Does boob masturbation ever actually happen?

I don't know what its real name is and thought t-i-t w-a-n-k would be censored so there it is: boob masturbation. I'm 16 and the closest I've ever got with a girl is a kiss and that's only happened once but by golly gosh she was a stunner! My friend, with a tally of two carved onto his wooden bed said that "Ti* w*nks don't really exist outside of porn apart from in really rare cases, for starters, when the woman actually has large enough boobs. Blow jobs used to be the same. Only the slags would hand them out but with more people watching porn all lassies are handing them out like there's no such thing as water or any other form of drink or alternative such as things like Tomato Puree which could pass as water". Ignoring the last part is what he said true? And have you ever had/ given out 'boob masturbation'? Thanks.
