Story: DxD Cocknosis

The relationship between Rias Gremory and Sona Sitri was one of rivalry. Now. One might expect that, given as one of them is the student council president, this would mean that things are typically made quite difficult for the other one which is in charge of the school's Occult Research Club.

Not really. It wasn't that kind of rivalry. While the two of them would love nothing more than to rub the other's faces in a loss - and you'd better believe that both sides have taken the big L over the years in various contests - they weren't so stupid or as foolish or as spiteful as to escalate their one upmanship attempts to the point where things would become... difficult for their families.

Because that way led to fates much worse than a spanking. As they say: There's always a bigger fish. In this case those bigger fish were mostly siscons. So yeah.

"Well, well Rias. So good of you to come and pay a visit," Sona began, sitting behind her desk and adjusting her glasses. "I hear that you've acquired your first Pawn."

"My only Pawn," Rias corrected. "He took all eight of them at once."

"All eight, you say?" Sona's voice shited down an octave a bit. "My, my. So. Quality over quantity. Not a bad choice, I have to admit. But still! Wouldn't it be better to strike a more even balance between the two?"

“Oh, his qualities will make up for any lack of numbers for sure. I see much potential in his future, of that I am sure.”

"You don't say!" Sona calmly replied. A little too calmly. "Here was me thinking your Pawn was Issei Hyoudou, but the way you're talking him up makes him sound like the reincarnation of Hercules!"

The two of them stared at each other, and demonic energy sparked in the air. This rivalry was real, this rivalry was intense. If it got any more heated they might set fire to the room itself.

“Oh, want to see for yourself how I am working him up? It will be quite the spectacle.” After she said that, Rias giggled, like she was imagining a particularly amusing training method.

"I have better things to do than scope out some lowly Pawn novice," Sona immediately replied, gesturing to the large mound of paperwork next to her. Which would take her all of ten minutes to deal with given the way she worked. "Besides which, the way your Peerage has been acting out, I think you may have to spend time disciplining them instead.”

"Oh that?" Rias chuckled. "Well... It can hardly be helped. You see, when I recruited this new Pawn it turned out that he had some previous contact with supernatural entities. Fallen Angels, before you ask."

And just like that, Sona switched from rivalry mode to pro mode.

“Fallen Angels sticking their head into our territory without permission?” This was a tricky problem. A Fallen Angel bothering a devil was one thing, bothering the little sisters of two of the most dangerous devils in existence was another thing entirely. Either whoever she was talking about was very stupid, or very dangerous.

"I thought you might find that interesting," Rias grinned, leaning over the desk to stare Sona in the eye. "My belief is that they were attempting to extract a Sacred Gear from Issei. So they cast a hallucinogenic spell on him, which reacted badly with the Sacred Gear..."

"And hit some of your Peerage in the crossfire." Yes, oh yes. Sona was really interested now. A spell capable of doing that to Rias' peerage was no joke at all. "Have you caught out the Fallen Angels yet?"

"Not yet. They think Issei is dead. I intend to have him ready to fight before we crush them. That is, unless you beat us to it."

Sona tapped her fingers together. Strictly speaking she shouldn't get involved. Issei was a part of Rias' peerage, which meant any mess should be hers to clean up. She'd found the Fallen Angels. She ought to be able to deal with them by herself.

Which brought a thought to mind. Sona had been wondering why Rias had come here. To gloat about her new Pawn before he'd even done anything substantial? That wasn't like her. But... what was like her was to ask for help without actually asking for help. Especially when it came to Sona.

"Of course, since we're not entirely sure of the nature of this Sacred Gear, we have to be careful when training him," Rias said. "Especially if there are lingering effects of the magic the Fallen Angels have cast upon him. While I can assure you we will take every precaution -"

"You want to make sure nothing like that kicks off again," Sona finished, leaning back smugly in her chair. "Oh my word. Have you selected a Pawn so powerful that you're afraid you cannot control him?"

"Oh no, not at all!" Rias waved it off and laughed. Sona didn't buy it. "We are simply going to push him as hard as we can go. So very hard... and long... to see how potent he truly is. Of course, it is up to you if you want to get involved. But I suspect this will be a rare opportunity to see a kind of power that is rarely seen within devil-kind..."

The point Rias was skipping around wasn't lost on Sona. If Issei's 'ability' was capable of that much, and he had taken all eight Pawns... then he could theoretically become a tremendous threat. Without even meaning to. Unchecked and uncontrolled power was much more dangerous than power used carefully with wicked intention. At the very least you could predict 'intent' and turn it against the user.

