Please help me find a star trek story

All I remember is that spock and kirk have to take sarek and Amanda's place as clan leader for an event. Kirk is not happy about it, but eventually accepts what he has to do with help from some pheromones that spock puts out. I think that the story is clan leader, but I am not sure if it is. I remember that their is a part 2. That is about sarek finding someone he has not seen is a longtime.
