Like usual lewd sounds echoed throughout the Emiya like it usually did, then everyone was home. Though the sound of flesh slapping against flesh, moaning and cum splattering against the walls as I was the one tasked with watching over the girls while Shirou and Taiga were out being sociable.
And watching over them meant just having the hyper sized futa's filling up my holes with bathtubs worth of spunk, and of course over the last two weeks as they grew to maturity about what would equal fifteen their cocks had become even more massive and now stood a full foot above their heads then they lifted them up as due to their size they buckled under the force of gravity and mostly just laid on the floor in the cum they had fired from their cocks. Added by my own shots and Shirou.
With how much we came practically all the time, we simply no longer bothered with cleaning the place up after the first three days, and now the only part of the estate that wasn't covered in thick layers of spunk was the kitchen. The only reason no one complained about the smell of cum and sounds was due to the bounded field I had created around the Emiya Household.
And of course, with how sexually active my girls were, they had managed to knock me up not even a day after they had been born themselves. I still remembered waking up to seeing Mia and Dia fucking my lower holes.
Not like I was the only pregnant ones as their stomach was bulging to with the babies that Shirou had put in them as he had not been able to resist their multi oppai loli advances, then they could be qualified in that category. For they very much wanted to have daddy pop their cherries before they lost control and impregnated each other.
And as time passed through day, the girls really took a break from the pleasure of fucking mommy Iris' body and riding her cock.
The only time a genuine break happened was then there was lunch, but even Mia and Dia were utterly sexually active as they milked their lactating breasts into their glass to drink each other milk or just latched onto mu thick nipples that leaked down my white fur making it rather hard to see.
And like usual Shirou and Taiga came home to the hormone-filled air becoming instantly horny, I heard the telltale sound of Shirou's pants ripping as cock became fully erect in the span of seconds. I oh so loved how Shirou's body was developing on its path towards futahood, his waist becoming narrower, hips flaring butt becoming larger and softer, and he even had fully developed a-cup breasts now. I would call him a woman now or she, but he still lacked a slit that could be fucked and workable womb that could be impregnated.
But that was probably going to all change today.
The two walked into the living room the girls were taking turns fucking my pussy now while one watch tv while jerking her cock.
Shirou had ditched his ruined pants and worked his growing breeder hips towards us, while Taiga was still dressed in clothes but drenched as her milk and pussy juice had soaked her clothes.
"Good day at school?" I asked as I flipped around while Mia continued to fuck me, and I laid on my breasts and cock in the ocean of cum we lived in.
And it was so lovely dirty and lewd in fucking loved it as I could still feel the living sperm swimming around seeking fertile eggs, as that was how virile we were now.
"It was fine though Tohsaka was getting rather pushy about something, and Shinji has been acting weird lately, I think he is attracted to me now and doesn't know how to deal with it." Sometimes I forgot that Shirou went to middle School with Rin; I didn't know if that was canon or not, but it was apparently a thing here.
"He is probably going to get even more confused, then you get a set of proper knockers like me, Taiga and the girls," I said with a smirk as he blushed his hand going up to his developing tits. His hard nipples poking through his shirt, showing off his expanded areola.
"Well, from what you've explained to me about magic she probably sense Iris on you," Taiga suggested letting out a moan as Mia showed her cock into the place that had birthed her, though she would not have chance to knock her mother up anytime soon as Shirou had already claimed her next egg.
Hmm, I should probably introduce myself to Second Owner soon, I wonder if the little pubescent girl will enjoy a few heirs in her womb. I thought, and the desire to impregnate the tsundere made cum a little, a liter splattering against my tits and stomach.
"Though before we have dinner, I do have something to tell all four of you," I said with smirk as I changed my position pulling Dia out of my cunt my daughter letting out a sad whimper as it was exposed to the air but quickly moaned as I dropped it into the cum drenched flooring.
"And that is?" Shirou asked.
"Oh, it should be easy to guess I have managed to reach a point where I can evolve again," I answered with a smirk.
