Chapter 1 Part 5

"Yes! Yes I want you to join my peerage! Please Issei, please let me prove myself to you! Let me prove myself worthy of your love! Take it, take me! Take everything Issei!"

Her engagement and her duties as heiress forgotten, Rias Gremory laid her soul bare to the man who had so utterly changed her in such a short time and begged him to just fuck her already. And Issei obliged, snorting derisively and in one easy moment, pushing her panties aside and shoving his hard thick cock into her sopping wet cunt from behind.

Rias' eyes widened and her lips opened up while her lower lips spread around his cock, but luckily Issei was prepared. His hand closed over her mouth and muffled the scream of pleasure that emanated from it a moment later. He paused briefly, having taken Rias' virginity without hesitation but kind enough to give her just a second to adjust.

And then Issei Hyoudou began to fuck her and it was everything Rias had ever hoped and dreamed for, ten, no, a thousand times better than her greatest fantasy! His long powerful thrusts into her needy cunt pushed her up against the fence each time, but Rias could care less. Her mouth was open as a continuous moan left her lips. Very briefly and very blasphemously, Rias momentarily wondered if this was what Heaven was like. If this was, she could finally understand why some humans were simply unwilling to make a deal with a devil in the hopes of going there.

The red head's mind snapped as she came for the first time around Issei's cock, mostly because it was far from the last time and once the damn broke, Rias Gremory was climaxing nonstop as Issei plowed her from behind. Her eyes rolled back in her head and her tongue lulled out of her skull as Issei hooked his fingers into the side of her mouth rather than cover it up entirely.

Rias Gremory was the picture perfect image of ahegao in that moment, completely and utterly lost in the pleasure of Issei's brutal pounding of her once virgin cunt. She clawed at the chain-link fence before her, but ultimately gave up, her arms falling limp at her sides and her body simply shaking and jiggling in time with Issei's powerful thrusts up against her backside.

Eventually, Issei came. Rather than being the final straw, which for Rias Gremory had long since passed, Issei's release was actually a bit of a calming force for the beautiful red head. Once he'd filled her with his seed and pulled his amazing cock out of her quivering quim, Rias could finally think straight again. She slowly sunk down to the ground, leaning against the fence for support and gasping for air. Issei stood over her, waiting. For a belated moment, Rias wondered what the young man was waiting for.

Then she realized. Slowly, very slowly, Rias shuffled herself around and looked at Issei's filthy member. Without having to be told to, the crimson haired beauty, a pureblood devil, heiress to one of the seventy two pillars, leaned forward and began to clean the cock of her master with her tongue. The transition of thinking of Issei as a potential recruit to thinking of him as her lord and master, the love of her life and the center of her world, was completely seamless.

Rias, utterly mind broken in the same way Ddraig had been by this point, simply lavished praise along her Master's shaft until finally he grunted and pushed her away. Then, the two of them got dressed and she led him down off the roof, ecstatic as he allowed her to show him the way to the Occult Research Club's base of operations.

-x-X-x-

Issei lounged on a long couch, an amused smirk on his face as Rias panicked in front of him. The girl had stripped naked as soon as they'd stepped inside the place and so he'd done the same. Now he sat there, leaned back and relaxing as he watched his latest conquest try to work her special brand of magic. In this case, he amused himself as Rias' efforts to add him to her peerage failed.

First, the red head had tried to place a knight piece in his breast. His body had rejected the piece outright and a pouting Rias had put it down and tried to replace it with a Rook. This also failed, leading to her trying the Bishop as well. That didn't do any better. In the end, it was obvious that Issei could not fit into any of the three categories. His power could not be pigeonholed, though it rankled at him that the only other option was Rias' pawn pieces.

When Rias had finally decided that her pawns were the only way forward, she hadn't insulted him by trying only one at first. Instead, the girl had moved straight to four, sticking them in him one after the other. At first, things had gone well. His body had not rejected the pawns as it had the more specialized pieces. But he also had not turned into a devil, despite having four pawns inside of him.

And so Rias had put a fifth in, also to no visible effect. A sixth had followed and now she'd just inserted the seventh. Issei's amusement stemmed from Rias flailing about the room, her tits jiggling beautifully as she held up her last pawn.

"W-what if it doesn't work Master?! What if you're too strong for even ALL of my pawns?! How will I make you a devil so that we can live together for all of eternity if not even EIGHT pawns can turn you?!"

Issei chuckled but then rolled his eyes. It'd been amusing at first, now her worried ramblings were annoying. The draconic young man grunted and drew his new slave's attention.

"Just get on with it. We'll figure something out if it doesn't work."

