Updated version. Trained on a larger variety of images, more focused on extreme versions of the face and requires less trigger words. V1.0 will consistently provide the best results. Any trigger words will include a penis if you add "fellatio" or "oral". Do not add either if you just want the face without a blowjob. Adding "open mouth" and "tongue out" provides results as can be seen in the examples.
Use "EXBJFace" as general trigger.
Adding the fellatio or oral tags is enough. Instead of EXBJFace, use "EXBJMax" to get the most extreme length faces consistently. Adding "gigantic lips" and "gigantic mouth" will increase width.
Instead of EXBJFace, use "EXBJNoodle" to get long but thin mouths, as can been seen in the examples. All trigger words work with or without fellatio tags.
