This is my attempt at creating a realistic mature woman LoRA for PONY models. Generally, the sweet spot is at 0.7-0.8, at 1 the LoRA almost completely takes over (which may sometimes be a good thing), and 0.6 and below LoRA add a slight touch.
Trigger words are "marinella" for just mature and "vintagehardcoresex" for added hardcore porn. Trigger words are not strictly required.
