Issei was sitting on his bed, trying to fall asleep, but it was proving to be a difficult affair, his mind turning towards his plan with an annoying frequency, feeling constrained by its requirements. He was still in the early stages of it, and he needed to stay relatively passive for the first few months, at least until his new peerage get used to his constant presence, giving him the opportunity to walk around without getting instantly identified as a threat.

But his dragonic instincts turned out to be a true inconvenience. He was in an unfamiliar residence with dubious security measures, and his instincts were begging him to secure it with the strongest spells available for him, to conceal it from anyone that might try to leverage his vulnerability. Unfortunately, doing so would reveal his hand prematurely and ruining everything he had been struggling for the last few months.

A compromise, he decided as he stood up with a sigh. While he couldn't use his own spells to secure the building, there was no harm for him to patrol it as long as he made sure to stay hidden. Confirming the lack of threat with his own eyes would help him to relax. He took a deep breath as he focused on his magical signature, suppressing it to a degree that would avoid triggering any alarms, then stepped out of his room.

The corridor was illuminated by flickering electric lights that strangely felt like torches, creating dancing shadows on the ornately designed walls, decorated opulently. Such a waste, he decided. If he had just a sliver of the riches that were represented in the corridor when he first discovered his sacred gear, things would have developed much easier. The lack of funds had delayed his plans quite a bit in the past when he was still weak, forcing him to focus on acquiring money instead of training.

It was a pity that his acute need for money was a thing of the past, his new problems couldn't be solved by swiping a gold-plated lamp-post. He still required a lot of resources, but those weren't the kind that could be exchanged for money or gold, locked behind impenetrable walls by the key players, slivers of it may be bequeathed to distant allies. Luckily, Issei recently moved to a point where he had the ear of one of the most prominent heiresses of the underworld, sister to the Lucifer himself. If all went well, he would soon have preferential access to one of the best vaults in existence.

With that in mind, he ignored the rather pricey artifacts on the walls, and started walking. He allowed a thin layer of his magic to spread away from his body, allowing him to sense the people through the walls. He could sense Kiba in the nearest room, but he just passed the door without bothering to check the room. Issei could sense that he was alone, and he had no intention on peeking at another dude.

There was no one else on the level he was in, but he could sense three more upstairs, and a complicated, but very interesting, magical seal on the basement. Most likely Rias' hidden bishop, he decided. During his research, he managed to discover that Rias has a bishop that she was forced to seal because of their powers, but that was the limit of the information he was able to acquire. Despite the temptation, he elected not to go downstairs to check. He wasn't a slouch when it came to warding, but he lacked finesse. His preference was either to bulldoze through them, or sneak inside without disturbing the defensive matrix. Unfortunately, neither of them was a good fit to discover the secrets of her bishop, who was protected by warfare-level wards.

But things were different for the wards that stood between the first and the second floor, where Rias, Akeno, and Koneko's bedrooms were. He focused on suppressing his magical presence even more, bringing a feature he liked to call hunter mode. With that on, the poorly made alarm ward that separated their bedrooms from the boys' proved no barrier. He managed to walk past it without triggering anything.

He walked to the upstairs corridor, getting a sense of the room without making it extreme. The nearest room, he could sense Koneko's presence inside. He carefully reached for the door, doing his best to stay silent as he opened the door. But the moment he started twisting, he heard a hiss from inside. He had been noticed, he realized. Apparently, her nekomata senses were even sharper than his assumptions. He pulled back, just as careful, waiting at the corridor a few seconds to make sure she hadn't actually woken up.

Luckily, she kept sleeping, leaving him free to turn to his next target, the sadist queen of lighting, Akeno. He hoped that without a racially-enhanced hearing, he would have an easier time sneaking into her room. Still, he was careful as he pulled the door open, waiting for a moment to confirm that Akeno was deep in sleep before stepping inside. The first thing he noticed was the decor of the room. A traditional Japanese layout, perfect for a traditional daughter who would ask for her parent's permission before sneezing. Weird, he thought. He had been expecting her private space to be decorated more fittingly to her real personality rather than the fake one she used around the school, but maybe tricking the school population wasn't the only reason for her facade.

Still, he didn't have much issue in ignoring that particular puzzle while his gaze fell onto the amazing figure of Akeno, her spectacular figure hugged tightly by a lacy black nightie. She looked innocent in her sleep, but Issei had observed her enough to know that it was just an illusion. She was a true sadist that enjoyed both physical and mental torture, though living amongst the students didn't provide her with many opportunities to indulge other than schoolyard torture. Though, Issei's research showed that she was enthusiastic in using stray devil hunts to discharge her particular desires. The few bodies Issei had examined had been littered with signs of prolonged torture.

"Such an interesting challenge you are, Akeno-chan," Issei murmured in enthusiasm. "Just a few days more," he added, trying to reign his dragonic instincts, shouting him to start the process now, but it wasn't hard to suppress them, not with the experience he had on that. Compared to the years he spent on his plan, waiting a few more days until he could break her to rebuild her as a submissive doll was nothing.

