William woke up with his new mass manipulation magic fresh on his mind, and naturally, he wanted to test it out first thing in the morning.
It was still quite early. Serena and the other lamia girls were busy planning their route for the day, and he'd been thinking about how to spend this free time anyway.
This seemed like the perfect opportunity to experiment.
"Let's try a full body reduction first."
Without needing to chant or recite any spell incantations, William directly activated the magic within his body, channeling it through his form as he performed the magic spell with nothing more than focused intent.
After completing the reduction process, William successfully transformed from his usual powerful demon king form, standing at three and a half meters tall with imposing wings spread wide, into a significantly smaller version of himself, now only about one meter in height with proportionally reduced wings and horns.
William had specifically calibrated this particular body size to be practical for everyday activities and movement.
He could theoretically shrink even smaller if the situation required it, but he figured he'd reserve those extreme reductions for reconnaissance missions and other specialized purposes where being tiny would actually matter.
William's sudden transformation naturally startled the fox girls who had been sleeping peacefully beside him in the bed.
Among them, Arisu was the first to wake from her slumber. She quickly rubbed at her somewhat confused and sleepy eyes, then immediately turned her gaze toward William's position.
What greeted her sight was the dramatically shrunken William.
"M-Master William, what on earth happened to you? You've suddenly become so incredibly small! Could you have been cursed by some guardian from another tribe? Wait right there, I need to call the Tribe Elder immediately!"
Arisu's tone carried genuine worry and concern. William's current appearance was truly extraordinary and unusual, making it difficult not to immediately associate it with some kind of malicious curse or hex.
"Easy there, calm down, Arisu. I'm not affected by any curse whatsoever. I changed myself on purpose this time around. I suddenly acquired mass manipulation magic when I woke up this morning, so naturally, I wanted to try it out and see what it could do. This is simply the result of that experiment."
Hearing this explanation, Arisu was momentarily stunned, her fox ears giving a confused little twitch as her expression shifted to something incredibly cute and endearing. "Huh? Is that really true?"
"Yes, completely true." William gave her a slight nod of confirmation.
After seeing William's reassurance and confirmation, Arisu visibly relaxed and let out a breath of relief. A warm smile bloomed across her beautiful face once again, and her fluffy fox tail resumed its happy swaying motion behind her.
"I'm so glad that Master William is perfectly fine. By the way, since it's already morning now, Arisu's Holy Water for Master William is all prepared and ready." As she spoke these words, she pushed her chest forward in a presenting gesture.
She simply reached behind her back to undo the binding strap, releasing the large mass that had been restrained and held in place.
Whether it was truly ready as Arisu claimed or not, when the strap was finally released, you could vaguely see that the Holy Water seemed to already be flowing out, dripping down onto her pristine white skin in thin rivulets.
Looking at those large, liquid-soaked breasts presented before him, William found himself unconsciously swallowing hard.
He had just woken up in the early morning and hadn't eaten anything yet, which meant he was definitely quite hungry by now. Fortunately, Arisu and the other girls had more than enough calories and nutrition to feed him the equivalent of several full plates of meat.
Without bothering to say another word, William directly pushed Arisu down onto the bed beneath him. His demon king features, the dark scales covering his body, the small horns protruding from his head, and his sharp fangs might look fearsome and threatening to outside observers, but to Arisu they were nothing except endearing and adorable as he took her Holy Water into his mouth and began drinking.
At the same time, William reached out with both of his hands to touch and caress her. His demon king claws were considerably smaller now after the shrinking transformation, and while they were still tipped with dangerously sharp points, they had become far more delicate and precise in their movements. This newfound delicacy allowed him to have a much more refined and gentle touch than before.
Previously, when he had been so enormously large, William hadn't dared to grasp the women's breasts directly with his clawed hands.
He'd been far too afraid that his razor-sharp claws might accidentally hurt them or cause injury.
Now, with the mass manipulation technique reducing his size, there were considerably fewer concerns and worries about such accidents.
"My mass manipulation magic spell is quite interesting when you think about it. This isn't just some conceptual or abstract reduction of size... It actually feels much more like genuine physiological regression to me. All of my physical features have become more similar to what you'd expect from a young, adolescent demon king form." Looking down at his palms, which now had much better proportions relative to his body, William's eyes sparkled with the light of realization and understanding.
"Ah~"
And Arisu, who had been pushed down onto the bed by William, now had her eyes going hazy and unfocused as she stared at him, continuing to suck and drink the Holy Water from her breasts. Her delicate body trembled slightly with sensation, and her lips parted as her breathing became noticeably faster and more labored. Her soft fox tail instinctively curled around William's smaller frame, wrapping him in its embrace.
