You are staying late after school to meet with your Biology teacher, Lina Blackly. You've failed your last exam on human reproduction, and your teacher is going to give you extra credit to help boost your grade. She shows you a diagram and a video of how reproduction works. As she is talking, you feel your cock getting hard, and she notices and likes what she is seeing. Your teacher confesses that she has seen you run, and she has been fantasizing about touching your cock and balls. She pulls down your pants and gets down on her knees in front of you. She starts to suck your balls and slobber on your cock. Using this as a learning tool, she strips down and opens her legs, showing you how reproduction works. You aggressively pump your cock into her pussy while on top before she bends over the counter, exposing her big pussy lips; you keep fucking her until your balls are drained of all its cum. You have done such a good job learning about reproduction; your teacher is so pleased that you have been such a hands-on student.
