When the girls from the all-girls schools in the city get cold, they start wearing black stockings here and there. The eroticism of bare legs disappears, but the inside of the school uniform skirt becomes irresistibly erotic. In the footage of schoolgirls on stairs, there is a big focus on the eroticism of these black stockings. They have filmed extensively up to the inside of the school uniform skirts as they climb the stairs. The images of the girls' underwear seen through the black stockings are very revealing.
