Or analingus or something else but I think you get the idea. BTW, I'm referring to the customer doing it to the lady.
I understand the risks with things like hepatitis and intestinal parasites, although I guess you could use covering. It's obviously better if you practice this with an SO or someone you can trust so you have a little degree of safety if you do it uncovered.
Do any men here like doing this? Do any women here allow this?
