Feeling the emptiness that follows masturbation, she licked the love juices from her fingers, asking the question to no one in particular.
The next morning…
Though it was already past noon, Rias and the others came downstairs. Their skin was glowing, and their beauty and sensuality had increased even further.
Then, during dinner that evening, Artoria, and the next morning, unbelievably, even Venelana, had become similarly more beautiful.
Unable to overlook this any longer, after seeing Rias and the others off, Grayfia confronted the Lady.
"What exactly are you thinking, ma'am!?"
"What do you mean, what?"
Her skin glowing, even more beautiful than the day before, the Lady showed no sign of being flustered as she asked back.
"My Lady... where were you last night?"
When Grayfia asked, Venelana gave a bewitchingly beautiful smile.
"You know, don't you? In Kazuki's room. Ah, and of course we had sex."
She stated it as if it were the most natural thing in the world.
"Ma'am... what are you thinking!? Kazuki is Rias's fiancé, he's going to become your son-in-law!? Sleeping with someone like that... it would become a scandal for the Gremory family!"
"Oh my, do you really think so?"
In contrast to Grayfia's emotional outburst, Venelana remained perfectly calm. As she wondered about this suspiciously, the Gremory MILF began to explain with an expression of complete composure.
"You know about it too, don't you? That among the old aristocratic systems, there is something called the 'Temporary Education System.'"
"That is..."
She had indeed heard of it. However, in this case, 'education' referred to sexual education.
The most important thing for nobles was to produce offspring. Yet, the birth rate among devils is low. To compensate for this low rate, a system was established after the Great War when the population had plummeted. Experienced noblewomen would provide 'education' – in essence, act as sexual partners – to men of marriageable age to stimulate their interest in procreation.
But now, it's a system that has become a mere formality; there are almost no nobles who actually make use of it.
"That's right. But even a system that's become a mere formality is more than enough as an excuse for me to sleep with Kazuki."
"---!!"
Grayfia never imagined such a loophole existed... She had to admit the Lady's skill was impressive, cleverly utilizing an old, outdated system to fulfill her own devilish desires.
Venelana turned an amused gaze toward Grayfia, who was taken aback.
"Besides, with this system... I'm not necessarily the only one who can serve as the partner. Isn't that right, Grayfia?"
"!!?"
Grayfia's heart leaped. 'Could it be that Madam... is trying to give me an excuse to sleep with Kazuki too?'
With a bewitchingly beautiful smile, the Gremory MILF whispered in the MILF maid's ear.
"Grayfia, I understand perfectly well what state you're in. Because until yesterday, I was the same. For women like us, who have been sexually suppressed, sex with Kazuki is like a drug. Once you're hooked, you can't break free."
The words of the Lady, no, her mother-in-law, seeped into Grayfia's heart.
Mother-in-law had suffered from unfulfilled sexual desires because her partner was sexually indifferent, while she, due to her frigidity, had never understood the pleasure of sex.
Was it fortunate or unfortunate that a man like Kazuki appeared before them?
Either way, Grayfia was forced to choose. To refuse her mother-in-law's invitation and stay true to her feelings for her husband, or to accept her mother-in-law's invitation and drown in carnal desires...
...The answer was already decided.
That afternoon, as soon as school ended, Rias and the others arrived.
They were disappointed to learn that Asia was still sleeping, but accepting it as unavoidable, they each spent their time in their own ways.
Among them, some visited Asia, some trained diligently, and some relaxed. Kazuki was with Rias, compiling an incident report.
Whenever an incident occurs and the family is involved, the King must compile a detailed report of the incident and submit it to the Satans. Rias, of course, and now Kazuki, as a newly risen noble and new King, have the obligation to submit such reports.
Beside them, as Queens, Akeno and Artoria were helping, but while Rias and the others were managing, Kazuki and Artoria were struggling with the unfamiliar paperwork.
Grayfia had accompanied them to the library to assist Kazuki and the others.
"Rias, this is the last one."
"Thank you, Akeno... Yes. Good, we're finished. Grayfia, please submit this to Onii-sama."
Rias and the others finished their work first, as expected. Grayfia received the documents and praised them.
"Understood. Good work, young lady."
"Kazuki... still looks like he'll take a while, huh?"
Kazuki and Artoria were holding their heads in their hands while looking through documents.
"Kazuki... I can't go on anymore."
"Don't whine, Artoria. You were a king yourself, weren't you? You must have experience with paperwork."
"Ugh, my steward, Sir Bedivere, was so capable that all I had to do was give my approval..."
"Honestly..."
Rias watched their exchange with a mix of exasperation and amusement, then let out a sigh.
"It can't be helped. Let me see it, Kazuki. I'll help you."
Kazuki and Artoria's faces lit up with joy at Rias's offer. But Grayfia intervened.
"Please wait, young lady. Kazuki is now a King who has his own peerage. For his future sake, please refrain from interfering."
"You're right... that is true."
"Please leave Kazuki and the others to me. I will teach them strictly and make sure they can at least write a report properly."
The joyful expressions on Kazuki and Artoria's faces instantly turned to despair.
"That's right... Kazuki, Artoria. This is also a test. Do your best!"
"We have other things we need to do, so we'll be excusing ourselves."
Rias and Akeno offered words of sympathy before leaving the library, leaving the three of them alone.
"Now then, let's resume the work. Don't worry, with my guidance, the report will be finished in no time. It might be a little strict, but please do your best, both of you."
"...We're... in your care..."
