After a long day playing games with your rough and tumble older sister, she gets bored and wants to make out. It's really not a big deal - apart from the fact that you've never kissed anyone before. She offers to teach you how to kiss so when you DO have your first kiss, it'll be good. It's probably a good thing for you to learn some other things, too.
