Milking 

Returning from the family headquarter, which unsurprisingly became his personal brothel, the boy shut the door behind his room and let out a sigh. Even after dumping his load into numerous family servants, to the point their wombs were filled like condoms, he wasn't able to expel enough energy for the twins to re-strengthen the seal.

Instead, while their bodies were trembling in spasm, Yuria and Filia could only pour more of their Anima into the newly installed cock ring to help temporarily suppress the swelling energies. Between Maria's and Komi's excessive feedings that spurred the fusion reaction of the arch demon's power, Leo was growing in strength at a pace faster than the family's calculation.

The landlady and the head priestess almost couldn't keep their businesses running with most of their staff wasted in a puddle of cum.

Once his engine was ignited after merely a few days of holding back, it wasn't going to stop with just a few dozen condoms filled to the brim. At the end, despite being at her limit, the mother had to join the fray herself to stop his libido from further rampage, which was the reason why Leo returned to the apartment alone.

After taking a hot shower, the boy took out the grimoire that he had been neglecting. The solution to his current problem was surely hidden within its mysteries. However, before he even had time to flip the first page, he was interrupted by a timely visitor at the door.

The guest was Yurin, the cult member working as a doctor in the town's hospital.

"Ah... I almost forgot that you were coming. Where is your daughter?"

By the entrance, Leo carefully looked around and held a defensive position to brace for the usual bone crushing hug. Komi had been regularly visiting at this hour for her meals; but unexpectedly, the woman was not with her daughter this time around.

"Komi is err... in a strange condition. It is difficult for me to explain, but I am going to need a favor from you." The woman was behaving quite odd, a rare agitated and awkward look was on her face.

--------------------------

-A few minutes later-

"Are you sure that you are going to do this?" Seeing her trembling hands, Leo asked in consideration.

"Yes, Komi is in hibernation, but she is still demanding your seeds. I must do this as her mother!" Yurin said with a determined expression.

"I can go see her instead, you know."

"No, they actually increased the security there. You won't be able to sneak inside without triggering their traps."

Currently, soaring majestically before her eyes, was the erected tower of the great beast bulging mightily with an aura of dominance. Runic patterns originating from the silver ring were extending outward and glowing on the veiny surface of the immense girth.

The artifact was activating at full strength to prevent the rod from swelling any further. Yurin was basking in awe no matter how many times she witnessed this monstrosity.

As the big girl was not in any state to forage the food for herself, the mother took it upon her responsibility to milk out the much-needed nutritious proteins for her daughter. Komi had never been a needy child even before she was sacrificed; it was the first time the girl pleaded to her mother with an ingenuous request.

"I-I am going to start... Can I put this on?" With a piece of XXXL magnum condom in her shaking hands, the woman matched the size of the rubber with the enormous bulging gland.

"Uhm... my girlfriend used to do this too, but she stopped using them when they start popping whenever I let out too much... you might want to use that instead."

Leo embarrassingly suggested and pointed to a bucket that a certain succubus left in his apartment. Lilith had always procured food for her family, and loading them in condoms was no longer practical. The succubi mother was quite a glutton as well; their whole family was relying on the boy to provide the meals on the table.

"..."

"That might actually be a better idea..." Yurin wryly commented after a moment of silence; considering her daughter's appetite, she probably will have to make a couple round trips even with the bucket.

Now, with the large durable container placed on the floor, Yurin finally laid her hands on the innocent young boy. The second her fingers came in contact with the rough surface of his manhood, she felt its scorching heat burning through her skin.

A massive amount of energy was congested beneath the runes, waiting to be released at any moment notice.

Yet, amusingly, while her eyes were staring at the mushroom cap, the orifice suddenly widened and a thick stream of cheese abruptly gushed out, dyeing her face in white. The boy had been unsatisfied from the brooding earlier during the day; his manhood was still ultra-sensitive to any stimulation. A slight touch from her tender womanly hand was all it needed for the pre-cum to start spurting.