"Really?" That's great I wonder how much you're going to change this time? Do you think more human-looking that you already are? Something closer to our girls?" Taiga asked clapping her hands together. She had definitely changed since Shirou and I had first raped her all those months ago. And it had been rape as eyes becoming hearts did not change the fact it had been rape. Not that even Shirou or I cared as he had seen it as a case of helping instead of hurting. And I did feel the desire to go out and 'defile' some new women with my massive cocks.
"Maybe I don't actually know, as m changes before had been surprising to me too," At those words I let the change happen and my body glowed bright again just like before, and it quickly died down, and I could feel the sheer power that I now possessed.
I was a 'Fenrir' now a Divine Beast/Almost Spirit, and I was one transformation away from basically full-on Slaaneshood.
"Was that it, you didn't change except for all of your tits growing one breast size," Taiga commented as Mia emptied outside of her, her stomach swelling with cum as most that could not be contained leaked out onto the floor the sea rising ever so slightly.
"You can't sense it mommy, but we can and mommy Iris is much stronger now," Mia said as she pulled out her cock it flopping to the ground.
"Yep, our dear is right, Taiga I am so much stronger now magic wise and I can do a lot fo stuff I couldn't do before.
"What can you do now?" Shirou asked as he sat down on the cum his cock throbbing with need.
"I can turn you into a futa instantly now, I can make you just like me Shirou and you too Taiga I can make you just like our daughter, make you into Monster Girls," I said. "Do you want that Shirou? Do you want to become a well-hung Monster Futa like us? To have a womb that will birth out more daughters every single month?" I asked as I jerked Shirou off.
"Yes, yes, I want that Iris I've been dreaming out about becoming just lie you I want to feel the pleasure you do. A pussy to make you and others happy. And I want to stay with you for as long as possible," Shirou said with a tone full of love for, for he truly loved me and could not see a day without me in it.
Guess I had become the main heroine of this Route suck it everyone else.
"I would like it too, I want a big fat dick and more breasts, I want to nurse more children and not just my naughty students," Taiga responded as she followed up on Shirou's words.
"If that is what you want," I said with a gentle smile on my lips as I reached out for Taiga with my other hand and channeled Miasma into them transforming them into Futa Monster Girl like myself.
Which ones I didn't know as the Miasma would change them to what fits them.
Taiga groaned as I saw her blouse and shirt swell as sprouted more breasts beneath her original ones gaining rows just like the girls and me. They continued to grow ripping apart the garment and meeting the free air. And the same happened to her pants as a massive cock grew from her crotch with a furry sack to match the spinny red cat cock that Taiga now had cum spuritn from the tip and onto my face. And on top of her ears grew a pair of cat ears, along with a tail from her spine.
Taiga had become a catgirl of the Tiger variety, I had honestly expected Jaguar.
As for Shirou, his body changed the most, becoming fully woman as I smelt a slit forming and pussy juices dripping from behind her slightly growing ballsack. Her cock grew the most surging up to meet her face as it changed from a human one into an animal cock of the reptilian variety getting stuck in between the now-massive breasts that had an actual natural sag to them, unlike the pointy breasts Taiga and me had.
And now what Shirou had become was even more apparent as a scaly tail, grew from her spine, more scale growing over various parts of her body mostly arms and legs as pair of leathery wings sprouted from her back and horns grew out of the side of her head.
Shirou had become a Dragon girl and it was probably because of Avalon's influence that I had happened, like it wanted a perfect mate for Arturia.
But the King of Knights would have to wait as I tackled Shirou to the ground and immediate thrusted into her new pussy to bred it like I had promised her.
"Ah, fuck Iris fuck me, fuck me harder yes, thrust your cock into my new pussy," Shirou screamed as she blew out a few flames from her mouth. All the while Taiga was having fun with the girls.
I loved it, I loved this sexually charged and always ready to fuck family of ours and I couldn't wait to expand it.
But first breeding Shirou and then dealing with a certain Evil God to boost myself quickly to Slaaneshood.
