Cumming for my younger step sister

Shyla says that she has something very serious to discuss with you. Please sit and listen. As your step sister, Shyla really needs some help from you. She is 20 years old, but she looks younger than that. You think that this is kind of funny, but she is concerned because no one pays attention to her. Is it her glasses? You assure her that she should wear the glasses because they make her look hot. Shyla feels like an ugly duckling, but you assure her that she is nothing of the sort. She is sexy and she does not even realize it. Then she confesses that she has never seen a penis before. In fact, she has barely even kissed a guy before. Her virginal nature makes her that much more appealing. She has an idea. Since you two are home alone, she asks if you would mind showing her your dick. Please? Pretty please? You would be doing her a big favor, honestly. You agree to help her and you take your dick out of your pants.
