I recently discovered an ongoing comic/story called "Sunstone" by Shiniez. It's some of the best writing I've ever seen in this genre and has set a new bar for me personally. The writing is witty, sexy, and knows when to show and when to tell. The art is pretty amazing too.
I understand it's available for purchase on Amazon, but I've been reading it on DeviantArt (requires a free account). It's worth checking out. Look left for individual chapters.

I agree this is an excellent ongoing comic, well written and beautifully drawn, you can really get into the characters.
Yes, I have to agree too.
Sunstone for those who may not have kept up, yes this is a necro-thread resurrection, Sunstone is now in print and has a follow up series Mercy.
Several Story arcs are in the works.
