The stepmoms put a birthday tiara and sash on Leah, and all three of them gush about how happy they are to be a family. Leah then begins flirting with them, and mentions something about a family tradition.It's revealed that Nadia's family has a tradition that includes having sex with stepdaughters when they turn 18, so the stepdaughters will feel empowered and ready to face the world. Leah, Cory, and Nadia have been excitedly waiting for this day. The two stepmoms lovingly kiss Leah, then explore her breasts, and give her 18 spanks to celebrate her adulthood. And that's just the beginning of this very special tradition!
