Yukito Mizuki stared fixedly at the prominent, towering peaks on Shiranui's chest beside him. Recalling the sweet "milk" Shiranui had prepared for him almost every night during his childhood, he couldn't help but swallow.
Ever since he accidentally discovered that the "milk" Shiranui prepared for him was freshly expressed, he hadn't drunk it anymore.
"Is Aunt Shiranui planning to prepare 'milk' for me like before? Actually, I don't think it's necessary to pour it into a cup. I wonder if I could drink it directly?"
Yukito's gaze lingered on Shiranui Mizuki's chest for a moment. A flicker of hesitation and anticipation flashed in his eyes as he tentatively asked.
"Not pouring it into a cup… but drinking it directly?"
At first, Shiranui was a bit confused by Yukito's words. Murmuring them softly to herself, she then noticed his gaze fixed on her chest and his eager, expectant eyes. A faint blush quickly spread across her fair cheeks, and her gaze toward Yukito became somewhat evasive.
She seemed to understand what Yukito meant, which left her feeling a bit flustered.
Although it was true that when Yukito was first taken in, she often prepared "milk" for him to supplement his nutrition, strengthen his body, and conveniently solve her own troubles,
later, after Yukito discovered that the "milk" specially prepared for him was freshly expressed, she stopped preparing it for him.
Even on the rare occasions when heightened desires, emotional excitement, or heavy consumption of Anti-Demon Factor caused her body to enter a lactation-like state, she would only choose to give that "milk" to her daughter Yukikaze to drink.
To this day, Yukikaze still doesn't know the true origin of this "milk," simply treating it as store-bought milk.
"Yukito… Not pouring it into a cup and drinking it directly… Isn't that a bit inappropriate?"
"Although Yukito-chan is indeed at an age where he'd be interested in girls, between us…"
Shiranui looked troubled. She cautiously glanced at Rinko and Yukikaze walking closely together and, seeing they weren't paying attention, lowered her voice as she spoke to Yukito.
"Well… this is only for this one time, okay? And you absolutely must not let Yukikaze and Rinko find out!"
Shiranui Mizuki had originally intended to refuse, but somehow, seeing Yukito's hopeful, expectant eyes, she ultimately couldn't bring herself to say no.
Gritting her teeth, a trace of barely perceptible shyness flashed deep in her eyes as she actually agreed to Yukito's request.
Apart from personally nursing her daughter during Yukikaze's first two years after birth, even when preparing freshly expressed "milk" for Yukito to supplement his nutrition, she always poured it into a cup beforehand.
Shiranui Mizuki had never allowed any man to be so intimate with her before.
"Huh?"
"Aunt Shiranui, you mean you agree? Not pouring the 'milk' into a cup but letting me drink it directly?"
Yukito said it casually, never expecting Aunt Shiranui to agree. Although their relationship had been close over the years and Aunt Shiranui doted on him, she likely didn't have any romantic feelings for him.
That she would be willing to let him do something so intimate was a complete and pleasant surprise, making him raise his voice involuntarily.
"Keep your voice down! Don't let Yukikaze and Rinko notice."
"This is only because your performance during the mission was quite good and helped resolve some trouble. It's a special reward for you."
"Besides drinking the 'milk,' you're not allowed to do anything else. After we get home and Yukikaze and Rinko are asleep, I'll find an opportunity to come to you. For now, behave yourself!"
Shiranui Mizuki glared at Yukito, warning him in a hushed tone, then quickly quickened her pace to distance herself from him.
She wasn't sure why she had agreed to such a thing. Even when, during a rare free period some time ago, she went to tidy Yukito's room and accidentally discovered several adult comics with "aunt" and "mother" themes under his bed—even seeing a heroine whose face and figure resembled hers—she had merely thought, "Yukito has grown up," without any further reaction.
But now, after agreeing to his request, she found her mind starting to wander.
"Mom, what were you just talking about with Onii-chan?"
