Naughty stepson gets hardcore sex lessons from his stepmom

The scene opens with a young man, who we later find out is the stepson, lying on the bed. He is reading a book, but clearly not paying attention to it. His stepmom walks into the room and catches him reading the book. She asks him if he is reading it because he is interested in the subject matter, and he says yes. She then proceeds to explain to him that it is her book, and that she wrote it about her past sexual experiences. She then asks him if she could read it to him, and he agrees. She starts reading the book to him, but soon gets turned on and decides to show him what she wrote about. She starts to give him a blowjob, and then they start having sex. The scene progresses to a group sex orgy, where the stepmom is giving blowjobs to multiple men, while the stepson is having sex with multiple women. The scene ends with the stepmome and stepson both satisfied, and the stepson thanking his stepmom for the lesson.
