Descrizione: Today was busy at the clinic, and I was catching up with some very overdue paperwork when two medical students turned up for a test exam that I had completely forgotten about. One of them was a beautiful blonde that could be very flirtatious. I started the test with some fundamental warm-up questions, which to my surprise, the lady did not know any of the answers to. This was not good for her final grade pass, which she needed from me to complete the course. I asked the gentleman to wait back in reception while I had a private word with his fellow student. As I explained that I could not pass her on the test, she asked if there was another way to change my mind. My cock instantly started to grow in my pants as the thought of licking her tight pussy was getting the better of me. I explained that this could be awkward as I also knew her father, but this did not seem to phase her as she started to rub my cock. Just as I was getting started making sure she earned this pass grade, the other student walked back into the room and caught us both in the middle of a bad situation. But, as always, a woman knows what a man wants, and soon enough, he was in on the act, and our threesome was well underway.
