High School DxD: Infinite Legacy

Chapter 1: Ophis's Plan

Venice, Italy, 19 Years before the Beginning of the Series

Sitting at a café by one of Venice's many rivers, surrounded by humans, was a very different individual. This individual had the appearance of a girl who couldn't have been any older than 10 years old, and was short enough that she was able to swing her legs back and forth as she sat in her chair. Her large eye were a neutral gray and her hair was black as night, as well as long enough that it reached down to her hips. Hidden by her hair, her ears had pointed tips, signifying that she was not human. Her outfit was that of a gothic Lolita.

This "young girl", as the humans who passed by her saw her as, was Ophis, the Infinite Dragon God and strongest dragon in existence.

Ophis sat at the café and watched humans live their lives around her. Some were enjoying coffee and bread, others were talking amongst friends, there was even a young couple that was enjoying a gondola ride while look lovingly into each other's eyes. Indeed, the actions that humans were able to take were many and varied in an iconic city such as this, and the general air seemed to be one of happiness and excitement.

She could not understand any of it.

Why did humans enjoy making such noise and acting with such energy? Perhaps, because their lives were so much shorter, they acted so much more energetically in their actions to compensate. Or maybe they were just naturally inclined to make so much noise. Depending on what they believed, humans were supposed to be descended from primates, after all. Then again, considering that Ophis desired silence above all else, that could be her own bias talking.

By now, you must be wondering why Ophis was even sitting there in the first place. Why would a being as powerful as the Ouroboros Dragon be sitting amongst humans when she desired to be amongst silence, much less at a place as noisy as a café? The answer, actually, was pretty simple. Ophis wasn't sitting amongst silence because she was unable to do so.

She actually had the perfect and most quiet place where Ophis could enjoy the silence she loved so much. The place was none other than the Dimensional Gap, the void between dimensions where the dragon goddess was born and lived for countless millennia. However, Ophis had, at one point in her life, left the Dimensional Gap behind and entered the rest of the dimensions.

When Ophis returned to her home, afterwards, she found that it had a new tenant.

A massive and truly mighty dragon that went by the name of Great Red had taken up residence in her home, and refused to leave it after coming to a place that was perfect for him to cause all the chaos he wished without destroying entire continents. Seeing as Great Red was also known as the "Apocalypse Dragon", then it is likely that such would indeed occur if he did his stunts anywhere else.

While having the freedom to act as he wished was good for Great Red, this left Ophis in a bind. Above all else was her desire to return to her home and reclaim that world of silence, but Great Red prevented her from that. And as much as she disliked it, neither she nor Great Red had the level of power needed to defeat one another. So, if Ophis was going to evict Great Red from the Dimensional Gap. How was Ophis going to get that kind of help? The answer to that was simple as well.

Ophis had decided that she was going to have a child.

Now, before this decision is balked at, let things be considered from Ophis's point of view. If she was going to gather enough powerful allies to defeat Great Red and force him from the Gap, then the forces that Ophis brought together needed to be exceptional in strength. From devils to angels to exceptional humans to other dragons, every person she recruited had to be strong and would help in her battle. And who would be more beneficial in a fight against Great Red than someone who shared her blood?

If Ophis were to have a child, than that child would receive her blood and all the power thereunto pertaining. Granted, that child would likely not reach the same level of power as herself, but he or she would still be a force to be reckoned with. And what's more, if she could find a strong enough person to be the child's other parent, then that child would have the other parent's strength as well and truly become formidable. So, Ophis had come to the conclusion that the best way to defeat Great Red was to have a child.

But that in turn begged the next question: who should she have the child with? Tilting her head back and ignoring the humans around her, Ophis closed her eyes as she thought further.

First, the smartest choice would be to decide what race of being she wanted her child to be half of. Her own sense of bias immediately turned her thoughts towards it being another dragon, which would in turn allow her to have a child that was a pure-blooded dragon. However, that thought was discarded, as while her child would have 100% dragon's blood, the only two dragons she could consider "worthy" of siring her child her the Two Heavenly Dragons, which were both perpetually stuck in their Sacred Gears. That ruled out the dragons.

