I don't know why so many fans are having problem with Luke and Leia being siblings.
And the kiss in ESB really isn't any kind of romantic kiss. It is basically just an angry reaction from Leia to shut up Han.
1. It wasn't planned. It was a band-aid after Lucas decided he was going to quit after ROTJ.
2. Luke has had a thing for Leia since SW77. Even going so far as to play on her sympathies to get more smooches on at least two occasions. =P
