Story: HHL HS DxD

Given the sheer power that both Rias and Sona were capable of unleashing, it wasn't often that they felt the need to take a stealthy approach. Surely such a situation must merit some form of intense imminent danger? No? Then perhaps intense personal embarrassment?

"Oh darn, I've spilled cream alllll over my thighs."

"Hold on, I'll lick it off."

That's a great big yes right there. Sure, Rias may have been more willing to indulge in certain things when it came to her sole pawn. But that didn’t mean she wanted to get sucked into some kind of perverted game for the enjoyment of an unknown actor. Not to mention Sona, who had quite the reputation as a serious no-nonsense type to uphold.

"It seems to be influencing common sense," Rias noted. Sona nodded. "Fascinating. Nobody seems to notice that anything is amiss."

"You have that bad habit of using 'fascinating' as a synonym for 'terrifying'," Sona said. "It might be a good idea if we didn't stand so close to one another. We might start doing perverted things to one another without noticing."

“I don’t think so, did you notice, people only join into these perverted nonsense if someone takes note of them.” Rias said, chewing her lower lip in thought. “Perhaps it is like.. a magical plague.. and if you get infected fully you start spreading it unconsciously..?”

"You remember that I was almost drawn into this as well, don't you?" Sona hissed. Then blushed as she remembered teetering on the edge there. "Still, that's as good a theory as any. I think we should try to find that white rabbit, she seems to know something."

As such, they crept through the corridors trying to stay out of everyone's way. Not exactly easy when you're both in the top five hottest girls on campus list, but made a good deal easier because of the magic they had at their disposal. Between the two of them, it wasn't too much hassle to cast a simple distraction spell that would keep most people from noticing them.

"Rias. Sona. Why are you sneaking around school?"

Most people not including, for example, magically sensitive Devils. In this instance, Rias was a bit relieved to hear Koneko's familiar voice. What was less reassuring was finding her in a skimpy catgirl outfit while reclining on a windowsill.

It should be noted that this was rather redundant given she was in fact a catgirl.

Rias initially made to reach out to the girl out of concern, but Sona stepped in front of her and shot her a look of both understanding and reassurance.

"We're looking for a girl in a white bunnysuit," Sona said. "We think she might be causing mischief around the school."

"Mischief?" Koneko said in a strangely lewd way. "What sort of... <i>mischief</i>. Does it involve <i>Issei</i>."

Rias dearly and sincerely wished she hadn't humped the air when saying it the second time. And definitely not when she'd said Issei's name.

"Possibly," Rias said. "Have you seen her anywhere?"

Koneko tilted her head and thought it over for a moment. "Everyone must be somewhere," she said. "But then again, does that mean someone must be anywhere?"

“Erhhh..” Rias said, clearly not having anticipated Koneko of all people to start talking in riddles.

“If you want, I can lead the way.” The silver haired girl said, face neutral and yet somehow giving off a strangely energetic aura. “Some cum the long way, others cum the hard. But me, I prefer the short cut. It prevents you from cumming and going."

“Koneko.. Did you meet anyone strange today..?” Rias asked, resisting the urge to turn tail and run for the hills.

"We're all a little strange, aren't we?" Koneko calmly replied. She grabbed the tail from the end of her costume and began to fellate it. "I'm strange. You're strange. Together, we are strangers."

"Okay, I've had it up to here with these Alice in Wonderland references!" Sona said. "Koneko, stop messing around, or I'll hit you with the hose!" No, Rias thought! She might like that in this state! "Also, you make a lousy Cheshire cat because you're not smiling and you're not becoming... invisible..."

It was true enough. Koneko wasn't the sort who would make a good Cheshire Cat, not really. No insane grin, and she wasn't capable of turning invisible. At least, not normally. But as she lay there all catlike on the windowsill, she was starting to vanish. Not so much her body. Just... her clothes. Skimpy though they might be, they were vanishing right before their eyes.

It should be noted that a devil’s magic unlike that of other species was mostly based on desire and will. No matter how ridiculous, as long as the user has enough power and dedication they could pull off almost anything. After all, Issei had managed to create a technique that only destroys clothes and another that lets him talk with breasts.

"What's next?" Rias quipped. "Perhaps we'll encounter a stoned caterpillar? Or, no. How about a young woman covered in sushi lying on a table, with a sign that says 'eat me'. And eating off of her makes you shrink? Or a pair of goofball twins who speak entirely in perverted rhyme?"

