Chapter 17 Testing his Treasures

I don't own DxD; I just use its characters and techniques. All credit goes to its creator. Same applies for anything that I used from other animes.

Summer vacation begins and things get very interesting.

The sun was shining, it was a beautiful day out and a smiling Issei Hyoudou sat and watched the kendo club girls swim laps in a large pool dressed in various bikinis while he got a blowjob from a bikini clad Irina and Xenovia. It was summer break for Kuoh Academy and while Rias and Sona went to the underworld to visit their families, Issei was in Hokkaido relaxing at the beach side villa that belonged to Katase's aunt. Her parents were absent all the time, but her aunt made up for it by spoiling Katase rotten. Thanks to that, it was a simple task for Katase to borrow her aunt's beachside villa for a month even though Issei was going to be here also. Katase's aunt would check in once a week, but for the most part the girls would be alone with Issei and that's how they liked it. What they didn't like, was that Irina and Xenovia were there as well having been brought by Issei so the girls could work on the dragonic traits they got when he made them demi-dragons. Of course the kendo club had no idea about that and Issei intended to keep it that way.

The first training exercise was to split the ten girls amongst Irina and Xenovia and have them face off against the former exorcists in a kendo match. To the girl's shock, Xenovia and Irina won every match and as punishment he had the kendo club girls do 20 laps. Adding insult to injury, Irina and Xenovia gave him a blowjob while the girls did laps something that was amusingly hard to ignore. "Keep going girls" Issei smiled speaking to the girls still swimming and the two on his rod at the same time.

"Damn them" Katase cursed having finished her laps already and being drawn to the sight of them playing with Issei.

"Don't get angry Katase. Just get better." Issei smirked causing her to twitch more since she forgot about Issei's incredible hearing. One by one, the girls of the kendo club finished their laps and as a weird twist of fate Issei erupted onto the two girls in front of him just as the final girl hit the wall.

"That was impressive Issei." Irina smiled licking up the seed.

"Thanks but I need to have a chat with the girls for a bit. Why don't you go swimming to clean up?" Issei smiled.

"Fine by us." Irina smirked before getting up and going towards the pool. Once Irina and Xenovia were gone, the kendo club girls walked over to Issei who pulled up his trunks much to the girl's annoyance.

"So what's up Issei" Murayama wondered deciding to focus less on the fact he was getting a blowjob a minute ago and more on what he wanted from them.

"Ever since I became manager. Most of the time has been spent having as much fun with you girls as I could. However, that's going to change when we return from break." Issei said calmly causing quite a few frowns to appear on the girls faces.

"I never thought I'd see the day that Issei hyoudou got tired of his harem. Weren't you talking all the time about how you'd be harem king with your buddies before you came to us?" Murayama teased hiding her growing annoyance.

"I'm not tired of you girls at all. However things have changed and I've decided that I'll be stepping down from my position as kendo club manager once this camp is over." Issei announced to the girls shock. Did he love sex and everything that came with it? Yes. However, he cared about the girls enough to know that it was only a matter of time until somebody targeted them.

Instead of being outraged, the girls all looked at each other before nodding as though a massive conversation had taken place, "How about a deal Issei?" Murayama said calmly.

"I'm listening." Issei replied.

"On the last day of camp how about we face off with Irina and Xenovia again. If half of us win you stay on as our manager." Murayama replied. The girls were certain that the reason he was leaving was due to the fact Irina and Xenovia had beaten them so soundly. The fact he clearly slept with them also didn't help matters.

Issei was about to turn them down but received an amusing interruption, "So you think that in a month you can get strong enough to beat me or Xenovia." Irina smiled. Rather ironically, the girls concern was half right and Irina figured this was a chance for them to prove to Issei they were worthy.

"That's right. You may have caught us off guard this time because we didn't know what to expect, but we'll win next time." Katase said defiantly.

