I've added a "horsecock futa" addon today, check out this small video.

There's no balls physics yet, and it's going to be pretty hard to make it, because of "sexy walk" animations, with almost zero space between her legs.
The texture is not finished, i'm gonna improve it too. It's actually pretty hard to find a proper color for cock here, to make a good looking blend with skin color.

P.S. My page is "unpaused" now. I'm gonna start working with BTQ4 soon, after i finish some import stuff for the game.
