Pretty new to Lora's & stuff, this is my first lora. Not explicitly guro but Ryona is close enough i hope. Made a Bellypunch Lora. Results are a bit on the gacha side so I think I need to do more research. Trigger is "harapan". Having (1boy:1.5) or some high modifier for the boy seems to make generation more consistent. Also seems to push towards exposed stomachs, I typically use a weight of 0.7~1.0. Will goto a default "shocked" facial expression if none is given in the prompt.