"Very well then girls you have a deal. To make things more interesting I'll do most of the shopping and cooking duties which will allow you girls to train how you want. Along with the occasional motivation on what you'll be missing out on should you fail" Issei smiled. A part of Issei was annoyed the girls didn't just let him go, but another part appreciated their devotion despite the dubious circumstances that led him to them.

"Sounds good manager" Murayama smiled with the rest of the club nodding their approval of the deal.

(Scene Skip)

The next few days were easy for Issei as he watched the girls train intensely to prepare for the rematch with Xenovia and Irina. Issei had to step in after the third day since training into the ground wouldn't do them any good and ordered the girls to go to the beach for a day. Something they agreed on as long as he joined them, "I don't know whether I should be annoyed with those girls for being so defiant or happy that they want to keep it going." Issei chuckled as he relaxed on a beach towel with the girl's things gathered around him.

"You should be happy considering the stupid plan you came up with to protect the girls" Irina chuckled as she relaxed on a nearby beach chair. Irina's bathing suit of choice was a simple white bikini that had a half cup up top and a matching white bottom.

"If I stick around it's only a matter of time till the Khaos Brigade targets them." Issei frowned.

"Yes and ironically staying by their side is the smartest thing to do." Irina chided. Issei wanted to protect them by hiding them away but they would still be targeted since it was one of his few exploitable weaknesses.

"Maybe… so" Issei frowned. It would seem he has a guest.

"I'm gonna go swim. I think our guest wants to speak to you in private." Irina said with a frown threatening to form having sensed the same person appear.

Issei simply closed his eyes and relaxed for a moment until he heard a figure sit down on the chair that was previously occupied by his childhood friend, "Some people have all the luck don't they Issei." A female voice teased.

"Did you get it Valerie" Issei said with a slightly raised eyebrow and his eyes closed.

"Yes but if you don't open your eyes and tell me how I look, you won't be getting the information until you go to the underworld. I did buy this outfit just for you after all." Valerie teased before walking in front of Issei not that he could see her.

Issei fully opened his eyes to see what Valerie was wearing and he wasn't disappointed. Valerie was wearing a silver top with a front zipper that currently hid her massive breasts and a black bikini bottom with her silver hair in a ponytail. It made for a pretty impressive look for the normally tomboyish Valerie. "Not bad" Issei smiled happily.

Valerie smiled back as she unzipped the top revealing her massive breasts before putting her hand between the large mounds and taking out a flash drive that she gave to Issei who quickly put it in his shorts. "The kid's picture is in here." Valerie explained knowing he would do the rest.

"What do you want for it?" Issei deadpanned. She agreed to help him but said it would be in exchange for something that she would decide on later.

"I'll tell you another time. It looks like your kendo girls just noticed me and I think some of them are coming back this way." Valerie smiled before leaving with a smile and a swing of her hips.

'Damn that girl.' Issei mentally chuckled as the kendo club girls returned to his side. While the kendo girls sent various complaints his way about why Issei was talking to other girls, Irina and Xenovia both gave him a glance that suggested they'd discuss the meeting later. He was lucky the girls didn't realize who it was, or he would have even more irritating questions to deal with.

(Scene Skip)

The next day, the girls were back on the beach but instead of having fun they were training. The whole team was in their gym outfits and doing drills on the beach instead of at the poolside villa. Issei had no idea why but he wasn't about to complain. "If I didn't know any better they're trying to show what YOU will be missing instead of the other way around." Irina smirked as she found herself sitting on the beach chair in a simple yellow t-shirt with a pair of blue shorts with Xenovia on the opposite side of Issei in a green t-shirt with blue shorts.

"Maybe so but it doesn't matter. You girls won't lose to them no matter how much training they do." Issei smiled back in his own beach chair in just some trunks.

"I'm still surprised you're actually leaving them. I thought the kendo club was your way to avoid dealing with the supernatural" Xenovia said bluntly.

"It was, but recent events mean that I can't be too careful." Issei frowned.

"Is that why Valerie came by to see you yesterday?" Irina deadpanned.

Issei twitched slightly but stayed focused. "No. Valerie came by because I asked her to use her old contacts to investigate the incident that got Asia kicked out of the church."

