He said "see penetration", not "see implied penetration". I'm close to the end of the current build, and I haven't seen even ONE explicit penetration (dick, pussy lips, ass ring, etc) in the entire game where the camera clearly shows genitals from both people, and I've pursued as many scenes as I can. It's all just implied - we never get to actually see anything except blowjob penetration explicitly.
At least creampies are becoming a thing now. The whole money shot thing isn't my bag. And implied sex scenes (basically soft porn) are highly disappointing. I'm hopeful the developer can change course and actually spend more time working on sex animations to get all the "parts" involved. Seems like a cop-out to save time on the posing/animation setup, but I'm just guessing.
