Good luck, I am even too nervous to ask for services that are listed, let alone those not. In my entire life I've never received rimming, either from a civvy or a WG, and one WG I've seen a few times lists it, but I don't know how to ask for it. She licks my balls and the area just behind, feels fantastic, and I let her know how great it is "down there" as a hint, but she never goes south of tha, but I can't quite get the "Can you lick my ass" question out there.
