I have thought about it.
I'm not adding it. I think text by itself is more arousing than images. I like erotica. Using images to me would feel like a crutch and I wouldn't be so descriptive. Honestly I think it would detract from the experience.
Plus, it would take a lot of time to do that and for it to look good. I'm a perfectionist and I would only accept the best looking art.
Finally, my ancient PC can't run Stable Diffusion. My machine is like 10+ years old. I would have to ask someone else to do the work for me.
So, very definitively: Sorry, but it's not happening. This game will always be text-only.