"Why is your face so red? Were you injured in the earlier fight, or did you consume too much Anti-Demon Factor? But Mom didn't really do much, right? The demons we encountered in this mission were mostly handled by Onii-chan!"
Yukikaze and Akiyama Rinko walked side by side on the empty night street. Seeing her mother Shiranui catch up from behind with quickened steps and noticing her unusual expression, Yukikaze couldn't help but ask curiously.
"Yukikaze… I'm not injured. It's just been a long time since I fought demons, so the consumption was relatively high."
"Yukito-chan came to help us subjugate the demons in the Abandoned Hospital today without even eating dinner. I was thinking of finding a restaurant or izakaya still open nearby, but he wants to wait until we get home so I can prepare a late-night snack for him."
"Rinko, Yukikaze, are you two hungry? After we get home, I can prepare some late-night snacks for you as well."
Shiranui showed no trace of panic in front of Yukikaze and Rinko. A faint smile played on her lips as she casually explained.
Her words weren't exactly untrue. The reward she had promised Yukito and the late-night snack she was preparing to help fill his stomach weren't mutually exclusive.
It was just that the late-night snack she was going to prepare for Yukito was a bit special—the same "milk" Yukikaze had drunk as a child and still occasionally had the chance to drink.
"It's already this late. I'd rather not have any late-night snack to avoid gaining weight."
"Sigh… If gaining weight meant it would go to the right places, I'd be happy to put on a little weight!"
Having not overheard the conversation between Shiranui and Yukito earlier, Yukikaze didn't doubt her mother's explanation.
But just thinking about late-night snacks somehow made her think of her own underdeveloped figure. Her gaze subtly drifted to the ample curves on her mother and Sister Rinko's chests as she muttered with clear resentment.
Yukikaze couldn't understand why, as Shiranui Mizuki's biological daughter, she hadn't inherited even a trace of her mother's physical advantages.
She even wondered if she hadn't received sufficient nutrition as a child, or if she had a genetic deficiency that had caused her breasts to stop developing. There has been no progress for a long time
"Yukikaze… trying to make that area grow by gaining weight doesn't really work. You could try massage instead. Stimulating certain acupressure points might help promote development."
Shiranui glanced at Yukikaze's modest chest, her eyes briefly becoming complicated. After a short hesitation, she let out a soft chuckle and tried to comfort her.
Shiranui had never faced worries like Yukikaze's before. When she was Yukikaze's age, she already had the so-called "big D" figure, and her development showed no signs of slowing down as she grew older. During her two or three years in high school, there were noticeable changes every few months. After giving birth to Yukikaze, due to breastfeeding, her chest had even increased by two sizes. By now, Shiranui Mizuki had long surpassed that "big D" standard by several levels, and she honestly didn't know how to comfort her daughter.
Perhaps stimulating growth through massage would help, or maybe after giving birth in the future, there would naturally be some development.
"Yukikaze, you don't need to be too anxious about this kind of thing. You've only just turned sixteen, after all."
"Everyone's physique is different. Maybe you're just developing a bit later. You still have many years in high school, and even college—so there's really no need to rush."
Shiranui Mizuki gently patted Yukikaze's shoulder, offered a few more words of comfort, and then quietly returned to Yukito's side.
As for Akiyama Rinko, who was walking alongside Yukikaze, she could only offer an awkward smile and say nothing.
She didn't have Yukikaze's concerns, so naturally, she didn't know how to comfort her.
Yukikaze's frustration about her own figure made her subconsciously overlook the small secret between Yukito and Shiranui.
When the group returned to the Mizuki household, Yukikaze remembered her mother's suggestion that massaging acupoints might help her develop more. She immediately left the others, went to the bathroom to prepare for a shower, and planned to try massaging herself later in her room.
"Rinko, you're very familiar here, so you're not really a guest. Yukito-chan has always helped clean your room. I'm going to prepare a late-night snack for Yukito-chan, so I won't be entertaining you, okay?"