... Turn it against the user...

"I refuse the offer to attend personally," Sona said. "However, one of my peerage shall bear witness as a precautionary measure. She shall report back to me all of her findings regarding Issei and his Sacred Gear."

"And which member of your Peerage will be observing?"

"My Rook," Sona said, grinning privately to herself. "Tsubasa Yura."

<hr>

Well, this was boring. Dull. A waste of her time. Right now she was standing in the school gym, which had privacy wards placed all over the doors and windows to keep out anyone that wasn't a devil. Well. What a waste. Right over there were Koneko, Akeno and Rias. Three genuinely tough devils that she'd never really had much of a chance to throw down with. And Sona had told her to 'observe their training' of some new member of their peerage.

Well, the best she could probably get out of this was to learn a trick or two in training for the future. If they wanted to take a total nobody and make him into someone strong, then they had to go pretty hard. And who knew, perhaps she could get a chance to have some fun.

"Can't I at least spar with him?" Tsubasa asked at that thought.

"No," Rias firmly answered. "He is a neonate. The purpose of this is to teach him how to use his devil powers. He will not learn that from a spar with an experienced devil."

Tsubasa rolled on her heels. Shame that. She wished he would show up so they could get this over with.

"Hey girls!"

There he was now. Emerging from the boy's locker room wearing a white short sleeved shirt and... a tight... snug... pair of shorts... that left very little to the imagination.

Tsubasa's jaw dropped and she didn't know if she could ever pick it up again. That bulge! Th-That was his - That was ridiculous! H-how could something be that big?! That... that <i>perfect</i>.

"Uh, are you sure about these shorts?" Issei asked, trying in vain to cover himself. "They're a bit snug aren't they?"

"Don't worry Issei," Rias said. "We're all devils here, so that much shouldn't have any effect on us. Right Akeno?"

"Quite so, my King!"

What were they talking about? Tsubasa squinted, trying to get a better look at why exactly Issei was bothered by his outfit. At the same time, she tried to sense anything unusual of the magical nature, anything that would make one get interested.

Her senses immediately went <i>’ping ping ping’</i> towards Issei, like he was the source of some kind of supernatural force. It wasn’t quite demonic energy, perhaps more like the chi used by some mystic martial artists. Though even that was off.. like it were a concentration of only a specific type.. if she had to describe it.. she would have called it <i>manly</i>.

It should be noted that she was now staring quite intently at Issei’s crotch and didn’t seem to have noticed that fact. As far as Tsubasa was concerned she was staring at the primary source of the supernatural energy she was feeling. And it just so happened that this energy was centered on the bulge. The big bulge. The big perfect bulge that needed to be unwrapped like a Christmas present.

“Alright Issei, now we don’t quite know exactly what your Sacred Gear does. So far you haven’t truly <i>used</i> it consciously.” Rias began, "On that basis we are going to start you off with some physical exercise to see if pushing your body to its limits helps us understand your power."

"I guess that makes sense..." Issei said.

"Excellent!" Rias clapped her hands. Then Koneko showed up carrying a vaulting horse, which she placed in the middle of the gym. "Now. Tsubasa, if you could stand over here and watch Issei closely? Issei, I'd like you to vault that horse."

"Eh? Well, I mean... if you insist," Issei grumbled. You know, he had a good point. How was vaulting a horse supposed to help anything? The boy ran towards the horse while Tsubasa stood a fair distance off directly in front of him. Ah. She was here to catch him in case he had a burst of strength. That must be -

He put his hand on the horse and then vaulted, splitting his legs... and Tsubasa wobbled in place, her heart racing faster as that bulge became even more obvious than it already had been. It was the perfect chance to study it - purely so that she could find out the source of the magic of course.

"How was that?" Issei asked.

"Perfect," Rias said. She, Akeno and Koneko were all holding up cards that read '10' on them. "Next up, I'd like you to try holding yourself up on those rings. Tsubasa, if you could stand underneath him to catch him if he falls?"

She wandered over without really thinking about it. Issei pulled himself up. And Tsubasa found her eyes resting at crotch level. Inches away. The boy wobbled as he tried to hold himself up and did a better job of it than he apparently expected. But Tsubasa wasn't listening. All she could see was this strange and bizarre supernatural energy that she'd never encountered before. She had to know. She had to understand. She had to study it. Figure out what it was. After all, wasn't that why Sona had sent her here in the first place...?

