I didn't know what had really happened; one moment, I had been biking, and the next, I was…

Memories fired through my head, and I…

Have I just been Isekai'd by Truck-Kun? I thought to myself.

Iskai'd into the much younger body of… Peter Parker.

"Oh," I said as I got out of my bed and looked at the window, where I saw the reflection of Peter Paker's ten-year-old body. "Well, I guess, I am now."

That was all I really needed to say; I didn't know if I could be a hero like the older Peter would have been, but I would certainly try.

Thankfully, it seemed I still had years to prepare for then the Spider-bite happened.

"Why are you being so loud, Peter," I heard a voice say, and I looked over to the other side of the room, where a figure sat up, the sheets falling down.

And he was quickly blasted with memories, and Peter knew that he was in a very different Marvel Universe as he stared at the inverted nipples that adorned Peni's huge braless breasts as she wiped sleep from her eyes.

Peni Parker.

Daughter of Aunt May and Uncle Ben(Who was already gone, the thought, sending a stab of hurt through my heart), and even at thirteen years of age, she had already been hit by the puberty fairy, turning her into the quiet the shortstack.

"Sorry," I apologized. "Just had a weird dream. Though the alarm is about to go off, so you might as well get up." I said as I looked at the alarm that read 6:27

"I guess," She said as she, too, got out of bed, and I got a full view of that large voluptuous ass of his and her thick thighs.

And according to my memories, it was a sight that Peter had been used to and not thought much of, really. Now however, I had the memories of an adult person who had gone through puberty and knew that her body was sin, and it was only thanks to my current lack of hormones that I wasn't sporting a boner at Peni's body as she bent over to look through a drawer for underwear revealing that she slept entirely naked her pussy lips on display as she dressed herself, and I started doing so as well.

I was dressed in jeans and a t-shirt, while Peni wore her school uniform that stretched around her almost head-sized breasts, while her skirt could barely cover most of her fat ass. As she went to a private middle school that fit her extremely high IQ.

We went downstairs, and there, sitting at the kitchen table, sat Aunt May, and she was very much so hot, Aunt May.

As she was in a pair of jeans and a braless tank top(with nipples tenting the cloth), which showed off her tummy and that clearly announced where Peni had gotten her curves from, and while she wasn't as big as the shortstack, it was clear to see that it was her genes that had allowed her to get so big. Though colorwise, Peni had gotten her black and brown eyes from Uncle Ben. As Aunt May had short, spiky brown hair and blue eyes.

"Morning, you two," Aunt May greeted us as she drank her coffee.

"Morning, Mom."

"Morning, Aunt May." I greeted her as we found our cereal and milk.

And from there, we engaged in our usual morning talk as we prepared for school and Aunt May prepared for work.

After which we left our house and stepped out into the streets of the City we lived in, and there I looked out to see the skyline of New York City, a bit more advanced one than I was used to as it was the Home of Stark Industries, Pym Tech, The Future Foundation, and others.

I got on the bus with all the other kids, and sat right next to the person I remembered as being my childhood friend the second I laid my eyes on her.

Cindy Moon.

"Morning, Pete."

"Morning Cindy," I greeted back as I took my seat.

"So you ready for the trip today?" She asked.

"Trip," I asked.

Cindy raised an eyebrow. "You don't remember? We are supposed to have a class trip to Oscorp today."

"…That was today?" I asked, while I slightly panicked internally, wasn't this a little bit to early.

"Yeah, it is today," Cindy repeated.

"I thought it was later." It should be later unless things had suddenly accelerated, or… if anything even happened because I now remembered that there did exist Spider-themed heroes already, Spider-Woman, the Arachne, Spider-Girl, Spinneret, and Arana already existed, so was to say I would actually become Spider-Man?

"Well, it is today, Numb-Numb," Cindy teased, and I just sighed as I made myself comfortable; either things would happen or they would not.

I couldn't really guarantee things.

"Oscorp is one of the many companies that are pioneering green solutions and repairing the environmental damage that has happened to our beautiful world," The guide said as we were giving the public tour of the laboratories and exhibits that showed off the stuff they were making. "Everything from Medicine, defense, computers, tools for construction, agriculture, and genetic engineering."

And the stuff they showed was interesting, but sadly the finer details went over my, as I seemed to not be that kind of Peter. Unlike my Cousin, my general intelligence was the same as it had been in my previous life.

And I was fine with that.

The tour continued, and we were told about more about the company and what they did for the world with Willi-Sorry, Norman Osborn at the helm.

"They really think they are super important, don't they?" Cindy whispered as we walked with the rest of the class.

