Continuing her tests, your professor listens to your heartbeat as she has you stroke yourself at her guide. She asks you many questions to see if your atousal changes heart rate baseline when telling the truth or being nervous. She is so sexy as she shows off her body and even at one point has you stop stroking so she can do it for you. She wants to see how someone else arousing ou effects things in comparison to you jerking yourself off. It's scientific in part, but the hungry look in her eyes tells you she really wants more. She asks you a couple times about how you've jerked off to her, when , how often, what you imagine and more. Pulling you to baseline and then more interrogations as she talks dirty to you too. You're breathless and she seems as aroused as you are when she says this was enough data for the test, but next time she would love to fuck you and ride you with a bluetooth stethoscope and ear plugs to record how that changes you being asked questions and RHR.
