Wow. This episode really emphasized how inexperienced Taketo is when it comes to girls (read: virgin). Now, there's nothing "wrong" with that--especially since he's still a kid--except that he's a genius eroge writer. The gap between concept and experience is really strong with this one.
But perhaps it's precisely because of that inexperience that his works are so successful. People want sexual desire and lust to be fanciful abstractions, not actually what it is in reality. Who would know that better than the world's biggest V-I-R-G-I-N?
