A tight skirt is a woman's weapon that shows off her panty line and accentuates her ass. On a crowded bus, she presses her ass, showing off her feminine charms, against the man's crotch, provoking him! The woman escalates, grabbing his ass from the front and from behind, burying her face in it, and then shoving her dick in! In the end, he naturally ejaculates into the tight skirt!
