Chapter 50 Dual Cultivation Ability (Part ②)
Edited by: Kanaa-senpai
Aki barked out all sorts of orders, but in reality, he had never actually done anything truly perverted or excessive.
Whether it was the Takamine Sisters or Hamazaki Reina’s group, it was the same for all of them.
What Aki wanted were exclusive “flesh toilets,” not public restrooms.
All his training behaviors were built upon this foundation.
Shinomura Yuki and Aki hadn’t been on good terms for a long time; bullying her occasionally was fine, but going too far would lack class.
After enjoying Shinomura Yuki’s riding skills for a while, Aki pulled her into his arms and began to actively thrust upward.
”Nn… hah… nn…” Shinomura Yuki clung tightly to Aki, her cherry lips subconsciously seeking comfort.
Aki pressed down on her pink buttocks, shoving hard.
Half the head of Little Aki (Aki’s member) stabbed into the even hotter ring of flesh.
”Wuu~” With her little tongue captured by Aki, Shinomura Yuki could only let out a mournful cry.
Then, her dainty body began to tremble and shake uncontrollably.
Little Aki (Aki’s member) rubbed vigorously a few times, happily venting white foam¹ amidst a tightening suction he had never experienced before.
”Whew…” Aki let out a long breath, detached Shinomura Yuki, and gently placed her on the sofa.
There were benefits to having a petite figure; not only was she easy to hold, but her flower valley was shallow.
With a bit of effort, he could experience that sensation of double-layered suction.
As the round ended, Hamazaki Reina finally arrived.
”Uesugi~ there’s still a long time before dawn~” Aki knew what she was hinting at, but before continuing, he had to finish his business.
He closed his eyes to feel his physical state.
His physical strength was slightly depleted, his Mana² had risen slightly, and his energy remained abundant, as if he had an inexhaustible supply of Essence³.
However, after successive battles, Little Aki (Aki’s member) was heavily worn, slightly swollen, and numb.
(Well, it’s also possible the enchantment wasn’t skillful enough and the backlash hit it…) Aki held Hamazaki Reina, letting his hands wander from front to back, but he simply wouldn’t mount her.
Hamazaki Reina panted continuously, her spring waters flowing.
The emptiness and itching deep in her flower valley remained unsoothed.
Her soft little hand caught hold of Little Aki (Aki’s member) as she actively lifted her full, rounded jade mounds.
”Uesugi… quick, come in… nn, come in…” Little Aki (Aki’s member) followed the familiar path all the way to the end.
The sensation of the flower valley being stretched to its fullest made Hamazaki Reina feel incredibly comfortable.
After a few seconds, seeing that Little Aki (Aki’s member) had no desire to move, Hamazaki Reina gave Aki a resentful look.
Her slender, beautiful legs exerted force to prop up her body, and she began to serve him actively by lifting her hips and thrusting her waist.
Sensing Hamazaki Reina’s intention, Aki smiled slightly and gripped her thin waist tightly, not letting her move.
”Nn?” Hamazaki Reina tilted her head to look at Aki.
”Uesugi, what’s wrong?”
”Nothing, I just have something I want to ask you.”
”What is it?” Unable to create friction, Hamazaki Reina could only twist her buttocks to alleviate the hunger in her flower valley, using her flower core to constantly grind against the head of Little Aki (Aki’s member).
”You can ask while we do it; it won’t affect anything.” Aki laughed.
”I think it does affect things.”
”What on earth is it?”
”About why you all targeted me in the first place, and why you’ve been pestering me to do this…” Aki paused, his lower abdomen thrusting hard twice before he continued, “Don’t you think you owe me an explanation?”
”Oh… nn…” Hamazaki Reina’s legs went weak, and a numbing sensation spread through her entire body.
Before she could savor it, Aki stopped moving again, making her gnash her teeth in frustration.
”What… what explanation?” Hamazaki Reina looked bewildered.
”We just thought you were good-looking and looked like someone easy to bully…” Women were born actors; Hamazaki Reina’s confused eyes and innocent little expression were perfect.
If he didn’t already have an idea of the truth, Aki definitely would have been fooled.
”Are you sure?” Aki’s hands gripped her thin waist and pulled upward while he inhaled, pulling back his abdomen.
