First version.

Warning
expect a lot of failed images. We're battling the AI here, cause it doesn't think you should put your hands in other peoples mouths (and it might have a point, but eh...). Also, as you probably know, fingers and hands is not what AI does best.

Make sure to do the following
use either "sticking hand into females mouth" or "sticking fingers into females mouth" in your prompt. And make sure the word "penis" is not in your positive prompt - it will either produce normal blowjob pictures or replace male hands/arms with penises (you can try that for fun, but it'll get boring pretty fast.)
