When Issei left the student council room, he was feeling like a saint. Not only he had resolved the issue between his peerage and an allied peerage, he even helped Sona to process such a personal sense of inadequacy about her small breasts.

He was such a nice devil…

He had just reached the building of the occult club when he saw Asia, still wearing her nun outfit, only with the crosses removed. "Issei-kun," she stammered immediately, with a blush spreading on her face, unable to make eye contact after their last interaction, where Issei had been eating her enthusiastically.

"Where are you going, Asia-chan?" Issei asked as he walked closer, already intending to drag Asia away from whatever she was planning to do. Her plans couldn't be as fun as his plans for her, after all.

"T-to the library," she stammered, her blush intensifying as she did so. "I don't have anything to do, so I was going to study."

"That would not do," Issei said with a shook of his head.

"Why?" Asia asked panickedly. "Rias sempai said that I could use the library whenever I need."

"It's not about you not being allowed to use the library," Issei said with a chuckle, bobbing her nose as he did so. "It's about wasting such a beautiful day," he added, pointing outside, with the sun shining. While being a devil meant a certain amount of weakness to the sun, it wasn't exactly debilitating, just slightly annoying for a moment, like stepping outside from a dark room.

"But, I can't go anywhere," Asia said. "Fallen angels-"

"Will not be a problem as long as I'm with you," Issei cut in determinedly. "Now, move," he said even as he grabbed her hand. "We have a date to go."

"A date," Asia gasped in shock, but that didn't prevent her from speeding up, even trying to drag Issei forward. "Like eating in a restaurant, walk in a park, that kind of thing."

"No," Issei said, but seeing her expression fall, he aborted his plans to mess with her. Teasing her like that felt too much like kicking an innocent puppy, which was too much even for him. "I was thinking more in line of shopping and amusement park," he added.

"Really!" she said, her enthusiasm back with interest as she started dragging Issei once more. "We're going to an amusement park!"

"Yes, as soon as we stop by a shopping center and buy you some new clothes. You can't walk around as a nun," he said, mostly for himself. As much as teasing her while she still wore the uniform of her previous job was fun, he wasn't really obsessed with the church and their authority to need a constant reminder of Asia's previous occupation. She was plenty fun in a sexy, innocent way without turning her into a weird object of fetish.

"If you say so," Asia said, not exactly torn up with the need to get new clothes and abandon her garb, her enthusiasm about the amusement park triumphing over her habits handily. Issei didn't bother informing Rias about his destination, or even update her about the results of his talk with Sona. After their last 'special' talk, his new role was pretty much established in her mind, and he just needed to push it until it became the new dynamic, before Rias stopped needing him. He wasn't concerned with what Rias might do, but her brother was a different issue altogether. If possible, he didn't want to be facing the current Lucifer.

At least, not until he could get a better handle of his new powers.

The walk toward the mall had been rather entertaining, with Asia being amused by even the smallest things, from the snacks they bought from the street vendors to the sight of children playing in the parks. Though, the real enjoyment she was deriving was holding his hand as they arrived at the mall. Issei directed them directly to the most expensive shop, one that had a large number of branded clothes.

Another perk of being a part of the peerage of an heiress, infinite spending money.

"Is this okay to spend that much, Issei-kun?" Asia asked hesitantly as she examined the nearest price tag, with a rather lengthy line of zeroes.

"Don't worry about it, the Gremory family is filthy rich," Issei said, dismissing her concerns immediately. He didn't want her having problems about spending money, after all, it was just money, something Rias didn't care even one bit, though even if she did, Issei wasn't sure how much he would have been affected by it.

"If you say so," Asia accepted readily. Even with the subtle manipulation embedded in the evil pieces, Asia wasn't really loyal to Rias, after all, not after Issei made a bloody show of saving her, bargaining with Rias to extend her protection on Asia. She liked Rias, of course, as she was too nice to feel otherwise, but Issei was sure that if the push came to shove, it would be his orders that would be listened to. So, they started shopping. Issei made her try a few tops and a couple of modest skirts at first, more to make her get used to posing for him in the dressing area for the females, which, thankfully was completely deserted other than the occasional saleswoman, ensuring that Asia's shyness wasn't a big problem.

However, her composure didn't last long when Issei passed her a rather tiny lacy tank top, pure white, with a cleavage deep enough to show off her modest breasts without being obscene, something he had picked from the lingerie section. "Isn't it a bit much, Issei-kun," she asked hesitantly.

"Your call," Issei answered. "But I think it'll look nice on you, and it's not like you'll be wearing it outside. Just wearing it around the club would be enough."

"Really," Asia answered, her blush suggesting that she had understood what he had been driving toward. She might be innocent, but she was not stupid, and what he was meant after their interesting bedroom games wasn't exactly a difficult mystery to solve. Then, her face scrunched a bit. "But I can't come out wearing it," she added.

"Don't worry about it," Issei said even as he put his hand on the small of her back, slipping inside the dressing cabin with her, closing the door behind, with several more items already arranged on his arm for her to prepare.

"Close your eyes," Asia murmured shyly but excitedly.

"As you wish, my sweet nun," Issei answered with a chuckle, amused at her sudden shyness after the morning, but still, he closed his eyes. However, since he was a devil, he still watched her from his cracked eyelids, watching her as she removed her top, revealing a bulky bra underneath, making the range of lacy and transparent underthings Issei was holding more of a necessity than a naughty extra.

She did turn her back, but with a mirrored wall reflecting her sweet sight, she didn't manage to hide anything as she removed her bra, revealing her perky tits for his attention —not that she was exactly trying her best in the first place. Then, she pulled on the white camisole, looking sweet enough to eat. "Done," she said asking him to open his eyes. He let his gaze drag down her beautiful body, enjoying the sight for an extended period while her blush continued to get thicker. "How does it look?" she asked hesitantly, her self-confidence readily shattering.