"I see and what did she discover" Irina questioned having long been curious about that herself.

"Her information added nothing I didn't already suspect but she did have a picture of the devil that Asia healed." Issei replied.

"Well it's a start" Irina admitted. They couldn't confirm anything until he arrived at the underworld but getting that would be a nice start.

"Yep there's nothing I can…. do." Issei paused again as he noticed something that made him twitch royally. Something that the other two girls next to him noticed as well.

"Hey Issei isn't that Kiryuu and some blonde girl walking towards the kendo club." Xenovia said out of the blue before pointing to two figures coming towards the now relaxing kendo club.

Admittedly Issei hadn't seen Aika Kiryuu much since they changed classes, but when he had he was pleasantly surprised to see the girl abandon her pigtails and glasses in favor of contacts and long hair. The girl in question had the same gold color eyes as Kiryuu and the same brunette hair but Kiryuu's went just past her shoulders instead of the ponytail this girl was currently sporting. He also saw that she was wearing a dark red bikini that looked pretty good despite the fact the owner had low B cup breasts. "While that girl does look very similar to Aika that isn't her? If I had to guess she was her twin sister." Issei replied with a smile. He heard rumors Kiryuu had a twin that went to Nochizuri Prepatory, but he was never able to confirm them until now.

"I see" Xenovia said calmly.

"Putting Kiryuu aside, what the hell is Genevieve doing here." Issei frowned. Next to the mysterious twin was Genevieve Arcana who once again decided to grace Issei with her presence. Genevieve was wearing a bikini herself with a white and red top and blue bottom and while the outfit did show her body off nicely, Issei was far more focused on what she was doing instead of how she looked.

"That girl truly has a death wish doesn't she?" Irina smiled having heard about issei's various meetings with Genevieve.

"Yep and there's nothing we can do but hope that she leaves." Issei replied. Unfortunately, fate had other ideas and Katase walked towards him with the two girls in question. Issei barely held back a smile when he saw the look of nervousness on Genevieve's face and realized this wasn't her idea at all.

Issei, mind if these two join us for lunch." Katase smiled.

"I don't see why not. I recognize Genevieve from your kendo matches, but I've never met the other girl." Issei said calmly trying to hide his knowledge.

"My name is Momiji Kiryuu. My twin sister Aika goes to Kuoh like you guys. We rented a beach house nearby and when Genevieve recognized one of the girls from your school running along the edge of the beach I figured we could go say hi." The now named Momiji smiled.

"Pleasure to meet you. Well since we're going to have some guests for lunch I should get back and start preparing." Issei said calmly hoping that would be it.

"Aww why not stay and play. You look like you haven't left that chair since you arrived." Momiji smiled reaching out to Issei before he put his hand up.

"I'm okay. Maybe I'll get some sun later on." Issei replied calmly trying to keep things civil.

"Your loss. It's not every day one guy gets to play with so many pretty girls in bikini's."

"I guess so" Issei replied trying to hold back a snort as he got up from his chair. Considering he slept with every girl here besides Momiji he didn't exactly care about playing with them. As he went back to the villa to prepare lunch, a part of him was starting to wish that he had gone to the underworld.

(Scene Skip)

The group sat down for lunch in the massive dining area that had two large tables. Issei Murayama Katase Irina Xenovia Genevieve and Momiji sat at the first table with the remaining members of the club taking the other. The girls loved the food from Issei and as everyone sat down there was a good mood all around at least for a little bit, "Hey Issei has my sister ever used that weird dick trick of hers on you." Momiji said bluntly catching Genevieve and the other girls off guard.

"Where the hell did that come from Momiji?" Genevieve exclaimed a blush forming on her face.

Issei wasn't as caught off guard and he found it amusing, "Yes she has. Don't tell me you have a similar ability to hers" Issei replied.

"My ability involves intercourse also but it's a lot more interesting. In my case, I can tell if a guy and a girl have had sex because of the unique pheromones they exude." Momiji smiled causing most of the girls to do a spit take at the implications.