<hr>

Things went on like that for about half an hour. Issei would be asked to do some kind of exercise. Tsubasa would be asked to stand in a position that gave her a good hard look at Issei's cock. The girls already under its spell looked to one another with pride, understanding and triumph. They could plainly see the glassy eyed look from this council member. She wasn't under per se, but she was... definitely entranced. Fascination bordering on obsession. As it should be. As was right for the King of Breasts.

"Alright, I think that's enough!" Rias clapped. "You don't seem to be doing anything unusual for an ordinary human, so we should try a different approach to activate your Gear."

"Huff... Huff... Sure thing..." Issei said, breathing heavily while leaning against the wall. "Uh... Actually... I was kind of wondering why this girl was here as well?"

"I am here because I have the power to Reverse magical effects," Tsubasa informed him. Now, strictly speaking she wasn't meant to reveal that. Sona had asked her to keep that quiet as it was a useful trump card. But Tsubasa.. Wasn't exactly firing on all cylinders right now. It was kind of hard to think, like she was dreaming and just going with the flow.

Maybe... it was those shorts that were to blame? Yes. The shorts. Maybe if she could get them off Issei she could take a better look at them. Find out what this thing was that she was seeing.

"Oh, that's a good idea," Issei nodded. "That way, this thing won't be able to hypnotise the unwary!"

"Huh...?" Tsubasa asked. W-Wait, hypnotise?

"Never mind that!" Rias hurriedly interrupted, pulling Tsubasa away while Akeno did the same with Issei. "For the time being why don't you - ahem - wait over here? Now, Issei! I have a theory that your Sacred Gear is a fairly standard double up ability. Now that we know it's perfectly safe, I think it might be a good idea to try out... an experiment."

"What kind of experiment?" the boy asked.

"Take. Your. Shorts. Off."

By this point Tsubasa was blinking away the hypnotic effect of Issei's bulge. Huh? Wait a minute, had Rias really said what she thought she had said?

"We're going to test to see if you can 'double up' the hypnotic power of your massive cock," Rias explained.

“Eh.. are you sure that this is saf-” Issei started to question, but his mistress gave him a very serious look. The sort that made it clear that not following her orders could have.. negative consequences.

"Issei, you heard what Tsubasa said," Rias interrupted. "So long as she's not looking, then she won't fall under its effect. At the same time, if something goes awry and you are able to hypnotise me, then she can reverse the effects. Isn't that right ,Tsubasa?"

She was so confused. But it was true enough. Whatever the effect was, she could instantly reverse it. There was no danger as long as she was ready to counter whatever was going to happen.

"Plus, if you don't drop your shorts in the next five seconds then I won't wake you up with a titjob anymore..."

Those shorts hit the dirt so fast they caused a sonic boom. By now Tsubasa was pretty much fully recovered from her long staring contest with Issei's crotch. It helped that she now understood that the mystical energy she was sensing was supposed to be hypnotic. H-Hold on here. A hypnotic penis? She'd never heard of anything so... so ludicrous in her life! She turned away, feeling her own heart picking up. This was obviously some kind of practical -

Oh. She'd been wondering where that Kiba boy was. He was right there. Above her on the ceiling. Holding a mirror. In which there was a reflection of Issei... alongside perfection.

The thought did occur to her that she ought to look away. But she couldn't. Even blinking was a chore. This was new. This was... Unlike anything she had ever felt before.

At this point, Koneko walked up to her, cat ears poking out of her hair and quietly adjusted her head so she was looking right at Issei and his big, hard cock. “Now, you got a job to do. Please do be prepared. Plus, it is a nice sight, isn’t it?” The white-haired girl said, her voice all but purring at the last part.

"Boost!"

And then perfection got even more perfect.

It shouldn't be possible. It's like saying to a mathematician "double infinity". You were already at infinite, so how could you have even more of it? Well, that's still what happened. It was as if the cock had reached out and wrapped around her brain. Not squeezing it, but hugging and caressing it and keeping it warm and safe. Nothing mattered, nothing but the cock and the wishes of its owner.

"Massssterrrrrr..." Rias slurred, dropping to her knees and quickly crawling towards Issei. That looked like a really good idea to Tsubasa just now.

"Tsubasa! Reverse it!" Issei yelled. Koneko jumped out of her skin. Akeno gasped. Rias gurgled without a trace of intelligence in her mind.

And so... she did exactly what her Master asked.

1. All of a sudden Issei is a girl with hypnotic breasts.
2. Issei's cock shrinks - but only until his Gear deactivates.
3. The hypnotic effect reverses, so that Issei is now the total thrall of the girls.
4. The girls wind up having to obey the opposite of his commands
5. Something else happens
