National Step Brothers Day Sia Lust and her stepbrother, Nathan Bronson, have gotten together in the past. Their fuck fest was supposed to be a secret, but Sia couldnt stop herself from sharing with her best friend, Lily Larimar. When Nathan drops into Sias room to deliver her cell phone that she left lying around, Sia gives him a hug. Lily picks up on how awkward they are and asks if its because they boned down. Nathan and Sia are unhappy with Lily for talking about it, but Lily stays the course. She claims that its national brothers day and they should therefore get together again so Sia can prove how much she appreciates Nathan being her stepbrother. When Lilys initial idea doesnt work, she isnt done. She turns to Nathan and claims that Sia says he has a really nice dick and she wants to see it. Nathan eventually gives in to Lilys pleading. Once Lily has admired the D, she begs Sia to stroke it. While Sia is doing as Lily wants, she finds that shes unbearably turned on. She needs the cock so much that she begs Nathan to give it to her, with Lilys blessing of course. On her knees, Sia takes a proper pussy pounding courtesy of Nathan as Lily watches and masturbates to the sight. They get Nathan on his back so that Sia can climb aboard and enjoy herself in cowgirl. When Sia falls onto her back, Lily manages to convince Nathan to glut his stepsis with a big ol creampie. Dripping with her stepbrothers jizz, Sia dismisses Nathan, telling him that theyre done with him. When Nathan is gone, Lily licks the cum from Sias twat. While shes enjoying her treat, she arranges herself so that her pussy is overtop of Sias mouth, creating a lesbian 69. The girls enjoy each others most tender bits for a while, but its not quite enough to make either of them cum. They get there by going pussy to pussy and tribbing together. As their scissoring brings first one and then the other to climax, they fall backwards and bask in the afterglow of a raunchy time together.
