Ethan explained the events of the previous night—including the Mountain Goblin and the Fallen Angel Raynare, as well as his Devil form—while rubbing his little Ethan against various parts of Rias's body: her beautiful legs, jade-like hands, massive breasts, and red hair.
Ethan planned to recruit Amano Yuuma. Although the woman had a somewhat terrible personality, her abilities were certainly useful. Stopping her from committing any atrocities and then properly training her would make her a reliable helper.
Rias wasn't at all concerned about the Mountain Goblin and the Fallen Angel.
The Mountain Goblin was an established target, and she naturally had the relevant information. It was within her expectations that Ethan could easily defeat such an opponent.
As for the Fallen Angel... Rias was the administrator of Kuoh Town; how could she not know about the presence of other factions on her turf? She was not only aware of the Fallen Angel presence but also knew they seemed to be plotting something.
However, since it didn't affect ordinary people and had no bearing on her or her immediate circle, she had ignored it, which amounted to letting them be.
Compared to these issues, Ethan's Devil form was far more intriguing to her.
After having Ethan assume his Devil form, Rias stroked the jet-black, broad wings for a while, then curiously grabbed his powerful, whip-like tail.
"If you didn't lack Devil horns, I would think you were a remnant of the Ancient Devils."
"Ancient Devils?"
Ethan was confused. Where did this completely unfamiliar term come from?
The red-haired, large-breasted Devil noblewoman posed in various wanton positions, cooperating with Ethan's movements, using every inch of her skin to soothe his massive member.
Rias let out continuous gasps of pleasure, explaining in broken sentences the history of the Ancient Devils and the change in his magical power.
While his little Ethan was busy, Ethan wasn't idle either, meticulously absorbing the knowledge Rias was imparting.
The so-called Ancient Devils were, as the name suggests, the oldest batch of Devils, their origins tracing back to the dawn of the world.
At that time, there was no concept of factions like Devil Clan, God Clan, Human Race, Dragon Race, etc.
The world was simply divided into three major factions: the Devils of Hell, the Gods of Heaven, and the Alliance of the Mortal World.
There was no possibility of reconciliation between the three powers, especially between the Devils and the Gods, who were constantly at war.
Endless conflict, however, would drain even the most powerful races. Various methods to replenish soldiers began to appear.
The Maozu (Demon Clan/Current Devils) and Angels were born out of this necessity.
Time is the most potent force. After an unknown period and following a war that is no longer clearly remembered, the original Gods and Devils perished, and the Mortal World Alliance also fell apart.
While the Maozu and the God Clan rose to power, they also inherited the grudges of the previous generation. But with the strengthening of other races in the mortal world, especially the Dragon Race, both sides finally tacitly ceased hostilities after the Great War ten thousand years ago.
Though it is said that the Seventy-Two Pure-Blooded Devil Families are few, the reality is that truly pure-blooded Maozu (Current Devils) are scarce. The true Ancient Devils have long since vanished.
One reason the God Realm and the Devil Realm ceased fighting was the cautionary tale of the Ancient Gods and Devils.
Rias is the next head of the Gremory family, meaning her bloodline is undoubtedly as pure as it gets, but besides a pair of Devil wings, she has no other Devil characteristics.
In other words, Rias has only 33.3% of the Ancient Devil's appearance, yet she is a Pure-Blooded Devil.
Ethan has one more jet-black tail than Rias, and his wings look closer to a Devil's.
However, he lacks horns, and his wings are only similar, not the same as the ferocious wings of the Ancient Devils.
Rias speculated that Ethan might originally contain extremely rare Ancient Devil blood—no, not bloodline, but perhaps just a gene.
If not for the influence of the Evil Pieces, it might never have awakened in his lifetime.
Ethan neither confirmed nor denied this. He knew it had nothing to do with the Evil Pieces. Even if it was due to an external force, it was the power of his dual cultivation ability.
However, there was no need to be so explicit about this; all that mattered was that it wasn't a bad thing.
Ancient Devils or their descendants might be monitored for fear they could reignite a massive war, but merely possessing some of their genes could actually make many Maozu look upon him favorably.
