Ezraphel hummed to herself as she took a relaxing soak. The house has two bathrooms and she was given exclusive access to one early on by her Stanley for personal use. She thought he was being considerate when he threatened to 'put a cap in her ass' if she snuck into his bathroom. At the time she just thought he had a preference for butt stuff and his 'threat' was secretly an invitation so of course snuck in while he was preparing to bathe.
Unfortunately it was at a time when he still kept those accursed 'air rifles' with him at all times and well, Stanley did end up doing stuff to her rear but it wasn't at all fun and soreness afterwards was not very pleasurable. From that lesson Ezraphel learned the value of looking up unfamiliar slang terms whenever they came up, it saved her a lot of potential setbacks in advancing their relationship and Ezraphel would say that it was worth it
'Ah, that was a nice change of pace, getting dirty then clean and back again simultaneously.'
Of course with the frequent servicing of Stanley's manly member Ezraphel has been able cultivate her demonic energy much quicker and thus enabling her to perform what Stanley called 'frivolous spells.' He calls it frivolous but Ezraphel would beg to differ, for instance with a bit of minor space-time magic she was able to turn what was once an adequate Earth-standard bathroom into an indoor bathhouse, something she was more familiar with and to her standards.
Stanley's response?
"You better be using magic to refill that thing cause I'm not paying the water bill for that crap."
Ezraphel's response?
Two minutes later and Stanley was sitting naked by the edge of the pool bath receiving a most excellent titty fuck from a half submerged Lilim.
Ezraphel sighed at the memory 'we should do that again, tonight perhaps?'
"Hmm~" she purred at the thought, getting excited all over again and the fact that she could still taste Stanley in her mouth only intensified the feeling. Finally she managed to reign herself in "not yet, Stanley still needs time to recover."
Of course if he were an incubus then you would still be sucking, drinking and even fu-
Ezraphel silenced those thoughts as she took up a 'mesh loofah' and began to clean herself languidly.
'I made it this far without slipping into those habits. I can survive for a little while longer'
Emphasis on the little
Now that Ezraphel has tasted the life essence of her beloved she has already become addicted to it and that addiction is going to become a problem sooner or later. Considering that she was getting hot and bothered from the mere thought of tasting her Stanley's cum, it was going to be a problem sooner than later.
It wouldn't have been too much of a problem if she could incubize her Stanley but even if he wasn't against the idea Ezraphel doesn't have the capacity to that. It came as a shock to her that for as much as she is milking Stanley for everything he's worth she wasn't receiving early as much mana as she thought she would. Compared to Eos earth is like a barren wasteland when it comes to mana and she took for granted the mana friendly environment of Eos. Her home world is so saturated with mana that she could recover her reserves without the aid of consuming spirit energy.
Here her only source is spirit energy, specifically Stanley and both the quality and quantity of what she receives depends on his strength and vitality. Unfortunately her Stanley is below average both these aspects and it would take months of conditioning before that could change. Luckily in the time since her arrival on earth Ezraphel has wizened up and is not the same Lilim she was before.
Proper management was the name of the game now with Ezraphel becoming more self aware about her use of mana. Frugality and the benefits of being economic was something she learned from her Stanley. On Eos it was considered the norm for those with wealth to show it in the most grandiose of fashion but the same could not be said here. Stanley is a man with wealth but he does not go out of his way to show it.
Why bother?
It would gain him nothing but unnecessary attention which is par for the course with his personality but he is far from the only one. Wealthier men and women also follow such a philosophy though it has more to do with security but many just lack the vanity which is not a bad thing.
So where does Ezraphel apply her own brand of economy?
Whereas before she would have a number of spells and enchantments active they were in fact practically redundant. Now without them there was a stark contrast as she found the layers of superfluous spells had taxed her reserves more than she imagined. Ezraphel is much stronger than she gave herself credit for, at least that's what she came up with once she began to properly cultivate her reserves without directing power to a superfluous spell or enchantment.
Even more, now that she was conscious of her internal mana it became clear to her when casting spells that she has the habit of pouring more mana than necessary when casting. It was a resultant habit of having too much and being able to afford the loss. Not anymore and the resulting halt to that bad habit has resulted in a more efficient usage when doing spells.
Now that she was at the height of awareness of her own mana Ezraphel came to the startling conclusion that she might not be able to Incubize her Stanley even if he allowed it. Monsterization works through corruption which is the bestowal of large amounts of demonic energy in a person. Due to the nature of Mamono monsterization had become the preferred method of winning battles. A lot of resources have gone into researching monsterization and corruption as a whole resulting in a few noteworthy breakthroughs.
One such breakthrough is the 'environmental factor' which led to the discovery of a more efficient method of monsterization. Mamono of vast power like the Lilim could just inject their own mana into a human to achieve monsterization however a more efficient use would be to corrupt the mana around them and let their body absorb that infected mana naturally. This way takes more time and concentration but it is less taxing on the reserves. It was a personal triumph for her that she figured this out, or rather that she remembered the teachings on the subject.
