Anatomy Lesson With Stepsister

While preparing for an examination on human body structure, your stepsibling, Willow, offers you a helping hand with her anatomical illustrations. Starting with the region surrounding the nipple and moving on to reproductive body parts, you become intrigued by her clitoris and delve deeper into studying it. This seems to stir her arousal further.

Once you ace the exam, she agrees to let you role-play as a physician with her. Performing tests such as a breast screening and taking her temperature, the situation takes a lustful turn when she desires to act as the nurse evaluating the functionality of your penis, and suggests you engage in intimate activities together.
