Full Summary: It's been a Terran year since Vulcan's destruction and the Vulcan race is still unsettled. There's been an outbreak on the colony: Vulcan men of all ages are going through Pon Farr years earlier than expected. No one knows why this is happening.
Sarek is recalled to the colony to investigate the outbreak... and to prepare for the fact that he might face Pon Farr without his wife Amanda. On route to New Vulcan, the scientific exploration vessel he is on is destroyed, and he is forced to crash land on an uninhabited planet with the other survivors of the explosion. As the blood fever burns through him, he grows closer to a Human woman named Winona Kirk.
Spock has experimented with his humanity in a way that no Vulcan ever would: he enjoys casual sex. And when Jim Kirk declares that he wants sex, Spock decides the seducing his captain will be beneficial to both of them... not that it takes anything more than a well-placed comment to attract Jim's attention. When faced with a situation where he must pretend that their casual sex is anything but casual, Spock discovers he doesn't mind the idea, but Jim is not the kind to do commitment. He must help investigate the Pon Farr outbreak while dealing with the fact that he will never bond with the one he loves... who is also now his stepbrother.
Short Summary: There has been a Pon Farr outbreak on New Vulcan. Sarek goes to investigate but is trapped on an uninhabited planet with Winona Kirk just as he begins Pon Farr himself. Spock and Jim save their parents, only to discover that they are now stepbrothers. Dealing with the outbreak, their parents' new relationship, and their own friends-with-benefits relationship will challenge both of them.