"Yeah, I am pretty sure that Stark does more now that they stopped doing weapons," I said, for if what the news said were true, Oscorp still engaged in weapons dealing.

"Yeah," Cindy simply said as we were let into the genetics research hall.

"Here, children, we do research into Gnetics and Crisper." The guide said. "Have any of you heard what crisper is?"

I raised a hand when none of the others did.

"Yes, you young man," The Guide said.

"I heard from the TV it's the thing that allows you to change DNA," I responded like a ten-year-old that watched way to many science programs, and Peter had watched a lot of science programs.

"That is correct," The guide replied. "Crisper is the method to edit the DNA of all living creatures and is the solution to many diseases we have been testing with various animal DNA to see if some of their abilities can be given to another animal. Take these spiders over here; we have tried to find ways to manipulate their DNA so that they can produce stronger web-"

The guide was cut off as the sound of glass breaking was heard, and we all quickly looked to see the blue and red figure of Spider-Woman come flying through the window, which was quickly followed up by eight clawed tentacles as Doctor Octopus entered; the female mad scientist clad in her green suit and googles as she followed heroine she had thrown.

And then panic ensued as both adults and children started screaming and running, as the entire place was thrown into chaos, and before I knew it, both Cindy and I were hiding behind one of the public exhibits.

"I always wanted to see a Spider-Woman fight, but not this up close," Cindy muttered as the fight started to pick up as we heard Spider-Woman quip at Doc Ock.

"Same. This isn't really fun when you are actually caught in the midst of a super fight," I responded, though I did wonder if Spider-Woman had caught Doc Ock, trying to break into Oscorp or it had been another thing and their fight had simply brought them-

Crash!

The sound of more breaking glass reached our ears, and this time, it was right above us, glass shards falling down on the ground and around us, and we immediately raised our arms to cover our heads and bodies as we balled up as much as possible.

"Cindy, are you okay?" I asked as I turned to look at her and…

"Kyah!" Cindy screamed, and I saw the Asian girl smack smack something on her hand. And before I could ask, I felt a sting of pain on the back of my hand, and I quickly pulled down, and there I saw it sticking its fang into my hand was: a red and blue spider of a rather large size.

And quickly smacked it dead as my body reacted out of pure instinct.

I guess it would happen early… way early.

"Pete…?" I heard the voice of Cindy ask, and I looked over to my friend, where she was currently rubbing the area where she had been biten. "Are we going to be okay?"

"I think so; I don't think they would have used dangerous spiders," I said as I rubbed my own spot. "Just press it out a little."

"Hmm, okay," Cindy said as she gave the bite mark a little squeeze, pumping out a little bit of blood. "…I think the fight is over."

And… yeah, I couldn't hear the sound of punching anymore or Spider-Woman mocking the villain, and I looked around the corner to see that, yeah, both of them were gone, and I could now actually hear the sound of sirens.

"Yeah, I think so too," I said as I got up on my feet. "Let's go and find our class." I held out my hand for her.

"Yeah, let's go and do that," Cindy replied as she took it, I helped her on her feet and to avoid the glass that was on the floor.

And as we walked, I couldn't help but feel a throbbing feeling in my right hand, and I knew that whatever destiny was in store for the two of us had just been kickstarted way earlier than I thought it would be.

"Peter!" Peni shouted the second that the door to our home opened up, as Aunt May had come and picked me up at Oscorp, and quickly driven up home. "I saw the news, and I got so worried." The shortstack babbled as she gave me a bear hug, her large breasts pressing against my body.

"Don't worry, I am fine," I said, though I was starting to think that would change pretty soon as I could feel my head starting to get a little sluggish. "Didn't get hurt at all."

"Are you sure? Because you are looking a little red in the face," Peni said as she went and touched my forehead. "Mom! Better is really hot."

"What?" May asked as she quickly replaced Peni's hand with her own. "Peter, you're burning up."

"Wha? But I am feeling fine…" I responded as my words started to get sluggish and why was the entry starting to spin?

"Peter!"

The thread of the Web of Life moved as it imbued two Spiders with power, guiding the change of DNA to what would be most suitable for them, enhancing their bodies based on the Spider-hybrid Crisper Virus, and their gender.

May Parker was a woman who loved her family; she loved her late husband, loved her daughter, she loved her sisters, she loved her nephew… her Father.

Yes… Father

For her full name was Mayday Parker, and she was a Spider that was from the future, from an entirely different world even.

As it taken her a bit to realize that she and her sisters had not just arrived fifty years in the past from her point of view, but fifty years in the past in a completely different universe as it had not clicked that the man she had fallen in love, Benjamin Parker, was that Benjamin Parker, it only really clicking when her sister in law said that she was pregnant and that they were going to name him Peter.

