The Demon purred happily and licked her lips as the Mana entered her stomach, then frowned as she began to absorb it.
"It's not enough to break through." She muttered.
Wolfe smirked. That much was already obvious. If it was so easy to break the restrictions between levels, all Demons would advance at least once in their lives, and the witches who summoned them would be screwed.
Possibly literally.
Wolfe pulled her to the bed and set the Kitsune in his lap, then thrust up into her as he poured Mana into her system to overload the restriction and flood all her cells with denser mana than they could currently handle.
Wolfe could sense the amusement of Cassie and Ella, who had only gone down the hall to visit Mia and some of the other Witches, as the Demon's moan turned to a wail as the effect of the mana hit her with full force.
Wolfe felt the claws dig into his shoulders as the Demon came undone, but he didn't slow his pace, and he continued to empty his Mana Storage as her cells flooded with energy and began to change.
"Don't stop. Please don't stop." She begged as the Mana Surge peaked and then collapsed into Wolfe's arms as both Wolfe and the process finished inside her at the same time.
Wolfe leaned back as her tails sporadically twitched and took the opportunity to stroke them while they were in reach. Mary had a point about the fluffy tails. The softness was top-notch, and the silky feeling against his skin was incredible.
She began to wriggle as she woke up, and Wolfe was instantly hard inside her again, bringing a smile to the Demon's face.
"Just one more time to solidify the upgrade." She purred, reminding him more of a cat than a Fox.
Wolfe wasn't going to object, though, and picked up the pace to match her eager motions.
"Don't forget to absorb what you can. The witches use it for their aura, but I'm sure you can use it to energize your cells and stabilize the change." He whispered.
"That shouldn't be bedroom talk, but today I will let it pass." She replied, but the look on her face said that he could have told her anything, and she would have accepted it at this point.
This time when they finished, Wolfe felt something shift inside him, and a new bond was formed.
[New Servant Gained] Kira
The Kitsune was out cold, so Wolfe just waited and held her while she slept. Cassie and Ella stuck their heads in after a few minutes and smirked at him.
"So, you broke your new toy, did you? I felt her advancement, though, so you did manage the actual purpose behind doing lewd things with the Fox Demon." Cassie said softly.
"Oh, my Goddess. Look, she is growing another tail." Ella whispered, pointing to the spot where a third fluffy mass was joining the other two.
"That is too awesome. So, you can tell what Rank a Fox Demon is at by their tails. Be sure to congratulate her for us when she wakes up. We're going to the gardens. It's been decided that we will make enough to keep everyone supplied, even though there is more food available in the Forest than there was in the Wastes, so Cook wants ten times as much garden as we had." Cassie explained.
"Don't forget some sort of support beams. That's going to be a huge cave." Wolfe agreed.
"The plan is to make it a series of smaller caves, about the same as the one that we have now, separated by the sorts of things that grow in them so that we can tailor the climate in each of them for better growth rates with less magic usage.
With so many Rank Two witches, it's going to be an easy task. Now we need to teach you cool Magi tricks so that you can show off the powers of a real Magi, other than keeping a harem of Witches fed with Mana." Ella told him with a wink.
"I will have plenty again in a few minutes. It took two Mana Focus worth of Mana to help her advance." Wolfe replied.
Cassie and Ella both stared at the unconscious Demon. No wonder she was unconscious. That was way beyond what would have overloaded either of them. It might have even been enough to overload them both at once, and they could handle quite a bit of power now.
Kira woke up after half an hour to find herself in Wolfe's arms and all cleaned up with magic. Even the sheets that she was lying on had obviously been cleaned while she slept.
That was the first time she really observed the room and realized that it was all magic. Every bit of what she could see was an inscription, and there was a cleaning spell engraved into the wall, under the false appearance, so Wolfe could remove all dirt and move items back to their proper place in an instant.
"This place is almost as incredible as the village above us. To think that you have learned so much already." She muttered, not realizing that Wolfe was awake behind her.
"I activated a part of the Inheritance Spell. But it's mostly only the basics, according to the ancients. That's why I need things like that book on weapon creation to get a fully rounded set of knowledge." He explained.
"That's still a lot. Do you think that we can take a tour of this place while I wait for news about my cousin?"
"I don't see why not. After you, Miss Kira."
The Kitsune got to her feet with shaky legs, and Wolfe did his best to hide a smirk. She took a minute to get herself steadied and properly dressed by activating an amulet to create a comfortable-looking blue dress and putting her cloak back over her shoulder, but open this time to account for the heat.
"Let's start with the dining room, I'm sure you're hungry, and they should have lunch ready to be served."
