Discreetly tucked in her room, the stepdaughter practises her oral skills, a secret talent she's honed at work. Her stepdad, curious, knocks and enters, finding her lips wrapped around a thick, black cock. Startled, she tries to hide it, but the evidence is clear. He's shocked, but his growing bulge betrays his interest. She sees it, and with a mischievous glint, she beckons him closer, ready to teach him the art of her secret trade.
