The Greater Grail.

The ultimate creation of the Einzbern family made utilizing the magic circuits of Justeaze von Einzbern and the Rheingold to serve as the Foundation of the Heaven's Feel ritual, also known as the Holy Grail War.

All for the sake of obtaining a fully realized Third Magic.

And it was something to be awed at, and I would be if I was actually capable of seeing it as it was three years before the war started and it hadn't manifested into reality yet.

Though that didn't mean it didn't exist metaphysical and could no be interacted with. That was why I was down in the dank depths of the cavern beneath Ryuudou Temple.

With my new found form, I have finally had the strength to devour the curses within the Grail and convert it into Miasma for me to evolve to my final form and become a full-on god of lewdness and lust.

And I still didn't know why the counterforce hadn't made any moves against me to try and force me to the Reverse Side. Or it knew what I planning and knew I wouldn't stay around for much longer and say what I was going to do to the city as an acceptable loss.

And for that plan, I did need the would be soon purified Grail and have the grail war happen in three years, as that would give me plenty of time to figure out my full capabilities.

"Now how to go about this," I muttered as I walked over to the center of the hidden magical circle that served as the Foundation to manifesting the Greater Grail. My erect cock leaking cum onto the ground as I walked, and my breasts did the same with sweet milk that was meant for the child in my stomach, that would soon be born and it would happen a second after I evolved as then I had yesterday my stomach had swelled from half to almost ready for birthing.

My magical senses of those on the level of a divine reached out to connect with the Greater Grail, and the fact I had already consumed some leftover curses left by Angra Mainyu I already knew what his presence felt like, so it didn't take me long to find the hidden chalice filled with curses of a billion different kind. Not that it mattered to me as I began to devouring summing through the now altered magic circle.

As it drained out the curses and converted it into Miasma for my body to absorb and it was pure bliss, my tongue hung out of my maw like the canine I was, as I just let my body relax to let out my fluids. It sunk into the circle that connected me to the Greater Grail, and the leylines of Fuyuki City as I basically re-tainted the Grail with my own power and the Leylines.

Well then I had said purify the Grail, I just meant not having it turn into a bomb of cursed fire, and mud then used. And I did the leylines to infect the people with excess Miasma and my sinful powers though it was just to set up a foundation to make it easier for myself for then I became a god. It was all based on the fact that Medea. Had been able to drain mana from people through the Leylines. So it stood to reason that you could do the opposite, namely put something into a human through a leyline.

So basically, I was going to put a curse on the entire place that would change this city into a den of lewdness. After it had been placed, it wouldn't take long for people to lose their morals and just start fucking each other, sons and mothers. Fathers and daughters, brother and sisters. Female dogs presenting them to their own like I had, and owners giving themselves to their male dogs to get knocked up with a bunch of puppies. And the more they indulged, the quicker they would turn into animal hybrids.

It was all going to turn fetishly awesome soon enough, the before the changes started to happen I had to do a few conquests myself to give to Shirou, so that his, sorry her harem would be complete.

I continued to suck the mud out of the Grail, and finally, then it was about to be empty. I found what I had been looking for. The souls of Avenger, Justeaze, and Irisiviel. Though they weren't really three separate ones anymore, rather three souls that had somehow fused into one due to the bizarre conditions inside of the Grail itself.

But I already knew what to do with it, I took the fused soul and instead of converting it into Miasma. I instead guided the soul into my womb and into the egg that I had put in stasis, while allowing its twin to grow, but then I evolved its development would speed up to where I was ready to birth this being. I could already feel the egg dividing and developing into a proper fetus.

And soon after, I felt myself hit the threshold as I absorbed the last of the mud.

"AHH," I moaned as evolved into my final form and became a prober god of sex, animals, and transformation. My milk exploded out of my tits in thick cream streams as I orgasmed my canine cock pulsating over and over again as I let loose a river of cum that filled the cavern. My vision went blank as I used my newfound power to just refill my balls over again to just simply flood the place.

"That, that was the best," I moaned as I milked my breasts as I stood knee-high in sexual fluids. "And now out with you dears oh how you have grown inside mommy," I moaned as I patted my massive belly as I felt my water break. From the looks of it, both of them were going to be born as adults.

My cervix and vaginal walls expanded as they were forced out me, and were immediately baptized by my cum.

I turned around to see my two daughters on their hands and knees as they laid my sea of cum. The image was so ridiculously lovely; it made me hard again.

"You, you ruined everything, and now I can't bring about the salvation of-." Justeaze's rant (cause that was her name was as she resembled her the most and seemingly was the central personality.) Was cut off as she was mounted by her twin sister, who looked precisely like her mother, Mia. Though unlike her, she did, in fact, possess a canine cock of her own.

Which she was thrusting in and out Justeaze's pussy at a vigorous pace.

"Now, now don't be like that sister, it doesn't matter now just submit to mother and the pleasure," Ria spoke as stroked her sister's cock it spurting out thick robes of semen that coated her tits as they added to the masturbation of her dick.

"Yes, you should listen to your sister Justeaze. While we can't give it to everyone on earth, we can bring pleasurable salvation to everyone in this city," I said as I thrusted my dick into her mouth, making her choke. "Now, now dear, like your sister said, embrace the pleasure." I used my powers to increase her sensitivity so that she came with every single movement.

"Oh sis you're clenching around me so hard, do you want to have my baby? Yes, do, don't you want all my baby's, don't you cause you're getting them now?" Ria shouted as I could her cum into her newborn sister, making her stomach swell up. Instantly knocking her up.

"Ria dear, don't wreck your sister too hard. She needs to be able to walk home," I playfully scolded her. Though I was mostly to place for her current orgasmic face with the whole sensitivity increase.

"Sorry, mommy," She apologized as she pulled out her sister, and I did the same, and Justeaze was barely able to stand.

"Now let's go home, you two, for I am sure your other family members would to met you all," I said as I went to pick up Justeaze, her mind was stilled a bit muddy after the rapid orgasms she had experienced.

The three of us left the cavern, and now I just had to wait three years until the Grail was ready. But I thought that I could easily get time to pass in the meantime. For I would never get tired of sex.
