The only thing more humiliating than a cheek gag is a cheek gag overflowing with cum.

Recommended negative if you are getting odd artifacts in your image: nosehook (unless you're using the Nose Hook LORA of course)

Use around 1.0, don't be afraid to bump up a bit with partial draws. It seems more sensitive than other LORAs to the model. ICBINP works well.

For a "Clean" gag, provide negatives: cum, white, tongue, nosehook,

Starter prompts:

subject, with a mouth retractor, mouth full of cum <lora:mouth_retractor_v1:1.0>
