Yeah, and I still think it is very well written, the characters are interesting (apart, perhaps, from the over the top fight between the husband and wife in chapter two), world building is fleshed out and believable and the mystery itself is enticing. This could probably work as a non porn game and that makes it a rare gem indeed in this genre.
But as for my criticism of the size of the MC:s dick, it still stands. The lazy rendering in my view, is not taking relative objects size into account. So, for instance, in the blow job scene with Annie, you can compare the dick with her face, as it is more or less perfectly lined up (we shouldn't experience any distortion based on one object being closer to the "camera" than the other). The average length of a womans face, from the point of the chin to the hairlline is about 7 inches. That means that had the cock been 7 inches, it should have been the same lenght as Annies face. But is it? No, not even close. Instead, the dick is about two thirds of Annies face, when taken into account that her mouth is open and her face therefore elongated. That would instead put the dick around slightly longer than 4 inches. Substantially smaller than the male average. And girth-wise (the thing women typically care more about), it feels correspondingly thin.
The other scenes are harder to gauge, since it's not exactly clear how close to each other different body parts are, but I get the same feeling from them.
As for going from flaccid to erect, I think it would look better if there were other differences between semi-flaccid and erect state other than size. Now, the fully erect dick look exactly the same as the semi flaccid dick, only bigger. Most cocks don't just grow, they change shape and look (for instance, going from pudgy to taut, changing colour and/or growing more prominent veins). But that's a minor detail compared to the MC having smalish genitalia.
