Bouton de pom-pom girl

Catherine is about to leave for practice when her friend Terra gets intrigued by her exposed tummy. She is even more excited to see that this outfit leaves her belly button bare. As Terra's tongue begins to explore the depth of her navel, Catherine concedes that the extra attention feels nice, even if it is a little tickly. The wetter her tummy gets, the more excited Catherine becomes. Who can think about practice at a time like this?