"How's that possible." Murayama gasped trying to not choke on her drink. After all the entire club had sex with Issei and seeing that exposed would not be good.

"Every person, no matter who it is, possesses a unique pheromone. Every time somebody has sex with another person their pheromones stay on their bodies and I can see the pheromones. Admittedly it's not as fun at a school like Nochizuri, but occasionally I get some gems." Momiji revealed before looking at Issei calmly just for her face to go crimson and for blood burst from her nose in an impressive nosebleed.

"Momiji!" Genevieve exclaimed rushing to her friend.

"What the hell?" Murayama gasped.

"Something similar happened the one time Kiryuu was foolish enough to try her little trick on me. So what did you see Momiji?" Issei questioned with a look of amusement in his eyes.

Momiji quickly gathered herself before staring at Issei with a look of awe on her face, "I saw that you have a very healthy sex life Issei. In fact, the only person in this room that you haven't had sex with happens to be me." Momiji replied dropping a hammer on the room.

The room was silent for a moment until Katase spoke up, "Call me crazy, but you said the only person in the room that Issei hadn't had sex with was you right?" Katase said with a twitch hoping that it was some sick joke.

"That's right. I can sense pheromones from every girl in this room on Issei's body besides me. Is something wrong" Momiji questioned with a look of amusement on her face.

"Our club has sex with Issei a lot, so it was obvious that our pheromones were on him. The same cannot be said for your classmate Genevieve." Katase replied with a cold fury threatening to form on her face as she turned towards the blonde. "So Genevieve, when did you sleep with our manager?" Katase growled

"I…." Genevieve said bashfully not wanting to bring this up.

"Remember how Genevieve dragged me away for the screening before our match at Nochizuri." Issei smiled deciding to bury the girl in the proverbial sand.

"Issei!" Genevieve exclaimed with a blush on her face hoping he would stop right there.

"Yeah we do. I also remember you came back just fine and Genevieve never showed up."

"Oh I get it. Genevieve must've tried to seduce Issei and it backfired badly." Corinna smiled.

"Pretty much. She barely lasted a few minutes before fainting" Issei replied. Of course their actual romp was much longer but the girls didn't need to know that.

"Damn it Issei, why did you tell them?" Genevieve pouted the blush still on her face. It was a half-truth but it was not something she wanted out in public.

"If that's the case why was she so scared earlier. I mean issei's penis is a monster but that shouldn't cause her to be afraid" Another of the kendo girls said. This one was had dark brown hair that framed her body with hazel eyes and a slim frame.

"What do you mean scared" Murayama said out of nowhere.

"Normally she's so serious and impassive, but I noticed that she was sort of nervous as she walked towards us. When she turned and saw Issei I swore she paled for a second." The girl explained.

Genevieve froze since this couldn't end well for her. Most of her excuses would be negated from the fact they already had sex. Amazingly enough it was Issei who saved her yet again, "That's enough Ryoko, I was a little rough on her that day so she probably had flashbacks of that. You guys know that I can get rough on occasion." Issei explained with a smile.

"Got it" Ryoko replied nervously since Issei's rough streaks were well known amongst the girls.

"Well that's enough about my sex life. Let's discuss something else." Issei said in a tone that said it was more than a suggestion.

"In that case, how about we discuss the fact that on our first night here this ass told us he was leaving as manager at the end of our little trip." Murayama smiled seemingly turning the screws on Issei.

"That's shocking. I mean you get to have sex with all these cute girls. Why would any guy want to leave?" Momiji replied.

"Recent circumstances have made me re-evaluate the situation. While I do adore the girls and the sex is awesome. I felt as though it would be best for the girls if I step away." Issei replied.

"Oh and when did you come to that decision" Momiji said calmly.

"I've been thinking about it for a month or so, but every time I considered bringing it up I was reminded by you girls what I'd be missing." Issei replied cheekily.

"That explains why you haven't been as into it as before." Murayama frowned.