”Nn~” Feeling the foreign object leaving her body, Hamazaki Reina narrowed her eyes in pleasure.
”Hmph!” Aki gave a cold snort.
His hands pressed down hard while his lower abdomen suddenly surged upward.
Hamazaki Reina’s emerald eyes flew open instantly, and she murmured with a look that was half-crying and half-smiling, “Ah… yes… right there… harder…”
”In your dreams.” Aki curled his lip and stopped moving again.
Little Aki (Aki’s member) kept sending signals that it wanted to move, but when the big brother has business, Little Aki (Aki’s member), as the subordinate, can only listen obediently.
”Move… Uesugi, move a little.” Having experienced that intense thrust, Hamazaki Reina felt her flower valley was even more sore and itchy than before.
She said with a sob in her voice, “That really was the reason…”
”I know I’m pretty popular with girls, but there was no need for you all to fixate on me so hard, right?” Aki remained unmoved, saying calmly, “This week I’ve been busy looking for Senior Rias, and you’re already craving it this much. Why didn’t you go find other men?” Even though he spent all day running to the Occult Research Club (ORC), Aki hadn’t forgotten to keep an eye on Hamazaki Reina and the others.
If he discovered they were being targeted by some yellow-haired punks, he would definitely stop it.
But if they were actively hooking up with men…
Aki wouldn’t waste any more energy on them.
Being naturally lewd is different from being forcibly trained into a slut.
For the latter, as long as you stop it in time or they don’t run into a yellow-haired punk, they’re just girls who are a bit horny.
If men can be horny, why can’t women? But if it’s the former…
Aki can’t keep people tied to his side forever.
He can stop it once or twice, but he can’t stop it for a lifetime.
Rather than being cuckolded, it’s better to be the one doing it to others.
He could just treat them as “c**m bins” and call them over for a round whenever the mood struck…
Cough, cough… forget it.
He didn’t want to have too many “fellow travelers” on the same path.
Hamazaki Reina’s expression changed, and she said angrily, “What do you take us for?”
”Don’t forget, you’re the ones who forced yourselves on me.” Aki didn’t panic at all.
Whether Hamazaki Reina was acting or expressing her true feelings, he had a solid argument.
”I find it hard to imagine how ‘virtuous’ girls can be when they take turns on a boy three-on-one during their first time.”
”It wasn’t like that! If we hadn’t discovered you could help…” Hamazaki Reina almost blurted out the real reason in her haste.
Luckily, she reacted in time.
But being treated that way by Aki still infuriated her.
The more she thought about it, the angrier she became; the more she gave in, the more she felt cheated.
Hamazaki Reina said angrily, “Fine, I’ll invite Yukina and the others to a mixer tomorrow.” Aki said expressionlessly, “In that case, you won’t need to contact me anymore.”
”You…you…” Hamazaki Reina felt a pang of sadness. She had only said it in anger, but she hadn’t expected Aki to be so heartless.
She felt incredibly wronged, her mouth opening and closing but unable to utter a complete sentence.
Looking at the tearful blonde beauty, Aki felt a pang of pity.
He could obviously see that Hamazaki Reina was just talking out of spite, but there was no room for negotiation on this matter—it was a bottom line.
Moreover, Aki couldn’t soften at this moment; if he did, all his previous efforts would be wasted.
Under the cold moonlight, Hamazaki Reina bit her lip and remained silent, forcing back the tears that were about to slide out of her eyes.

Aki turned his head away, not looking at the girl’s stubborn and aggrieved expression; he was afraid he wouldn’t be able to resist comforting her.
After a stalemate, Kurumizaka Ruri couldn’t watch any longer.
”Reina, just tell Uesugi.” Kurumizaka Ruri pinned close to Aki, pulling his arm between her lively, bouncing “big rabbits.”
”Uesugi has already entered the Hidden Academy, and his strength has surpassed ours. Even if we don’t say anything, others will eventually.” Hamazaki Reina turned her head away sullenly, refusing to speak.
She had the look of “if you want to talk, then talk, but I’m not saying anything.” At that moment, Sasaki Yukina also walked over.
While embracing Aki’s other arm, she kissed Hamazaki Reina’s small mouth.
