Saturday....

It was a Saturday and Flukey, Makoto, Sekai, and Kotonoha were at the water park. 

Flukey and Makoto were already finished changing and waited patiently for their girlfriends to finish changing into their swimming wear too.

Flukey: (Man the girls have been changing for a while now. I hope they're alright)

With Kotonoha and Sekai....

In the changing closets, Sekai was done changing and left her closet where Kotonoha was standing at her door, waiting for her. 

Because she didn't notice Kotonoha in time, she jumped. 

Sekai: Hah! Oh....it's just you Kotonoha. Boy, you scared me. 

Kotonoha just stared at Sekai and it was making her a little uncomfortable. 

Sekai: Uh....Kotonoha....why are you staring at me like tha--.

Then Kotonoha cut her off.

Kotonoha: I know you slept with Makoto. 

Kotonoha's voice was soft but serious and the way she looked at Sekai told her that she wasn't lying. 

Sekai's eyes widened a bit as she gasped. 

S-Sekai: H-How did you find out? 

Kotonoha: I saw you and him on the roof at school. And to answer your next question, Flukey doesn't know and I'd much prefer to keep it that way. He's a really good friend to me and hurting him is the last thing I want. If you promise to stop what you're doing with Makoto and keep it, I won't tell Flukey. That's all. Now shall we go? 

She then had a "warm" smile on her as Sekai just looked at her with a fear on her face. 

Kotonoha knew her secret and was threatening to tell Flukey if she kept things up with Makoto. 

As much as she loved Makoto, she also didn't want to hurt Flukey. She never wanted to from the start but now that the deeds been done and with Kotonoha confessing to knowing her secret, Sekai's heart was racing with both guilt and desire. 

Sekai and Kotonoha left the changing area and joined up with Makoto and Flukey who could see them in their swimsuits in all their glory.

Flukey: Looking good babe. 

Makoto: Uh yeah. You look nice Kotonoha. 

Sekai blushed from Flukey's comment and Kotonoha looked pleased with Makoto's comment. 

Soon the quartet started to enjoy themselves at the waterpark. 

Flukey and Sekai had a small splash fight and Kotonoha and Makoto had some ice cream together. 

During that time, Makoto made up some excuse that he needed to speak with Sekai about something private but in reality he just wanted to have sex with her again. 

Sekai agreed to meet with Makoto in private but not for the reason he was expecting. 

Now alone, Makoto started to put the moves on Sekai but she pushed him back. 

Makoto: Hey what's wrong? 

Sekai: I'm....I'm sorry Makoto. But we can't do this. 

Makoto: What? Why not? 

Sekai: Because Kotonoha knows about us. She saw us while we were having sex and threatened to tell Flukey if I continued to cheat on him with you. And even then, Flukey's an outstanding boyfriend and doesn't deserve to get cheated on.

Makoto: So then break up with him. If you're feeling so guilty about what you're doing then just leave him. You said it yourself remember, you love me more than you love Flukey. So why not follow your heart and be with me?

Sekai: And what about Kotonoha? She's innocent too. 

Makoto: I'll tell her that I don't want to be with her anymore. And we can finally be together like we should've been from the beginning. To be honest, I don't really love Kotonoha. I love you Sekai. And only you. 

Makoto gave Sekai a hug and his words was enough to sway Sekai to listen to his suggestion. 

Sekai: A-Alright I'll do it. What would be a good time though? 

Makoto: Let's both do it on Monday. 

Sekai: *Nods* Okay then. 

After they explained their plan further, they then had sex while leaving their significant others to themselves.

With Flukey and Kotonoha....

With Flukey and Kotonoha they were sitting at a table and and talking with each other but noticed that Makoto and Sekai had been gone a while. 

Flukey: Man Sekai's been talking with Makoto for a while now. What could they possibly be talking about?

Kotonoha just sat there, mildly angry and disappointed at Sekai for not heeding her warning. She silently sighed to herself before turning to look at Flukey. 

Kotonoha: Flukey, there's something I have to tell you.

Flukey over to her. 

Flukey: Hm? What's up? 

Before Kotonoha could continue, Sekai and Makoto came back. 

Flukey: There you two are. Seriously what were you two talking about that took up so much time? 

The tone in Flukey's voice was one of slight irritation but Makoto had an alibi. 

Makoto: I was just talking with Sekai about my family problems.

Flukey: And you didn't think to consult with your own girlfriend about that?

Makoto: I mean yeah but I thought I'd led Sekai know too. I was gonna let you know as well I promise. 

Kotonoha had to give it to Makoto since he had informed her of his family troubles as well. 

Flukey then looked over at Sekai who looked back.

After a few seconds, he just sighed. 

Flukey: Fine I'll take your word for it. We've been here long enough. Let's go home. 

Sekai: Okay. 

After changing back into their outdoor clothes, Flukey and Sekai went one way and Makoto and Kotonoha went another way together. 

Before parting, Flukey remembered that Kotonoha had something to tell him and when he asked her about it, she told him it was nothing. 

During the walk, Sekai was in mentally in turmoil. 

Kotonoha knew her secret and threatened to tell Flukey if she continued to see Makoto, but Makoto convinced her to to break up with Flukey and be with him. 

Even though hurting Flukey was something she never wanted, just like Makoto told her to she was going to follow her heart. 

No matter what.