The only question was whether to break her first, or after Rias. Both options had their merits. As Rias' queen, Akeno was in prime position to assist Rias to maintain her balance through Issei's manipulations. And while Akeno amusedly complied with his earlier trick today, it was obvious that she only did it as a prank. Anything more serious, she would have interjected, breaking the ploy.

But there was also a certain poetic justice in leaving her unbroken, but watching as her king slowly lost herself in the arms of her new pawn. Breaking Akeno with the help of Rias would be particularly amusing.

Regardless, there was no harm starting it today, he decided. Even if he prioritized Rias over Akeno, there was no harm in getting some head-start. Not to mention it would be e a good excuse to test his new magical abilities, expanded thanks to his devil body. He needed some practice if he didn't want to accidentally destroy a building or three.

With that in mind, he closed his eyes, trying to bring forth the whole concept his sacred gear was built upon.

Doubling.

He couldn't help but think about the closed-mindlessness of the previous wielders, treating their abilities as nothing more than a simple power battery. And as a result, despite the famed potential as a God Killer, no wielder actually managed to achieve something worthwhile. Yes, they did destroy a lot of towns, few cities, and the occasional army, but looking back, no wielder actually managed to do so something worthwhile with their power. And none of them managed to actually kill a god, their straightforward approach to combat easily countered by beings that had seen innumerable forms of combat.

Issei was different. Forced by his mundane background, weak body, and the constant danger he faced, he had been forced to think outside of the box. And in his struggle, he discovered that Doubling, the very concept his sacred gear was built upon, was much more flexible than any of the previous wielders had suspected.

For them, it was nothing more than a tool to increase their physical power, or impact of their magical attacks. However, during his years on the run, Issei had learned how to use that concept to manipulate everything around him, changing the battlefield, manipulating his enemies, even enhancing his occasional allies. He even used to change people's mind. Admittedly, it didn't work smoothly when he tried to manipulate something as fleeting as thoughts. It was hard to use in combat situations due to the target's magical resistance, flaring to the maximum under stress, blunting the effect.

And until now, there had been limited applications for non-combat purposes as well. He hadn't been able to use that without materializing his sacred gear to the physical plane, which made impossible use it for mental purposes unless he was out of their sight.

He closed his eyes, trying to reach the core of his power while suppressing its ability to materialize. Something that would have been impossible without the devil pieces inside him, thoroughly enhanced by dragonic power, acting as an alternative conduit. Even with that, pulling more than a sliver of power was impossible.

But a sliver was more than enough for his purposes…

"Success," he gasped excitedly when he felt the rush from familiar energy filling his veins without the accompanying weight around his wrist. Then, he remembered where he was, and opened his eyes in panic, afraid he had woken up Akeno. The scene that met his gaze validated his alarm. Akeno was shuffling in her place, like she was about to wake up.

"Double," he murmured, more reflexively than anything. The spell, unshaped, was halfway leaving his control when he realized that his mistake. Strengthening himself would barely help him in the situation. In a last-ditch effort, he focused on his spell, trying to link the concept of doubling to the ephemeral concept of Akeno's sleepiness.

Then he held his breath, waiting. Akeno continued shuffling, making him think that he was about to fail. He started to form an invisibility spell, hoping to hide from her gaze, when he noticed Akeno's movements had ceased, and she was back to sleep once more.

He was aware that he was very lucky. Speaking had been a mistake, though not as big as trying to use his sacred gear in a hurry. Casting a regular sleep spell would have been much better, but with his dragonic power already in his hand, his instincts were quicker than his reasoning. Luckily, it somehow worked, saving him from a total disaster.

He turned his focus back to Akeno with a relaxed sigh, who was hugging a pillow tightly against her chest, her amazing breasts trying to spill from her negligee. Even while sleeping, she was really sexy. "Perfect," Issei murmured, feeling safe enough to speak now that Akeno was under the throes of magically enhanced sleep, a prideful smile on his lip, enjoying his success of using his Sacred Gear to fuel his spell without a physical manifestation to fuel a relatively complicated spell. That had so many possibilities…

And no time like the present to test them, especially with such a convenient testing dummy.

Once again he gathered his dragonic power. The target still the same, so was the spell, but the objective was different. This time, her arousal was on the crosshair.

Akeno started shuffling once more, but this time, it brought satisfaction rather than panic. Since Issei was sure that the spell to keep her asleep would hold, he had no complications about leaning back, enjoying the way her negligee ridden up, revealing her smooth thighs, plump enough to tempt him to take a quick bite, or better, deign the surface with a stiff spank.

Much to his disappointment, such a physical involvement was not an option, but luckily, it wasn't the only way Issei could mess with her further. He cast several more spells on her in rapid succession, most of them trying to stroke her arousal further, some to enhance the pleasure she would feel from her own touch, while a few of them slated to make sure she stayed asleep. Then. Issei leaned back, wanting to enjoy the show that was about to start…

The results were lackluster at first, causing her to turn in her bed like she was uncomfortable. But Issei knew better, so kept his position. Soon, Akeno pushed the cover, which was barely covering her body in any case, with an errant kick, providing Issei with the endless expanse of her sinfully delicious legs. The pillow that she was holding against her chest was the next one to go, sent to the floor with a negligent push as she started to warm up.

