Story: Cocknosis DxD

If you'd told Issei that all of this would be happening to him about a week ago, he'd have called you a liar with a very active imagination, and by the way have you put any thought into writing porn? Seriously, Issei may be a guy with a positive outlook on life, believing that one day he would gain a harem through hard work, but he wasn’t quite crazy enough to think that next week he would be jury for a wet t-shirt contest for some of the hottest girls in school.

But it was happening and he was certainly not going to complain!

“Okay, here is the hose, Koneko please put the bucket there.” Rias said, handing a red water hose to Issei and giving him the responsibility to <i>release their full appeal</i> in the competition. The petite white-haired girl next to her put down a pair of buckets on the ground.

One of them was empty while the other was filled to the brim mashed ice-cubes. The first, labelled as "round one". The second, "round two." Not exactly imaginative names, but 'bouncy wet boobies' and 'hard frosty nipples' was probably a little too blatant.

No doubt in his mind. Becoming a devil was the single best thing to happen to him ever, ever, ever!

“Okay then, we count on you!” Rias continued, stepping to the side and pushing a button on a music player they had brought along. Quickly a sultry voice started to sing a catchy tune and Rias stepped towards the other two participants of their little game.

"I hope you're ready to lose this one, my King," Akeno said, reaching under her boobs and hefting them up.

"Size is nice, but don't underestimate my technique," Rias said, twirling in place and putting her hands on top of her head.

"What does technique have to do with a wet t-shirt contest?" Kiba asked.

"My friend, sit down and enjoy!" Issei grinned. "Oh, the things I have to teach you."

“I-is it really okay to join..? I was only supposed to help with training..” Tsubasa pondered, even as her gaze strayed back and forth across her fellow contestants. “Well.. tits <i>are</i> awesome.</i>” She mumbled, the words repeating in her mind over and over.

“Hmm..” Koneko remained quiet, already concluding that Rias and Akeno didn’t see her as a threat due to her lesser bust size. It bugged her, but if they were busy competing with each other , they wouldn’t interfere with her. And Tsubasa was too dazed to be much of an opponent anyway.

As for Issei... He'd be the judge for the time being, but when the time was right he'd join in too. His new girl transformation felt really fun and right to play into, and taking part in a wet t-shirt contest was absolutely the sort of thing he wanted to try with it.

But first things first: He had to judge.

"Begin!" he said, and Kiba lifted the hose. To their credit, not one of the girls reacted against the water. If anything they were all trying to lean into it. Get as much of their shirt soaked as possible. Even though he had seen quite a bit more of three of them by now, there was something magical about this contest.

Ah. Now that was a thought. Given the way his enchanted hypnocock was, if he got hard (hah, if) from this contest then he'd tear a hole right through his trousers. Which meant he had no choice but to take them off. Luckily these devils were immune to the effects (until he boosted it), otherwise he'd be feeling quite bad about subjecting them to it.

Still. All four of them did lick their lips as soon as they caught sight of it. And, on top of that, they all got quite a bit more competitive.

"So my King? Where is this vaunted technique of yours?" Akeno asked.

"My Queen, you should learn not to ask for something, when it will result in your utter defeat."

Rias wasn't kidding. The other girls hadn't quite grasped the beauty and pageantry of the wet t-shirt contest, but it seemed as though she did. A girl didn't just win by having the nicest rack. You had to work for it! You had to dance for it! That was what technique meant, and Rias had it in spades!

Yes, yes, Issei could immediately tell that she was avoiding many of the common pitfalls a new contestant in this field might fall into. She wasn't focusing <i>entirely</i> on emphasising her bust. Instead, she half turned to the side and began to grind her hips while keeping her back nice and straight.

Then she twirled around, stepping a little back and towards the little bamboo forest at one end of the school. Her intent became obvious as she quickly took advantage of one of the poles, pushing her breasts around it and rotating as if it were a stripper pole.

"Oh, is that all you meant by technique?" Akeno asked. For a moment Issei thought that she would raise the stakes by joining in on Rias' pole dance - but no, she stepped away from the bamboo instead, getting closer to the hose! Then, she tugged up her soaked through shirt and tied it up underneath her breasts and began to work those tummy muscles while waving her arms out to the side. "Now watch what I can do when I put a mere tenth of my full power into this belly dance!"

"Ohhh, they're going shounen style in this belly dance!" Issei yelled. "Note to self, plan out a shounen series centered around erotic dance!"

"I'll draw the art," Kiba volunteered.

Oh, what a wonderful new friend he had found, he would have never thought that a handsome bastard like Kiba would actually be a good guy! He would have to make up all the times he cursed him silently in the past, perhaps help him get laid? Wow, he hadn’t thought there would come the day that he would think about playing wingman for someone else. But after being so blessed, he couldn’t help but think of giving some back to the world!

"Koneko, we're being ignored!" Tsubasa said. "Quick, we must utilise a devastating double team move! Grind your ass up against me while I grope your breasts!"

