Hey :3, I made a more hentai like after fellatio or "cum in mouth" concept to give that effect that you'll see on hentai doujin.

You can use he following prompt as a reference:

<Lora:DigitalDelights-excessive-cum-in-mouth:1>, face focus, mouth wide open, tongue out, drool, tears, cum on hair, cum on face, cum on tongue, cum in mouth, mouth wide open, rolling eyes, (((excessive cum inside mouth))), cum on mouth, excessive cum inside mouth, cum on throat, cum overflow, bukakke, hearts, cum Accumulation inside mouth, sitting on floor, cum overflow inside mouth, mouth completely full of cum, stray pubic hairs inside mouth,

Keep in mind the (((excessive cum inside mouth))) prompt is for well more cum ;3
