Wendy and Sandy are at band practice. Wendy is sitting center row, playing a trombone. Sandy is playing a triangle, sitting directly behind her, slightly elevated. He is intensely peeking downward. We get a brief shot from his POV, staring at Wendy's butt crack.
Same man, the scene takes place more or less like the previous scene, but the little girl, after taking the coin, leads the man into a cellar. Here the little girl shows her panties again (front and back), in response the man shows her his penis leaving the little girl open-mouthed in surprise.
When the boy arrives the scene suggests that man and the little girl have done something. The boy blackmails him and gets all his money.
Same plan against another man, but this time the girl is wearing a skirt and when she bends down she shows her panties from behind. The plan works and she receives a coin.
