Whiplash 2 (1998)

Two beautiful sisters find themselves the gagged, restrained patients of the Cracker clinic, a rehab center where young beauties are held in captivity, while their insurance companies are bilked for big money. After an on the job car accident, pretty Jody Goth is sent to the Cracker clinic to get rehab for her sore neck which she injured in the accident. She needs to get an exam to file for her workman's comp. What she gets instead is groped, bound, gagged and beaten by the fiendish Dr. Nuegent, the newest addition to the clinic's demented staff. While Jody is inside the clinic suffering countless indignities at the hands of Dr. Nuegent, which include a digital exam, forceps clamped on her large, tender nipples and several foreign objects shoved down her throat to check the "strength of her jaws", her beautiful sister Vanessa is waiting impatiently in the car for her. But what was taking so long?