----------------------

The time quickly fast forwarded to evening after many hours of endeavor. With a bucket full of densely condensed substance in her hand, a certain lady in white lab coat returned to her private laboratory at the hospital with clear signs of fatigue.

Despite her enhanced strength as an Anima user, carrying the heavily loaded container for many trips still took a toll on her body. Her hands were also bruised in red from the intense heavy strokes on that hardened surface of the boy's veiny iron rod.

Every explosive load was held firmly in her arms, the powerful ejaculations were shot into the bucket like a garden hose on loose; the woman was still feeling its trembling impact reverberating throughout her entire body.

However, all of her hard work had been well worth it. Her daughter was extremely delighted after the meal and asked the mother to have the rest for herself. Similar to the link with Leo, Komi was also able to communicate simple thoughts with her mother.

With enough nutrients in place, the big girl could now safely continue her evolution.

"I need to know... just how in the world is that boy able to produce an endless amount of Anima."

Yurin scoop out a viscous sample from the bucket and attempt to examine its mysterious properties with various high-tech equipment in the lab.

Under the microscope, her first discovery was the overly inhuman size of his sperms compared to a normal male. And not with just the scale of the mass, their vitality was abnormal too; being able to stay active under extreme environmental conditions.

She soon noticed that the sperms were artificially enhanced due to the dense concentration of Anima inflating their size. With an experiment that drained the energies away, the volume of samples did become smaller. Yet, appallingly, the sperms remained at least five times larger than normal, and were still wiggling energetically under the microscope as they slowly recharged their power.

Perhaps this simply indicated the natural fertility the boy possessed, but the problem with being excessively fertile, was that his sperm was simply too large to fertilize female ovum. The discovery explained the ridiculous volume in his every ejaculation, as well as why none of his harem were ever pregnant.

Yurin still remembered the runic patterns scripted on his manhood. From its design, the woman could easily deduce the cock ring's function with her experience. She couldn't imagine the thickness and density her current samples would have been if that limiter was removed.

At the corner of her memories, there were faint cracking sounds from the silver ring in the midst of Leo's thunderous discharge.

-----------------------------

After further experimentations, Yurin arrived at an eldritch truth that overrode all her belief of the great abyss. Terrible demons born from the bottom of hell, divine beings that wielded immense power unimaginable to mankind, they all seemed miniscule before the boy's limitless potential.

The woman finally understood why her daughter, despite transcending into a godly entity, chose Leo to be her master.

From the clues she managed to pick up with just his sperms, they carried the purest essence of life energy in its most primordial form, even more pristine than the Anima of the abyss. The more refined it is, the more possibilities exist. The essence of divinity that the cult had always been searching for was already before her very eyes.

Learning such of truth, flames of desire appeared in the pupil of her fervent expression. It was the same kind of zeal when she was first exposed to the power of the abyss, wanting to seek its strength for her revenge.

As an inevitable result, her body was being drawn to its power, as the essence was desired intrinsically by all life forms. Even if she knew it might forever ensnare her soul, her tongue was about to lick the scoop of steamy yogurts on her fingers.

Fortunately, or unfortunately, the moment of temptation was disrupted with a knock on the door that brought the woman back from her instinctive impulse.

"Who is it?! I instructed that no one should be interrupting me at this hour." Yurin shouted at the door.

"It's me. A few of our hideouts had just been raided by the government. The boss has a task for you, go see him at the vessel chamber, it's urgent." The voice was feminine and flirtatious.

"What does he need from me?" Yurin asked, but there was no response. She could already hear the footsteps walking about.

"That bitch... always so cocky." As the boss's secretary, the nameless woman naturally had all the attributes of a boss's secretary.

Yurin erased the intels she sent to Jean moments ago before leaving the room. The bucket of cum was put into the freezer to preserve its freshness. Lilith would be thrilled by the idea of frozen thick creams. Isn't that just ice cream?
