Teacher and stepsis get down and dirty for grades. He teaches her the art of deepthroat and doggy, culminating in a messy facial. His strict rules? More like power dynamics to enhance their sexual encounter.
A young guy is really into his stepsister and has been trying to get it on with her for a long time. He's been studying hard to become a teacher, and he's been dreaming of the day when he can finally teach her. Well, that day has finally come, and he's not wasting any time. He's been waiting for her in the classroom, and when she finally walks in, he can't resist giving her a big hug. But she's not interested in hugs, she wants to know what he's been studying. He tells her about all the different ways to teach, and then he starts to teach her in a more hands-on way. He teaches her how to give him a deepthroat, and then he teaches her how to take it doggystyle. She's a natural, and soon they're both naked, ripping each other's clothes off. He teaches her how to ride him like a cowgirl, and then he teaches her how to take it in the ass. By the end of the lesson, she's covered in cum, but she's happy because now she knows how to please her stepbrother whenever he wants.