After all, this was considered a noble lineage. Although mixed, the bloodline might not necessarily be inferior to that of the current Pure-Blooded Devils.
Putting aside the genes Ethan might have inherited from his parents overseas, the main focus was the relationship between his Qi (Magical Energy) and Magic Power.
After breaking through to A-rank, if one practices both Martial Arts and Magic, as long as one reaches A-rank, the other will slowly break through as well, driven by the evolution of the life essence.
However, this change would be somewhat prolonged compared to an active breakthrough.
Simply put, even if he couldn't actively use Intermediate Magic Extraction, Ethan would slowly become an Intermediate Magician—just at a slower pace.
As Rias finished speaking, Ethan's massive member also felt ready. He lay down on his back and placed Rias on top of himself, though they were facing opposite directions (a Sixty-Nine position).
He parted her fair, tender legs and began kissing and licking her continuously twitching, pink flower-valley. Rias lay over Ethan's thigh, her full, round breasts pressed into a flat shape.
Her delicate flower-valley was being served by his mouth and tongue. The girl's body stiffened, then softened against Ethan's body. Her cherry lips parted slightly and slowly enveloped his throbbing, fiery red member.
"Wuh... Mmm... Wuh Wuh..."
Even though she opened her small mouth as wide as possible, there were still two-thirds of his enormous member left outside when the hot head touched her throat.
For Rias to fully swallow his little Ethan, she would have to learn deep-throating. It was otherwise impossible.
In this position, they serviced each other. Feeling the petal-path begin to tremble and torrents of nectar-like fluid shoot out from the girl's body, Ethan no longer held back.
He thrust his hips gently, pressing against her soft little tongue, and began to release the thick essence he had held for over a day.
With his colossal member blocking her mouth, Rias could only try to swallow the hot, viscous white fluid, but there was simply too much for her to consume all at once.
The overflowing essence caused the girl to cough repeatedly. Her exquisite cheeks puffed up high, and the essence she couldn't swallow continuously spilled from the corners of her mouth, some even trickling down from beneath her small, fine nose.
After climaxing together, Ethan embraced Rias for a while longer in the bathroom, then cleaned up the residual traces on their bodies, finally ending this master-servant activity.
When they stepped out of the bathroom, Akeno Himejima and Koneko Toujou both had flushed faces, their eyes darting with reproachful glances towards Ethan and Rias.
The soundproofing in the bathroom was inadequate. Rias, caught in the heat of passion, couldn't suppress her voice. Her ecstatic, reverberating moans were enough to make both of them outside involuntarily clamp their legs together, their own flower-valleys becoming moist.
Forcibly ignoring their expressions, Rias calmly stated, "Alright, go and wash up. We have class soon."
"Oh my, oh my, it's only because you two were in there for so long..."
Rias glared at the muttering Akeno Himejima. "Hurry up!"
"Yes, yes, my President~"
"Ethan, this is a uniform tailored to your size. Before, you couldn't spread your wings, so I didn't give it to you. Now is the perfect time."
After putting on his new uniform, Rias took out two brand-new male uniforms from the closet.
Having already been completely intimate, there was nothing to be shy about. Ethan pulled off the towel around his waist and immediately put the uniform on.
He checked himself in the mirror. Hmm... aside from the unfamiliar feeling of going commando, the size seemed a little small.
Rias noticed this too and curiously stepped forward to measure him.
"Oh? Ethan, you've grown taller recently. This was tailored to your size before the summer break. Looks like I'll need to order a few new sets."
Ethan was momentarily stunned. He was very conscious of his height and had measured himself just two days ago—there was no change...
Looking at the tall, slender Rias, he was surprised to find that they were almost the same height.
Rias was 172 centimeters, and Ethan was 170 centimeters, only a two-centimeter difference. However, due to gender stereotypes, Rias generally appeared taller than him at a glance.
Ethan briefly considered the reason and quickly understood.
Similar to his Talents and True Devil Form, his original height and physique were suppressed by the Cuckold Template and couldn't be changed.
After breaking through to A-rank, he could finally continue to grow, bringing him one step closer to escaping the fate of the cuckold.
