Luscious goes door to door to sell her magic oil that makes the part you rub bigger, whatever that part is. As a demonstration, she shows Johnny her ass and rubs it with oil and he notices an augmentation in her booty. But being comfortable with his member, Johnny refuses to buy oil. She doesn't believe that he is big so she goes to check it from closer. Johnny will ram his monster cock in her without the use of that magic liquid just to prove that he does not require the oil.
