That metaphor (breasts as fruit) transcends language though. Whatever you call fruits you’ll end up calling breasts. Here’s the song of Solomon which was semetic.

I said, ‘I will go up to the palm tree; I will take hold of the boughs thereof.’ Now also thy breasts shall be as clusters of the vine, and the smell of thy nose like apples.

Instead of viewing things like this etymologically, it’s better to see them as universal metaphors that transcend language and culture. Similar to light and darkness.