Next, there were the Yokai to consider. It was not a bad suggestion, as having Yokai blood would enable her child to wield Youjutsu and eve, to a lesser degree, Senjutsu. Being able to wield the power of nature itself was definitely a major bonus. Not only that, but each race of Yokai had their own unique abilities, from the Kitsune's control of fire to the enhanced reflexes and senses of Nekomata. Unfortunately, there existed very few Yokai left in the world, and none of them at that current point in time had the power she desired for her child. So, no Yokai.

Humans were also considered on the basis that there had been many notable humans throughout history of great power, and possessed remarkable skills at bringing other beings together for a common purpose. If Ophis's child were to be born half-human, they had the chance of being a great leader and fighter. Not only that, but there was the very slight possbility that her child would be born with one of the greatest gifts God had given to humans: a Sacred Gear.

However, humans too were discarded as non-viable. While having a half-human child did means there was the possibility of all those benefits, there was no guarantee of it like the other races. And not only that, but the chances of her child getting a Sacred Gear were about one in a million. That was a gamble that Ophis was unwilling to take.

Now, Ophis considered the three largest of remaining races: Angels, Fallen Angels, and Devils. Angels was an instant no-go, as there was no way for her to convince any angel, male or female, to sire her child without having that Angel become Fallen in the process. That narrowed the field to Fallen Angels and Devils. Fallen Angles was not a bad idea, as there were certainly more than a few stronger beings within their ranks, their leader Azazel being a prime example.

Ophis hummed. Now, that was actually not a bad idea. If she were to manage to get into bed with Azazel and become impregnated via his seed, then her child with have the genetics of a twelve-winged Fallen Angel. That would in turn mean that her child would have access to the powers of using light as a weapon, as well as the intelligence that Azazel himself had displayed as leader of the Grigori throughout the centuries. The fact that Azazel was a known pervert could even mean that getting him to have sex with her would be easier.

That was honestly saying little, thought. While Azazel was a "ladies' man" and was reputed to have fallen because of his own lust in first place, that intelligence he had displayed meant that he was unlikely to be fooled into being seduced and would instead discover her intention before they even got into bed. And there was the fact that Azazel's pervertedness could possibly be passed down to her child.

Ophis shuddered at that. If there was one thing that her child would not be, it was a pervert.

Which meant that she now turned her thoughts to the last candidate. The Devils. Like the Fallen Angels, the Devils were a large faction and possessed several powerful beings. Heck, their entire system of government revolved around being led by four Devils of extreme power: the Maou. Each one of them were strong beings in their own right, and to have a child with one of them would make certain that her child would be as powerful as she envisioned.

Not only that, but the fact that there were four Devil leaders quadrupled her chances of having her desired child. Also, if her child had Devil blood, then there was a very significant bonus that he or she would have—the ability to use Evil Pieces and build a peerage. That thought actually caused her to release a small smile. Yes, the idea of her child growing to be a strong devil/dragon hybrid and building their own peerage was one that she liked a lot.

It was decided, then. Ophis would have a child with one of the four Maou.

But which Maou would she choose from? There was Serafall Leviathan, Ajuka Beelzebub, Sirzechs Lucifer, and Falbium Asmodeus. Perhaps it was because of the fact that Ophis had been in a female form for the past few centures, but she felt the desire to actually give birth to the child herself, rather than impregnate someone. That ruled out Serafall Leviathan. Falbium was also ruled out, as she had seen the man's almost inhuman sense of sloth and had no desire for her child to be such a slacker.

Ajuka was almost cast off for the same reason, but it had been shown that the Astaroth devil was dependable when needed. And his intelligence was also far above that of his peers for him to do something such as create the Evil Pieces themselves. Were she to seduce Ajuka as well, then she would also be in his home, which would the prime place for her to steal a set of Evil Pieces for her child to use in the future as well.

But, in the end, Ophis decided against seducing Ajuka as well, as the man's passion for inventing was sometimes even greater than his dedication to his job as Maou, which was not a trait she desired in her child. And even if she did not seduce Ajuka, she could still sneak into his estate and steal a set of pieces later. You would be amazed what being a true shapeshifter like herself enabled her to do.

Which mean that the field of candidates for the other parent of her child was narrowed down to one: Sirzechs Lucifer.

Ophis retained her smile at that. Out of all of the Maou, the former heir to the Gremory house was by far the most powerful of them. Not only that, but the Maou was known for his kindness and preference towards avoiding combat. That said, he would not hesitate if he needed to fight, and was very devoted to his family. Rumors were that when the Lord and Lady of the Gremory house told Sirzechs that they planned on giving him a sibling, he nearly blew a hole through an entire side of the Gremory Manor in excitement.

