By far one of my favourite BJ scenes. The interactivity, the sounds, the animations, everything screams quality and creativity. It is fairly receptive to custom characters, but it unfortunately struggles with some height/proportion differences. However, this is easily circumvented with some creative manipulation and all in all I cannot overstate how much I recommend it.
Anxiously awaiting more updates!
Now that I think about it, I have not touched that animation at all since the beginning, could be better. I'll add that to the to-do list :p