"Delicious enough to eat," Issei answered as he took a step forward, capturing her lips with a heated kiss, enjoying her absolute passivity. Though, being passive didn't mean she wasn't enjoying the kiss, moaning in satisfaction.

Though, her moans of pleasure were soon interrupted by a gasp of shock, when Issei's hands slipped under her skirt to pull down her current panties, leaving her naked under her skirt, which was tall enough to cover her knees. "Issei-kun," she gasped, scandalized, but that didn't prevent her from leaning further, rubbing against his body, no doubt remembering the pleasure of the morning.

"We need to pick a fitting piece," Issei said even as he sat on the only available seat in the dressing room, but he wasn't a hooligan enough to keep Asia standing while he was sitting down, so he pulled her on his knee, before pointing at the pile of lingerie he had picked. "Why don't you pick one."

Asia was shy enough that just the act of picking lingerie next to him was enough to drown her brain with a shy shock. She was clearly finding it challenging enough to do something like picking up lingerie —especially since Issei made sure to keep the selection rather risque— but doing so while sitting on his lap, with the noticeable absence of her knickers, was much more difficult.

"Why don't you try this on," Issei suggested as he grabbed one of the white lacy ones, on the small side but that would fit well with her camisole. "I'm sure it would look amazing on you," he said as he passed them to her.

However, he then wrapped his arm around her waist, preventing her from standing up. "Right now?" she asked shyly.

"Yes, unless you would prefer to walk around without one," Issei suggested, which earned a panicked yelp from her.

"Madam, is everything okay," called one of the saleswomen.

"Y-yeah," Asia stammered. "I just hit my toe," she managed to say after a brief break, sending her away.

"So, which one you prefer," Issei whispered throatily into her ear. She didn't say anything, but raised one of her legs to slip the panties on, while trying not to make it a show, though only partially successful as her skirt ridden up. Issei let her go when she finally managed to pull them on, her bashfulness clear on her face as she stood up. "Excellent, so why don't you get rid of that skirt so that we can see how well it fits you," he suggested even as he stood up, waiting for her to do so.

It was a request enough to trigger her conservative approach, but maybe it was her newfound bravery as a devil, or maybe it was the effects of their morning adventure, but that didn't stall her more than a second as she grabbed the zipper of her skirt, letting the bulky stuff pool on the ground.

"Delicious," Issei said as he put his finger on her silky legs, trailing upward. "White looks amazing on you," he added, even as he drank the breathtaking view, with only a set of lacy underwear to cover her modest yet perky proportions, stirring his shaft with the undercurrents of desire. The fact that he had already had some fun with Sona in less than an hour —and some more moments before that with Rias— didn't exactly help him relax. His dragonic nature, combined with his recent devilish additions, was pushing his desire overdrive. "Now, why don't you test whether you like the texture of your new underwear?"

"I don't know," Asia murmured shyly, but that didn't prevent her hands from starting to caress her breasts, her innocence slain by the memory of her pleasure and her increasing arousal, so much that Issei didn't need to rely on his boosting to actually enhance her arousal. Her hands started to wander over her body, her gaze jumping between the mirror and Issei's face, her blue eyes expressive, shivering as her hands danced on her soft skin. Issei smiled in approval as she started palming her globes, just large enough to fill her small hands.

Soon, her eyes were closed as she focused on the sensation. Issei stood up, breathing on her neck, making her visibly shiver. Then, she managed to surprise him by letting one of her hands travel down, passing over her stomach to arrive at her core.

The sight of Asia caressing her soft womanhood over the deficient cover of her lacy panties was the last step for Issei, breaking his flimsy self-control. He grabbed her ass, which was barely covered by the deficient back end of her panties, and started caressing slowly…

Asia's eyes popped up as she felt his hands on her body, their eyes meeting on the reflection. Her mouth opened to let out a guttural moan, barely suppressed enough to a point that wouldn't alert the saleswoman. Even then, considering her shyness, it was a wondrous achievement.

"Hmm," Issei murmured even as he quickly pulled some new pieces from the pile he had chosen, this time a pink set, bright enough to be cute if it wasn't for their rather deficient usage of fabric, significantly skimpier than what she was currently wearing. "Why don't you try those on as well."

"Right now?" Asia murmured, but despite that, it didn't take long for her to unhook her bra and let it fell on the floor, her arousal more than enough to suppress her shyness. And it wasn't like it was the first time Issei was seeing her naked.

"Let me help," he said as stood up, letting his hands find her supple hips once more before pushing her panties down again, this time without her skirt to hide the delicious view of her wetness. She moaned as he dragged it down slowly, enjoying the sight of her ass as he bent down. "Lift your foot," he ordered, removing per panties, then putting the other on before dragging them up to their place, even slower than the previous attempt. She was gasping in pleasure, nearing close to orgasm even as she put her bra on, small enough not to cover her areolas successfully. Even her nipples were barely in, looking ready to pop out at the slightest mistake.

Dressed in the naughty pink underwear, Asia looked delicious, and her arousal was getting more and more with each passing second. Issei could have pushed her for more easily in the dressing room, but ultimately, he decided otherwise.

Teasing her during her promised amusement park visit would be much more interesting if she was feeling the pangs of unmet arousal during the trip, maybe to the point of taking some initiative… But even if she didn't, it promised to be an interesting trip, Issei decided even as he passed her a miniskirt and a cute looking top with spaghetti straps, watching as she put them on, too shy to insist for him to finish what he started…
