As much as I really like this, I do wish there was a way to implement the NSFW descriptions. (images not even needed)
You could get creative too if you'd like as well by writing some of your own descriptions.

Don’t know if this is what you mean by that, but the original game had a +18 version that made the game overs more explicit (text-wise). I did manage to salvage some of these game overs, but due to that version of the game being deleted a looooooooong time ago and because I was only able to find like 2 of them. I didn’t end up implementing a way to trigger them.
About that, I have found some videos showcasing quite a number of them... Perhaps you could re-create them from this footage?
