Possess Hinatsu's voluptuous body.

"Very well, Hina" I address the gorgeous raven-haired girl whose plump breast is still resting over my(Melina's) open hand. "I've decided that I'll be taking your body for ride." I say while releasing her udder and taking a step back. My thin shoulder was getting tired from the weight. "So get down to your knees if you please."

For a moment, Hinatsu stares at me like a confused idiot. But once her startled brain has finished processing the meaning of my words, she instantly jolts forward, falling over her knees so quick that her heavy breasts can't even keep up with the main body's movement, opening to both sides towards the armpits and then smashing together in a resounding plop once the girl stops.
All of a sudden, her entire shy demeanor has completely vanished and her gloomy eyes are now fully open in bright anticipation. She looks eager and happy like a golden retriever about to go for a walk.

Every member of my family is special and unique in one way or another. But there is a feeling they all share, which is that every single one of them absolutely loves to have their bodies taken over by me.

I made sure of that when I tinkered with their brains.

I snort at my own thoughts. Only six weeks ago I was still a scrawny 19 year old orphan with no money or living relatives to care about. All I had was a small 1 bedroom apartment from Social Housing lent to me by the government along a little monthly allowance. And my belongings consisted on a few worn out spare clothes, a dozen books and magazines, an old laptop from the early 2000s and a prick that had become reddish and swollen from constantly wanking off out of pure boredom.

It was quite a miserable existence, and I barely got through highschool after repeating 2 entire years. At some point, I was so **** for money that I started accepting dubious job offers, like the one from that experimental lab that brought me to this point.

But now... I have a 'family' who loves me and is absolutely loyal, who 'kindly allows' me to possess and use their precious bodies as if they were mine. I've become rich and live in a beautiful mansion near the sea, with great food and excellent weather. My life used to be grim and grey, but now it has become a paradise full of posibilities.

I feel my cheeks blushing, my mouth wriggling up and down, trying to contain a perverted smile that has already conquered my eyes.

"Hold still now, my dear Hina... " I say in a low sensual voice while the millions of microscopic parts that compose my true body start the process of detaching themselves from Melina's cells.

Most of those parts come straight from the brain, and after a few seconds, when the detachment process is almost complete, I feel my conscience losing control over the girl's body.

"Open... your... mouth..." I tell Hinatsu while my vision is blurring out, and while the taller girl obeys my order, I use the last bits of control to wrap Melina's arms around Hina's neck and close my already drooling mouth over hers.

As soon as our lips join, there is a powerful chemical signal spreading through all the parts of my slimy body. And, in a process that lasts less than 5 seconds, those millions of pieces run through Melina's body, joining together in the stomach after filtering through its porous walls, making my shapeless body complete at last. But whole as I am, I don't lose even a millisecond before I jump upward towards the esophagus and, the next instant, I'm blurting out from the petite Melina's throat into Hinatsu's open mouth.

"Gahk, urk..." Hinatsu opens her eyes in alarm but she still allows my shapeless body to pass through without any resistance. And the instant I find myself into her slightly wider stomach, I take only a second of respite before I start the same process in reverse, spreading out along the stomach and the intestine, dividing myself and running through her bloodstream until I finally reach the brain.

The process of taking over a body always takes longer and is more violent than the process of getting out. And while Melina's now **** body falls peacefully over the thick carpet, Hinatsu's curvaceous figure falls in a rather unsightly way while twitching violently.

Some 10 seconds later, the twitching stops. And after another full minute, I slowly open my eyes, Hinatsu's eyes, and smile.

"Did the takeover go well, my dear?" Asks a mellow voice over me. I look at her. It's Caitlyn, of course. She is still naked and leaning forward while showing me her typical beatific smile. God, I really love that smile.

She offers me a hand and I eagerly accept it, slowly straightening myself up while the last bits of dizzyness fade away.
Hahhh... Is this feeling again...
I look down at the imposing mounds of pale flesh sprouting from my chest and feel slightly disoriented at the difference in length between the limbs I have now and the ones I had before. I feel heavier, and clumsier, and... cozy...
I embrace Hinatsu's body with her long arms, crushing her fatty breasts in a loving embrace while sitting cross-legged. This body is so warm, and feels so soft in all the right places. The only reason I've only possessed her a few times is because I feel obliged of constantly try new things and properly divide my attention between all my family members.

