"I'll put it in to check how compatible our bodies are..." Wata Mikami is a graduate student with a crush on her seminar professor, Tasuku Konoura... One day, as she's about to go home after finishing her paper, she finds her professor's lab coat left behind in the laboratory. She can't help herself from smelling the scent of the man she loves, but she gets caught in the act by Mr. Konoura himself...! "Take it all off, I want to test our compatibility based on scent." Why is he asking something so outrageous...!? Although she bears with it for the sake of research, having her nipples licked and her sensitive place teased by the man she likes makes her wet like never before... When she finally thinks that he's done with the experiment, she feels him rubbing his erection against her entrance...!? This is the start of the pleasure training between a diligent female student and a perverted genius (?) professor!
