Correctional nurse Lau is a really strict woman. She her little prison girl Mau into a waist chain, cuffs her hands behind her back, tells her to get on her knees and worship her high heels. As if that is not enough punishment, Lau makes Mau lie on her stomach, and she quickly cuffs the ankle cuffs to the waist chain, leaving poor prison girl Mau in a very tight arched hogcuffing. Then comes the tickling and teasing... what a nurse!! This is mean girl at its best!