Even without the strength that Sirzechs possessed, he did possess a unique gift amongst the devils: the Power of Destruction. Granted to him by his mother's blood from the Bael clan, that ability alone allowed the Crimson Satan to take any matter, living or not, and completely disintegrate it to the point that not even dust remained. If Ophis's child were to have that power along with her own, then few would be able to match them once her child became skilled.

Of course, there was no guarantee that her child would get the Power of Destruction when it was only a quarter of the Bael clan's blood against her own. Either way, Sirzechs, by her estimation, was the prime candidate for fathering her child. And there was one last thing that made him the perfect candidate to seduce: Sirzechs Lucifer had a wife.

If it weren't already for the fact that the man completely loved his family, the fact that Sirzechs was married was the icing on the cake for choosing him. In order to get in bed with the Maou, all she needed to do was shapeshift to look like his wife, Grayfia Lucifuge, have sex with him, and it was done. It would need to be done at a time when Grayfia was not home, but it could be done regardless. Even better, she had no fear of acting out of character since Grayfia barely showed any more emotion than Ophis herself.

It was decided, then. In order to defeat Great Red, Ophis would disguise herself as Grayfia Lucifuge and have sex with Sirzechs Gremory in order to have a child. It was genius, if she were vain enough to say so.

Now, all she had to do was keep a spying eye on both Sirzechs and Grayfia to determine the best time to initiate her plan, and then get into the Maou's bed. And once that was done, she'd wait until she was ready to give birth, do so, and raise the child until it was ready to begin helping her with her plan to fight Great Red. She had been trying to get rid of the Apocalypse Dragon for centuries; she was willing to wait longer.

Though, raising the child did mean that she'd have to complete such tasks as feeding him or her, making sure that they were healthy, training them to become a powerful fighter, teaching them everything academic or not that they needed to grow up to be mature and intelligent…

Ophis blinked, and finally spoke aloud. "This… is going to be harder than I thought," she said.

Several weeks later

Ophis hummed as she stood in the air far above the Gremory Manor. After several weeks of observation, she had finally found a time when it would be best to execute her plan. In two days, the Lord and Lady of the Gremory House were going to be traveling from their estate to the lands belong to the Phenex house in order to work on the details of a marriage contract between the recently-born third son of Lord Phenex and the daughter that Lady Gremory was expecting to have.

When that happened, Sirzechs had assigned Grayfia to go along with his parents. Just because both the Lord and Lady were High-Class Devils and of greater prominence in society, that did not mean that there was no chance of either bandits attacking or tensions between the two Houses dissolving into something violent. Having the "Strongest Queen" with them would prevent either.

That, of course, meant that there would be at two weeks in which Sirzechs would be by himself at the Gremory Manor. Well, alones besides the house servants and what members of Sirzechs's own peerage were present.

Fourteen entire nights in which Ophis could disguise herself as Grayfia and enter the household, where she could seduce Sirzechs into sleeping with her and giving her the seed she needed to have a child. Of course, she would have to come up with an excuse as to why "Grayfia" was back earlier than planned, but that was a simple matter.

Getting into bed with Sirzechs was also simple, considering that Grayfia was his wife. The hard part would come in actually acting as if she enjoyed the actual intercourse needed. Despite her best efforts, it would appear that, whenever the married devils were copulating with one another, an array of spells and seals went up to ensure privacy between the two. Ophis could have broken through the array with ease, but that would have alerted Sirzechs and Grayfia and ruined her entire plan.

So, in addition to having never actually been sexually active with anyone before—she had never possessed any interest or need for such a thing—but she also had no idea whatsoever as to how Grayfia acted in bed. Was she still quiet and reserved, or was a switch flipped and the silverette became loud and expressive? Were the certain fetishes she had that they acted out, and what was she required to do if Sirzechs felt the desire to do so? What subtle parts of her personality would Ophis need to copy in order to fool the Crimson Satan?

That was the biggest obstacle to getting Sirzechs to have sex with her, and if she did not pull this off then her carefully thought-out plan would crumble like a house made of so many cards.

Well, she had two days to figure out. After that, the show would begin.

