neafin~
Meaning: This can be a guy or girl, but that person does lick the asshole of another person, then both of them really seem to enjoy it! This can also be done by the same SEX, but its still not for everybody!
Example: This playful wife does enjoy sharing with guys and gals, but she'll do her neafin on both and later suck on a cock or enjoy a pussy for the finishing touch!
