I'll probably go ahead with cum_over_eye unless someone has a better suggestion. I don't really like cum_on_eyelid because there could just be a single drop of cum on the corner of an eyelid and suddenly someone would be like "oh, dat needs da cum_on_eyelid tag! Me good tagger!" When in reality that's not really the point.

I would have concerns about cum_over_eye being also tagged to characters with their eyes opens.

Also, Cum_on_eyes/cum_on_eyelids would fall in line with the rest of the cum_on* tags
