Claire continued kissing her younger daughter, running her tongue over the girl's bottom lip before slipping her tongue into Cassy's mouth and wrestling with her tongue while her sister watched the two of them. Cracking her eye open as she heard Lisa moving around she saw the girl moving between her sister's thighs and starting to lick her pussy, unaware of her mother watching with a faint blush dusting her cheeks until Lisa would feel Claire's fingers running through her hair when she pulled back to catch her breath. Looking down at the older sister Claire finally said "Come sit beside me Lisa, i'm going to teach you and Cassy properly.." as she patted the bed on her other side while looking at her two daughters.
