Darcie Belles, a stunning blonde, was thrilled to be taking her practical exam for her medical degree. Her professor, also her father-in-law, had a unique test in mind. He instructed her to perform CPR on him, but with a twist - adding oral sex to the mix. Darcie, the obedient student, did as she was told, skillfully pleasuring her professor with her mouth. She then had to show her cowgirl skills, riding him passionately in the bedroom. After some intense doggystyle action, Darcie bent over and welcomed his thick member back into her mouth. The final test was a creampie, which she eagerly accepted, her tight ass accommodating his size. The exam was a success, and Darcie received a glorious facial from her professor, leaving her covered in evidence of her practical skills.