Fifteen days later

Under the cover of darkness, Ophis knocked on the front door to the Gremory Manor, fully transformed into 'Grayfia' and waiting with her hands clasped in front of her as she waited. Her facial features were perfectly schooled to match that of the silver-haired Queen's, completely blank and befitting that of the head maid of the house.

The door was quickly open by one of the lower maids, who squeaked in surprise at the sight of her. "G-Grayfia-sama! We weren't expecting you until tomorrow!" she exclaimed, hastily curtsying and bowing her head.

'Grayfia' nodded and inclined her head as well, before both of them stood straight. "Yes, I was bid by Zeoticus-sama and Venelana-sama to travel ahead of them and ensure that the manor was prepared for their return. Could you be so kind as to inform my husband of my early arrival while I inspect the household?" she asked.

The main quickly nodded and said "I-I'll inform Sirzechs-sama right away" before running off, still flustered by the unexpected return of her 'boss'. 'Grayfia' watched her go and waited until she had run around a corner before walking through the doorway, closing it behind her and continuing on. The halls of the Gremory Manor were just as vast as they appeared to be from the outside, with various portraits of exquisite paintins or past memory of the Gremory Clan adorning the walls.

The carpet was a red as vibrant as the family's signature hair, while the wall paper was maroon and adorned by flower vases and a mixture of candle lamps and electric lights. And if she were to move further towards the center of the mansion, 'Grayfia' was sure that she'd find their luxurious garden as well. Truly, the entire mansion screamed to the wealth of the Gremory Clan.

She was interrupted from her thought process by hearing a male voice bellow "Ah, Grayfia!" and turned around to see an absolute giant of a man walk towards her.

The man was nearly seven feet tall and possessed brown hair that fell down the sides of his head before it was pulled back into a ponytail that reached his shoulder blades, and a goatee of the same color. His eyes were a gray-green and he wore vest made of chain-mail over a black shirt and a black pants with a black belt over the vested with rounded rivets. The most noticeable feature, however, was the set of muscles on him that could take any professional bodybuilder and made them look positively flabby.

From the classical Anglo-Saxon garb and the muscles, 'Grayfia' deduced that this was Beowulf, the descendant of the original hero Beowulf and Sirzechs's Pawn. Incidentally, he was also among the Top 5 Most Powerful Pawns in the Underworld, and could certainly cause a ruckus if he figured out who she was.

Luckily, the giant Pawn didn't figure it out right away, and smiled at her before giving a quick bow. "I'll admit that I was surprised to hear that you were back early, but it's good to see you also the same. Did the Phenex Clan give you or the Lord and Lady any trouble?" he asked, leaning against a wall and crossing his arms.

'Grayfia' shook her head, saying "No, both the Lord and Lady of Phenex Horse were polite and cordial, as well as smart enough to keep their children from interfering with the negotiations. The marriage contract has been made official, so our business with the Phenex is done for the time being."

Beowulf nodded, not having any reason to not believe her. As it was, he smirked and said "Well, I do hope you're ready for when Sirzechs-sama finds out that you've made it back. Ever since you left, he's been moaning and groaning almost without stop about how much he misses his-"

"GRAY-CHAAAN!"

Beowulf laughed and 'Grayfia's' eyebrow twitched as she heard Sirzechs's voice. Less than a second later, the Satan himself rounded the corner of them hallway and launched himself at her, catching his 'wife' in a hug and spinning her around. "Oh, Gray-chan, it's so great to see you! These past few days have been torture without seeing your beautiful face! You know, I'm really starting to think that you enjoy making me suffer by going with my parents on trips like this just so you can see me pamper you when you get back and-"

'Grayfia' stopped Sirzechs mid-rant by pinching his cheek and adding a short burst of magic to make sure that it hurt even her 'husband'. "I believe that is enough, Sirzechs-sama," she stated, moving back and out of Sirzechs's arms.

Sirzechs's pouted and rubbed his cheek, trying and failing to get rid of the bright red mark that was now there. "So mean, Gray-chan…" he muttered, only then hearing Beowulf booming laughter as he watched the interaction between his King and Queen. Sirzechs quickly stood straight and dusted himself off at the realization that he had an audience, and said "Anyway, I have some paperwork to finish before I turn in for the night. Once you've finished everything that you need to, I'd be happy if you joined me."

