Who Cares That You're My Step Uncle?

When Nia Bleu invites her step-uncle Alex Mack over for a ride, she suggests he freshen up at her house. While Alex is inside, Nia reveals her considerable bosom to her step-uncle as he emerges. Startled, Alex requests that Nia cover up her sizable breasts.
Refusing, Nia interjects that they are not blood-relatives, so what is the harm?! Unable to argue with such persuasive reasoning, Alex succumbs. Nia kneels down, arousing her step-uncle with sensual oral stimulation. Proceeding to the bedroom, Nia mounts her step-uncle's sturdy member with her ample buttocks.
With each thrust, Nia's voluptuous chest heaves in rhythm, eliciting numerous climaxes. Their copulation intensity increases as Alex takes her from behind, causing Nia's magnificent rear to quiver with each forceful thrust. Finally, Alex climaxes inside Nia's mouth, sealing their taboo liaison with a vow of discretion.