And now some yuri action on top of everything else! Issei broke out into tears, and not just because his rapidly hardening dick had slapped him right in the face. Well, okay, mostly because of that, but also because... it was so beautiful.

Koneko though wasn’t going to just leave it be with a bit of kissing. Rather, she grabbed onto her fellow Rook and whirled her around so her breasts were bouncing wildly. Then when Tsubasa landed, Koneko twisted so she was headover, ass pointing towards Issei and legs raised for her partner to hold.

The two were soon a whirlwind of motion,taking advantage of their unique strengths. Koneko’s booty and dexterity, and Tsubasa’s breasts. At times meshing together, lips barely a millimeter apart and at others once again whirling apart.

Issei enjoyed every second of the entire thing.

Although, one thing was bothering him about all of this. What on earth inspired Rias to have a wet t-shirt contest anyway?

"Hey! What are you perverts up to out here?!"

<hr>

Rias Gremory was not a fool. Make no mistake, she was more than a pretty face and an enormously powerful devil. She was smart. She was canny. Perhaps not the best tactician out there, nor even in the top fifty, but she could think and scheme and plot.

So, let's review her situation: She wanted Issei to be the King of Breasts. He didn't seem to want to intentionally hypnotise anyone. Therefore, it was in her best interests to make him do so by accident.

Think about it like this. There were several ways this could play out. The first alternative: Issei went as a girl and took part in this contest with her heaving hypnotits. In which case, Rias wins when the kendo club shows up. The second alternative, he stays male and keeps his trousers on. In which case his inevitable erection from watching a wet t-shirt contest involving four hot girls would destroy his clothes and he'd be swinging free until he went even harder. The third alternative? He didn't turn around, in which case you'd be damned certain they'd do it for him.

The fourth possibility, that they didn't show up... Well, they wouldn't lose anything by having a little fun, and he'd probably be more open to having another contest another day, when they probably would show up. Win, win, win. All hail the King of Breasts. All hail Rias' genius.

“Oh my god, is that Rias Gremory? And Akeno-senpai.. I had no idea they had perverted hobbies like that!” One of them shouted, voice tinged with disbelief and horror.

“Even Koneko, and Kiba too! W-was the Occult club just an excuse to play perverted games! To think I worked so hard in hopes of joining one day!” Another one continued in the same shocked voice.

Ah, how horrible. With everyone having seen that, her club's reputation would be ruined. Even better, now Issei had motivation to play along.

"W-wait, no! It's - it's not what you think!" Issei protested, seemingly forgetting his state of attire. "Um! Rias! Explain to them what we're doing, please!"

“We are just having a perfectly ordinary wet t-shirt contest for Issei and Kiba’s enjoyment. They have worked hard and deserve a bit of fun and naked skin.” She said, trying to not look at how Issei’s cock waved from left to right due to his sudden turn towards the kendo club. They should start noticing it any moment now.

"Perverts," Murayama said. Guilty as charged. "You, at least put some underwear on! I don't want to see your big... hard... Uh..."

A couple of the girls in the kendo club had started unconsciously stroking their sticks. A good start, but only a start. Now for the fun to begin.

“Come on, don’t be spoilsports.” Akeno called out, stepping next to Issei and hugging him from aside. “It was just a bit of fun, you cannot say you never wanted to join a wet t-shirt competition.” Issei looked at her and she patted him on the head.

Koneko came from the other side and also hugged Issei, stroking his cock with one hand.

“We cannot stop, the winner hasn't been decided yet.” She said, somehow sounding almost bored even though there was clearly a hungry look in her eyes.

Perfect, Rias smiled at the way the two were distracting Issei from the fact that the kendo club was falling to the glory of Issei’s cock. Yet more busty babes completely and hopelessly falling under his influence. If she played her cards right she'd have the entire school at their mercy by the end of the week. Then, they'd begin their preparations to move into the world of the supernatural.

"Ah-Ahhhh!" Issei gasped, suddenly realising what was happening. He moved to cover himself up, so Rias took the next logical tactical step and slid up next to him, putting his talented fingers to better use by putting them up against her soaking wet breasts. Then, to keep him from objecting, she kissed him on the lips and let the other two take the lead.

"You girls do seem too tightly wound up for your own good," Akeno said. "Why don't you join in as well?"

"Wh-why don't we...?" Murayama repeated. Then she shook her head, as if trying to get rid of the thought. Good luck, girl. It's there now. Rooted in through the power of cock. "Be-because it's dirty..."

"How can it be dirty when all this water is flowing?" Koneko asked. A ludicrous question from a logical point of view. But where Issei's cock was concerned, logic had absolutely no place.

"Say, Issei? Why don't you join in the next round?" Tsubasa asked. "Let us judge the second round. You versus the kendo club. If you win, they'll have to do whatever we say. If we lose... same deal."

