Grandpa's eyes widened as his ebony granddaughter, barely legal, struts into the room, her tight body clad only in a tiny thong and a barely-there top. She's playing a dangerous game, teasing him mercilessly. She pulls her top off, revealing her firm, young breasts, and slides her thong off, revealing her smooth, shaved pussy. He's rock hard, but he knows it's wrong. She crawls onto his lap, feeling his cock through his pants, and whispers, "I want you to fuck me, Grandpa."