Then he gave her another quick and, before he could be pinched again, walked off. Beowulf gave one more chuckle before excusing himself, saying that he was going to see if Enku, his fellow Pawn, was around for him to challenge to a spar.

That left 'Grayfia' alone, who looked around to make sure the coast was clear before raising her arm. A spectral snake lithered out from within her sleeve and landed on the ground, where it began bulging and growing larger. Once it was the same size as 'Grayfia', it began to gain color and solidify, resolving into a copy of Grayfia.

'Grayfia' looked at the copy and gestured to the halls towards the kitchens. "Ensure that all of the tasks that Grayfia would normally conduct are completed. I will go on ahead," she ordered.

The clone nodded and walked off, while 'Grayfia' walked towards where the bedroom for Sirzechs and his wife as located. Servants bade her welcome or bowed their heads as she went past. Eventually, she reached a set of double doors and walked through, seeing an office space that no doubt belonged to Sirzechs. It was a large, Victorian style desk made of dark wood with a put-out candle and a stack of papers in the 'out' bin.

'Grayfia' also took note of several pictures in frames around the desk. Upon looking, she saw that one of them was of Lord and Lady Gremory on their wedding day, the wedding days between Sirzechs and Grayfia, and one photo showing all four members of the family while Venelana's stomach showed a noticeable bulge, signifying that a new member of the family was soon to join the portrait.

Looking at another set of double doors, 'Grayfia' took a deep breath to prepare herself for the hardest part of her entire mission and began to disrobe. Once the French maid outfit was discarded and she was standing only in a sheet of sheer silver lingerie (that she had actually managed to sneak in and steal from Grayfia's wardrobe earlier in the week", she pushed open the doors and walked through.

Sirzechs had been looking forward to her arrival, as he was sitting up in bed clad only a pair of black boxers. He smiled at seeing his 'wife' in the set of bra and panties that he had bought her on her birthday—not that Ophis knew that. "You know, you really do look beautiful in that. It matches your hair," he said. 'Grayfia' put on a small smile at that and climbed onto bed, making sure that her chest bounced as she did to distract Sirzechs.

As predicted, his eyes were drawn to bouncing breasts, giving 'Grayfia' the time to use her magic conjure up a blindfold. "Sirzechs," she said, drawing his attention back to her face. Holding up the blindfold, she said "I had heard that being blindfolded while having sex increases the sensation you feel exponentially. I was wondering if you were willing to try it," she said.

While raising an eyebrow at the unexpected surprise, Sirzechs merely smiled amusedly. "Well, I can't say that the idea doesn't intrigue me. Okay, I'll give it a shot," he said. He took the blindfold and wrapped it over his eyes, making sure to knot it tightly. 'Grayfia' allowed herself a larger smile. Well, this would ensure that any facial expressions that she made that were out of character wouldn't be spotted. But before she could finalize the process to ensure she wouldn't have any trouble, she'd have to get Sirzechs to be even further… agreeable.

WARNING: Lemon begins here! Underage readers, skip to the next bold.

And so, in order to please him, she unhooked the bra holding her considerable assets back and grabbed Sirzechs's hands. Bringing them up to her chest, she let him squeeze them and he blinked behind the blindfold. "Wow, you were right, Now that I can't see, you're breasts feel even softer than usual. This is incredible," he said, gently kneading each one while occasionally flicking her nipples.

'Grayfia' could feel her transformed body begin to respond to the administrations, several centuries of being in bed having given Sirzechs a lot of experience in how to please a woman. Even though her expression did not change, 'Grayfia' gained a small dusting of pink on her cheeks from the pleasant sensation and move to straddle Sirzechs, giving her greater ease to further massage her chest.

She let him continue for a few more minutes before moving back, causing Sirzechs to frown. "Gray-chan? Where are you going?" he asked.

'Grayfia' chuckled and trailed her hands down her body, letting him know that she was still close by. "I thought it might be best to 'prepare' you before we got to the main course, my beloved," she said lovingly, while hooking her finger into the band of his boxers.

Sirzechs grinned and laid back, saying "Well, far be it from me to turn down such an offer from my loving wife."

