Young, inexperienced Katerina Kay visits a new doctor seeking treatment for her persistent cough. Unbeknownst to her, the doctor is obsessed with her and has other plans. He begins the examination innocently but eventually escalates to touching her intimately. Surprised and flustered, Katerina tries to resist but finds it increasingly difficult to do so as the doctor's advances continue. He then proceeds to fuck her with stubborn persistence, filling her with creampie after creampie. Despite her initial protests, Katerina eventually gives in to the pleasure, moaning loudly as she's filled up completely.
