Matt walks into the classroom late and without his school uniform. Miss Charlie is furious with him and makes him drop his trousers so she can put him across her knee in full view of the three girls in the class! She spanks him and then as it is a human biology class she leads him by his penis from desk to desk so the girls can have a close up look at his cock and balls! With precum oozing out of his cock, the girls use their rulers to measure his penis and then ask the teacher what happens when he gets aroused.
