Aw thanks! Same, I definitely enjoy the oral stuff, but ironically that makes me cautious to not overdo it, so this game was actually a little dry there at first. Think it's pretty solidly supplied now though. As for mechanics, I always try to avoid being TOO samey, and the content packs especially are a good opportunity to test some stuff once I'm finished with the main game.
I actually had a bit of that "don't cum" mechanic in the first one, though it was fairly simple. I have a fairly good idea of what this last bit is going to be, but will definitely keep it in mind for future stuff.
But thanks! Glad you're enjoying it.
