"Appleseed" by Wollstonecraft (an285729@anon.penet.fi). Joey is a rich guy who is a generally nasty bastard and whose attitude toward girls is not only to "lay 'em and leave 'em" but also to get 'em pregnant in the process. This story describes how he routinely exploits teenage girls for this purpose. The author's style is vivid, and he uses verb tenses in such a way as to convince us that while he is vividly describing a specific situation he is really describing Joey's typical behavior.

Actually, he's not really Joey; the guy makes up new names and new cover stories to suit his particular seductive needs. He finds it especially easy and enjoyable to pick up religious girls at church activities; they're invariably extremely gullible. The only constant is that he is an asshole who wants to get young girls pregnant. He's even scientific about his process - in one case seducing a pair of identical twins and conducting a seductive experiment with them in a way that a Nazi genetic engineer might admire.

Nonconsensual seduction and rape are not funny in the real world. But this story is very well told and extremely enjoyable. I can't tell you more details, because a major part of the enjoyment is watching the story unfold. I strongly recommend this story.
