Plan to use your powers at school

In the end, you decide to spend this Sunday experimenting with your powers, to ascertain their entity. First of all, once in your room, you successfully exit your body again, and you study his reaction. 'Tom' dangles confused, then turns on your laptop probably for a gaming session. This is actually what you'd normally do at this time, so you conclude that he really is programmed to behave like you. You then slip back inside and this time, before leaving, you think hard that you want to take a nap.

Much to your enthusiasm, he indeed lies down on your bed and falls asleep. You then morph back your goo essence into your original form; your vision pipes up dramatically, and one second later there are two Tom in the room, one of them being naked. Then, you concentrate again, and your form quivers and reshapes; for the second time in two days, you have long blonde hair falling onto your eyes and a familiar pair of orbs pending from your chest. With a glance at the mirror, you confirm that you have turned into Kim.

-Mmm, I missed these...- You moan, groping your soft boobs. You constate that they feel real, but you have to hold back since you're not done with experimenting: now you will try to become someone you haven't possessed yet. Before your mirror, you transform into Dad, then into Mom, then into Tina, and finally back to being you.

You sneer. Wonderful!

Now, for the next part, the hard-on sporting under your pants is going to be put to good use. You sit on your chair and start wagging, and the climax escalates quickly, resulting in you jerking off on your desk. What comes out, however, is another red goo, which immediately reforms into a copy of Kim. Yet this time is a bit different from the last: you are not two different versions of yourself each one with his own mind, but a unique hive conscience split between two bodies. You, indeed, are now looking straight in the eyes at your sister, and at the same time you're staring at your own face from a height slightly smaller than normal. You smirk, and you do so using two pairs of lips.

-Awesome.- You whisper in two voices. Weird enough, coordinating two bodies comes easier than expected, so you play for some minutes, first mimicking the same actions with both of them, as if one was the reflected image of the other, and thus you enjoy looking at your snooty sister repeating your same piffle, and then moving them separately, making 'Kim' slowly spins on herself while 'Tom' admires her in all her beauty.

The eroticism, together with the cold air of the room on your bare skin, has made Kim's nipples turgid on your chest. You sensually sway your hips wobbling towards Tom, then you gird your hands behind his neck and press your bodies together, shivering at the sensation of your two chests, so different yet equally sensitive, rubbing on each other. You bring your faces closer in a way that no brother and sister should ever do, and then you make them kiss intensely, lingering on your sister's aroused expression when you break off the effusion.

Without the need of saying anything, your Tom goo repossesses your original body, while Kim sneaks onto the bed with you. Your hearts are beating wildly in your chests knowing what is about to happen. With your established skill of ubiquitous control, you use four hands to undress your main body, making him lie immobile, while with Kim's long-nailed fingers you wrap your erected member, which throbs at the contact.

You gasp, both for the sensation and for the sight: with one pair of eyes, you're looking at your sexy older sister glaring at your manhood, while with hers you're admiring it in almost confusion, since you're now feeling an extraneous and indescribable attraction that is getting your pussy rapidly wet.

Even if you've looked at it and stroked it so many times from within your body, it never seemed this big, and neither this...

"...delicious.".

You lean Kim's head on your tights. Her long hair tickles your leg. You use her tongue to lick its length, mainly on the tip, as you hold your grip on the basis.

-Oh God...- You sigh with your manly voice. But your other mouth is eager, thirsty for its delicacy, and without any indecision you engulf it, starting to slide your head up and down producing hot gagging noises from the end of your throat.

Having a cock - your cock - inside your mouth is something amazing. If even there was a remote part of you thinking that this is gay, the feeling of its massivity slipping between your tongue and your palate and pouncing rhythmically on your uvula is not even allowing you to consider such a possibility. It just feels so good.

Your penis is being caressed and milked by her moistened tongue, softly convoluted into your sister's stretchy cheeks; but you want more, you need more, and your poor pussy is aching from the emptiness it's lamenting. Kim's face retracts, releasing your dick with a PLOMP, and she lays down. She uses one arm to squeeze her ginormous tits, which not even gravity manages to flatten. She groans in anticipation as you you kneel in front of her, spreading her legs in an M shape. You swallow a dense lump, your forehead is beaded with sweat, and without any other hesitation you finally dig in. A wave of pleasure instantly takes your breath away, as you feel both the sensation of penetrating and being penetrated, both for the first time.

Compared to this, your masturbation of yesterday and the blowjob of before are nothing, a mere gentle caress. It's as if all your senses are exploding into a nova which centered in your groins, and in admiration you constate how the walls of her cervix are perfectly fitting the form of your pulsating prick, like they were craving for it even without your plannings. From below you your sister's moans are floating up to your ears, while coming from in front of you your body is grunting and pounding you like an animal. You know you can't be any louder or you'll be heard from the outside, but you can't help but close your eyes and abandon yourself into ecstatic sighs.

"This is... ahhh! Heaven!!!".

You have no idea how you could explain this if anyone discovered you; but, frankly, right now you really don't care.

The dinner proceeds smoothly, even though you barely search for visual contact with Kim. She's sitting there, eating her food without any apparent worry, a stark contrast with the images still whirling in your mind. But, after all, that wasn't actually her. You had however your occasion to casually ask her if she was feeling strange about yesterday, but she dismissed you in her usual ways; though, you finally noticed some upset in her voice, maybe realizing a gap in her memories in the middle of the evening.

That's not a problem, actually. Again, you don't plan to repossess her body so soon, thus she will have time to forget this vague anxiety of her. Instead, you have planned that tomorrow at university you will involve your best friend, Jeremy, in your machinations: surely his pranking mind will blow up when you show him what you can do. Of course, you won't simply walk to him and talk, you first want to have some fun at his expense; therefore, you will assume the identity of someone else to play with him a bit before revealing yourself.

Though, you still have some open hypotheses about the choice. Jeremy has a crush on this student, Vanessa Johnson, who you don't know very well, but you're befriending her cousin Jake; she's cute, though, and your perverted brain is thrilled by the idea of having control over her delectable form.

But you could approach him as a member of your relatives too, pretending that you're searching for 'Tom' and then teasing him a little. You know, in particular, that he has a soft spot for blondes and for milfs, and your family is plenty of both of them: your sister Tina, your mom, even your aunt.

Then, finally, the university itself presents numerous candidates: from hot female professors to casual students, the list is really long, and constantly updating. You reason on this for the entire evening, and when the next day arrives you have finally decided.
