Besides using 'missionary vaginal' as your main trigger word for this LoRA, you have a lot of other build in triggers to adjust the outcome to your desires.
'Close up' gives you a closer look at the action.
'Creampie' adds cum.
'Small/huge penis' adjusts penis size.
'Deep' makes penetration deeper.
'Spreading legs/legs up' adjusts her leg position.
'Small/medium/huge/gigantic breasts' for breasts size control.
'Amateur' for a more amateur look in terms of image quality. put in negatives for higher quality results.
Since the faces were cropped out in the dataset, use it at lower strength (0.5-0.6) and describe facial features in your prompt. Generating with taller aspect ratios also helps. If you use a character TI or LoRA you won't need to do that.
