Professor Izumi's Indecent Ethology-A Study of Abnormal Male Sexual Behavior in Enclosed Spaces-

Story :  I, Sae Miguchi... was recently fortunate enough to get a job helping out around Professor Izumi's lab!! Since he researches animal behavior, it's the perfect job for me, as I love animals! At least, that's what I thought. But, actually... it looks like I made a mistake when registering my profile... Just when I thought I was going to lose my job, the professor said he would let me continue to be his assistant under one condition: cooperating in his experiments! I told him if it means I can keep working here, I'll do it! But, the theme of the experiments is the study of his and my sexual behavior... what... the... heeeeeeeck!!?
While at the mercy of the professor, whose thoughts Sae cannot comprehend, she loses the power to resist his first, gentle touch...!
