So you know the meme 'You are four years old, and you suddenly gain awareness and consciousness'?

Yeah, that was what happened to me as I suddenly found myself no longer in my own body but in the body of a four-year-old boy.

Specifically, the four-year-old body of one Kevin Levin, the main rival and also archnemesis of one Ben Tennyson, and also half Alien going by which version of the canon was currently happening.

As I had no idea at the moment as the woman that was my Mother looked nothing like the Mother Canon Kevin had in Alien Force.

As my Mother, Ranko Levin, was clearly Asian with a very voluptuous and lewd body that was certainly not constrained by the rules of PG-13.

As I woke up to sitting on her lap with a nipple in my mouth as I drank from her lactating boob.

"Hmm, I really should not keep doing this, but it feels so good when you do this; Mommy loves you so much," Ranko cooed at me as I kept drinking that sweet nectar; I could tell this was gonna be constant in my future.

Well at least I wasn't dealing OG series Mom.

"I love you too, Mommy," I said after pulling off the fat nipple that I had been sucking on and giving Ranko the biggest smile I could.

"Ah…" Ranko delighted in happiness as she pushed my body into the cleavage of those massive breasts of hers. "Mommy loves you too."

It had been sudden, and I would miss my old life and family, but this? I would happily take this over what bad things that could have potentially happened to me.

And so my life as Kevin Levin began, and the first thing on the docket?

Befriend the shit out of Ben Tennyson!

So, finding and befriending Ben was an easier thing thought than done as I was a four-year-old kid. Bellwood looked to be a pretty big city, so there was really nothing I could do to speed up that process. Still, after two years of being an adorable toddler, it was time for me to enter Kindergarten; due to when I had been born, so I was six while most others in my class were five.

And it was there that fate had decided to throw me a bone, and I was paired up with a brown-haired boy with green eyes that shone like emeralds.

"I am Kevin," I said as I looked at the adorable Kindergarten version of Ben, which didn't say much; everyone in this reality had been hit the comic book glow-up, even I had been.

"My name is Benjamine, but everyone calls me Ben," he responded.

"Wanna be friends?"

"Sure, do you like robots?"

"Who doesn't?"

And that was how I had made my fastest friend in either of my lives, as Ben just proved to be an easy-to-get-along-with person even as a five-year-old.

Though I didn't know if because I had been obscenely dense or because the universe just conspired against me(probably both, along with the comic book pretty that just made every young kid androgynous looking), but it was after three years of friendship with Ben that I learned that…

He was not, in fact, a he but rather a she.

As there was no dying, Ben was a girl due to a beach trip, and she had been wearing a bikini that had highlighted her budding female parts.

It was a sight I had not expected to see at all, so of course, the first words out of my mouth were. "You are a girl?" I asked as Ben got out of the changing room, which immediately made both Ranko and Ben's parents laugh as Ben just stared at me.

"What do you mean by that, Kevin?" She asked as she blushed. "Stupid Kevin." And with that, she sprinted off and I was just left confused.

"Wait! Ben?" I shouted as I followed after my friend.

"Kevin?" I heard Ben ask as we laid about in my room; almost two years had passed since the fate full day I had learned my bro was a gal instead.

"Yeah…" I responded as laid on my bed reading a tabloid about aliens among the people of Earth, which just made me laugh as I was half-alien and Ben was… one-forth? Well, technically, she was a full Anodite if she had the spark like Gwen(I still hadn't actually met her, but I had heard about her, as her part of the family didn't live in Bellwood, but according to Ben, she had said her cousin was going to move here soon.) had, but something told me that wasn't the case.

"Do you think I am weird?" And I sat up to look at the short-haired girl who was my best friend who was currently wearing that baggy clothing she had decided was her new style, but even so, I had to admit her hips and butt was filling out those cargo pants of hers pretty well.

"Why are you asking that?"

"Hmm, the other girls…"

"What are they saying now?" I asked, and while I shouldn't hold nine-year-old girls to a very high standard of social awareness, I was gonna, and I was gonna call them all cunts. "Are they bullying you about you liking 'boy'-" My voice was dripping with sarcasm. "-things again?"

"They haven't in a while," She answered. "But they said it was weird for my things to be so big already."

Well, that was a turn I didn't expect the conversation to turn, and while I knew the alien DNA was making us mature way faster sexually, as I had heard the sound of Ben waking up to her first period last year. I didn't think it was going that fast, as I still hadn't gotten an actual proper erection yet.

"They are probably just jealous," I responded.

"So you don't think my breasts are weird?"

"…No, Ben, I don't think your breasts are weird; I haven't even seen them in a while, so how should I actually know," I responded, which sounded extremely weird after the fact, but I hadn't known what else to say.

"What do you think now?" Ben said as she lifted her baggy t-shirt and my eyes did go a little out of my skull as I looked at the large globes of fat that sat on Ben's body, cementing her status as an Oppai Loli if one were to be a fility weeb like myself. "You still don't think these things are weird."

And with that, I felt a thing slot itself in place in my head, and I, for the first time in this body, felt a familiar pressure in my pants.

"They are lovely."
