When she tells her boyfriend about the situation, he denies it and says, "You're lying!" The fat store manager, who hears from her dissatisfied with her boyfriend's personality and sexual behavior, says, "I can please you more," and they begin having sex in the waiting room on a weekday night when there are few customers. The chubby store manager, whose penis remains erect even after ejaculation, makes the beautiful woman with beautiful legs scream, and seduces the young girl not with his looks but with his seasoned sex techniques!
