Gaping, sait-elle même

Anna is reading a new book, she must be super into it. Page Turner I think they call it. I sit next to her to study biology. Yet, I need to stretch work out kinks, and pop some joints. I plant my face on the back of the couch, and perk my ass up hard and tight, while I reach back and stretch my pussy wide open. The panties are slightly down. Soon I flip back over and spread my pussy forward while exercising my mouth tongue and jaw. Anna does tickle her pussy, and adjust her undies but seriously doesn't she ever figure out what I'm doing?
