The week had gone by without any major incident as Issei's extreme training with Asia, Kiba, and Koneko eventually got him up to the level of a weak Low-Class devil from an average human, both in terms of physique and in terms of magic. Unfortunately for him, he wasn't able to last until the end at all, losing out on the promised benefit that Rias had given him for completing the training.
On the other side, Rias and Akeno went through an even more intense training experience, going so far as not to sleep at all and putting all of their energy into training constantly for seven days consecutively. A large part of the reason that they could go so far was Orion, at least on Akeno's side. Rias had an unreal level of endurance and stayed awake and fully conscious for the whole seven days by sheer will alone, aside from the nutrient solutions that she had introduced to everyone for the purposes of their training. It was apparently something common in the Underworld since Devils still relied on external nutrients to recover their energy.
However, for Akeno, it was because Tantric's Recovery ability was a comprehensive regeneration of everything from stamina, magic, and mental energy. Tantric's exhaustive recovery ability went so far as to handle even sustenance, making her free from the need for any nutrient solutions or food. Orion theorized that Tantric was producing its own energy that depended on either intense emotions or was harnessing raw sexual energy. But he didn't reach any concrete conclusions over the week of experimentation.
Of course, that wasn't all he did. Since he'd already left a part of himself on Akeno, controlling it to pleasure her barely required a few thoughts, allowing him to freely explore Kuoh by himself while she and Rias trained.
Still, while Akeno had relied on him completely to survive the intense training, Orion was well aware that he had barely done anything to help Rias recover, aside from healing a little scratch that she got on her arm accidentally. She was just leagues better in terms of strength, willpower, and endurance. Beyond the physical limitations of her current body that had merged with this reality's Rias, her mind was on a whole different level.
Akeno, however, for the sake of training, had been in a constant state of intense arousal and heat throughout the week as Orion, in his disembodied slime state, replaced her bra and spent the entire week toying with her tits. At first, she was deeply embarrassed by the situation, unable to cast a single spell under the state of constant arousal as he stimulated her breasts. But after enduring the unceasing arousal for so many days, she had pretty much lost all her shyness and started freely expressing her arousal, going as far as to lean into the feeling during battle.
The week-long training may not have taught her new tricks, but it had allowed her to function at her peak state for a far longer duration due to the significantly enhanced regenerative capabilities that came with her being aroused all the time. Of course, that didn't mean there were no improvements. In just that week, she had gone from a max capacity of barely nine thousand units to almost ten thousand, bringing her very close to the level of a peak Middle-Class Devil both physically and magic-wise. Rias, on the other hand, had somewhat recovered from the suppression but was still lagging behind Akeno in both the energy and the physique department. Yet, even with severely suppressed stats and magic, she thoroughly dominated every spar that she did despite Akeno being constantly recovered to her peak.
Finally, on Saturday evening, the redhead had called the training off and went off to her apartment, leaving Akeno to do the same and rest well during the night before the battle.
"Orion-sama," Akeno said with an aroused smile. "I think you can stop teasing my breasts now. I'm not going to exert myself anymore after all."
[How about I help put you to sleep? It will let you recover much better than otherwise. Interested?]
"Okay," She said without any hesitation. After so many days, the two of them had established a rapport and had some mutual understanding with each other.
She waved her palm and formed a red circle under her that sported the crest of the Gremory Clan. With a flash of crimson, she teleported to her apartment bedroom.
"Here we are," she said, and started unbuttoning her corset and shirt. There were no hints of hesitation or shyness on her face as she quickly got rid of everything without any worries about Orion's presence. That was to be expected. Even Rias, completely averse to him touching her in any sort of sexual way, wasn't bothered in the least by exposing herself; Akeno was even less so.
After seeing the way the two women trained, Orion had come to understand that the reason was a mix of both the general lower inhibitions that Devils had and the fact that Rias' powers kept destroying Akeno's clothes. It was easy to imagine the two women choosing to train together without any clothes due to Rias constantly destroying their clothing items.
[You look really sexy, you know that?]
"Thank you, Orion-sama," Akeno said before approaching the bed. "What about this?" She hooked her finger under the bra, which was just two black cups that covered her breasts without any straps to hold them in place.
[Tell me, are you confident in beating all of Riser's Peerage by yourself?]
"W-what are you talking about?" She paused just after sitting on the bed.
[I'm asking you about your confidence in your current strength. Training with Rias helped you boost your magical energy almost to the peak of a Middle-Class Devil and even helped you make your spellcasting significantly quicker and more efficient. Do you think that's enough to beat Riser's Peerage?]
