The door is opened

Suddenly, behind of you the door opens and a familiar voice asks rhetorically: -May I say something about it?-.

Your sister freezes agape and you turn around in surprise. The person who has just entered is... is you! Your real body, that is! He has his, yours, urgh, its arms crossed and a frown on its face, and he's looking at you! D-Damn, it's so unreal, he's identical to you! Well, he is you and you're not anymore, but still you've never imagined something like this!

-You will forgive me if I've overheard, sister dearest.- He adds referring to Kim; then, looking at you: -And brother.-.

-Who... who are you?-.

He has really your voice, like, your real voice! It's incredible and, and a bit scary too.

-Come on guys, what do you think?- He snorts: -Uh, so this is how I'm seen from the outside.-.

-Tina??- Kim exclaims within Tina's body. "Tom" raises an eyebrow: -Took you enough.-.

-What? Why are you in my body?- You scream, but "he" beckons you to lower your voice.

-You two didn't leave me any choice, duh. Hell, it's strange for me too you know? This...- He flexes your biceps: -...this stuff. I feel so... bulky.-.

-Do you know what's happened to us?- Kim asks, and Tina looks at her (that is, at her own body) with a weirded expression before replying: -No idea. As you were saying, I was just having fun when I've been ejected from my body. Before I could set up my mind and crawl back, I saw you enter and I hid. Then you possessed my body and when "Kim" came too, I decided to get Tom to have a tranquil talk between us. What?-.

Both you and Kim are incredulous.

-It's just... you seem so calm about it.-.

-I mean.- Kim adds: -You were, erm, when I, you know.-.

He rolls his eyes, playing cool again: -I only thought that freaking out wouldn't have solved the situation, that's it. Plus, sis, it's not that I've never heard you doing those things too...-.

Kim turns pink and panics: -S-Shut up! He is also here with us, you know?!-.

-Right. So I would appreciate it if you wore something on my body.-.

She now becomes pale and jerks, remembering she's still naked and that, despite the appearances, you are still a male. You, from your hand, drop your womanly head in embarrassment, feeling an intruder. However, your vision falls on the mound attached to your chest, and you hesitantly move your hands. Just some minutes ago, Kim said that she could recognize when her body was horny, and now that Tina has said those things...

"So it means... gulp... that she touches her body too... like I've done... oh J-Jesus...".

-What about you?- Your old voice makes you jump, and you quickly lower your arm. F-Fuck, what were you doing? With them assisting? W-Were you getting turned on by that?

-I, uh, what-what do you mean?-.

-Well, it must be strange for you too.- Your little sister, now brother, explains: -Passing from this to our sister, right?-.

-Don't tease him!- Kim scolds her, and you notice she has already finished dressing, with a plain pair of jeans and a t-shirt. Her struggling expression, between anger and mortification, is so out of place on your usually calm sister's face that you have to look away to hide your agitation. But yet, if she could recognize her own excitement...

-Yeah, it's a bit... w-weird...-.

-I see. Curious, in a sense you seem even more feminine than her.-.

-Oh God, I have two perved siblings!- The false Tina hisses, while you feel your face blush.

-Mh? No, you got me wrong, I took his body only to play on equal terms.-.

You're again a bit awed by her coldness on this topic, especially considering that it's your body she's talking about. Kim, instead, is just more pissed: -Five minutes a male and she already acts like the hotshot! Urgh, fine cowboy, it's a Mexican stalemate, now what?-.

You decide to intervene: -Hey, calm down! Let's take it easy, we are all on the same side, right? Besides, we just have to get out from each other bodies and go back into ours, am I wrong? Uh... w-why are you looking at me like this?-.

-Do I sound this pitiful usually?- Kim bitterly asks. You have to admit that, coming from "Tina", it hurts a bit.

-You're right big bro.- Tina replies, cheering you up a little: -But I'm not sure how to. You know what happened to me, what about you? How did it happen?-.

-Umpf! I was doing my business until this creep decided to hijack my beautiful body. I got out just because... well, as you did.-.

-I...- You mumble, feeling the judgment of both your sisters over your fragile, minute head: -I just felt strange, that's all.-.

-Mmm...- Tina mulls it over, giving to your body an aura of smartness you doubt you've ever had.

-Well, I don't feel any strange now. So I guess that we have to do the other thing.-.

The other thing... wait, is she suggesting...???

-Absolutely not! This perv won't lay a finger on my body anymore!-.

-Kim, I...-.

-Shut up!-.

-Kim, try to be reasonable. We either do this together, or we don't, and I don't think that there is another way.-.

-Well, maybe for you two pervs won't be a problem, but it's still my body, and I decide over it!-.

-Then I may say that you're in my body, so I can make you comply.-.

Kim takes an angry step towards her, who in contrast sticks your chest out.

-Girls, girls, please!- You stop them one hand each.

-Listen me, uhm, Tina, as you said we're in this together, we don't have to argue. Maybe, maybe Kim is right, we need to think over a bit more, uh, maybe after a good sleep we could...-.

-Hah! "Sleep", of course! Like I'm leaving you alone in my body!-.

-Kim, quit it. He's trying to be helpful, unlike you.-.

-What did you say??-.

-Girls!- You hold them twice by their chests: -Let's not wake up mom again. Ok, no sleep. Then let's, you know, let's try to get out now, I don't know let's focus or something like that.-. They both agree to this attempt, but it turns out to be vain. After five minutes of eyes closed and grunting, your elder sister throws in the towel.

-Nothing, I can't do this.-.

-Me neither. Tina?-.

-Ehm... no...- Her tone is odd, like she's ashamed for something.

-But now I feel strange down there, like... pulsing.- You look at "down there" and you gasp as you recognize the bulge inside your pants.

"G-Good Lord! Tina is having a hard-on in my, in my body!!!" This is wrong on so many levels you don't even know where to start, you just stay like that, astonished, while she grinds your face in struggling expressions.

-We are hopeless.- Kim massages her forehead in defeat: -I don't like the idea of you seeing me naked again, but I like less the fact that you may be stuck in me until tomorrow. I can't believe I'm saying this but: fine, let's do it.-.

-W-Wut? You're saying that...- She snorts, but she's giving you her permission. Her permission! To do that again! In her wonderful, hot body you're in! It's, it's incredible!

-Goddamn, stop smiling, you make me look like an idiot.-.

You watch Tina, searching for some objection, but she just nods at the idea. It's settled then: you're going to masturbate again in Kim's body... and Tina in yours, touching your prick! Although the last knowledge makes you panic, you're also feeling hotter and hotter, like you wouldn't just like being the one receiving the handjob, but also... also giving it. With dainty, manicured hands. And so...
