TOS K/S slave fic

[bigmamag.livejournal.com]

I just read this recently and now I don't know where in the hell I found it and didn't bookmark it. Good thing I remember details, lol.

Okay, so it's AU and the Vulcans make humans slaves. Spock is one of the Vulcan warriors. The warriors are not to have women because they're a distraction, but they can have male servants like that. At the beginning Spock meets Kirk when an Andorian is brutally killed in front of the servants to discourage them from rebelling. Kirk is given to a Vulcan who abuses his power and rapes Kirk, and so do a couple of other warriors. Spock fights and wins Kirk from the dude, who is of course pissed. Spock doesn't want a consort, so he fakes that he wants Kirk for sex but instead just has him do regular servant things. They eventually trust one another and Spock discovers that humans aren't as stupid as the Vulcans seem to think because Kirk is not stupid and is quite intelligent. Kirk even almost escape twice, but the second times he chooses not to. Spock eventually gets to let Kirk train to be a servant warrior thing, and they of course fall in love. I also remember that near the end Kirk gets a new collar and he puts some of Spock's hair (it was cut off when he became a full-fledged warrior) into the weaving.

Oh PLEASE tell me someone remembers this.  D:

Mostly the fic is gratuitous porn...

So the background info is that Spock and Uhura, Jim and bones are an established couple. In the prequel to this fanfic, there's some sex pollen shenanigans involving Bones/Uhura with a side of Spock.

But the fic I'm looking for is what comes after, when Jim decides they need to resolve the mass loads of sexual tension. Basically, the four of them in a hotel room having lots and lots of sex in every possible combination. Er. Yes. Help? I swear I'm not usually this much of a perv?
