1: The Millionaire Next Door by Lazlo Zalezac Lazlo generally writes a great story. John Carter is a great example. Millionaire is the best, in my opinion of all his stories. It's just an incredible story.
2: Magic by Lazlo Zalezac One of the best, and funniest, stories I've ever read on SOL. One of Lazlo's better attempts.
4: Living Next Door to Heaven 1 by aroslav I haven't added a story to my favorites list in a couple of years now. That's partly because I don't read as much as I used to and partly because, what I do read, just doesn't live up to my expectations.
"Living Next Door to Heaven," has more than lived up to my expectations, and as of this writing, it's still ongoing. It is a wonderful coming-of-age story with lots and lots of good sex scenes.
5: Jared and Amanda Naked in School by Don Lockwood Don Lockwood did not originate the NiS series. In my opinion though, he wrote them the best and he also wrote the most. This was his first story to the series, it's also one of his better ones.
6: The Making Of A Gigolo (1) - Tilly Johnson by Lubrican This is the first story in a series of REALLY great stories, like a lot of my other favorites. This is the story of Bobby Dalton, a young stud in Small Town, Kansas in the 1970's. You won't believe the situation(s) this young man gets himself into.
7: Sam by Samantha K. This is a really, really good super hero story. There aren't a whole lot of super hero stories on this site but as far as I can tell, this is one of the best ones. It's long and there are three sequels now out.
