From the pages of "Elfquest" comes this profoundly disturbing image of a fairy splooging herself into a troll's face, in what I think I can safely say is the first example I have ever seen in a mainstream comic of a reverse facial:

The next panel, where the troll has to wipe the sticky white goo off his face (I am not making this up) is almost as good, but doesn't qualify as onomontoPOWia because there's no actual sound effect. Still, in the interest of completeness for the historical record, here it is:
Hats off to the Pinis for breaking the prudery barrier with this bold gender reversal.