They could be a little bit dense.

But that had also leading to complicated emotions resurging when she had held her baby Father in her arms, who had when went onto suckle on her milk-filled breasts. Then his Mother ran empty as he was hungry…

Old feelings had come back up from that, but she had thought she could bury them.

And then Richard and Mary had died, leaving her and Benjamin to raise him for the first five years of his life alongside Peni…

And then Benjamin had died protecting them from Cletus fucking Cassidy while she had been out being Spider-Woman. Resulting in the death of both men, with the silver lining being Carnage wouldn't be an issue in this universe(hopefully), but thankfully, Annie and April had been helping out over the last five years.

Her sisters were the best.

Though right now, she was concerned about Peter, the boy who would one day make a version of her, though considering Mary Jane was a Third Year, High School Girl living next door who sometimes babysat Peter and Penni… This world's version of her might have to be made with Cindy instead.

And as for why she was concrend about Peter? Well, the boy was currently running a high fever, so she had brought him into her bedroom to recover, and she could easily guess why it had happened.

He had been bitten by his Spider.

Much earlier than he should have, but this universe was already whacky as outside of her sisters, as heroes she remembered from her world, were Heroines in this one, and there were other Spiders outside of her sisters.

Ana, Julia, and Gwen who had all gotten Spider-Powers through various means during her tenure as Spider-Woman in this one.

She could feel it through her Spider-sense, his own budding one.

She could feel his body changing as she ran a palm across his skin.

She didn't know how long it would take, but she would stay with her Father through the entire process, just like her Peter had with her, when she had come of age.

May knew that this Peter wasn't her dad, but she still found it hard to not refer to him as such in her head.

Peter Parker was her Father, no matter what universe or age, for Mayday Parker loved her Daddy.

"Don't worry, Daddy, this time you won't have to go through this alone; we are here with you forever and ever," May said as she went to hold his hands even as pained moans escaped from this throat.

It didn't take long for May Parker to fall asleep next to her 'Nephew' still sitting in chair as she did so.

And so got the full brunt of one of Peter's new 'powers.'

A few hours later, May woke up and let out a husky moan as her entire body felt tingly, no hot in a way it had not in many, many years.

A warmth was pooling in her crotch, and then she took in a breath through her nose, and a nostalgic smell entered through her nostrils, and the feeling increased as she felt her pussy get wet with arousal, and she quickly located the source of that scent.

The source being Peter, who was still sleeping, but didn't seem to be suffering anymore, going by his steady breathing now and lack of burning forehead and…

"Oh my," Mayday Paker said as her eyes landed on the lower section of Peter's body, where she could see quite the impressive bulge in his underwear where the delightful scent was coming from. And forbidden thoughts and memories came to her. "Is it just like Daddy's?" She asked herself.

As a long-buried memory of her and her sisters watching their Father making their Mother roar in pleasure as he made lover to her. Their hands between their legs as they imagined themselves in their Mother's place.

And now she fully recognized the scent she had been smelling, the nostalgic smell of her Daddy's musky cocks.

And she meant cocks.

As then she pulled down the hem of Peter's underwear, two massive shafts of cock meat rose up into full erectness.

For why shouldn't he have two cocks? He was a spider, and spiders had two shafts that functioned as penises they used to impregnate their mates.

So a male-spider hybrid would obviously have grown an extra shaft… it only made logical sense, Mayday Parker thought as she was completed, by lust, Pheremones, and dark desires opened her mouth and started swallowing one of the foot-long shafts, while the other was jerked off by her hand.

And it did not take her long for May to get the fat load of cum she had been hungering for since she had been a teenager.

She wanted to move on to the next part, waking Peter up via her holes, taking his virginities, but she would save it for later, as she wanted to gift her body in full to her Daddy when he was fully awake.

For May had just crossed a line that could never be uncrossed, so she might as well go all the way, for Peter Parker deserved everything in the whole world.

May cleaned up the cum that was still staining her face, and also was coating around his crotch as his dicks softened, and since she figured he would awake soon so she should go and make a proper breakfast, as she thought he was going to need it.

May left the bedroom and went up to Penni and Peter's shared bedroom, where her daughter had already woken up and was getting dressed. "Morning dear, Peter's fever is gone."

Her daughter smiled. "That is great."

"So I think he is going to wake up soon, so could you go and sit by his side until he does?" May asked her daughter, as she knew what would happen if she sent her daughter into a bedroom filled with Peter's musk and his cocks but a flip of a quilt away.

She actually hoped something would happen.

As she had raised Penni, her beloved daughter, his granddaughter, to be his perfect little fuck hole for when the time came.
