1: Sam by Samantha K. This is the best erotic superhero story I've ever read. The beginning had a lot of stuff that made me go squick (turned off) but i stuck with it, and it got so much better! The beginning is really just the origin story. As an origin it's unique.
This entire series had just been incredible, and something i tend to reread every year or so.
If you really want to test how broad minded you are when it comes to sexuality and erotica, try the stallion girl series by this same fantastic author.
3: Time by John Wales One of the better do over stories out there.
4: The Dipsomaniac Inventor by Howard Faxon Anything by Howard Faxon is going to be good. This one is one of the funniest. Isaac Asimov had a similar plot to a series of short stories, but I think Howard does it better.
5: Magic by Lazlo Zalezac In this list simply for its pure comedy, this story is fantastic.
I can recommend pretty much everything Lazlo has ever written.
Go read the John Carter and Jade Force series if you don't believe me.
6: John Carter by Lazlo Zalezac This is the first of a series. It covers the return of Gods to an active part of mankind's life in the modern world. The return is spearheaded by the druidic pantheon and their earthly servant John Carter.
7: Life on Isekai Easy by BlueDirk Ok, the first chapter needs some minor proofing but this is not a story where that matters. This is a comedy, and if you've read a few (hundred) Isekai, as i have, you'll find this hilarious, I really hope the author keeps writing.
