"Oooo"  Anne wriggles a bit at the tease at her anus, the sound being one that seems to convey both a level of surprise or unfamiliarity and yet she isn't really pulling away from it.  "There you go again.  You are a naughty girl.  I think I like that."  She gives her own nipple a rolling squeeze, then lowers her hand down to dampen it between her labia, then back to her clit and starts working her fingertips over it gently, angling her pelvis so that her anus is more directly over Gweneveire's mouth. "More."
