In the morning next day, Leo woke up next to Anna's incapacitated body. The boy fell asleep last night on top of his sweet sister. Forgetting to pull out while they rested, the raging boner was inside the tight tunnel for the entire duration of the night until sunrise. Despite being in his sleep, the erection had never softened for a second until he unloaded a morning discharge shortly before waking up.
Startled by the sudden surge of volume within her stomach, Anna was forcibly awakened as well. If it wasn't for her large appetite in absorbing Anima, the voluminous cheese would have overflowed from her body in another entrance. The big sister bit down her lips, held back her moans and widened her eyes in shock to brace for the ongoing ejaculation.
"Leo... I am at my limit!" Anna pleaded.
"Oh, I am sorry." The boy just realized he was still inside of her.
Leo crudely pulled out his monster and unintentionally sent Anna into another heavenly climax. But as he tried to get off the bed, he was then immediately tackled back down by the big sister. Disregarding the surprise on the boy's face, she began to ferociously lick off the heavy stains of cum on the lengthy surface. Anna would not disgrace herself in failure to service the subject of her worship.
And thus, the morning session continued for a little while longer.
--------------------------
Before noon, the two arrived at the foot of the Halfmoon estate. The vast establishment was built around the waist of the mountain. There were many flights of stairs they had to climb before reaching the main gate, which was prohibited from the tourists to even remotely approach the area.
On the way up, Leo saw many totems placed along the path. Those stone statues and relics had been there for as long as he remembered since his childhood. Many of them were carved with mystical runes that looked familiar to the boy. However, they had been too eroded by time to be legible.
The size of the manor was beyond normal. It almost looked like a palace, with many courtyards and sections in-between each building. Yet, without enough people living inside, most of the interiors were run down and worn as they had been collecting dust. Anna explained that these used to be the living quarters for men who married into the family and the male servants.
"So, where are they now?" Leo curiously asked.
"They all died almost two decades ago." Anna nonchalantly answered, as if the death of all those non-blood related members did not concern her at all.
Observing the long maze of hallways, Leo had little memory of this place. Not that it would matter since he was also often lost within this expansive mansion during his childhood. Attentively following Anna as she patiently explained all the things that caught his interest, they arrived at a large wooden frame door within the halls.
In the midst of their conversation, Anna's expression suddenly turned solemn.
"Leo, we are here." Anna said as she kneeled down in front of the door.
"Eh?" Leo did not remember this part of etiquette.
"Please excuse me." The big sister gently slid open the heavy wooden door with ease.
There were two womanly figures in black robes waiting inside the room. They were also kneeling on the ground and facing towards them. The two ladies had the same beautiful charming face, the same voluptuous figures that seemed to run through genetic traits of the Halfmoon family, the same collar necklace on their necks, and the same long hairstyle that gently flowed all the way down to their rear bottoms.
"Ah, that accursed bible. I have not touched it for decades. Did you bring the book with you?"
"Yes." From a bag, Leo took out the heavy book wrapped in cloth.
"I noticed many contents within the later chapters are missing with blank pages. I wish to know the details about them." The boy earnestly asked.
"Impressive, child! You have already made it this far in your studies... Well then... I did not intend to be hasty, but perhaps revealing some secrets would help change your mind... Yuria, Filia, show it to him."
"Yes, madam." Yuria and Filia answered in unison.
To his surprise, the two well-endowed ladies stripped without hesitation, casually revealing their bare-naked bodies in front of the dumbfounded boy. The robes came down to the ground as if they were designed to be taken off at any moment, and no undergarments were worn underneath. Soon, an aura of Anima surrounded them as black inked runic letters with mystical faint glows appeared all over their skins.
"Young master, please come closer and look."
The twins boldly invited Leo to inspect the runes on their gorgeous bodies as they alluringly walked forward. These markings were like artistic tattoos that only enhanced their appeal. The boy was so astounded and perplexed that he didn't know where to look.
But of course, owing to his professionalism, the first thing he tried to*very attentively* figure out, was if the scripts were written left to right or right to left like when reading a manga.
"These were the runes scribed within the book long ago. Now, they have been ingrained into our bodies to ensure the spells are passed down through many generations." The twins answered the question in Leo's mind.
The knowledge of the grimoire was not comprehensible by most people even within the family. Hence, one of the ancestors developed a technique to strip the book of its runes and programmed the usage of the spells into one's body. But of course, the person who used the technique and built the program must first fully decipher the spell.
The mysterious powers of the runic script were wired like intricated circuits that can be activated without understanding their complexity. Ever since, certain knowledge within the grimoire had been passed down by transferring the runes into another body, and it had accumulated to an amount that it now required two vessels to hold them.
"Here, this is where it begins."
Yuria crouched down and spread open her legs with the help of her sister, and then pointed to the scripts starting at the base of her inner thighs. However, reading the runic letters will take incredible focus, her bare plump pudding right next to the runic letters was constantly distracting the boy from crucial work. Due to being too close, even the fragrance emanating from her flower would divert his attention.
Under the calm demeanor of the twins, Leo was then given a very detailed tour to every little crook and cranny part of their bodies. The underside of their bountiful breasts, the smooth skins inside of their armpits, the round surface of their hips and the tender soles of their feet, all were revealed to the fullest extent.
At one point, the sisters stacked their buttocks on top of each other, then mashed their breasts together, also locked their thighs across another and performed all kinds of lewd poses to match and piece the continuation of the script. The ancestor that developed the technique must have been very considerate when concerning the readability of these runes.
Before long, the boy felt heat converging through his crotch and his brain was getting dizzy. This was when he knew he should stop. It seemed like continuing to read the runes would take more concentration than ever before.
"Young master, you may seek us anytime shall you desire to indulge in further knowledge." The marking of runes faded from their skins as the twins dressed back into their robes.
