When Akeno stopped releasing her magic energy, Orion was able to gauge her maximum capacity by referencing her released energy to what Rias possessed. Per his estimates, her maximum capacity was somewhere between eight to nine thousand units, putting her firmly at the level of a high-end Middle-Class Devil in terms of magical energy. After some discrete enquiries from Rias and some conjectures, Orion had concluded that the classes scaled with powers of ten, with a thousand units representing the peak of a Low-Class Devil, ten thousand the peak of a Middle-Class Devil, and a hundred thousand the peak of a High-Class Devil. Anywhere beyond that stood the Ultimates, which he didn't consider for the time being, since even Rias' true max capacity without any suppression was barely over the halfway point of a High-Class Devil.
She seems much weaker than she should be. Maybe travelling across realities and being suppressed every time left her with little time to improve her physical and magical capabilities. She clearly has a lot of knowledge, though, giving her an advantage despite her low energy capacity and weak physique.
"Very good, Akeno," Orion praised the sultry woman in his arms as she tried to maintain her demeanor but kept failing miserably due to the heat constantly spreading throughout her body from her breasts. "Now, I will activate my ability to help you recover. It works by accelerating your natural recovery ability. I'll see how much I can speed it up with your current state."
Orion let his hands move in a consistent motion, first gently squeezing her breasts while using his thumbs to flick both her sensitive nubs a few times, then grasping the erect nipple between his thumb and index finger, lightly squeezing it with a firm grip, following up with slow, methodical tugs and twists that quickly earned him weak moans from her mouth as her body trembled, he then repeated the motion, slowly building up Akeno's arousal.
Under normal circumstances, I could never get the opportunity to do this to someone like Akeno. A full, twenty-on-ten beauty with downright no experience with real physical intimacy to speak of is practically mewling in my arms… It's really difficult to hold myself back from taking things to the next level…
Akeno's breathing grew shallower by the second as Orion brought his focus to his specialization, whatever that was supposed to mean, as opposed to just calling it an innate ability like in the section for Rias that held the Power of Destruction.
When Akeno's arousal reached a certain threshold, Tantric was automatically activated. Even though Orion was just as turned on as Akeno, if not more so—anyone would be considering her current weak and sultry state—he had kept his focus on her internals. Normally, he wouldn't have any idea about her magic capacity or anything else that went beyond her physical body, but with Tantric activated, things changed.
His senses were able to probe deeper into her, and he received an instinctive understanding of her magical core alongside the quality of her magic. It was leagues larger than what Rias currently possessed—his knowledge of her true, unsuppressed quantity came only from the system since he couldn't sense any hints of her suppression. Beyond Akeno's quality and max capacity of magical energy, he also got an accurate idea of her natural recovery. Every minute, she recovered one percent of her total energy capacity. He couldn't identify the source of that recovering energy and simply sensed it appearing all over her body and slowly collecting at her core, which was present at the lower part of her sternum, just below her breasts. Logically, since the Devils still ate, he deduced that this magical energy was generated in the same way as humans—by burning calories. He decided to keep an eye on how much energy she was burning to both confirm and make sure his accelerated regeneration didn't end up causing other issues.
Once he had a thorough understanding of her body as she trembled in his arms, Orion finally activated the only ability that he had with Tantric: [Recovery].
"Ahn~" Akeno immediately loud, shaky moan that broke through her lips. She was no longer able to suppress her reactions to the intense heat that was constantly spreading through her body. As arousing as her moans were, Orion forced himself to focus on her internals, specifically her magic. He was worried that if he didn't distract himself, he would be unable to hold back and remove his pants right there.
With the ability's activation, Orion saw Akeno's recovery shoot up to almost five percent per minute from its previous one percent. It might not sound like a significant increase, but it meant that instead of taking a hundred minutes to recover her full energy, she would only need twenty minutes as long as her state was maintained. Another thing to note was that this was just him casually playing with her breasts. Under more intense circumstances, his ability might even reduce the time to full recovery down to less than a minute.
"Tell me, do you feel your energy recovering quicker, Akeno?" Orion asked, opening his eyes and looking at her. He had to gulp as it became impossible to keep ignoring the tantalizing situation in front of him. Akeno's lips were parted, taking quick, shallow breaths that made her breasts rise and fall even as he toyed with them. She had faint hints of sweat on her chest and forehead that made her reddened skin glisten alluringly. He couldn't help but imagine leaning forward and capturing her supple lips in a heated kiss. An alternative image appeared in his mind of him putting his cock between her breasts and covering her face with his cum.