Her meaning was obvious: she hoped Hamazaki Reina would be more frank.
Two votes in favor, one against.
As for Shinomura Yuki… she was just a small follower; she didn’t have the right to vote.
Even if she did, she couldn’t vote for the time being.
Because she had enjoyed herself too much, Shinomura Yuki still hadn’t come to her senses.
Kurumizaka Ruri gave a giggle, kissed Aki’s lips, and began telling the story from the first time they saw him.
”The three of us, during the testing at the Hidden Academy…”
”Reina’s eyes are quite special; she discovered that you can…” Listening to Kurumizaka Ruri’s explanation, Aki slowly began to move his hips.
He wasn’t good with words and didn’t know how to coax girls, so he could only use practical actions to comfort the grieving Hamazaki Reina.
With the cooperation of Sasaki Yukina and Aki, Hamazaki Reina soon couldn’t help but start moaning.
Aki had originally intended to use the coercion of Little Aki (Aki’s member) to make Hamazaki Reina unable to endure, hoping she would beg for mercy and tell the truth.
He hadn’t expected Hamazaki Reina to care so much about his opinion, which momentarily threw him off his game.
Instead of a tool for coercion, Little Aki (Aki’s member) became a tool for reconciliation.

Glossary:
Notes:
• Aki – Reincarnated with a System interface and evolving Devil bloodline, he calls himself a ‘considerate scumbag’ and copies talents. Known as Uesugi, he bears the enchanting ‘Little Aki’ trait, wields Dual Cultivation and Mana‑Lightning Flash, leads the Occult Research Club, and once slept with Rias and the Takamine sisters, now dating both while resisting full Devil rebirth.
• Hamazaki Reina – Blonde hair, emerald eyes; in a modern school uniform with a miniskirt and black silk stockings. As ‘Big Sister’/‘Boss’ of Kuoh Private Academy’s trio, she pushes Aki to grow stronger, now obedient, and uses Insight Eye to exploit his bloodline. Part of a four‑person group dependent on Aki’s constitution, summoned by phone late at night.
• Shinomura Yuki – Blonde, sharp‑eyed punk with yellow hair and tsundere vibes, outwardly a bandaged male thug at Kuoh Academy but actually a petite mixed‑blood demon girl in disguise. She despises men, uses Disguise talent, joins Aki’s group after a magic surge, targets him, and secretly likes the Hamazaki trio.
• Rias – Rias Gremory, the 17-year-old pure-blood High-Class Devil and President of Kuoh Academy’s Occult Research Club, is the authoritative Crimson Ruin Princess of Kuoh Town—long crimson hair, crystal-like crimson eyes, and an explosive, elegant figure always clad in her school uniform. Determined and observant, she fiercely protects her peerage, mentors Aki as a big-sister figure, oversees his training, and is currently frustrated by her inability to reincarnate him, driving her to meticulously facilitate the ritual as both leader and guardian.
• Kurumizaka Ruri – Gray-blonde short hair, pink eyes, petite and cheerful, she’s a mischievous teen from Imaizumin Chi wa Douyara Gal no Tamariba ni Natteru Rashii—now at Hidden Academy as a silver-haired, twin-tailed girl with a large bust and pointed chin, part of Reina’s trio. Clingy and affectionate, she teases Aki openly, shares her motives clearly, and proactively pursues her desires. She offers her empty house for their meetings, wears black pantyhose, contributes Mental Resistance, and is pragmatic yet curiously intrigued by mixed-blood races.
• Sasaki Yukina – A bold, seductive freshman at Kuoh Academy with long peach-pink hair, purple eyes, and a statuesque athletic build—noted for her large chest, long fair legs, and white ankle socks—she’s the most physically capable of the four newcomers, rivaling Hakada Tetsuya in strength. As the strongest of Reina’s trio and Aki’s long-term partner, she initiated their intimate encounter, granting him a power boost via her ‘Physical Activation’ talent, which extracts mana for enhanced strength, endurance, and rapid recovery. Observant of magical anomalies—especially the Succubus’s power-sharing—she’s competitive, virginal, and a key member of Hamazaki’s group, having knocked Aki unconscious to test him and providing critical intel on Shinomura Yuki, while advocating honesty with him about their motives.
