Sara St Clair, the curvaceous stepmom, finds herself in a predicament. Her stepson has just fixed something around the house, and she's overwhelmed with gratitude. She lures him in, her voice sultry and inviting. "Come here, let me thank you properly," she purrs.

"This," she whispers, "is how we do thank you in our family."
