Issei couldn't help but feel a bit of a loss as he left his room, leaving Asia alone, collapsed on the bed, reeling from the effects of his skillful tongue, naked as the day she was born. It might be her sense of abandonment forcing her to lean on the first one that supported her, or it might be the devil transformation that might be transforming her mentality. Issei was glad for it in any case.

The first few days of his life as a devil had gone better than he expected. Rias, his supposed king, was much easier to manipulate than he had assumed, making his attempts of subverting her rule fun. He still had to be careful of course, as Rias was hardly the most dangerous Gremory. No, that honor went to his brother who had abandoned his family name to take the title of Lucifer, famous as the strongest devil. As much as Issei wanted to test himself against him, he knew it was too early for something like that. Luckily, there were a lot of things for him to dally while he got stronger, two of them he had already acquainted in detail.

And with Rias and Asia have already taken the first real steps under his dominion, it was time for Akeno to join the fray. He needed to visit the training arena where Akeno was waiting for him, but he decided to take a small detour to the armory. There, he picked a couple of armor pieces, a stylish chainmail, and an imposing gauntlet to his left hand that wouldn't look too bad with his Boosted Gear. It was more about the style and to convey the seriousness of the situation to Akeno rather than their protection value, as his skin was much harder than any armor that they had laying around.

After completing his new gear, he was at the underground training area underneath the club. "You're late, Issei-kun," Akeno said in a tone that might have been mistaken for calm, if it wasn't for his enhanced dragonic senses catching her annoyance. Still, he was happy to hear that, as it would make it even more satisfying when he finally pushed her down to take her.

The way she was dressed was even better than the promise of satisfaction. She was wearing a modified shrine maiden outfit that hugged her body perfectly, displaying every single curve she had without shame, with a cleavage deep enough to reveal the color of her bra, which was purple. Also, her outfit was short enough that her every movement carried to the risk of flashing him. Even better was the seductive expression on her face, enough to stir his desire, her hidden annoyance just enhancing it more.

Her careful selection of attire was clearly had ulterior motives, once again trying to quicken the awakening of his devil powers through the sin of lust despite its potential to harm him if he had been as weak as he was playing to be.

"Sorry, Akeno-chan," he said with an insincere tone, something Akeno caught easily if the sudden tightening of her smile was any indicator. "I had to help Asia-chan before leaving. It would have been rude to cut my help halfway. She needs to acclimate herself to the life of a devil."

"Are you trying to make me jealous, Issei-kun," Akeno countered, trying to sound teasing, but that was only paper-thin, hiding the heat of her anger underneath. Issei had a feeling that it was more about him being late than actually anything about Asia. Still, he enjoyed the way Akeno displayed her cleavage as she teased him.

"I don't know what you mean, Akeno-chan. I'm helping her just the way you and Buchou had helped me? Is it somehow unusual?" Issei answered with a smirk, letting his eyes drag over her body to remind her that she had been forced to serve as a common stripper at her king's request just to speed up the development of his devil powers, poking at her pride unashamedly.

Akeno chose not to answer, instead of waving her hand, making a bunch of targets appear on her field of view. "Today we're going to work on your magic skills," she explained, her calm exterior trembling for a moment, unhappy with his reminders. "First we're going to work on materializing mana, then we're going to move onto target practice." Then, she smirked in a way that showed she might have certain ideas for the training. "However, just to make sure you're paying attention to the training, I'm going to give a small shock to you every time you miss a shot," she continued, lightning crackling between her fingers.

"Really, Akeno-chan? Wouldn't it hurt?" Issei said, but this time, he wasn't bothering to maintain his idiot persona, aware that their little game was about to come to an end. Under the circumstances, it was better to keep Akeno focused on him rather than her keeping a calm mind and discussing things with Rias. He still needed some time before Rias' situation could be revealed to the rest of her peerage.

Akeno giggled. It wasn't a cute, playful giggle. Instead, it was one that hinted that her reputation as the Sadist Queen wasn't an empty title. "Maybe a bit, but I'm sure a strong man like you can handle without an issue, Issei-kun?"

"Maybe I can," Issei answered. "But that doesn't mean that I will," he added, but continued before she could cut in, "unless there's something really interesting on the table, of course."

"Of course," Akeno answered with a smirk, amused at his presumption. From her gaze, Issei could read that she was already convinced of his failure. After all, he was just a new devil, far above the situation. "What do you have in mind, Issei-kun?"

"We should go for something simple, how about you lose a piece of clothing whenever I hit a target."