'Grayfia' chose not to respond and simply removed his boxers, letting his already hardened member spring free. It appeared to be about six inches in length, which was above-average in length (upon preparing for this, Ophis had actually read an article stating that 5.2 inches was the average) and throbbing with desire. She wrapped her hand around her and Sirzechs hissed as the heat of his dick came into contact with the cool texture of her hand.

However, before things could begin, he suddenly sat up and called "Hold on a sec!" 'Grayfia' quickly looked up, fearing that she may have been caught, but Sirzechs simply clasped his hands together and released a pulse of magic. A menagerie of seals and written spells appeared along the floor, walls and ceiling before fading away, and Sirzechs leaned back. "There. Now we can enjoy ourselves in private."

'Grayfia' nodded and got to work. He could feel her begin to move her hand up and down, and while the feeling of getting a hand-job from his beautiful wife was incredible, he couldn't help but feel like something was… off… about her technique. What, exactly, he couldn't put his finger on, especially since it was starting to get a little hard to think from having his dick stroked, but it felt almost like the hand-job was more inexperienced than the ones he had received from Grayfia in the past.

As it was, it was still good enough that his pleasure overrode his confusion, and Sirzechs moaned when 'Grayfia' rubbed her thumb over the head. "Ah, Gray, that feels great," he said.

'Grayfia' hummed but said nothing, only quickening her pace while using her other hand to gently cup Sirzechs's nut-sack and roll them in her hand to increase his pleasure and hasten an orgasm.

Sirzechs moaned louder at that and began breathing heavily, a light sheen of sweat appearing on his forehead. 'Grayfia' also began channeling a light current of energy to her hands. The magic didn't serve any function other than to warm of her hands to also cause them to vibrate slightly, both of which compounded the pleasure she was delivering.

Under the combined assault of all these techniques, it wasn't long Sirzechs began leaking pre-cum and throbbing even harder, showing that his orgasm wasn't far behind. Seeing that, 'Grayfia leaned forward and extended her tongue, lightly licking the tip of her 'husband's' cock before sealing her lips around the head and humming.

"Oh, shit! Grayfia, you keep that up and I'll be undone in no time!" Sirzechs, bucking his hips slightly on instinct from the pleasure.

'That's the idea, Sirzechs Gremory,' 'Grayfia' thought, before taking him in even further. It wasn't only when he reached the back of her throat that she was forced to stop, unable to suppress her gag reflex. That, she noticed, caused Sirzechs to frown, and 'Grayfia' mentally grimaced. Apparently, being able to deep-throat Sirzechs was a skill that the real Grayfia did, in fact, possess. Just great.

Thankfully, she had managed to have gotten Sirzechs so worked even before putting him in her mouth that he was about to blow his load. For some reason, 'Grayfia' felt a sense of pride in that accomplishment, and also began swirling her tongue around what she could fit in her mouth.

After another minute of this treatment, Sirzechs groaned and propped himself on his elbows to look at her. "Gray-chan, I'm about to cum!" he called. 'Grayfia's' response was hummed even louder and channel a current of energy through her mouth muscles and to his dick, causing a sudden spike in pleasure that sent Sirzechs over the edge.

"Fuck!" he swore, and blew his load in his 'wife's' mouth while also bucking his hips and pushing his dick down her throat slightly. 'Grayfia' gagged slightly before being forced to swallow both his cock and his load lest she have her airways blocked. After several seconds, the steam of semen into her throat subsided and Grayfia pulled back. A strand of saliva hung between her lips and his dick before she swallowed the last of the load.

It tasted… salty. Not bad, necessarily, but salty. Interesting.

Refocusing on Sirzechs, she could see him leaning his head back and sighing in bliss as he came back down from the height of his orgasm, which the lack of sight only made greater. Really, this was a fantastic idea that his 'wife' came up with.

Knowing that now was the time to initiate the final stage of her plan, 'Grayfia' conjured a pair of earmuffs and said "Sirzechs-kun."

The now-highly relaxed Satan smiled up at her. "Yes, my love?" he responded.

Making sure that her voice was understandable, she said "While I was looking into how losing one's sight can increase sensitivity, I also read that being deprived of hearing can increase the pleasure someone feels even further. Would you be willing to try that?"

To her surprise, however, Sirzechs pouted. "What? But you know that I love hearing you moan when we really get into, Gray-chan," he stated, not as pleased about this suggestion as the first one.

