Kandi's lips brushed his balls over and over...kissing and sucking at them.  She teased them with her tongue, silently marveling at their size.  Her ears heard the wet, sloppy sounds of oral pleasure, of Kristi taking their Daddy's cock into her mouth, and of their father licking at Kristi's pussy.  It turned her on even more, and Kandi took her Daddy's balls into her mouth once more...sucking and licking at them.
