A very consistent LoRA do generate a woman next to a spankingmachine.

The spankingmachine not always in action, but often.

The girls have sometimes visible spanking marks, if you add whip_marks to Pony-Checkpoints more often. SDXL generate some, but sometimes change them to ropes or other lines.

Example prompt:
1girl, solo, sexy latina, spanked, whip_marks, spankingmachine, bent over