Akeno frowned a bit at his offer, aware of his high likelihood of accuracy. After all, targets weren't exactly small. Then, her eyes grew as she subtly waved her hand in a way that she thought as hidden. With his magical perception, Issei could see that she had established a repelling field in front of each target, one that would deflect his spells, preventing them from hitting the target. "Not a bad idea, Issei-kun, but a target is too big. How about we limit it to the bullseye?"

"Only if I got to add another condition," Issei answered. Akeno nodded, and he continued. "Anything that gets removed stays that way until the end of the training session, including the sparring."

"You want to spar with little poor naked Akeno-chan, then," she answered with a mock despondence as she leaned forward and pushed her arms together, enhancing her cleavage further. "What did I deserve to gain such a merciless student, trying to hurt his teacher in the first lesson?"

"Don't worry Akeno-chan, I'll make sure that you enjoy it," Issei said confidently with a wink, making Akeno even angrier. But it was better for him, angrier she was, the longer she would last.

With one final nod, she launched a small tutorial on how to externalize his magical prowess, and she even thought him a small lightning attack. Issei nodded in hidden appreciation on her trick, as lightning was not only hard to control, making it a poor selection for target practice, but also it would have been affected by her lightning-natured repelling fields excessively, making it impossible for it to meet with the target.

Too bad for her that Issei was already capable of magic.

After around five minutes of training, Akeno decided to cut it short. "That's enough theory, Issei-kun," Akeno said with a giggle. "Why don't you try to conjure a ball of mana?"

Issei decided to struggle a bit at first, mostly to make her even more confident about the bet before he pulled the rug underneath her. The first ball of mana he conjured was a small, pitiful thing, barely able to stay alive under its own power. "Come on, Issei-kun, try a bit. You know what they say about guys with small mana," she said mockingly.

"How about if you give me a little incentive like you did while trying to help me conjure my sacred gear," Issei said.

"Such a naughty boy," Akeno gasped excessively as she brought her arm on her lips, her other hand on her leg. "What do you have in mind?"

Issei said nothing, just reached forward and grabbed her breast mercilessly, his fingers sinking into her flesh easily. Her eyes flashed in anger at his presumption, her hand sparkling with lightning, but she managed to hold herself back, still trying to play a role.

Just as Akeno opened her mouth, ready to remove his hand, he let his magic free, and a crimson ball of energy, with occasional bolts of lightning dancing on the surface, appeared, floating above his palm, too dense to belong a novice. Under any other situation, such a display would have revealed his play as the human unaware of the supernatural, but luckily, Boosted Gear and the boost from his sin of lust was enough to explain the phenomenon. Even if Akeno felt suspicious, it wouldn't really matter in a few days.

"How about this one, Akeno-chan?" he asked with a smirk even as he kept squeezing her breasts repeatedly. When her eyes got stuck on his proto-spell, he decided to use her distraction to a better benefit, and slipped his hand into her cleavage, mauling her tits over her bra, its thin fabric barely isolating her skin from his.

"Not bad, Issei-kun," Akeno answered, still fascinated by the way crimson lightning was dancing threateningly on its surface. Issei used the opportunity to push his luck more, and pulled her bra to the side, and started massaging her naked tit skillfully.

Only after a gasp escaped her mouth Akeno realized the liberties he was taking. "That's enough, Issei-kun," she said as she took a step back, giving him a glimpse of her naked breast before quickly fixing it. "Let's see whether you'll be able to hit your target," she said quickly, occupied by her lapse of attention.

Issei smirked at the way she was cheating, not allowing him to master the lightning spell before trying to hit the targets. He decided to play along, and cast his first spell badly, letting it fizzle out of existence halfway. "Too bad, Issei-kun," Akeno said as she blasted him with a bolt of lightning.

"Ouch, careful," Issei said, making a show of being hurt. Akeno wasn't holding back much, the amount she had used would have left a new devil twitching on the floor.

"Come on, Issei-kun," Akeno said as she put her hand on his shoulder flirtatiously. "You're the holder of the boosted gear, don't tell me you can't handle a weak bolt of lightning." Issei just smirked before casting the spell once more, this time reaching the target, but bounced to the side by Akeno's deflection field. Akeno hit him with another lightning bolt, several times stronger than the previous one.

"You're really pushing your luck, Akeno-chan," Issei said as he smiled at her darkly. If the previous one would have damaged a new devil, this one would have killed the said devil instantly.

