Chapter 296 Returning & Expansion


Edited by: Kanaa-senpai


 The girl’s Flower Valley tightened violently, every muscle in her body bunching under the wave of pleasure. A jolt of electric pleasure ripped through the inner meat, and a heavy, hot, honeyed fluid sprayed out like a fountain.


 The room light from the ceiling cast a soft glow over the scene; Aki was still thrusting in and out of the girl’s Flower Valley.


 Siris and Karlamine neither tried to stop him. Though she was already limp from the climax, Siris leaned on Karlamine for support and reached out with a delicate hand to hook her fingers around Aki’s neck.


 She lowered her long, fair legs from Aki’s shoulders, wrapping them tightly around his waist instead, following the rhythm of his thrusts to guide the Great Dragon deeper—deeper than it had ever gone before.


 Thrust after thrust after thrust, and after a long, unknown time, the Great Dragon, hidden in layer upon layer of soft, sweet flesh, finally hungered for release.


 Aki felt a jolt of numbness at the base of his spine; it was as if all the blood in his body was rushing through his veins into his lower half, pulsing as it forced its way into the Great Dragon. With a violent, rhythmic twitch of the dragon’s head, he released everything deep into the girl’s Flower Valley.


 The hot Life Essence poured in, so much that even without Aki penetrating the Flower Palace (Hanamiya) further, the girl’s fair, slender lower belly was visibly swollen and tight.


 ”Wuu?… Master… AkiMaster… it’s all inside… mn?… so much… so hot… my stomach is stretched tight?… already… it’s already completely filled… uu… Main God?… my belly is… full of Master’s Essence?… uu-mn?…” Siris whimpered, her voice soft and breathless.


 …………


 The next day, Aki rose early once more.


 Looking at the two girls beside him, their bellies still slightly rounded, lost in deep sleep, he felt a pang of pity—but he woke them anyway.


 Today, he and Ravel were returning to the Human World. Not just the two of them; Yubelluna and the other fourteen girls were coming along. Since he had decided to make them his Peerage (retinue), it was only natural to keep them close.


 ”Once Ravel starts Breaching, and receives her own Evil Pieces, we can sign the Contract immediately,” Aki stated, his tone focused.


 They had left as two but were returning as sixteen. The once-spacious Activity room suddenly felt incredibly crowded. After briefly explaining the situation and the arrangements for Yubelluna and the others to Akira, Rias made a quick decision: expand the Villa. Until the construction was finished, they would have to find a place to stay temporarily. Fortunately, if there was one thing Aki had plenty of, it was female friends; there was more than enough room for them to stay one person per house. As for their long-term plans, Yubelluna and the others wanted to find their own path in the Human World instead of attending Kuoh Academy. While the girls looked young and beautiful, only Twin Lolis was a genuinely sixteen or seventeen-year-old; the rest were all over twenty, well past the age for formal schooling. However, Devils are long-lived, making it hard to judge their true age from appearance—though their physiques were a more accurate indicator, and Aki could confidently say that everyone’s statements were true, except for Xue and Isabella. On the other hand, the Gremory household wasn’t short of money to feed fourteen people, but they felt somewhat embarrassed, and more interested in exploring the Human World than staying in a stuffy school.


 With summer vacation fast approaching, Aki spent the next few days juggling tasks: he comforted the girls in his two major organizations, helped them review for final exams, and then devoted the rest of his time to helping Rias and the others reach higher ranks. The peak SSS Life Essence had a big effect on Rias and the others, but due to a lack of prior experience, they hadn’t yet reached Breaching. However, after several days of rotation, almost everyone in the Shinken Club except Asia and Yuuto had reached SS-Rank. Rias, Himejima Akeno, and Amano Yuuma (Raynare), who had a Soul Contract with Aki, were on the verge of Breaching to become SSS-Rank Special Devils.


 Immersed in a world of breasts and buttocks, Aki felt time was passing quickly. After successfully passing the final exams, summer vacation officially began. He had planned to raise Rias and the other two to SSS-Rank in one go, and then begin treatment for Xue and Isabella. On the night of the full moon, they would continue signing the Soul Contract. Their schedule was packed—even his efforts to get closer to Naruse Mio and Maria had to be postponed.


 But man proposes, God disposes. Summer vacation had barely begun when an unexpected event disrupted Aki’s plans.


 …Underworld Abyss. Her power greatly increased, having fully mastered the ominous power, Katarina disgustedly drove away all the people her subordinates had brought. This was her third day back in her family. The Life Essence she had deliberately left inside her had been fully digested, and her power held steady at the Super-Devil level.


 However, Katarina couldn’t be happy. Not only was she unhappy, but she even felt a sense of emptiness. Some members of the Leviathan family noticed the change, but no one pointed it out, and they even specially picked a group of exceptionally attractive Devils to give to her. After being gone for a week, Katarina suddenly returned, her power greatly increased. Knowing what she had been doing before, the captured members of the Leviathan family knew perfectly well what had happened to their beloved patriarch.


 Their actions weren’t wrong; Katrea had initially thought to use this approach to ease her inner and physical emptiness. However, she felt only indifference and disgust toward the male Devils, but showed some interest in the beautiful, well-proportioned female Devils. Indeed, Devils were very open about s*x, offering themselves to an equal number of men and women.


 Katrea initially wanted to keep a few of the most attractive female Devils, but in the end she decided against it. While she wasn’t a genius like Akira, she knew this was like drinking poison to quench thirst.


 Time slowly passed, and the dark-skinned, mature woman increasingly missed the week she had spent in the Kuro Room.


 While Aki had moved on to other beauties, completely forgetting her, she had reached her limit.


 August 3rd, the first day of summer vacation in Japan. Gazing at the luxurious four-story building before him, Aki secretly marveled at how fast things got built in this world. In a world with magic, even the so-called “Celestial Empire speed” had to concede defeat. Entering the building and taking a quick look around, Aki decided to move in immediately. Compared to the Takamine Family, this seemingly ordinary building was a luxurious, indulgent place on the inside. First, unlike normal buildings, this villa occupied more than three separate structures, divided into three parts and arranged symmetrically around the central room. From the outside, it looked like a super-large single-level apartment stacked four stories high. There weren’t many rooms, but each one was ridiculously large.


 Aki’s room was on the top floor, right in the center. The decor was simple, mostly white and blue. Besides a super-large bed surrounded by white curtains in the middle, there was only an L-shaped blue velvet sofa and a small table. Huge floor-to-ceiling windows were covered by white curtains. The soft light gave the room a sacred and mysterious feel. Instead of tatami mats or tiles, the floor was covered with a light blue wool rug.


 Aki’s first thought when he saw this room was that it was perfect for a s*x party.


 —


 Summary:

 Aki successfully completes a session with his current female companions before preparing to return to the Human World with an expanded group. Rias authorizes the expansion of the villa to accommodate the newcomers while Aki balances his academic responsibilities and harem management. Meanwhile, Katerea struggles with deep-seated emptiness following her return to the Leviathan clan.

 Trivia:

 Yubelluna and the other fourteen girls were former members of the Phoenix clan.

 The new villa expansion is necessary because the returning group has increased to sixteen people.

 Only the Twin lolis are genuinely teenagers; the others are over twenty years old.

 Aki’s Peerage members, specifically Rias, Akeno, and Yuuma, are on the verge of reaching SSS-Rank.

 Katerea’s current power level has stabilized at the Super-Devil stage.
