A threesome

You are relaxing in your room, when your sister suddenly comes in.

Hey, what is it? You want some sex again?

Not really. Or maybe that, too?
Anyway, I have a question.
So you still have sex with Lydia, right?

Yeah, why?

Uhm...
I'm also having sex with her again, you know?

Oh, nice. Yeah I expected this.
So how is it?

I like it. Lesbian sex can be great, too

Nice, that sounds great.
I wish...

Are you envious?

No! Don't worry, I'm not. Really.
Not at her nor at you.
I just wish, I could have seen it.
This would surely have been nice.

But that's not what I wanted to tell you.
I was just talking to her and then we had an idea.

An idea? Wait, is she at our place?

Suddenly the door opens and Lydia comes in.
She immediately hugs both of you and even kisses you.

So it's really true? You have sibling sex?

Were you listening?

Lydia nods, seeming a little embarrassed.

Yes, we have once in a while.

I already told her. So she knows.
We thought, we might have sex with you at the same time.
And then I'd have sex with her while you're with us.
What do you think?

Oh, a threesome?

Sorry, I guess, that's a weird idea...

No, it sounds fine. And you like it, too, Lydia?

Yeah, sounds interesting.

So then, let's get naked.

Oh, right now?

Is there a reason not to? Our parents aren't at home.

No, it's fine. I just wasn't prepared. I didn't even shower in advance. But I probably didn't need to anyway.

I never shower just to have sex with my brother.
I rather shower after we finished.
I think he even likes it when I just was doing sports.

That's a little embarrassing.
But you noticed she was still doing a lot of sports, even after she got her body back.
And you kind of like her sweaty smell.

Maybe that's a sign, that you match.
So maybe it doesn't matter that it's incest.

Okay, I hope you like it too if I smell.

Lydia giggles in embarrassment.
And you are even more embarrassed now.
She didn't have to say this.

So you get up and get undressed.
You've been naked with both of them, so it isn't a big deal.
You feel pretty familiar with them already.

And they also just start to undress.
They must feel similar to you.
They also had sex with each other already.

When all of you are naked, you go into the bed and the two girls lie down next to you, snuggling up to you.

They gently start stroking your chest, and one of them grabs your dick, you don't really care who of them.

You also put your arms around them and stroke their backs and their butts and soon you even put your hands between their legs, stroking their dirty pussies.

Having two girls you like next to you is really amazing.

You turn your head to the left and kiss your sister, then you turn it to the right and kiss Lydia.
And next both of them kiss you on the cheeks.

So, I'll get on top of him first, okay?

No, let me show you. I already know how he feels.
This body was mine for a while after all.

Your sister climbs on top of you and tries to sit down on your hard dick.
Lydia holds it up to help her.

Then she gently starts moving up and down.

So is it really true?
Did you really swap bodies?

Yeah.
So you already know everything?
That it was actually me during our frist time?

Your sister continues moving the body that has been yours for all the time, making your dick feel great.

Yeah, during our second first time she told me that it's her first time.

Yeah, but I'm glad you taught her about lesbian sex.
She really was amazing.

When is it finally my turn?

Yeah, if you don't switch soon, I'll cum into my sister.

Then just start!

Your sister gets up and Lydia takes her place.
She just fucks you like she usually does.

See? I already practiced.

Lydia moves her ass very dynamic. It feels better this way.
But somehow she also doesn't make you cum.
You're already on the edge.

Yeah, you are a natural talent!

No, it's all practice. I already practiced a lot in the last days.

But she was great from the beginning.

Yeah, I really regret that we didn't go further on our first date when I still had the body of my brother.
I'm sure she would have been better than you at least.

You giggle.

Don't be so mean.
I was great as a girl. I also had a lot of practice!

Your sister is surprised and Lydia stops moving.

Nevermind. You probably don't want to know.

Your sister looks at you with a serious expression, then she sits down on your face.

Yeah, I don't want to know. But that's still worth a punishment.

You lick her ass and you also notice Lydia bending down, probably licking her pussy.
Your sister has to moan loud.
You're really glad your parents aren't here. Hopefully your neighbors don't notice.
She's probably having an orgasm already.

Your dick, still being enclosed by Lydia, is getting very warm.
She also moves slightly and soon you have to cum into her.

Your consciousness fades away for some seconds, and when your senses come back, both girls are lying on the right side of you, cuddling.

Oh, you were great Lydia.

Yeah, you made me cum really hard.

Did I also make you cum.

No, I didn't cum. But don't worry.
This way I will come back much sooner because I'm horny.
And then you can make me cum all the more.

Yeah, great idea. Let's repeat this soon.
We might do this regularly.

Maybe I should try it, too, one day.
I also want to swap bodies.

So you want to be a boy?
You want to swap bodies with me?

No, rather with your sister.

Why that?

Because I love her cute body so much.
Then I could be with her all day.
And besides I'd stay with you.

Yeah...
So you only love me because of my body...
But it's okay. I also have some fun ideas with such a sexy body like yours.

What is it?

It's a secret.

I guess I can't blame you for that.
At least I'm not the only pervert here.
Just let's try to stay honest from now on.
I don't want to lose both of you to other guys.

I'm sure one of us will stay with you forever.

Probably Lydia. At least her body. But we won't tell you who of us it will be.

They look at each other and giggle.

I guess I'm fine with that.

You also have to giggle.
Even if the person controlling her body will be somebody else completely, you will still have a sexy girlfriend at least.