But 'Grayfia' managed to quickly think of a counter to this, and said "But this is something that I want to try, Zechsy-kun. After what I just did, won't you trust me on this?" She made sure that the pout she put on her could even be heard in her tone. The combination of that, the affectionate nickname that Grayfia only used on him less than a few times as well as the lethargy from his last orgasm were what convinced him to give in.

"Well… alright, Gray-chan. I'll decide to trust you on this," he said. Then he cracked a smirk. "Just don't get too kinky and tie me to the bed while I'm blind and deaf," he added.

'Grayfia' chuckled and put the earmuffs in Sirzechs's hands. He put them and made sure that they were smug. Snapping his fingers a few times next to either side of his head to ensure that he couldn't hear, he gave her a thumbs-up once he was sure and laid back. 'Grayfia' smirked victoriously at that. 'Now, I've got you right where I want you,' she thought, before stripping herself of her panties and climbing onto Sirzechs's lap.

Notice: Lemon is over. Underage readers, carry on.

At that same moment…

Beowulf huffed as he walked through the halls, exhausted and yet please at the same time. He had managed to find Enku and the two of them had duked it out some distance away from the manor. It was a match between Enku's speed and agility against Beowulf's raw strength and endurance. It was a good match, even though he felt slightly depressed about his teammates still treating him a lackey.

It was serious blew to his self-esteem, and it was only the fact that he had managed to put Enku in a headlock and force him to submit that kept the end of his day bright.

He was interrupted from his thoughts by a knock from the front door. Grunting curiously and seeing that there was no maid or other servant around to get it, he walked forward pulled open the door himself.

Standing on the other side of the door was none other than Grayfia, who, while raising an eyebrow at Beowulf being the one to answer the door, chose not to question and merely bowed her head. "Beowulf-san, it is a pleasure to see you once more," she said cordially.

Beowulf blinked in surprise. Completely forgetting his usual manners, he bluntly asked "Um… Grayfia? What are you doing?"

Interpreting the question as one about why she had arrived early, Grayfia said "I was sent ahead by the Lord and Lady Gremory to ensure that the manor was prepared for their return tomorrow. I apologize for having made it back at such a late hour, but I thought it better than simply waiting until morning."

Tilting his head to the side, Beowulf said "Err, that's not quite what I meant, Grayfia-san. What I'm asking is why you're acting like you just got here."

Now Grayfia was confused as well. She vocalized that, saying "What are you talking about, Beowulf-san? I'm acting like I just arrived because I have only just arrived."

Beowulf's next words, however, chilled her to bone even with all her power over ice. "But that's impossible. I just saw you talking with Sirzechs inside the manner a little while ago!"

Grayfia's eyes widened in shock before narrowing. "Then it would appear that we have an intruder in the manor," she declared. Beowulf's eyes widened in both shock and realization. However, now that he knew what had happened, he was able to process things much more quickly, and his expression became determined.

"I'll raise the alarm and inform the other members of the house. Grayfia-san, you go on ahead. If this imposter was strong enough to fool even Sirzechs and the rest of us, then he'll need your help to beat them," he said, before rushing off to do as he just said.

Grayfia nodded and ran through the front door, not even closing it behind her as she raced for her and her husband's bedroom. Concern for his wellbeing warred with anger that he could be duped into thinking that someone else was her as she got closer, making her wonder what she would do to her husband once the imposter was taken care of.

After several moments, she reached the door to Sirzech's office and pushed through, sensing that the privacy spells that they had set up were active. That could only mean that her husband was indeed in the bedroom and was having sex with the manor's intruder.

Not willing to wait and take a subtler approach, Grayfia charged up her energies until a silver glow surrounded her, and she flung both hands at the doors. A wave of sub-zero wind and solid mini-glaciers blasted the doors and the privacy spells struggled to hold up. After a few seconds, they feel and the door swung open.

Just in time for her to hear her husband called "Gray-chan! I'm cumming!"

Grayfia stared at the scene before her. Her husband was lying on his back with a blindfold on and earmuffs blocking his hearing, while a woman that looked exactly like her was seated in his lap and being came inside without a condom or, if she had to guess, any kind of contraceptive either.

The sound of the doors opening caused 'Grayfia' to whip her head, and her eyes widened in shock at seeing the real Grayfia right there. Before the real one could react, the fake Grayfia used a blast of energy to launch herself towards the ceiling, where the air tore itself apart and created a gaping hole that led to who-knows-where.

