Erotica Books

I've checked out a few books/audiobooks from Amazon..of all places. I haven't found anything really good yet. Been reading stuff from Sam Wellshauna and Vic Vitale. Vic's stuff is porn on paper, very little to no plot, one dimensional characters, and graphic sex. Sam's is a little bit better. Granted what I've read have been short stories. So I'm keeping an eye out for erotica novels...I guess. Anyway if anyone has suggestions. Let me know, and I'll keep you posted :-)
