Master Eraqus is sitting in the library, quietly researching a book. He hears a noise, yet sees nothing when he looks. He hears another noise: footsteps. Even after looking towards the source, he doesn't see anybody. Suddenly, he turns his head around to see Ven sitting on the table, which makes him nearly fall off his chair.
Eraqus: Ven! You shouldn't be sneaking around like that.
Ven: Sorry, master.
Eraqus: Do you need something?
Ven: Yeah...there's something I want to know.
Eraqus: Well, what is it?
Ven: What's sex?
The color drained from the master's face. He always feared this day would come. The Keyblade Master had hoped that at some point Xehanort taught Ven about the birds and the bees, and he would just remember it. Unfortunately, that wasn't the case.
Eraqus: Where did you hear that term?
Ven: Terra and Aqua were saying something about it earlier today.
That didn't surprise him. After all, his two older students were near the end of their teenage years. One would assume that it was only natural to bring up that topic now and then.
Eraqus: Erm, well sex is...let's see, how could I say this...sex is a lot like a diet.
Ven: Huh?
Eraqus: In one form or another, all people's diets consist of food and water. Similarly, sex involves a man and a woman. Well, not all the time, I suppose...
Ven stared at him, dumbfounded.
Ven: Sorry, but I'm not following you, master.
Eraqus scratched his head.
Eraqus: Well, normal sex involves two people, a male and a female. And basically, one lays on top of the other, and-
Ven: This isn't anything gross, is it?
Eraqus realized how difficult this was going to be. Not only that, but he was about to solve a huge mystery about the Keyblade War, one that not even Xehanort had known thus far. But if he was trying to explain life's mysteries to Ven, that wouldn't happen.
Eraqus: You know what, go ask Terra. I'm sure he'll explain it to you.
Ven: Okay!
Being the fastest apprentice, Ven sprinted out of the library and up to Terra's room in mere seconds. He was about to knock when he heard voices coming from the room.
Terra: That's it, Aqua. Just a little further.
Aqua: Like this?
Ven swung open the door.
Ven: Hey Terra, are you showing her a new Keyblade-
His mouth gaped open at the sight. Aqua, in her undergarments, was lying on Terra, who was dressed similarly. Embarrassed, the two dived under the covers. Aqua held up the blanket to cover her top.
Terra: VEN?! WHAT ARE YOU DOING HERE?!
Ven: Oh...so that's sex?
The next morning, Eraqus sat happily in the dining room. A delicious breakfast assortment was set on the table. Ven entered the room, taking a seat next to the master. The master was happy that he had solved his mystery from the previous night. Although, he couldn't help but wonder if his apprentice had solved his mystery.
Eraqus: So, Ven, did Terra tell you what sex was?
Ven: Yeah! He even showed me!
Eraqus was shocked. Did his two male pupils have intercourse?
Eraqus: He showed you?
Ven: Yeah, him and Aqua.
The comment completely replaced Eraqus's confusion with rage. Terra entered the room with a smile.
Terra: Ah, what a great night!
He turned to Eraqus, noticing the angry expression.
Terra: Guess I can't say the same for you, eh master? Haha.
Eraqus: TERRA!!!!
The boy gulped. Unsure of whether his master was angry at the comment or something else, he braced himself for a lecture.
