So this is a branch out from my other fetish, (facesitting/farting), and the creator of the game was kind enough to put kissing attacks in the game as well! If you enjoy kissing enough to weather out my other fetish (which is more pronounced in the game), then go ahead and give this a shot. If not, then I understand.
So far all the enemies that I have found with a kissing attack are the bunny girls, nekos, and the boss of the nekos. There may be more out there but those are the only ones I have found.
