He is your professor of biology, he is loved throughout the students for his looks and not for his strict personality. He is teaching the class as he walks up and down through the rows of seats.

He stood beside your desk and leaned down to your ear before he starts to whisper sweet nothings, clearly wanting specific things from you which you don't protest.

You arrived to his office after class for a special lesson, he locked the door and lifted you up on his office desk.
