A Mirrorverse Clan Leader story.  This is the story of how Spock in the Mirrorverse and his people, do not know what it means to be a Clan Leader because the information was lost in the recent violent wars involving his planet.  A series of events push Spock towards his full potential.  Can Kirk withstand the monster that his, until now, occasional bedmate, is becoming?  Warnings: contains erotica, non-consensual sex, aliens being used as sex toys by Mirror Captain (including Spock), lots of bad stuff. Contains AU characters (a Deltan and a Romulan).  If you've read Clan Leader, you know what this one is likely to get like.  Not for the faint hearted.  But there is romance (eventual and reluctant) between the evil Captain and his heartless Vulcan :)

Spock's POV, telling how he sees the danger that surrounds Jim and himself, as their love develops, and how he knows they can never be doing more than living on borrowed time.

Spock and Kirk feel an instant attraction to each other when Spock is assigned to the ISS Enterprise just before Christmas, but they each want the upper hand.  It's not about desire, it's about power.  They each battle to have sex on their own terms.

Mirror Verse.  Kirk finds a gift in his quarters.