A personal triumph but one that ultimately held no meaning in this instance for Ezraphel wouldn't be able to do either method in her current state. The realization came as a shock to her after so much rumination but it's the truth. The simple fact of the matter is that corruption in and of itself is neither simple nor easy, she and her family just makes it look easy. There is a reason why not all Mamono can corrupt individuals in the same manner as a Lilim and it's because it involves direct mana manipulation.
It was difficult enough to pull off on Eos but on the mana barren earth and with her reserves nowhere near full, it was easier for her to alter the size of the bathroom than to directly corrupt him at this point. The reason being that altering the bathroom size is a spell and it was through this that she found something peculiar about the world. Earth may be barren of mana but at the same time it is shockingly receptive to magic spells, so much so that her lack of mana is compensated by the ease of casting the spell.
It is easier to cast magic spells in a place devoid of mana. It was a paradox and a question reserved for the scholars. What Ezraphel gained from this however is that she can cast high level spells with more ease provided that she has enough mana for it. This works out perfectly for her because now she has a way to get what she wants without violating her Stanley's order.
Her Stanley wouldn't be the first man to want to hold onto his humanity and there are enchantments created to protect against demonic energy. There is even a spell that not only protects against corruption but preserves the humanity of the human it is cast upon. Naturally such a spell is of the highest rank and only Mamono of exceptional power can cast it which is why it is a popular spell used mostly by the Royal Makai nobility.
Unlike other places where Mamono would often compete over the number of men they slept with or conquered, in the Royal Makai the Mamono are so powerful that such things hardly matter. In a place with the highest concentration of Lilim and mamono comparable to them in power, prestige and charms what would be the point of bragging about sex?
Rather than power or the number of sexual conquests what the Makai nobility value is cunning. If you can demonstrate a high level of cunning when obtaining a husband then you will earn respect amongst the nobles. If at the end of the day you had to use your vast powers to 'cheat' and secure a win, the best stories are always of Mamono who are caught at a disadvantage and manage to use their wits to secure a victory.
It is actually due to growing up with this kind of culture in the Makai courts that Ezraphel is became less inclined to force herself on Stanley. To the average mamono it might be an inconsequential thing, the ends justify the means after all but not when it comes to pride. Plus there is the added effect of perception, people wouldn't say anything even if she were to force herself on him but they would think less of her.
She was specifically referring to her family and how some of them hold the perceived 'purity' of a union in high regard. A human needs to accept a Lilim without the need for such things as sex or magic. Put simply, this is love in its purest form and there is something oh so tantalizing about it.
In this case it is for this reason why the story of Lilith and her husband, Ezraphel's father, Adam is so so popular. It wasn't that he fell to her charm magic or was even influenced by demonic energy corruption. He gave up his belief in the Chief God, took a leap of faith by trusting her and eventually accepted her feelings for him. Theirs was a relationship built solely and mutual affection, love in its purest form.
As for the spell itself Ezraphel's mother acknowledged its worth and mandated that all her daughters would learn it as a means of further proving her family's willingness to cooperate with humans should the opportunity arise. With that announcement the other noble houses in the Makai followed suite and the 'Human Preservation Ritual' was taught to all future generations.
Ezraphel was no different and was taught by her mother to cast it but there is a problem. It wasn't the lack of power, she will eventually have enough after feasting on her Stanley's sprit energy. The thing is…about the spell…Ezraphel may have…sort of…forgotten…how to cast it.
Yeah…
Recently when she wasn't servicing Stanley she was wracking her brain trying to piece together the proper procedure with which to cast it. Such an oversight could only be attributed to the folly of youth on her part. Specifically when her mother was teaching her the spell Ezraphel's thought process at the time went along the lines of being unable to fathom a reason or want for preserving someone's humanity, let alone her husband. Humans were inferior to Incubi in just about everything that mattered and the Ezraphel of the past could not think of a situation where she would cast such a needless spell.
…if she could, Ezraphel would travel back in time and 'bitch slap' herself.
Ezraphel could now only try to salvage her memories for the spell whilst cultivating as much mana as possible. Fortunately Ezraphel was well versed in the art of Spell Crafting and with what she remembered of the Human Preservation Spell she might be able to create something close enough.
'Better yet I will be able to create a spell far superior!' she raised a long leg daintily and ran the loofah down in strokes 'and after the spell is complete…' she grinned 'ooh, I'm getting excited all over again' a frown came across her plump lips 'and no Stanley to be had.'
It was a prevalent problem nowadays, however in times such as these she had a backup plan. Reaching out with her magic she levitated the detachable showerhead, a quaint little invention that had done wonders in assisting with her luxurious hair back when she was powerless.
"Eh, it will have to do" she shrugged.
Ezraphel leaned back in the pool, turned the showerhead settings to 'Power Massage' and dipped it between her legs.
"O-oh yeeesssss~"
That's the good stuff.
