A female university lecturer changes into a leather outfit and punishes men who don’t pay attention in class and a perverted man on the train. She strips the men down to their underwear and whips them one after the other. She whips them lightly at times and suddenly hard at others, terrifying them. When a man falls to the floor from the pain of the whipping, she stomps on his face and dick with her foot, then holds his legs and stomps on his dick with her foot, making it vibrate and laughing. She makes one man get on all fours and sits on his back like a chair while whipping the other. She makes both men stand at the same time and begins whipping them, creating tension as the men don’t know which of the two will be whipped next. Each time she whips a man, she makes him say Thank You and smirks. The men regret their foolish actions, but it’s too late. Because she is a sadist and loves whipping.
