I really appreciate how the game waits to see if you're ok with feral content since a lot of people are not.
For example, the Wolf art changes if the game understands you're ok with it to show their dicks.
But you can choose to watch or not the whole thing about the lumberjack's wife.
About the Wolbauck, from what I saw and my experience from 2 differente gameplays, if you're not used or have good reputation with a feral enemy, your teasing is unlikely to work. And they just tease you if you have a good rep with them.
But is not clear from the text that you're going to see a woman banged by wolves, it says only that there are sex noises and than surprises you with a wolf
It doesn't depend on good reputation with feral enemy but with how much bestiality you do. The wolbauck is the only feral animal that if you haven't done bestiality when you click tease says something like "you don't really want to do that", while in general if you fail to tease it says something like "you make this move but it hadn't effect on him"
I agree with your first poin.
The game should really warn you about what is ahead.
It makes sense the game allows you to tease wolfs in the beggining. It your first contact with a feral animal and the game probably use it to collect data from your preferences.
By the way, if you're not really into feral, choosing the tease option once won't do a thing, since the animals will not tease you back at least you have a good rep with them.
