Can't say from experience, but from what I'm told, cum in the eyes stings like a bitch and is one quick way to be sent packing, especially if she said no. As an add-on, anywhere she says not to, is definitely out. As I said, I like to be invited back. I understand it's great for the complexion, but that never seems to be high up the list of reasons to let loose with a money shot anywhere special. It's warm, it's smooth, it's thick, it's sweet, it's 'HOLY FARK' don't, stop, I'm drowning, seem to be more important.
Just like doctors shouldn't say Ooops, the last thing you should be saying is, 'this wouldn't hurt a bit, did it'?