“Ah, good idea!” Issei said, popping away from Rias' teasing lips. Which was fine for her. She nuzzled his neck instead. He was seeing this as the solution to his little hypno-cock problem. He didn’t want to turn the kendo club into the same horny state as Aika, but his female version should be far less problematic!

“Ehh.. judge?” Murayama asked, a puzzled look on her face even as the rest of the Kendo club shuffled around in a mix of confusion and arousal.

“Yep, you judge and everyone else joins.” Akeno said, making the whole thing an absolute truth in the club member’s minds. The sun was yellow, the sky blue and they would join the wet t-shirt contest.

Oh, this was even better than 'according to plan'. Rias had merely wanted to get them hooked on Issei's cock. Now they had that first nibble on that sweet addictive sight - and almost immediately after they were going to get hit by hypnotic tits as well! By the time this contest was over they'd all accept it as truth that Issei was the King of Breasts without Rias having to whisper it in their ears.

Murayama blinked as she came back to herself. Then she clapped her hands. "Alright girls! It's all of you versus Issei in a wet t-shirt contest! No need to even change out of your dogi, you'll crush him with even that kind of handicap!"

"Pride cometh before the slut," Akeno muttered to herself, half amused by her joke. Rias elbowed her. Not the time. Issei was standing off to the side of the field, taking a deep breath. He then said two simple words.

"Reverse-Boost!"

Goodbye to that amazing hypnodick. Hello to Issei-chan and her amazing rack. The boy-turned-girl whirled around in place (still wearing only her school uniform top) and gave a cutesy salute that was really over the top.

"Issei-chan is here to knock your socks off!" she tittered. Oh, but Rias could only facepalm. Too much! It's far too much! Especially with that chest bouncing all over the place!

"Did- did he just turn into a gi-gi-babe," one kendo club member asked, licking her lips and rubbing her hands down her neck. Watch your eye line, girl.

Unfortunately, or fortunately if you asked every participant here, Issei’s school uniform was for boys. Meaning, it hadn’t been made to accommodate a pair of melons bigger than her head. So after transforming, the top strained, carely holding on for a few moments.

Then the sound of half a dozen buttons popping could be heard and enough cleavage to drown a small army was revealed. You could hear every member of the kendo club moan a little in the moment Issei stepped forwards and the jiggle of those tits - sublime.

Do note that not a drop of water had hit them yet.

Issei stood in the middle of the line while the other girls stared at her. Rias couldn't stop smiling. This was going to be amazing.

"Begin!"

"Hoooo! Is that the ice water?!" Issei yelped. "Yipes! Some of it got into my c-cleavage! Ahhh!"

"My, my," Akeno gasped, fanning herself down. "All Issei is doing is jumping up and down in place, but it sure does beat all of our dancing."

"Buh...." Rias nodded in agreement.

"You know, now that I'm thinking about it..." Murayama slurred. Oh dear, the poor girl was wobbling a bit. Oh wait, so was Rias. God, she wanted nothing more than to bury her face in those tits. Truly, Issei had well earned the title of King of Breasts in every way that mattered. "Having you guys... judge this contest... seems kinda... Bad? I mean, you're incentivized to make Issei win..."

"Who do you think should win?" Akeno asked.

"Yipe! An ice cube got under my shirt!"

"Isseeeeiiii..."  Murayama's tongue flopped out of her mouth. Good girl. Cue Tsubasa tilting her head to the left and now the two of them were slipping each other some tongue. Gotcha.

“Heeeelp!” Issei said, trying and failing to get the frozen piece of water out of her cleavage. If anything, she was just making it worse.

“Sure.” Suddenly there was Koneko, then she was upside down.

Issei blinked a few times and stared at Koneko’s chest, her nipples visible through the wetness of her shirt. Like two tiny diamonds trying to pierce a pane of glass. It took her a few seconds to get her bearings back, and notice that not only had the ice-cubes in fact fallen out of her cleavage now that the short girl was holding her like this.

“Ehh.. Koneko?” Issei asked and only got a muffled moan of pleasure from above him. Right, then that thing pressing into his tits was in fact the devil in question.

Oh, and his top had slipped down a good bit, so Koneko was pushing her face into naked underboob. (Or was it called something else since Issei as upside-down?)

"Hey, girls! Quit staring!" Issei said while upside down. "Don't you know, in a wet t-shirt contest, you gotta win by dancing while you're being sprayed down!"

Very well. If that is what the King of Breasts wanted... cue the ORC and the kendo club dancing for his (currently her) amusement.

As for Issei, the same thought from before came to the forefront: If you'd said this would be happening a week ago, you'd be getting called a liar.

1. Let's continue with this contest for a little longer.
2. Time for Issei's first contract requests! They don't go quite as he expects.
3. Meanwhile, how is Aika getting on with Asia?
4. Sona notices something weird is going on with Issei, and pulls in help to investigate.
5. Something else