Blushing at the sharp reprimand, Rias nods in agreement and steps forward nervously, biting her lower lip as she reaches out and presses the last pawn into Issei's chest. With all eight pawns inside of him, Issei finally felt something. There was a brief glow and then instinctively he knew that he was now a devil, the transformation having finally taken hold. But at the same time, Issei could feel something else. Raising his eyebrows, the young man realized that if he wished to, he could change back to human at the drop of a hat, rejecting Rias' evil pieces.

Issei did not tell his new 'King' this, though as he looked at Rias' shocked, overjoyed face, he saw that she was not changing her attitude now that she could technically claim ownership over him. Instead, the crimson haired devil fell to her knees and laid her head in his lap, looking up at him with loving and devoted eyes.

"It worked! Master it finally worked!"

Smirking, Issei nodded. Indeed it had. But already the draconic newly reincarnated devil was thinking about something else. He didn't know if it was the hell that lay within him now urging him on, but Issei suddenly had the overwhelming desire to 'finish' what he'd started with Rias. Grunting, Issei reached down and grabbed hold of her red hair, pulling her up off the ground and dragging her into his lap.

Rias yelped but then obeyed his unspoken command as best she could, crawling up into his lap and blinking owlishly at him. Issei responded by gripping her shoulders and turning her around so she was facing the other direction. Then he pulled her back against his chest, sliding his hands over her curvy voluptuous body and simply appreciating his new slave for a moment.

The crimson haired heiress moaned like the wanton whore he'd turned her into, before squealing a little as she felt his hardening shaft press up between her ass cheeks out of nowhere. Rias' eyes widened to the size of dinner plates and she looked back over her shoulder at Issei, biting her lower lip.

"A-ah, Master… I've never had it back there before."

Issei gave her a knowing look and Rias flushed scarlet. His nonverbal message was obvious and she had to admit, he was right. Before today, the sheltered girl had never had it ANYWHERE before. Issei had been the first man in her mouth and cunt. It actually seemed appropriate that he be the first man in her ass. Blushing furiously, Rias had the overwhelming urge to cover her face with her hands as Issei lifted her up and fitted his cock between her butt cheeks, up against her sphincter.

Then, he began to pull her down, slowly impaling her inch by inch on his rock hard meat rod. Rias was left gasping for air, eyes still unbelievably wide. Her butt clenched down as best it could, but even that tight amazing pressure didn't stop Issei's inexorable march against her back door. Ultimately, Issei was inside of her ass and about to fuck it and there was nothing Rias could do about it.

Though, the red head was not expecting to enjoy it as much as she began to. Only a few minutes after Issei had begun impaling her and Rias' gasps had become moans. She groaned as he began to thrust up inside of her asshole, but in the end all she felt was pleasure, both from the act of being taken anally, but also from being able to serve her master in this way. Rias Gremory moaned like a slut as Issei bounced her bubble butt up and down on his shaft, fucking her tight ass for all he was worth, which when it came to Issei, was quite a lot.

Still, she was insanely tight back there as he took her last virginity. Her butt muscles clenched down around his thrusting cock in a way her pussy simply couldn't replicate. As such, Issei's release came hard and fast and he grunted as he began to cum inside of Rias' ass. The crimson haired heiress' eyes widened as she felt his white hot sticky seed fill her bowels. And then, she was cumming too, her pussy juices spraying across the room and her eyes rolling up in her head as her face once again took on a perfect fucked senseless expression.

This was the scene that the rest of the Occult Research Club, the rest of Rias' peerage walked in on. Akeno, Kiba, and Koneko stared at the sight before them, wide eyed and taken aback. Even Akeno was left in a state of utter shock as she observed her long time friend's expression and naked heaving body, currently impaled on the cock of none other than Issei Hyoudou.

Rias' peerage had known that she was going after Issei at lunch today. They'd suspected that he might be a tough nut to crack for the beautiful crimson haired woman, and when neither he nor her had shown up to classes for the rest of the day, they'd written it off as Rias putting in the full amount of effort necessary to convince him to join the peerage.

None of them had expected this though. Their beloved King looked so utterly disgraceful, her ahegao face on full prominent display for all to see. And Issei? The brown haired boy shifted so that he could look out from behind Rias' naked twitching body at the newcomers. His eyes were rather apathetic and his face was expressionless. In response to being caught out like this with their King, Issei greeted his fellow peerage members in a rather simple way.

He raised two fingers up and waved them once. And then he said a single word, not even a true word, simply a syllable, a piece of slang meant to express casual greeting, even though this situation was anything but casual.

"Yo."

A moment later, the room exploded with shouting.
