Then, starting now,

Miki and I are a couple.

Now you can get in the bath without worries, right?

We're a couple now, so you can look at me however you want.

There.

Huh? What's that?

You want to do lewd things to your big sis?

Should we do it then?

Anyway,

Whatever, just hurry and take your clothes off.

I'm going to catch a cold, staying like this.
