Ugh you want to make it tough. . ok . . Well then no images, no pops, no vids, banners, etc. just contextual links.
How erotic is this stuff? Is it PG-13, R, or straight up XXX. If its not XXX you'll make money as driving them from PG/R to XXX will pay. I agree with speedhawk45, content lock rest of longer stories, link intext to adult pay, sell anything else you want to.
If this is straight up XXX then:
Clean and Simple: Find an XXX affiliate site that sells products themselves. Say your story is about erotic anal play. . . the text described (say anal beads) can be linked to the actual product. You may get some sales doing something like this . . . may.
Risky and Profitable Gold Nugget:
I'd start looking at ways to hide your link and redirect around. I'd start trying to see if you can mask it well.
DISCLAIMER:
I haven't tested this in many many years, but if you get good with your referrers than you can monetize anyway you want. You need to test and check, because if you leak 1 its over, you won't get paid. Furthermore, I'm not sure how things have changed in the past 7 years or so in reference to all this since i last looked at this, but again its just an idea, you can dig deeper and test if you are hungry for money.
E.g
Main Page XXX link --------- Goes to site1.com - Site1.com has no content and if/then redirect on it. If referrer = mainpage.com redirect to site 2. If referrer = anything else, do nothing (no one is supposed to visit this site for real). Site2.com if/then which says if referrer = Site1.com, then redirect anything you want (I bet you can think of a place that a large # of people buy from that sells adult material to a degree and would match the in-text link to that product). If not page stays same with nice content and some banner ads to those products from 'unnamed affiliate' that are supposed to be there. Think site2.com as a product review site
If you do it correctly and move your referrer properly, the user will probably never feel a disruption with the redirects. The snoopy affiliate manager will check the redirect and see its a rated PG site (Site 2) promoting these products, and never find the original traffic source. Since your traffic looks to come from site 2 - it puts them on the page that has their ad. Start with light traffic warm the account up, get paid a few months. If it goes well up the traffic.
Here is the kicker: If you understand what I"m writing then you realize that you may make affiliate cash with a lot of other products bought other than the stuff your promoting due to how often users buy from particular sites, and the way the 'cookie crumbles'.
Total risk:
1. You leak your referrer
2. that someone reports your actual site to an account manager who then vists your XXX erotic page and follows the link trail. Its pretty unlikely.
But all in all your risk is minimal considering you aren't making any cash off this page to begin with. If you got a lot of traffic you got X,XXX/mo. If you have a real lot of traffic and can plan on XX,XXX/mo., watch yourself as you would be wise to use multi accounts, or find another way to rotate in affiliates and diversify your risk, as you don' want to poke the big bears.
