What? Pussy to Mouth is just a variation of Ass to Mouth which has always meant pulling out of Pussy/Ass and putting it in the womans Mouth. There's no reason to change that phrasing at all.
If you say so. I had no idea and im fucking 30 chronically online and a porn addict so.... must not actually be that common both of those make it sound like you're gonna put your mouth to ass or pussy. Not her cleaning herself off of you.