I get what Rias meant when she told me to be cautious. I want to both protect her and ruin her right now…
"I do," Akeno responded breathlessly. "It feels five times faster than usual."
"Let's try to speed things up further," Orion said before putting some pressure on her chest and pushing her down. She didn't show any resistance and allowed him to push her down until she was lying flat on her back with Orion hovering above her.
"Orion-sama…" She gasped, showing hints of hesitation on her face as his hands continued playing with her breasts.
"This shattered mask of yours is much better," he said. "Acting all sultry and mature doesn't suit an inexperienced virgin like you."
"Please~" She bit her lower lip as Orion roughly pinched her nipples.
His response wasn't verbal as he leaned forward and captured one of her nipples in his mouth. He squeezed her breast tightly while sucking the pink nub as if trying to milk her. At the same time, his other hand continued mauling her other breast while flicking her perky nipple with his thumb.
He could feel Akeno's entire body tremble the moment he started sucking her nipples. A loud moan escaped her supple lips as her back arched. Her hands found Orion's shirt and tightly clenched it with a powerful enough grip to tear the fabric even through it was made from his own body.
I need to consider how I will improve my own stats as well. Can't have Rias actually destroy my dick when I try to fuck her.
He spent a good few seconds focusing on her pink tip, sucking and nibbling on the sensitive nipple. Everything he did elicited a different reaction from Akeno, almost as if she were an instrument that he was playing. When he switched to the other breast and pinched her now wet and sensitive nipple with his hand, she immediately took a sharp breath as her toes curled up from the painful, yet pleasurable jolt that shot through her body.
Let alone resistance, Orion felt Akeno push her chest even further toward him, expressing her eagerness to see him continue. The bulge in his trousers was getting more uncomfortable by the second, and he desperately wanted to release it. Still, he didn't want to embarrass himself by acting like an uncontrollable mad dog, so he once again focused on Akeno's internal state to distract himself. Lest he do something to hurt the woman, which might cause a whole slew of trouble later.
Now that he'd intensified his assault on her breasts, Akeno's recovery quickly shot up to ten percent per minute, directly doubling from its previous five percent. By now, she had pretty much recovered all of her energy, so Orion thought of trying something by himself instead of asking her to release more energy.
Since the system said that his race was Klyntar, there was definitely a possibility that there were parallels between him and the Symbiotes from the Marvel Universe, despite his core abilities being focused on Tantric. He wanted to test this theory by trying to siphon Akeno's magical energy into himself, hoping to devour it to enhance his current pitiful reserves of magical energy instead of letting Rias collect everything without providing any benefit to him.
Just as he thought about taking her magical energy, it automatically started flowing out of Akeno, alerting her as she widened her eyes with a panicked expression.
"It's just me, don't worry," he whispered gently, looking up at her with a smile as he extended his tongue and licked her glistening nipple. "Your reserves were about to fill up. Don't worry about anything and focus on the pleasure."
His words quickly calmed her down as he roughly squeezed her breast and bit lightly on her nipple, eliciting a cute squeal from her lips as he nibbled on her other nipple. She no longer had any capacity to continue caring about her energy being siphoned away and closed her eyes, letting the pleasure consume her thoughts.
Two minutes later, Orion felt a little disgruntled as he realized that it wasn't going to be as easy as he had thought to increase his magic capacity to unreal levels.
After absorbing more than five thousand units of her magical energy as it continued to swirl through his body without any container, he finally felt his energy core stirring. It released a devouring force that cleaned out everything freely circulating through his body, leaving nothing outside the core. Unfortunately, all of that energy was exchanged for a paltry increase of a single unit to his maximum capacity.
Magical Capacity: 5/6
While a little frustrated, he quickly accepted the drawbacks when he looked at the sexy woman writhing helplessly under him as she lost herself to the pleasure. His disappointment quickly disappeared as he comforted himself.
I guess I can only continue helping Akeno recover as much as possible. Maybe the constant cycling will increase her capacity as well… The lengths I'm going through to help her… the woes… I'm making such a sacrifice.
His internal thoughts were coupled with him sucking Akeno's nipple with even greater enthusiasm.
