She is forced to stay in the hospital, where she is examined by two sexually harassing doctors. They play with Kei's genitals again and again. At night in the hospital room, she is given an aphrodisiac and seeks out the penis of the perverted old doctor, shaking her hips and finally getting creampied. And the obscene examination never ends...