"Surely not, Issei-kun," Akeno said with a fake smile, but he could see hints of suspicion underneath. His lack of reaction to her attack was simply too mild, especially considering he didn't have the boosted gear out. Luckily, it was just a groundless suspicion for the moment.

Issei decided to give her a more immediate problem. He conjured the lightning once more, this time several times stronger than before, and sent it forward, creating a crater in the middle of the target. "Bullseye," he said as he took a step to Akeno, and put his hand on her shrine maiden outfit.

"What are you doing, Issei-kun?" Akeno murmured.

"Getting the fruits of my victory," Issei said.

Akeno looked annoyed at his presumption, but she was under orders, so she had to swallow her dissatisfaction. "Don't you want to watch me undress slowly, Issei-kun," she murmured playfully, but Issei could see that it was an attempt to maintain control.

"Nope," Issei answered as he tugged her outfit, ripping it violently, leaving her in her underwear.

"Such a naughty boy," Akeno giggled, trying to hide her discomfort, more due to her sudden loss of control than the fact that she was in her underwear. After all, it wasn't the first time she was revealing her delicious curves to his sight.

Issei cast another spell, missing once again. "You need to work on your aim," Akeno said as she raised her hand, her smile displaying her full sadism without bothering to hide. Before she could blast, Issei conjured his boosted gear, not because he needed its assistance to resist her overpowered attack, but to have an excuse about his lack of wounds.

Akeno giggled as she blasted him with an extended lightning bolt, the intensity increasing in each second. It was far from her full power, but still, considering she was already a high-class devil, it didn't mean a lot. Issei was glad to have his power, because Akeno was as crazy as she was sexy. Dealing with her without his powers would have been a nightmare.

When she stopped finally stopped, she saw his untouched visage. "How?" she murmured, shocked. Issei just waved his gauntleted hand in response. "That's cheating," she murmured. Issei just smirked before conjuring another lightning spell, once again hitting his target.

This time, before he could take a step to her, she quickly removed one of her sandals. "A piece of clothing, just as promised," she said, her smile smug.

Issei let her enjoy her momentarily victory before casting another spell, destroying yet another target. Akeno removed her other sandal. With a smirk, Issei hit two targets in a row. "It's easier than I would have assumed," he said smugly as he closed in the distance once more, one hand on her panties, the other on her bra, both falling on the floor in pieces after he pulled them violently, revealing her naked visage for his sight.

"Do you want to continue with the target practice, Akeno-chan," Issei said smugly as he examined her body without shame, his bulge visible. "Though, we might need to strike a new bargain considering your state of dress."

"No, we can move to spar," Akeno said, not bothering to hide her visage as she walked toward the center of the stage, her beautiful assets jiggling with each angry step. "We need to make sure that you can hold yourself in a fight."

"Of course," Issei said as he walked closer, the Boosted Gear still prominently displayed on his arm. Akeno looked at it with dissatisfaction, but not worry, clearly assuming that her Queen amplifications would be sufficient to dominate him.

It was a dangerous assumption.

"Are you sure you want to do this?" Akeno said mockingly, more to goad him to act than any concern about his wellbeing. "There's no shame in admitting that you're weaker than a poor little girl like me," she added, trying to goad his pride, and through the way she jiggled her tits, lust as well, making sure he wouldn't surrender easily.

"Nope, I'm ready to go," Issei said, taking a step forward and raised his arm. "But how about we make it a bit more interesting," he added.

"I'm insulted that you don't find a spar with this poor girl interesting enough," Akeno said with a giggle as she pointed at her naked body, her every curve sculpted to perfection to give a sense of feminine allure, begging Issei to push forward and take her down.

"You're beautiful, Akeno-chan," Issei said. "But I'm thinking that stopping after pinning you on the floor, helpless, would have been such a pity. So, I'm thinking that we continue no matter what until someone admits defeat." He smirked as he let his eyes focus on the treasure between her legs. "No matter what," he repeated.

"Oh, ambitious," Akeno laughed derisively, fully expecting to win and insulted by him thinking that he had a chance of victory."But if we're going to do that, I want something better. The winner wins one night, from dawn till dusk, with no restriction on the requests."

"If you are willing to be my plaything for a full evening, who was I to disagree," Issei countered, gesturing her to start.

Author notes: Akeno learns that a battle under misinformation might be a dangerous affair...

Sorry about that but it had been a while since I had last updated this little gem. I finally come around to update this story, which is quite fun to write. Hopefully, I will be updating this more often.

As usual, my original works are in P/atreon / dirk_grey.
