Jiniya, Main reason could be that he truly likes your boobs! But it does not means that he might have been loving you! We guys like to ogle at all the body of a women all curves and valiilies !More curveceous a woman more lusty stares she gets! And it is not our fault as we have been made naturally that way! But doing it so blatently is not acceptable!
If you do not like his stares ask him upfront that you do not like him always stareing at you if you both are friendly enough or give him angry stares when you catch hin stareing and you too take precautions to dress properly so by mistake you are not exposing your boobs or clevage ! Wear tighter bra so your breasts would not protude ! Also do not use reverse colors like black bra under white exterier(contrasting colors) as it extentuates the beauty of those lovely mounds!