"Thanks, but no!" Sona sniffed. "I don't see any reason for us to play along with this perverted retelling of Lewis Caroll's hate boner for Complex Numbers."

"You know that's only one interpretation of -" Rias began.

“I could lead you somewhere fun. Or you could let your need guide your behavior.” Koneko said, tilting her head and continuing to vanish. The twist being that in addition to her smile, her breasts and pussy were also still visible. "As I was saying, I know a shortcut."

"A shortcut?" Rias asked, stepping closer to her disappearing Rook. "What sort of -"

Then she stopped cold. To Sona, that was a little frightening. Seeing Rias suddenly stop in place like that, seeing her shoulders sag, it was quite a warning that whatever lay out that window was quite a sight to behold. Nonetheless, Sona could hardly stay back now, and so she walked forward and -

“Ohhhh, we're painting these girl's breasts red, we're painting these girls' breasts red!” ♬

“Painting the boobies red, painting the boobies red, we dare not stop, or waste a drop!”♬ Voices continued singing from outside and finally Sona turned her head and saw.. well exactly what she was hearing.

A mixed group of students were wandering around the schoolground and whenever they found a girl, would start a conversation. Whatever was exchanged, they couldn’t hear but it seemed to be rather convincing given the trail of confused looking girls with red coloured chests left behind.

"It's official," Sona said. "Today is the worst day of my life."

Then she turned around and saw Koneko's head affectionately rubbing up against Rias' thighs. Rias had adjusted her collar ever so slightly, showing off a touch more of her ridiculous chest than normal, while Koneko's head was moving up and up and up...

“Come on, pet the pussy.” The catgirl all but purred.

"Good kitty..." Rias mumbled, bleary eyed and hand wandering  -

"Oh no! None of that!" Sona snapped, slapping Rias' hand away. "You're not getting out that easily!"

"Whatever do you mean?" Rias asked. "Ah! What happened to my collar?"

"I take back what I said before," Sona said. "It's not just the worst day of my life. It's also the second, third and fourth worst as well! Come on, Rias Gremory! Focus you and I are stronger than this... This perverse influence! We are Sitri and Gremory, and we will not be brought low by something so base! So come with me, and let's inspect those painted red boobies!"

<hr>

The reason Issei had hidden in the lady's room was innocent for once. The reason he had cracked open the stall door he was in, that was purely to watch and make sure he could flee safely and unnoticed. Not even to flee from punishment, or at least not the punishment he would normally get.

But the second he caught sight of those two girls kissing, he couldn't take his eyes off them. It was hot. Super hot. They were both really cute (not as nice as Rias or Akeno, but still!) with big breasts, trim waists and hands wandering underneath each other's skirts revealing both of their underwear to anyone that cared to see.

"You know, it's funny," one of the girls said. "I'd be totally okay with a boy watching us right now."

"Yeah, actually I kind of wish there was a boy watching us. That would be super hot."

It's a trap! It's a clear trap! They were trying to lure him out and - by god, it was working! If only there was some way for him to be certain of his safety. If only he -

Oh yeah, his secret and feared technique that he had personally developed.

Issei closed his eyes and gathered power in his hands. His left hand transformed, gaining crimson scales and a green gem at its centre.

“Pailingual!” He thought and the energy between his palms was released, moving outwards almost like a field of light. Not that anyone without magical awareness would notice anything was happening at all.

“Boobs, tell me the true intention of these two!” He asked in his mind, feeling his thoughts reach out to each of them.

<i>"I am so into this right now,"</i> the girl on the right's breasts said. For you see, this was what this power did. Pailingual, the ability to hear breasts! Capable of bypassing spells that protected from mind reading as it didn't actually influence the mind in the slightest!

An outrageous and rather perverted ability that got banned in official battles because honestly, it is freaking unfair.

Anyway, the one thing he was kind of wishing the girls would do was actually let their breasts out so he could take a quick peek -

<i>"Gotta let 'em out!"</i> both girl's breasts said quite plainly at once. <i>"Give the girls some air."</i>

Huh. That was kind of weird timing. Now the two girls were stripping each other down, and - wow, this was really heating up now. The only way it could get much better would be if one of the girls started kissing the other's navel so he could get a better look at -

<i>"Kiss her tummy!"</i> one girl's breasts screamed excitedly.

<i>"Kiss my tummy!"</i> the others added.

And so, that's what happened. Alright then. So, twice was a pattern, but surely not. Not a chance. Issei gulped. He'd had those thoughts kind of automatically, you know? With his libido, it was kind of inevitable that he would start fantasizing at the slightest stimulation.