"So wait a minute. You've been thinking about quitting for around a month and just recently decided to go through with it." Genevieve said in shock. If she remembered correctly the attack on Kuoh was a month ago so that would mean that.

"That's right. The girls don't need me for anything outside of motivation so I figured it might be better for me to step away. Now if you don't mind I'm going to go do the dishes" Issei said calmly.

"Why don't I help you Issei. I am a guest after all." Genevieve suggested.

"Absolutely not" Issei replied coldly before leaving the group.

"Well that was harsh" Momiji noticed.

"Yes… yes it was." Murayama replied with a narrowed eye. Issei was never that cold and Genevieve clearly knew something that the Kuoh girls did not.

(Scene Skip)

Nightfall arrived and Issei was relaxing on the sofa bed that had become his spot for the last few days. The girls were split between the three upstairs bedrooms with Irina Xenovia Murayama and Katase taking one room with the other eight members splitting the other two. 'What a day' Issei thought to himself. It took every ounce of willpower he had not to strangle Genevieve and luckily he held on.

'Partner it looks like your day isn't quite over.' Ddraig warned mentally as a figure approached him.

'Of course it wouldn't be that simple.' Issei groaned as Murayama approached. Issei appreciated the short sleeved pajamas she was wearing but he knew this wasn't the time for pleasure. To emphasize that point Murayama stayed five feet away from Issei.

"We need to have a little chat Issei and I think you know about what?" Murayama said sternly.

"I actually don't. Sleeping with Genevieve was a choice and it's not as though I was exclusive to your club." Issei replied hoping to distract her.

"It's not about that, though I must admit I was annoyed by that, it's more about the real reason you're leaving us." Murayama said coldly.

"Oh" Issei said with intrigue.

"When I challenged you that day, it was with the understanding that it was between you and me. It might have ended with an orgy because the girls interfered, but it was okay because the Hidden Dragon was unleashed and I took pride in knowing that I was the one who caused it. When you went after Yumi, I was a little surprised, but I didn't complain much since once again you came back to me and the club. Then Karlamine transferred in and instantly she was as close to you as we were and let's not even get into Irina and Xenovia's transfer." Murayama revealed as tears began to form on her face.

"Mury" Issei said calmly but as he moved towards her she spoke again.

"Stay right there Issei because something is wrong. Why are you so willing to leave us now when you've stayed around for so long?" Murayama said angrily. Her tears and emotions kept flowing as she wondered what she and the others had done. At first, she thought it was because of their defeat but the more she thought about it, the less she believed that.

Issei wanted so bad to tell her but he couldn't. "I don't see the problem Murayama. We agreed that If you girls beat Irina and Xenovia I'll stay." Issei replied calmly reminding them of the agreement they made earlier.

That's not good enough!"

"Huh" Issei replied in confusion.

Murayama finally closed the distance and stood right in front of Issei, "You're hiding something from us Issei and even if you stay there's no guarantee you might not think of leaving us again" Murayama said boldly.

"Is that so" Issei smiled standing up so he was face to face with Murayama.

"That's right. You once called me your treasure Issei and I still take some pride in that. It's time for me to remind you how valuable of a treasure I really am." Murayama said defiantly before pushing Issei back onto the bed.

"So that's how we're going to do it huh" Issei smiled.

"Yeah" Murayama said with a fire in her eyes that Issei had never seen before.

LEMON START

Murayama pounced on Issei and slammed her lips against his trying to quickly take control of their encounter. She knew how good Issei was at this and she knew if he got his bearings she was in trouble. Just as Issei had done many times she slid her tongue against Issei's lips and when he easily parted ways she attempted to dominate the kiss. To her surprise Issei allowed her to do so and after a minute she pulled away with a trail of saliva to show her efforts. "How was that Issei?" Murayama said with pride on her face as she straddled Issei's hips making sure to press her body against the shorts he was wearing to bed. To her surprise he was without boxers which in truth shouldn't have been that shocking considering the amount of sex he had.