She reached out with gentle hands and softly hugged William's head closer to her chest, a deeply maternal smile blooming from the corner of her mouth.
To produce truly high-quality Holy Water, the single most important factor was having a genuinely loving mother's heart, and the purer and more sincere that maternal feeling was, the better the overall quality of the Holy Water that would be produced.
At this particular moment, Alice, who had still been lying and sleeping slightly to the side of them, was finally awakened by all the movement and activity the two of them were making.
She staggered upright and rubbed at her sleepy eyes, her fox ears drooping noticeably with drowsiness as she pouted with clear dissatisfaction and complained in a low, grumbling voice. "Ugh... Sister, Master William, even though I can totally understand the intimate feelings between you two, doing pleasurable things like this right next to your little sister first thing in the morning and making such a noisy commotion about it, no matter how you try to justify it..."
Before that last word could even be fully spoken, Alice's complaint suddenly stuck in her throat and cut off abruptly.
Because she had also just now discovered and noticed that William looked completely different from his usual appearance.
"Whoa! Master William, why have you suddenly become so much smaller? Is it because you've suffered from some terrible curse? I need to rush out right now and tell the Tribe Elder about this... Sister, why are you just lying there smiling so happily when Master William has become like this!"
Her fluffy fox tail immediately puffed up in alarm and concern.
Watching the clearly anxious and worried Alice, William glanced over at Arisu beside him once more and couldn't quite hold back an amused breath of laughter. As expected from a pair of sisters.
Even their words and reactions were basically identical to each other.
But this time it wasn't William who opened his mouth to explain, but rather Arisu who spoke up to explain the situation to her younger sister.
After hearing all the reasons and the full explanation, after learning that William currently looked like this because of some new magic ability he had acquired and learned this very morning, Alice's eyes gradually filled with sparkling curiosity rather than concern. Her fox ears perked forward with obvious interest and excitement.
She lay herself down directly in front of William, her appealingly curvy and charming figure displayed openly before William's eyes, her fox tail swaying in a playful manner as she asked with genuine curiosity, "Master William, can your mass manipulation magic shrink you down even smaller than this? For example, like you were when you were first born? That version of Master William was so adorable, but now that I think back on it, I really miss seeing you like that. The problem was that you changed and grew the very next day before I could see nearly enough of you in that form."
Speaking about this missed opportunity, Alice's expression became filled with visible regret, her fox ears drooping sadly at the memory.
Hearing Alice's suggestion and proposal, Arisu, who was currently in the process of feeding William her Holy Water, also visibly brightened, her beautiful eyes lighting up with interest. For her specifically, William's appearance during the time when he was first born held special significance as it was the key moment that had connected them.
If it hadn't been for her presence and help at the very beginning, she wouldn't have the ability to produce such high-quality Holy Water for William now in the present.
When William heard this request, he paused briefly in his feeding, thinking it over for a moment, and then decided to perform the mass manipulation magic once again. He was genuinely curious to see just how much he could actually shrink down using this magic technique and what its limits might be.
After executing the mass manipulation magic for the second time, William's body shrank down even further than before, but this time the absolute limit of the reduced state stopped precisely at William's newborn appearance and size. His demon king features became adorably miniature and tiny, little horns that were barely even visible, small wings folded neatly against his back, making him look exactly like a newborn demon king hatchling fresh from the egg.
If he attempted to shrink himself any further beyond this point, nothing would happen. This seemed to be the absolute minimum with his current power.
And upon seeing that William had successfully transformed into exactly what he had looked like when he was first born, both Arisu and Alice's eyes began sparkling with pure delight and joy.
When it came to adorable things, neither women nor girls seemed capable of mounting any resistance whatsoever.
"So cute and incredibly soft to the touch!" Alice seemed completely addicted to touching and petting him, her behavior gradually escalating from using just one hand at the beginning to employing both of her hands enthusiastically. Her fox tail wagged with intense enthusiasm and happiness.
William simply lay there lazily and contentedly on Arisu's soft chest, completely ignoring Alice's somewhat rough handling and petting behavior, and he continued drinking the Holy Water without pause or concern.
At precisely this moment, Marigold entered the room with purpose, intending to deliver her daily morning report, which was one of the regular tasks that William had specifically assigned to her.
But the very instant she stepped through the doorway, Marigold's eyes fell upon the sight of William lying peacefully on Arisu's chest in his newborn demon king form, and both her eyes and the words she had been about to speak froze completely for a long moment.
"So, so cute... Master William!" At this moment, it was as if flowers were blooming throughout Marigold's mind, and her pupils became completely filled with overwhelming love and adoration.
Faced with the new form of William, Marigold found herself having absolutely no resistance whatsoever to his shota form.
