It means all he is thinking about is your breasts.
Impossible to SayThere are so many possibilities that it is impossible to say. It could be that the boy simply admires the shape and size of the breasts. It could also mean that the boy wants to do more with the girl than look at her breasts. It's also possible that the look is being misread.
If a boy looks at you it usally means he thinks you are cute, and if he thinks you are cute most likely he likes you.
No way
just checking you out.
They're siblings.
he is either embarrassed or not telling the truth... depending upon the question
I doubt it...but if he looks at you and kinda checks you out THEN he probably likes you
He hates you. that is not true that he hates you he mabe likes you
almost certainly
he looks at you a lot and he smiles at you.
He only wants your looks!
