than the distorted and slightly joggling orb of flesh that contained her charge's elder sibling. Natsu could only hope that Hinata-sama would soon see the pointlessness of her struggle and simply digest nicely for Hanabi-sama, though something told her that such a thing wouldn't be happening.