Issei was very familiar with the signs of arousal, which was increasing every time she twisted and turned, her skin rubbing against the linens of the bed, the sensations enhanced by the spells. After a while, her hands joined the fray, landing on her cleavage, searching for a zipper that didn't exist to reduce the heat. But in their unsuccessful search, they ended up caressing the soft skin of her breasts quite a bit, enhancing her arousal even more, enough to force a gasp through her ruby lips.

But it was just a bite of appetizer in a true feast, Issei realized soon after when she started to search more pleasure. Her hands slid lower a bit, which easily pushed the chest section of her nightwear down, giving Issei a view of her spectacular breasts. Issei could feel his mouth watering at the sight, and his pants getting tighter. Soon, her fingers found her nipples, caressing them softly, forcing beautiful gasps off her lips.

He felt disappointed for a moment when one of her hands slid away, but it left its place to excitement when her hands landed on her legs, slowly dragging down her negligee up, teasing even in her sleep. Soon, it was high enough to reveal a very interesting secret. Apparently, Akeno preferred to sleep without panties.

He shifted the position of his chair a bit, trying to get a better view of the more interesting part of the show, just in time to see her fingers clamp around her clit, every repeat bringing another dash of pleasure, her moans getting louder and louder. Her other hand sank into the supple flesh of her breasts in an effort to enhance her pleasure further.

There was a limit to Issei's patience, and it was coming very quickly. He decided to take a few precautions to prevent a disaster first, casting an alarm spell to alert him if someone comes near. The second thing he focused on was his pants, pushing them down to reveal his shaft. It had been getting very uncomfortable in them. And since it was out, there was no harm to wrap his fingers around it for a couple of pumps just to relieve some of the temptations he was feeling.

Predictably, it didn't really help, especially when her legs widened open to give him a perfect view, and the way two of her fingers slid inside with a corresponding increase in her moans made the situation even more tempting. Issei wished that she was awake, which would make the situation even better, but unfortunately, it was too early to push to the things to such a level, and he didn't want to do anything more in her unconscious state. It wouldn't have been fun.

With a disappointed sigh, he pulled his pants back on and left the room, leaving Akeno alone in her unconscious masturbation, trying to console himself with the success of his experimentation.

A slight concern about doing a bit much during his evening visit had passed Issei's mind as he took a seat on the breakfast table, which he shared with Rias and Akeno, the latter with a mussed hair and slouched shoulders, clearly short on sleep. Either his spells were rather damaging on her sleep quality, or she had woken up as the effects of the sleep portion disappeared before the arousal part, and found herself battling with raging arousal for no reason.

"Did you have a good night's sleep, Akeno-chan," Rias said, clearly concerned. Akeno just shrugged, saying nothing. "Maybe you should skip the first two classes to get some sleep."

"You know how President gets when we skip class, Buchou," Akeno murmured, her eyes on the table, looking exhausted enough to make Issei feel a speck of guilt. Not in an amount to really change his mind about anything, of course, but enough that he took a couple of from the number of spanks he would make her suffer when he finally took the full control of Rias' peerage.

"Don't worry about her, Akeno-chan. I'll talk to her, you just go and catch a couple hours of sleep."

"Thanks, Buchou," Akeno murmured, then turned to him. "See you around Issei-kun," she added, and then left the room, too exhausted to add her trademarked swing to her hips.

"So, Rias-san-" Issei started, only to be stopped by a glare from Issei. "Sorry, Buchou," he corrected with a fake apology. "Is there anything else I need to be careful around the school."

"Just try not to anger Sona-chan," Rias said. "She will be extra-strict on you now that you're a part of my peerage, and it's best if we don't have any reason for conflict."

"Why, are you guys enemies or something?" Issei said, trying to look concerned.

Rias waved off his concern with an amused smirk. "No, we're firm allies, but sometimes Sona could get a bit strict, and it's best if we don't give her any excuse."

"I see," Issei said, focusing on his breakfast, other than occasional appreciative glances he sent towards Rias' chest, lingering just enough to be caught by her, causing her to blush. He had no doubt that, if it wasn't for their earlier encounter, she would doubtlessly enjoy his focus.

He kept silent until he finished his breakfast. "So, Buchou, are we going to have another training session for my sacred gear before the class?"

"Another session?" Rias suddenly stammered, making Issei struggle to keep his smirk hidden. For a supposed naturist, she was having too much trouble showing her body. The loss of control must have affected her even worse than Issei had first thought. "Isn't it a bit early for that."

"If you think so," Issei said with an unconcerned voice. "It's not like we're in a hurry to increase my power. I have no problem hiding under the wards for a while to avoid those fallen angels," he commented, making an obscure reference to Rias' upcoming engagement, one that he was supposed to be unaware of.

"Maybe a quick session is not a bad idea," Rias said.

Excellent, Issei thought as he stood up, curious how far he would be able to push his so-called master this time…

Author notes: Another session with his sexy, redheaded king... Maybe he could convince her for a more hands-on experience...
