Kendall's in such a playful and erotic mood, it's getting her so horny to fool around with Sierra and jiggle each other's asses. The intimate fun of their tickling and teasing is the perfect prelude to hot, passionate sex. Sierra gets so turned by the feeling of soft, plump ass-cheeks, nuzzling her face right in there as she licks up and down Kendall's crack from behind. She slides her mouth up and down between the lips, flicking the tip of her tongue over the clit.
