   Summary

   Jim Kirk and Leonard McCoy are sons of rival crime families. When they begin having an affair, they agree to keep it physical only, to keep family matters off the table; they know their duty, they know one day their families will cross too many lines, that they will have to step up and lead and make decisions that hurt the other. They're grown ups, they're not stupid. And yet... if it was really just about the sex, couldn't they go elsewhere?
