Trained mostly on stills from porn videos, with a few drawings mixed in. It should always make the the girl's face from roughly the nose down obscured by the POV balls. the main activator is P0vr1m, but the other tags can help too. Strength of 1 seems good, but your mileage may very. if for whatever reason you want a balls sniffing LoRA, it seems to move the girl's face up when the tag handjob is added, something i might try to change in a future version.
