Office workers and kids get excited by the sight of female employees wearing black pantyhose commuting to work on a crowded bus. The women can feel the excitement as their erect penises press against the plump buttocks of their tight skirts. Gradually, the movements of the hands become more erotic, and the women twitch without making a sound. The erect penis also penetrates into the pantyhose under the skirt. 10 female employees are attacked by pushing their panties aside so that other passengers don't notice.
