KM: alien learns you have Ultraviolet cum and thinks that is sick and wants to see it, kind of like you would react to a glow in the dark dick or whatever.
Delightful idea. Not kinky per se but I would get along well with such an alien, even if I might redirect them to some of my mutuals who might be better positioned to, er, give them a show. Also doesn't this imply that like bees should have a reaction to seeing cum? We can test this. We can do science