"Maybe not his whole Peerage, but with your support, I should easily be able to handle his Queen," she said. "I'm the only one who isn't weak to her specialty of explosions since I can handle her from a distance."
[You can't be that naive, Akeno. You have less than half the number of people that they do. What's going to happen when she gangs up on you with two Bishops? What if Koneko gets taken out by a sneak attack and half of his Pawns swarm you? Worse, they could keep Kiba and Issei occupied long enough that the Rooks and Knights are free to support his Queen. What happens then? Can you be sure that Rias won't end up having to face most of Riser's Peerage and him all by herself?]
"I-I…" She couldn't come up with an answer. "I'm not sure…"
[I have a suggestion. If you give me unrestricted access to your body, I will be able to provide you with a much-needed enhancement to both your physique and your max magical energy capacity.]
"I…"
[Don't worry, unrestricted access does not mean penetration. I will leave your hymen intact to allow you to retain your virginity. But I need more intimate access to your body if I want to provide you with the enhancement effect. What do you say?]
"How will it work?" She asked with hints of hesitation. Compared to the previous week, her shift was understandable. Spending a whole week with your breasts constantly being teased and toyed with was bound to make anyone lower their inhibitions, let alone a Devil like Akeno, who had lowered inhibitions on a racial level.
[It will be directly linked to your state of arousal. The more horny you are, the stronger the effects. If I bring you to an orgasm in the middle of battle, not only will you be regenerated to your peak state like usual, but your magic energy and physical stats will also double comprehensively, bringing even better benefits than having your own Twice Critical. It will only last for a few minutes, though.]
This was something that Orion had been sitting on for a few days now. After three days of teasing and toying with Akeno's breasts while constantly using the Recovery ability of Tantric, it had moved up to level two, unlocking a new ability for him.

Stats (Expand)
Beyond Tantric, there wasn't anything significant of note. His comprehensive Physique and Mind stats had naturally increased by a tenth of a unit in each subsection without any effort from him, and his magic had gone up from six to twelve units after devouring large amounts of Akeno's excess magical energy throughout the training sessions while also enjoying the benefits of Territorial Authority that Rias was, technically speaking, stealing.
With that came the worrying information that with each increased unit, the required energy increased far too quickly. Starting from five thousand units, it went to ten, then it went to fifteen thousand. When getting his energy capacity from eleven to twelve, he had sucked away over fifty thousand units. He surmised that it was because he didn't yet have the dedicated ability through Tantric for it yet, and was simply going off of instincts, wasting a large chunk of the energy that he took.
Aside from him, nothing much had changed on Rias' side, save for her maximum energy capacity going from the mid-six hundreds to the late four thousands, a little less than half of what Akeno had right now. This was less improvement and more a gradual release of the suppression she was under after travelling between realities.
Coming back to the present, Orion observed Akeno's hesitant expression through his deep perception of her body without directly looking at her and waited for her hesitation to turn into a decision. While he could totally provide the enhancement to her without going any further, he wanted to do more than just touch her breasts. The primary reason was just that he was greedy and wanted more of this unrealistically sexy woman, but another, more practical reason was a notification that he received when he'd hit level two in Tantric.
Subordinate Host Conditions Met.
Activate Subordinate Bond?
He wasn't yet sure what those conditions were—whether they had to do with levelling Tantric, or if it was just about emotional acceptance. But he did receive an accompanying infusion of information that gave him the details of the subordinate bond along with the process of forming it. The main thing was that it was a slower process than the prime bond, requiring hours of intense stimulation for the host. Considering his specialization's nature, it didn't surprise him. What surprised him was that it was a fully temporary bond, allowing him to break it off whenever he wanted without any consequences. Whether there were other kinds of bonds was something that he planned to explore some other time. But the temporary nature of the bond melted away Orion's resistance toward forming the bond with Akeno.
Akeno's hesitant expression soon turned resolute.
"I'll do it," she said.
[Say it nicely, Akeno. You know how I taught you. I'm helping you be a better servant for your mistress, right?]
Akeno suddenly blushed as Orion's words echoed through her head.
"P-please do with my body as you please, Orion-sama. As long as it doesn't involve penetration, I am willing to give myself to you to do with as you please," she said with a sultry smile, bringing her hand between her legs as she spread them apart. "Touch me all you want."
[Attagirl, lie down on the bed now and close your eyes. Leave the rest to me.]