"fufu... It looke like you're enjoying youself quite a lot, my dear." Caitlyn points out in her soothing voice.

I look at the front, taking a few moments to admire the middle-aged woman's wide child-bearing hips. Her dark and abundant pubic hair looks moist and greasy after a night of constant sex. Before I know what I'm doing, I use Hinatsu's hand to caress Caitlyn's protruding vaginal lips and grab a chunk of the milky slime oozing from it.

"Hyah?!" She yells, caught totally off-guard.

I eagerly lick the goo directly from the palm of Hina's hand, take a moment to properly taste it, and smile with satisfaction.
Somehow, all this spunk still tastes good when it comes from Caitlyn's vagina. Melina still has a long way to go.

"Y-You...! You shouldn't d-do that, dear. It's... dirty."

I laugh at the idea that something coming out from Caitlyn's perfect body could ever be considered dirty. So I take a few extra moments to carefully lick my hand clean before I finally decide to stand up. And when I do, I can't help but step forward and put my(Hinatsu's) engorged nipples right next to those of the older woman.
By all standards, Caitlyn is exceptionally well-endowed. Her voluptuous body has always been turning heads ever since she was a teenager, no matter where she went or the clothes she wore. She is one of those rare cases who always had difficulties at making friends because the other women felt constantly threatened, especially the ones with husbands or boyfriends.

Hinatsu however... is on a league of her own. A genetic monster you couldn't find even if you took a hundred thousand women and inspected each one of them. She is taller than most men, her hips are round, wide and perfectly smooth, her belly is mostly flat, with just a tiny bit of protruding flesh over the hip; and her breasts are basically wonders of nature whose size and firmness almost make them seem fake. But they aren't. I can 100% guarantee that.

After inspecting the difference in size between our respective bossoms, I can't help but show up a smug smile while I proudly display my newly acquired boobs.

"I win again." I say in an annoyingly childish tone. Now that I'm in control of Hinatsu's body, her pretty voice doesn't stutter anymore.

Instead of being mad, Caitlyn just laughs at me.

"Hahhh... you rascal..." She says, shaking her head in a knowingly way. "By the way, you still haven't eaten anything since midnight. Come on then. We still need to wash ourselves first so I'll help you get ready before breakfast."

I nod with a smile. Caitlyn is the only person I regularly allow to give me commands.

"Yes, mom!" I exclaim, trotting happily behind her, and I notice a slight blush over her pristine cheeks. She really loves to hear me calling her mom.
My own mother died years ago, and she never acted like an actual mom to begin with, so this arrangement suits me well enough. After all, what kind of idiot wouldn't want to have Caitlyn as his mom?

But before I go through the door, I suddenly turn back.

"Dad! You come over too!" I call Steven, Caitlyn's husband. It occurs to me that I shouldn't have one without the other.

I nod to myself. Yep, the idea of accepting these two as my new mom and dad is definitely growing on me.

Once in the bathroom (it would be more adequate to call it a bathhouse), we carefully wash each other while chatting about little things, old news or the movie we watched yesterday afternoon in our private cinema. I enjoy washing my own(Hinatsu's) gorgeous body, extending the soap over her smooth skin and carefully rubbing the sponge through every crevice and curve. At some point, I have Caitlyn's soapy breasts wiggling all over my upper back while the woman cleans Hina's pitch black hair. And while she works on me, I work on Steven's wide back, rubbing it with two spongy mittens shaped like a frog's face.
The blonde middle-aged man looks completely relaxed, with his head leaning backwards and a blissfull expression all over his face.

"Are you enjoying this, dad?" I ask in a sweet voice.

"Y-Yes... I am... Master..." He answers with a satisfied sigh.

"Call me 'dear', like mom does."

"Yes... dear..."

"Heheh... That's more like it." I say in a whisper while pressing my humongous breasts over his back and kissing his nape, which produces an immediate grunt of pleasure from him.

I've always been an heterosexual guy. But once I started possessing different kinds of people and lived all those amazing experiences, I found out that I didn't care anymore. Not much, at least. There is a small part within me that still feels a little disgusted at the idea of pleasuring another dude. But somehow, that little rejection has never deterred me from doing what I wanted. All the contrary, it makes doing all these objectively 'wrong' and 'dirty' deeds way more exciting.

After a quick look, I notice that not all Steven's body is as relaxed as he is.

"Hmmm... It looks like your little friend didn't have enough last night." I purr in his ear.
