For his birthday, Mike decided to break a taboo and invited his associate's 18-year-old sister over. She's petite, innocent-looking, but with a perverted twist. Mike watches, hard as a rock, as she takes off her clothes, revealing her small, firm tits and smooth pussy. She kneels in front of him, her big, doe eyes looking up at him as she takes his cock into her virgin mouth. She's a quick learner, slurping and sucking like a pro, her tiny hand pumping his shaft in rhythm.
