Xiao has a nicely shaped belly button. Kassy always wanted to get a closer look. Touch. Lick. Maybe even more. Now that Xiao is without a boyfriend she allows Kassy to play with her bellybutton. She starts off by rubbing and caressing the surrounding area, then she inserts her fingers into it. As Xiao seems to like it more and more Kassy brings her vibrator. She has a special custom made head for it, thats perfect for bellybutton insertion. Once the machine is in and Kassy puts it in high gear it doesn't take long for Xiao to cum.
