Hinting for a kiss?

So I like this guy, and I spend a lot of time with him because our families are friends. And I think he might like me too. How can I hint that I want him to kiss me? Or hint that I like him? I mean, I do my best at flirting but i don’t know if I’m doing it right. And I can’t just be like “KISS ME YOU FOOL” and I can’t just kiss HIM because... I’m a chicken.
