Because the new generation of matriarchs possessed the blood of their ancestors, they were also given the mission that the ancestors had, which was to find a partner and reproduce.
But because they had weaker bloodlines compared to their ancestors, they didn't feel the urge to find someone to make some babies with, which was a sigh of relief to them, as no one normally wants to bear children just for the sake of it, at a very young age.
But they still felt the aftereffects of their insticts, and would have a more perverse nature compared to their peers, which was a nerfed version of their original desire to mate.
By saying they had a perverse nature, I didn't mean that they were horny all the time and wanted to satisfy themselves at every given moment, like a nymphomaniac.
And it was more along the lines of them, always craving something that could satisfy their desires. Even if they were having the happiest moment of their lives, they still wouldn't be able to be completely happy and satisfied, as if they were missing some part of themselves.
It was similar to having an itch that they couldn't scratch, or always looking for someone who didn't exist.
They would always be on the lookout for something that could truly satisfy them and make them feel whole, for the first time in their lives.
And the someone or something that could make them whole again, is unsurprisingly a man with a more powerful bloodline, as this desire of theirs stems from the matriarchs desire to mate with a man and bear his children.
In a generation, if there is a man who possesses a stronger bloodline, then the girls who also possess a stronger bloodline in that same generation, would naturally be guided towards that man due to their 'Resonance' ability.
And by using the 'Resonance' ability which could sync their minds after meeting each other, both of them would naturally understand that one party needed 'something' from the other, and the other party had the responsibility of providing it.
And the key point of all of this, was that by meeting a man with a stronger bloodline and being in a relationship with him to satisfy their own needs, they could lower the effects of their bloodline by using the stronger bloodline of the man to suppress their own.
Similar to how they could supress other people with weaker bloodlines than themselves with 'Bloodline Suppression', the man with the stronger bloodline can also supress his partner's bloodline, by satisfying his own desires and cravings.
But even though a human man with a more powerful bloodline, didn't have any side effects of having a stronger bloodline like the girls did, due to him possessing a bloodline more ancient and potent than theirs.
He didn't have the ability to simply control the girl's bloodline ability, like his own, and has to go through one out of three routes to suppress the girl's bloodline.
By doing so, they would be able to completely suppress the girl's side effects, which would save the girl from a world of loneliness and constant unsatisfaction.
It would essentially be the same as saving the poor girl's life.
Of course, if such a man didn't exist in that same generation, since humans with powerful bloodlines were more rare than demi-girls, then those poor girls could only be doomed to eternal loneliness and misery.
There are three ways in which the man can help suppress the woman's bloodline, which was also mentioned in the prologue.
The first was by being in a consensual relationship with one another. And having a child together, which would be more than enough to suppress the demi-girls abilities, since the girl would essentially be fulfilling her ancestor's mission.
The second is to have a relationship, where the man periodically satisfies her cravings.
Basically, the man gets to have sex with a girl, and the girl can suppress her urges, which is technically a win-win situation as long as both of them are down for it. But these meetups would have to go on for the rest of their lives, which was really inconvenient since they had lives of their own to live.
And finally, the third solution was using 'Absolute Dominance' on the girl, which was the most complicated method of the three.
It is essentially using the more powerful 'Bloodline Suppression' ability of a man, to completely dominate and suppress the demi-girl's bloodline and make it subservient to him.
It was similar to sealing the demi-girl's bloodline using the dominant aura as the lock, while the key to the lock was in the man's hand.
It may sound complicated. But it is essentially tricking the bloodline of the Demi-girl in her body, into thinking that its possessor was completely submissive to the man with a stronger bloodline, and held full control over her. And by holding complete control over its possessor, it was the same as holding over the abilities she possessed to the bloodline.
And the best way for one party to feel that they were completely dominant over another, was to let go of themselves and let all their desires they have, onto the other person without holding back in the slightest.
Only by knowing that the woman is willing to let go of all of her defenses, and is willing to do whatever it takes to satisfy the man's urges, will the man feel a sense of utter dominance over the other.
And in the case of the one who wants to be utterly dominated, they have to completely let down their defenses, and let themselves be dominated by the other.
No matter how degrading it may be, they must simply allow it to happen to themselves, to feel like they have truly submitted to someone else.
Once that dominant and submissive position is fixed between the two parties, the bloodlines lying within will act accordingly, in the sense that one will hold supreme authority over another, while the other is subservient to it.
It is simply using a state of one's mind, to completely trick the bloodline into following the orders of another bloodline, and completely sealing one's bloodline abilities and it's effects.
This method could only work between two people, who have somewhat similarly powerful bloodlines. And not by any people who didn't have any bloodline at all, since they wouldn't be able to trick the other party's bloodline, when the other person didn't have any bloodline at all.
The closest comparison I could give, would be a scale with two weights on each side.
When a man and women with bloodline traits in them are used as reference, the weight on one side will be a certain weight, while the weight on the other side is slightly heavier, but not enough to tip the scale; the heavier side being the man, because he has a more ancient bloodline.
Once the bloodline detects that its possessor is in a position of absolute submission, and the other side has complete control over its possessor, it acts along with its possessor and gets suppressed by the other bloodline, which in scale terms would mean that one weight loses some of its weight, allowing the other weight to cross the threshold and tip the scale.
When we're talking about a man with no bloodline and a girl with one, then there's basically no competition, as one side has the heaviest weight on the table, while the other weight is basically nonexistent.
I only say that this method is more complicated compared to others, when it seems easy because, one would have to know what they desire to do with the girl and how to properly execute it. Along with how to satisfy the girl, taking her feelings into consideration.
If the person simply forced the girl into doing certain things, in the name of making her submit, then it would only trigger her defence mechanism, which was what it was originally made for, and would make her fight for dominance.
It is essentially a two-person game, where one has to dominate the other person in such a way that they don't reject it. And the other has to completely trust the other person enough, to leave themselves to the other party, which I believe only a select few can do, as it requires one to be able to easily gain the trust of another and treat her in such a way that she feels loved. But at the same time, make her unable to not follow your orders, which was a difficult ordeal.
