I will say though don't read it if you can't tollerate BDSM. Ai no Kusabi is a Slave/Master story afterall so there's a fair bit of that in there.
The fan fic takes place before the anime starts and has an alternate ending for those who have seen it but didn't like the ending (like me)
If you havent seen the anime, don't worry it's still a good read on it's own but there are a few things to know
Anime News Network
The barren world Amoi was terraformed and settled centuries ago by scientists seeking to create an ideal civilization. Instead, their supercomputer, Jupiter, attained consciousness and then went mad.
The society Jupiter created is a bizarre one. Women are rare. A person's status is determined by their hair color, with the "Blondies" the ruling elite. The Blondies are genetically engineered to be both stronger and smarter then the oridinary human, but are sterile. They keep human "Pets", which are specially bred and trained for the task (the males are tagged with rings around their penises), for voyeuristic entertainment - and "Furniture", castrated males from the slums who serve as bodyguards for Blondies and their pets. Favored pets are kept in condos in the rich suburb of Eos. On the opposite end of the spectrum from the elites are "mongrels" from the slum city of Ceres, who reproduce naturally and are not even registered "citizens". The people in Ceres are descendants of a group who had rebelled against Jupiter but failed and were cast out of Tanagura, Amoi's capitol city.
Iason Mink is one of the highest of the elite, a leader of Tanagura, a man in direct contact with Jupiter. Riki "The Dark" is a slum-dwelling non-citizen at the bottom of the caste system, and the leader of the Bison gang. When Iason saves Riki from some vigilantes, Riki offers his body, the only thing he has to give, as payment.
And so when Iason decides to take Riki, a mongrel, as his favorite pet, rumors fly and the social infrastructure is shaken. Riki is too old to be a pet (he's 17 to 20 during the time covered in the story), wasn't trained or raised to be a pet and isn't even a citizen. Plus, Iason has no intention of letting him go (most pets are only kept for a year) and even has sex with him (which is taboo). And then there's Riki's jealous ex-lover...
