A Lesson in Reproduction

You visit your professor before class to ask for some help revising for the upcoming reproduction test but it's not long before hearing her talk about the details of sexual intercourse gives you an accidental boner. Far from being annoyed by it, she tells you a secret. She gets turned on by the subject matter too, why do you think she loves teaching this class so much? She reassures you that it's all perfectly natural. You're just a young man with urges and she's just a horny MILF who happens to be ovulating right now.