The possibility that his lewd fantasies could be affecting them... There was only one way for him to be certain. He had to test it, and only one thing would work for certain!

<i>"I wanna be a harem girl!"</i> both girl's breasts said at once.

Oh no. Oh no! It was just as he was thinking! His fantasies were influencing them. His perverted erotic fantasies were what were somehow making people act this way! This was bad. This was very bad. Now, that might seem like it's counterintuitive. Surely a pervert like Issei would want everyone to be a pervert. Right? Well, no. Not really. Think about it.

If you raise the standards of perversion like this, then what happens to those who were already quite kinky? Their bar would raise as well. He would become like a beacon of perversion, making everyone around him lewder and in turn being influenced by others. A positive feedback loop of lewdness that would surely cover the planet before the year was out.

The outcome: If everyone was a pervert, then nobody would be. That... did not sit well with him.

Which left him in quite the quandary. His mind was already quite a dirty place, and if it was fueling this reality warping and personality affecting whatever it was, then they might already have been doomed from the moment this started. It's a variation of the classic pink elephant problem: Try not to think of a pink elephant. The act of trying to avoid thinking of one will make you imagine a pink elephant right away!

<i>"Let's make a haremgirl club!"</i>

<i>"Let's make a boobs fanclub!"</i>

Aaargh! You see! This was the dilemma he was in right now! He'd had those exact thoughts, and now they were influencing these innocent girls! He had to get out of here. Hang getting caught, he had to find Rias and warn her of his discovery!

Luckily the girls were too caught up in one another to notice him. Probably helped along by him deliberately making them too into each other to pay attention. Not an easy thing for him to manage, but he somehow managed it. Issei opened the door, then ran out - And promptly tripped up over a foot. Before he knew what was happening he was being straddled right out there in the corridor by - by!

<i>"Punish the pervert</i>" Aika's boobs said. <i>"Then set him up with Asia once he's all calmed down... That'll be so hot!"</i>

Somehow it seemed that reaching Rias might be more difficult than he first thought it would!

"Not going to lie," Eve said. "This might be the easiest universe we've conquered yet. It's like you were already teetering on the edge, and just needed a tiny push to fall."

“What exactly are you talking about?” Kiba asked, looking up from where he was holding one of his fangirls in place as she enthusiastically deep-throated him. "Conquest, you say? Whom do you represent?"

“Oh you know the usual, interdimensional conquerors trying to install their own ideology and regime. Get all the unwashed masses hooked on lust and perversion, until they happily start worshipping our asses and tits.” She said, slapping her butt and pushing out her chest as an example. "You know, that old cliche."

"We'll find a way to stop you," Kiba insisted, even as he came right down the slut's throat. The girl right behind that one made a needy sound and pushed against her butt. Clearly, she wanted her turn to suck him off already.

Eve raised a single eyebrow and gazed at the line of half a dozen girls waiting for their chance at orally pleasuring their crush. Really, pretty boys were so easy, even more so when they were secretly rather perverted.

“Ohhhh, we're painting these girl's breasts red, we're painting these girls' breasts red!” ♬

“Painting the boobies red, painting the boobies red, we dare not stop, or waste a drop!”♬

"Music to my ears!" Eve chuckled. "Oh, I've heard of this, the Alice in Wonderland route. What fun, what fun!"

"Alright! Enough of this! Break it up! Stop it with the paint!"

"Eeeeek!"

Eve scowled. Someone interfering with the ongoing fun? How unfortunate. It seemed that someone had enough presence of mind to resist. What a spoilsport!

"My Queen! My Red Queen!" a strange girl in a white rabbit girl outfit yelped, screeching to a halt directly in front of her. "I'm sorry that I'm so frightfully late! However! I have lured Sona Sitri and Rias Gremory out into the open!"

Oh? Was that so? Were those the pair that were getting in her way? Well, Eve could only smirk at that. She'd originally been planning to keep away from anyone too powerful in this universe, but from the way things were progressing... Maybe it was about time for her to make herself <i>known</i>.

1. Issei manages to escape Aika, and reports to Rias.
2. Issei is dragged off by Aika to meet with Asia, who is too innocent to be properly corrupted.
3. Eve openly challenges Rias and Sona to a game of croquet. Perverted croquet.
4. Eve instead decides to keep herself hidden and tries to set Rias against Sona.
5. Where exactly did the reality warping cube end up anyway?
6. Something else
