The plan

Today you really want to get your normal body back.
Life with your new body is getting annoying.
School is boring, you just repeat stuff you already learned years ago.
You don't like most of your female friends.
Even your best buddy doesn't stop molesting you when you visit him, so you don't even want to spend time with him anymore.

When thinking about that, you really have to tell him as soon as you turn back, so he won't accidentally molest your real sister.

The three weeks your sister wanted to stay in your body must have passed already, so you visit your sister in your room.
She's just relaxing there.
Her body is still very muscular. Even more so than before.

Hey, you look great. But it's time. You promised!

Oh, already? I'm so close.
Could you still do one thing for me?

What is it?

I'd like to introduce you to him.
I want you to become his girlfriend before we swap back.
Once that's done, you can get your body back immediately.

Really? Can't you do that yourself?

You know best how to act around boys.
Please!

Okay, but in exchange I want to introduce you to some girl as well.

Some girl? Who is it? One of my friends?
Maybe Nelli? Or Kana?

No, it's Lydia.

Lydia...? How did you end up with her?

You don't want to know.

I guess, you're right...
She's been pretty kinky around girls.
So I'm not surprised you like her.

Yeah...

So if I make friends with her as you, you will get closer to him as me, right?

Yeah, that's the plan.

Deal!

We shake hands.

We'll meet here in a few days. Just be at home after school.

Okay, recently I'm at home a lot anyway.
And I'll bring Lydia with me tomorrow, okay?

Tomorrow already!?! Okay...

Or do you prefer another date?

Let's say in three days. And I try to bring him as well, okay?

So a partner swap? I like that.

Your sister nods and you leave her alone.

When you meet Lydia the next time, you ask her if she has time that day, and she agrees.

But why will we meet at your place?
You weren't talking about your brother, were you?

Uhm... would that be a problem?

Lydia seems excited.

I'm just getting nervous. He's pretty nice, isn't he?

He's okay I guess.
Sometimes he can be pretty annoying. But I'm only his sister, so...
But I'm sure he's into you. So he'll definitely be nice to you.
At least if you consider me to be nice. I've seen him act just like me around good friends.

I didn't expect you to have so much in common.
Even if you are family, he's a boy and you're a girl.

Yeah, it's pretty funny, isn't it?

So do you think, he would also try to cuddle naked on our first night together?

I don't think so. Maybe you shouldn't be too outgoing like you were at the party.
I'm also not that outgoing when it comes to the other gender.
I'm sure he will let you know when he's ready.

Okay, I'll try to hold myself back.
I don't want to make a bad first impression.

Sounds like you are okay with him.

Yeah, I'm really glad it's him. Especially when you say he's similar to you.

Just don't expect him to be too similar.
He might need to get used to you.

Yeah, you also were much different for years.
I still wonder why it took us so long to become friends.

You smile at her.
Yeah, this way she won't force your sister to have sex with her, and you would still be able to have sex with her when it's time.

On that day, three days after the planned date, you bring Lydia with you when coming home after school.
You already talked with your sister about your exact plans, so everybody has the same story and everything should work out well.

Hey, Phillip, I'm home! Could you come, please?

Hey, Paula. What is it?

Your sister leaves her room in your body.

I brought a friend today.

Oh, I didn't know you were friends with Lydia.
I thought, you didn't like her.

Yeah, but I found out about something so I wanted to help you.

Uhm... how did you know?

Are you serious? You didn't only befriend me to help your brother, did you?

Don't worry. It's part of the plan.

Hey, nice to meet you! So you're Phillip?

Yeah, nice to meet you Lydia.

So you've noticed me before?

Yeah, kind of...
I hope, that's not too weird?
I'm a few years older after all.

No, I always thought, you look interesting.

Not sure if she really has been into you all the time.
You definitely weren't.
But it would still be a nice story if both of you independantly showed interest in each other.

Theoretically now they don't even need to meet anymore.
You would prefer if they don't meet.
It could just go wrong. Or even worse, it could work out and your sister starts to like her for real.

In any case, them spending time alone would feel like cheating already.
You don't mind what she's doing with other girls, but with other boys...?
It doesn't make a difference that the other boy is basically you in this case.

So... would you like to meet soon?

Yeah, that would be great!
Why not come to my place right now?
My parents won't come home until late in the evening today.

Hey, no need to be so hasty! You'll meet soon enough!

Sorry, but I have a friend of mine here today.
Maybe some other time.

Who is it?

She really seems excited.

Who cares.

Suddenly the guy leaves the room.
He doesn't even wear a shirt.

Oh, who's that?

Oh no, she seems to like his body.
She isn't allowed to get into a relationship with this guy.
This would break your plan and the plan of your sister.

I grab her at her clothes and pull her back to me.

Don't do it, Lydia. A muscular guy like him surely won't be interested in you.

You really think so? I think it's still worth the try.

But my brother already likes you. He is basically safe.
But when you get closer to his friend, he might feel hurt.

That's my choice. And I think it's worth it.

And if my brother is your boyfriend, we will be able to spend even more time together.

Don't worry. I'll always find enough time for us to spend together.

Okay, let me be honest with you. I'm already into him.
I'm not sure what I would do if my best friend was with my potential lover.

Oh, if that's the case! I get it!
Bros before... whatever. But then you have to tell him now, okay?

What have you whispering? What should she tell me?

Uhm...

I really like your muscles! I'd like to...
Can we meet in private!

Oh, sure. I didn't want to stay much longer anyway.
Would you like to accompany me home?
That's okay, Phillip, isn't it?

Sure, you're my buddy after all. My training partner.
I'm sure I can trust you with her.

Don't worry. I wouldn't do anything weird with the sister of my friend.

Okay... that sounds... great!

She sounds pretty insecure.

In that case, you could just come with me to my place, Phillip, right?

Oh, I guess, I really could...

It probably will work out, but it's definitely not what you expected.
But you probably don't get out of this now.
You look at your sister. She also seems kind of desperate.

Hopefully she won't have sex with Lydia at least.
But it already looks like...

So, let's go! I'll show you my place.

You leave your place with the guy.
Lydia just smirks at you and even winks.
