A fun (debatable) side story about this scene.
The Meesex scene was one I had considered doing a possible alternate path for early on during the main development process. However, I already had enough to do as it was. Plus, without the Meesex, what was the point of the scene? But, a fair number of players in the Unity thread had expressed their dislike for it (woah, woah, woah, people unhappy with anything resembling NTR, on this site?! Inconceivable!), and it wasn't one I often replayed either (I enjoyed Morticia, but was meh on the Meesex).
It's biggest impact on the game actually came in the form of the (Skip) menus that warn about the content of a scene so players can avoid things they don't care for, and I thought that would be enough. So it got shuffled into the list of, "yeah, I'd like to do more with it, but most likely it's beyond my ability to do anything about."
Fast-forward after release of r1.0 and now that I've spent more time with Morticia's overall reworks, the original Meesex scene is starting to bother me more. Add onto that Morticia is mostly absent/ignored in week 4 (due to a dwindling number of available scenes for her), and request from some players in this thread, I finally said, "fuck it, how hard can it be?" (usually the thought that proceeds a ton of work for future me...)
The answer was, actually not that bad. Pretty much all the art in it is an edit of some existing art (because, editing is all I can really do with any confidence...). It was still a lot of effort to get it together (mainly the animation at the end, removing the Meesex was very time consuming to do), but I'm mostly happy with the end result (not perfect, but good enough). And a fair number of players also seem to like the alternate path too. So, I'm glad I did it, but it's not something I'll do often.
