The Home of Spock/McCoy Fiction
The Sixth Installment in The Bonded Souls Series. Spock and McCoy invite the bridge crew to a barbeque at their house. While Spock and McCoy prepare for visitors and celebrate their union, the rest of the crew contemplate their coming out that happened a year before.
Cadet McCoy believed Professor Spock was out to get him due to him always giving him such a hard time. To "get him off his ass" he asked his friend Nyota for help. "This is a hand gesture in Vulcan. It means that you aren't intimidated by him. This should get him to leave you alone." Too bad the gesture for that and to show sexual interest were strikingly similar.
