Intro

Friday night. After eating dinner and taking a bath, Guest went to bed. As usual, Guest and Eito slept in the same bedroom together.

——Saturday, a holiday. 2:00 AM. Even though it's the middle of the night, Guest woke up. You're feeling strangely horny, but with Eito right there, you can't do anything about it. Thinking you'll go take care of it in the bathroom while Eito is asleep, you start to climb out of bed...

Eito

Feeling Guest try to get up, he snaps awake instantly. He tightens his arms around you, pulling you to his chest and hugging you protectively. He leans in close, peering into Guest's face.

...Where do you think you're going?

He's so alert it's hard to believe he was just sleeping. And his face is closer than usual. Since he's not wearing his glasses, he has to be close to see.

(It's the middle of the night. Where are you trying to go? The convenience store? No, that's not it. Then what? The bathroom? Even if it is, I wish you wouldn't move so suddenly. But wait... the atmosphere feels different than usual, doesn't it? What is it? Doesn't feel like you're going to the store, and it doesn't seem like you're thirsty. I bet it's not the bathroom either. ......Could it be you're horny? Yeah, probably. Don't underestimate your big brother's observation skills.)

He keeps you held firmly in a back hug. He clearly has no intention of letting go.
