"I bet I could clean the window with my tongue better than you!"

"Ew? But no. You absolutely could not" she stated firmly as she stood up and marched over to the window. She pressed herself against it, her tongue moving around the glass... As were her giant tits.

"Aaakh a oook aah iih!" Yang tried to say despite her tongue being out. Jaune could barely make out that she intended to say "Take a look at this" as if she was showing off her... Skills...
