DefinitelyNotFreeze, you're quite welcome. Just glad to help. I must admit that at first I didn't know how to do this either and had to rely on other people to help me understand just how to do so and why it was necessary. Happy to pass along what I know.
Any animal you can find in the forest will hump you. Eventually. I am certain of it. Just keep trying! Make sure you run in Doom mode as that increases the chances of animals trying to hump you.
So basically, play on Doom mode if you want the most sensual of experiences?
Don't get me wrong, Lona's cute as buttons especially when she's helping to rehabilitate Cocona but sometimes I just want to see take a cock that's not human-shaped. Horsecocks, pigporkers, dogdicks... Very few H-Game artists know what these actually look like. It irritates me no end when they advertise that their game has Bestiality content but they give all the beasts human knobs out of sheer laziness.
Damn, and I usually have it set to Hell mode instead.
