On the other hand, this would work great as a one-off proof of concept, demonstrating the rendering of hot models and animations in a sexy, taboo tableau. Presenting this as a short feature to demonstrate the technical and erotic potential, and then applying that skill and quality in a fresh game that builds up from the beginning of a story with new characters (rendered with the same quality and building on the same taboos), that would be perfect.
Because it's not like we don't want to see more of this. As hot and front-loaded as it was, we definitely want more. It just doesn't make sense to rewind these particular characters now that we've seen them reach the climax of their relationship. Take this quality and these themes, demonstrated excellently in this short feature, and make something full-length with buildup (not too little, not too much) and complexity, and you've got gold.
