...when i sit on your face ;-)
A pink ass comes over you (POV)... then Barbarelle slowly decends on his face, places his nose right in her ass-crack, the breathless time begins with a sweet and soft pressure.
Sometimes she goes a little up and changes her position, sits on his throat, moves back on his face, foreward and sideward. With every decending he gets a deep breath of her sweety odors!