"Oh, no you don't!" Grayfia yelled, and jumped into the air after the imposter. Only for her to be tackled from behind and knocked down by a third Grayfia, one that morphed into a spectral snake immediately after and flew up to the imposter. She caught it and flew through the portal with a victorious smirk on her face, closing the hole in reality the moment she passed through.

Grayfia stared for a moment in shock, not processing what had just happened for two entire seconds. Then it went through. Not only had some imposter managed to seduce her husband into their own bed, but they had escaped and gotten away with it too.

"What the heck is going on?" Sirzechs asked, having sensed something was wrong the moment the fake Grayfia launched herself off of him and had removed both the earmuffs and blindfold to see what was wrong. Now, instead of sitting on his lap, naked, his wife was getting up from being on the floor and was back in her full Franch maid outfit. "Erm… Gray-chan? What exactly is happening?" he questioned.

At the sound of her husband's voice, Grayfia faced him and her anger at him overcame her desire for his safety. It also let her decide what to do with and provided an outlet at her anger for the imposter having gotten away.

Sirzechs watched in growing apprehension as the upper half of Grayfia's face became shadowed and her eyes glowed a scary ice-blue. The air temperature of the room plummeted until Sirzechs could see his breath and felt goosebumps all over his naked body. Frost also began to spread across the carpet from where she was standing. Something that only happened when she was well and truly pissed off.

"Sirzechs…" she growled.

Then all he knew was cold and pain.

"AAAAAAAAHHHHH!"

One week later…

Sitting back in her chair at the café in Venice, Ophis grinned and sipped on a cup of tea. The plan had gone off perfectly. Now she had the seed of the strongest devil alive within her, and within nine months that seed would cause her to give birth to possibly the strongest being alive since herself and Great Red. The perfect person to help her complete her dreams.

To make to even better, she knew that none of the Underworld's forces were going to come after her. The higher-ups in the devil society would no doubt have a shit-fit if the fact that an unknown intruder was able to infiltrate the heart of Gremory territory was made available to the public. So, the entire incident was being covered-up and anyone who knew anything was sworn to silence.

Best of all, Sirzechs, Grayfia or any of Sirzechs's peerage were unable to come after her, due to Grayfia being too angered to watch such an order and Sirzechs being unable to issue any orders at all for a while. Why was that?

Apparently, the Crimson Satan was bedridden for the foreseeable future with a sudden, mysterious and very intense case of frostbite.

On his testicles.

Anyway, after having escaped from the Underworld, she had changed from the form of Grayfia to an older version of her Lolita form. Besides being taller and with larger breasts and hips than before, her facial features were more mature than before and her hair reached the back of her knees instead of her hips.

She had also switched out her Gothic dress for sleeveless black Victorian dress with frills on the front of the gown, black leather corset and black gloves that covered her arms all the way up to her elbows. The idea for the entire transformation had been for her body to be perfect for the birthing and nursing of a child would now occur within nine months, and she felt as if she succeeded.

Such was her satisfaction over what she had done that Ophis even let out a small laugh. Things had gone perfectly, and now she was ready to take the first step needed to raising the child who would become not just her child, but most powerful champion, her immortal warrior and maybe even be next Dragon God.

Yes, she would raise this child to be her progeny, her Infinite Legacy.

Well, there you have it. I hope you all enjoyed both this first chapter the lemon in it, which was actually the first lemon I ever wrote. Let me know (without flames, please!) how I did on that front, even with the situation being as unusual as it was.

However, let it be said that this story is NOT part of the set of active stories I have on rotation. What does this mean? It emans that this fic does not have a time after any other story when it will be updated, and instead only when my muse strikes me with inspiration for it.

Now that that's settled, let it be said that this fic, in true DxD fashion, will have a harem. Two harmes, to be exact. I'll be having one for Ophis's son—Deiru Ouroboros—and one for Issei. Both harems will start out with a maximum of five girls, but that may increase in the future depending on if I believe I can handle it and how the plot progresses. So if there are any girls you want to see with either Issei or Deiru, let me know in the review box and I will take your opinions into account!

Please review! If you flame me then Bruce Lee will smash you with his nunchaku. (I'm just kidding… or am I?)
