How to ruin a good porno game:

Yuki is playing a porno game on a laptop, as Haruhi and Mikuru enter the club room.

Mikuru: Oh jeez. How can you do that right in front of us?

Haruhi: Yeah. Even I draw the line at doing stuff like that in public.

Mikuru: ...

Haruhi: I mean... I would never play a game like that. It's disgusting!

Mikuru: (muttering) I'm not letting you see me naked again.

Haruhi: Hey! I know! Let's go do a photo shoot. Come on, Mikuru!

Haruhi drags Mikuru out of the club room, as Yuki obliviously continues playing.

Koizumi briefly enters the room.

Koizumi: Okay. I'll just pretend I didn't see that.

Koizumi leaves, and Kyon enters a minute later.

Kyon: Hey, Nagato. Where are the others?

Yuki: They decided to leave for now.

Kyon: So, it's just us?

Kyon goes and sits next to Yuki.

Yuki: Correct.

Kyon watches her play for a while, becoming more and more intrigued.

Kyon: Is that fun?

Yuki: You want to play?

Kyon: (thinks for a moment) That's... not really my thing.

Yuki: Do you object to homoerotic situations?

Kyon: No, I just can't get into it.

Yuki: Because you are male?

Kyon: Because I just can't see myself having fun with it.

Yuki: I don't understand.

Kyon: Well, think about it. The whole point of a good role-playing game is the gradual build-up. That's the beauty of it. You're supposed to feel like you're involved.

Yuki: True.

Kyon: That's the problem. I don't really feel comfortable with the thought of random sexual encounters. I'd feel like I was cheating on one to satisfy another.

Yuki: You don't like the thought of someone cheating on you?

Kyon: Hmm... (thinking again) Actually, I'm okay with that.

Yuki: You are?

Kyon: Yeah. I just can't stomach the idea of me cheating on someone.

Yuki: Why is that?

Kyon: (very casual) I guess because I'd be afraid that they would abandon me.

Yuki: ...

Kyon: What? Aren't you going to keep playing?

Yuki: No. It's not fun anymore.

Kyon: Whoa! Was that my fault? I'm sorry. I didn't mean to spoil your game.

Yuki gets up and leaves.
