HEYZO-1111 — Secret Entrance Exam ~Welcome To The Department Of Seminal Biology!~ - Mari Koizumi

She thought she came to take the exam for the Biology Department, but it turned out to be the Sperm Department!? Exam-taker Mari Koizumi wanders into a suspicious department filled with a strange old man in a white coat. He immediately touches her breasts, tears her pantyhose, and finally orders her to pee in the classroom. As expected of a Sperm Department, if she doesn't check out how she urinates properly, she'll be in trouble when she becomes a university student. There's a mountain of things to learn, like how to suck a penis and how to use tools, so it's tough. Although she was confused at first by the many erotic lessons, she gets used to them by the second half and of course the end is the expected creampie finish!
