There's a new version of Yiffy Age up. I'd post pictures but my gaming laptop has decided to die the Real Death and I'm afraid I may have lost a bunch of stuff. (Nothing critical though--the really important stuff is all in mods that have been published somewere.)
This version has schlong/vagina collisions, HDT balls, belly, butt, and breasts (sometimes all on the same character) and, totally unrelated, kids are pups instead of just being small adults.
There's been talk of changing around the races so all elves are felines and all humans are canines. The next version of YA will be called 3.0 and will do that. I'll also do sabercat folk instead of orcs, make the high elves cheetahs, and drop the rabbit/Lungari race. That will take a while, and I'll probably update some other mods first.
