Some keywords to use in the prompt:
This LoRA was trained on AbyssOrangeMix2 - NSFW (https://civarchive.com/models/4449/abyssorangemix2-nsfw).
The LoRAs seem to work best between 0.9 and 0.99, but even 1 produces some nice results. All of the different versions produce slightly different themed images (not intentional, but that was the result).
All versions produce slightly different themes:
Best ones to try first:
1.03/1.04/1.05
What I've found:
1.01 Tends to be the most random, not sure why.
1.02 Tends to be semi-random..
1.03 Tends to have the best double blowjob output.
1.04 Tends to have the most common occurrence of 4+ (Larger groups) and creating a man with a vagina (MtF Trans)
1.05 Tends to have a good mix of 1.03 and 1.04
You'll have to play around with the different versions of the LoRA. I've had the best luck with "-003" at 0.95 to 0.98, but even at 1 it makes produces some nice outputs. They all produce slightly different results.

Other Key Word Examples (Play around, and remove words. I've had better luck with some of the earlier words [bimmf, bisexual male, bicouple, submissive male, threesome, etc...]). You can add "Yaoi" to get more male involvement in the produced image. It tends to have more correct results (2 guys and 1 girl) with "yaoi".
