I was not quite happy with how Illustrious deals with strap-ons, especially in solo images, I think it has regressed a bit compared to Pony. So I tried making a Lora for it, and for fun making it a bit more flexible. Trigger word is <modifier> strap-on, where modifier tends to work wit stuff which is somewhat cylindrical. It is also trained with <modifier> dildo. Trained modifiers are colors, nubbed and veiny
