生物学と解剖学の教師から、体の検査を手伝って欲しいと頼まれました…

My natural sciences professor at my university wants to give me some anatomy tests; The test was that I gave her an oral and after that to see how the body works in the sexual act, what I didn't expect was that she was going to cum inside me because I have it very tight and very wet. All thanks to him.
