Well, it might be kinky, depending on what your kinks are. Personally, I think the pumps are damn hot. o.o And there is some sort of subconscious fixation to milk that a lot of people seem to share.
But humans in general are meh. (Don't get me wrong- I have no opinion on animals or something like that. It's just that humans are meh.)
Multibreasts are indeed a kinky, and one that I don't share. I don't like it, I don't hate it; I really just don't care. It's more the size that matters. And those... are too big. I'm not ENTIRELY sure, but my preference runs in the A-B cup range. Small and perky are lovable.
I admit that large breasts are DAMN comfortable, but the actual sex appeal is less. And the amount of pain it causes a woman doesn't seem worth it.