"Not bad actually, but you'll need to do better than that if you really want to impress me" Issei chuckled before moving up to meet Murayama and kissing her on the cheek.

"Alright" Murayama smiled before reaching for his shorts which she quickly pulled off exposing his prick and wrapping her lips around his shaft with practiced ease. Issei grunted as the brown haired girl deep throated his massive member taking almost 8 inches in before her gag reflex kicked in. Before Issei could react, Murayama bobbed her head up and down Issei's shaft in order to give the young man as much pleasure as possible.

"Keep going Murayama you're doing great." Issei smiled. It was impressive considering she never went that far before. Clearly their time together had improved her oral skills.

Murayama smiled at Issei's approval and decided to give him more. "We're just getting started Issei." Murayama boasted her pride growing by the minute. The brown-haired girl quickly tossed her pajama top to the side revealing her bra-less breasts and wrapped the large orbs around his massive prick letting them take over.

"That's the stuff" Issei smiled. He could've easily taken over, but Murayama wanted to prove herself and he would let her. As Murayama continued her ministrations, she pushed Issei around to when he thought her limit had arrived, but when his limit was nearly there Murayama stopped.

"I told you I was going to prove myself Issei and I'm far from done." Murayama smiled as she pulled away from Issei again in order to tease him. The brown-haired girl pulled off her pajama bottoms revealing a crimson red pair of panties which she slowly slid down her body.

'She's good' Issei smirked well aware that Murayama was trying to tease Issei and get him to overreact.

"Are you ready Issei?" Murayama smirked as she straddled his still rock hard member and slid in from above moaning happily as they were finally connected.

"Not bad at all Mury." Issei smirked.

"How's this Issei." Murayama grunted as she began bouncing up and down his shaft at an impressive speed.

"Nice job Mury." Issei grunted enjoying the young woman's movements. She was doing so well that he wasn't going to stop her from showing off.

Murayama couldn't help but frown at Issei's nonchalance and forced her body to move faster. "I'm… not… done." Murayama grunted wanting to make Issei submit to her but little by little her determination was wavering.

Noticing as much Issei smiled and decided to finally take control pulling up to Murayama so they were face to face, "That's enough Mury you've proven yourself." Issei smiled as he wrapped his arms around Murayama's waist and kissed her taking back control.

'Damn' Murayama cursed as Issei began thrusting up pounding her body and little by little the control she thought she had was gone and Issei dominated her yet again.

"If it makes you feel better. You've proven yourself as my treasure and now it's time for me to take care of you." Issei smiled as he flipped their bodies around before moving Murayama to the middle of the bed.

"So you'll stay without the challenge" Murayama said hopefully.

"I'll think about it" Issei smiled as he began hammering into Murayama's snatch. The young woman's moans of approval filling the room.

"Issei… Issei… Issei" Murayama cried out.

"You've done well Murayama now just let me do what I do best and make you feel good" Issei smiled before gently rubbing Murayama's face with his right hand.

"Okay" Murayama said submissively allowing Issei to take over and take over he did. As Issei continued to fuck Murayama the kendo vice-captain was further reminded of just how much Issei had changed her and the other members of the club and she wouldn't let that get away.

"I'm cumming inside you Murayama." Issei said happily after ten minutes showing Murayama that she had earned her reward.

"CUMMING" Murayama roared as Issei's seed rushed inside her.

LEMON END

"You've done well Murayama." Issei smiled as he fell onto the bed.

"Issei please don't leave us." Murayama said softly as she curled in next to him and shut her eyes wanting to enjoy the warmth that he provided her even for a little bit longer.

A smiling Issei grabbed the covers that were tossed to the side during their romp and pulled them over their intertwined bodies, "I don't want to Mury, but in the end I may have to" Issei said softly himself before kissing Murayama on the cheek and falling asleep as well. Things were going well for now but with Genevieve around and the Khaos Brigade beginning to stir there was no telling when his peaceful situation would come crashing around them.

That's it for Chapter 17 and summer break is off to a fascinating start. Next time Issei's fear comes to pass and his two worlds finally collide.
