Marcus, the foster dad, returns home to find Katie, his wife, and McKenzie, their new foster-daughter, in a compromising position. McKenzie's small tits are exposed, her hand between her legs, while Katie leans in, whispering something in her ear. Marcus's cock stirs at the sight, his foster dad fantasies coming to life. Katie notices his presence, a wicked smile spreading across her face. She beckons him, "Join us, dear. McKenzie needs to learn about consequences." Marcus hesitates, then steps in, his big dick already hard. McKenzie looks up at him, her eyes wide with curiosity and fear, as Marcus and Katie show her the true meaning of a family affair.
